Originally this word “cybernetics” came from the Ancient Greece, and it meant “the art of steersman”. Cybernetics is the “old-fashion” term for what is now called as the general system’s theory, or the system science. We can admit that cybernetics was born in 1948, when the book with the same title has been written by the famous American mathematician Norbert Wiener (1894-1964) [1]. The diction...

The purpose of this paper is to present a brief sketch of the evolution of modern control theory. Systems theory witnessed different stages and approaches, which will be very shortly presented. The main idea is that, at present, Control Theory is an interdisciplinary area of research where many mathematical concepts and methods work together to produce an impressive body of important applied ma...

TIERE is perhaps no literature dealing with specific disease addressed to the patient so voluminous as that on the subject of diabetes. This can probably be explained by the fact that there is no other disease in which the physician has to rely, to the same extent, upon self-treatment by the patient. Yet in spite of the plethora of books, this small volume, written by a certified dietitian, wil...

Modern operating systems each have different implementations of access controls and use different policies for determining the access that subjects may have on objects. This paper reviews the three main types of access control policies: discretionary, mandatory, and role-based. It then describes how Windows and various Unix systems implement their chosen access control policies. Finally, it dis...

In this paper, the method of modern control approach for the design of controller and observer is used. Other functions such as neural controllers - or fuzzy sliding mode control can be found in this work and the results are compared. First, a dynamic model of the servo valve is intended for the governing equations in state-space form expression are obtained. Due to the system integrator is exp...

The greenhouse are classified as complex systems such as large lag, multi-input multi-output (MIMO), non-linear and difficult to create mathematic model and so on, so it is difficult to implement classical control methods for this kind of process. A new sectional-control strategy is put forward. It uses different control modes for different deviation domains. The new strategy is based on MPT in...

A portfolio management is concerned with objectives related to the outperformance of the return of a target benchmark portfolio. In this paper, we consider a dynamic active portfolio management problem where the objective is related to the tradeoff between the achievement of performance goals and the risk of a shortfall. Specifically, we consider an objective that relates the probability of ach...
