This paper deals with the Speech/Music classification problem, starting from a set of features extracted directly from audio data. Automatic audio classification is very useful in audio indexing; content based audio retrieval and online audio distribution. The accuracy of the classification relies on the strength of the features and classification scheme. In this work Perceptual Linear Prediction (PLP) features are extracted from the input signal. After feature extraction, classification is carried out, using Support Vector Model (SVM) model. The proposed feature extraction and classification models results in better accuracy in speech/music classification.</p> 2019-02-14T16:59:59+00:00 ##submission.copyrightStatement## http://ijecs.in/index.php/ijecs/article/view/4283 On Image Processing Algorithm for Registration of Three-Dimensional Gas Bubble Movement Using a High Speed Camera 2019-03-26T15:52:21+00:00 Jakub Augustyniak j.augustyniak@pb.edu.pl Dariusz Mariusz Perkowski d.perkowski@pb.edu.pl <p>The paper deals with an imaging computer tomography method based on simple image processing techniques for two phase flow analysis. Moreover, it has been presented the algorithm of 3D bubble trajectory reconstruction using a single high speed camera and the system of mirrors. In the experiment a glass tank filled with distilled water was used. The nozzle through which the bubbles were generated was placed in the center of the tank bottom. Through the use of basic image processing and analysis techniques such as noise reduction, smoothing, edge detection and few algorithms like close contour filling, tracking single bubble etc. proposed in paper it became possible to draw out 3D trajectories for gas bubble paths in liquid. In the paper the measurement error of imaging computer tomography method has been estimated. The maximum measurement error recorded for this method was within the limits ±0,65 [mm] for a certain set of parameters like: resolution, mirror angle and deviation error of z axis from the 90<sup>o</sup> vertical line. Trajectories of subsequently departing bubbles were visualized in the form of figures.</p> 2019-02-22T07:17:21+00:00 ##submission.copyrightStatement## http://ijecs.in/index.php/ijecs/article/view/4229 Survey of mobile ad hoc networks (manets) 2019-03-26T15:52:20+00:00 Abdulghani Saif Kasem Mohammed alhaidari72@gmail.com khalid Hamid Bilal editor@ijecs.in <p>Mobile Ad Hoc Network (MANET) is the one of the type of ad hoc network, the MANET is a collection of two or more devices or nodes or terminals with wireless communications and networking capability that communicate with each other without the aid of any centralized&nbsp; administrator also the wireless nodes that can dynamically form a network to exchange information without using any existing fixed network infrastructure. And it's an autonomous system in which mobile hosts connected by wireless links are free to be dynamically and sometime act as routers at the same time, In MANET, the mobile nodes require to forward packets for each other to enable communication among nodes outside of transmission &nbsp;range. The nodes in the network are free to move independently in any direction, leave and join the network arbitrarily. Thus a node experiences changes in its link states regularly with other devices. Eventually, the mobility in the ad hoc network, change of link states and other properties of&nbsp; wireless transmission such as attenuation, multipath propagation, interference etc. This paper discuses &nbsp;&nbsp;study of Mobile ad-hoc Networks (MANET): classification, characteristics, structure of&nbsp; MANET &nbsp;and challenges that are imposed by Mobile ad-hoc Networks.</p> 2019-02-22T07:30:10+00:00 ##submission.copyrightStatement##
