Mansoura Engineering Journal
It had been noticed that 3-phase and 4-phase computed tomography protocols with contrast serve as standard examinations for diagnosing liver tumors. Additionally, many patients require periodic follow-up, which entails significant radiation exposure for them. Advancements in image processing facilitate automated liver lesion segmentation. However, the challenge remains in classifying these small lesions by doctors, especially when the liver has different types of lesions with very little intensity difference. Therefore, deep learning can be utilized for the classification of liver lesions. The present work introduces a CNN-based module for the classification of liver lesions. The module consists of four stages: data …

Mansoura Engineering Journal
The purpose of this research is to investigate the impact of hybrid micro and macro polypropylene fibers (PPFs) on the mechanical characteristics and microstructure of high performance concrete (HPC). Seven concrete mixes with different contents of hybrid polypropylene fibers were tested. The tests included the slump test, compressive and flexural strength, resistance to elevated temperatures, and concrete microstructure. Compared to the control mixture, introducing macro and micro polypropylene hybrid fibers to HPC mixes dramatically enhanced the flexural and compressive strength of concrete while lowering workability. HPC compressive and flexural strengths decrease as temperature rises, nevertheless, the strength loss rate was …

Neural Network-Based Fault Distance Estimation For Multi-Terminal Dc Microgrids, Mohamed Elmadawy, Abdelhady Ghanem, Sayed Abulanwar, Ahmed Shahin
Mansoura Engineering Journal
Fault distance estimation in DC microgrids is a critical issue due to the growing adoption of DC-based distribution systems. Current methods face limitations like sensitivity to system parameters and high-resistance fault detection, necessitating improved accuracy. This study proposes a neural network approach to accurately locate fault distances in multi-terminal DC microgrids. Three different structures based on backpropagation algorithms are developed and trained to estimate fault distances with high precision. These structures can handle various fault scenarios, including different fault resistances and the presence of noise. Two of the structures can predict fault distances from one side locally, achieving low error …

Mansoura Engineering Journal
Buildings are responsible for 39% of global energy-related carbon emissions; 11% come from materials and construction, and 28% come from operational emissions (the energy required to heat, cool, and power). Embodied carbon will contribute an increasing amount to the emissions from new buildings in the future as carbon emissions from building operations continue to decline. This study examined several construction methods and materials to evaluate alternatives for remodeling a residential villa. A villa in the Al-Qassim Region, Buraidah, served as a case study for this research. The methodology employed provided a meticulous appraisal of the building materials and techniques currently …

Influence Of Macro-Synthetic Fibers On The Flexural Behavior Of High Strength Concrete Beams Reinforced With Gfrp Bars, Maryam M. Koura, Ahmed M. Tahwia, Mohamed H. Matthana
Mansoura Engineering Journal
Rusting of steel reinforcement in marine environments causes the overall destruction of reinforced concrete constructions; steel rebars in concrete members have been replaced with fiber-reinforced polymer (FRP) bars in recent years. To enhance the shear behavior of glass (GFRP) bars reinforced concrete (RC), macro-synthetic polyolefin (PO) fiber was added. These materials have a low modulus of elasticity, a high tensile strength, and a linear stress-strain response to full failure. This study investigates the effect of macro synthetic structural fibers on the post-cracking and deformability properties of high strength concrete reinforced with FRP bars without transverse reinforcement. Eight full-scale RC beams …

The increasing number of motorized vehicles in Jakarta is causing environmental damage and can harm human health. In recent years, the Jakarta local government has the vision to focus on improving the human mobility network, including the pedestrian networks. As a heavily trafficked road, Jalan Kyai Tapa, West Jakarta, is used by many people. However, it may feel uncomfortable to walk there due to heat and sun exposure, which is compounded by extensive pavement coverage. The thermal condition of the pedestrian corridor is essential to create a comfortable walking experience. The objective of this study was to analyze the thermal …

Interacting Action Of Alkali-Silica Reaction And Chloride-Induced Steel Corrosion On The Reinforced Concrete Structures – A Critical Review, Williams Dunu
CSID Journal of Infrastructure Development
The degradation of reinforced concrete (RC) structures amidst the progression of corrosion within alkali-silica reaction (ASR)-affected structures is a complex phenomenon marked by diverse causal factors and repercussions. While the initiation phase of chloride-induced steel corrosion and ASR in RC structures has received extensive scrutiny, insufficient attention has been dedicated to comprehending the propagation phase (tp). Therefore, this study addresses this gap by centering its focus on the propagation phase, driven by the imperative need to formulate efficient and sustainable maintenance, repair, and management strategies for RC structures grappling with the concurrent impacts of degradation mechanisms such as ASR and …

CSID Journal of Infrastructure Development
This study investigates the state of outdoor green infrastructures (GI) in Aksum, Ethiopia, employing qualitative and quantitative approaches to address the disconnect between the expanding urban fabric and sustainable green space development. Sentinel satellite imagery and public perception surveys revealed a fragmented landscape of green spaces, including underdeveloped areas like heritage sites, cemeteries, churches, public spaces, stream fronts, and roadside spaces. Quantitative analysis using the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-Up Index (NDBI) indicated limited healthy vegetation and a built environment predominance. NDVI values ranged from +0.1 to +0.5, suggesting the presence of grass and shrubs, while …
