    The water resources structures on the Syrian and Egyptian pilgrim routes to Makka and Medinah

    AI-Hajj in Arabic means the pilgrimage to MAKKA. This was an ancient rite which was recognised a long time before the rise of Islam. According to the holy Quran and Islamic tradi tion, AI-Haj j goes back to the time of the prophet Ibrahim. Thus MAKKA was a focus for worship but it was also a commercial centre and a way station/stopping place on the ancient trade caravan road between south western -Arabia and Bilad AI-Sham,' now Syria. In part the inhabitants of MAKKA practised this trade because their environment was not suitable for other alternative economic activities. The importance of MAKKA, as a ritual place increased after the rise of Islam because it became Qibla-Kiblah - the direction to which muslims turn in praying towards AIKa'aba. Yathrib - later to become Medinah - is the second holy city. In fact it was not a ritual place, but like MAKKA it was a stopping place on the ancient trade caravan road. The inhabitants of Medinah practised agriculture because their environment was more suitable than that at MAKKA; water was available and the land was fertile so that in addition to trade, they also practised agriculture. The importance of Medinah as a holy place only developed after AI-Hijra - the immigration of the prophet Mohammad, peace be upon him, to it and his establishing of Islam at that site. Medinah became the capital of the Islamic state both religiously and politically. Islam then spread from Medinah over the Arabian Peninsular to the world beyond. The consequence of the conquest of Iraq, Bilad AI-Sham, Egypt, the north coast of Africa and Persia was that the majority of the population of these countries accepted and adopted Islam as their religious faith. As a result of this the populations of these countries came annually to make AlHajj and in doing so developed several additional pilgrim caravan routes. However, it is the Syrian and Egyptian pilgrim routes - Tareeq AI-Hajj AI-Shami and Wal Masri which are the objects of this work. In both these cases the pilgrim caravan routes were previously ancient trade caravan routes which travelled through Arabia, particularly through the western province of Al Hijaz. The geographical location of Arabia, the cross roads of three continents, Asia, Africa, and Europe, made important the pre-Islamic routes which ran through it. Of course the function of this network at that time was commercial but after the rise of Islam the function of this network of routes became to transport the pilgrims. The geological and topographical features, as well as climatic conditions, in Arabia played a great role in determining the ancient routes in Arabia. The availability of water was a very important consideration on these routes and was influenced by environmental conditions. Since the rainfall is insufficient, the resulting absence or shortage of water on the pilgrim caravan routes made the caliphs pay great concern to providing the pilgrim routes with the most essential facilities, particularly water supplies and storage. Ever since the earliest Islamic times, they provided for the travellers Al birak, water tanks; Ahwadh cisterns; Qanawat - channels; and abyar - wells, in order to make AI-Hajj journey more comfortable. The pilgrim caravans in general, and the Syrian and Egyptian pilgrim caravan routes in particular, passed through several stages of development since their origin in early Islamic times and these evolutionary stages can be seen until the beginning of this century. Because the object of this thesis is to document the remains of the water resource structures, an extensive survey and investigation has been completed on the Syrian and Egyptian pilgrim caravan routes. The field work has been conducted in Saudi Arabia, particularly in the north western region where the Syrian and Egyptian pilgrim routes cross the country. The field work mainly aimed at ascertaining the location of all the way stations and their names and surveying each station in order to record the surviving remains of water resource structures. The field work covered a large area of about 8, OOOkm transect and extended from MACCA in the south through Medinah to the North as far as Halat I Ammar on the north at the border between Saudi Arabia and Jordan. From N.W. to S .Wit stretched from Haql on the Gulf of AI-' Aqaba as far as MAKKA. These routes consist of the major, or principal caravan routes as well as a number of traverse routes which allow travellers a choice of transit as well as connecting routes. There are large way stations as well as small minor way stations. As part of this dissertation, almost all the stopping places have been identified and documented by mapping and photography

    Finite element analysis of left ventricle motion and mechanical properties in three dimensions / Abdallah Ibrahim Mohammed Hasaballa

    Despite the wide variety of research in medicine and bioengineering treatment strategies developed over the last half century, heart disease remains among the most serious diseases threatening human longevity. Modeling the mechanics of the human myocardium, particularly the left ventricle, which is the main pumping chamber and most common site for heart disease, plays a significant role in better understanding the performance of the heart in healthy and diseased states. The core part of this work constitutes the implementation of a more realistic three-dimensional finite element model of the human left ventricle to provide a reliable description of both myofiber orientation and material characteristics. In this study, direct and inverse finite element methods of human left ventricle were developed. The direct finite element method is suitable for studying the influences of different mesh densities, constitutive models, fibers orientations, and myofiber volume fractions. Meanwhile, the inverse finite element method served to determine the bulk modulus of the left human ventricle during a cardiac cycle. The simulation results indicate that the changes in transverse angle hardly affected the pressure-volume relation of the ventricle, but significantly do so with changes in helix angle (up to 50% change). The ejection fraction decreased with decreasing total volume fraction (increasing the infarct myocardial volume). Total volume fraction of less than 60% deceased the ejection fraction by over 50%. Thus, the myofibers’ architecture plays a significant role in the mechanics of the left ventricle. Finally, the myocardium bulk modulus may be employed as a diagnostic tool (clinical indicator) for heart ejection fraction, and hence, heart function performance. Therefore, this study offers a new perspective and means of studying living-myocardium tissue properties. The research may also pave the way towards more effective treatment

    Self-Regulated Multi-criteria Decision Analysis: An Autonomous Brokerage-Based Approach for Service Provider Ranking in the Cloud

    No full text
    peer reviewedThe use of multi-criteria decision analysis (MCDA) by online broker to rank different service providers in the Cloud is based upon criteria provided by a customer. However, such ranking is prone to bias if the customer has insufficient domain knowledge. He/she may exclude relevant or include irrelevant criterion termed as ’misspecification of criterion’. This causes structural uncertainty within the MCDA leading to selection of suboptimal service provider by online broker. To cater such issue, we propose a self-regulated MCDA, which uses notion of factor analysis from the field of statistics. Two QoS based datasets were used for evaluation of proposed model. The prior dataset i.e., feedback from customers, was compiled using leading review websites such as Cloud Hosting Reviews, Best Cloud Computing Providers, and Cloud Storage Reviews and Ratings. The later dataset i.e., feedback from servers, was generated from Cloud brokerage architecture that was emulated using high performance computing (HPC) cluster at University of Luxembourg (HPC @ Uni.lu). The results show better performance of proposed model as compared to its counterparts in the field. The beneficiary of the research would be enterprises that view insufficient domain knowledge as a limiting factor for acquisition of Cloud services

    The operations of small and medium-sized enterprises (SMEs) occupy an admirable position in the economic landscape of most economies in the world, especially for developing countries. Based on literature review, this paper critically assesses the sources of finance available to SMEs and the difficulties they encounter in accessing these finances. The study identified bank loans, venture capital financing, business angels, trade credit, and government support as the key sources of finance available to SMEs. The study further shows that limited resources, personal characteristics of SMEs managers, and the nature of some SMEs are the common factors inhibiting SMEs access to financ
