Abstract: Compared with the roads and reinforced concrete bridges inland, roads and bridges in coastal region is easier to be destroyed which makes its durability lower because of chloride ion erosion. Steel structures in coastal roads and bridges have been corroding by chloride ion for a long time which caused fast collapse after rotten and aged steel appeared. For coastal region, therefore, every year, a large amount of money is used to reinforce and maintain the roads and bridges, which brings serious economic losses and in a way affects the social environment in coastal region.

Abstract: Power transmission with minimum loss is the major criteria while calculating the efficiency of the machine. Most of the machines are using the gear transmission from the input to output but it has the major power loss due to friction. A research in this area brought new ideas to transmit the power using different mechanism. This paper investigates and workouts the new mechanism by replacing the bevel gear with 90º elbow is used to transmit the power. This transmission system indicates that there is the possibility of right angle power transmission without gears in efficient way. In this paper the power is transmitted with six elbows radially connected at an angle of 60º with respect to the center of the axis.

Abstract: The world over, e-government is increasingly becoming an important means of delivering public service due to the numerous benefits associated with it. Despite this however, low uptake and use of the available e-government services has been witnessed in many developing countries. This occurrence is being attributed to the fact that existing technology adoption models don't take into consideration the unique setting of developing countries leading to complete failures or partial successes of e-government projects. To address this problem, the research sought to establish the critical success factors that influence Small and Medium Enterprises (SMEs) in the manufacturing sector in Kenya to adopt and use e-government services. The study findings are intended to help designers, developers and implementers of e-government projects or G2B platform designers recognize strategic areas of focus that will ensure increased uptake and use of e-government services. To realize the main objective of this study, an exploratory approach using a descriptive survey design was used. Primary data was collected using a structured questionnaire and analyzed using statistical package for social science (S.P.S.S). From the findings of the survey conducted from a sample of 124 SMEs, usefulness, ease of use, quality of the website, government regulations and incentives, organization competitiveness due to use of e-government services, faster broadband connectivity, affordable connectivity, network security and data protection and e-government awareness/training were found to be the most critical success factors that influence the adoption and use of e-government services by SMEs.

Abstract: This paper comprises of the Design & Fabrication of a Four Wheel Steering mechanism which relatively is a new technology that improves manoeuvrability in trucks, cars, trailers & other four wheelers. In general two wheel steering vehicles, the rear wheels do not play any role in association with the steering, i.e they follow the path of the front wheels. In a four wheel system the rear wheels are made to turn left & right as per the requirements. To keep the operation as simple as possible a computer controlled mechanism can be incorporated for the rear wheels. The rear wheels can be controlled in the following fundamental ways: At slow speeds the rear wheels turn in the opposite direction of the front wheels. This can reduce the turning radius approximately by 21%. At faster speeds on the highway, the rear wheels are made to turn in the same direction of the front wheels. This improves the lane changing manoeuvrability & is particularly beneficial for vehicle towing. Out of the various possible mechanisms, Rack & Pinion type is being presented in this paper.

Keywords: Four Wheel Steer, Quadra-steer, Steering Mechanisms, Turning Radius Reduction.

Abstract: The age of power transmission evolving from steam engines to internal combustion engines and then to electric power. This electric power can be further simplified and used in the form of an electromagnetic engine. Magnetism is the basic principle of working for an electromagnetic engine. The general property of magnet i.e. attraction and repulsion forces is converted into mechanical work. We plan to change the conventional engines with a new class of engine which work on principle of magnetism electromagnetism and AC magnetic fields. We can say that no such engines exist which can produce no emission and does not take time for starting(charging of battery in electric engines) and the concept of using ac magnetic fields is new for these engines making them much more efficient.

Abstract: In this study, effect of different cutting methods and following normalization heat treatment on microstructure of 316L stainless steel tubings were investigated. 316L stainless steel is the most commonly used material for coronary stent production. Tubings were cut with laser cutting, plasma cutting, oxy-fuel cutting, water jet cutting and electrical discharge machining methods. Cut tubings were characterized by using Scanning Electron Microscope (SEM). Separate samples were prepared for heat treatment operation. 316L stainless tubings were cut with same methods and same parameters. Normalization heat treatment was applied to the samples. Heat treated tubings were characterized by using Scanning Electron Microscope. When results were evaluated, it was seen that laser cutting gives the best results rather than that of other cutting methods in terms of homogeneous microstructure, smoothness of cutting surface, a microstructure without oxidation and distortion etc.

