Abstract
A large body of researches has demonstrated that cultural values directly influence the success of organizational strategies and managerial actions. On the same way, the successful use of Lean Manufacturing (LM) practices requires more than the use of tools. Although many manufacturing facilities worldwide use LM practices, dimensions of nation’s culture and leadership may moderate the expected results from the LM implementation. Using LM background and cultural data, this paper presents the results of an exploratory study on the moderation of Lean Leadership effectiveness by dimensions of national cultural values. The study was based on the feedback from the practice of Lean Leadership in various multinationals based in Morocco. A questionnaire was elaborated, validated, and sent to overall 120 respondents holding various management and operational positions in many multinational companies. The results of this study are used to identify directions for proposing an adapting model of operations management to the Moroccan SMEs.

Effect of fiber distance on various sac ocdma detection techniqueseSAT Journals
Abstract Optical code division multiple access system (OCDMA) has been gaining importance with increasing demands of high speed and large capacity for communication in optical networks. OCDMA system is totally asynchronous, that does not require any clock signals for synchronization in the network. Therefore, OCDMA provide a network that is simpler and offers the potential for scalability to higher levels of connectivity. OCDMA encoding /decoding process also provides a level of security directly implemented in the physical layer. Using OCDMA technique high spectral efficiency is achieved, hence fiber bandwidth is used very efficiently with throughput in excess of Tbit/s. Among several kinds of OCDMA systems, spectra amplitude coding (SAC) scheme attracts increasing interest because multiple access interference (MAI) can be eliminated and preserve the orthogonality between users in the system. This paper presents comparison of three important SAC-OCDMA detection techniques, namely - Direct detection, Complementary subtraction and AND subtraction. The design of encoder and decoder modules for SAC-OCDMA system used in this paper is based on Fiber Bragg Gratings (FBGs). Here conventional single mode fiber (SMF) is used as the transmission link and the performance metric studied is Quality factor (Q) in multiple access environments of various user systems for these three detection techniques. Finally Effect of increasing number of fiber distance on the direct detection technique using NRZ and RZ data formats have been studied. Simulated results show that AND subtraction technique gives better Quality-factor (Q) than the complementary subtraction and direct detection techniques for the signal with same power. Index Terms: OCDMA (optical CDMA), BER (bit error rate), MAI (multiple access interference), DW (double weight code), SAC (spectral amplitude coding) and Q (quality factor)
Numerical analysis of geothermal tunnelseSAT Journals
Abstract
Geothermal energy is a good alternative of fossil fuels and its usage is the most innovative and useful technology that contributes to environmental protection and provides substantial energy, long term cost savings and minimized maintenance. Geothermal energy can be extracted or injected to the earth through tunnels, where tunnels acts as a heat exchanger, in which absorber pipes are fitted, which are circulated with heat transfer liquid. In cities, tunnels provide access for rail, road and utilities. They can also be used as ground heat exchanger for GSHP (Ground Source Heat Pump) systems. Tunnels dug underground use geothermal power to bring our home temperature to earth temperature, i.e helps in heating and cooling. The concept for the thermal tunnel utilizes the temperature difference between the ground and inlet temperature, via compression (heating) or expansion (cooling), to generate building heating or cooling. The system is reversible and operated at best efficiency between seasons. Response of the tunnel as a element has to be recorded and studied. ABAQUS is finite element software (FEM) used for the analysis. Study deals with the simulation of geothermal tunnels using ABAQUS, involving heat transfer analysis and coupled thermo-mechanical analysis using a 3-D model. The model has been analysed for finding out thermal stresses, temperature and displacements on concrete lining, embedded pipes and the soil in which tunnel is being constructed. Results are generated in the form of various plots after running the analysis for a duration of 8 years.

Implementation of content based image retrieval using the cfsd algorithmeSAT Journals
Abstract Content-based image retrieval (CBIR) is the application of multimedia -processing techniques to the image retrieval problem, that is, the problem of searching for digital images in large databases. There is a growing interest in CBIR because of the limitations inherent in metadata-based systems. The most common method for comparing two images in CBIR is using an image distance measure based on color, texture, shape and others. In this paper, we describe an object-oriented graphical implementation of a system, backed by a My SQL database, that computes distance measures using the CFSD algorithm, based on color similarity
Unravelling the molecular linkage of co morbid diseaseseSAT Journals
Abstract ABSTRACT : The incidence of Diabetes Mellitus (DM), Hypertension (HTN) and Coronary artery disease (CAD) in the country has increased alarmingly. Since decades DM and HTN have been proved to be independent risk factors for CAD. Gene and its regulatory action through a protein are vital for the normal metabolism. Any abnormality in regulation would lead to a disease. Our study used the principles of network biology to understand the comorbidity of diseases at the molecular level. We have collected disease genes of DM, HTN and CAD from various public databases and extracted genes common to all the three diseases. We constructed a biological network by considering the protein interaction data obtained from Human Protein Reference Database (HPRD).The network was validated using power law distribution and the genes were ranked using Centiscape. Finally we identified the crucial genes with literature validation which could play a major role in causing disease co-morbidity.

Abstract A large number of structures that are being constructed at present tend to be wind-sensitive because of their slenderness, shapes, size, lightness and flexibility. With the ever increase in the vertical growth of urban cities, high rise buildings are being constructed in large numbers. In this study, analytical investigation of different shapes of buildings are taken as an example and various analytical approaches are performed on the building. These plans are modeled and wind loads are found out according to I.S 875(part 3)-1987 by taking gust factor and without taking gust factor. These models are compared in different aspects such as storey drift, storey displacement, storey shear, etc. for different shapes of buildings by using finite element software package ETAB’s 13.1.1v. Among these results, which shape of building provide sound wind loading to the structure as well as the structural efficiency would be selected.

