Optical Transparent single crystals of Pb2+ doped Potassium acid Phthalate at different proportions were grown in aqueous solution by slow evaporation method at room temperature. The characterization of functional groups in the crystal lattice and optical absorption studies were done by FTIR and UV visible spectrophotometer.
Stir cast Al 7075/20%SiCp composites were subjected to compression testing at strain rates and temperatures ranging from 0.001 to 1.0 s−1 and from 300 to 500°C respectively. The associated microstructural transformations and instability phenomena were studied by observations of the optical electron microscope. The power dissipation efficiency and instability parameter were calculated by using the...
Mechanical component design by safety factors using nominal values without considering uncertainties may lead to designs that are unsafe, or too conservative and thus not efficient. Design of a helical compression spring is one of complex and time consuming design procedure. This paper presents development of mathematical models to predict the outer diameter of a typical helical spring. This paper...
This paper presents the modeling and simulation of a dynamic voltage restorer as a voltage sag/swell mitigation device in electrical power distribution networks. The dynamic voltage restorer, with its excellent dynamic capabilities, when installed between the supply and a critical load feeder, can compensate for voltage sags/swell, restoring line voltage to its nominal value within few milliseconds...
This paper aims at designing an oxygen level monitoring technique in an oxygen cylinder. The amount of oxygen present inside the oxygen cylinder is very vital information when such cylinder is in use for supply of oxygen to a critical patient. The amount of oxygen present inside the cylinder is measured by the pressure at the outlet nozzle. The pressure is measured using a high precision MEMS Pressure...
Thin-walled tubes are used as energy absorbing elements in various applications. The circular tube is a famous energy absorber because an axisymmetric structure dissipates energy equally around its surface leading to uniform force distribution. In the present study, the energy absorption characteristics of end formed aluminium AA6061 alloy circular tubes have been studied. Experiments were conducted...
The Importance of PAS (Performance appraisal System) are emphasizing asBig Public sector banks, Medium Public sector banks and Small Public sector banks. It is only through proper implementation of Performance Management System, quality workforce can be retained. Usually a separate Independent Agency is appointed to evaluate the performance of the employees which is usually carried out online. The...
This paper will describe the signal processing and channel enhancement using MIMO technology In order to have flexibility in transmission system, wireless systems are always considered better as compared to wired channel. Having known the drawbacks of the Single Input Single Output system, and having computed the advantages of Multiple Input Multiple Out, several techniques have been developed to...
This paper presents a low peak power consumption BIST based on genetic algorithm (GA) is applied for viterbi decoder error detection and correction, denoted by GAITPGEDC. This method aims at reducing the changes between successive test pattern. Here m-1 test vectors are inserted between two successive n-bit generated by linear feedback shift registers (LFSR), where m and elements of group were optimized...
Internet congestion occurs when the aggregate demand for a resource (e.g., link bandwidth) exceeds the available capacity of the resource. TCP is used as a Transport Protocol for most of the applications on the Internet and is also responsible for adjusting to network congestion dynamically. TCPs congestion control mechanism is insufficient in a wireless environment because packet loss does not always...
This paper presents the analysis of Load Frequency Control (LFC) of a two-area hydrothermal system under deregulated environment by considering Adaptive Neuro-Fuzzy Inference System (ANFIS). Fixed gain controllers for LFC are designed at nominal operating conditions and fail to provide best control performance over a wide range of operating conditions. So, in order to keep system performance near...
This paper addresses optimization in cutting parameters to obtain minimum surface roughness using multiple metamodeling techniques like Design of Experiments (DOE), Response Surface Methodology (RSM) and Fuzzy inference system. The second order mathematical models in terms of machining parameters were developed for surface roughness prediction using RSM on the basis of experimental results. The model...
This paper reports the benefits of Probabilistic language modeling in template messaging domain. Through a Statistical Machine Translation (SMT) sentences written with short forms, misspelled words and chatting slang can be corrected. Given a source-language (e.g., Short message) sentence, the problem of machine translation is to automatically produce a target-language (e.g., Long form English) translation,...
There is broad consensus that Indian educational industry employers must do more to support and develop their staff within healthy and positive environments. Turning the corner on educational human resource challenges requires nothing short of cultural transformation. Just as in other industries, the transformational journey is step-by-step. The goal: building a high-trust culture that encourages...
This paper presents a novel formation control technique of a group of differentially driven wheeled mobile robots employing artificial potential field based navigation and leader-follower formation control scheme. In the proposed method, the leader robot of the group determines its path of navigation by an artificial potential field and the other robots in the group follow the leader maintaining a...
Clock distribution network forms an integral part of any digital circuit. It consumes a large part of the total circuit power, which is not desirable. Different techniques are employed up till now to reduce the clock power. In this paper we have demonstrated how clock power can be reduced significantly by distributing it at reduced supply voltage. The clock distribution network is designed and simulated...
This study aims to determine the runoff depth using NRCS-CN method with Remote sensing and Geographical Information System (GIS) and the effect of slope on runoff generation. This study was carried out in Bamhani catchment located in Mandla district of Madhya Pradesh. The USDA NRCS- CN method was applied for estimating the runoff depth in the Bamhani catchment. Soil map, Land Use and slope map were...
In this paper, the operation of a Fuzzy Logic Controller with PSS controller is analysed in simulink environment. The development of a Fuzzy Controller with power system stabilizer in order to maintain stability and enhance the performance of a power system is described widely.

In this paper, the SAZZ Converter with Soft Switching technique is applied to the Fuel Cell System to improve the output voltage to desired value. The Output voltage of this converter is obtained as a DC Voltage, which is connected to an impedance network, to remove the ripples present in the circuit. A 3 phase inverter operating at 180 degree mode is connected with the system. Filtering technique...
In this paper, a new procedure called fuzzy determinant procedure is used to solve a fuzzy non-zero sum bi-matrix game. The optimal fuzzy strategies for the players can also be found using the proposed method. The required definitions are also given. The method is clearly explained by means of a numerical example.
