1 Experimental Analysis and Optimization of Electrical Discharge Machining on Titanium GR-2 with FEA
P. Raja, G. Ramamoorthi, Dr. G. Nallakumarasamy
Abstract - High residual thermal stresses are developed on the surfaces of Electric Discharge Machined parts because of the high temperature gradients generated at the gap during Electrical Discharge Machining (EDM) in a small heat-affected zone. These thermal stresses can lead to micro-cracks, decrease in fatigue life and strength and possibly catastrophic failure. The results of the analysis show high temperature gradient zones and the regions of large stresses where, sometimes, they exceed the material yield strength. A transient thermal analysis assuming a Gaussian distribution heat source with temperature dependent material properties can be used to investigate the temperature distribution. In this project, a series of experiments has to be conducted with copper electrode as a tool and Titanium alloy as work piece to machine small depth on the work piece.The combination of gap voltage, Ampere setting were new line considered for maximum Material Removal Rate (MRR), Surface Roughness (SR), and minimum machining timing. . The main aim was to identify the electrode which could enhance the production of quality of impression and to have a significant contribution for modern industrial requirements. The experiments were carried out as per L9 orthogonal array with each experiment performed under different conditions of such as Ampere rating, sparking voltage while machining. Thermal gradient and Thermal flux also evaluated ANSYS 11.

5 Extraction of Waste Plastic Oil as a Replacement for Diesel
G. Sarath, S. S. Jayaraman, Dr. G. Nallakumarasamy
Abstract - To satisfy the increasing population dependence on transportation, plastic oil is extracted and added along with petroleum products. Plastics which are considered as hazardous to environment pose severe threat to the living beings. In order to reduce the waste plastics and prevent the environmental damage plastic recycling is being done. Blending up of plastic oil with diesel makes the transportation process as more feasible one. Waste polyvinyl chloride (PVC) has been collected and made to undergo thermal pyrolysis which is being maintained at temperature of 450oc in the absence of oxygen. The oil collected by this process was found to be less when compared with the oil which is being collected using the catalyst BaCO3 .The percentage amount of oil extracted by using the catalyst was found to be 20% higher than that of the oil extracted without using catalyst. In the catalytic pyrolysis the increase in the quantity of catalyst increases the amount of the liquid products obtained and reduces the time required. The obtained oil by this process was made to undergo for property test and the results were compared with property test of diesel.

7 Dynamic Clustering SOAP Messages Based on Compression and Aggregation Model to Improve Web Services Performance
Nikhil R, Sankarram C
Abstract - In Software projects, Web services can be viewed as Internet-based communications that share resources, software and information which is supposed to be available on demand for a wide range of clients over the Internet. It can also be described as the communication middleware between the servers and their clients over the Internet by establishing a connection by Hyper Text Transfer Protocol or other well-known protocols. Along with the standardization of Web services composition language and the widespread acceptance of composition technologies, Web services composition is becoming an efficient and cost-effective way to develop modern business applications. As Web services are inherently unreliable, how to deliver reliable Web services composition over unreliable Web services is a significant and challenging problem. Websites cater to millions of customers. The Web Service Oriented Architecture (SOA), an ontology rooted in the Web Services Description Language (WSDL), and modeled as a hierarchical task network for the dynamic formation of business processes when clients call these services. The extension and augmentation of traditional web services describes the business processes as a dynamic clustering of these decomposable business tasks encompassing all possible decomposition permutations. They offer services to clients dynamically. Some common services are accessed by the clients from the web services using SOAP(Simple Object Access Protocol). But when the number of requests increases the web services load increases and creates bottlenecks. The SOAP messages cause imbalance and results in poor delivery. To overcome this the model proposes aggregation of similar services and compression. The requested similar web services are first aggregated, then compressed and processed. This model reduces bottlenecks and aggregates the web services.