Beam steering in smart antennas by using low complex adaptive algorithmseSAT Journals
Abstract Array antenna systems are often used to enhance the received signal to interference and noise ratio when the signal operates in heavily jammed environment. Proper modeling of the received data at different antenna elements is important when evaluating the performance of this system, especially when both the signal and interference have wide frequency bands.. The antenna output is the linear combination of data from all the antenna elements. In conventional narrowband beam forming, time sequences at different antenna elements are related by some fixed phase shift. The phase shift is determined by the wave forms direction of arrival (DOA). In this paper, an efficient method for the pattern synthesis of the linear antenna arrays with the prescribed nulling and steering lobe is presented. The proposed method is based on Least Mean Square (LMS) algorithm provide a comprehensive and detailed treatment of the signal model used for beam forming, as well as, describing adaptive algorithms to adjust the weights of an array. In order to improve the convergence rate of LMS algorithm in smart antenna system, in this paper we proposes a new normalized LMS (NLMS) algorithm, This new algorithm can be treated as a block based simplification of NLMS algorithm which gives satisfactory performance in certain applications in comparison with conventional NLMS recursion, i.e., BBNLMS algorithm. By taking advantage of spatial filtering, the proposed scheme promises to reduce the bandwidth required for transmitting data by improving convergence rate. The performance of the BBNLMS algorithm in the presence of Multi-path effects and multiple users is analyzed using MATLAB simulations. The simulations when compared to that of the LMS algorithm, the results suggest that BBNLMS algorithm can improve the convergence rate and lead to better system efficiency. Keywords: BBNLMS, Convergence Rate, DOA, LMS, NLMS, Smart antenna.
Visible light solar photocatalytic degradation of pulp and paper wastewater u...eSAT Journals
Abstract
With the growing number of industries there are large volumes of wastewater generated every day. Pulp and paper mills are highly polluting as they release effluents containing organic pollutants, and high levels of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). Even though well-established processes exist to treat these effluents, there are only a few processes which are energy efficient. Conventional treatment methods are not effective for the degradation of toxic organic pollutants, hence other treatment techniques are necessary. One of the recent developments in this field is the Advanced Oxidation Process (AOP). Solar photocatalysis is a type of AOP which utilises UV light to activate semiconductor photocatalyst in order to produce highly reactive radical species. TiO2 is a widely used catalyst for this purpose, to oxidise or reduce the organic pollutants in industrial wastewater. However, photocatalysis using visible light has been receiving increased attention hence, modification of TiO2 is necessary for its enhanced response to visible light. There are many methods for modifying TiO2, such as doping and photo-sensitisation. This study focusses on the modification of TiO2 using the method of dye-sensitisation (photo-sensitisation) with the dyes rhodamine B and methylene blue. Solar photocatalytic experiments were carried out for the degradation of pulp and paper wastewater, at different conditions like varying catalyst loading (500mg, 600mg, 750mg and 1000mg of catalyst for 300ml of aqueous wastewater) and effluent concentration (20ml, 25ml, 30ml and 35ml of wastewater). Preliminary tests were done to determine the best conditions for photocatalytic degradation, and these were applied for final tests. Keywords - Solar Photocatalysis, Visible Light, Dye Sensitisation, Pulp and paper, Methylene blue, Rhodamine B, TiO2 catalyst.
A new approach for generalised unsharp masking alogorithmeSAT Journals
Abstract We propose a new generalized algorithm using the exploratory data model as unified frame work. Enhancement of contrast and sharpness of an image is required in many applications. In applications like medical radiography enhancing movie features and observing the planets it is necessary to enhance the contrast and sharpness of an image. Unsharp masking is good tool for sharpness enhancement; it is an anti blurring filter. By using unsharp masking algorithm for sharpness enhancement, the resultant image suffering with two problems, first one is a hallo is appear around the edges of an image, and second one is rescaling process is needed for the resultant image. The aim of this paper is to enhance the contrast and sharpness of an image simultaneously and to solve the problems. In the proposed algorithm, we can adjust the two parameters controlling the contrast and sharpness to produce the desired output. The proposed algorithm is designed to address issues:1) simultaneously enhancing contrast and sharpness by means of individual treatment of the model component and the residual,2)reducing the halo effect by means of an edge-preserving filter using Bilateral filter. Experimental results, which comparable to recent published results, shows that proposed algorithm is able to significantly improve the sharpness and contrast of an image. This makes the proposed algorithm practically useful. Index Terms: Bilateral filter, edge-preserving filter, exploratory data model, Image Enhancement, Unsharp Masking

Emotional telugu speech signals classification based on k nn classifiereSAT Journals
Abstract Speech processing is the study of speech signals, and the methods used to process them. In application such as speech coding, speech synthesis, speech recognition and speaker recognition technology, speech processing is employed. In speech classification, the computation of prosody effects from speech signals plays a major role. In emotional speech signals pitch and frequency is a most important parameters. Normally, the pitch value of sad and happy speech signals has a great difference and the frequency value of happy is higher than sad speech. But, in some cases the frequency of happy speech is nearly similar to sad speech or frequency of sad speech is similar to happy speech. In such situation, it is difficult to recognize the exact speech signal. To reduce such drawbacks, in this paper we propose a Telugu speech emotion classification system with three features like Energy Entropy, Short Time Energy, Zero Crossing Rate and K-NN classifier for the classification. Features are extracted from the speech signals and given to the K-NN. The implementation result shows the effectiveness of proposed speech emotion classification system in classifying the Telugu speech signals based on their prosody effects. The performance of the proposed speech emotion classification system is evaluated by conducting cross validation on the Telugu speech database. Keywords: Emotion Classification, K-NN classifier, Energy Entropy, Short Time Energy, Zero Crossing Rate.

