Using Multi-Criteria Decision Analysis (MCDA), different adaptive reuse scenarios are evaluated in HBIM Environment to ensure that interventions respect the building's authenticity, integrity, and significance while meeting sustainable operational needs. The case study focuses on Bayt Yakan, a 17th-century heritage building in Cairo, where three adaptive reuse scenarios—continued use as a library, conversion into a hotel …

Experimental And Numerical Investigation For Optimum Design Of Hydraulic Steel Gates, Basma Hassan Mohamed Eng, Ahmed Mohamed Anwer Dr, Hanan Eltobgy Prof., Gamal Helmy El-Saeed Prof

Journal of Engineering Research

Conventionally, steel gates are widely used in hydraulic structures for their superior mechanical properties in sustaining hydrostatic pressure. Maintenance and operational costs should be considered while studying the feasibility of these gates. In the current research, three prototype steel gates with different configurations were prepared and examined experimentally. The three gates have the same surface dimensions of (width x height) equal to (1.0 x 1.25 m). The first steel gate represents a typical traditional gate made of skin plate and stiffened laterally using standard steel channels and will be kept for comparison. The second gate represents a standard thicker plate …

Performance And Emissions Characteristics Of Multi-Cylinder Direct Injection Diesel Engine Fuelled With Diesel/Biodiesel And Toluene Additives, Hagar Alm-Eldin Bastawissi, Medhat Elkelawy Prof. Dr. Eng., Mohammed Osama Elsamadony Dr. Eng., Moustafa Ghazaly Eng.

Journal of Engineering Research

This study explores the impact of using a diesel, biodiesel, and toluene additive fuel blend in a multi-cylinder direct injection diesel engine, focusing on both performance and emissions characteristics. Biodiesel, made from renewable sources like vegetable oils, is often added to diesel to reduce reliance on fossil fuels and improve combustion due to its higher oxygen content. In this work, a 45% biodiesel blend (B45) led to significant reductions in particulate matter (PM) emissions by up to 40% compared to conventional diesel. Additionally, carbon monoxide (CO) and hydrocarbon (HC) emissions decreased by up to 30% and 25%, respectively, due to …

The Design Studio Dilemma The “Slicing Method”, Yasser Osman El Gammal Associate Professor Dr.

Journal of Engineering Research

The design studio presents a multifaceted challenge due to the absence of a direct teaching approach, relying heavily on the teacher's expertise, design acumen, and pace. Furthermore, much of the existing literature on design studio methods tends to be philosophical or opinion-based, lacking practical solutions for ongoing challenges in this domain. While it's easy for scholars to theorize, offering comprehensive procedures to address design studio issues proves considerably more difficult. There's no unanimous agreement on the topic; most design studio models are based on individual opinions as scholars and practitioners view the topic from different angles, developing their own perspectives. …

The Influence Of Sustainable Lighting On Modern Structures And The Methods Used To Bring Artistic Elements To The Forefront Of Sustainable Lighting Design, Abigail Abrams

Mahurin Honors College Capstone Experience/Thesis Projects

Sustainability in architecture is a broad subject in the discipline that has been gaining popularity across the globe for the past three decades. While sustainable technologies are heavily researched, more specific methods in which sustainability blends within a building are infrequently studied. In particular, the way sustainability is integrated into the lighting design of buildings is a topic receiving limited study from architects and researchers alike. This paper and project explore the methods modern architects use in establishing a design-centered lighting system throughout a building that reflects a new age of building materials, sustainable technology, and construction practices.

Small-Scale Green Infrastructure In Urban Networks - Trinity Presbyterian Church As A Pilot Project, Selvana Getsy -

Landscape Architecture Masters & Design Theses - Archive

Rapid urbanization and increasing impervious cover in cities like those within the Dallas-Fort Worth metroplex have intensified flooding, heat, erosion, and declining ecological quality. Although large-scale green infrastructure (GI) interventions are widely recognized as solutions to these issues, small-scale institutional landscapes remain a neglected yet powerful component of urban GI networks. This study functions as a pilot/demonstration project to evaluate the potential of small-scale GI interventions at Trinity Presbyterian Church, Plano, Texas. The goals are to reduce stormwater runoff, provide ecological and microclimatic improvements, increase community engagement, biodiversity enhancement, and environmental awareness in public institutional settings.

The study utilizes a …
