A new view on uncertain system parameters is presented considering them in the same way as other independent variables, e.g., time or space variables. After re-interpreting the well known equations for the sensitivities of a system to parameter changes, we consider the problem of optimal control ...

Functional architecture enables the description of systems independent of their technology. A method for obtaining functional architectures for systems (the FAS method) is introduced. It provides a well-defined procedure for deriving functional architecture from use cases by using heuristics for ...

Cognitive Radio has been one of the key research topics in the wireless community for about 10 years. The digital switch-over in the TV bands provides opportunities for Cognitive Radio Systems (CRS) to operate in the 470–790 MHz spectrum under incumbent protection restrictions. Locally unused...

The mixture of conflicting transitions and concurrent transitions in Petri nets can lead to the loss of conflict information, which is an unfortunate phenomenon in discrete event systems, usually called confusions. They appear in the processes of resource allocation and may cause incomplete decis...

This paper deals with the integration process in technological systems projects. The paper reviews the objectives of the integration process, planning and managing principles, as well as the pitfalls and difficulties associated with this process. The following integration approaches are described...

This paper introduces a procedure to assess the credibility of models and simulations (M&S) as a group activity based on NASA’s new standard for M&S NASA-STD-7009. The Delphi method, which is characterized by iterative surveys with controlled feedback, was selected to implement the assessment. ...

With commercial and military systems becoming more complex, using more sophisticated products, complex processes, and specialized people and having longer system life cycles, it is essential that organizations have a systematic approach to managing systems from an Obsolescence Management System p...

In this paper, three fundamental properties of a potential field-based flocking algorithm, i.e. merging of neighbouring graphs during the system evolution, collision avoidance and convergence of position of the centre of mass of informed agents to that of virtual leader are discussed. Next, these...

In this paper, a hyperchaotic system is presented as the chaotic carrier to encrypt information in secure communication. The sensitivity to the system parameters and delay of the hyperchaotic system, i.e., its chaotic degree indicated by the number of positive Lyapunov exponents, increases with i...

Multirate sampled system can be seen in many industries and several kinds of control method using lifting method have been proposed. Unfortunately, it was difficult to deal with nonuniformly sampled multirate systems. In this paper, we will propose a design scheme of output feedback control with ...

This paper is concerned with regional stability analysis and regional stabilization of time-delay systems subject to both actuator saturation and delay. By using a novel Lyapunov-Krasovskii functional, the corresponding conditions for regional stability and stabilization are derived. The free par...

The guidance law design for the missile–target interception problem in the presence of system uncertainty is investigated in this paper. To improve the disturbance rejection property, two kinds of non-smooth guidance laws based on a finite-time control technique are developed. The first is ...

Rework that occurs late in the product life cycle is dramatically more expensive than design work performed early in the cycle. However, shifting traditional design work earlier in the design process so as to avoid rework later is difficult. A number of product development practices that have bee...

To design highly efficient and robust detectors of a weak signal, an asymptotic approach to stable estimation exploiting redescending score functions is used. Two new indicators of robustness of detection, the detection error sensitivity and detection stability, are introduced. The optimal Neyman...
