Abstract The evolution in the technology of automobiles has reached its peak. One of the most innovative features is the invention of driver less car or an autonomous car. An autonomous car controls the motion, sensor activation and action automatically without any human intervention. Such vehicles ensure high degree of safety, comfort and ease of driving. The project aims at designing a system to be used in such autonomous cars. The project is to develop an automatic headlight beam intensity switcher. Such a system will sense the beam status of opposing vehicle and switch the beam intensity of headlight. A sensor based mechanism is utilized to develop the system. The beam intensity switcher plays a very important role while driving. During night time, when two vehicles approach each other in opposite direction the high intensity headlight creates an effect called “Troxler effect”. This effect creates a temporary blindness for some seconds thus resulting in unfortunate accidents. Thus, the high beam of both the vehicles must be switched to low so as to have a comfortable driving. The use of such a device in cars can prevent accidents at night time due to driver inattentiveness and provides an ease of driving. We have used the Arduino UNO board as our micro-controller and application specific sensors. In our project we have designed a device which is a combination of software and hardware coding. The sensor used is a light intensity sensor named BH1750 which has a wide range of sensing capacity. The light sensor takes the “lux ” reading of the headlight rays from the opposing vehicle and checks for a threshold value assigned in the coding. Based on the threshold value the beam switches from high to low state and vice-versa when both the vehicles pass by each other. The same process takes place in opposite vehicle too. This device can be implanted on the front part of the car at an appropriate position and angle. Keywords: automatic, low cost, accurate, headlight beam intensity switcher, Troxler effect, sensor based mechanism and lux readings.
Study on properties of concrete with different levels of replacement of cemen...eSAT Journals
Abstract Concrete is a widely used construction material which contains four major ingredients such as coarse aggregate, fine aggregate, cement and water. The consumption of concrete is increasing every year with the number of developmental activities in infrastructure sector. The production of cement involves high energy consumption. Hence, there is a need to reduce the consumption of cement in concrete by using other alternate materials which posses cementitious properties. Fly ash is one such material which can be used as a replacement to cement in concrete. The present study aims in observing the variation of strength of different grades of concrete with different levels of fly ash replacement. The objective of the study is to re-establish the findings of earlier research done in the area of fly ash concrete. The grades of concrete selected for the study are M20, M35 and M50. The fly ash replacements considered for the study are 0%, 20%, 35% and 50% of cement by weight. The results of this study indicates that for M20 and M35 grades of concrete, there is increase in strength with 35% cement replacement by fly ash. For M50 grade of concrete, there is decrease in strength for all replacement levels selected for the study. Keywords: Concrete, Cementitious material, Fly ash.

Abstract
Today road and transport authorities around the world collectively spend large sums of money each year enhancing and maintaining their road networks. Road users in the majority of countries around the world continue to desire better and smoother roads, despite pressure on road authorities to further reduce expenditure. This pressure is brought about, because funding for road infrastructure is only one of the many priorities competing for Government funds. Pavements cannot be managed to the degree desired by decision makers, unless detailed accurate information and analysis supports the system. Road roughness data is considered one of the most important aspects of road condition information used in practice in pavement management systems.
At present in the market, we have various roughness measuring equipments starting from costliest equipment such as ARAN laser (which uses laser beam to measure the roughness) to moderately costly Bump integrator (which uses the bump counts made by the probe wheel), to cheaper equipment such as MERLIN (which uses the slope value of the wheel to calculate the roughness). In the present research work, an attempt is made to develop low cost roughness measuring equipment and to check its reliability and repeatability to minimize the calibration error. It is calibrated using Bump integrator.

A novel dual point clamper for low-rigidity plate milling with deformation co...eSAT Journals
Abstract
The surface profile accuracy plays a significant role in achieving the overall product’s functional performance, which is seriously impacted by the cutting forces, clamping forces, and residual stresses. Conventionally, many researches about deformation compensation focus on cutting forces and fixture layout and do not consider clamping forces. Actually, clamping forces, which would dynamically change along with the movements of cutting tools, are essential in precision machining process. In this paper, a novel dual-point clamper method with adaptive deformation compensation is proposed to improve the workpieces milling precision. Based on the Generalized Principle of Superposition Method, a mathematical model considering the deflection from both cutting forces and clamping forces has been estimated and compared with the traditional clamping scheme. Both 3D finite element model (FEM) based simulation experiments and experimental case studies are carried out, and their results show good agreement with each other. The deflection computation and prediction from numerical studies indicates the efficiency and correctness of the proposed approach.

