this paper focuses on the non-fragile guaranteed cost control problem for a class of t-s fuzzy time-varying delay systems with local bilinear models. the objective is to design a non-fragile guaranteed cost state feedback controller via the parallel distributed compensation (pdc) approach such that the closed-loop system is delay-dependent asymptotically stable and the closed-loop performance i...

We study a mathematical model describing the dynamics of a pluripotent stem cell population involved in the blood production process in the bone marrow. This model is a differential equation with a time delay. The delay describes the cell cycle duration and is uniformly distributed on an interval. We obtain stability conditions independent of the delay. We also show that the distributed delay c...

in this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. the concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (ir-tf), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. ir-tfs, which are well c...

The DTN architecture is based around sender-initiated unicast communication that is insufficient or inconvenient to meet the needs of many applications. To address these limitations, we define a DTN session layer and associated extensio...

Decentralized algorithms are examined for optimally distributing a divisible resource in a distributed computer system. In order to study this problem in a specific context, we consider the problem of optimal file allocation. In this case, the optimization criteria include both the communication cost and average processing delay associated with a file access. Our algorithms have their origins i...

This paper identifies properties of bounded and unbounded delay-robustness for distributed supervisory control for timed discrete-event systems (TDES) with communication delay. In our previous work, for untimed DES we have proposed an effective verification tool to identify delay-robustness for distributed controllers constructed by the supervisor localization procedure. Delay-robustness means ...