Abstract: Recent developments in information technology have made possible the collection and analysis of millions of transactions containing personal data. These data include shopping habits, criminal records, medical histories and credit records among others. A protocol has been proposed for secure mining of association rules in horizontally distributed databases. This protocol is optimized than the Fast Distributed Mining (FDM) algorithm which is an unsecured distributed version of the Apriori algorithm. Overcome the problem of FDP Using fast Distributed Mining (FDM) algorithm. There are two rules, one that computes the union of private subsets that each of the interacting group of actors hold, and another that tests the inclusion of an element held by one player in a subset held by another. This paper proposed some rule that offers improved privacy with respect to the proposed rule. The main purpose of this protocol is to remove the problem of mining generalized association rules that affects the existing system. This protocol offers more enhanced privacy with respect to previous protocols. In addition it is simpler and is optimized in terms of communication rounds, communication cost and computational cost than other protocols.

Abstract: With the sustainable development of human society in recent years,the existing engineering technology has been changing and improving in architectural engineering field in order to satisfy the development of modern architectural engineering. For so long, however, problems on durability in engineering structure, especially the partial deciding effect of property characterized by concrete material on its durability, as a popular topic have been discussing and analyzing by researchers all over the world. In addition, finding an effective method to change property of concrete material to enhance its durability is a project that lots of researchers would like to do over their lifetime. To comprehensively reveal the unique laws between the property of concrete material during construction period and its durability in the following days, the origin of concrete material must be researched as the first object to understand the early property of concrete material, which is of the foundation to clearly control the research on its durability from macro perspectives.

Abstract: Information security is the technique of defending information from unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction. Data leakage happens whenever a system reveals or disclosed some information to unauthorized parties. We know that in business or in any distribution purpose it is necessary to transfer important data among many business partner and between the numbers of employees. But during this transfer of data information is reach to unauthorized place. So it is challenging and necessary to find leakage and guilty person responsible for information leakage. The goal of this system is to detect guilty person means agent when the distributor's sensitive data have been leaked and if possible to identify the leak data. In this project, we used the methodology for adding fake object into data. Fake object will be added using steganography concept. Steganography is the ancient technique of data hiding used for security. We can say that steganography is the art and science of hiding the existence of information. The ultimate aim of Steganography is to mask the fake data behind the cover file. In this system, we find the guilty person which is responsible for data leakage of video file. Video consist of number frame therefore we add fake data on every frame to increase the chance of detection. Here guilty person means agent is the insider. Insider means the person working in organization. Because in many times, data leakage is happen due to insider.

Abstract: In this modern era of communication optical fiber has emerged as an efficient and viable mode for communication. Though optical fiber communication lot of benefits, dispersion is that the main performance limiting issue. Dispersion severely degrades the performance of fiber. There are numerous ways for dispersion compensation. The fiber is usually used in telecommunication system due to its characteristics that include little size or dimension, low loss and low interferences from outside surroundings. There are numerous varieties of optical fiber compensators, however Fiber Bragg Grating (FBG) is often chosen as necessary parts to compensate the dispersion in optical communication system.

Abstract: This paper presents a flexible design of a PV power conditioning system with energy storage. The planned conditioning unit contains a boost converter (BC), a single-phase inverter, and a bidirectional dc/dc converter connected to the PV side of the BC. The BC regulates the dc-link bus-voltage. The bidirectional dc/dc converter endures battery bank charge/discharge control and PV maximum power point tracking (MPPT). Such design guarantees no change in controller configuration once the storage disconnects. Therefore, the previously required supervisory controller is eliminated. A system control strategy based on sliding-mode control (SMC) ensures a reliable output voltage regulation like fast dynamic response, small steady-state error, and low total harmonic distortion (THD) under step changes and nonlinear loads. A standalone photovoltaic (PV) system with energy storage needs complex control design to require into account the varied operating modes. This paper presents a flexible design of a PV power conditioning system with energy storage is executed.

