Cloud computing has become one of the leading technologies in world today. The benefits cloud affect end users directly. There are several frameworks, and each ways monitoring providing resources. eliminates customer requirements such as expensive system configuration massive infrastructure while improving dependability scalability. From user’s perspective, makes it easy to upload multiagents o...

Complex networks have been successfully employed to represent different levels of biological systems, ranging from gene regulation to protein-protein interactions and metabolism. Network-based research has mainly focused on identifying unifying structural properties, such as small average path length, large clustering coefficient, heavy-tail degree distribution and hierarchical organization, vi...

In previous work we have identified the problem of dimensionality associated with learning the data density distributions of textures. In this document we investigate the properties of a family of ways of constructing this space, based upon approaches which have demonstrated merit in the recent literature. We find that for Martian images at least there seem to be advantages to the strategy of e...

This article addresses basic issues regarding the design and development of wireless access and wireless LAN systems that will operate in the 60 GHz band as part of the fourth-generation (4G) system. The 60 GHz band is of much interest since this is the band in which a massive amount of spectral space (5 GHz) has been allocated worldwide for dense wireless local communications. The article give...

In this paper we present a study conducted within the framework of an inservice professional development program for junior and senior high school mathematics teachers. The focus of the study is the analysis of processes encountered by the staff members, as members of a community of practice, which contributed to their growth as teacher educators. We offer a three-layer model of growth through ...

For a fast return of investment, network providers have to offer new services for the upcoming 3G mobile communication systems. Unfortunately 3G systems suffer by high installation costs and low quality of services in terms of high delays and low bandwidth. These drawbacks exclude many promising services such as real–time video conferences and multi– player gaming. Furthermore, high network ins...

We propose a calculus, cCOA, combining, thus more expressive than each of, two orientation calculi well-known in QSR: Frank’s projection-based cardinal direction calculus, CDA, and a coarser version, ROA, of Freksa’s relative orientation calculus. An original constraint propagation procedure, PcS4c+(), for cCOA-CSPs is presented, which aims at (1) achieving path consistency (Pc) for the CDA pro...
