This protocol controls telephony gateways from external call control elements called media gateway controllers or call agents. Converting among the audio signals carried on telephone circuits and data packets carried over the Internet or over other packet networks is done by telephony gateway. According to the call control architecture assumption of the MGCP the call control intelligence is outside the gateways and handled by external call control elements and these call control elements, or Call Agents, will synchronize with each other to send ....etc

GLOBAL WARMING AND ISSUES


Global Warming will be the greatest environmental challenge in the 21st century

Global warming - effect on the climate of human activities, in particular the burning of fossil fuels (coals, oil and gases) and large-scale deforestation, which causes the emission of green house gases e.g. carbon di oxide, emission to the atmosphere.

The global temperature of earth’s atmosphere is raised due to increased inputs of carbon dioxide ....etc

Global Issues: Ozone Depletion, Global Warming and Acid Rain

Introduction

Air pollution is exerting increasing impact on the environment. Humans have been altering the chemistry of the atmosphere on a global scale. These changes may:
Modify the global climate
Threaten the health of human beings
Create many environmental problems such as
Acid rain
Depletion of ozone layer
Global warming
Seriously upset the global ecosystem

What is ozone depletion?

Ozone is a highly reactive gas comprising ....etc

Global Issues

Everyday radios, newspapers, televisions and the internet warn us of energy exhaustion, atmospheric pollution and hostile climatic conditions. After few hundred years of industrial development, we are facing these global problems while at the same time we maintain a high standard of living. The most important problem we are faced with is whether we should continue developing or die.

Coal, petroleum, natural gas, water and nuclear energy are the five main energy sources that hav ....etc

The Megaco protocol is used between elements of a physically decomposed multimedia gateway and is the result of cooperative efforts of the IETF and the ITU-T Study Group 16. The protocol definition of this protocol is common text with ITU-T Recommendation H.248. There are no functional differences from a system view between a decomposed gateway, with distributed sub-components potentially on more than one physical device, and a monolithic gateway such as described in H.246 . The Packet network interfaces may include IP, ATM or possibly ot ....etc

high speed protocol processor to boost gateway performance


Abstract
high-speed protocol processor for gateways based on the concept normal data transfer is executed by special-purpose hardware and a general-purpose microprocessor handles abnormal data transfer and connection control. To analyze the quantitative effect of this proposal, a high-speed protocol processor which can execute OSI (open systems interconnection) layers two to four was manufactured, and its performance was measured. The protocol processing time for normal data trans ....etc

Abstract

Auctions are among the Latest economic institutions in place. They have been used since antiquity to sell a wide variety of goods, and their basic form has remained unchanged. In this dissertation, we explore the efficiency of common auctions when values are interdependent- the value to a particular bidder may depend on information available only to others-and asymmetric. In this setting, it is well known that sealed-bid auctions do not achieve efficient allocations in general since they do not allow the information held by d ....etc
