In this paper, a two-dimensional (2D) rate model is proposed considering the joint impact of spatial (i.e., the frame size) and SNR (i.e., the quantization step) resolutions on the overall rate-distortion performance. A related 2D quality model is then pr... see more

Spread spectrum adalah sebuah metode komunikasi dimana semua sinyal komunikasi disebar di seluruh spektrum frekuensi yang tersedia. Sinyal informasi akan ditebarkan pada seluruh pita frekuensi yang disediakan dan dilakukan secara acak. Metode spread spect... see more

The aim of this study was to evaluate the reject rate of periapical and bitewing radiographs among dental undergraduate students of Universiti Kebangsaan Malaysia (UKM), identify the type of radiographic errors which are frequently encountered and compare... see more

Beam wandering is the main cause for major power loss in laser communication. To analyse this prerequisite at our environment, a 155 Mbps data transmission experimental setup is built with necessary optoelectronic components for the link range of 0.5 km a... see more

Context. Factorial data coding allows combining operations of cryptographic protection, intentional alteration of data, and errorcorrecting coding which leads to the decrease of redundancy introduced by transmitter and to the increase of data rate and eff... see more

The objective of this study was to investigate the drying characteristics and kinetics of red pepper and bitter leaf under the influence of different drying temperatures. The drying experiments were carried out at dry bulb temperature of 35, 45, 55 and 75... see more

Turbo codes are the error-coding schemes applied nowadays in wireless networks. In navalapplications, the information is mostly sent through wireless networks and the data is moreprone to noise. Since very important data has to be communicated, it is nece... see more

Context. The analysis of reliability indicators of information transfer between elements of wireless control systems – a control device implemented on a smartphone and a communication processor of the developed hearing aid is carried out. The object of re... see more

Context. The reliability indicators of information transmission between control systems elements, taking into account the packaging(grouping) of errors in the communication channel, are analyzed. The research object are the characteristics and parameters ... see more