Abstract In the present paper, we prove a global direct theorem for the modified Baskakovstancu operators in terms of Ditzian-Totik modulus of smoothness. Here, we have modified our operators by taking weight function of Beta operators and then generalizing it as stancu type generalized operators. We will also see that taking weight function of Beta operators will give better approximation. We study a global direct theorem using simultaneous approximation for ourstancu type generalized operator in 퐿푝 0,∞ . Here, first we estimate recurrence relation for moments and then develop some global direct results by making our stancu type generalized operators positive using differential and integral operators. In this paper, our effort is to give better global approximation for our stancu type generalized operator than the earlier integral modifications of Baskakov operators studied by various authors. Here, we will extend our results for the whole interval 0,∞ . In this paper, we will also make use of the fact that second modulus of smoothness introduced by Ditzian-Totik is equivalent to modified k-functional and 퐿푝푟[0,∞) is not contained in 퐿1푟[0,∞) for obtaining results. Here, Riesz-Thorin theorem and Leibnitz theorem is used extensively for doing simultaneous approximation. We have also used Fubini’s theorem for obtaining results.

Abstract
Mechanic studies realized on the two dimensional beams structures with swivel joints show that in statics, the vertical displacement is
continuous, but the rotation is discontinuous at the node where there is a swivel joint. Moreover, in dynamics, many authors do not
usually take into account the friction effect, modeling of these structures. We propose in this paper, a modeling of the beams structures
with swivel joints which integrates viscosity effects in dynamics. Hence this work we will present the formulation of motion equations
of such structures and the modal analysis method which is used to solve these equations.

Mitigation of harmonics using thyristor based 12 pulse voltage source pwm rec...eSAT Journals
Abstract Three-phase thyristor rectifiers have been used in industries for obtaining a variable dc voltage, but they have a problem of including large lower-order harmonics in the input currents. For high-power applications, a 12-pulse configuration is useful for reducing the harmonics, but it still includes the (12m ± 1) th (m: integer) harmonics. In order to further reduce the harmonics, this paper proposes to supply a ramp wave voltage at the input of a 12-pulse phase-controlled rectifier. Theoretical investigation to reduce harmonics is presented, and a strategy to control the regulated voltage and unity power factor at input side based on 12 pulse modulation technique. This paper discuss the impact of using 3-phase and 12-pulse rectifier circuit commonly found in unity power factor at input ac mains and regulate output voltage. The 12-pulse topology is known to be more expensive, but produce the least input current harmonics. However, the latter statement is completely true under balanced line conditions. In practice, the lines are inherently unbalanced. Hence, the question of whether the 12-pulse rectifier will indeed perform better in terms of the harmonics injected to the line is still under on-going discussions. This presents the modelling and simulation of both rectifier topologies to compare their input current and regulated output voltage harmonics. The rectifiers are modelled using the MATLAB/SIMULINK simulation model and several common cases conditions will be simulated to compare their harmonic levels. Keywords: Pulse Width Modulation (PWM), unity Power factor (UPF).
Object recognition from image using grid based color moments feature extracti...eSAT Journals
Abstract Image processing is a mechanism to convert an image into digital form and perform various operations on it, in order to get an enhanced image or to extract some useful information from it. In Image processing system, it treats images as two dimensional signals while applying number of image processing methods to them. This leads to an increasing number of generated digital images. Therefore it is required automatic systems to recognize the objects from the images. These systems may collect the number of features of a image and specification of image and consequently the different features of an object will identify the object from the image. Image processing is among rapidly growing technologies today, with its applications in various aspects of a business. Image Processing forms core research area within engineering and computer science disciplines too. Its most common and effective method is retrieve the textual features from various methods. But most of the methods do not yield the more accurate features form the image. So there is a requirement of an effective and efficient method for features extraction from the image. Moreover, images are rich in content, so some approaches are proposed based on various features derived directly from the content of the image: these are the grid-based-color-moments (GBCM) approaches. They allow users to search the desired object from image by specifying visual features (e.g., colour, texture and shape). Once the features have been defined and extracted, the retrieval becomes a task of measuring similarity between image features. In this paper, we have proposed a number of existing methods for GBCM applications. Keywords- object, grid-based-color-moments (gbcm), features, feature extraction, textual features, Image Processing, Digital form, Object Identification

Maximizing network capacity and reliable transmission in mimo cooperative net...eSAT Journals
Abstract Network capacity is an important factor to measure the performance of a network. Cooperative networking is a phenomenon which helps network to have significant gains in terms of transmission reliability and network capacity. Cooperating networking has been applied to multi-hop ad hoc networks. However, the existing works have two limitations. They support only single antenna model and three node relay scheme. The reason behind this limitation due to lack of complete understands of optimal power allocation structure Multiple Input and Multiple Output (MIMO) cooperative networks. Recently Liu et al. studied structural properties with respect to MIMO cooperative networks in presence of node power constraints. Each power allocation at source follows corresponding MIMO structure so as to ensure optimal power allocation. They establish relationship between cooperative relay and pure relay to quantify performance gain. In this paper we did experiments on this concept. Our simulations reveal that the proposed system for cooperative network is able to achieve both transmission reliability and network capacity.

