This paper investigates the fault estimation problem for discrete-time switched systems. Firstly, sensor is regarded as an augmented state, and then original system converted into a singular system. After that, based on obtained system, robust state observer designed using $ L_{\infty} technique. Given above observer, interval zonotope method established to complete estimation. Finally, circuit...

This paper addresses the problem of estimating the rendering time for a real-time simulation. We study different factors that contribute to the rendering time in order to develop a framework for rendering time estimation. Given a viewpoint (or view cell) and a list of potentially visible objects, we propose several algorithms that can give reasonable upper limits for the rendering time on consu...

In the present paper, nonlinear behavior of mass concrete simulated by smeared crack model is combined with Endurance Time Analysis (ETA) method for studying seismic response of arch dams. ETA is a time-history based dynamic pushover procedure in which special predesigned intensifying acceleration functions are used for analysis and estimation of structural responses in various performance leve...

Time-delay estimation (TDE) is a common requirement of the ranging and localization systems often found in unattended ground sensors. In this paper we consider novel approaches to the TDE problem in a time-warping acoustic environment, such as that encountered when the propagation velocity is not constant—due to wind gusts, for example. An increasing propagation velocity induces a compression o...

    Dynamic model,   regional economy,   innovation.   This paper presents a normative balance mathematical model of regional economy that contains a lot of unspecified parameters which are not defined directly by the data of economic statistics. A method for estimation of the model parameters by application of parallel computations on multi-processors systems is presented. It is determined the...

The development of communications and telecommunications infrastructure, followed by the extension of a new generation of smart distribution grids, has brought real-time control of distribution systems to electrical industry professionals’ attention. Also, the increasing use of distributed generation (DG) resources and the need for participation in the system voltage control, which is possible ...

due to increasing growth of air traffic, it is very important to have a reliable air traffic control system. usually secondary surveillance radar systems are employed for this task. in this paper, a new approach is presented to identify interrogators location of this system. the proposed method works passively and uses just a single receiver. this goal has been reached using angle and time diff...
