Oversampled pyramid decompositions have been successfully applied to scalable video coding. Quantization noise feedback at the encoder (\closed-loop coding") has several advantages compared to \open-loop coding" where noise feedback is not included. Finding optimal bit allocations for closed-loop coders is a complex task since the rate-distortion (R D) performance of one quantizer depends on th...

Background & Objectives: Knowledge-based economy is one of the major parts of the resistance economy and is recognized as the essentials of the information technology age. As one of the most important educational units and the custodian of community health, universities of medical sciences play a pivotal role in the success of resistance economy based on the knowledge-based economy. Among the e...

It has been asserted that temporal subband coding (TSB) is inferior to predictive coding for regionally motion compensated (e.g. block-based MC) temporally scalable compressed video [1]. There are two major disadvantages of TSB coding: temporal ltering distortions, and `open-loop' predictive coding of covered and uncovered regions. The `open-loop' structure of TSB coding, however, a ords two ma...

in many organizations, technology couldn’t improve efficiency and performance. hence in this subject, in-depth and targeted studies are needed to explore successful cases. one of these rare and successful cases is shaparak. shaparak is a new corporation in central bank of iran as a large and public organization that is one of the newest technological proceedings in the central bank. this study ...

nowadays clean energy and technological innovation in this field have becomevery important. dynamic innovation and technology development are done by the formation of technological innovation systems and factors influencing thefunctions of system play a key role in the emergence of such systems.considering the lack of previous researches in this area, this research seeks toanswer the question t...

Visual pattern processing becomes increasingly complex along the ventral pathway, from the low-level coding of local orientation in the primary visual cortex to the high-level coding of face identity in temporal visual areas. Previous research using pattern aftereffects as a psychophysical tool to measure activation of adaptive feature coding has suggested that awareness is relatively unimporta...

this research aims to develop a theory of talent management. the research method is qualitative based on grounded theory. data were gathered in investment market as theoric sampling and 16 interviews were done by managers of investment market. the results of open, axial and selective coding lead to develop dual-core hr architecture theory. based on this theory, organizations should differentiat...

According to the matter of knowledge-based businesses development in economic development and job creation of the state, it is so important to identify effective strategies and factors in developing entrepreneurship, supporting commercializing and branding of knowledge-based businesses and the environment in which these businesses fare formed. The purpose of the present research is offering an ...
