The majority voter plays the core role in the Triple-modular redundancy (TMR) based fault tolerant scheme. This work targets to implement a novel fault tolerant structure of the majority voter for the implementation of TMR using Quantum-dot cellular automata (QCA), a viable alternative nanotechnology to current CMOS VLSI. The proposed fault-tolerant voter circuit itself can tolerate a fault and give...
In the present paper, a PC based position control system of a PMDC motor has been designed by utilizing MATLAB based PID controller and Data Acquisition System, in order to control the process variable to achieve the most efficient control in the plant operation. The final calibration data of angular position of PMDC motor are reported in the paper, which reveal the linearity and reliability of the...
In our last work we developed a reluctance type pressure transducer which was simple and low cost. Its theoretical analysis was presented. But its linearity was good for low pressure range, for high pressure range its linearity was hampered. But improvement in signal conditioning circuit can give some satisfactory result in high pressure range also. In this paper we have designed a microcontroller...
This paper mainly brings out the details related to a prototype biodiversity information retrieval system that has been setup using the distributed Grid-Cloud resources of GARUDA Grid project, India. The overall experiment has been done with the help of open source biodiversity databases. The structure of these relational database tables are not standardized and are hosted on a variety of Database...
Computational grid and high performance computing resources are widely used by researchers and academicians for research activities. Stable and reliable computational resource is essential. In order to achieve this apart from monitoring network health, service health etc knowing job statistics also equally important, hence Job Accounting Tool(JAT) is designed for this functionality. JAT is a web based...
In this paper we have presented a moment method analysis of a shunt - series slot fed waveguide broad wall shunt slot radiator. To analyze the circuit Multiple Cavity Modelling Technique (MCMT) has been used. The theory has been validated by the excellent agreement obtained between the MCMT and Ansoft HFSS simulated data.
The accurate measurement of Pressure at the desired value is needed in order to obtain good quality of product at maximum efficiency of a process plant or equipment and also to run the plant with all the safety aspect. In the present paper, a low cost reluctive pickup type transmitter has been described where the displacement of the ferromagnetic core attached with the tip of the bourdon tube is found...
Grid computing is a collaborative e-infrastructure to solve large multidisciplinary problems having interrelated demands of data, compute, scientific instruments and increased importance of collaboration. Grid is a distributed system which enables sharing, selection, and aggregation of heterogeneous geographically distributed autonomous resources dynamically depending on their availability, capability,...
The small inductance of an inductive transducer generally linearly changes with a process variable, but their measurement by the usual inductive bridge circuit like the Maxwell bridge, the Maxwell-Wien Bridge, the Hay bridge, etc., suffers from errors due to the effect of the stray capacitance between bridge nodal points and the ground and the stray inductance on the inductive coil, respectively....
