Overview Of Technical Solutions Research Articles

ТЕПЛОВЫЕ ТРУБЫ В АТОМНОЙ ЭНЕРГЕТИКЕ

The paper provides an overview of technical solutions for using of heat pipes in nuclear power plants both developed and operating. The review based on the scientific, technical and patent literature shows wide application heat pipes as heat transfer devices. Using of them for small and super-small power plants seems to be especially effective, because of high specific cost of plants with circulating coolants. A heat pipe is a device transferrind the heat by means of evaporation and condensation of a coolant circulating automatically under the action of capillar or gravitation forces. Heat pipes are used rather widely, both abroad and in Russia. The first application of a heat pipe principle in nuclear power plants was published in 1957, even before the emergence of the term "heat pipe". Now, there are about 300 patents in the world related to heat pipes application in nuclear power plants. Theare are seweral thouthands articles on the development of nuclear reactors with heat pipes have been published in the scientific and technical literature. One should expect that fifth-generation nuclear reactors cooled by heat pipes without any mechanisms and machines for the circulation of the coolant, as well as without the consumption of mechanical and electrical energy, will be appeared in this decade.

Overview of technical solutions and assessment of clinical usefulness of capsule endoscopy.

The paper presents an overview of endoscopic capsules with particular emphasis on technical aspects. It indicates common problems in capsule endoscopy such as: (1) limited wireless communication (2) the use of capsule endoscopy in the case of partial patency of the gastrointestinal tract, (3) limited imaging area, (4) external capsule control limitations. It also presents the prospects of capsule endoscopy, the most recent technical solutions for biopsy and the mobility of the capsule in the gastrointestinal tract. The paper shows the possibilities of increasing clinical usefulness of capsule endoscopy resulting from technological limitations. Attention has also been paid to the current role of capsule endoscopy in screening tests and the limitations of its effectiveness. The paper includes the author’s recommendations concerning the direction of further research and the possibility of enhancing the scope of capsule endoscopy.

Virtual and Remote Laboratories in Process of Control Education

This paper describes the progress in the development of virtual and remote laboratories at Department of Information Engineering and Process Control, FCFT STU in Bratislava. Article is the overview of technical solutions used for online education purposes. These comprise software technologies, most commonly used in virtual and remote laboratory design at our department, as MATLAB Web Server, Java, C/C++, and Adobe Flash. We have created virtual laboratories as online Web applications, which provide features of mathematical computing and simulations of technological plants. We also describe a technology of remote control laboratory with a real experimental device.