Effect of packing material and its geometry on the performance of packed bed ...eSAT Journals
Abstract Surface roughness is the most prominent factor in machining of any metal. The efficacy of a machining process is largely dependant on quality of surface roughness obtained for the workpiece. This experiment involves turning of AISI 1040 steel under dry, conventional cutting fluid (wet) and cryogenic condition using high speed steel cutting tool. The surface roughness values for each of the trials were measured and recorded.Taguchi’s signal-to-noise (S/N) ratio was introduced to this experiment inorder to determine the significant control factor (cutting speed, feed rate or depth of cut) for all three machining processes along with the optimal control factor combination. The control factors were set in an orthogonal array (L27). MINITAB 16 was used to determine the S/N ratio valuesfor all the different interactions by incorporating “smaller the better” characteristic. The analysis concluded that the significant control factor for dry machining was feed rate, depth of cut for conventional cutting fluid (wet) machining and feed rate for cryogenic machining. Feed rate of 0.10mm/rev,depth of cut of 0.25mm and cutting speed of 43.73m/minare the optimumcontrol factor combination to be set to procure minimum surface roughness in each of the machining process. Even though the optimum combinations were observed to be same for all the machining process, there was an improvement of 53.57% in cryogenic machining observed in analogous to dry machining and an improvement of 33.92% in cryogenic machining was observed in correspondent to wet machiningfor S/N ratio values of optimum control factor combinations. It was also observed that the S/N ratio values for optimum combination (minimum surface roughness) in cryogenic machining were the least in analogous to other forms of machining. Thus this developed model concludes that the dip cryogenic machining should be adapted in order to procure minimum surface roughness.

Effect of fiber distance on various sac ocdma detection techniqueseSAT Journals
Abstract Optical code division multiple access system (OCDMA) has been gaining importance with increasing demands of high speed and large capacity for communication in optical networks. OCDMA system is totally asynchronous, that does not require any clock signals for synchronization in the network. Therefore, OCDMA provide a network that is simpler and offers the potential for scalability to higher levels of connectivity. OCDMA encoding /decoding process also provides a level of security directly implemented in the physical layer. Using OCDMA technique high spectral efficiency is achieved, hence fiber bandwidth is used very efficiently with throughput in excess of Tbit/s. Among several kinds of OCDMA systems, spectra amplitude coding (SAC) scheme attracts increasing interest because multiple access interference (MAI) can be eliminated and preserve the orthogonality between users in the system. This paper presents comparison of three important SAC-OCDMA detection techniques, namely - Direct detection, Complementary subtraction and AND subtraction. The design of encoder and decoder modules for SAC-OCDMA system used in this paper is based on Fiber Bragg Gratings (FBGs). Here conventional single mode fiber (SMF) is used as the transmission link and the performance metric studied is Quality factor (Q) in multiple access environments of various user systems for these three detection techniques. Finally Effect of increasing number of fiber distance on the direct detection technique using NRZ and RZ data formats have been studied. Simulated results show that AND subtraction technique gives better Quality-factor (Q) than the complementary subtraction and direct detection techniques for the signal with same power. Index Terms: OCDMA (optical CDMA), BER (bit error rate), MAI (multiple access interference), DW (double weight code), SAC (spectral amplitude coding) and Q (quality factor)
Numerical analysis of geothermal tunnelseSAT Journals
Abstract
Geothermal energy is a good alternative of fossil fuels and its usage is the most innovative and useful technology that contributes to environmental protection and provides substantial energy, long term cost savings and minimized maintenance. Geothermal energy can be extracted or injected to the earth through tunnels, where tunnels acts as a heat exchanger, in which absorber pipes are fitted, which are circulated with heat transfer liquid. In cities, tunnels provide access for rail, road and utilities. They can also be used as ground heat exchanger for GSHP (Ground Source Heat Pump) systems. Tunnels dug underground use geothermal power to bring our home temperature to earth temperature, i.e helps in heating and cooling. The concept for the thermal tunnel utilizes the temperature difference between the ground and inlet temperature, via compression (heating) or expansion (cooling), to generate building heating or cooling. The system is reversible and operated at best efficiency between seasons. Response of the tunnel as a element has to be recorded and studied. ABAQUS is finite element software (FEM) used for the analysis. Study deals with the simulation of geothermal tunnels using ABAQUS, involving heat transfer analysis and coupled thermo-mechanical analysis using a 3-D model. The model has been analysed for finding out thermal stresses, temperature and displacements on concrete lining, embedded pipes and the soil in which tunnel is being constructed. Results are generated in the form of various plots after running the analysis for a duration of 8 years.

Abstract Content-based image retrieval (CBIR) is the application of multimedia -processing techniques to the image retrieval problem, that is, the problem of searching for digital images in large databases. There is a growing interest in CBIR because of the limitations inherent in metadata-based systems. The most common method for comparing two images in CBIR is using an image distance measure based on color, texture, shape and others. In this paper, we describe an object-oriented graphical implementation of a system, backed by a My SQL database, that computes distance measures using the CFSD algorithm, based on color similarity
Unravelling the molecular linkage of co morbid diseaseseSAT Journals
Abstract ABSTRACT : The incidence of Diabetes Mellitus (DM), Hypertension (HTN) and Coronary artery disease (CAD) in the country has increased alarmingly. Since decades DM and HTN have been proved to be independent risk factors for CAD. Gene and its regulatory action through a protein are vital for the normal metabolism. Any abnormality in regulation would lead to a disease. Our study used the principles of network biology to understand the comorbidity of diseases at the molecular level. We have collected disease genes of DM, HTN and CAD from various public databases and extracted genes common to all the three diseases. We constructed a biological network by considering the protein interaction data obtained from Human Protein Reference Database (HPRD).The network was validated using power law distribution and the genes were ranked using Centiscape. Finally we identified the crucial genes with literature validation which could play a major role in causing disease co-morbidity.

Abstract A large number of structures that are being constructed at present tend to be wind-sensitive because of their slenderness, shapes, size, lightness and flexibility. With the ever increase in the vertical growth of urban cities, high rise buildings are being constructed in large numbers. In this study, analytical investigation of different shapes of buildings are taken as an example and various analytical approaches are performed on the building. These plans are modeled and wind loads are found out according to I.S 875(part 3)-1987 by taking gust factor and without taking gust factor. These models are compared in different aspects such as storey drift, storey displacement, storey shear, etc. for different shapes of buildings by using finite element software package ETAB’s 13.1.1v. Among these results, which shape of building provide sound wind loading to the structure as well as the structural efficiency would be selected.