Abstract In this study, for the first time, a nanoceramic Al2O3 was used as a coating material in the low heat rejection engine concept. Experiments were conducted on single cylinder, four stroke, water cooled, and direct injection diesel engine. First, the engine was tested at different load conditions without coating. Then, combustion chamber surfaces cylinder head, cylinder liner, valves, and piston crown face were coated with nanoceramic material of Al2O3 using plasma spray method. Comparative evaluation on performance and combustion characteristics using diesel, multi-blend biodiesel and its blends was studied in the ceramic coated and uncoated engines under the same running conditions. An increase in engine power, brake thermal efficiency and a decrease in specific fuel consumption were observed in the ceramic coated engine compared to that of normal engine.

Voltage collapse mitigation by reactive power compensation at the load sideeSAT Journals
Abstract Power system stability may be defined as the property of a power system that enables it to remain in a state of operating equilibrium under normal operating conditions and to regain an acceptable state of equilibrium after being subjected to a disturbance. A general and formal definition is given below. The IEEE/CIGRE Joint Task Force has proposed the following definition-“Power system stability is the ability of an electric power system, for a given initial operating condition, to regain a state of operating equilibrium after being subjected to a physical disturbance, with most system variables bounded, so that practically the entire system remains intact.” The challenge faced in the modern power system is the collapse of voltages at heavy loads at the load buses of a power system. The voltage collapse will in turn will effect the stability of the power system. In this paper a novel way of mitigating the voltage collapse by supplying the reactive power at load buses is discussed and encouraging simulation results are obtained. The method employed is as fallows. Simulation is done without SVC and STATCOM at load buses. On comparison of the results at the load buses it is seen that with SVC and STATCOM at the load buses voltage collapse is mitigated in spite of heavily loading the system. Keywords: Voltage Collapse, Reactive Power Management, Load Bus, Power System Stability.

Abstract To estimate the natural period of vibration, codes consign the empirical formula that solely relies on height of the structure. Present dissertation is carried out considering aspects such as building material, type of structure and structural dimensions. The foremost objective of the present systematic study has led to a simplified period-height equation for use in the seismic evaluation of reinforced concrete structures, taking due significance of the existence of stilt floors and shear walls. Current study also highlights the criteria that affects the period of vibration. The period of vibration which has been procured in this study represents the time period of first mode of vibration. This article comprises the seismic response of structures on different types of soil. The parameters considered for the given study are three different types of soil i.e., soft soil, medium soil and hard rock for high seismic zone and different building irregularities as per IS: 1893-2002 for 10, 15, 20 storey buildings. The analytical models for the modulus study are modeled through ETABS.V.9.2. Various parametric studies are carried out to determine the fundamental time period of the structures. These ameliorate formulas to determine the fundamental time period are developed using nonlinear regression analysis through ORIGIN pro software. The generalized equation finally obtained can be used in general form to calculate the time period of structures with open stilt floor and shear walls irrespective of soil types, seismic zone or building height. Keywords- Time period, open stilt floor, Shear walls, Irregularities in buildings, nonlinear regression

This presents the modelling and simulation of both rectifier topologies to compare their input current and regulated output voltage harmonics. The rectifiers are modelled using the MATLAB/SIMULINK simulation model and several common cases conditions will be simulated to compare their harmonic levels.

Object recognition from image using grid based color moments feature extracti...eSAT Journals
Abstract Image processing is a mechanism to convert an image into digital form and perform various operations on it, in order to get an enhanced image or to extract some useful information from it. In Image processing system, it treats images as two dimensional signals while applying number of image processing methods to them. This leads to an increasing number of generated digital images. Therefore it is required automatic systems to recognize the objects from the images. These systems may collect the number of features of a image and specification of image and consequently the different features of an object will identify the object from the image. Image processing is among rapidly growing technologies today, with its applications in various aspects of a business. Image Processing forms core research area within engineering and computer science disciplines too. Its most common and effective method is retrieve the textual features from various methods. But most of the methods do not yield the more accurate features form the image. So there is a requirement of an effective and efficient method for features extraction from the image. Moreover, images are rich in content, so some approaches are proposed based on various features derived directly from the content of the image: these are the grid-based-color-moments (GBCM) approaches. They allow users to search the desired object from image by specifying visual features (e.g., colour, texture and shape). Once the features have been defined and extracted, the retrieval becomes a task of measuring similarity between image features. In this paper, we have proposed a number of existing methods for GBCM applications. Keywords- object, grid-based-color-moments (gbcm), features, feature extraction, textual features, Image Processing, Digital form, Object Identification

