Design and analysis of Low-power, area efficient and high speed analogue-to-digital converters are pushing toward the use of dynamic comparators, which is used to maximize speed and power efficiency. In the existing design, an analysis on the delay of the dynamic comparators will be presented and analytical expressions are derived. From the analytical expressions, designers can obtain an intuition about the main contributors to the comparator delay and fully explore the trade-offs in dynamic comparator design. Based on the presented analysis, a new dynamic comparator is proposed; where the circuit of a conventional double tail comparator is modified for low-power and fast operation where supply voltages down to 1.2V. Without complicating the design and by adding few transistors, the positive feedback during the regeneration is strengthened, which results in remarkably reduced delay time. This paper presents a CMOS comparator that reduces the overall propagation delay and hence provides higher speed. The design is simulated in 0.18μm CMOS Technology using Tanner EDA Tools. CMOS Comparator shows that the overall propagation delay of the comparator, TPD, is 1.4872e-9 seconds, with a 1.0 V supply voltage.
The paper presents an adaptive three dimensional discrete cosine transform based cube selection algorithm which finds the optimal cube for 3D-DCT based compression technique by analysing the motion content of the video sequence. The proposed algorithm will adaptively choose the cube size in relation to the motion level of video sequence. The strength of the algorithm can be examined by performing Rate Vs distortion comparison with different motion level sequences. Peak signal to noise Ratio has been taken as a measure of distortion. Without any motion compensation technique, the proposed algorithm adaptively selects the cube size relative to the motion content of video sequence gives better performance in terms of reduction in the data rate and improves the encoding process.
An electrical device such as transformer less hybrid series active filter is used to improve the power quality in single-phase systems with crucial loads. In this paper we are mostly going through energy management as well as power quality problems in the electric transportation. We also think about improving electric load connection to the grid. To overcome the drawbacks of the current harmonic distortions we implemented control strategy. This implementation is very crucial to avoid damages in sensitive loads from voltage disturbances, sags and swells due to the power system which is considerations in industrial implementation. This implementation on polyvalent hybrid topology will give permission to harmonic isolations as well as the compensation can absorb auxiliary power to grid. We are getting gains and delays for real time controller stability. This implementation is based on 2-kVA laboratory prototype and shows effectiveness of proposed implemented topology.

Many-Objective Performance Enhancement in Computing ClustersTarik Reza Toha
In a heterogeneous computing cluster, cluster objectives are conflicting to each other. Selecting a right combination of machines is necessary to enhance cluster performance, and to optimize all the cluster objectives. In this paper, we perform empirical performance analyses of a real cluster with our year-long collected data, formulate a new many-objective optimization problem for clusters, and integrate a greedy approach with the existing NSGA-III algorithm to solve this problem.

Presentation of Eco-efficient Cloud Computing Framework for Higher Learning I...rodrickmero
Tanzanian Higher Learning Institutions (HLIs) are facing challenges in providing the necessary Information Technology (IT) support for education, research and development activities. Currently, HLIs use traditional computing (TC) which has proven to be uneconomical in terms of maintenance, software purchase costs, huge power consumption and staffing.
Cloud computing (CC) is the way forward for HLIs in solving the computing challenges. However, the HLIs policies regarding security of critical data in CC environment prevent adoption of CC services from existing vendors. The reliable and secure way is to establish and operate CC data centers dedicated to HLIs critical data and services. Owning and operating the traditional data centers is a challenge to HLIs because it consumes huge amounts of power. Tanzania like other developing countries has a low level of electrification, while the need for electric power consumption is increasing year after year. The need to consider energy efficient approaches in data center operation is very important for reducing both the operation costs and carbon footprint to the environment.
Therefore, this thesis presents the eco-efficient cloud computing framework that integrates renewable and non-renewable power sources, and free cooling in reducing carbon emission and power consumption in HLIT cloud data centers.
To develop the framework, we conducted a study in Tanzania HLIs to explore the current situation and cloud computing requirements. Interview, Observation, and document review were data collection method used by the study. After analysis of the results, we defined guidelines for developing CC building blocks. We used CloudSim tool kit and Netbin IDE to develop and to simulate eco-efficient framework.
At the end, eco-efficient framework has shown improvement on power consumption, efficiency and carbon emission. Therefore, eco-efficient approaches give HLIs of Tanzania sustainable solution to their computing needs by significantly reducing operating costs. Moreover, it ensures environment protection for the benefit of current and future generations.

