X-ray like volume rendering is adapted to time-varying data visualization. The proposed method can be interpreted as an object-order version of differential volume rendering. Time steps are encoded as a sequence of differential volumes which are then directly projected onto the image plane to calculate differential images between consecutive frames. The projection of differential volumes is performed by using the splatting method. Due to the simplified visualization model and the object-order approach, those pixels which are affected by the changed voxels can be directly refreshed, without resampling the volume by ray casting. However, compositing is limited to intensity integration. In order to improve spatial impression, differential splatting is extended to depth cueing and hemispherical shading.

This contribution is dealing with the problems of distributed systems for the building control. The universal system for building automation being developed in department of Measurement and control, VSB-TU Ostrava is described here. The system makes use of the communication network Lonworks and serves for control and mutual interconnection of the building technical equipment. In the frrst part of the contribution the technologies used in the building control sphere are decribed. In the second part the system being developed and laboratory model, on which the system is applied, are described.

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

The development of electronic commerce systems is subject to different conditions than that of conventional software systems. This includes the introduction of new activities to the development process and the removal of others. An adapted process must cope with important idiosyncrasies of EC system development: EC systems typically have a high degree of interaction, which makes factors like ergonomics, didactics and psychology especially important in the development of user interfaces. Typically, they also have a high degree of integration with existing software systems such as legacy or groupware systems. Integration techniques have to be selected systematically in order not to endanger the whole software development process. This article describes the development of an EC system and it generalizes salient features of the software process used. The result is a process model that can be used for other highly integrative EC system development projects. The processes described are determined by short process lifecycles, by an orientation towards integration of legacy systems and by a strict role-based cooperation approach

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.

Analysis of heart rate variability serve as associated production diagnostic method in cardiology. Most often go plotting from long-term 24 hourly or short-term 5- minute record's of electrocardiogram. Payoffs this work is processing of short-term record's and evaluation qualitative changes heart rate. With the view ofplotting record's has been also designed and realized application program in MATLAB environment, which makes it possible well-arranged orientation in designed method detection and analyses single ECG recording. For evaluation designed progress and method was using sense course extract from medical database clinical electrocardiography record Physionet. Calculation immediate value heart rate does by the help of two-implement detector R wave's. These way get results are use for depiction waveform heart tachogram, which sequentially transforms into frequency areas with the view ofanalyses spectral coulisses. Final exit processing is classification physiological or morbid changes heart rate mensuration patient's. The results of those work may be contribution for recognition causes complex sudden death near newboms and small children
