Abstract : Reinforced concrete (RC) beams have been found to be deficient in torsion resisting capacity and in cases where Torsional moments are substantial there is a need of strengthening these beams to resist these moments. These deficiencies occur for several reasons. Investigations have been done on concrete beams retrofitted with glass fiber reinforced polymer (GFRP) composites in order to study the enhancement of strength and ductility, durability, effect of confinement, preparation of design guidelines and experimental investigations of these members.

Abstract : Image compression addresses the problem of reducing the amount of data required to represent a digital image. There are some areas of medicine where it is sufficient to maintain high image quality only for diagnostically significant regions, for example, tumor section of the brain MRI. This paper represents a compression method based on ROI and its performance analysis focusing on Discrete Cosine Transform technique. It is used for reducing the redundancy that is nothing but avoiding the replica data. The DCT is a mathematical function that transforms digital image data from the spatial domain to the frequency domain.

Abstract : This work aims to evaluate the implementation of e-learning platforms in schools in Egypt along with promotion of Islamic values. E-learning has been a topic of increasing interest in recent years. In this paper we suggest to combine the areas of e-learning and Web services, by providing electronic learning offerings as (individual or collections of) Web services as well. We elaborate on this by showing how content providers and content consumers (i.e., learners) can communicate appropriately through a Web service platform with its common description, publication, and retrieval functionalities. Since Egypt has been known as a country where many children are not able to have an appropriate education, e-learning platform would provide students with the ability to study even if they live in remote places. Moreover, the integration of new technologies in the classrooms opens new possibilities for the teaching and learning process. Technologies such as a student response system are getting popularity among teachers due to its effects on student learning performance. In this study, our primary objective is to investigate the effect of e-learning platform with combination of Islamic teachings on students learning performance. We also observed the benefits of interactivity between the teacher and the students and among classmates, which positively influences collaborative learning and engagement of students in the class. The results of our study reveal that collaborative learning and engagement of student in the class improves student learning performance. We highly recommend these tools in educational settings to support the learning process.

Title : An Experimental Investigation of Electrode Wear Rate Using EDM with Different Electrode Materials


Click Here For Abstract

Abstract : Electrical discharge machines (EDM) remove metal from a work piece by using a series of electric sparks to erode material. An electrical discharge machine is considered to be the most precision oriented manufacturing process and is widely used for creating simple and complex shapes and geometries. EDM is a machining method primarily used for hard metals or those that would be impossible to machine with traditional techniques. One critical limitation, however, is that EDM only works with materials that are electrically conductive. EDM is especially well-suited for cutting intricate contours or delicate cavities that would be difficult to produce with a grinder, an end mill or other cutting tools. Different electrode materials shows a great influence on the desired quality so here we have focused some different electrodes that we can use for surface modifications and better results so that the way ahead has been opened for further scope of work. The results reveal that low electrode wear rate (EWR) has been achieved with copper electrode (0.06 mm3/min) and brass electrode gives more electrode wear rate among other two electrodes.

Abstract : In India, the National Bank for Agriculture and Rural Development (NABARD) reports that there are many lift irrigation schemes financed by them. These schemes irrigate most of the hectares of land. However, as many of these schemes are defunct, mainly due to poor distribution of water. Other schemes have been financed by individual farmers are on the way of defunct due to poor distribution of water. In normal systems, the area is divided into three or four equal parts, and each part is given the entire discharge for one day. This means each part gets rotation of the full design discharge on the fourth or fifth day. However water distribution can be unequal, To overcome the unequal distribution of irrigable water by most efficient method i.e. “EQUAL AND PROPORTIONATE WATER DISTRIBUTION SYSTEM” can be adopted. The salient features of this system are: Every farmer gets precisely equal or proportionate water to his area under irrigation and investment at the same time. As per the availability of electricity, as long as the pump is running, all the farmers will get EQUAL and PROPORTIONATE DISCHARGE. The dependability or reliability of the scheme is increased among the farmers. There is no need of an operator. Since equal or proportionate distribution is fool proof, certain and doubtless. While designing new schemes, we give water on the basis of shares rather than based on crop and area to be irrigated. We therefore decide a shares of water and farmer decides how many shares he wants, and share capital and recurring expenses accordingly. He has then freedom to take any crop and to irrigate any amount of area by using water saving techniques like micro irrigation and mulching etc.

Title : Enhancing Text Mining by inducing Side-information with Ontology

Authors : Atiya Kazi , D.T.Kurian

Click Here For Abstract

Abstract : There are several text mining applications where, the side-information contained within the text document may be considered as part of the clustering process. This side-information can be related to document provenance, which provides the author information, hyper links within the document to navigate between web-pages, user-access behavior pattern gathered from web logs, or images within the document. The proposed algorithm, which performs clustering of data along with the side information, combines classical partitioning algorithms with probabilistic models to increase the effectiveness of the clustering approach. The algorithm will be further extended to the classification problem to design a training model using the side-information. The proposed work will then generate target ontology, from saved user preferences and will then use the same in order to improve the effectiveness of text mining approaches. This will enhance the structuring of knowledge gained from text documents by incorporating the ontology as well as side-information. The advantage of incorporating side information over pure text-based clustering is that the side information can be vastly edifying, and it also contributes to creating more lucid clusters.