Maximizing network capacity and reliable transmission in mimo cooperative net...eSAT Journals
Abstract Network capacity is an important factor to measure the performance of a network. Cooperative networking is a phenomenon which helps network to have significant gains in terms of transmission reliability and network capacity. Cooperating networking has been applied to multi-hop ad hoc networks. However, the existing works have two limitations. They support only single antenna model and three node relay scheme. The reason behind this limitation due to lack of complete understands of optimal power allocation structure Multiple Input and Multiple Output (MIMO) cooperative networks. Recently Liu et al. studied structural properties with respect to MIMO cooperative networks in presence of node power constraints. Each power allocation at source follows corresponding MIMO structure so as to ensure optimal power allocation. They establish relationship between cooperative relay and pure relay to quantify performance gain. In this paper we did experiments on this concept. Our simulations reveal that the proposed system for cooperative network is able to achieve both transmission reliability and network capacity. Keywords –Cooperative networking, MIMO, optimal power allocation, transmission reliability

a single close-loop control technique is proposed in this work which can ensure both the power control as well as a satisfactory
zero voltage switching (ZVS) in a finite control range near the operating point. A phase shift controlled series resonant inverter is
used as a power supply for an induction cooking system. Its linearized model is developed for small signal analysis and a PID
controller is designed for the proposed close-loop control and its performances are judged under various operating conditions
using MATLAB/Simulink® platform.

Voltage collapse mitigation by reactive power compensation at the load sideeSAT Journals
Abstract Power system stability may be defined as the property of a power system that enables it to remain in a state of operating equilibrium under normal operating conditions and to regain an acceptable state of equilibrium after being subjected to a disturbance. A general and formal definition is given below. The IEEE/CIGRE Joint Task Force has proposed the following definition-“Power system stability is the ability of an electric power system, for a given initial operating condition, to regain a state of operating equilibrium after being subjected to a physical disturbance, with most system variables bounded, so that practically the entire system remains intact.” The challenge faced in the modern power system is the collapse of voltages at heavy loads at the load buses of a power system. The voltage collapse will in turn will effect the stability of the power system. In this paper a novel way of mitigating the voltage collapse by supplying the reactive power at load buses is discussed and encouraging simulation results are obtained. The method employed is as fallows. Simulation is done without SVC and STATCOM at load buses. On comparison of the results at the load buses it is seen that with SVC and STATCOM at the load buses voltage collapse is mitigated in spite of heavily loading the system. Keywords: Voltage Collapse, Reactive Power Management, Load Bus, Power System Stability.

Abstract To estimate the natural period of vibration, codes consign the empirical formula that solely relies on height of the structure. Present dissertation is carried out considering aspects such as building material, type of structure and structural dimensions. The foremost objective of the present systematic study has led to a simplified period-height equation for use in the seismic evaluation of reinforced concrete structures, taking due significance of the existence of stilt floors and shear walls. Current study also highlights the criteria that affects the period of vibration. The period of vibration which has been procured in this study represents the time period of first mode of vibration. This article comprises the seismic response of structures on different types of soil. The parameters considered for the given study are three different types of soil i.e., soft soil, medium soil and hard rock for high seismic zone and different building irregularities as per IS: 1893-2002 for 10, 15, 20 storey buildings. The analytical models for the modulus study are modeled through ETABS.V.9.2. Various parametric studies are carried out to determine the fundamental time period of the structures. These ameliorate formulas to determine the fundamental time period are developed using nonlinear regression analysis through ORIGIN pro software. The generalized equation finally obtained can be used in general form to calculate the time period of structures with open stilt floor and shear walls irrespective of soil types, seismic zone or building height. Keywords- Time period, open stilt floor, Shear walls, Irregularities in buildings, nonlinear regression