Beam steering in smart antennas by using low complex adaptive algorithmseSAT Journals
Abstract Array antenna systems are often used to enhance the received signal to interference and noise ratio when the signal operates in heavily jammed environment. Proper modeling of the received data at different antenna elements is important when evaluating the performance of this system, especially when both the signal and interference have wide frequency bands.. The antenna output is the linear combination of data from all the antenna elements. In conventional narrowband beam forming, time sequences at different antenna elements are related by some fixed phase shift. The phase shift is determined by the wave forms direction of arrival (DOA). In this paper, an efficient method for the pattern synthesis of the linear antenna arrays with the prescribed nulling and steering lobe is presented. The proposed method is based on Least Mean Square (LMS) algorithm provide a comprehensive and detailed treatment of the signal model used for beam forming, as well as, describing adaptive algorithms to adjust the weights of an array. In order to improve the convergence rate of LMS algorithm in smart antenna system, in this paper we proposes a new normalized LMS (NLMS) algorithm, This new algorithm can be treated as a block based simplification of NLMS algorithm which gives satisfactory performance in certain applications in comparison with conventional NLMS recursion, i.e., BBNLMS algorithm. By taking advantage of spatial filtering, the proposed scheme promises to reduce the bandwidth required for transmitting data by improving convergence rate. The performance of the BBNLMS algorithm in the presence of Multi-path effects and multiple users is analyzed using MATLAB simulations. The simulations when compared to that of the LMS algorithm, the results suggest that BBNLMS algorithm can improve the convergence rate and lead to better system efficiency. Keywords: BBNLMS, Convergence Rate, DOA, LMS, NLMS, Smart antenna.
Visible light solar photocatalytic degradation of pulp and paper wastewater u...eSAT Journals
Abstract
With the growing number of industries there are large volumes of wastewater generated every day. Pulp and paper mills are highly polluting as they release effluents containing organic pollutants, and high levels of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). Even though well-established processes exist to treat these effluents, there are only a few processes which are energy efficient. Conventional treatment methods are not effective for the degradation of toxic organic pollutants, hence other treatment techniques are necessary. One of the recent developments in this field is the Advanced Oxidation Process (AOP). Solar photocatalysis is a type of AOP which utilises UV light to activate semiconductor photocatalyst in order to produce highly reactive radical species. TiO2 is a widely used catalyst for this purpose, to oxidise or reduce the organic pollutants in industrial wastewater. However, photocatalysis using visible light has been receiving increased attention hence, modification of TiO2 is necessary for its enhanced response to visible light. There are many methods for modifying TiO2, such as doping and photo-sensitisation. This study focusses on the modification of TiO2 using the method of dye-sensitisation (photo-sensitisation) with the dyes rhodamine B and methylene blue. Solar photocatalytic experiments were carried out for the degradation of pulp and paper wastewater, at different conditions like varying catalyst loading (500mg, 600mg, 750mg and 1000mg of catalyst for 300ml of aqueous wastewater) and effluent concentration (20ml, 25ml, 30ml and 35ml of wastewater). Preliminary tests were done to determine the best conditions for photocatalytic degradation, and these were applied for final tests. Keywords - Solar Photocatalysis, Visible Light, Dye Sensitisation, Pulp and paper, Methylene blue, Rhodamine B, TiO2 catalyst.
A new approach for generalised unsharp masking alogorithmeSAT Journals
Abstract We propose a new generalized algorithm using the exploratory data model as unified frame work. Enhancement of contrast and sharpness of an image is required in many applications. In applications like medical radiography enhancing movie features and observing the planets it is necessary to enhance the contrast and sharpness of an image. Unsharp masking is good tool for sharpness enhancement; it is an anti blurring filter. By using unsharp masking algorithm for sharpness enhancement, the resultant image suffering with two problems, first one is a hallo is appear around the edges of an image, and second one is rescaling process is needed for the resultant image. The aim of this paper is to enhance the contrast and sharpness of an image simultaneously and to solve the problems. In the proposed algorithm, we can adjust the two parameters controlling the contrast and sharpness to produce the desired output. The proposed algorithm is designed to address issues:1) simultaneously enhancing contrast and sharpness by means of individual treatment of the model component and the residual,2)reducing the halo effect by means of an edge-preserving filter using Bilateral filter. Experimental results, which comparable to recent published results, shows that proposed algorithm is able to significantly improve the sharpness and contrast of an image. This makes the proposed algorithm practically useful. Index Terms: Bilateral filter, edge-preserving filter, exploratory data model, Image Enhancement, Unsharp Masking

Emotional telugu speech signals classification based on k nn classifiereSAT Journals
Abstract Speech processing is the study of speech signals, and the methods used to process them. In application such as speech coding, speech synthesis, speech recognition and speaker recognition technology, speech processing is employed. In speech classification, the computation of prosody effects from speech signals plays a major role. In emotional speech signals pitch and frequency is a most important parameters. Normally, the pitch value of sad and happy speech signals has a great difference and the frequency value of happy is higher than sad speech. But, in some cases the frequency of happy speech is nearly similar to sad speech or frequency of sad speech is similar to happy speech. In such situation, it is difficult to recognize the exact speech signal. To reduce such drawbacks, in this paper we propose a Telugu speech emotion classification system with three features like Energy Entropy, Short Time Energy, Zero Crossing Rate and K-NN classifier for the classification. Features are extracted from the speech signals and given to the K-NN. The implementation result shows the effectiveness of proposed speech emotion classification system in classifying the Telugu speech signals based on their prosody effects. The performance of the proposed speech emotion classification system is evaluated by conducting cross validation on the Telugu speech database. Keywords: Emotion Classification, K-NN classifier, Energy Entropy, Short Time Energy, Zero Crossing Rate.

