Effect Of Dual-Fuelled Cng And Gasoline On Spark Ignition Engine Performance And Emissions Behaviors At Different Loads, Medhat Elkelawy Prof. Dr, Eng., M.M. Bassuoni Prof. Dr., Hagar Alm-Eldin Bastawissi, Saied I. Haiba Eng.

Journal of Engineering Research

Engine emissions are one of numerous factors that have detrimentally affected the environment, such as global warming, which is the result of growing exhaust gases, practically carbon dioxide (CO2). These emissions have substantially influenced researchers to develop strategic initiatives to minimize the carbon contents of fuels. The purpose of this research is to investigate the characteristics of internal combustion (SI) engines fueled by gasoline and compressed natural gas (CNG) blends. The experiments are performed using a HONDA 4-stroke, single-cylinder, and air-cooled SI engine. Five CNG concentrations are evaluated, the concentrations range from 0.5 to 2.5 L/min with a 0.5 L/min …

Journal of Engineering Research

Petroleum fuel prices fluctuate in response to global political and economic issues. Government regulations should be followed when it comes to engine emissions, as these dangerous pollutants have a negative impact on the environment. One such effect is global warming, which raises global temperatures. The purpose of this study is to develop the additives for use as a fuel mix with diesel fuel, which will be used to feed the diesel engine of a single cylinder, four strokes. The engine will be tested experimentally with varying loads at fixed speed of 1500 rpm, using blends of [(5% PRETSONE additive + …

Design And Implementation Of A Low-Cost Educa-Tional Robot For Engineering Curriculums, Diana Refaat Henry Jacob, Ashraf Mohamed Hafez, Mohamed Tarek Elawa

Journal of Engineering Research

The role of educational robots is becoming increasingly important. Many commercial educational robots differ in their abilities and price. In general, the cost of these robots presents the main cause of their limited use in the teaching process, especially in countries with limited financial resources. This work attempts to solve this problem by designing and implementing an educational robot with a limited budget. The robot was initially intended to serve higher education students' needs, especially in engineering curriculums but can be extended to other application areas. This work presents robot hardware functional blocks, mechanical struc-ture design, and 3D printing implementation. …

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. …

A Greening The Diesel: Vegetable Oil Biodiesel Blends For Cleaner Emissions And Improved Direct Injection Diesel Engine Performance, Medhat Elkelawy Prof. Dr, Eng., Hagar Alm-Eldin Bastawissi, E. A. El Shenawy Prof. Dr., Mustafa Mohamed Ouda

Journal of Engineering Research

In this study, we conducted comprehensive experiments to assess and compare the performance of pure diesel fuel against biodiesel produced from corn oil in various blend ratios (15/85, 30/70, 45/55, and 60/40) in a conventional four-stroke, direct-injection diesel engine, fuel is injected directly into the combustion chamber at the end of the compression stroke, allowing for efficient combustion and power generation over four distinct phases: intake, compression, power, and exhaust. Each fuel blend was tested at an engine speed of 16,000 rpm across different load conditions (low, medium, and high). Key performance metrics, including volumetric fuel consumption, exhaust smoke, and …

Geometric Morphological Analysis Of The Edfu Temple, Yara M. Soliman, Ashraf H. Ibrahim, Ahmed M. Awad

Journal of Art, Design and Music

The paper discusses the influence of nature on the design principles utilized by ancient Egyptian civilization, emphasizing how philosophers and artists learned from natural forms. It introduces the concept of Morphology, which examines the structures and forms of living and inanimate objects, categorized into eight types: Geometric, Chaotic, Plant, Animal, Human, Motor, Ecological, and Symbolic. The research focuses on applying the Geometric Morphological system to Edfu Temple, highlighting the need for contemporary designers to consider both form and content, rather than merely aesthetic shapes. The study aims to create an analytical framework using geometric determinants—unity, balance, scale, rhythm, proportion, abstraction, …

Balancing Sustainability With Preservation In Historic Italian Architecture, Maya A. Bruno

CISLA Senior Integrative Projects

This research examines the intersection of historic preservation and sustainability in Italian architecture, analyzing how architects and contractors adapt historic structures to modern energy efficiency standards while maintaining cultural integrity. Using three Italian case studies—Ex-STA.VE.CO in Bologna, Sant’Apollinare in Perugia, and Castelvecchio in Verona—the study explores common challenges in regulatory compliance, material constraints, energy efficiency, seismic resilience, and adaptive reuse. Each case illustrates how sustainability measures interact with Italy’s stringent conservation laws and how historic buildings, inherently designed for climate adaptability, can be innovatively retrofitted. The findings provide insights into reconciling preservation principles with sustainable interventions, offering policy recommendations for …

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.

Polarimetry Based Radar Estimation Of Extreme Rainfall: Case Studies, Bong Chul Seo, Witold F. Krajewski, James A. Smith

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The study evaluated radar-derived polarimetric rainfall estimates for extreme rain events that occurred in the Kansas City Metropolitan area in the United States. To derive quantitative precipitation estimates (QPE), we implemented two polarimetric algorithms based on specific attenuation (A) and specific differential phase (KDP), along with the reflectivity (Z) based one using data from two radars in the study area. The analysis to assess radar-rainfall estimates (R) utilizes ground observations from a dense network of about 170 rain gauges. Based on our analysis results, the two polarimetric estimates from R(A) and R(KDP) outperform the conventional estimation R(Z). R(A) appeared to …

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 …
