Abstract: Analysis of induction motor is much essential to find out utilization index of a motor for better performance. When we analyse an efficiency of an induction motor we need to acquire many parameters like voltage, current, KW, speed, and torque from motors. All the above said parameters must be acquired at fastest speed to present an instantaneous efficiency indication.

Abstract: Insuring a comfortable ride for passengers, in a vehicle, is based on external disturbances (e.g. road bumps or holes) that can affect the vehicle. The objective of this project is to design controllers to eliminate or reject the effect of the external disturbances (possibly in impulse form or infinite energy) on the performance of the full-vehicle suspension system in order also to reduce heave, pitch and roll acceleration. Three types of controllers were designed for this system. The design controllers are a state feedback controller, a H2 and a H∞ controller by using the Linear Matrix Inequality (LMI) technique. Simulation results are given to illustrate the performance of the proposed controllers.

Abstract: As power systems become more complex and heavily loaded, voltage stability becomes an increasing serious problem. Voltage instability problems increasing day by day because of demand increase. It is very important to analyze the power system with respect to voltage stability. At present, wind power energy is increasingly penetrating electrical grids. This penetration is mainly driven by better wind technologies.

Abstract: We use high KVA rated transformers in industries to supply high transient state current, however the steady state current is low which lead to high primary coil losses in the transformer. As a substitute we therefore present the application of super capacitors in industries to avoid voltage dip and the usage of high VA rated transformers for the sake of high transient state current hence saving the primary coil losses and reducing the size of the supporting equipment. The super-capacitor also contributes to the improvement of power factor, regulated voltage supply during steady-state and reduces harmonics in the supply. This paper has the detailed explanation of the application of super-capacitor as an additional source and has a diagram of the proposed super-capacitor circuit.

Abstract: DC-DC converter topologies, the controllable switches are operated in switch mode where they are required to turn the entire load current on and off during each switching cycle. This work proposes a high-efficiency positive buck– boost converter with mode-select circuits and feed-forward techniques. Four power transistors produce more conduction and more switching losses when the positive and negative buck–boost converter operates in buck–boost mode.

Abstract: DC-DC converters are widely used in application such as computer peripheral power supplies, car auxiliary power supplies and medical equipment's. Positive output elementary Luo converter performs the conversion from positive source voltage to positive load voltage. Due to the time- varying and switching nature of the power electronic converters, their dynamic behavior is highly non-linear. Conventional controllers are incapable of providing good dynamic performance and hence optimized techniques have been developed to tune the PI parameter. In this work, Particle Swarm Optimization (PSO) is developed for PI optimization. Simulation results show that the performances of PSO-PI controllers are better than those obtained by the classical ZN-PI controller.
Keywords: PI controller, DC-DC converter, positive elementary Luo converter, particle swarm optimization and soft computing technique.

Abstract: Rudimentary work on waveguides for long-range communication originally started in 1964 for wideband signals. Initially, the advancements in this domain suffered from significant challenges including dielectric losses, attenuation, inter/intra-model dispersion and micro/macro band losses. It was not until 1980s that optical communication emerged as a feasible mean of communication. However, the medium still suffered from major drawbacks. For instance, there were no optical amplifiers at that time. Moreover, the nodes/repeaters had re-amplification, retiming and reshaping (3R) regeneration processes that were done in the electrical domain which is commonly termed as the optical-electrical-optical (O-E-O) conversions. This resulted in a transformation from optical to electrical and back to optical domain which had its own performance bottlenecks. Despite these shortcomings, optical communication has seen increasing modifications and innovations that are improving speed, the core or the access, and the optical burst switching mechanisms (Pedrola et al. 2011).

Abstract: The last decade has seen an explosion in the use of the Internet. Many more people are logging on the Internet, and Internet access has also spread to areas that have never had a telephone connection before. This growth in number of people accessing the Internet and the geographical spread has served to act as an impetus to the development of new applications on the Internet. The increased reliance on the Internet for a wide range of functionalities has given rise to the phenomenon of convergence. Convergence is the phenomenon of deploying various services, especially multimedia services, over traditional networks. Convergence is blocked by many problems that are caused by the inherent nature of the network expected to support these services. This research attempts to examine the state of integration of multimedia signals and their transmission over IP networks.

Abstract: Remote Monitoring, and Control is one of the most important and necessary criteria for increasing production and process plant availability. There is lot of development in industry and the requirement for industrial monitoring system is getting higher. System should be able to acquire, save, analyze, and process real time data. It is also required controlling particular machines, to change related environment factors and monitoring in long distance so that it realizes modern, intelligent, and accurate control. We can achieve these advantages by the substitution of embedded ARM processor to realize data acquisition and control (DACS). This DACS system measures the remote signals and controls the remote devices through reliable protocols and communication network as a web server. In addition of that a GSM Mobile Communication will help to providing information about related parameter to the system when web server is not available to client.

Abstract: The aim of this paper is to implement optimum controller for a spherical tank. The objective of the controller is to maintain the level inside the process tank in a desired value. The real time implementation of the process is designed and implemented in MATLAB using data acquisition module. The identified model is in the form of first order plus delay time (FOPDT) process. Controller design is compared based on conventional Proportional Integral Derivative (PID) with Internal Model Control (IMC) based on Skogestad's settings in terms of performance indices. Out of the control algorithms SIMC outperforms in no overshoot, faster settling time, better set point tracking and produces lower performance indices.

Abstract: In this paper, the performance of Long term evolution (LTE) based on orthogonal frequency-division multiple access (OFDMA) is investigated which uses multiple input, multiple output technique (MIMO). This paper gives an peak to power average ratio (PAPR) analysis of MIMO performance along with OFDMA modulation using Matlab of the next generation telecommunication network LTE 3rd Generation partnership project (3GPP). The downlink is based on orthogonal frequency-division multiple access at the physical layer, while the uplink is based on single carrier frequency-division multiple access. The PAPR reduction to achieve a low clipping rate which is actually done in SC-FDMA, as clipping is low the efficiency is also low which provide great benefit in power consumption. Thus LTE can transmit a packet efficiently with low latency and as well as without transmission error. This paper gives the comparison of LTE release 8 and LTE release 10.It provides communication with a terminal, moving up to 500 km/h.
Index Terms: 3GPP, LTE , MIMO, PAPR, SC-FDMA.

Abstract: Now a days live video streaming becomes more popular in the residential market. As the number of users increases the requirement of bandwidth also increases. The quality of video is affected due to the limitation of bandwidth. So far, protocol RTSP has been used for the transmission that supports retrieval of media from server and also supports recording of conference. In this paper, we propose an Enhanced Media Codec protocol for the transmission of high quality video without pixel drops according to the resolution size of the customer's monitor.