Authors : Rohit Sharma, Atma Prakash Singh

Click Here For Abstract

Abstract : The growing need of intelligent computing focuses on utilization of Multi-Agent system. Various fields like medical diagnosis, production planning, network monitoring, intelligent tutoring, education planning, production management etc. are facilitated by using MAS based approach. As MAS is an emerging technology where complex problems are solved with collaboration, coordination and communication between agents where Agent can be simply viewed as self-described autonomous software component or piece of codes. Here agent’s capability and its characteristics like reactivity, pro-activeness, social ability etc. are used to facilitate applications in power engineering. Multi-Agent System will be beneficial for the construction of powerful, flexible, scalable and extensible system. It also reduces the power system failure and fault occurrence rate. MAS provide capability to power systems to reconfigure themselves. It will have less failure rate. This paper mainly focuses on handling issues of power system like conditional monitoring of plant and equipment by gathering data from sensors, diagnosis from faults, distributed control of power system etc. by mean of Multi-Agent system. In this paper the proposed MAS based model shows the approach to solve these issues mentioned above with the help of various agents. Each agent is either partially or fully independent of each other. The distributed problem solving approach is used to solve these issues. Agents communicate and co-ordinate with each other in order to reduce faults. Several agents are used to monitor and diagnosis from faults. Agents will interact with sensors and from there they will get data with will be further converted into meaning full information’s. In case of occurrence of faults agents generate a diagnosis conclusion with help of several algorithms.

Title : Can oil prices forecast the Algerian exchange rate?

Authors : Kamel Si MOHAMMED, Sidahmed ZENAGUI, Abderrezak BENHABIB

Click Here For Abstract

Abstract : The goal of this study is to investigate the relationship between oil price and nominal US Dollar/Algerian Dinar exchange rate through an empirical analysis using a VECM Model (Vector Error Correction Model) upon monthly data for the period 2008-2015. Results show that a cointegration relationship is detected between oil and exchange rate in Algeria, with bilateral trend causality in short and long run time horizon. Furthermore, the out-of sample predictive indicates that a change in oil price would tend to depreciate Algerian Dinar against US Dollar. This negative impact emphasizes how the Algerian dinar is a non-oil currency and explains how the foreign exchange receipts from hydrocarbon exports help swell Algerian public spending that would cater for public budget deficit curtailment.

Abstract : The aim of this study is to create a new polymer based composite for a radiation shield where we used polyurethane as a matrix material incorporated with different materials (ordinary Portland cement , aluminum filings ,epoxy ,salt and rice husk) as fillers. The new compound is less expensive than other shielding materials due to the substantial reduction in part weight, ease of fabrication, wide area etc .Both rice husks and oyster shells are common wastes thatare used as fillers to the fabricated composite . the linear attenuation coefficient, mass attenuation coefficient, half value layer and mean free path have been calculated .The study also investigated the effect of the curing method where three types (moisture, water and dry)have been used due to the use of ordinary Portland cement .The results obtained show that the three curing methods have the same effect on the efficiency of gamma radiation shielding. Also they reveal that the obtained results show the increase of the removed photons from gamma rays with the increase of the absorber material thickness which is similar to the effect of the aging factor. Finally the results obtained show that the oyster shell particles have increased the shielding efficiency of the fabricated composite more than the same composite filled with rice husk particles.

Abstract : As companies worldwide struggle to move beyond the great recession of 2009, many business leaders are adjusting their talent strategies to meet the shifting demands characterized as the “new normal.” While the inclination may be strong to revert to strategies that served them well prior to the economic crisis, many executives seem to recognize that the forces shaping future talent needs, such as globalization and an aging workforce, continued to accelerate during the downturn and now require new talent strategies to position their companies for success. This aims at exploring talent strategies, concerns of global companies, and unfolding employee trends as companies confront a fresh set of challenges that we expect will influence the next decade and beyond. The constraints of talent & quality of manpower at the entry level, yet, by and large, the industry has been able to get the required numbers albeit with some compromises with what they were looking for. Surprisingly most of this so called “unemployable” lot of students have risen to the demand upon selection, demonstrated the capability levels expected of them & ultimately settled down into successful careers and delivered substantially the results expected out of them. Many of the students at the bottom of the ladder, from amongst those who really needed the jobs, had to start off on petty stipends, and through structured learning or due to “hands on” learning & growth at the work place, a few years down the line, many of them have entered into reputed multinational companies. Key words: seek to improve the skill set of graduates; emphasize Soft Skills, Potential based selection, refocus the assessments, interact more with employers to understand the particular demand for skills in that region and sector-Domain skills, Work Place Competencies, skills do employers consider important when hiring new engineering graduates.

