Building an Installation Artwork: Casting Light to Transform the Shapes of Printed Silk Screen to Be Part of the Space
Printmaking often includes a two-dimensional frame whether it was printed out on paper or canvas. In the time when most artist strive to create new forms of art whether it was in sculpting, drawing, painting so on and so forth, printmaking is still considered a traditional form of art limited to its frame. In an attempt to make a quantum leap in the concept of artistic works’ dimensions this research aimed to investigate a method which aids extracting the work of art from its limited frame. where lighting helps to free the shapes of the artwork and make them part of the surrounding atmosphere, a part of space. This was achieved by three artworks which were printed on plates of hardened glass; thus, each artwork is a set of layers that when merged together would create the final form of the artwork. Also, a paper copy of each artwork was made. Light was added to these artworks allowing the receivers to walk through the artwork instead of rotating around it, thus, participating into the artwork itself

Tectonics and mineralization of Wadi Allaqi, south Eastern Desert, Egypt
A thesis submitted to the Faculty of Science & Computing, University of Luton, in partial fulfilment of the requirements for the degree of Doctor of Philosophy. Collaborating Institution: Egyptian Geological Survey and Mining Authority.Neoproterozoic volcanic, sedimentary and volcano-sedimentary rocks of central Wadi Allaqi were deformed and metamorphosed to greenschist facies during the Pan-African orogeny. Three major, geochemically and lithostratigraphically distinct, tectonic-stratigraphy Successions with an intermediate tectonically-emplaced unit of ophiolitic rocks (Gebel Taylor Wedge), which have been metamorphosed to blueschists facies prior to emplacement, are recognised. The tectonic pile has been intruded by four granitic plutons and basic igneous sills, which were emplaced at various stages in the tectonic history. A series of large-scale thrust duplexes with a few major nappe-like folds and shear-zones, the most conspicuous of which is the Allaqi Shear-zone, structurally dominate the area. A complex polyphase structural history has been deduced consisting of earlier ductile and late more brittle deformation phases and this has been related to the regional metamorphic development. A gold mineralized quartz vein system was emplaced syn-tectonically along the first deformation (D1) shear-zones. Data from structures, petrography, fluid inclusions and stable isotopes of oxygen and hydrogen tend to support a metamorphic provenance for the auriferous fluids. The petrological, geochemical and structural evidence strongly support a back-arc basin environment for the sedimentary development of central Wadi Allaqi before the Pan-African Orogeny. A single Wilson Cycle is proposed for the evolution of the area, in which following an extensional phase, during which the marginal elements of the ancient Mozambique Ocean (in the sense of Dalziel 1991) were developed. Back-arc sedimentary rocks and volcaniclastic rocks were metamorphosed and transported as a thrust-duplex system northward over the Nile Craton and any associated marginal sedimentary sequence

توصلّ البحث الى تطابق بعض التقنيات الرقمية لتوظيف المعلومات في BIM ضمن معايير الدول الأربعة، والمتمثلة بأساليب الخزن والتنظيم الرقمي للمعلومات، واساليب الامن الرقمي، واساليب التكامل والتشغيل البيني للمعلومات، بحيث يمكن اعتمادها في المعيار العراقي بوصفها أساليب مشتركة عالمياً. بينما تتباين هذه الدول في أساليب هيكلة البيانات التصميمية، وأساليب خزن قاعدة البيانات المتمثلة بالمكتبة الوطنية، واساليب تنسيق وتصنيف وتمثيل المعلومات (التسمية والمصطلحات)، مما يشير الى خصوصية كل دولة في تطبيقها للنظام، وعليه يتوجب توظيفها بحيث تعكس خصوصية المعيار العراقي لنظام BIM.Due to the importance of the Building Information Modeling System (BIM) in the field of architectural design and construction, many countries have published standards and guidelines to organize engineering practice and to overcome its difficulties. The paper investigated the similarities and differences in the methods of managing information in BIM standards of the UK, USA, Australia and Singapore. The aim of the study was to establish a knowledge base for initializing the Iraqi BIM standards. To achieve this aim, the paper put forward a theoretical framework for processing information in the BIM system. The framework identified the methods at two levels. The first level is concerned with the design information, including the techniques of structuring design data, the techniques of storing the database, the techniques of coordinating and classifying building information and the techniques of representing information. The second level, on the other hand, is concerned with the digital techniques supporting the information management in BIM. It includes the techniques of digital collecting and storing information, the techniques of managing and exchanging information, the techniques of digital security, and finally the techniques of integration and interoperability in the digital representation of information. The techniques of utilizing information in BIM were investigated in the descriptions of the standards and guidelines of the four countries to determine their similarities and differences.
The comparative analysis findings revealed similarities in the techniques of digital storing, collecting and organizing information, in addition to the techniques of digital security and integration and interoperability of information. In this case, the shared techniques can be adopted in the Iraqi standards. The differences can be found in the techniques of structuring the design data, storing the database in the national library, and coordinating, classifying and representing the design information. They reflect the specificity of each country in the implementation of BIM. Therefore, these techniques Requires special preparation for the Iraqi standards of BIM
Scenarios of Building Information Modelling-Based Design Education in Architecture Schools
Due to the rapid development of computer technologies and trends in digital design, including building information modeling (BIM) and its diffusion into architectural design practice, it was necessary to introduce BIM into architectural curricula in order to prepare students for practice. This article therefore aims to identify scenarios for teaching BIM to architecture students worldwide. To achieve this objective, a thematic analysis of BIM teaching experiences in several selected academic institutions was conducted. The data studied included published articles and official university websites dealing with BIM teaching. A theoretical framework for BIM education was determined, comprising two aspects: pedagogical methods for BIM education and specifications for BIM courses in architecture programs. The document identified several scenarios for teaching BIM in multidisciplinary or architecture-specific courses. BIM teaching can be offered as part of a single course integrated with other courses, or as a separate course. It may be taught as part of related or unrelated courses. Related courses can be organized in parallel with an academic semester, or over several semesters. In addition, there are different types of input to project-based BIM teaching, such as a new design project, the results of a previous design course or an actual project. These scenarios can serve as a reference for universities wishing to integrate BIM into their programs

The generation and evaluation of more design solutions lead to more informed design decisions and the selection of the appropriate solution.
The research adopted the digital algorithmic approach to generating architectural plans and investigates the possibility of using the visual programming applied in Grasshopper, the (plug-in) of Rhinoceros software. Its aim was to create and implement an algorithm prepared by researchers, which depends on a specific data in producing new designs for typical buildings plans, such as schools, without the use of ready software in the generation process.
The research sought to obtain a number of alternative plans according to the user inputs. It hypothesized that the variation in the design inputs contributes effectively to the plurality of the generated design options.
