Paper Title:

Optimization of Operating Parameters for EDM Process based on the Taguchi Method

Abstract:   In this paper the complexity of electrical discharge machining process which is very difficult to determine optimal cutting parameters for improving cutting performance has been reported. Optimization of operating parameters is an important step in machining, particularly for operating unconventional machining procedure like EDM. A suitable selection of machining parameters for the electrical discharge machining process relies heavily on the operators’ technologies and experience because of their numerous and diverse range. Machining parameters tables provided by the machine tool builder cannot meet the operators’ requirements, since for an arbitrary desired machining time for a particular job, they do not provide the optimal machining conditions. An approach to determine parameters setting is proposed. Based on the Taguchi parameter design method and the analysis of variance, the significant factors affecting the machining performance such as crater diameter,recsat layer,grain size,haz for a hole machined by EDM process, are determined.

Keywords:    complexity, Optimization, EDM, significant factors.

Paper Title:

Detection of Air gap Eccentricity Fault of Three Phase Induction Motor by Fast Fourier Transform Using ARM Microcontroller

Abstract:    Induction machines are the backbones of many industrial processes due to its robustness and reliability. Online fault diagnostics of induction motor is important, and its real function is to attempt to recognize the development of faults at an early stage, which are highly useful preventive rescue especially in high power applications. Among various faults occurred in induction motors, eccentricity faults are of significant importance as they produce secondary effects that can lead to a major fault to a motor. Using different signal processing and mathematics techniques, the stator current signals of a motor can be analyzed, interpreted and faults inside the motor can be identified. It is observed that the fault frequencies for different faults of induction motor are unique. This paper investigates on detection of air gap eccentricity fault in three phase cage induction using modulated motor stator current.. MCSA (Motor Current Signature Analysis) technique using FFT (Fast Fourier Transform) approach is utilized in this research work to identify air gap eccentricity fault of induction motor under different loading conditions. Hence, in this paper RISC (Reduced Instruction Set Computing) based ARM (Advanced RISC Machine) architecture controller (LPC2148 from NXP) for current signature analysis is developed to analyze the air gap eccentricity fault. An experimental setup, using the ARM based data acquisition board and PC based analysis software is also developed and results are given for air gap eccentricity fault.

Paper Title:

Image Resizing with Enhancement Technique on DCT Domain

Abstract:       This paper presents an image resizing technique with enhancement process so as to get an enhanced resized image. This technique is applied on single DCT domain and it is based on the energy compaction and de-correlation property of DCT. Resizing is based on energy compaction while enhancement is based on de-correlation property of CDT. In this technique, resizing is implemented on arbitrary ratio of dimension of the resized image. Enhancement technique is applied by rescaling the AC and DC values of the DCT matrix of the input image.  Since it is applied on single DCT domain there is no blocking artefact like block domain. The performance of this technique is compared with other related techniques using PSNR, RMSE and CCC and found outperform.

Keywords: Image Resizing, Arbitrary Ratio,  DCT, Enhancement, Power-Law.

Recognition of Medicinal Leaves using PCA & SVM

Abstract:   In pharmacological science and bhaishaja kalpana, the recognition of plant leaves(leaf) is very important to make medicine. A Recognizing plant leaf has so far been an important and difficult task. In this paper leaf recognition system using the support vector machine as a classifier is proposed. The leaf recognition system consists of image acquisition, preprocessing, feature extraction and classification. The preprocessing involves  a typical image processing conversion  such as transforming color images to gray scale image then binary , smoothing and to contour image etc. In the feature extraction involves  geometrical features are extracted from leaf images such as diameter, length, area, and perimeter etc. Total 10 digital morphological features (DMF) including geometrical features. These 10 features are  orthogonalized into five principal variables using principal component analysis (PCA). These features are given as input vector to the support vector machine (SVM) for classifying leaves.

Analytical Investigation of Cable Stayed Bridge Using Various Parameters

Abstract:   In this paper, analysis of 240 m long fan type cable stayed bridge having single plane of cables is carried out with the help of software facilities. Effects of various parameters such as stiffness of deck and pylon and number of cables on the behaviour of cable stayed bridge were observed. To save time in modelling of bridges manually, a programming tool has been developed in excel software with the help of visual basic macro for the purpose of parametric study of Cable stayed bridge. With the help of this tool, number of models of cable-stayed bridge can be automatically generated in software SAP-2000. From the analysis of number of models, comparison of bending moments at critical locations in the structure is done.