Machine Learning Approach to Geometry Prediction in Cold Spray Additive Manuf...Daiki Ikeuchi
Cold spray additive manufacturing is an emerging technology that offers unique advantages including high production rate, unlimited product size and the ability to process oxygen-sensitive materials. However, cold spray additive manufacturing
suffers from low surface quality and dimensional accuracy which prevent its integration into commercial manufacturing systems. These problems originate from the poor understanding of complex relationship between process parameters and
deposit geometry. This knowledge gap motivated the development of an accurate predictive model for the geometry of a cold spray deposit profile to overcome the problems. Recently, a machine learning approach has gained interest in developing the predictive model of such complex additive manufacturing process due to its superior nonlinear mapping capability as seen in other manufacturing applications.
Therefore, the aim of the present study was to integrate a machine learning approach into the geometry prediction of cold spray additive manufacturing. The findings can contribute to the optimization of the process for shorter production time and the
development of build strategy for better as-fabricated surface and dimensional quality control. The approach in this study is also applicable in other deposition-based additive manufacturing technologies such as Wire Arc Additive Manufacturing and Laser Cladding.

Wireless sensor networks (WSNs) are used in many data-intensive applications. Although, it faces the problem to send all the data sensed by the sensor nodes to the base station within an application’s lifetime due to the limited power supplies. Several mobile nodes like data mules, robotics and mobile base station were used for minimizing power utilization. In this paper, several mobile nodes are studied and the low-priced throwaway mobile relays have been projected which reduce the energy utilization of those WSNs. This proposed work has two main aspects which differ from previous work. First, the mobile nodes are implemented in the low-priced mobile sensor platforms. Second, in the entire optimization framework, the power for both wireless transmission and mobility are reduced. The proposed Centralized Algorithm and Distributed Algorithm used in three stages, in first stage, a most favourable direction-finding tree is computed in which no nodes can move. In second stage, the topology of the routing tree is enhanced by adding new nodes. Finally, the nodes are relocated to get better the routing tree without altering the arrangement of that topology.
The innovative composite materials such as Graphite, Carbon, Kevlar and Glass with suitable resins are widely used because of their high specific strength (strength/density) and high specific modulus (modulus/density). Carbon fibres are among the most popular reinforcement additives for polymer based composites, to be used in all those applications where very excellent mechanical performances are compulsory. The technology of modern composite materials provides outstanding mechanical results to finished parts whose overall behaviour can vastly exceed many metallic alloys, even the most sophisticated. Advanced composite materials seem ideally suited for long, power driver shaft (propeller shaft) applications. Their elastic properties can be tailored to increase the torque they can carry as well as the rotational speed at which they operate. The drive shafts are used in automotive, aircraft and aerospace applications. The automotive industry is exploiting composite material technology for structural components construction in order to obtain the reduction of the weight without decrease in vehicle quality and reliability. It is known that energy conservation is one of the most important objectives in vehicle design and reduction of weight is one of the most effective measures to obtain this result. Actually, there is almost a direct proportionality between the weight of a vehicle and its fuel consumption, particularly in city driving.
In this paper, an innovative design of a wireless battery charger for portable electronic devices is proposed. The wireless power transfer is implemented through the magnetic coupling between a power transmitter, which is connected to the grid, and a power receiver, which is integrated inside the load device. An innovative receiver architecture which heavily Improve the power conversion efficiency is presented. A laboratory prototype of the proposed wireless battery charger has been realized and tested to evaluate system performances. Over the entire range of operating conditions the receiver efficiency lies within the 96.5% to99.9% range.
Montgomery multiplication is an efficient method for implementation on general purpose computers and embedded microprocessors. It is the basic operation used in modular exponentiation which is required in the RSA public key cryptosystems. The algorithm uses simple divisions by a power of two instead of divisions by M which are used in a conventional modular operation and its implementation based on a fixed precision of the operands. In order to reduce the computation time by Radix-2 and Radix-4 algorithm and also to overcome the variable precision multiplication features although the number of partial product was reduced. The complexity of control and computational logic increased substantially at the same time. The approach was able to process an n-bit precision multiplication in approximately n clock cycles to simulate by Xilinx 12.3 tool using VHDL language.