Abstract: The research was conducted to measure the implementation of Total Quality Management by selected companies in the Bahrain manufacturing industry; and, determine the structural and processes changes the same firms underwent towards successful implementation of the TQM concept. A total of 25 executive respondents (from supervisor to Quality Manager Level) of manufacturing firms participated in the study from September to November 2015. The results reveal that respondent Bahraini manufacturing firms have significantly higher levels of Total Quality Management implementation in the areas of "Use of TQM Methods" followed closely by "Top Management Involvement". Furthermore, the processes and structural changes the organizations underwent in implementing TQM include the identification of TQM champions (those who spearhead the promotion of TQM in the company); identifying and partnering with sources of TQM expertise; selecting the best department where TQM can best be practiced; having the Quality Manager as Head of their Quality programs; and, having Total Quality Management System as their main focus in the formal training of employees. Moreover, in terms of the level of implementation of structural exploration and structure for TQM implementation, companies lean towards more conservative exploration and rigid structure. The implementation of Total Quality Management in terms of the goals set for the effort and as perceived by quality management is perceived to be highly effective and backed by much better financial performance. Finally, it was concluded that the main competitive advantage of TQM implementation is less product and workmanship defects and more efficient operations.

Abstract: The purpose of this paper is to compare the behavior of two types of controllers: a traditional controller, represented by a PID controller, and fractional order controllers, represented by a generalized PIλDµ.The well-known PID is the integer order controller chosen whereas the generalized PID which stands for fractional order robust controller are the fractional order controllers studied. Fractional order controller is widely used in most areas of science and engineering, being recognized its ability to yield a superior control in many dynamical systems. This work proposes the applications of a Fractional Order PID (FOPID) controller in the area of Power Electronics. To design Fractional Order PID controller is to determine the two important parameters ? (integrator order) and µ (derivative order). In this article, the response and performance of closed loop DC - DC converters (Buck, Boost and Buck - boost converter) is compared between two controllers of Fractional Order PID controller and conventional PID controller. In all the cases the Fractional Order PID controller is found much better than conventional PID controller for the given system.

Abstract: In HIV infection the event of significance is the time at which the condition of AIDS begins to develop in an infected individual. Nowak and May (1991) suggested the existence of Antigenic Diversity Threshold (ADT) beyond which the immune system is unable to sustain against the viral populations. It is assumed that the condition of AIDS occurs on crossing this Antigenic Diversity Threshold (ADT). In this paper an attempt has been made to estimate the time to Cross Antigenic Diversity Threshold (CADT) under the assumption that frequent contacts with infected individual has an impact on the antigenic diversity and hence on the development of AIDS.

Abstract: Minerals are essential for human body to regulate the metabolic processes but some elements are also toxic to human body. Seaweeds are taken as food items in different developed and developing countries. So, estimation of minerals composition of seaweeds including the trace metals is important to evaluate food safety. On the other hand, the industrial effluents with pollutant, including toxic heavy metals have adverse effects on the aquatic environment. Different costly conventional treatment technologies are applying for removal of heavy metals from the marine environment. These techniques are economically less beneficial and produce a huge load of toxic chemical sludge on the environment. So, remediation of heavy metals by marine macro algae is a novel eco-friendly alternative approach. The Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) has been applied to analyse elements such as (Ag, Cu, Co, Ni, Mn, Cr, Pb, Zn, Cd, Al, B, Fe, Mg and Na) of some seaweeds. The two separate standard methods of acid digestion were used to estimate the minerals composition. The aim of study is to evaluate the composition of minerals including heavy metal. From this study, it is concluded that in compare to other seaweeds species, heavy metals are present in high amount in Valoniopsis pachynema, so this species may be used as heavy metals remediator and is not safe to consider as edible. Accordingly, Codium tomentosum and Gracilaria opuntia contain high amount of aluminium, sodium and boron, so these species should also not be consider as edible.