Effect of packing material and its geometry on the performance of packed bed ...eSAT Journals
Abstract Surface roughness is the most prominent factor in machining of any metal. The efficacy of a machining process is largely dependant on quality of surface roughness obtained for the workpiece. This experiment involves turning of AISI 1040 steel under dry, conventional cutting fluid (wet) and cryogenic condition using high speed steel cutting tool. The surface roughness values for each of the trials were measured and recorded.Taguchi’s signal-to-noise (S/N) ratio was introduced to this experiment inorder to determine the significant control factor (cutting speed, feed rate or depth of cut) for all three machining processes along with the optimal control factor combination. The control factors were set in an orthogonal array (L27). MINITAB 16 was used to determine the S/N ratio valuesfor all the different interactions by incorporating “smaller the better” characteristic. The analysis concluded that the significant control factor for dry machining was feed rate, depth of cut for conventional cutting fluid (wet) machining and feed rate for cryogenic machining. Feed rate of 0.10mm/rev,depth of cut of 0.25mm and cutting speed of 43.73m/minare the optimumcontrol factor combination to be set to procure minimum surface roughness in each of the machining process. Even though the optimum combinations were observed to be same for all the machining process, there was an improvement of 53.57% in cryogenic machining observed in analogous to dry machining and an improvement of 33.92% in cryogenic machining was observed in correspondent to wet machiningfor S/N ratio values of optimum control factor combinations. It was also observed that the S/N ratio values for optimum combination (minimum surface roughness) in cryogenic machining were the least in analogous to other forms of machining. Thus this developed model concludes that the dip cryogenic machining should be adapted in order to procure minimum surface roughness. Keywords –AISI 1040 steel, dry machining, wet machining, cryogenic machining, surface roughness and Taguchi’s approach

While leadership styles were not significantly related to overall AQ, certain dimensions of AQ (like reach) influenced aspects of transformational leadership. The study aimed to help business leaders improve their resilience and ability to handle adversity through understanding their leadership styles and AQ.

Mechanical properties of hybrid fiber reinforced concrete for pavementseSAT Journals
Abstract
The effect of addition of mono fibers and hybrid fibers on the mechanical properties of concrete mixture is studied in the present
investigation. Steel fibers of 1% and polypropylene fibers 0.036% were added individually to the concrete mixture as mono fibers and
then they were added together to form a hybrid fiber reinforced concrete. Mechanical properties such as compressive, split tensile and
flexural strength were determined. The results show that hybrid fibers improve the compressive strength marginally as compared to
mono fibers. Whereas, hybridization improves split tensile strength and flexural strength noticeably.
Keywords:-Hybridization, mono fibers, steel fiber, polypropylene fiber, Improvement in mechanical properties.
Material management in construction – a case studyeSAT Journals
Abstract
The objective of the present study is to understand about all the problems occurring in the company because of improper application
of material management. In construction project operation, often there is a project cost variance in terms of the material, equipments,
manpower, subcontractor, overhead cost, and general condition. Material is the main component in construction projects. Therefore,
if the material management is not properly managed it will create a project cost variance. Project cost can be controlled by taking
corrective actions towards the cost variance. Therefore a methodology is used to diagnose and evaluate the procurement process
involved in material management and launch a continuous improvement was developed and applied. A thorough study was carried
out along with study of cases, surveys and interviews to professionals involved in this area. As a result, a methodology for diagnosis
and improvement was proposed and tested in selected projects. The results obtained show that the main problem of procurement is
related to schedule delays and lack of specified quality for the project. To prevent this situation it is often necessary to dedicate
important resources like money, personnel, time, etc. To monitor and control the process. A great potential for improvement was
detected if state of the art technologies such as, electronic mail, electronic data interchange (EDI), and analysis were applied to the
procurement process. These helped to eliminate the root causes for many types of problems that were detected.

Life cycle cost analysis of overlay for an urban road in bangaloreeSAT Journals
Abstract
Pavements are subjected to severe condition of stresses and weathering effects from the day they are constructed and opened to traffic
mainly due to its fatigue behavior and environmental effects. Therefore, pavement rehabilitation is one of the most important
components of entire road systems. This paper highlights the design of concrete pavement with added mono fibers like polypropylene,
steel and hybrid fibres for a widened portion of existing concrete pavement and various overlay alternatives for an existing
bituminous pavement in an urban road in Bangalore. Along with this, Life cycle cost analyses at these sections are done by Net
Present Value (NPV) method to identify the most feasible option. The results show that though the initial cost of construction of
concrete overlay is high, over a period of time it prove to be better than the bituminous overlay considering the whole life cycle cost.
The economic analysis also indicates that, out of the three fibre options, hybrid reinforced concrete would be economical without
compromising the performance of the pavement.

Influence of reinforcement on the behavior of hollow concrete block masonry p...eSAT Journals
Abstract
Reinforced masonry was developed to exploit the strength potential of masonry and to solve its lack of tensile strength. Experimental
and analytical studies have been carried out to investigate the effect of reinforcement on the behavior of hollow concrete block
masonry prisms under compression and to predict ultimate failure compressive strength. In the numerical program, three dimensional
non-linear finite elements (FE) model based on the micro-modeling approach is developed for both unreinforced and reinforced
masonry prisms using ANSYS (14.5). The proposed FE model uses multi-linear stress-strain relationships to model the non-linear
behavior of hollow concrete block, mortar, and grout. Willam-Warnke’s five parameter failure theory has been adopted to model the
failure of masonry materials. The comparison of the numerical and experimental results indicates that the FE models can successfully
capture the highly nonlinear behavior of the physical specimens and accurately predict their strength and failure mechanisms.