Abstract : This paper studies the challenging problem of energy minimization for data gathering over a multiple-sources single-sink communication substrate in wireless sensor networks by exploring the energy-latency tradeoffs using rate adaptation techniques. We consider a real-time scenario for mission-critical applications, where the data gathering must be performed within a specified latency constraint. We first propose an offline numerical optimization algorithm with performance analysis for a special case with a complete binary data gathering tree. Then, by discretizing the transmission time, we present a simple, distributed on-line protocol that relies only on the local information available at each sensor node. Extensive simulations were conducted for both long and short-range communication scenarios using two different source placement models. We used the baseline of transmitting all packets at the highest speed and shutting down the radios afterwards. Our simulation results show that compared with this baseline, up to 90% energy savings can be achieved by our techniques (both off-line and on-line), under different settings of several key system parameters.

Title : Energy efficient building structure

Authors : Seema Mahto, V.N. Bartaria, R.K. Agarwal

Click Here For Abstract

Abstract : There are many factors which affect the heat load of the building. Factors such as solar heat gain in summer, heat loss in winter, and natural ventilation in transitional seasons must be considered when designing energy-efficient residential buildings for hot summer/cold winter zones In this paper we have discussed the various factors affecting the heat load of any buildings. The heat transfer process of building envelopes differs in summer and winter, and heat and mass (e.g., moisture) transfer must be considered when providing natural ventilation. It is impossible to design energy-efficient buildings using only one approach, such as lowering the heat transfer of exterior walls, roofs, and windows or increasing the thickness of thermal insulation. The coupling of thermal mass and natural ventilation is important to passive building design. In this paper we are going to discuss various option for energy efficient building design.

Title : Dynamic Power Reduction of SRAM memory

Authors : Isha Gautam

Click Here For Abstract

Abstract : Low power static-random access memories (SRAM) has become a critical component in modern VLSI systems. In cells, the bit-lines are the most power consuming components because of larger power dissipation in driving long bit-line with large capacitance. The cache write consumes considerable large power due to full voltage swing on the bit-line. The aim of the paper is to propose a new SRAM cell architecture to reduce the power consumption during write 0 and write 1 operation. The paper proposes a SRAM cell to reduce the power in write “0” as well as write “1”operation by introducing two tail transistors The proposed SRAM cell consumes less power than the conventional SRAM cell during write operation. The write access delay is reported to be lower than conventional. The Proposed SRAM cell designed and implemented with using .012µm CMOS technology. Simulation is performed by Microwind 3.1 & DSCH2 software. We design a 64-bits memory with the help of Proposed SRAM cell and finally the results are compared with Conventional 6T SRAM 64-bit memory. The power dissipated in Proposed SRAM memory is reduced up to18.88% in comparison to Conventional SRAM memory.

Authors : Dileepkumar T Sahu, Ketul Brahmbhatt, Nilamkumar S Patel

Click Here For Abstract

Abstract : In recent years, there has been a marked increase in interest in biodegradable materials for use in packaging, agriculture, medicine, and other areas. In particular, biodegradable polymer materials (known as biocomposites) are of interest. Polymers form the backbones of plastic materials, and are continually being employed in an expanding range of areas. As a result, many researchers are investing time into modifying traditional materials to make them more user-friendly, and into designing novel polymer composites out of naturally occurring materials. A number of biological materials may be incorporated into biodegradable polymer materials, with the most common being starch and fiber extracted from various types of plants. The belief is that biodegradable polymer materials will reduce the need for synthetic polymer production (thus reducing pollution) at a low cost, thereby producing a positive effect both environmentally and economically. This paper is intended to provide a brief outline of work that is under way in the area of biodegradable polymer research and development, the scientific theory behind these materials, areas in which this research is being applied, and future work that awaits.

Abstract :

Air powered vehicles are those which can run on no external aids. In spite of electrical vehicles, these vehicles do not wait for recharging for longer period of time. Refuelling is easier and can be done in fraction of minutes. Most importantly it is having utmost same efficiency without compromising any kind of losses. At present the air technology in the automobile sector is very scarcely been used because of their low range of travel with single fueling. Our system deals with an attempt to make a more efficient air engine to give few more miles to get incorporate with. An attempt is made to convert two wheeler in compressed air charged rotary engine system, by providing air drive with specialized air tank which can hold up to 300bars or 4000psi of pressurized air to reduce space required for fuel (air). Rear wheel drive will serve initial pick up torque which will help the required modifications to vane angle as low as possible.