Whether due to illness or injury, organ failure is a worldwide problem and its only treatment is organ transplantation or tissue replacement. Although it’s the only solution in these cases, organs demand greatly surpasses the supply. Organs are usually obtained from people who recently have died (up to 24 hours past the cessation of heartbeat) or from people who are clinically brain dead and their body functions are maintained artificially, nevertheless living organ donation is becoming more frequent [1]. The increase of the organ demand has been raising ethical concerns, since this can result in offers or incentives for donation, profit on donated human organs or even exploitation of the disadvantaged. In the developed world most countries have a legal system that oversee organ transplantation, however in poorer countries a black market has been arising, enabling those who can afford to buy organs, exploiting those who are desperate enough to sell them
3D Bio-Printing; Becoming Economically FeasibleJeffrey Funk
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze the increasing economic feasibility of bio-printing. Due to a lack of available kidney and other organ donors for organ transplants, 3D printing has emerged as an important alternative for many people. Bioprinting is done by using a computer model of an individual’s body to generate a data set for an organ that can be printed with a 3D printer and grown in a bio-reactor. The falling cost of materials and 3D printers is improving their economic feasibility.
Fourth revolution through 3 d technologyM S Siddiqui
The World Economic Forum (WEF) revealed that the 3D printing technology can change the world in ten ways. It can- (a) enable the blind and visually impaired people the chance to see, (b) create body plants e.g. bone implants to limbs, (c) produce lightweight casts for broken bones, (d) ensure faster medical progress, (e) make stronger and safer vehicles, (f) ensure better and cleaner factories by reducing the number of factory workers and waste produced by the industry, (g) ensure faster design and innovation, (h) promise less pollution from shipping, (i) guarantee better education in science, technology, engineering and mathematics as using printers the schools can make subjects more engaging, and (j) enable to make miniaturized devices to guarantee targeted medical treatment. Bangladesh may frame the rule and encourage the use of 3D technology without any legal and procedural intervention.
Increasing the efficacy of drugs and at the same time reducing the chances of adverse reaction should be the aim of drug development, which can be achieved by using 3D printing to fabricate personalized medications
Drugs with narrow therapeutic index can easily be prepared using 3D printing; and, by knowing the patient’s pharmacogenetic profile and other characteristics like age, race etc., optimal dosage can be given to the patient.
3D printing technology is a valuable and potential tool for the pharmaceutical sector, leading to personalized medicine focused on the patients’ needs. It offers numerous advantages, such as increasing the cost efficiency and the manufacturing speed. 3D printing has revolutionized the way in which manufacturing is done. It improves the design manufacturing and reduces lead time and tooling cost for new products.

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.

Laboratory investigation of expansive soil stabilized with natural inorganic ...eSAT Journals
Abstract
Soil stabilization has proven to be one of the oldest techniques to improve the soil properties. Literature review conducted revealed
that uses of natural inorganic stabilizers are found to be one of the best options for soil stabilization. In this regard an attempt has
been made to evaluate the influence of RBI-81 stabilizer on properties of black cotton soil through laboratory investigations. Black
cotton soil with varying percentages of RBI-81 viz., 0, 0.5, 1, 1.5, 2, and 2.5 percent were studied for moisture density relationships
and strength behaviour of soils. Also the effect of curing period was evaluated as literature review clearly emphasized the strength
gain of soils stabilized with RBI-81 over a period of time. The results obtained shows that the unconfined compressive strength of
specimens treated with RBI-81 increased approximately by 250% for a curing period of 28 days as compared to virgin soil. Further
the CBR value improved approximately by 400%. The studies indicated an increasing trend for soil strength behaviour with
increasing percentage of RBI-81 suggesting its potential applications in soil stabilization.
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
Abstract
Increase in traffic along with heavier magnitude of wheel loads cause rapid deterioration in pavements. There is a need to improve
density, strength of soil subgrade and other pavement layers. In this study an attempt is made to improve the properties of locally
available loamy soil using twin approaches viz., i) increasing the compaction of soil and ii) treating the soil with chemical stabilizer.
Laboratory studies are carried out on both untreated and treated soil samples compacted by different compaction efforts. Studies
show that increase in compaction effort results in increase in density of soil. However in soil treated with chemical stabilizer, rate of
increase in density is not significant. The soil treated with chemical stabilizer exhibits improvement in both strength and performance
properties.

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.

Effect of variation of plastic hinge length on the results of non linear anal...eSAT Journals
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.

Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

1. INTRODUCTION
There are many predictions, regarding the future [1], [2],
[3],[4],[10], [12] and all may seem like science fiction, but
as the great scientist Arthur C Clarke said: "Any sufficiently
advanced technology is indistinguishable from magic." -
Profiles of The Future, 1961 (Clarke's third law).
The publication of the National Intelligence Council „Global
Trends 2030 Alternative Worlds“[4] deals with 4
Megatrends:
Individual empowerment will accelerate owing to
poverty reduction, growth of the global middle class,
greater educational attainment, widespread use of
new communications and manufacturing
technologies, and health-care advances.
Diffusion of Power: There will not be any hegemonic
power. Power will shift to networks and coalitions in
a multipolar world.
The demographic arc of instability will narrow.
Economic growth might decline in “aging” countries.
Sixty percent of the world’s population will live in
urbanized areas; migration will increase [1].
Demand for these resources will grow substantially
owing to an increase in the global population.
Tackling problems pertaining to one commodity will
be linked to supply and demand for the others [2].
2. OCCAM'S RAZOR
Occam's razor is a problem-solving principle devised by
William of Ockham (c. 1287–1347), who was an English
Franciscan friar and scholastic philosopher and theologian.
The principle states that among competing hypotheses, the
one with the fewest assumptions should be selected.
In science, Occam's razor is used as a heuristic (discovery
tool) to guide scientists in the development of theoretical
models rather than as an arbiter between published models.
In the scientific method, Occam's razor is not considered an
irrefutable principle of logic or a scientific result; the
preference for simplicity in the scientific method is based on
the falsifiability criterion.
For each accepted explanation of a phenomenon, there is
always an infinite number of possible and more complex
alternatives.
3 KEY TRENDS FOR THE ECONOMY AND
MANAGEMENT UNTIL 2020
Using Occam's razor, we can identify 3 Key Trends:
3.1 3D
Development of the society will be affected significantly by
the 3D printing. It will mean the extreme decentralization of
production and also manufacturing in the customer’s
location.

3D printing is a process of production of three-dimensional
objects from suitable material through specific devices.
Printing successively layer by layer is under computer’s
control.
3D printing technology beginnings appeared in the second
half of the 20th century. In March 1986, Charles Hull
patented a technology called stereolithography – a method
that uses ultraviolet laser beam. Surface of polymer liquid,
wherein it draws the individual layers of the object. Then,
the layer is cured by UV light. At the end of 90’s, Charles
Hull started the company 3D Systems and created the first
device that was able to print three-dimensional object – SLA
device, or "stereolithography apparatus".
The SLA models have served to the public and became the
basis for the development of today's 3D printers. After 2003,
when the development of technology accelerated due to
expiration of some patents, there are new technologies,
terminology and materials, but for clarity they are more
often called simply "3D printing". The material is applied
from the nozzles on a moving platform. Patterned layers
create a 3D object. Printing technology of physical 3D
objects from digital data is called "additive manufacturing".
Areas of use of 3D printing technology:
Medicine and Research
Food Industry
Consumer products
Design, architecture, electrical engineering,
mechanical engineering
Education
Automotive and aerospace industry
Arms industry
3.1.1 Medicine and Research
Prosthetics and assistive devices
In 2013, an Englishman Paul McCarthy printed to his
son a robotic prosthesis at home 3D printer. To do
this, a guide that he found on the internet was enough
for him. His son was born without fingers on one
hand, and thanks to printed mechanical prosthesis
could grasp various objects for the first time.
This has dramatically improved his quality of life.
Price of such produced prostheses McCarthy
enumerated for a couple dollars.
Hearing Aids
According to estimations by the British analyst Phil
Reeves currently it is over 10 million printed hearing
aids in the world.
Burns and skin injuries
In the treatment of skin injuries with 3D printing the
situation is still in the stages of development and
testing. Currently, scientists are investigating the
possibility of combining technology of the 3D
printing and technology of growing stem cells. It is
intended to use it also in medical cosmetics.
Fractures and bone destruction
In mid-2013 it was possible to replace 75% of the US
patient's skull thanks to a special 3D compensation.
Special polymer implant titled Osteofab was
designed to promote the growth of tissues and for
faster recovery of the patient.
Human organs
In connection with printing organs the mostly spoken
is the company Organovo which has developed the
technology to print small samples of human liver
tissue. Samples were able to survive a few days.
However it is still possible to print the organs only in
shape, but not functionally correct.
3.1.2 Food Industry
Information about 3D printing of food spread in the middle
of this year, mainly thanks to the American space agency
NASA. The agency thumbed-up for a research program to
print food in space.
The idea that astronauts in space will print pizza is tempting,
but inaccurate.
The NASA Program is based on the replication
characteristics of food. It is about to allow a 3D printer
printing from such materials, which will contain enough
calories and organic molecules as similar as possible to
those in the classic food.
According to the experts the cartridge for printing of food
would include, for example, powder from insects, algae or
milk. Each cartridge would fit to some taste and at the same
time would be nutritionally balanced. The project of the
food printer is still in the development stage.
The 3D printing is already used in the food industry, but
only for special techniques - it is possible to print from
material such as chocolate. It is melted by heat in printer’s
nozzles and cooled again to harden, which is ideal for
printing 3D models. In the US there are two architects from
San Francisco printing 3D objects from sugar. Sugar designs
pieces are printed on common 3D printer with customization
and to harden sugar alcohol is used.
In Barcelona, there is a project that aims to print dishes from
dough, paste or from solidifying liquids. These have the
perfect consistency for filling food cartridges for printers
and it is theoretically possible to prepare from them more
complicated, but real food.
3.1.3 Consumer Products
Consumer goods will be changed from prefabricated to
customized goods.
Here arises the opportunity to design and print your own
products for daily consumption. Current experiments are
with materials such as:
White plastic (thermoplastic material ABS
(acrylonitrile butadiene styrene)).