Influence of compaction energy on soil stabilized with chemical stabilizereSAT Journals
This document summarizes a study on the influence of compaction energy on soil stabilized with a chemical stabilizer. Laboratory tests were conducted on locally available loamy soil treated with a patented polymer liquid stabilizer and compacted at four different energy levels. The study found that increasing the compaction effort increased the density of both untreated and treated soil, but the rate of increase was lower for stabilized soil. Treating the soil with the stabilizer improved its unconfined compressive strength and resilient modulus, and reduced accumulated plastic strain, with these properties further improved by higher compaction efforts. The stabilized soil exhibited strength and performance benefits compared to the untreated soil.

This document summarizes an experimental study that tested circular concrete-filled steel tube columns with varying parameters. 45 specimens were tested with different fiber percentages (0-2%), tube diameter-to-wall-thickness ratios (D/t from 15-25), and length-to-diameter (L/d) ratios (from 2.97-7.04). The results found that columns filled with fiber-reinforced concrete exhibited higher stiffness, equal ductility, and enhanced energy absorption compared to those filled with plain concrete. The load carrying capacity increased with fiber content up to 1.5% but not at 2.0%. The analytical predictions of failure load closely matched the experimental values.
Evaluation of punching shear in flat slabseSAT Journals
Abstract
Flat-slab construction has been widely used in construction today because of many advantages that it offers. The basic philosophy in
the design of flat slab is to consider only gravity forces; this method ignores the effect of punching shear due to unbalanced moments
at the slab column junction which is critical. An attempt has been made to generate generalized design sheets which accounts both
punching shear due to gravity loads and unbalanced moments for cases (a) interior column; (b) edge column (bending perpendicular
to shorter edge); (c) edge column (bending parallel to shorter edge); (d) corner column. These design sheets are prepared as per
codal provisions of IS 456-2000. These design sheets will be helpful in calculating the shear reinforcement to be provided at the
critical section which is ignored in many design offices. Apart from its usefulness in evaluating punching shear and the necessary
shear reinforcement, the design sheets developed will enable the designer to fix the depth of flat slab during the initial phase of the
design.

Estimation of surface runoff in nallur amanikere watershed using scs cn methodeSAT Journals
Abstract
The development of watershed aims at productive utilization of all the available natural resources in the entire area extending from
ridge line to stream outlet. The per capita availability of land for cultivation has been decreasing over the years. Therefore, water and
the related land resources must be developed, utilized and managed in an integrated and comprehensive manner. Remote sensing and
GIS techniques are being increasingly used for planning, management and development of natural resources. The study area, Nallur
Amanikere watershed geographically lies between 110 38’ and 110 52’ N latitude and 760 30’ and 760 50’ E longitude with an area of
415.68 Sq. km. The thematic layers such as land use/land cover and soil maps were derived from remotely sensed data and overlayed
through ArcGIS software to assign the curve number on polygon wise. The daily rainfall data of six rain gauge stations in and around
the watershed (2001-2011) was used to estimate the daily runoff from the watershed using Soil Conservation Service - Curve Number
(SCS-CN) method. The runoff estimated from the SCS-CN model was then used to know the variation of runoff potential with different
land use/land cover and with different soil conditions.

Abstract The nonlinear Static procedure also well known as pushover analysis is method where in monotonically increasing loads are applied to the structure till the structure is unable to resist any further load. It is a popular tool for seismic performance evaluation of existing and new structures. In literature lot of research has been carried out on conventional pushover analysis and after knowing deficiency efforts have been made to improve it. But actual test results to verify the analytically obtained pushover results are rarely available. It has been found that some amount of variation is always expected to exist in seismic demand prediction of pushover analysis. Initial study is carried out by considering user defined hinge properties and default hinge length. Attempt is being made to assess the variation of pushover analysis results by considering user defined hinge properties and various hinge length formulations available in literature and results compared with experimentally obtained results based on test carried out on a G+2 storied RCC framed structure. For the present study two geometric models viz bare frame and rigid frame model is considered and it is found that the results of pushover analysis are very sensitive to geometric model and hinge length adopted.

Abstract
Depletion of natural resources and aggregate quarries for the road construction is a serious problem to procure materials. Hence
recycling or reuse of material is beneficial. On emphasizing development in sustainable construction in the present era, recycling of
asphalt pavements is one of the effective and proven rehabilitation processes. For the laboratory investigations reclaimed asphalt
pavement (RAP) from NH-4 and crumb rubber modified binder (CRMB-55) was used. Foundry waste was used as a replacement to
conventional filler. Laboratory tests were conducted on asphalt concrete mixes with 30, 40, 50, and 60 percent replacement with RAP.
These test results were compared with conventional mixes and asphalt concrete mixes with complete binder extracted RAP
aggregates. Mix design was carried out by Marshall Method. The Marshall Tests indicated highest stability values for asphalt
concrete (AC) mixes with 60% RAP. The optimum binder content (OBC) decreased with increased in RAP in AC mixes. The Indirect
Tensile Strength (ITS) for AC mixes with RAP also was found to be higher when compared to conventional AC mixes at 300C.

The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

Abstract
A large body of researches has demonstrated that cultural values directly influence the success of organizational strategies and
managerial actions. On the same way, the successful use of Lean Manufacturing (LM) practices requires more than the use of
tools. Although many manufacturing facilities worldwide use LM practices, dimensions of nation’s culture and leadership may
moderate the expected results from the LM implementation. Using LM background and cultural data, this paper presents the
results of an exploratory study on the moderation of Lean Leadership effectiveness by dimensions of national cultural values. The
study was based on the feedback from the practice of Lean Leadership in various multinationals based in Morocco. A
questionnaire was elaborated, validated, and sent to overall 120 respondents holding various management and operational
positions in many multinational companies. The results of this study are used to identify directions for proposing an adapting
model of operations management to the Moroccan SMEs.
Keywords: Survey, Lean Manufacturing, Lean Leadership, National culture, Organizational culture, Multinational,