The utilization of PC in Design Analysis and advancement procedure, which is for the most part iterative in nature, decreases the dreary occupation and expands the accuracy. This extend includes one such model of wheel, which is as indicated by the determination given by the Japanese Industrial Standards. The wheel edge has been broke down for two conditions. Bowing continuance test, Radial perseverance test, In Radial continuance test, taking after three conditions have been dissected. The venture is gone for making the model of the wheel edge utilizing PRO-E Software.

Mobile Adhoc Network contains mobile nodes which are deployed randomly in the network. These mobile nodes should cooperate each other for successful communication. But due to the frequent changes in network topology, the infrastructure for communication is not available and also presence of some malicious nodes cause attacks in the networks routing path. Hence, security is the major concern in this type of network. Certificate revocation mechanism based on Weighted Voting Game (CR-WVG) approach was introduced in which malicious nodes were identified based on the voting mechanism with respect to weights and quota of each node. However, security in routing paths was still a problem in this approach. To overcome this security issue, Certificate revocation based on weighted voting game and Secure Way Routing protocol (CR-WVG-SWR) is developed in which certificate from Certificate Authority (CA), shortest route discovered and data packets are encrypted using various encryption algorithms. Thus the performance of CR-WVG-SWR scheme is improved and compared with CR-WVG in terms of false revocation, revocation of malicious nodes, accuracy ration of revocation and normalized time to revocation.
In this paper the brushless DC shunt motor is implied for speed control as well as direction control. The DC motor can easily change the direction by changing its polarity by manually. And speed control can be achieved by various methods in dc motor. The main scope is to run the dc motor in both forward and reverse direction at the same time to control the speed of the motor for required rpm. Here the dc motor is run by using MOSFET (Metal Oxide Semiconductor Field Effect Transistor). Based on the ON/OFF condition of MOSFET the motor runs at forward or reverse direction. Using the IC PIC 16F877A, the program is written in microcontroller language to ON, OFF, motor forward and reverse conditions. Based on the input is given to the motor the driver circuit runs the motor in required direction with required speed. We can implement this project wherever the speed control (constant speed) is required. For reducing the manual operation of changing the switch to run the motor, our project reduce the manual mistakes, also avoid the short circuit if in case it will happen.
Brake innovation is much the same as suspension and fuel framework innovation has made considerable progress lately. The Automobile slowing mechanisms typically utilize brake plates, which are combined with composite natural brake cushions. These sorts of materials are reasonable for use in slowing mechanisms with direct loads, yet vehicle producers are arranged to outline vehicles with all the more braking force. A background marked by high working expenses for on - parkway vehicles and for airplanes has supported outlines for weight lessening with long administration of slowing mechanisms. Upgrading of the stopping mechanism by swap of lighter material like aluminium and carbon composite brakes fundamentally have been in charge of brake circles, which are being utilized as a part of air ships and equation one dashing autos and bike bicycles .The necessities of the materials are light weight, high quality, scraped spot resistance and consumption resistance. Composite materials give such special blend of properties. In this review the substitute materials for vehicle brake circle applications with unique thought to Aluminium and Boron carbide Metal Matrix Composites .The mechanical properties were resolved according to ASTM principles and looked at the outcomes. The wear and grating conduct was resolved utilizing pin on circle device.
Jet pumps have been widely used in many applications such as water desalination, steam turbine power generation, refrigeration systems, and chemical plants. The advantage of jet pump system lies in its extremely reliable and stable operation due to the complete absence of moving parts. The performance depends on a number of factors, However among which the flow channel configuration. To obtain this better performance at different operating conditions, area ratio of the jet pump is varied. In this study, a new diffuser based on constant rate momentum change method jet pump theory is written to analyse performance of the proposed jet pump. The model based on the axis-symmetric representation of the experimental jet pump is created using Computational fluid dynamics. The analysis includes effects of pressure and the effects of velocity in the mixing chamber and in the diffuser. The simulated performance of conventional and modified jet pumps are compared. The effects of operating parameters of constant rate momentum change jet pump and conventional jet pump on entrainment ratio are studied.
Permanent Magnet DC motors find wide applications in orthopaedic surgical systems. Conventional PI controller based chopper drive is being employed in these motor drives.

