introduction: three-dimensional (3d) scanners are widely used in medicine. one of the applications of 3d scanners is the acquisition of anthropometric dimensions for ergonomics and the creation of an anthropometry data bank. the aim of this study was to evaluate the precision and accuracy of a modified 3d scanner fabricated in this study. methods: in this work, a 3d scan of the human body was o...
abstract this study tried to investigate whether there was any significant relationship between technical translation quality of the senior english translation students and their levels of verbal-linguistic, visual-spatial and interpersonal intelligences. in order to investigate the research questions, the researcher selected a hundred senior english translation students from three universitie...
It is usually believed that the blocking probability of a switching network will increase with the increase of the failure rate of building components (e.g., links, switching elements, etc.) in the switch. In this report, we propose a mathematical model for evaluating the maximum blocking probability of optical banyan networks on vertical stacking when the link failures are considered. Based on...
Cross-sensor comparison experimental results reported here show that the procedure defined and simulated during the Cross-Sensor Comparison Competition 2013 by our team for migrating / upgrading LG2200 based to LG4000 based biometric systems leads to better LG4000-to-LG2200 cross-sensor iris recognition results than previously reported, both in terms of user comfort and in terms of system safet...
In recent years, Information Technology (IT) has grown into a sector that is both as vital and, or possibly even more, resource consuming as Aviation. Combined with our ever-growing dependence of IT, the resulting energy costs as well as the inevitable depletion of materials, such as fossil fuels and rare earth materials, have driven the need for more sustainable solutions, both environmentally...
Cognitive radio (CR) is a technology exploiting knowledge from very diverse fields, such as machine learning, information theory, and wireless communications. The first part of the report introduces state-of-the-art survey on CR. It begins with survey on software defined radio (SDR), since it is the key enabling technology for future development of practical cognitive systems. Because the work ...
In rate-distortion theory it has been shown that vector quantization (VQ) outperforms its counterpart, scalar quantization (SQ), consistently [Shannon, 1959], [GRAY, 1998]. However the major problems that may prevent its wide acceptance in image compression applications is the computational complexity. The VQ compression system is highly asymmetry in that significantly more computing time is re...
