The mathematical model (Interval Plant) of the web guide in cold rolling mill(CRM) is controlled using PID controller [1]. The given interval plant of the CRM is approximated to FOPTD +Integrator system using Sundaresan& Krishnamoorthy method.[2] The controllers are tuned using direct synthesis method proposed by Seshagirirao et. al. Rao [5], Ziegler – Nichols technique(Z-N), internal model control(IMC) and the performances are compared by simulation. Using direct synthesis method, a PID controller in series with lead/lag compensator is designed for control of integrating plus first-order time delay( IFOPTD) process. Guidelines are provided for selection of the desired closed loop tuning parameter. The method gives significant load rejection performances. The direct synthesis method gives simple equations for the controller settings. The performance of the closed loop system is evaluated for both original and approximated modelThe abstract is to be in fully-justified italicized text as it is here, below the author information.

In this paper a novel approach to detect various faults occurring in the induction motor is presented. Both vibration and motor current signature analysis are performed to detect the mechanical and electrical faults. Multi-scale decomposition process using wavelet packet transform is performed on the obtained signal to extract the features. The extracted features are given to a classifier to identify whether a fault has occurred. If a fault exists, it identifies the fault location and isolates it. The various faults discussed in this paper are: mechanical faults— such as bearing faults and electrical faults occurring in the rotor and stator parts of an induction motor. Multiple Support Vector Machine using the one-against-others approach is used to obtain multi-class classification of fault.

This paper deals with the problem of tracking control for Takagi-Sugeno fuzzy model. An LMI (Linear Matrix Inequality) formulation is suggested to make possible the convergence of the state vector of the continuous-time system to a desired one using a new approach, called MultiQuadratic Fuzzy Lyapunov (MQFL). A fourth order unstable nonlinear system is studied to illustrate the efficiency of this formulation and to compare the corresponding simulation results with the obtained stability conditions based on the quadratic Lyapunov function.

Analyzing and evaluating various noise avoidance techniques such as driver sizing, wire sizing, wire spacing and layer assignment. This paper presents an approach to solve the VLSI (very large scale integration) layer assignment problems that will leads to minimization of crosstalk noise. Our approach is based on Genetic Algorithm (GA) with introduction of modified GA operator, which is used to solve our problem that is formulated in a graphcoloring problem. In this paper, we study the problem of crosstalk minimization in 3-layer HVH channel routing without considering dogleg.

This Paper presents an analysis of single ended low Noise Amplifier in a transceiver for wireless sensor network. The Low Noise Amplifier consumes a Power of 65.9μ W. The Noise analysis for the LNA is achieved for a frequency range of 1GHZ-3GHz.

In this project, we have studied the growth, morphology and surface characterization of metallized Carbon Nanotubes and conducted a comprehensive study on the application of this technology. Carbon Nanotubes are a tubular shaped isotope of carbon with unique physical, chemical and mechanical properties. In particular, we synthesized Carbon Nanotubes, using a RF-Powered Plasma Enhanced Chemical Vapor Deposition System. In this process, we used methane as the carbon source and high purity argon gas to create the plasma. The Silicon (Si)/Glass (SiO2) substrate was coated with a transition metal as a catalyst using both wet chemical means and Electron beam Evaporation. After successfully growing Carbon Nanotubes, they were metallized with Iron (Fe) Nanoparticles using Physical Vapor Deposition System with an E Beam Evaporator. A comparative study between the metal coated and non coated Carbon Nanotubes was conducted. Possible applications such as use of this technology in synthesis of FET’s, use as Scanning Probe Microscope tips and other electronic applications are also discussed. A successful development in this field would have enormous applications in various fields and could lead to fabrication of miniature electronic components (in the order of nanometers).
