Prospects of Tunnel Field Effect Transistor
Jyoti and Isha Sharma

Abstract
Tunnel Field Effect Transistor (TFET) is considered as a future transistor option in ultra-low power applications because of its steep sub-threshold slope prospect. In this paper, authors are reviewing TFET’s prospects such as the device structure, operating principle, various configurations and its I-V characteristics. The comparison between the I-V characteristics of TFET and MOSFET has been studied. Heterojunction TFET generally gives the better drive current than homojunction TFET because the source to channel tunnel barrier height is lower in heterojunction TFETs which allows them to attain steeper sub-threshold slope and improved drive current. However, the ION/IOFF ratio of TFET is lower than that of MOSFET which can be further improved by using lower bandgap channel material, by creating higher doping levels and abrupt doping profiles.

Homojunction InGaAs Tunnel Field Effect Transistor
Jyoti and Isha Sharma

Abstract
In this paper, a study of the impact of double gate In0.53Ga0.47As channel material, gate structure, work function and high-k dielectric HfO2 for gate is analyzed by using Cogenda Visual TCAD tool. The simulation study showed the better subthreshold swing, lower leakage current and higher ION/IOFF ratio than the conventional MOSFET at room temperature. Further study showed the improvement in ION for the double gate structure. The various performance parameters namely threshold voltage, subthreshold swing, Drain Induced Barrier Lowering (DIBL) and ON current to OFF current ratio are also investigated.

A Review on Engine Valve Train and Its Effect on Cam Shaft
Avinash, Kuldeep Malik, Jagdeep Sangwan

Abstract
The major role of the valvetrain is ensure the gases exchange process for all engine speed. The valve gear mechanism of I.C. engine consist on the parts which actuate the inlet and exhaust valves at required time w. r. t. the position of piston and crankshaft. The gases exchange process influences engine for good functioning, a kinematic and the dynamic analysis are required for engine valve train. The vibration and acoustic behaviour of the internal combustion engine is highly complex. The engine speed is most important value in valve train dynamics. A flexible multibody model can be used investigate the dynamic behaviour for a valve train by considering interactions between valve train Components such as the model includes a flexible camshaft, spring & rocker arm.

A Review on Powder Metallurgy Techniques
Mohit Kumar, Kuldeep Malik, Jagdeep Sangwan

Abstract
Joining of Dissimilar metals has a wide range of applications in linking joints like electronic connectors, due to its physical and mechanical properties. Joining of disparate metals is often more complex task than joining the same. In this present work powder brazing technique is chosen as a technique for joining of Cu-SS, Cu-Fe, and Cu-Ni. Powder brazing of dissimilar metals has advantages over conventional joining techniques which does not involve melting of the base metal and thus avoids the problems associated with it, variation in thermo-physical properties and leads to formation of high amount of undesirable compounds as a result high joint strength cannot be achieved.

An Analysis on Software Cost Estimation Techniques
Jyoti Sharma, Kulvinder Singh

Abstract
The estimation of the software cost remains one of the most challenging problems in software engineering; as a preliminary estimate of cost includes many elements of uncertainty. Reliable and early estimates are difficult to obtain because of the lack of the detailed information about the future system at an early stage. However, the early estimates are really important when bidding for a contract or determining whether a project is feasible in terms of cost-benefit analysis. Estimators often rely on their past experiences for the prediction of effort for software projects. The fundamental factors that are contributing towards inaccuracy of the cost estimation process are imprecise and drifting requirements, information not readily available on past projects, and the methods that were developed and trained on specific data. In this proposed work we have developed a software cost estimation tool that helps commercial software-development organizations to effectively and quantitatively measure and analyze the software metrics based upon the function requirements, operational constraints and organization’s capability to handle a project. This cost estimation tool is a fusion implementation or an essence of certain software measurement and estimation techniques that help a software organization to evaluate and analyze fundamental software metrics such as complexity, time, effort, and cost all of which are essential to improving turnaround time and attaining organizational maturity. The new cost estimation method is proposed for the iterative software development projects. The use case technique is implemented per iteration for the specification of the software requirements. COCOMO II and Function Point were used to compute the effort required for successive iterations. We also computed the magnitude of relative error for successive iterations. We tested the proposed method on student projects in order to illustrate its usefulness.