1. INTRODUCTION
LM is more a philosophy than just a toolbox; it is a fully
integrated management and manufacturing philosophy and
approach [2]. However, it also made clear, that the tools are
important, but the basic tenet of LM is that lean culture and
Lean Leadership are the most important factors.
Additionally, the strong balance among technological
efficiency and leadership effectiveness has been largely
considered as the limit that separates success and failure of
LM implementation projects [22], [40], [38], [11], [17], [8],
[44]. Taking into account that cost pressure seems to force
organizations to relocate work into low cost countries, like
Morocco, an investigation of LM perceptions, risk factors
on the lean pathway proves very important. In absence of
studies and research in Morocco related to LM, there is no
clear evidence of the level of success and problems/barriers
in the LM implementation in those organizations. Some
problems/ barriers that might cause company to stumble
may root of the leadership of management [36] and the
specific national culture who can indirectly influences
leadership behaviors differently to LM requirements [19].
Because the national cultures are quite diverse, and the ways
of practicing leadership seem to be subject to the influence
of the social and cultural environment in which they are
used, the resulting organizations and the work systems are
equally diverse [41].
Thus, the purpose of this study is to explore the status of
Lean Leadership maturity in multinational facilities based in
Morocco. Especially, the status aims to discover the
perception of managers toward the LM in terms of
understanding of the concepts, the assumption of Lean
Leadership roles, and to confirm the hypothesis of a role of
national culture in nurturing the lean culture and its
influence on the Lean Leadership maturity.
The following section reviews the literature and related
theory to LM, Lean Leadership, and the cultural impact.
Next we describe the data, sample, and measures. We then
discuss the results. Finally we point out the contributions to
both the academic and more to the practitioner literature.
2. LITERATURE REVIEW
2.1 Lean Manufacturing and Lean Leadership
Lean Manufacturing (LM) is often regarded as the most
important strategy for manufacturing firms desiring to
achieve world-class performance [24]. LM is a collective
term for production practices aimed at increasing value
creation and reducing waste in all forms. LM refers to an
integrated social-technical system whose main objective is
to eliminate waste by concurrently reducing or minimizing
supplier, customer, and internal variability [47]. Therefore,
the main objective of LM is to achieve maximum efficiency,
carrying out operations at a minimum cost and with zero
waste [40].

Volume: 04 Issue: 02 | Feb-2015, Available @ http://www.ijret.org 543
However, any transfer of organization or management
techniques is also a transfer of leadership profile and
organizational culture [39]. Although manufacturing
facilities worldwide use LM practices, dimensions of
leadership and nation’s culture my moderate LM results
[33]. According to [35], LM programs fail because
managers have confused lean solutions for the process that
led to what we see in a Toyota factory and specific Lean
Leadership that daily involved employees in these
processes. [17] introduced the Lean Leadership as a
methodical system for the sustainable implementation and
continuous improvement of the LM. Lean Leadership is a
continuous process that involves making followers want to
contribute to continuous improvement and process
excellence. This includes the customer orientation,
proximity management, as the long-term development of
employees. To be able to transform the entire organization
into a lean organization, the Lean Leadership must be,
assimilated, understood, and modeled across all
management levels.
2.2 Lean Manufacturing Practices, National and
Organizational Culture
Managers are encouraged to implement LM practices
globally because of its universal effectiveness. However, as
a successful implementation of any continuous improvement
demarche can only be achieved if the employees believe in
the change that is about to happen, the implementation
process of the LM needs to be adjusted to specific external
and internal characteristics of each organization [3]. So, for
the expected performance of the LM, several behavioral
adjustments and managerial interventions may be necessary
in each LM adoption. This implies that the form and use of
such LM practices as waste reduction, 5S, and just-in-time,
may be guided by the underlying cultural values of
managers and workers in a facility [48].
Given that countries vary in their cultural values [30],
incongruence between national culture and lean culture may
corrupt the practice of LM and moderate expected
performance improvements [33]. In his research on the
moderation of LM effectiveness by dimensions of national
culture, and by analyzing data from more than 1400
facilities in 24 countries, [33] confirms that LM is more
effective in a future-oriented (FO), performance-oriented
(PO), and assertive national culture (AS). Likewise, [25], in
his analyze of the cultural lean inhibitor impact breakdown,
suggests that the cultural barriers affect all the five aspects
of LM (The Value, Value stream, Continuous Flow,
Customer Pull, and Perfection). Therefore, when there is no
tension between national and lean culture, LM practices are
easier to implement and hence will have higher
performance. In contrast, divergence between national and
lean culture could make implementing LM problematic.
Nevertheless, in the GLOBE study about leadership
effectiveness and culture, [19] argue that national culture
does NOT predict leadership behavior or organizational
culture included lean culture. Too, [44], in his study of 189
manufacturing plants between Eastern (Japan and south
Korea) and Western (Germany, United States, Finland, and
Sweden) countries, indicates that organizational culture has
more an effect on manufacturing performance than national
culture, and in result, a weak influence of national level
factors on manufacturing performance. Likewise, [7], in his
research about the role of organizational culture in LM,
sustains that a specific organization culture profile
characterizes all successful lean plants; Thus plants,
compared to unsuccessful lean plants, show an
organizational culture marked by more institutional
collectivism (IC), a strong future orientation (FO), and a big
human orientation (HO). Yet, [4] and [41], argument that
the “culture of work” matters more than national culture in
the degree to which manufacturing practices can be applied
across countries. In an era of globalization, these results
have practical implications for national organizations and
organizations expanding across national boundaries by
developing an internal organizational culture consistent with
LM requirements whatever the culture of the country of
relocation
3. RESEARCH AND DATA ANALYSIS
3.1 Sample Selection and Analysis Approach
The empirical research took place end of 2014. The data was
captured through meticulous survey questionnaires
undertaken in various multinationals based in Morocco
whose production processes related to automotive and
aeronautic manufacturing. Although the companies targeted
were international, staff will predominantly be Moroccan,
enhancing our ability to identify national cultural influences
on our findings. The survey questionnaire items were
developed based on LM background, Lean Leadership
fundamentals, and cultural data. The survey questionnaire
was split into the following categories with several or more
questions in each category to determine:
- the perception about the LM,
- the critical practices of Lean Leadership,
- behavioral effects of Lean Leadership on the shop floor,

In total, 41 questionnaires have been returned, of which two
had to be discarded because of insufficient data, yielding 39
usable questionnaires (34% response rate). Table.1 provides
an overview of the responses by sector, by multinational
origin, by function, and by hierarchical level of respondents.
The majority of the respondents to the survey were
managers (53%) and supervisors (31%). Two hierarchical
positions enhancing our ability to identify critical Lean
Leadership behaviors. Finally, 50% of factories are French,
25% Japanese, 17% German, and 8% American.