Abstract: In the recent years rapid development of power electronics and their usage in domestic applications is the major cause for low power quality in distribution system .This can also be due to insufficient VAR support and load unbalance. Power quality problems are mainly classified into three categories. They are voltage fluctuations (sag, swell & flicker), harmonics, low power factor. In all the power quality problems voltage sag and swell are frequently occurs and affects consumers largely. This power quality problem is mitigated by different custom FACTs devices like SVC, TCR and DSTATCOM etc. In all DSTATCOM gives better performance because of faster response, large operating region. In this project the performance of DSTATCOM is verified to mitigate voltage sag , swell , sudden loading and source harmonics in distribution system. It is also verified with soft computing techniques like fuzzy. The results of soft computing techniques are compared with PI control. The distribution system, DSTATCOM and controllers are simulated in MATLAB/SIMULINK.

Abstract: Machining process is the most important operations in many manufacturing industries. One of the important parts of machining is turning process. Turning is a manufacturing process where the excess of material is removed from the work-piece. Machining process consists of characteristics such as surface roughness, material removal rate and accuracy which will determine the quality of the product. The quality of the product is dependent on surface roughness, where as the material removal rate will determine the rate of productivity and the accuracy will give the dimensional tolerance. These characteristics are dependent on the factors such as speed, feed and depth of cut turning operation is one of the most basic machining processes. Turning can generally be done both on the inner and outer surface. The starting material is a work-piece which is generated by other process such as casting, forging, extrusion or drawing. Proper setting of cutting parameters is important to obtain the better surface finish, accuracy and material removal rate. Unfortunately, conventional trial and error method is most time consuming and requires high cost. The purpose of this study is to determine the most significant parameters and its optimum range in CNC turning using various statistical tools such as Analysis of Variance (ANOVA).

Abstract: The designer of an FPGA embedded processor system has complete flexibility to select any combination of peripherals and controllers. In fact, the designer can invent new, unique peripherals that can be connected directly to the processor bus. If a designer has a non-standard requirement for a peripheral set, this can be met easily with an FPGA embedded processor system. For example, a designer would not easily find an off-the-shelf processor with ten UARTs. However, in an FPGA, this configuration is very easily accomplished.

Abstract: Food industry requires a large quantity of water for various processes. Compared to other industrial sectors, food industry requires more water, used in throughout most of the plant operations, such as production, cleaning, sani-tizing, cooling and materials transport, among others. The treatment mechanisms of contaminants in wastewater are highly dependent on the design and operational characteristics of the wastewater treatment plants (WWTPS). The membrane biological reactors (MBR) have proven to be efficient for the treatment of industrial wastewaters over conventional wastewater treatment plants when treatment efficiency is an important consideration. The present study aims to analyze effectiveness of membrane bioreactor technology as a modern tool to minimize the water pollution level caused by noodle, curd, and infant food plants. The analysis of pollutants in influent and effluent from food industry was done on the monthly basis. The pollution indicators (BOD, COD, total suspensions, temperature, appearance, and pH) of wastewater of food industry had high values but they remained within the range after treatment in the MBR. When analyzed at monthly intervals, 98% BOD5 and above 99%, COD removals were achieved. Overall efficiency of removed pollutants as COD, BOD and TSS from the wastewater was more than 90%. MBR technology is thus a better and advanced method to treat wastewater of food industries.

Abstract: A microscopic theory of magnetoelectric (ME) effects in multiferroic RCrO3 compounds, where R is a non-magnetic ion (R = Y, La, Lu and Eu) is presented. Taking into account the influence of polar lattice displacements on symmetric and antisymmetric exchange interactions, two types of coupling between the magnetic and the ferroelectric subsystems are defined. The first magnetoelectric interaction is biquadratic with respect to the spin and pseudo-spin operators. The second, called antisymmetric, is induced by the appearance of spontaneous polarization in RCrO3. The built-in microscopic model describes the occurrence of a temperature-dependent spin-reorientation (SR) transition and defines it as continuous (continuous rotation of the magnetic spins in the zx -plane within a given temperature interval). The emergence of additional polarization as a consequence of a magnetic phase transition has been proven theoretically. This is due to the induction of an antisymmetric magnetic interaction of type Dzyaloshinsky-Moriya (DM) interaction, which is a consequence of the occurrence of spontaneous polarization in these compounds. The influence of magnetoelectric interactions on the magnetic and ferroelectric subsystems has been investigated. The behaviour of magnetization at the application of an external electric field is qualitatively explained with the renormalization of the exchange symmetric and antisymmetric magnetic interactions by the spontaneous polarization PS. The dependence of spontaneous polarization on the direction of external magnetic field was explained by the occurrence of feedback between PS and magnetization. It has been established that the width of the temperature interval ??SR, in which the SR transition takes place, decreases with the increase of the value of the external magnetic field. The method of Green's function is used for the numerical calculations.

