IPTV based on full-duplex networks potentially provides much richer media experiences than traditional TV. However, video contents compressed with non-scalable coding schemes greatly constrain the potential. This paper proposes a new IPTV architecture, which fully takes the advantages of scalable video for adaptation to both networks and devices. Firstly, network adaptation is mainly performed ...

A short hospital stay is one of the main advantages of the laparoscopic surgical technique. The process of developing and studying the "fast-track" process has contributed to a better understanding of the elements of perioperative care and has resulted in the reduction in length of stay (LOS) after colectomies. As we follow and refine this well-recognized multimodal approach, further decreases ...

In this paper, we propose a novel hardware caching technique, called switch directory, to reduce the communication latency in CC-NUMA multiprocessors. The main idea is to implement small fast directory caches in crossbar switches of the interconnect medium to capture and store ownership information as the data flows from the memory module to the requesting processor. Using the stored informatio...

Smart home (SH) services promote the comfort, convenience, security, entertainment, healthcare, education and communication of people in their home environments. Despite radical enhancements envisioned to peoples’ lives, the SH market has remained a niche for more than three decades. Yet, recent fast-paced developments, including ubiquitous computing, miniaturization of microelectronic componen...

The technique of Interferometric Synthetic Aperture Radar can generate high precise Digital Elevation Model (DEM) fast, which makes it play a very important role in the development of social economy and construct of national defense. Once the high precise DEM can be acquired in real-time, the worthiness of the technique will be embodied fully. In this thesis, the research dynamic of generating ...

Background: The growing prevalence of chronic diseases in children has increased their need for palliative care. We aimed to compare pediatric palliative care and home care training in Iran and in the selected countries. Materials and Methods: This comparative study was conducted based on the classifications of palliative care for children and using databases such as Scopus, Science Direct, Ovi...

CONTEXT Systematic conservation planning is increasingly used to identify priority areas for protection in marine systems. However, ecosystem-based approaches typically use density estimates as surrogates for animal presence and spatial modeling to identify areas for protection and may not take into account daily or seasonal movements of animals. Additionally, sympatric and inter-related specie...

BACKGROUND There is a popular belief that out-of-home eating outlets, which typically serve energy dense food, may be more commonly found in more deprived areas and that this may contribute to higher rates of obesity and related diseases in such areas. METHODS We obtained a list of all 1301 out-of-home eating outlets in Glasgow, UK, in 2003 and mapped these at unit postcode level. We categori...

Despite the growth in empirical research on neighborhood environmental characteristics and their influence on children's diets, physical activity, and obesity, much remains to be learned, as few have examined the relationship between neighborhood food availability on dietary behavior in children, specifically. This analysis utilized data from a community-based, cross-sectional sample of childre...
