The main aim of this research work is to analyze and develop voltage up gradation procedure model for effective & economic power distribution in urban and suburban area. Voltage up gradation from 6.6 KV to 11 KV of the distribution power system network has been considered for the proposed research work. Electric power consumption has been increasing uninterruptedly, being this increase specially accelerated in the last few years. Nowadays electric lines are saturated; they are reaching critical values of ampere capacity and sag. Therefore, building new lines has been necessary to provide the ever increasing consumption. The difficulty to find new corridors to construct new distribution lines, underground cables is increasing in cities, industrial areas and in many cases it is simply impossible. The construction of new electric lines is increasing difficulty, thus there is a need to look at alternatives that increases the power transfer capacity. Voltage up gradation of the existing electric cables/lines of the distribution system is the most viable solution and it stresses on the savings of power due to a reduction in system losses when the voltage is high. The proposed research work is to develop and analyze voltage up gradation procedures and protocols for converting 6.6 KV network into 11 KV network in a distributed system. It also takes into account the expenses incurred in the process and the various other important constraints.

Organic Light Emitting Diodes (OLED) are solid state devices having a great potential for commercial and industrial lighting applications. They are flexible and have an added advantage of not containing any toxic materials and hence are highly sustainable. In this paper, a comparative evaluation is done on the performance of OLED with its popular counterpart Light Emitting Diodes (LED) in terms of luminous emission, efficacy as well as coefficient of utilization (CU) on the basis of similar size and input wattage using the softwares MATLAB and Setfos. The choice of samples were chosen from a wide variety of products that are available in Illuminating Engineering Society (IES) databases. It is observed that, though OLED lags behind LED in terms of magnitude of luminous intensity and efficacy, it has a better CU and is observed to cover a wider area for illumination, making it suitable for luminaire systems near the work plane or even in emergency lighting systems. As OLED is still in the development phase, there are many lighting design softwares that do not have OLED lighting systems in their catalogue, hence MATLAB is a good candidate for analyzing the performance characteristics of OLED presently. © 2016 IEEE.

The weld quality is generally controlled by the welding parameters. In gas metal arc welding process, the welding parameters are inter related and the adjustment of one parameter may affect another parameter and hence it is considered as a non-linear process. The non-linear nature of the welding system makes it difficult to implement a conventional control method. Fuzzy logic control is an attractive alternative approach. The performance of fuzzy controller will be very much dependent on the knowledge provided to the system. Therefore in recent years, more research has been devoted to augment the approximate reasoning method of fuzzy systems with genetic algorithms. In the present work, genetic algorithm tuned conventional controller is implemented for gas metal arc welding system. Its performance is compared with that of genetic algorithm based fuzzy logic controller. © 2013 - IOS Press and the authors. All rights reserved.

The primary purpose of this paper is to provide reachability between applications running on end hosts in MIPv4-MIPv6 coexistence phase. In this paper, we describe how to compute the reachability which a network, in this case MIPv4-MIPv6, provides from a snapshot of the configuration state from each of the routers. Reachability analysis of any network would be valuable for verifying the intent of the network designer, troubleshooting reachability problems, and performing 'what-if' analysis of failure scenarios. © 2013 IEEE.

Parkinson's disease has affected over 6.3 million people across the globe. It is estimated that by 2030, the number would rise to 9 million. Almost twenty percent of the people still remain undiagnosed. Parkinson's is the second most common neurodegenerative disease after Alzheimer's. It not only claims the lives of the patients suffering from it but also adversely impacts the lives of their loved ones. A lot of research is being conducted to find modern medical techniques to tackle the ill effects of the disease. Monitoring the progression of the disease plays a vital role in controlling its various symptoms. Non-conventional ways of monitoring PD (Parkinson's Disease) provide an edge over the existing techniques as it reduces the financial burden and also limits the number of clinical visits required for it. In this research paper, we aim to build a predictive model that accurately predicts the UPDRS (Unified Parkinson's Disease Rating Scale) of patients using the data collected through noninvasive speech tests. The research hopes to propose a more efficient technique to monitor Parkinson's disease leading to beneficial treatment of the patients. © 2016 IEEE.

VLSI trends are in focus to reducing gate sizes for miniaturization of circuits to be on par with the Moore's law which states that the number of transistors in a unit area doubles every 18 months. To make this possible, transistor gate sizes must be reduced. More shrinkage of gate size leads to short channel and leakage effects which are undesirable making CMOS impossible to use beyond 22nm. To replace CMOS in circuits, another type of Field Effect Transistor called FINFETs are deployed. They are multigate devices and so, they control leakage and other short channel effects. They are more efficient in performance than CMOS, but because of multigate, the parasitic resistance and capacitance is more than that of CMOS. This limits its analog performance. This paper focuses on reduction of parasitic capacitance of 20nm FINFET by optimizing the gate spacer material used. The simulations are done on Synopsys TCAD tools and finally the circuits using the optimized FETs are simulated using HSPICE to measure parameters like delay, power, etc. © 2015 IEEE.

Environmentally Sustainable Design is in accordance with the concept of sustainability to design objects and built environment achieving a balance that causes no overall net environmental burden. At a time when global warming is proceeding at a rate, unprecedented in the past 1,300 years, we not only need to switch to greener energy sources and reduce consumption on the whole, but also make provision for the victims of future calamities that are inevitable due to irreversible environmental damage. This paper talks about creating an ecological balance in natural and manmade ecosystems. The need for Environmentally Sustainable Energy as well as the concept and its principles has been explained. A case study was taken up on the LILYPAD Project by architect Vincent Callebaut to showcase an excellent example of an environmentally sustainable design concept for future climatic refugees. The prototype is termed as an "auto sufficient amphibious city" and takes up the challenges launched by the OECD namely climate, biodiversity, water and health. The research also states how we can incorporate the idea of living symbiotically with nature in the construction of future homes with the implementation of one such concept i.e. Passivhaus standards. This paper aims to create awareness about environmental responsibility and how the use of environmentally sustainable design can help us realize this practically. All structures must be constructed with the aim of making them as energy efficient as possible by implementing the Passivhaus Principles and many such standards that can reduce our energy consumption and emission.

This paper aims at Fiber Reinforced Panel or FRP mold and panel manufacturing of body panel and driver seat for a Formula Society of Automotive Engineers or FSAE racecar. The competition involves designing a Formula 1 type car that lays the standards for a high performance-racing car [1]. This calls for a high Power: Weight ratio. The rules of the competition ensure a mandatory use of an air restrictor with an engine of a maximum capacity of 600cc to reduce the power of the engines [2]. Hence, to compensate for the loss of power the target now shifts to minimizing the car's weight without compromising the strength. The body panel and driver's seat are two most valuable parts as the first adds elegance and aerodynamics to the car while the latter makes it comfortable for the driver to drive the car under high lateral load shifts. Weight reduction in this area is easier as strength is not the dominating factor. It is preferred because of its low cost, good strength, flexibility and elegance after finishing. To make the fiberglass product of a particular shape, a mold of the same shape is needed. For a smooth outer surface of the product, as in the case of the car body panel, an inside-out or negative mold needs to be made. The mold can be constructed by many ways ranging from using chicken wires and clay to using the MDF (medium density fiberboard), to achieve more accuracy and a smoother surface to obtain a better product.