Ceramics and glazing (ceramic composition of
aluminum oxide and silicon oxide, the completed
product is after remove from the printer glazing and
then hardened, sintered, in fire as well as classic
ceramics).
Wood (a mixture containing about one third of the
wood fibers (directly from wood or wood waste from
sawing machines dust) and two thirds of PLA
material (polylactic acid).
Metal (electrical components).
Textiles (materials for printing on thread and fabrics.
There has been already lingerie printed from the latex-
rubber polymers enriched by cotton fibers. Other materials
enriched by viscose are also tested).
3.2 Phenomenon RFID
Forecast can stem from a wide-scale monitoring of the RFID
technology [10], [11]. Forecast created with exponential
regression until 2021 is shown in Table 1.

More than 260 000 RFID readers will be used in 2013,
which will be deployed in 45 000 locations over Europe. In
the same year, RFID readers will process 4.7 billion tags.
These numbers will grow significantly until 2021 when
more than 5 million readers in 394 000 locations are
expected to process more than 75 billion tags (see Graphs 1-
3).
Graphs 3-5 are created using exponential regression.
Exponential regression has 2 parametres generally:
𝑦𝑖 = 𝑏0 𝑒 𝑥 𝑖 𝑏1 (1.1)
ln 𝑦𝑖 = ln 𝑏0 𝑒 𝑥 𝑖 𝑏1 (1.2)
ln 𝑦𝑖 = ln 𝑏0 + ln 𝑒 𝑥 𝑖 𝑏1 (1.3)
ln 𝑦𝑖 = ln 𝑏0 + 𝑥𝑖 𝑏1 (1.4)
where e = 2,71828... is the basis of natural logarithm.
The formula of the exponential regression for chart on Fig. 4
is:
𝑦 = 36,396 𝑒0,3687 𝑥
(1.5)
where x represents years on the time axis.

The values in the table 3 represent only a small percentage
of the total number of objects which can be tagged. The
forecast based on the prediction of the BRIDGE project says
that only 2% of all FMCG (fast moving consumer goods)
will be tagged in 2013.
Further, it presumes that roughly 25% of non-food and 5%
of food retail items will be tagged by 2021. If the
technology development is confirmed in following years,
the price of RFID tags could drop below one eurocent [12]
which could lead to a dramatic rise in the number of tags –
especially the number of tags in the food-processing
industry could shoot up to hundreds of billions.
The RFID technology represents the most important
economic factor of the near future. The price of RFID
passive tags will further decrease thanks to mass production
and technology development, it is predicted that between
2012 and 2013 the price of one tag will drop to 5 USD cents
and in 2015 these could be made under the price of 3 cents.
The price development is shown on graph 4.
Chart 4: Development of passive RFID tags price. Blue
points – historic prices; full line – compensation and
exponential extrapolation. Source: author [11].
In the future, the price of RFID will be only fractions of
cents with the size smaller than a pollen grain. This, in
connection with distributed artificial intelligence, it will
enable:
fix every human to the megaintegrated computer
system and monitor his health, social position and
political views and the computer feudal monarchy
will be established effective central planning of the
whole world economy
electronic communication with pets, later also with
mammals, cetaceans and vegetation, i.e. whole
biosphere which will become a new segment of
economy and after change of legislation will be
integrated into the political and economic system.
3.3. Business Intelligence
According to recent studies and analysis, the global market
for Business Intelligence (BI) software and services is likely
to double over the 4 year period between 2012 and 2016,
reaching approximately $143 billion in total.
Based on the data from the official annual reports of the 4
largest BI vendors – Microsoft, IBM, Oracle and SAP -
from 1992 to 2013, we can assess their performances over
the last 20 years, and then estimate what trend their annual
revenues are most likely going to follow until 2020.
Microsoft Corporation has been doing fairly well since
1992, following almost linear trend with slightly steeper
growth during the period 2007-2009. This stable growth
might continue with the same trend, reaching annual
revenue worth $100 billion by 2020.