The simulated results have been validated using a low cost PIC microcontroller based experimental setup. The comparative study demonstrates that the proposed system has an edge over the conventional drive systems.
In this paper, a control strategy for power flow management of a grid-connected hybrid photovoltaic (PV)–wind battery-based system with an efficient multi-input transformer coupled bidirectional dc–dc converter is presented. The proposed system aims to satisfy the load demand, manage the power flow from different sources, inject the surplus power into the grid, and charge the battery from the grid as and when required. A transformer-coupled boost half-bridge converter is used to harness power from wind, while a bidirectional buck– boost converter is used to harness power from PV along with battery charging/discharging control. A single-phase full-bridge bidirectional converter is used for feeding ac loads and interaction with the grid. The proposed converter architecture has reduced number of power conversion stages with less component count and reduced losses compared with existing grid-connected hybrid systems. This improves the efficiency and the reliability of the system. Simulation results obtained using MATLAB/Simulink show the performance of the proposed control strategy for power flow management under various modes of operation. The effectiveness of the topology of the proposed control strategy are validated through detailed experimental studies to demonstrate the capability of the system operation in different modes.

This improves the efficiency and the reliability of the system. Simulation results obtained using MATLAB/Simulink show the performance of the proposed control strategy for power flow management under various modes of operation. The effectiveness of the topology of the proposed control strategy are validated through detailed experimental studies to demonstrate the capability of the system operation in different modes.
Initially linear dataset is formed for capable recovery of data from a massive record. Before undergoing the process of data sighting feature reduction route is implemented. This reduces the dimensionality and increases the space of data cargo space. Hence the map reduce is processed for the next step in knowledge discovering process to remove unwanted and irrelevant data from the database. The Support Vector Machine is one of the classifications technique is used. This overcome the problem of k Means disadvantage, it does not support effectively for both linear and nonlinear format of data. Map Reduce method to add privacy to a huge database can be obtained by adding dual authentication technique which ensures the privacy of the user without over heading the process. This overcomes the overlapping issue caused by the k means algorithm and it also reduces the issue of finding the distance between the record and cluster.
This paper describes the case study of 500 kV and 750 kV GIS in India. The variations of VFTO magnitudes at different points in 500 kV and 750 kV GIS during different switching operations have been calculated and compared by using Mat lab/Simulink. The problem is the voltage magnifications due to reflections of fast switching and lightning surges at various junctions within the Gas Insulated substations (GIS). Thereby over voltages in GIS are more important than air-insulated substation. GIS have different specifications in proportion to air-insulated substations. Transformer failures related to lightning and switching are often reported. There are methods to suppress the stresses created by lightning and switching in the GIS. Due to the opening or closing of circuit breakers and disconnect switches in Gas Insulated Substations (GIS), especially in the pumped storage power stations, Very Fast Transient Over-voltages (VFTO) are generated. In this paper the effective factors on the level of VFTO is investigated and the beneficial approaches for the industry to find the optimum approaches for VFT mitigation is presented. These factors are include residual charges, resistance, spark resistance and entrance capacitance of transformer. This paper presents feasible methods for mitigation of the overvoltage magnitude. The advantages of the proposed methods are their simplicity and low cost for implantation along with producing minimal changes in the installed GIS in India.
