Using the underlying idea of the current-mode control, a new dynamical, sliding-mode control for the boost dc-dc converter is proposed. Such controller is easy to design, robust under load and input voltage variations, exhibits fast response, does not depend on…

In this paper, we present a novel model of an artificial immune system (AIS), based on the process that suffers the T-Cell. The proposed model is used for solving constrained (numerical) optimization problems. The model operates on three populations: Virgins,…

of the remaining 263 species, we arrived at a specieslevel identification for 242, and identified the remainder to genus (19) or family (2). The recent discovery of these ornithological texts and paintings offers a unique view of the history of…

This paper describes the implantation of a KA tool kit for use with sublanguage-specific corpora. The key idea of KA as an evolutionary process is discussed in detail. Special attention is paid to the system's attempt to avoid the pitfalls…

ABSTRACT









Population size has been a matter of concern for rulers and states for centuries. Fears of over- and under-population led to extensive political debate and the implementation of numerous policies…

In this paper, a method to combine visual and force information using the
information obtained from the movement flow-based visual servoing system is proposed. This
method allows not only to achieve a given desired position but also to specify the…
