This article contains information about computer network and system remote management technologies such as SNMP, DMI and WBM, including an architectural overview and mutual comparison. There is also a look in a practical usage of these technologies as well as in management problems. In the main, it describes the author's provided management mechanism based on SNMP modifications. Finally, several pieces of advice are given about what has to be taken into account when implementing computer network and system remote management systems.

Phonocardiography is defined as graphics representation of heart sounds, which rise from heart and surrounding vessels. These sounds are scanned from skin surface. Phonocardiography provides significant help with diagnosing of inborn and non-inborn heart diseases and pathological changes in vessels. This method is particularly valuable for surgeons when deciding whether or not to perform a surgery. During the phonocardiography scan is simultaneously performed an electrocardiogram scan for analyzing heart sounds. Sampled signal are transferred to the computer via sound card input. Signals sampled by software are saved into the database and they are analyzed from the database later. Software allows simultaneously sampling and real-time analyzing signals

A nonlinear optimization-based identification procedure for fully parameterized multivariable state-space models is presented. The method can be used to identify linear time-invariant, linear parameter-varying, composite local linear, bilinear. Hammerstein and Wiener systems. The nonuniqueness of the full parameterization is dealt with by a projected gradient search to solve the nonlinear optimization problem. Both white and nonwhite measurement noise at the output can be dealt with in a maximum likelihood setting. It is proposed to use subspace identification methods to initialize the nonlinear optimization problem. A computationally efficient and numerically reliable implementation of the procedure is discussed in detail.

This paper is concerned with an application study of model-based fault detection method to a ship propulsion system. When modeling the object system, Quasi-ARMAX model with multi-model form is used. In this model, the system non-linearity is incorporated into model parameters by using non-linear non-parametric models (NNMs). Kullback discrimination Information (KDI) is introduced as fault detection index to evaluate the distortion in identified model, which is caused by a fault. The effectiveness of the method is verified through simulation studies on the ship propulsion system.

In this paper a description of a communication system based on 8-bit microcontroller is given. We think, that it is important to demonstrate the students a very commonly used devices such as LCD displays, matrix keyboard and most industrially used communication interfaces in a clear and simple way. Students also get a basic knowledge of Global Positioning System (GPS), used for position's location.

A control systems engineering approach, employing a two-level overall system architecture and different but compatible formalisms for system representation on the upper and lower levels, has been investigated in detail. One design alternative is based on employing fuzzy-system approximators and solving for the adaptive tracking of the given, arbitrary, desired system outputs. The other alternative is based on state equations of composite systems and the use of neural-network approximators to deal with uncertainties and control adaptation. In both alternatives similarity property of subsystems has been exploited. Both designs can be implemented within the standard computer process control technology, and are therefore believed to be promising in applied systems engineering.
