We consider the theoretical and practical aspects of locating acoustic sources using an array of microphones. A maximumlikelihood (ML) direct localization is obtained when the sound source is near the array, while in the far-field case, we demonstrate the localization via the cross bearing from several widely separated arrays. In the case of multiple sources, an alternating projection procedure...

In our country, Student transportations’ security and driving accidents statistics for students is one of the major concerns for relevant organizations such as educational organization. In current year, a system, was named Sepand, was formed in city taxi driver ::::::union:::::: by educational organization, NAJA traffic and city taxi driver ::::::union::::::. In this systems’ plan, ...

implement a locating system that provides accurate results. However, a locating system utilizing asynchronous ranging generates a large number of messages that cause transmission delays or failures and degrades the system performance. This paper proposes a novel approach for efficient congestion control in an asynchronous rangebased locating system. The proposed method significantly reduces the...

This article presents the problem of locating electric vehicle (EV) charging stations in a city by defining Electric Vehicle Charging Stations Locations (EV-CSL) problem. The idea is to minimize distance citizens have travel charge their vehicles. EV-CSL takes into account maximum number install and power requirements. Two metaheuristics are applied address relying optimization problem: genetic...

this paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

In this note we deal with a practical problem arising at ENCI Netherlands BV. ENCI is a major producer of cement. Its factory site is located south of Maastricht where an important ingredient of cement, marl, is digged from a quarry. The following situation occurs at the site of ENCI. There are different kinds of traac on the site and the vehicles of each kind of traac follow a xed route on the...

in this paper, an adaptive rule based controller for an anti-lock regenerative braking system (arbs) of a series hybrid electric bus (sheb) has been proposed. the proposed controller integrates the regenerative braking and wheel anti-lock functions by controlling the electric motor of the hybrid vehicle, without using any conventional mechanical anti-lock braking system. the performance of the ...

Research on the problems of creating effective control and diagnostic systems allows us to single out following areas: development theory methods for diagnosing predicting strength reliability structures, theoretical experimental studies fracture processes corresponding changes in characteristics parameters, i.e. carriers information about occurring material during destruction; creation informa...
