Gait analysis is currently the most widely used technique for analyzing the walking pattern of patients and detecting the problems. Besides analysing the gait cycle of human being, another important application is to check the reliability and compatibility of prosthetic legs (check the flexion and extension of prosthetic legs). It is used for detecting the different problems related to posture and movement in physiotherapy science. The main aim of our research was to make this technique easily available to everyone at low cost while maintaining the reliability and efficiency. The technique which we followed focused on measuring the different gait parameters (i.e. angle of different joints) by using gyro sensors. We mounted 3 gyro sensors at different joint positions of leg (ankle, knee and hip) and took readings from those gyro sensors using I2C communication protocol. We used MSP430F5257 as our central processor. After testing different samples and analysing the data available we found our sensor reliable and quite accurate. This strongly supports the use of our Gyro based system for analyzing Gait cycle for medical usage.

A comparator is the essential building block of any analog-to-digital circuit. They generally are the decision-making circuits that play a key role in the analog to digital conversion; hence the accuracy and speed are the characteristics that are considered. Dynamic comparators are thus most widely used. This paper puts forth the design of a latch-based comparator which has very less delay, high speed, low area and less offset voltage, in comparison to the conventional comparators. The power dissipation is also less of the proposed circuit. The design and analysis (simulation) has been done using Cadence tool in 90-nm CMOS technology.

Renewable energy and its applications need to get more attention and research. Wind energy is still in the queue of development and research. In this paper it is proposed about a wind turbine to convert wind energy into electrical energy. Electricity will be generated by installing wind turbines along railway tracks, so that the gust of wind generated by running train can be used to rotate the blades of proposed wind turbine and generated power will be used to lighten up the local houses and guard house.

The role of power system is to supply the power to the various load center. Today's power system is designed to operate effectively and efficiently. In earlier years, Electric power system was small and localized. In order to improve stability of the system, real and reactive power compensation in the transmission line is important. This paper describes theory & modeling of one of the Flexible Alternating Current Transmission System (FACTS) devices, called as Static Synchronous Series Compensator (SSSC). Generally SSSC is connected to the bus through Voltage Source Inverter (VSI), but it is having demerits like limited output voltage, restriction on simultaneous switching of upper & lower switches etc. All these issues are sort out if Z source inverter (ZSI) is used instead of VSI. This paper presents modeling of SSSC based on Z - Source Inverter (ZSI) with SPWM technique. The system's behavior with and without SSSC have been studied.

Current prediction is a vital and an important aspect of power metering and control systems. Not only does it help avoid overloading shutdown situations but can also decide the rating of certain switchgear. In this paper both normal and fault condition current prediction is done using Artificial Neural Network (ANN). Performance of the ANN largely depends on how well its weights are trained. Learning algorithms used for this purpose should be robust and have the lowest possible margin of error between desired and actual outputs. We have done a comparison of two different learning algorithms - Back Propagation (BP) and particle swarm optimization (PSO) for both normal and fault current prediction in 33 kV feeders at the BSES Yamuna Power Ltd. substation (New Delhi) connected to the Northern grid. The performance index in both cases is analyzed and then compared. The results obtained show that PSO, being a group based learning algorithm is the better of the two.

Optimal placement of FACTS devices in a power transmission network is of great importance for the effective utilization of transmission network. Thyristor Controlled Series Compensator (TCSC) - a series FACTs device can be used to reduce the power flows in heavily loaded transmission lines resulting in an increased loadability, low system loss, power congestion management and stability improvement. In this work three methods have been suggested to find the optimal location and optimum size of TCSC to increase the power transfer capability of a transmission system. A variable reactance model of TCSC under steady state condition is used. Proposed approach is tested for locating TCSC in an IEEE 6 bus system. A comparison of three methods, namely the total Real Power Loss minimization based sensitivity index method, Real Power Flows minimization based sensitivity index method and the total Reactive Power Loss minimization based Sensitivity Index method has been presented with appropriate discussion.

This paper addresses the decentralized proportional - integral (PI) controller design for two-input, and two-output (TITO) processes. The controller design is based on the nondimensional analysis. Selection of proper controller is difficult task for multivariable processes because of the interacting dynamic behavior of the process variables in which change in one manipulated variable affects the other controlled variables. In this study, decentralized PI controller with decoupler is selected and designed on the basis of process transfer function matrix and decoupler matrix. Tuned parameters of PI controller are found by non-dimensional tuning (NDT) method (2006). For better understanding, MATLAB simulation results are presented. For showing effective performance of NDT method, the results are compared with Astrom-Hagglund tuning rule (1995), Fruehauf et al. tuning rule (1993) and biggest log modulus tuning (BLT) method (1986).

In industry field, common A/D converter chips are widely used for low-speed analog data acquisition. Most of common A/D converter chips are not fit for the requirements of high-speed vary analog signal. This paper presents a high-speed data acquisition system based on LVDT. Design, simulation, implementation and testing of an inductive displacement sensor based on a Linear Variable Differential Transformer (LVDT) controlled by a single chip electronic module with microcontroller. LVDT device is widely used systems for measuring physical quantities like displacement, force or pressure. The design is based on PAC-1.0 card is proposed for LVDT sensor detection and realized the high-speed digital data acquisition of multichannel sensor digital signals in the method of software polling mode. This paper aims to present an experimental device, which measures the displacement of inner diameter and outer diameter. This displacement is measured with a very high degree of accuracy, by means of inductive probe. The probe and its associated electronics system convert the displacement into a proportional voltage. The measured results of application indicate that the measurement precision can reaches 0.1 μm, and 1 μm. This system has good commonality as well as extensibility.

The distribution losses in the distribution network causes disproportion in the voltage profile and the power balance in the concerned power system. In order to reduce distribution losses in the network, the load factor of the connected power system has to be improved through load management. After studying the load profile of Tezpur University, the appropriate load replacement and load scheduling has been done in order to achieve improvement in the load factor for the distribution system of Tezpur University.

We assume a wireless sensor network (WSN) having differently spaced nodes or relays at every place, and a two step transition of information from source to relay (nodes) and from nodes to destination or fusion center (FC). We will introduce relay selection schemes that attempt to optimize the transmission of data. This scheme selects a group of relays that listens the information and transmits to the destination. By using this scheme we will achieve minimum number of relays in active state and also minimizes the outage probability and transmitted minimum expected number of bits by the network and making the efficient network system.
