Original scientific paper Nowadays computerization is the most popular, reliable and flexible design for various types of control and communication systems. Sound navigation and ranging (SONAR) is a modern ultrasonic range finding technique used for collecting the information of a distant object without any physical contact. In this paper, a personal computer (PC) based active SONAR system is p...

A musical performance within Western classical music typically consists of the combined artistic contribution of the composer and the performer. The composer’s part, the score, has long been studied and scrutinized in terms of its structural aspects such as harmony, melody, form, instrumentation, as well as of studying the composer’s intention or the inherent emotional expression (Hevner, 1937)...

Localization performance and spatial hearing abilities of blind persons are complex issues. In everyday life we rely on the “fact” that blind people can hear better, without thinking of what “better” means. Localization performance depends on many parameters such as properties of the excitation signal, environmental conditions, individual aspects, and visual influence. Our goal was to create a ...

This article examines the functions of prank performance and troll performance for the aesthetics of personal live-streaming, i.e. the practice of live-streaming one’s personal performance via platforms such as Twitch.tv. The study is based on a close analysis of personal esport live-streamer Ali Larsen, aka Gross Gore, via a 12-month observation period. With help of Goffmanian frame theory the...

Current trends in mobile robotics involve many small yet surprisingly computing-intensive tasks combined in one complex application. While the use of just one personal computer is insufficient in terms of computing power and reliability, the small dimensionality of each of the application’s tasks does not justify supercomputers use. In addition, as more and more robotics laboratories across the...

Purchases of computers, software, and communications equipment grew rapidly during the 1990s, representing an increasing share of total U.S. investment spending over the course of the decade. Using official statistics from the U.S. Bureau of Economic Analysis (BEA), nominal investment expenditures for three categories—computers and peripheral equipment, software, and communications equipment—ro...

With the invention of the microprocessor circa 1970, humanity was catapulted into the Information Age. Following Moore’s Law, the microprocessor has essentially doubled in complexity, capacity, and capability every two years since that time. As a result, today’s personal computer is vastly more powerful than the mainframe supercomputers of decades past. This radical increase in computing power,...

The field of microelectronics has had a profound impact on both the scientific world and on our personal lives. Through astonishing advances in performance, microprocessors have replaced traditional mainframes and supercomputers with microprocessor-based workstations and servers. The remarkable decrease in cost vs. performance for microprocessors has made computing ubiquitous, putting web-conne...

This article concerns on overview of today software products for ordinary personal computers and small workstations, gives list of important features relevant to solution of environmental foresighting. For this branch of problems are important not only usual advantages of software packages like computing power, simplicity of use, number of prepared models, but in the first place multidisciplina...
