Optimal damping concept: features and applications

A New Optimal Solution Concept for Fuzzy Optimal Control Problems

In this paper, we propose the new concept of optimal solution for fuzzy variational problems based on the possibility and necessity measures. Inspired by the well–known embedding theorem, we can transform the fuzzy variational problem into a bi–objective variational problem. Then the optimal solutions of fuzzy variational problem can be obtained by solving its corresponding biobjective variatio...

Optimal Damping of Forced Oscillations

In this paper we consider a linear discrete-time control system affected by an additive sinusoidal disturbance with known frequencies but unknown amplitudes and phases. The problem is to damp this forced oscillation in an optimal fashion. We show that the natural solution from the point of view of optimal control is neither robust with respect to errors in the frequencies, and thus not optimal ...

Context-aware systems: concept, functions and applications in digital libraries

Background and Aim Among the places that context-aware systems and services would be very useful, are libraries. The purpose of this study is to achieve a coherent definition of context aware systems and applications, especially in digital libraries. Method: This was a review article that was conducted by using Library method by searching articles and e-books on websites and databases. Results:...

The Exponentiated Poisson-Lindley Distribution; Features and Applications in Reliability

Abstract. In this paper a new three-parameter lifetime distribution named “the Exponentialed Lindley-Poisson (E-LP) distribution” has been suggested that it has an  increasing, decreasing and invers bathtube hazard rate depending on the parameter values. The (E-LP) distribution has applications in economics, actuarial modeling, reliability modeling, lifetime and queuing problems and biological ...
