The research provides and validates a new mechanism that could be used in the design process of shared office spaces, by integrating the tool of Virtual Reality (VR) and User Experience Design (UXD). The proposed mechanism consists of three phases. The first phase (the experiment articulation) illustrates the correlation between the satisfaction factors of users and the physical setting of shared office spaces. In the second phase (the experiment tool preparation), the research articulates the programing scripts which are necessary for the users’ interaction in the experiment using the VR tool, called User Interaction Tool (UIT), where these scripts are: Mouvement Script; Rotation Script; Stretch Script; and Material Script. The third phase (the experiment implementation and tool evaluation) consists of three steps; the first one is an oriented questionnaire for determining users’ needs in shared office space while establishing relative weight for every aspect, and the second step is the experiment implementation for an existing office space to explore the suggested scenarios using the proposed tool, and the third step is crucial for comparing between the existing design model and the deduced one from the proposed mechanism to evaluate the validity of the proposed tool. After testing the tool, the research finds that users’ satisfaction before the experiment is about 43.352 %, while it has been raised to 86.5825 % after using the proposed mechanism. Hence, the users’ satisfaction is almost doubled after using the virtual reality tool in the design process of office space design.","PeriodicalId":440630,"journal":{"name":"MSA Engineering Journal","volume":"33 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130003082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The novelty of the present method that it is converted Linear Boundary Value Problems to initial Value Problems using accurate numerical methods and then uses Laplace transforms method to find approximate to the exact solution. Approximate to Exact Method (AEM) is an algorithm, with a very strong accuracy that approaches the exact solution because it is a mixture of numerical methods of very high accuracy with a closed-form method.

The first study analyzed the residential examples. In this paper the non-residential secular buildings were analyzed, while the religious buildings will be the topic of a third forthcoming study. The secular non-residential buildings found were a very small number (twelve only) and have been categorized into commercial, public and educational. No one dominant or clear Islamic style has been noted, and out of seven contemporary styles of architecture we know of only three were noted in our case studies: eclectic (two), neo-Islamic (three) and the dominating Modern Simplified Islamic (seven), yet we find great variations in each style and no consensus on the vocabulary used or details. The study suggests four reasons for using the Islamic styles in those types: expected patron/owners’ image, design intent, need for differentiation, nostalgia and creating a marketable image. It is also noted that in all of the examples recorded with one exception, the Islamic styles or principles were limited to the facades but were not reflected in the layout. Only one example echoed an Islamic urban pattern for its layout in addition to its façade detailing. The situation can be described as chaotic fraught with eclectic styles, with borrowings and re-interpretations of details from different eras and countries, with no clear dominant “style” emerging or even beginning to evolve. No specific style or detail dominated. This eclecticism and chaos is most probably a reflection of the lack of familiarity of the historical styles by the designers, with exceptions of some successful interpretations. Once again, our analysis shows that the lack of identity","PeriodicalId":440630,"journal":{"name":"MSA Engineering Journal","volume":"26 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120859213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research also discussed the different approaches to explain the visual formation or the image of the city, in order to derive the criteria for measuring the performance of the aesthetics of the urban formation of the city centre, which was based on the eleven Edinburgh criteria. The research added a new criterion representing modern technologies and smart materials to become twelve criteria. The research was able to analyse the main criteria into a set of sub-criteria with 76 criteria, then extract their characteristics and performance indicators (KPIs) for each criterion with a total of 291 indicators. The relative weights of these indicators were also calculated in a mathematical way based on the frequency of the indicator through the analysis of (9) experiments (including 5 global & 4 regional). These indicators were established to produce the proposed model for measuring the performance of the aesthetics of urban formation, which is the main objective of the research, and it was tested by applying it to the Egyptian experience on city centres of different generations represented in the 6th. of October, Al-Rehab, the New Administrative Capital and Madinaty.

This makes SM prone to channel irregularities like multipath Raleigh fading. Hence, employing and optimizing a transmit precoder (TPC) that matches the channel can enhance the SM bit error rate performance by increasing the Euclidean distance (ED) among all possible received vectors. However, it is common that optimization algorithms endure high complexity. Focusing on MPSK constellation, and by reducing the number of Euclidean Distance constraints, we cut the complexity by nearly a factor of M. This is a significant reduction for high order constellations with a large value of M. This concept is shown to benefit any TPC optimization algorithm for SM and its variants. To further shrink the complexity, we introduce an optimization algorithm that minimizes the sum of the exponentials of negative EDs. The paper shows that the complexity can be reduced significantly without loss in performance.","PeriodicalId":440630,"journal":{"name":"MSA Engineering Journal","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130637143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern natural sciences have been created to acquire technological mastery over natural processes, resulting in a never-ending stream of new items and technology being introduced into current society, enhancing living comfort and raising overall human well-being. As a result, this technological advancement has unintentionally resulted in increased fossil fuel use, population expansion, urbanization, and deforestation, all of that put further strain on future resources owing to pollution, resource depletion, and biodiversity loss. The study aims to analyse discussions over digital architecture and new industrialization as well as the impact of biotechnology on architecture, interior design, and more especially, the usage of living or semi-living materials in our built environment. Furthermore, as a material and technical innovator, a strong understanding of the disciplines of computational data generation, 3D printing, and digital manufacturing is critical. In addition, bio-augmented design investigates our current interaction with nature. It is the scientific study of life and living entities, ranging from simple organisms to the most sophisticated. The study demonstrates bio-fabrication, which involves designing with living beings where biosynthesis is replacing traditional manufacturing, plants which manufacture items, microbes which develop new materials, and energy-efficient bio designs. Furthermore, these new composite materials provide a vision into the near future when synthetic biology may be used to assist us in designing and building the built environment with higher performance and lower environmental impact than traditional architectural, as well as interior design approaches. The research highlights the shift from nature-inspired design to nature-integrated design. Many recent biological trends identify biofuturistic design as a paradigm shift in interior design, creating a distinct interface for tectonic and ecological materials between nature and design, as well as an orientation towards healthier structures.
