The sectors of energy and scientific research were mentioned Saturday by the governor of central Huambo province, Albino Malungo, as some of the priorities in the implementation of development programmes in the region.
With President Bush in virtual hiding through Election Day, it was up to Vice President Cheney and first lady Laura Bush to pick up the slack on the campaign trail.
For years, advocates of agricultural biotechnology have promised a future in which foods will be genetically engineered to give more nutrition and to prevent chronic diseases, in which crops will be modified to thrive in salty soil or hot or
In two recent speeches that have attracted little notice, Donald Kerr, principal deputy director of national intelligence, has called for a radical new relationship between government and the private sector to counter what he called the "malicious activity in cyberspace
Odessa—On 30 October, a scholarly-practical conference "Ukraine and the Vatican in the Development of Higher Education" was held in The Christian Humanitarian and Economic University in Odessa.In particular, a report by Yurii Reshetnikov a candidate of Philosophic Sciences, dealt with
The increase coincided with residential development in the Big Darby watershed, and could be caused by a combination of road salts draining into the creek and other effects of a growing human population in the area, researchers suggest.
A recent study by researchers at Ohio State University and National Park Service found that higher deer activity is modifying forest ecosystems in unexpected ways. Out of several species of snakes, salamanders, and invertebrates studied, a greater diversity of animals
The Alton College Drama & Theatre Studies department will be presenting an exciting and varied collection of plays, performed by the department's AS students.
In WiMAX/IEEE 802.16 with mobility support, the network entry procedure for a mobile station involves several steps including the scanning for an available channel and performing initial ranging in order to determine power and timing offset requirements. These steps are
With the advancement of wireless technology and the increasing demand for mobile devices, secure and efficient password authenticated key establishment technologies are needed for various kinds of secure communications among wireless devices. In this paper, we propose a simple and
An algorithm for self-organisation that assigns the channels intelligently in multi-radio wireless mesh networks (MR-WMN) is important for the proper operation of MR-WMN. The aim of the self-organisation algorithm is to reduce the overall interference and increase the aggregate capacity
In this paper we study the performance of TCP with a vertical handoff between access networks with widely varying link characteristics. TCP being an end-to-end protocol has performance problems as its behaviour depends on the end-to-end path properties which are
Unlike traditional routing procedures that, at the best, single out a unique route, multi-path routing protocols discover proactively several alternative routes. It has been recognised that multi-path routing can be more efficient than traditional one mainly for mobile ad hoc
The paper is concerned with developing energy balancing cooperative diversity schemes for wireless sensor networks in a Rayleigh fading environment. In the network scenario we consider, the network is composed of a bottleneck node (BN) - for which energy consumption
This paper proposes an architecture, namely Arch-AdSenNets, for inter-working mobile ad-hoc networks (MANETs) with wireless sensor and actor networks. We lay out requirements, discuss possible solutions and propose a network model within Arch-AdSenNets for the collaboration of MANET nodes and
We establish rigorous foundations to the use of modular and layered design for building complex distributed systems, resilient to failures and attacks. Layering is a key to the design of the internet and other distributed systems. Hence, solid, theoretical foundations
