ABSTRACT The design of pressure vessels for operating at very high pressure is a complex problem. The pressure vessels used in  wide  applications  such  as  in  thermal  and  nuclear  power plants, in chemical industries, in space and ocean depths, in hydraulic units of aircrafts  and  fluid  supply  systems  in  industries. The pressure vessels have different […]

ABSTRACT Fast depleting natural resources, huge consumption of energy, and environmental hazards involved in the production of cement has inspired for searching the substitution by other material with similar material, especially in developing countries. Cement is widely noted to be most expensive constituents of concrete. The objective of is study is to investigate the mechanical […]

ABSTRACT The massive growth of interconnected power systems due to increasing demand of electrical energy has given rise to numerous challenges. In these situations, Flexible Alternating Current Transmission System (FACTS) controllers This paper discusses the transient stability enhancement by use of SSSC FACTS controller when applied in Transient Stability Enhancement (TSE) in a dynamic IEEE […]

ABSTRACT SNTs (surrounding-gate nanowire transistors) are good candidates to implement low power electronic devices. They provide full gate control over the channel and minimize short channel effects. Design of a high-speed opamp is presented in this paper. It consists of two amplifying stages and an output buffer and is frequency compensated for stable operation. Transistors […]

ABSTRACT In this paper presents a new novel reaching law for sliding mode controlled DC-DC buck converter. The proposed novel reaching law can dynamically adapt to the parameter variations of the controlled system, which allows chattering reduction on control input while maintain high tracking performance of the controller. Chattering analysis presented for both traditional and […]

ABSTRACT The latest mobile communications is two types of ad hoc networks are introduced; one is Mobile Ad Hoc Network (MANET) and second one is Vehicular Ad Hoc Network (VANET).VANET is based on IEEE 802.11b wireless standard. This helps to communicate vehicle to vehicle and vehicle to roadside communications. According to Federal Communications Commission (FCC)[1] […]

ABSTRACT Railway wayside signaling is a system used to control railway traffic safely, essentially to prevent trains from colliding. Therefore it is required to have a reliable power supply to keep a healthy and sustainable rail network. The methodology to develop the power supply presented in this paper involves study and implementation of power factor […]

ABSTRACT The aim of this study is to numerically simulate the continuous casting products using commercial CFD software ANSYS FLUENT. CFD code only give numerical results on casting like fill time, conversion of liquid to solid phase and many more, but it is not show relation among factors and their responses, so in this study […]

ABSTRACT The present investigation is aimed to prepare blends comprising of Ethylene Propylene Diene Monomer (EPDM) and Linear Low Density Polyethylene (LLDPE) with the help of two roll mill by melt blending process at various blend ratios. The effect of LLDPE on mechanical and thermal properties of the developed blends has been investigated. The results […]

ABSTRACT Heat transfer using natural convection and fluid flow is an important phenomenon in daily life and engineering applications such as HVAC systems of building, harvesting energy using non-conventional energy sources, extraction of heat from electronic equipment and cooling technologies integrated in computer systems. The present study investigates about the two experiments: (1) Heat transfer […]
