Online Implementation Of Structural Analysis Tool For Remote Learning, Ghada El-Mahdy, Amany Micheal Oct 2020

Online Implementation Of Structural Analysis Tool For Remote Learning, Ghada El-Mahdy, Amany Micheal

Civil Engineering

The delivery of a structural analysis module to architectural or civil engineering students needs the visualization of certain diagrams, such as the internal force diagrams and the elastic line. These diagrams are difficult to grasp for students new to structural analysis and need a lot of practice to become proficient in drawing them. Current structural analysis textbooks with electronic platforms do not include tools to draw the internal force diagrams or deflection. This has led to the initiative of creating an online structural analysis tool to enable the student to easily apply different loadings on different statical systems to draw …

Chemical Engineering

A simple, cost-effective and green mucilage-capped silver nanoparticles (Mucilage-AgNPs) modified glassy carbon electrode (GC) composite was constructed for efficient and facile electrochemical oxidation of glucose for the first time. Mucilage-AgNPs were synthesized through the direct chemical reduction of Ag+ by mucilage extracted from Opuntia ficus-indica. Mucilage-AgNPs were identified and characterized using ultraviolet-visible spectroscopy, transmission electron microscopy and square wave voltammetry. Modification of the GC with AgNPs was carried out via a transfer-sticking technique with an immobilization time of 1 h. The Mucilage-AgNPs/GC composite was studied as a possible anode for glucose oxidation in a biofuel cell. The composite resulted in …

Nature Computation Of Self-Adaptive Dynamic Control Strategy Of Population Grouping, Wanlu Ni, Weidong Ji, Xiaoqing Sun

Journal of System Simulation

Abstract: Multi-population optimization method can solve the optimization difficulty caused by the increase of data volume, but the existing population grouping is carried out by means of random grouping or artificial setting, which doesn't take particle trajectories into full consideration. In view of the problem a self-adaptive dynamic control strategy of population grouping is proposed, which uses Gaussian fitting function as the reference curve of population grouping and divides sub populations according to the function's monotone interval. For particles with the trend of crossing the upper boundary of sub populations, the contrarian strategy is adopted to maintain the population diversity …

تأثير الجيل الثالث للثورة الرقميةعلى صياغة تشكيل الكتل المعمارية والعمرانية المعاصرة, محمد وهبه إبراهيم

Architecture and Planning Journal (APJ)

Since the earliest beginning of history, architectural fortresses have acquired varied forms and masses. It was possible to interpret justifications for using many of them; however, usage of some of these forms and masses is still considered as a perplexing mystery for scholars, analysts and interested persons in the topic of mass formulation in architecture. For example, the Giza Pyramids in Egypt which were built 4500 years ago, whose pyramidal mass, which was the output of several astronomic and mathematical relations in the pyramid form, the world is still till our present day analyzing the inherent ideas beyond them.

The Use Of Smart Geomtry In Islamic Patterns A Generative Approach To The Restoration Of The Islamic Urban Areas, Mohammed A. Nasr

Architecture and Planning Journal (APJ)

Geometry is an essential design generator in the Islamic architectural style. Islamic styles are distinct for using the art of geometry in their creative designs. In the Islamic designs, geometry represents the order, harmony and beauty in calculations, scale and proportion. It clearly exists in the design of plans, façade, ornaments and patterns. It expresses many concepts of Islam such as the unity and the oneness of Allah, the perfection and the infinity of creation in the universe, the containments and the continuity. The main proportions of the Islamic style depend on the square proportions(ex: Islamic proportion 1:√2 (Williams, 2006), …

Re-Defining Vernacular Architecturein Third Millennium, Ibrahim Maarouf Oct 2020

Re-Defining Vernacular Architecturein Third Millennium, Ibrahim Maarouf

Architecture and Planning Journal (APJ)

The key purpose of this paper concerns the definition of vernacular architecture in third millennium; a topic which gives the impression of confusion from the beginning when it was a word in the book of Rudofsky. In redefining this term, supplementary conceptual issue will need to be focused briefly and the role of classification will need to be more generally because of an inextricably linked between these two matters. It may seem strange to raise such a basic question again about "What is vernacular architecture?"; because, up till now, it needs to be addressed. There has been a major revitalization …

Architecture and Planning Journal (APJ)

The practice of launching international architectural design competitions to key and important buildings in Egypt is not a new trend. Once built, those award-winning buildings usually undergo a modification process either by their owners or occupants. Owners or occupants always modify these buildings so that their performance would be adapted to certain local parameters. These modifications, however, may touch upon some of the original qualities that had donated those designs merits and recognitions at the time of their selection as prize winners. Many of these significant award-winning buildings might be considered as modern heritage resources, thus developing another layer of …

Re-Humanisation Of The Arab Citiesthe Case Of Alexandria, Egypt, Mohamed Atef Elhamy

Architecture and Planning Journal (APJ)

Urban revolution is bringing about a qualitative transform which can be linked to globalization of economy and of technologies. This in turn makes transformations to the “human face” of city. The traditional Islamic city, with its humanisation features, has a cultural, social, political, economic and ecological logic in terms of physical fabric, layout, and uses. This can provide a lesson for modern planning and design practices. Time has come to re-create the conditions that will restore to the metropolises of today their role as centers of cultural influence and democracy. Fight against intolerance, poverty, injustice, social and cultural exclusion, affirmation …

Towards Adaptive Reuse Of The Industrial Heritage In Minet El-Bassal District At Alexandria, Dina Mamdouh Nassar, Shahira Sharaf Eldin Oct 2020

Towards Adaptive Reuse Of The Industrial Heritage In Minet El-Bassal District At Alexandria, Dina Mamdouh Nassar, Shahira Sharaf Eldin

Architecture and Planning Journal (APJ)

Industrial properties are functional buildings. They are not built to fulfill the aesthetic needs of their users or communities. In urban areas of large cities, they are unlikely to have the privilege of attracting kudos for the communities in which they are situated. In Egypt, and precisely in the metropolitan city of Alexandria, Minet El-Bassal district was once a famous Alexandrian Industrial district. It was built around 1810 overlooking the only seaport in Egypt at that time. It consisted of headquarters of international trading companies, large store-houses, workers housing and "the bourse de cotton" an international marketing center for Egyptian …

Architecture and Planning Journal (APJ)

The objective of this paper is to establish a framework that quantifies land use changes and forecasts urban growth trends. Satellite imageries with moderate resolution (Landsat TM 5 and 7) are used to study the changes in land cover and land uses over a 15 years period (1987 to 2002). Two land use/land cover maps are produced for the two dates, then processed using a two steps Markovian Cellular Automata model. To enhance the projected land use of 2006, socioeconomic preferences and anthropogenic factors are collected and mapped using a raster/vector hybrid geographic information system. The anthropogenic factors are identified …