Keywords: multiferroics, magnetoelectric interactions, Green's functions, spin-reorientation transition, induced Dzyaloshinsky-Moriya interaction.

Abstract: In this research work, ECG of 10 subjects is recorded using the BIOPAC MP 100 system with Acknowledge software. The recorded signal is pre-processed to remove the unwanted high frequency signal, so it is filtered using Low Pass FIR filter with 40 Hz cutoff frequency. Statistical Parameters such as mean, variance, standard deviation etc are used to support the uniqueness property of an ECG signal for each subject. The classifier used in this research work is the Artificial Neural Network (ANN), which is trained with the extracted features. The error in prediction of the ECG of 10 subjects is nearly zero. So the accuracy of the identification system is 100%.

Abstract: Covert network timing channels control time between transmissions of packets in overt network communication and transmits hidden messages. This paper presents an overview of different concepts of covert timing channels such as types, features and properties. There is range of terms used for security of information such as encryption, covert channels, network steganography or information hiding in network protocols. Information is hided into network protocols in case of covert channel, but information is hided into content in case of steganography. Different applications such as VoIP, SSH use covert timing channels for the purpose of security. In earlier days, encryption was only the parameter used for security; so information was not secure however simply using encryption does not prevent detection of communication patterns, so various techniques are developed. The main properties of covert timing channels are undetectability and robustness. Unauthorized access from criminals, hackers & terrorists is avoided by using covert timing channels etc. But there are some negativities of covert timing channels, e.g. terrorists misuse covert channels to coordinate their actions. This paper also discusses about use of covert timing channels and types along with applications and problems occur in covert timing channels.

Abstract: Rotating machines plays a vital role in modern industries from small scale to huge power plants. The soul of the rotating machine is shaft and entire load of the shaft is taken by the bearings. Bearing health plays a significant role in the performance of rotating machines either machine consumes power or generates power. This article presents the experimental investigation of journal bearing performance with a helical groove cut on the journal. The results of the investigation on a bearing with a helical groove on the journal (load capacity, oil temperature, and oil flow rate) were compared with those obtained for a standard bearing with a plain journal. The previous computer simulation results, indicated that a groove of appropriate dimensions on the journal intensifies axial oil flow and does not impair load capacity. The complete experiment was performed on the bearing apparatus. The results shows that the shaft have grooves on its surface delivers better performance than that of standard plane shaft. The shaft having grooves controls the temperature rising at various speed of the shaft and generate less torque in comparison to the shaft that have no grooves. This investigation shows that the dimension of the groove plays a vital role in improving the bearing life and its performance because an appropriate size groove can control the temperature rising at higher speed without effecting the load bearing capacity of the bearing.

Abstract: Pollution is one of the major concerns on the globe today. Farmers use a variety of chemical fertilizers to increase production and manage weeds and insect pests in order to meet the demand for agricultural products and to feed the growing population. Synthetic pesticides and fertilizers have been utilized excessively, which has had a negative impact on both the environment and human health. As a result, the greatest important hazard to humanity on the planet is the increasing degradation of environmental contents. The imbalance between human needs and resource sustainability was accelerated by the rapidly expanding population in developing nations. The use of chemical fertilizers in agriculture has caused numerous environmental and health issues while increasing agricultural productivity. Water pollution is mostly caused by phosphates and nitrates found in chemical fertilisers.
