One of the important features of ATM networks is their ability to support multicast communications. This facilitates the efficient distribution of multimedia information streams (such as audio and video) to large groups of receivers (potentially millions). Because ATM networks do not provide reliable delivery mechanisms, it is up to end systems to provide end-to-end reliability where it is need...

abstract background: the pancreatojejunostomy has notoriously been known to carry a high rate of operative complications, morbidity and mortality, mainly due to anastomotic leak and ensuing septic complications. objective: in order to decrease anastomotic leak and its attendant morbidity and mortality in operations requiring a pancreato-jejunal anastomosis, and also in order to simplify the ope...

abstract background: end-to-side esophagojejunostomy has almost always been associated with some degree of dysphagia. to overcome this complication we decided to perform an end-to-end anastomosis and compare it with end-to-side roux-en-y esophagojejunostomy. methods: in this prospective study, between 1998 and 2005, 71 patients with a diagnosis of gastric adenocarcinoma underwent total gastrect...

Inspired by the context of compressing encrypted sources, this paper considers the general tradeoff between rate, end-to-end delay, and probability of error for lossless source coding with side-information. The notion of end-to-end delay is made precise by considering a sequential setting in which source symbols are revealed in real time and need to be reconstructed at the decoder within a cert...

Duty-cycle MAC protocols have been proposed for wireless sensor networks (WSNs) to reduce the energy consumed by idle listening, but they introduce significant end-to-end delivery latency. Several works have attempted to mitigate this latency, but they still have a problem on handling the packet loss. The quality of the wireless channel in WSNs is quite bad, so packets are frequently lost. In t...

Wireless sensor networks are required in smart applications to provide accurate control, where the high density of sensors brings in a large quantity of redundant data. In order to reduce the waste of limited network resources, data aggregation is utilized to avoid redundancy forwarding. However, most of aggregation schemes reduce information accuracy and prolong end-to-end delay when eliminati...

In wireless sensor networks, secure data aggregation protocols target the two major objectives, namely, security and en route aggregation. Although en route aggregation of reverse multi-cast traffic improves energy efficiency, it becomes a hindrance to end-to-end security. Concealed data aggregation protocols aim to preserve the end-to-end privacy of sensor readings while performing en route ag...

The current development of global economies and societies is regarded as being highly unsustainable. This paper analyses the current situation. Instead of simplistic metrics that take only snapshots of the life-cycle of a product into consideration, an approach is introduced that covers the whole supply chain. The core idea is that end-to-end transparency, specific data models, a process archit...

This is the era of big-data: high-volume, high-velocity and high-variety information assets are being collected, demanding cost-effective information processing. Analytic techniques primarily based on statistical methods are showing astonishing results, but exhibit also limited reasoning capabilities. On the other end of the spectrum the era of bigreasoning is emerging with next-generation cogn...
