Nima Nematzadeh, Zahra Abedi and Farideh Atabi

Abstract:
In this project, we are about to investigate one of the most important methods for reducing fuel consumption and the following pollution caused by automobile. Fuel consumption of automobiles and diffusion of pollution into the air have a direct relationship with shape of car body. Previous studies suggest that the most part of engine power is consumed to overcome the friction caused by the aerodynamic property. As a result, it is very important to design the automobile in the optimized manner so as to reduce the air resistance force. In this project, setting a basic bus as platform, a modified bus is designed and two maquettes were built for the both buses. Then several tests were carried out by placing them inside wind tunnel. Next, in order to validate and simulate the model, geometries of the buses were mapped using Catia software. Gambit software was also utilized for meshing. Finally, simulation process was carried out using CFD in Ansys software. Applying some modifications to the roof, floor, air chamber, and side mirrors, drag coefficient reduced to 47%, and fuel consumption was also decreased to the range of 0.56 to 13.78 liter per hour.
Keywords: Exterior view of bus, Aerodynamic covering, Simulation, Drag coefficient.

Majid Nasiri and Mahboubeh Zarezadeh

Abstract:
Facility layout depends on the arrangements of work centers, productive and service sectors of organizations. In this research, a number of research permutations are represented and through the intertextual utilization of particle swarm optimization algorithm (PSO) and genetic algorithm, a number of research samples are tested and deducted. Furthermore, C programming language and Net 2010 and Microsoft Visual software applications are utilized. A series of distinct processes are appointed for each PSO algorithm and genetic algorithm. Such distinct processes materialize the opportunity for software applications to utilize two distinct procedures simultaneously in real time. In this research, scholarly preference of PSO algorithm over genetic algorithm is apparent due to id precision and efficiency.
Keywords: Layout, Limited Permutation Algorithm, Particle Swarm Optimization Algorithm (PSO), Genetic Algorithm.


Examining the Relationships of the Warehouse Inventory of Food Factories using the Integrative Cognitive Maps Method and the Systems Approach (Case Study: The Chitoz Potato Chips Factory)

49-59
Mostafa Kazemi and Mahboubeh Zarezadeh

Abstract:
A warehouse is a place where one or more than one type of commercial and industrial goods, raw materials or various products are properly stored and categorized based on a certain system. Trade is based on purchasing and selling goods by commercial institutes in every country. Therefore, warehouse inventory makes up the majority of capital in commercial companies, and warehouses are considered one of the main elements of trade. As environmental impacts are further complicated, one-dimensional shallow decisions cannot solve multidimensional and complicated problems ahead of organizations. Managers should be equipped with an effective tool in order to be able to tackle such problems. The systems approach can greatly help managers to better understand and solve problems ahead of organizations. The cognitive map is a process in which a network of the factors and relationships of a complicated phenomenon could be presented in the form of a map or a diagram. This process could also indicate how a system operates. The current paper examines the relationships of the warehouse inventory of the Chitoz Potato Chips Factory using the integrative cognitive map method and the systems approach.

The Humanities in Engineering Education: An Islamic Approach
92-99
Mohd Nuri Al Amin Endut and Zawawi Ismail

Abstract:
The role of the engineer should not be regarded as a purely technical or mechanical profession. Engineers are actually taking on an important societal role to shape and even ‘design’ society’s way of life, just as much as the engineer has the ability to design his or her projects. Thus for potential Muslim engineers, it is significantly important for Muslim engineering students not only to be aware of their social and professional responsibilities, but also to be more critical of the religious impact inflicted by their design projects. As such they should be exposed to a holistic engineering education that also emphasizes religious conceptual thought rather than solely focusing on technical based knowledge. In short, universities in Islamic countries should be more concerned on the effect of western critical thinking, which puts aside religious consciousness and motivation from its views and theories, on the perception of Muslim students. Alternatively tertiary education should consider introducing the Islamic perspective of engineering that has its own philosophical and psychological concept in shaping the students’ thought. This paper focuses on the importance of the humanities aspect in engineering education especially from the Islamic perspective. It will also reveal the need for promoting Islamic conceptual thinking to Muslim engineering undergraduates in order to contribute not just to Muslim societies, but to humanity at large.
Keywords: Engineering education, humanities, Islamic education, spirituality, tertiary education.

Abstract:
La variabilité de la mousson Ouest africaine a eu des conséquences socio-économiques et environnementales sur les populations. Cette variabilité est intimement liée à la circulation atmosphérique, qui d’ailleurs joue un rôle dominant dans l’organisation de la mousson. Les présents résultats expérimentaux renseignent sur la dynamique des vents à travers les caractéristiques des jets. Les données proviennent d’un radar VHF profileur de vent installé au Bénin, précisément à Nangatchori (9°6472N, 1°7411E) au cours de la campagne de mesures du programme AMMA (2006-2007). Cette étude montre la présence du Jet d’Est Africain (JEA) dans la troposphère moyenne (2-4 km). Elle montre, en outre, la présence du Jet d’Ouest Subtropical (JOST) et du Jet d’Est Tropical (JET) dans la haute troposphère (10 km). Les profils obtenus laissent distinguer de façon remarquable deux grandes saisons caractérisant l’OHHVO (Observatoire Hydrométéorologique de la Haute Vallée de l'Ouémé). La CAH (Classification Ascendante Hiérarchique) appliquée aux vitesses moyennes et fréquences de direction du vent à 10 km d’altitude associées au cumul mensuel de pluie confirme l’existence des deux grandes saisons : une saison sèche (novembre à mars) et une saison humide (avril à octobre). La saison humide est caractérisée par trois phases: la phase pré-humide (avril, mai, juin), le cœur de la saison humide (juillet, août, septembre) et la phase post-humide (octobre).
Mots clés: Jets, mousson Ouest-africaine, circulation atmosphérique, Bénin.