Cloud computing has been envisioned as the de-facto solution to the rising storage costs of IT Enterprises. With the high costs of data storage devices as well as the rapid rate at which data is being generated it proves costly for enterprises or individual users to frequently update their hardware. Apart from reduction in storage costs data outsourcing to the cloud also helps in reducing the maintenance. Cloud storage moves the user’s data to large data centres, which are remotely located, on which user does not have any control. However, this unique feature of the cloud poses many new security challenges which need to be clearly understood and resolved. One of the important concerns that need to be addressed is to assure the customer of the integrity i.e. correctness of his data in the cloud. As the data is physically not accessible to the user the cloud should provide a way for the user to check if the integrity of his data is maintained or is compromised. In this paper we provide a scheme which gives a proof of data integrity in the cloud which the customer can employ to check the correctness of his data in the cloud. This proof can be agreed upon by both the cloud and the customer and can be incorporated in the Service level agreement (SLA). This scheme ensures that the storage at the client side is minimal which will be beneficial for thin clients.
Content services such as content filtering and transcoding adapt contents to meet system requirements, display capacities, or user preferences. Data security in such a framework is an important problem and crucial for many Web applications. An approach that addresses data integrity and confidentiality in content adaptation and caching by intermediaries. It permits multiple intermediaries to simultaneously perform content services on different portions of the data. Protocol supports decentralized proxy and key management and flexible delegation of services. Experimental results show that approach is efficient and minimizes the amount of data transmitted across the network.
Wireless sensor networks can provide low cost solution accompanied with limited storage, computational capability and power for verity of real-world problems and become essential factor when sensor nodes are arbitrarily deployed in a hostile environment. The cluster head selection technique is also one of the good approaches to reduce energy consumption in wireless sensor networks. The lifetime of wireless sensor networks is extended by using the uniform cluster head selection and balancing the network loading among the clusters. We have reviewed various energy efficient schemes apply in WSNs of which we concentrated on selection of cluster head approach and proposed an new method called Sleep Scheduling Routing with in clusters for Energy Efficient [SSREE]in which some nodes in clusters are usually put to sleep to conserve energy, and this helps to prolong the network lifetime. EASSR selects a node as a cluster head if its residual energy is more than system average energy and have less energy consumption rate in previous round. Then, an Performance analysis and compared statistic results of SSREE shows of the significant improvement over existing protocol LEACH, SEP and M-GEAR protocol in terms of lifetime of network and data units gathered at BS.
An Espresso – coffee machine supplies water whose temperature must be confined within a narrow range in different operating conditions. This requires an accurate design of the components in the system level. In this paper we design a single boiler system with a heat exchanger, analyse its performance and optimize the results to be compared with the popular working model of twin boiler system. In order to save the energy utilized by the twin boiler Espresso coffee machine. The main area of concern was the boiler involved in the coffee machine and the amount of energy it utilizes and also considering the quality of the output, which is a very well brewed coffee.
Unit commitment has been solved with many techniques viz., genetic algorithms evolution ary programming, simulated annealing, optimization and tab along with the combination of dynamic programming. This paper proposes Particle swarm Optimization combined with Lagrange Relaxation method (LR) for solving Unit Commitment (UC). The results from the test samples are compared with those obtained by Particle swarm optimization for solving unit commitment, Genetic algorithm and LR. The shortcoming of branch-and-bound is the exponential growth in the execution time with the size of UC problem. The integer and mixed integer methods adopt linear programming technique to solve and check for an integer solution. These methods have only been applied to small UC problems and have required major assumptions which limit the solution space. Lagrange relaxation for UC problem was superior to dynamic programming due to its faster computational time. However, it suffers from numerical convergence and solution quality problems. Furthermore, solution quality of LR depends on the method to update Lagrange multipliers. This paper proposes a new hybrid method for solving UC problem. The proposed method is developed in such way that a particle swarm optimization technique is applied to update Lagrange multipliers and improves the performance of LR method. To illustrate the effective of the proposed method, it is tested and compared to the conventional LR [69], GA [69], and HPSO [79] on 4 units test system and 10 units test system, respectively.

