Pages: 547 - 552
Recent geotechnical research shows that geothermal heat can be efficiently mined by circulating carbon dioxide through naturally permeable rock formations -- a method called CO2 Plume Geothermal -- the same geologic reservoirs that are suitable for deep saline aquifer CO2 sequestration or enhanced oil recovery. We present an approach that uses huge fluid and thermal storage capacity of the subsurface ,together with geological CO2 storage , to harvest , store ,and dispatch energy from subsurface(geothermal) and surface (solar, nuclear, fossil) thermal resources, as well as energy from electric grids. Captured CO2 is injected into saline aquifiers to store pressure and provide as additional fuel for efficient heat extraction and power conversion .Concentric rings of injection and production wells are used to create a hydraulic divide to store pressure,CO2 and thermal thermal energy. Geothermal power and energy storage applications may generate enough revenues to justify CO2 capture costs.

One of the biggest challenges in the current ticketing facility is "QUEUE" in buying our suburban railway tickets. In this fast growing world of technology we still stand in the queue or buy with ATVM smart cards and coupons for our suburban tickets, which is more frustrating at times to stand in the queue or if we forget our cards. This paper Android Suburban Railway (ASR) ticketing is mainly to buy the suburban tickets which is the most challenging when compared to booking the long journey tickets through 'MÂ ticket' which fails with suburban(local travel) tickets. Our ASR ticket can be bought with just a smart phone application, where you can carry your suburban railway tickets in your smart phone as a QR (Quick Response) code. It uses the smart phones "GPS" facility to validate your ticket. User's ticket information is stored in a CLOUD database for security purpose which is missing in the present suburban system. Also the ticket checker is provided with a checker application to search for the user's ticket with the ticket number in the cloud database for checking purposes.

Pages: 561 - 565
Wireless sensor networks constitute of sensor nodes which are small in size, running on battery, limited computation power, memory and communication capability. Operational environment of sensor nodes is generally unfavorable and unattended which may result in failure of sensor nodes and they are prone to various malicious attacks. One of these attacks is Sybil attack. Sybil attack is harmful enough to get attention of researchers. In Sybil attack a malicious node illegally forges an unbounded number of identities to present an illusion to the network as if it were different legitimate nodes. We propose here a key management protocol that will prevent any such attacks.

Year: 2015, Volume:1, Issue : 12
Pages: 566 - 577
Due to the improperly treated and unplanned release of effluents of industry, municipal and domestic into the nearby streams and ponds and the majority usage of water for irrigation are increasing the ionic concentration of the river water and making it more saline. In order to assess the water quality, the present study has been undertaken to map the spatial variability of water quality using Geographical Information System (GIS) approach. Periyar river is the main drinking water resource of Cochin corporation, Aluva and Paravur towns. The water quality data for 20 sampling stations were collected from Pollution Control Board (PCB). The spatial variation map for the major water quality parameters are generated using Arc View 9.3.1 software tool (i.e.,) Inverse Distance Weighted (IDW).To analyze the pollutant sources, landuse/land cover change detection is needed. Geographical Information System (GIS) is a potential tool to detect the landuse/land cover changes using toposheet and satellite images. From this study, the water pollution sources were identified. Finally, water quality integrated system is designed using Visual Studio 2010 and asp.net. All the above information (i.e.,) landuse/land cover information and water quality information were integrated into this system. This water quality integrated system used by the State and Regional Water Quality Control Boards to track information about water quality and also it allows online submittal of information by Permittees within certain programs and makes data available to the public through reports.

Mechanical Engineering
Year: 2015, Volume:1, Issue : 12
Pages: 578 - 590
In an engine the purpose of the piston is to transfer force from expanding gas in the cylinder to the crank shaft via a piston rod. Piston has to endure the cyclic gas pressure and the inertial forces at work, and this working condition may cause the fatigue damage of the piston such as piston side wear, piston head cracks and so on. Usually the pistons are made of Aluminum for lightweight, thermal conductivity. But it has poor hot strength and high coefficient of expansion makes it less suitable for high temperature applications.In this project, Aluminum Silicon Carbide (AlSiC), an aluminum matrix composite is used as an alternative for aluminium. A 3D model was made using CATIA v6 and Structural and thermal analysis was done on ANSYS 14. Compared to Aluminium, AlSiC has better abrasion resistance, creep resistance, dimensional stability, exceptionally good stiffness-to-weight and strength-to-weight ratios and better high temperature performance. Fabrication of piston using AlSiC is also easier than using Aluminium.

Pages: 591 - 597
This research work presents design, simulation and comparison of microstrip patch antenna designed using different feed techniques. The Microstrip feed techniques are microstrip line feed, inset feed, coaxial feed, aperture coupled feed and proximity coupled feed. We have chosen to compare co-axial feed and microstrip inset feed due to the advantage that it can be easily fabricated and simplicity in modelling as well as impedance matching. The objective of this paper is to design a rectangular microstrip patch antenna which operates in C-band at 5.2 GHz. Microstrip antennas are most suited for aerospace and mobile applications etc. They can be designed in variety of shapes. Therefore, method of moments based IE3D software is used to design a Microstrip Patch Antenna with enhanced gain and bandwidth. IE3D is an integrated full-wave electromagnetic simulation and optimization package for the analysis and design of 3D and planar microwave circuits. The IE3D has become the most versatile, easy to use, efficient and accurate electromagnetic simulation tool. It computes most of the useful quantities of interest such as radiation pattern, input impedance and gain etc. The microstrip patch antenna is designed and simulated using high frequency simulation software IE3D and it is designed to operate in C-band frequency range (4GHz-8GHz). These antennas are designed using RT-duroid dielectric substrate with the permittivity εr=2.2. In this analysis, we have compared the antenna parameters such as gain, impedance, reflection coefficient, VSWR and further the performance of these two feed techniques discussed. The antenna has been designed for the range 5-6 GHz; hence this antenna is highly suitable for C-band applications wimax applications, and other wireless systems.

Archu S. Vijay ; M Prabhakar
Electrical Engineering
Year: 2015, Volume:1, Issue : 12
Pages: 601 - 606
This paper deals with various transformerless PV Inverter topologies with MPPT and low leakage current. Transformerless inverters are widely used in grid-tied photovoltaic (PV) generation systems, due to the benefits of achieving high efficiency and low cost. For PV panels, due to parasitic capacitance there will be some leakage current. So there is a strong trend in the photovoltaic inverter technology to use transformerless topologies in order to acquire higher efficiencies combining with very low ground leakage current. The major task of this work is the investigation and verification of transformerless topologies and control strategies to minimize the leakage current of PV inverter topologies in order to comply with the standard requirements and make them safe for human interaction. Simulations were done using Matlab/Simulink. High conversion efficiency and low leakage current are demonstrated.
