Spatial and socio-cultural dimensions of urban single family houses in Greater Khartoum with Special reference to Hai Alommda

This research investigates the relation between spatial and socio-cultural factors which affects the inhabitant\\\\\\\'s performance of their activities in the house and the relation between them, how it developed, structured and the impact of these factors on the spaces arrangement and usage. Based on the results of 1993 Population Census, it has been recorded that 91.2% of the citizens in...

Characteristics of Radio Wave Propagation Through Trees at 2.1 GHz for UMTS System

This is the final thesis report of M.Sc. research project to study the characteristics of radio wave propagation though vegetation medium at 3G-UMTS frequencies for Middle East type of tress. The excess signal attenuation at 2.1 GHz through Phoenix Date Palm, Conocarpu erectue and Ziziphus Spina Christi trees is investigated though intensive measurement experiments carried out during May-June...

Low Flow Analysis In The River Nile

Characterization of low stream flow is required for both project proponents and regulatory authorities, as water quantity and quality issues are frequently brought to public attention during times of low water availability. This makes it worthy to study the low flows in the rivers of the Sudan and note their characteristics for better management of our resources. This research presents...

Communication in Distributed Systems

The past 1980’s witnessed two advances in technology. The first was the development of powerful microprocessors. The second invention was the high speed local area networks or LANs. These two developments permitted putting together computing systems composed of large numbers of CPUs connected by a high-speed network, thus allowing transfer of information between machines in milliseconds. Such...

Design of MultiProtocol Label Switching Virtual Private Network

The common ways to connect Virtual Private Networks (VPNs) have been through the use of Asynchronous Transfer Mode (ATM) or Frame Relay (FR) or leased link supplied by a service provider. This is increasingly becoming less than ideal solution. The ideal solution is to use A MultiProtocol Label Switching (MPLS). The implementation of VPN using MPLS has several advantages like making routes...

Designing Spreading/Despreading Signals to Enhance Interference Rejection Capability in Direct Sequence Spread Spectrum System

The process gain advantage of a DS system may be compromised when operating in a hostile environment. A determined enemy may render the system inoperative through the use of single tone, multiple tones or swept (chirp) jamming, particularly if the interference frequency is close to the DS carrier frequency. Therefore, some measures should be taken to enhance the inherent interference resistance...

An Investigation of Stability Analyses of the Variable-Frequency Inverter-Fed Induction Motor Drive

This thesis is concerned with an investigation of the results of two important works that have dealt with the steady-state stability of the inverter-fed induction motor drive aiming at the development of user-friendly Matlab programs that will enable a comparative study of the conclusions drawn by the two works. Whereas the first which has been developed in reference [1] is centered on the...

Use of Space Technology in Water Resources Management; case of Gash Basin

Remote sensing techniques have made significant contribution in observing the land use and land cover. Remote sensing data are now capable of enabling the estimation of the changes with very high accuracy. The knowledge of land use changes is essential for food security and for hydraulic study of rainfall-runoff characteristics. The seasonal stream Gash is the source of catastrophic flood for...

Real-Time Scheduling In Multiprocessor Systems

As a result of the development of computing, especially in automotive market and other fields, the standard uniprocessor microcontroller architecture will not be able to support the needed computing power even taking into account the IC technology advances. To increase computational power, multiprocessor real-time systems introduced. Scheduling algorithm used in some applications like UNIX...
