    An electrocardiogram is quite an important tool to find out more information about the heart. Despite the presence of serious noise, reliable detection of the QRS complex, and T and P waves is essential for an exact ECG analysis system. ECG analysis methods can be divided into three functional groups: direct methods, transformation methods, and parameter estimation methods. For real-time processin... View full abstract»

    Artificial neural networks (ANN) were previously proposed by the author as a technique for solving the inverse problem of electrocardiography. The aim of the paper is to find the training limits of the input data for this problem and the related probability of output errors. Using a model of a homogeneous spherical body, the cardiac source was represented by six current dipoles located on the surf... View full abstract»

    The forces acting between teeth during the mastication of food have not been determined exactly until now. The exact value of forces between mandibles is very important for the determination of forces in musculus temporalis, m. masserter and m. pterygoideus with regard to the predetermination of the deformations of the mandibles and the shifts (the stability and non-stability) of each tooth. The a... View full abstract»

    In 1996, a new phenomenon in computer programming emerged-the Java language and its system support. The language was originally designed by Sun developers for small embedded applications. The idea behind it was to create an object-oriented language, simpler than C++, that would be more reliable and provide higher portability. Although its current success is bound to the specific application (viz. ... View full abstract»

    Multimedia technology is gaining wide acceptance in desktop computing and commercial and consumer applications due to its high performance, lower cost, and higher level of integration. Multimedia allows computer-based systems to deliver information to the user in ways other than the traditional methods of text. The new forms of information delivery include high-resolution images, realistic 2D and ... View full abstract»

    A system for the modeling of some human organs and biochemical processes was implemented at the Department of Control Engineering, Faculty of Electrical Eng., CTU in Prague. The main task was to apply computer technology in biomedicine and to improve resources in biomedical investigation. A simulation running under Windows with the support of Matlab was used as a software package. The authors have... View full abstract»

    Virtual reality (VR) is only a decade old, but medicine is beginning to see the potential for this technology to revolutionize the practice of medicine. On the other hand, robotics and automation have been used in science and industry for over three decades, yet there are precious few applications within the medical field. However, the introduction of laparoscopic surgery, which requires operating... View full abstract»

    Atherosclerosis is a complex, multi-factorial process. It develops over many years without clinical manifestations. Many factors positively or negatively affect its development. The primary prevention strategy involves modification of the so-called risk factors (RF) in those individuals without clinical signs of the disease and covers two approaches. The aim of the population approach is to influe... View full abstract»

    Summary form only given. Heart rate variability (HRV) is an important marker in the diagnostics of some diseases associated with autonomic nervous system (ANS) dysfunctions. One of the advanced methods is the spectral analysis of heart rate variations (SAHRV). Early diagnosis of ANS disfunction is very important from the point of view of prevention and subsequent therapy. This fact served for the ... View full abstract»