Exploring the Experiences of Gender-Based Violence
and The Associated Psychosocial and Mental Health
Issues of Filipino HIV-Positives: Implications for
Psychological Practice
Evangeline R Castronuevo-Ruga1, Normita A Atrillano2
Abstract: The phenomenon of gender-based violence has generated attention from research practitioners and helping professionals since
the surge of the women’s movement three or so decades ago in the Philippines. At about the same time, the HIV-AIDS gained similar
attention with the disclosure of the first ever case of the country in the mid-80s. Only recently, however, has the intersectionality of these
two phenomena been looked into by the research community in other countries and has yet to see parallel response locally. This research,
therefore, attempts to map out the lived experiences of People Living with Human Immuno Deficiency Virus (PLHIV) who have undergone
gender-based violence (GBV). It specially looks into the consequent psychosocial and mental health issues. Using focus group discussion with
24 purposively sampled participants from the highly vulnerable groups based in three major Philippine cities, thematic analysis reveals that
the participants experienced various forms of gender-based violence, e.g., sexual, emotional/psychological, economic, verbal, physical) and
expressions of stigma and discrimination, which in turn, led to manifestations of different emotional and psychological trauma, depression,
internalized homophobia, greater health risks and risk-taking behaviours, among others. It might be worthwhile to consider the possibility
that the consequent risk-taking and self-injurious tendencies played a role in their eventual contraction of HIV.

Politeness and Intimacy in Application Letters of
Three Cultural Groups in Mindanao
Helen G Juaini1
Abstract: 150 application letters from the three cultural groups in Mindano, namely Sinama, Subanen, and Tausug have been analysed
in a mixed-method design. The focus of the study is on the two features of politeness and intimacy. In the quantitative analysis, the model
proposed by Brown & Levinson (1987) and that of Columns (2005) which have drawn upon the features of indirectness in requesting and
the length of letters as the indicators of politeness are used. In the qualitative and descriptive analysis formality in salutation and opening
clause as well as the use of abbreviated forms are taken into account. The result shows that Tausug use the politest style in their application
letters, followed by Sinama and Subanen respectively. On the other hand, Sinama, Subanen, and Tausug use the least intimate style in their
business letters. The findings are hoped to help better inter-cultural understanding, especially with respect to written rhetorical
characteristics.

Abstract: Recently, IoT devices such as robots, speakers, domestic electrical appliances and smart devices are provided everywhere for
everyone. While their authentication request is quite ubiquitously, namely, an authentication for sharing services, the actual
implementations are patchy schemes of variety security policies. In this study, we propose the new authentication scheme for IoT devices
without certificate authority which is fast enough as well as secure. The verification algorithm is based on suitable ciphered metric. We
define a class of such verifiable encryption and give an example for authentication. Moreover, we show the implementation which keeps
perfect secrecy by means of Shannon’s theory.
Developing a Strategic Organisational Learning
Framework to Improve Caribbean Disaster
Management Performance
Joanne Persad1
Abstract: Disasters are social constructs and require an agility and adaptability from national disaster organisations (NDOs). The
environment in which NDOs operate are complex adaptive systems environment, and organisational learning as a key approach is considered
fundamental to strengthening the ability of an NDO to perform at its best. With the potential for loss of lives, the destruction of critical
infrastructure and housing and to the risk of setting back a country’s economic development by many years, learning from the lessons of the
past, to reduce the negative impacts is critical for the onward growth of Caribbean countries which, for the most part, are small island
developing states. The Caribbean Region is the one of the most hazard prone regions in the world (Walbrent College 2012). Lessons from
disaster impacts are identified, gaps are well documented, and failures are sometimes exposed. But learning, in terms of making changes to
improve systems, performance and resilience, is questionable. The lessons must be applied for change to occur, this is part of the knowledge
management process in the context of disaster organisations. The purpose of this study is to explore the apparent inability of national
disaster organizations in the Caribbean to apply the lessons learnt from previous disasters. Three (3) Caribbean countries have been selected
for this research. It is a multiple case study where the unit of analysis is the national disaster organisation. This study is based on an
interpretive paradigm.

