Proposed article analyses dependence of MOS as a voice call quality (QoS) measure estimated through ITU-T E-model under real network conditions with jitter. In this paper, a method of jitter effect is proposed. Jitter as voice packet time uncertainty appears…

SIP PBX is definitely the alpha and omega of any IP telephony infrastructure and frequently also provides other services than those related to VoIP traffic. These exchanges are, however, very often the target of attacks by external actors. The article…

The Reactive power flow’s is one of the most electrical distribution systems problem wich have great of interset of the electrical network researchers, it’s  cause’s active power transmission reduction, power losses decreasing, and  the drop voltage’s increase. In this research…

The article gives a review of a research on processing and automatic recognition of speech signals (ARR) at the Department of Telecommunications of the Faculty of Electrical Engineering, University of iilina. On-going research is oriented to speech parametrization using 2-dimensional…

Dynamic changes in traditional technologies and rising of new technologies call for development of new services. If service providers want to stay on information technologies market, they must keep track with this trend and adjust their services to customer requirements…

X-ray diffraction analysis indicated that the all silicon films are polycrystalline. The preferred orientation of silicon films deposited on SiAlON is almost i [110] direction perpendicular to substrate, whereas the preferred orientation of the silicon films deposited on mullite and…

The gait analysis history brought a lot of methods and methodologies. It became a standard to collect data and create databases of human gait characteristics. One of the reasons is to derive standard deviations to be able compare patients’ data.…

Information and communication technologies (ICT) affect all aspects of life, in the time of technical progress there are also special assistive devices developed that makes the daily life easier. The use of the ICT is rapidly becoming an essential part…
