Planning of the optimal path has always been the target pursued by many researchers since last five decade. Its application on mobile robot is one of the most important research topics among the scientist and researcher. This paper aims to plan the obstacle-avoiding path for mobile robots based on the Artificial Immune Algorithm (AIA) developed from the immune principle. An immunity algorithm adapting capabilities of the immune system is proposed and enable robot to reach the target object safely and successfully fulfill its task through optimal path and with minimal rotation angle efficiency. Finally, we have compared with the GA based path planning with the AIA based path planning. Simulation results show that the mobile robot is capable of avoiding obstacles, escaping traps, and reaching the goal efficiently and effectively by using AIA than GA. © 2012 Springer-Verlag Berlin Heidelberg.

Noise Control Engineering Journal | Year: 2010

Artificial neural network models are simple to apply and have generated a great deal of interest in engineering. By considering the successfully application of artificial neural networks in complex engineering problems, in this paper, artificial neural network system based noise prediction models were developed for predicting far field noise levels due to operation of specific set of mining machinery. Multi-Layer Perceptron (MLP) and Radial Basis Function Network (RBFN) systems were used to predict the machinery noise in opencast mines. The proposed models were designed with VDI-2714 noise prediction model. It was taken due to simplicity, for design of artificial neural network system based noise prediction models for opencast mines. From the present investigations, it was observed that the RBFN model gave better noise predictions than the MLP model. © 2010 Institute of Noise Control Engineering.

Noise is often regarded as a nuisance rather than as an occupational hazard in an opencast mining environment. Prolonged exposure to noise over a period of years generally causes permanent damage to the auditory nerve and/or its sensory components. To maintain the good working environment in mines, appropriate noise survey of machineries should be conducted. The measured sound pressure levels (SPL) of equipment are not accurate due to instrumental error, attenuation due to geometrical aberration, atmospheric attenuation etc. Some of the popular noise prediction models e.g. CONCAWE, VDI and ENM have been applied in mining and allied industries to predict the machineries noise by considering all the attenuation factors. In this paper, authors have predicted machineries noise in an opencast mine using CONCAWE model.

Service Oriented Architecture (SOA) based application can be composed of heterogeneous self-contained independent services on the web. These applications are usually modified to fix bugs or to enhance their functionality. These modifications are quick and they should be supported by rapid verification. Regression Test (RT) is essential to ensure that modifications do not result in adverse effects. Regression Test Selection (RTS), one of the cheapest techniques, aims at decreasing cost of carrying out RT. This paper presents a Control Flow Graph (CFG) based approach that makes it feasible to apply a safe RTS technique to SOA based applications or services in an end-to-end manner. Safe RTS technique guarantees that no modification revealing tests will be left unselected. A simplified navigational subsystem that involves 3 services, is used to elicit our approach. © 2014 SERSC.

Web services represent the class of Service Oriented Architecture (SOA) based applications with a hugely diversified domain. Web service regression testing presents a set of challenges to the tester which need to be overcome in order to provide a reliable performance of the desired application. Code based regression testing approaches present a lot of difficulties as the tester needs to know the code which is in most cases not possible. In this paper, we address a UML based regression testing method independent of the code using test cases generated from use cases in the context of a case study. © 2006-2012 Asian Research Publishing Network (ARPN).

Nonlinear dynamic systems are characterized with uncertainties in terms of structure and parameters. These uncertainties cannot be described by deterministic models. The modelling and identification of nonlinear dynamic systems through the measured experimental data is a problem in engineering and technical processes. Therefore, field of system identification have become an important area of research. Fuzzy technology is an effective tool for dealing with complex nonlinear processes that are characterized with uncertain factors. In this paper, a novel approach based on Local Linear method learning in dynamical filter weights neurons for the identification of non-linear dynamic systems is presented. The fuzzy wavelet neural network combines wavelet theory with fuzzy logic and neural networks. Learning fuzzy rules and parameter update in fuzzy wavelet neural network is based on gradient decent method. The proposed approach is said to be Fuzzy Local Linear Wavelet Neural Network based model. It has been explained through examples. The structure is tested for the identification with both wavelet neural network and Fuzzy Local Linear Wavelet Neural Network that shows the comparative performance. © 2013 Springer International Publishing.

Biodegradable films of Soy Protein Concentrate (SPC) and Cloisite 30B (C 30B) have been prepared by melt extrusion method in which C 30B was used as a nanofiller. The structures and properties of the films were characterised by FTIR, XRD, SEM, TEM, TGA and tensile testing. Soy Protein Concentrate/Cloisite 30B hybrids showed an intercalated nanostructure due to the compatibility of the two components. The biodegradability of the films was investigated by three different methods like soil burial, compost burial and enzymatic degradation. In all the three methods the films containing C 30B clay were found to be more biodegradable than those SPC films without C30B.
