Abstract: Water quality in power plant is the main factor of equipment reliability. Standard water quality can assure performance of equipment and minimize equipment defact especially from corrosion. In Block 5 UP Muara Tawar, water is used to producing steam from HRSG. Actually pH for HP drum is 30% above the upper limit. To overcome this problem, it is needed to do some adjustment with the method as follows: data collection from process information system, brainstorming with operation, engineering and instrumentation to improve quality of water for short and long term period of operation, perform temporary corrective maintenance by Operate CBD in higher opening Operate phospate........

Abstract: General artificial neural network (ANN) analysis has been applied to optimize the lower and upper frequency limits of cutoff region of switchable microstrip circular patch antenna printed on ferrite (LiTiZn) substrate in the X-band range. The ferrite substrate offered numbers of novel magnetic and electrical characteristics including switchable and polarized radiations from a microstrip antenna with DC magnetic biasing. For particular frequency limits most of the power will be converted into mechanical waves and very little radiates into air. Under such condition the antenna become switch off, in the sense of effectively absence as radiator. In this work Radial Basis Function (RBF) networks has been applied in ANN models. Synthesis has been defined as the forward side and then analysis as the reverse side of the problem. In the RBF network, the spread value has been chosen as 0.01, which gives the best accuracy...................

Abstract: Power distribution system is a vital system and considered as one of the most important subsystem of the whole satellite. This paper basically discusses the design of the power distribution module (PDM) of a low earth orbit small satellite. The designed PDM draws24 Volt unregulated power from the Power Control Distribution Unit battery charge regulator module (PCDU-BCR)and then provides regulated 3.3 Volt, 5 Volt, 12 Volt and unregulated 24 Volt to the satellite subsystems. The PDM implements current sensing, current limiting, switching and protection of the loads.Moreover the PDM design fulfils internal redundancy to achieve the required reliability.The switching algorithms............

Abstract: The ever increasing demand for the Electrical energy has made the mankind to turn towards renewable energy sources. Photovoltaic (PV) is one of the renewable energy source. For effective and efficient utilization of the SPV panel a DC-DC converter interface required. The problem in using high frequency converter interface is the resultant high frequency ripple interaction with the SPV system. In this work, an interleaved boost converter (IBC) is considered to reduce the ripple. Our finding is that IBC fed by a SPV panel reduces this ripple to a greater extent. IBC also has a faster transient response as compared to conventional boost converters with reduced ripple contents...............

Abstract: Bipolar Heterojunction Transistors (HBTs) have proved to be excellent devices for applications in microwave telecommunication systems. In this study, the aim is to optimize and to improve the InP / InGaAs HBT electrical performances. For this, we used the software TCAD-Silvaco (Technology Computer-Aided Design) which allows the simulation of the electrical and physical behavior of electronic components. We worked with the interactive tool DeckBuild to define the simulation program, and we used the device structure editor DevEDIT to design the InP/InGaAs HBT according to its technological characteristics (dimension, doping, meshing ...), and also the device simulator...............

Abstract: In progress of a product, programming mistakes are unavoidable. For expectation of the
imperfections in a product, we need to create programming unwavering quality development models to
investigate the items and to anticipate them. A similar development model can't be utilized for all the
information. Subsequently different programming unwavering quality development models are utilized for which
the information is isolated into a few sections and distinctive development models are utilized for every datum
part. Later they are recombined. By consolidating all the conventional unwavering quality development models
we get a multistage dependability.......

Abstract: This research paper proposes the Secure Web Application Development and SELinux based
distributed Trusted Operating System for maintaining the security aspect in web applications. Unlike the
conventional methods of adding more and more security layers at the kernel level, in this proposed design, we
are suggesting two subsystems like object manager and security server. This model allows system
administrators to skip or disable some unnecessary security checks in SELinux trusted operating systems
through which they can effectively balance their performance needs without compromising the security of the
system. This paper suggests UML 2.0 based class-based software development and the integration of security
engineering into a model-driven software development.

Abstract: In this article, a 13-level single phase cascaded hybrid multilevel inverter with a minimal number of live switches is introduced. In this concept, a switched capacitor (SC) system is intended. The number of output levels is determined by the number of switched capacitor cells. This circuit's design is fairly straightforward, and it is simple to advance it. The gate drive circuits are simplified when the number of live switches is reduced, and power losses are analysed. Using MATLAB/SIMULINK, a 13-level single phase cascaded hybrid multilevel inverter model is created, along with targeted modulation schemes. A single phase induction is driven when this multilevel inverter has been evaluated.............
