Neighbourhood Planning: Reminiscence Towards Liveable Communities, Bolanle Wahab, Waheed Kadiri, Ayobami Popoola, Bamiji Adeleye, Robert A. Dwamena

CSID Journal of Infrastructure Development

Urbanisation remains a topical discussion across the globe. According to the United Nations (2022), 68% of the world's population will be absorbed in urban areas by 2050. The envisaged rapid urbanisation in cities by 2050 is believed to be accompanied by various planning problems, which include accelerated climate change, urban slums, urban sprawl, poor sanitation, inadequate infrastructure, overcrowding, housing deficiency and transportation issues. To mitigate these planning problems, the role of effective urban planning cannot be overemphasised. Urban planning provides a pathway for overcoming the various challenges posed by urbanisation both in the present and in the future.

Deep Learning Based Classification Of Focal Liver Lesions With 3 And 4 Phase Contrast-Enhanced Ct Protocols, Ahmed El-Emam, Hossam El-Din Moustafa, Mohamed Moawad, Mohamed Aouf

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 …

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 …

Localized Surface Plasmon Resonance Of Palladium Parallelepiped Nanoparticles, Salem Marhaba, Nourhan El Kawni

BAU Journal - Science and Technology

Localized surface plasmon resonance (LSPR) of palladium parallelepiped nanoparticle have been investigated using Finite Element Method (FEM) in the frame of COMSOL Multiphysics Software. Spectral characteristics (magnitude, peak position and width) of LSPR of a single Pd nanoparticle having the shape of a parallelepiped are investigated in two different cases. The first case studied the size effect on LSPR by fixing the height with varying both length and width. However, the second case studied the shape effect on the LSPR by rounding the corners of the parallelepiped for different radii while fixing its dimensions. The extinction cross-section spectra of these …

The Influence Of Environmental Tax And Technology On Different Air Pollution Emissions In Oecd Countries, Malak Ali Assaf

BAU Journal - Creative Sustainable Development

Although countries continuously employ taxation and technological measures to control air pollution in the Organization for Economic Co-operation and Development, the results of these practices should be evaluated to determine whether they reach their intended outcomes. This study used panel autoregressive distributed lag model to establish how environmental taxes and technology affects the emission of air pollutants (nitrogen oxides, Carbon dioxide, and particulate matter 2.5). Using secondary data present in the OECD Database and The World Bank, EViews panel was derived to create 3 model in which each of the three variables would be sufficiently explained by environmental tax, abatement …