9 Data Sharing in the Cloud and Ensuring Accountability
Mailud Mohamed Mailud, Dr. W. Jeberson, Salah Boubkar Salah
Abstract - In cloud computing environment resources are shared among various clients and it's important for system provider to allocate the necessary resources for the clients. As the sizes of IT infrastructure continue to grow, cloud computing is a new way of virtualization technologies that enable management of virtual machines over a plethora of physically connected systems. Cloud computing enables highly scalable services to be easily consumed over the Internet on an as-needed basis a major feature of the cloud services is that users' data are usually processed remotely in unknown machines that users do not own or operate. While enjoying the convenience brought by this new emerging technology, users' fears of losing control of their own data (particularly, financial and health data) can become a significant barrier to the wide adoption of cloud services. Here the multi-layered architecture is proposed to address accountability of the data while sharing in the multi user, heterogeneous and distributed computing environment. The multi-layered architecture is evaluated and shows that the accountability of the data is ensured which increases the trust between the end user and the service provider.
10 Energy Efficient Cupola Furnace via Hybridization with a Biomass Gasifier
M.H. Garba, R.K. Jain, Amit Tiwari
Abstract - The energy efficiency of any foundry largely resides on efficiency of the melting process. High price and limited supply of coke will continue to press the need for devising a way to cut down its demand or developing more energy-efficient solutions for the melting process. This work tries to address the issue by proposing and analyzing a way of reducing coke consumption in a foundry cupola studied, by hybridizing it with biomass wood gasifier. Wood fuel is very cheap and readily available. It can be used to heat the blast air going through a cupola furnace by burning in a gasifier. 800 0C of gas at 16 g/s will be available to heat up the blast air entering the studied cupola of Asia Sewing Machine's foundry to at least 475 0C if hybridized with the 20 KWe downdraft biomass gasifier model studied by Sharma. This is enough to cut down the coke consumption by 133 Kg from 430 Kg used to melt 3450 Kg of metal charge at present. Analysis has shown the coke energy efficiency to improve from 43% to 62.4%. The stoichemetric air/fuel ratio required for both the gasifier and the cupola is found to be 7.86 and 10.52 respectively for proper combustion of their respective fuel. The chemistry in the various stages of the cupola furnace and reasons for that huge percentage of heat energy loss during melting process was properly discussed. It is possible to achieve a less coke demanding cupola furnace by hybridizing with a biomass gasifier. This would greatly reduce the amount of coke consumption in a foundry by using a cheaper and more readily available energy source that consumes gradually to supply a hot air blast (wood etc).

Kiget Kipkurui Nicholas, Karume Simon, Dr. Mugeni Gilbert
Abstract - Use of grid computing as a distributed computing paradigm for collaborative research in universities cannot be over emphasized. It is a technology which provides a platform on which computing resources from heterogeneous systems are brought together as needed by the users. Collaborating researchers who require huge computing resources can use this technology to do their work. A number of universities are in the process of adopting this technology however appropriate model to make the process easily achievable in developing countries' context is lacking. This study focused on developing grid computing adoption model for collaborative research in Universities in developing countries. The study had four objectives; to find out how universities that participated in UNESCO-HP brain gain and HP Catalyst initiatives engaged in collaborative research, to determine the extent of grid adoption in the selected universities, to evaluate critical success factors for adoptability of grid computing, and, to develop grid adoptability model for collaborative research. The study based on positivist philosophy adopted mixed methodology and survey design. The population targeted was the universities and research institution mainly in developing countries. The researcher used East Africa as a cluster zone and identified four Universities that participated in UNESCO-HP initiatives as a sample; University of Nairobi (UoN) and Masinde Muliro University of Science and Technology (MMUST) in Kenya, Makerere University (MU) and Mbarara University of Science and Technology (MUST) in Uganda. The instruments used were structured questionnaires and interview guides. In this paper, we present results of the first two objectives of the study.

13 Bacteria Genetic Engineering
Viyada Viyasar Kannan Ramakrishnan, Anshul Bhatia, Rishabh Ganjoo and Shail Chouksey
Abstract - Molecular communication holds the promise to enable communication between nanomachines with a view of increasing their functionalities and opening up new possible applications. Due to their biological properties, bacteria have been proposed as a possible information carrier for molecular communication, and the corresponding communication networks are known as bacterial nanonetworks. Individual molecules are to be used as building blocks to develop nanomachines but nanomachines cannot be assembled molecule by molecule with the existing technologies. So in the bio-hybrid approach, the naturally existing biological nanomachines are genetically modified by means of molecular engineering to achieve effective communication in the complex nanonetworks. In this paper, few major reasons for choosing bacteria genetic engineering to aid the encoding process and ways to incorporate information in genome along with the various applications of using bacteria as the information carrier are discussed. The challenges and the current advancements in the field of molecular communication are also analyzed.
14 DWT-OFDM Using DAPSK Modulation over AWGN, Flat Fading and Frequency Selective Channels
Ajeet Singh Thakur, Ritu Dubey
Abstract - Orthogonal frequency division multiplexing (OFDM) is a modulation technique that is widely used in many wireless communication systems. Now-a-days the requirements of wireless communication are to have high voice quality, high data rates, multimedia features, lightweight communication devices etc. But the wireless communication channel suffers from much impairment. One of them is fading which is due to the effect of multiple propagation paths, and the rapid movement of mobile communication devices. In a typical wireless communication environment, multiple propagation paths often exist from a transmitter to a receiver due to scattering by different objects. So, this is necessary to reduce the problem of fading. In traditional OFDM based on fast Fourier transform (FFT) and discrete cosine transform (DCT) high side lobes are created. Hence, OFDM based on discrete wavelet transform is used in this work. DWT is more flexible in terms of data rate and has much lower side lobes than traditional OFDM. In this work, the performance of OFDM based on DWT is compared with that of traditional OFDM based on FFT and OFDM based on discrete cosine transform (DCT) through the use of differential amplitude phase shift keying (DAPSK) as modulation scheme. These systems are simulated over additive white Gaussian noise (AWGN), flat fading, and frequency-selective channels through MATLAB software. Simulation results reveal that the performance of the proposed system is better than that of the other two systems over all types of channels.