Abstract: The West African Sahel is a vast ecological zone separating the Sahara Desert to the north and Sudanian savannah to the
south; traversing Senegal, Mali, Burkina Faso, Niger, northern Nigeria and Chad. With a population estimated at more than 60 million
people, the region features a multiplicity of development challenges. It is home to some of the world’s most impoverished people, whose
livelihoods are mostly reliant on rain-fed agriculture. Characterized by semi-arid vegetation, the West African Sahel is one of the most
environmentally degraded ecosystems in the world. The region faces severe and recurring bouts of droughts since the 1980s, jeopardizing
environmental sustainability. During the past four decades, the West African Sahel has witnessed below-average annual precipitation, with
two severe drought periods in 1972-1973 and 1983–1984, in a development that undermined agricultural productivity and spawned
severe land degradation. Various studies have predicted even more severe climate variability and change in the region, with drier and more
frequent dry periods expected. The intergovernmental Panel on climate change (IPCC, 2007) revealed a decline in annual rainfall in West
Africa since the end of the 1960s, with a reduction of 20% to 40% observed in the periods 1931-1960 and 1968–1990. Repeated
droughts, fuelled by climate change, have undermined land productivity, turning arable soils into marginal lands, and rendering land
resources vulnerable to such anthropogenic activities as over-grazing, agricultural intensification and deforestation, which are common
practices across the region. The major objective of this paper is to shed light on climate change and land degradation patterns in the West
African Sahel. It employs empirical data to analyse the trends, with particular emphasis on Mali, Niger and Senegal. The study reveals
considerable threats posed by the twin scourges of climate change and land degradation to food security, environmental sustainability and
regional stability.

Abstract: The online clothing businesses have seen a considerable rise in recent times, with a high and growing demand. The purpose of
this study is to determine the factors that play significant roles in creating purchase intention towards the online clothing products in
Bangladesh. Secondary research was used to build the model of customer purchase intention. A structured questionnaire was employed to
gather data and test the model. Factor analysis and regression were used to test the model. The regression model suggested that customer
purchase intention was induced most by the online marketing activities of the online retailers, followed by pricing strategy implemented and
sense of security provided (in that order). To understand customer purchase intentions better, it may be important to look at additional
factors or seek better measures of the constructs. The study suggests that online retailers should heavily focus on online promotions and
pricing.

Abstract: Unlike other industries, the construction industry is characterized by its heavy dependence on labour force with most work done
by workers. Still, the industry is witnessing the declining influx of young workers and the rising turnover rates of skilled workers due to such
issues as the advancement of 3D industry, negative image and absence of an established wage system. Hence, this paper proposes an
alternative scheme that would help improve the wage system and work environment for skilled construction workers in Korea.
Mastering the Recycling of Masonry while building
Tadao Ando’s Private Gallery in Lincoln Park,
Chicago
Daniel Joseph Whittaker1
Abstract: The notion of a great presence of masonry rarely conjures up the likes of buildings by master architect, Tadao Ando san of
Osaka, Japan, who is better known for his sublime shaping of space with planar forms of site-cast concrete. Perhaps though, one may recall
the ‘historical intervention’ on a grand scale—the now nine-year-old Punta Della Dogan a project (2009) in Venice, Italy, as prima facie
evidence of his dialogue with a vast quantity of ancient masonry in the Laguna. However, a new project by Ando, recently opened in
Chicago, Illinois (October 2018), presents the private-museum-gallery-going public with a new North American delight. Here, the senses
are able to indulge in a hybrid set of experiences shaped by masonry, concrete, and white painted plaster surfaces. This paper explores how
the modern concrete master has expanded his dynamic architectural vocabulary utilizing what is known as Chicago common brick: a soft,
Lake Michigan-sand and clay based fired brick, and incorporated it into his most recent private commission located in Lincoln Park,
Chicago.

Abstract: Energy consumption is an important factor of com-mutational power these days. Large scale energy consumption results in bad
system performance and high cost. To access frequently used data, we place it in Cache. Cache provides us opportunity to access that data in
a small time. Cache memory helps in retrieving data in minimum time improving the system performance and reducing power consumption.
Due to limited size of Cache, replacement algorithms used to make space for new data. There are many existing cache replacement
algorithms for example LRU, LFU, MRU, FIFO etc. Existing algorithms consume a lot of energy while replacing cold blocks of data.
Replacement algorithms are usually designed to reduce miss rate and increase hit rate. These algorithms replace cold blocks (not going to use
in future) and due to large number of cold blocks, they consume lot of energy. This paper proposes an energy and computation efficient cache
replacement algorithm that put only hot blocks in action instead of removing cold blocks. This paper also discusses different replacement
algorithms proposed in different papers and compare these algorithms on basis of different parameters mainly energy consumption. In our
experiments we have found LRU and FIFO as best replacement algorithms for Increased hit rates and Energy efficiency respectively.
