|Diierentiated services for the Internet are undergoing intensive development. It is widely accepted that they will require usage sensitive pricing. The Paris Metro Pricing (PMP) proposal is to rely on pricing alone to provide diierentiated services. PMP is the simplest diierentiated services system in terms of complexity.

We report on an emerging application focused on the design of resilient long reach passive optical networks using combinatorial optimisation techniques. The objective of the application is to determine the optimal position and capacity of a set of metro nodes. We specifically consider dual parented networks whereby each customer must be associated with two metro nodes. An important property of ...

In this globalization era, companies are required to keep learning and changing. In the process of changing, companies need to be adaptive and innovative. Therefore, a company needs to cultivate and maintain its knowledge. Among other ways, it can be achieved by encouraging the process of knowledge sharing within the company. Hence, this study aims to know the perception of the employee regardi...

Globally, HIV/AIDS remains one of the most serious public health challenges, with 33 million people infected in 2008, of which 5.7 million were living in South Africa.1 KwaZuluNatal is the leading province in South Africa where HIV/ AIDS is concerned, with 1.6 million people infected with the disease.1 Since the introduction of highly active antiretroviral treatment (HAART), a significant impro...

Mr. Vukan R. Vuchic deals with the latest developments of metro networks and with their future state in the 21st century. He recalls the basic characteristics of metro and the positive and stimulating role it can play in large cities. While its first networks were opened more than a century ago, metro still knows an important growth: for example, it is the best adapted means of transport in som...

the main tasks of ‘environmental graphics’ have been designated as: provision of instructions and essential information, environmental embellishment, ease of interconnection and visual identity establishment all of which can affect the culture and identity of the audience through an unconscious process. if we consider, on the one hand, the crisis of identity and cultural problems of the present...

This paper is designed to study the role of multispecialty hospitals in improving healthcare system economy. The based with special reference METRO Hospital Shimoga. done assess types and components technology used hospital which has helped lots patients their saved lives. aims understand nature growth market structure Healthcare Sector, know recent trends present scenario, opportunities challe...

positive impact metro cell antennas with narrow vertical beamwidth and electrical downtilt can have on heterogeneous cellular networks. Using a model of random cell placement based on Poisson distribution, along with an innovative 3D building model that quantifies blockage due to shadowing, it is demonstrated that network spectral efficiency and average user throughput both increase as vertical...

This study reviewed the mechanics for the Adoption of Information and Communication Technology for Agricultural Productivity among Rural Farmers in Nigeria. Information and Communication Technology is a concept that has become globally appreciated. It has made the world to assume a village status. One will at his/her convenience monitor the events that happen all over the world, via the interne...