International Business Machines (IBM). Thanks to much
longer market activity (IBM mark founded in 1924), the
annual revenues of IBM started at $65 billion for the year
1992, then growing more gradually than in case of the other
vendors. Despite its many deviations, the progress is almost
linear, and so is the forecasted trend. With all aspects going
well, IBM’s revenue for the year 2020 could be worth $120
billion, increasing the current one by $20 billion (the same
as Microsoft).

Oracle Corporation. In case of Oracle, the youngest one of
these 4 leaders, we can clearly see a bit more dynamic
progress. Starting with linearity, the trend of Oracle’s annual
revenues changed to something similar to hyperbolic tangent
in 2001. A mild decrease from 2001 has been followed by
an almost exponential growth, slowing down again in 2011.
To be optimistic enough, we can conclude that the trend is
going to be linear again in the following period, possibly
exceeding $40 billion of annual revenue in 2020.

SAP, the only European leader of BI platforms production,
had considerably lower revenues than its other competitors.
However, it possesses ca. quarter of the ERP and CRM
software market, which probably reflected in a steeper
growth from 2009 on. Based on these facts and overall data,
the trend is most likely to remain linear and can lead to 2020
annual revenue worth €20 billion (~$28 billion).
Chart -8: SAP annual revenues 1992-2020. Source: author.

All this facts shows, that the applications of BI will be
growing and transformation of the BI to the general
intelligence may be predicted. In conclusion, after summary
of the above results, it becomes clear that artificial
intelligence will not be „all-knowing“ and „all-wise“, but
only „cleverer to a limited extent“ than a human being.
4. CONCLUSION
More than 10 000 years ago the 3 Key trends were: fire,
processing of Metals and developing of the agriculture.
Today is the situation different: the Key Trends will be 3D
printing, RFID everywhere and Business Intelligence.
For some time now, the General Intelligence community has
been trying to imitate intelligent behavior with computer
programs. This is not an easy task because a computer
program must be able to do many different things in order to
be called intelligent. Instead of looking at a general
definition of General (Artificial) Intelligence, one can also
restrict oneself to the definition of artificially intelligent
systems.
There are many definitions around, but most of them can be
classified into the following four categories:
Systems that think like humans
Systems that act like humans
Systems that think rationally
Systems that act rationally.
The Forecast for the Future will include:
Self-learning management systems, MIS controlled by voice
and ideas, are the wave of the future.
With the advent of these technologies, which will be
available on the market, MIS will get a whole new
dimension. The system cannot only learn many things of
one’s own accord, it can also execute them, and work
closely with the wearer mind maps and react to them. It will
also be able to respond to spoken words. Writing queries for
this system will be completely replaced by this.

Year 2020 could look as follows:
Voice as the main controller of all systems
MIS will use extensively systems working with the
human mind – with feelings
Self-learning systems will handle unknown data
arbitrarily without any pattern on the basis of
matching
A common perception of augmented reality
3D holographic display
Devices will perceive the space around us
Devices thin as paper
Display area anywhere, anytime
Top level wireless online communication
99% of the information will be stored in the cloud
IBM achieved turnover of 120 billion of dollars
Microsoft reaches a turnover of 140 billion of dollars
SAS Instutute turnover reaches 6 billion of dollars
Czech companies offering MIS together reach a
turnover more than 100 million of dollars
New Cyberspace Managers in the 2020
Taking into consideration the aforementioned information, it
becomes obvious that this development will lead to new
managerial positions in the future. Let us briefly introduce
some that are likely to appear:
The Identity Manager will operate in the area of data
protection and related legal restrictions. It will be
necessary to identify, whether the business part ner is
a human being, a robot or a segment of the biosphere.
A new scientific discipline related to identity will be
developed.
The Chaos Manager: new inventions like Internet of
Things will complicate the whole system. Special
programs like neural or genetic software will be
essential to specify new gaps in the market.
E-government manager and Technostress manager
and many others…
The future mega-integrated single computer system will be
reflected in the political sphere of the next decades by a
computer feudal monarchy controlling the entire movement
of the society through mobile telephony, RFID and other
sophisticated segments of the technosphere.
