Flexibility and safety are often considered conflicting concepts because flexibility implies dealing with changing requirements that can, in turn, produce unpredictable and possibly unsafe operating scenarios. Therefore, some in the automotive and avionic system design industry believe that a safety-critical system implies a fully static system in which all operating conditions are completely d...

Discrete-time designs of flight control systems are required for implementation on missile-borne computers. While extensive literature is available on linear discrete-time control system design methods, nonlinear discrete-time control system design techniques have not been discussed to the same degree. This paper presents three nonlinear, discretetime control system design methods. These are th...

this paper presents a simplified approach to estimate the resultant force, which should be provided by a retention system, for the equilibrium of unstable slopes. the results were obtained with a developed algorithm, based on limit equilibrium analyses, that assumes a two-part wedge failure mechanism. design charts to obtain equivalent earth pressure coefficients are presented. based on the res...

The paper deal about automated assembly manufacturing cell design. First part is about Methods and techniques used for assembly systems design. Next part describes specific CAD systems used for design process of our assembly cell. With help of this CAD toll we have design geometric disposition of all system elements by CATIA and also parts of control system by FluidSim. Whole design problematic...

The purpose of this paper is three fold. First, the major theoretical pattern relationships of TV and/or FM transmitting antennas are dealt with. Secend, the computer calculation method and designing of such patterns using the given relationships. And third, a method in which a computer graphic system can be used to design such antennas for a specific pattern is introduced and its results are p...
