Cognitive interconnections

Introduction. Originally conceived as a non-commercial infrastructure, the Internet has gradually morphed into the largest ‘connectivity machine’ ever built. Business, entertainment, social life and politics are heavily reliant on the Web, which in turn requires a fully-operational network. Yet, unlike any other complex machine, the Internet has not been built with the knowledge of what it was later supposed to be doing. So now, many worry that it will fail under the strain of time- and dataintensive applications. HD Video, Cloud Services and the Internet of Things are already making this issue apparent. What will happen when new applications that are not yet in sight emerge? In this lecture I will explain why the time is ripe for a complete overhaul of the net, highlighting its actual flaws. I will discuss the network mechanisms that will help to shape the next-generation Internet, focusing on the prospects and hurdles of ‘cognitive’ networking

Analysis of pervasive mobile ad hoc routing protocols

Pervasive computing (also referred to as ubiquitous computing or ambient intelligence) aims to create environments where computers are invisibly and seamlessly integrated and connected into our everyday environment. Pervasive computing and intelligent multimedia technologies are becoming increasingly important, although many potential applications have not yet been fully realized. These key technologies are creating a multimedia revolution that will have significant impact across a wide spectrum of consumer, business, healthcare, and governmental domains. This useful volume provides up-to-date and state-of-the-art coverage of the diverse topics related to pervasive computing and intelligent multimedia technologies. The use of different computational intelligence-based approaches to various problems in pervasive computing are examined, including video streaming, intelligent behavior modeling and control for mobile manipulators, tele-gaming, indexing video summaries for quick video browsing, web service processes, virtual environments, ambient intelligence, and prevention and detection of attacks to ubiquitous databases. Topics and features: -Includes a comprehensive overview, providing a thorough literature review and an outline of the important research challenges -Discusses pervasive computing approaches in the context of intelligent multimedia -Examines virtual reality technology, mobile virtual environments, and the potential use of intelligent multimedia and ubiquitous computing in the hotels of the future -Describes various approaches in ambient intelligence for home health care for the elderly and those suffering from Alzheimer’s disease, for volcano monitoring, and for preventing attacks to ubiquitous databases Investigates issues in web services and situation awareness in pervasive computing environments -Explores wireless network applications, such as mobile agents and e-commerce

Shell corrections for finite depth potentials: Particle continuum effects

Shell corrections of finite, spherical, one-body potentials are analyzed using a smoothing procedure which properly accounts for the contribution from the particle continuum, i.e., unbound states. Since the plateau condition for the smoothed single-particle energy seldom holds, a new recipe is suggested for the definition of the shell correction. The generalized Strutinsky smoothing procedure is compared with the results of the semi-classical Wigner-Kirkwood expansion. A good agreement has been found for weakly bound nuclei in the vicinity of the proton drip line. However, some deviations remain for extremely neutron-rich systems due to the pathological behavior of the semi-classical level density around the particle threshold.Comment: 18 pages, 8 figure