First we analyzed the LM perception as a result of the
understanding of LM philosophy using descriptive statistic.
The questions were created on basis of various literature
studies [50], [34], [22], [43], [30], [2], [45], [32]. Table.2
shows respondent views about LM perception.
Unfortunately, an important conclusion was the reduction of
lean concepts in a toolbox to reduce lead time (78.26%) and
improve operations (60.87%), not in a fully integrated
management and manufacturing philosophy (21.74%)
focused on customer satisfaction (21.74%) trough the
organization and management of product development,
operations, suppliers and customer relations (26.09%).
Another interesting aspect is that only 17.39% seed the LM
as a way to create new work and business; a significantly
lower result than founded among our European neighbors
evaluated at 42% [2]. As previously outlined, looking at the
fact that through reducing the ultimate goal of lean to
reducing the lead time it has to be said that quit a
remarkable managers does not yet fully see the chances and
potential of LM implementation [3]. Thus, unless managers
in the company ignore about the potential of LM,
improvement initiatives are less likely to be initiated and the
miraculous gains in performance through LM are less likely
to be reached.
Next, as mentioned earlier, we tried to understand, and
predict the impact of specific national cultural values on
Lean Leadership and LM practices and the effectiveness of
these practices. Eight questions were formulated on the basis
of the Lean Leadership literature review [50], [34], [35],
[45], [16], [17], [40], [11], [38] to investigate about the
critical Lean leadership practices in national culture and
leadership values context. The results are summarized in
Table.3.

The findings about difficulty average number indicate that
managers moderately assumed the quality of product, and
moderately encouraged the shop floor employees to stop the
line in any case of quality deviation with the same difficulty
average number (47.83%). Thus result provides other
finding about the large difficulty for supervisors to put
quality above productivity and efficiency (52.66 %). Also,
the results indicate that managers and supervisors are less
performing in motivating and supervising, training, and
facilitating the work in the shop floor with a difficulty
average number of 57.49%. This study indicates also an
average difficulty of 55.56% for managers and supervisors
to encourage and participate with employees in both process
and performance indicators improvement projects.
Unfortunately, research among successful organizations
indicates that results are better if performance managements
is focused on supporting improvement rather than just for
monitoring and control the shop floor. Changes in the role
and behavior of top and middle management by less
information flow stagnation, transparency, direct contact
with the shop floor, and continuous management support to
workers are considered the cornerstone of successful LM
implementation. Likewise, as [22] note, management
practices, such as employee involvement in continuous
improvement programs, employee integration in problem-
solving teams, and employee training, are acknowledged to
form core components of a LM program. Such as Lean
Leadership literature advocates that management should
function as a facilitator rather than supervisor [44],
managers have to support the continuous improvement
culture by living it and setting an example [17].
In the last, we analyzed the influence of Lean Leadership
practices on the shop floor behavior. The results are
presented in Table.4, which show, for each lean requirement
in the shop floor employee behavior the average number of
difficulty.

Decidedly, it can be observed that behavioral on the shop
floor are largely influenced by specific Lean Leadership
practices. The findings about difficulty average number
indicate that the shop floor operators are moderately less
focusing on improvement (50.72%) and problem solving
(48.79%). Equally, the results revealed that the shop floor
operators are moderately less inciting to stop lines in case of
quality problem (52.66%). These results can be considered a
revealing consequence of large difficulty for managers to
put quality above productivity and efficiency (52.66%)
depicted in Table.3. The finding is totally agreed with
operations management researches also believe that Lean
Leadership has implications for employee outcomes [27].
Likewise, these results provide various researches
examining the link between management behavior and LM
performance and clearly assume that leadership affect
behavior of individuals in the shop floor, which in a positive
case facilitates the achievement of LM promises regarding
organizational benefits and customer satisfaction.
Consequently, it is the integration of LM practices in the
shop floor through a perfect Lean Leadership that would
have the ability to achieve multiple organizational goals and
superior result in quality of product and service [12].

4. CONCLUSION
The objective of this study was to close a gap in Lean
Manufacturing research in Morocco by analyzing the
moderation of Lean Leadership effectiveness by dimensions
of national cultural by exploring the status of Lean
Leadership practices in various multinationals located in the
country. To summarize it can be concluded that the survey
findings fit with existing theory. As shown in Table.3,
managers and supervisors are less focused in continuous
improvement projects and less performing in training the
shop floor employees. These results provide a deeper
understanding of why major organizations find
implementing and using Lean Manufacturing practices
difficult. The explanation for this finding is that Lean
Manufacturing and quality approaches require a
fundamentally different philosophy of management than the
traditional mass production approach.
Next, we have investigated the relation between Lean
Leadership practices and each of these behavioral effects, as
depicted in Table.4. This table confirms the broad impact of
leadership on the shop floor behavior. It is also a further
confirmation of various researches who argued that the
success of Lean Manufacturing depends heavily on the
topmost leaders embracing it, believing in it, and properly
applying it. Consequently, no lean behaviors will be
sustained unless they are modeled. Thus, managers must
model the lean behavior they desire if they expect it from
their shop floor employees.
