Numerical Study On Enhancing The Geotechnical Behavior Of Strip Footings On Oil-Contaminated Sand Using Stone Columns, Ahmad Nasr, Waseim Azzam, Mohamed Ahmed Mahmoud Abdelrehem

Journal of Engineering Research

Ground improvement techniques are frequently employed in construction sites characterized by weak soil conditions that may result in suboptimal performance. The use of ordinary and encased stone columns aims to enhance endurance, shear strength, and soil hardness, thereby mitigating settlement issues and expediting the consolidation of contaminated sand soils. In this research, a comprehensive investigation involving 74 cases was conducted to assess the behavior of both ordinary stone columns and encased stone columns under strip footing in contaminated sand subgrade. The objective was to discern the impact and characteristics of encapsulation in comparison to encapsulated stone columns, employing a Finite …

A Parallel Methodology For Early Fake News Detection Based On Hybrid Features On Social Media, Asmaa Mohemed Elsaieed Dr

Journal of Engineering Research

The increased use of social media platforms has made it easier to publish and distribute news items, but it has also opened up new opportunities for distributing fake news. Fake news is information that has been written with the goal of misleading or deceiving readers. As a result, there is a need for efficient false news identification tools where the information can be gathered from the text of posts or from publicly available social data (such as user information or feedback on articles or the social network). The detection of fake news in its early stages is a major challenge. …

Enhancing Radiation Performance Of A 0.18 Μm Cmos 60 Ghz On-Chip Double-Slot Vivaldi Antenna, Elsayed Ibrahim Elsaidy Mr., Amr H. Hussein Prof.Dr., Mustafa M. Abd Elnaby Prof. Dr.

Journal of Engineering Research

This paper presents the design of a 60-GHz double-slot Vivaldi antenna (DSVA) using standard 0.18 µm CMOS technology. The antenna's two slots are uniformly excited in both amplitude and phase by a coplanar waveguide (CPW) power divider. A double-Y balun feeding structure is also used to transition from the CPW to the coplanar slot line (CPS). Two techniques are investigated to enhance the antenna's radiation characteristics. The first technique involves incorporating equal corrugations along the edges of the flare aperture, resulting in a significant gain enhancement of 0.9 dBi and an improvement in radiation efficiency by 7%. The second technique …

Use Of Building Information Modeling (Bim) In The Management Of Construction Sector In Egypt, Asmaa Said Khalifa, Eman Attia, Hesham Awad

Journal of Engineering Research

Purpose – The application of Building Information Modelling (BIM) technology in Egypt is hindered by inadequacies or insufficient experience, as only a handful of companies and institutions are able to create three-dimensional models using this technology. Additionally, the majority of architectural education curricula do not fully incorporate BIM. The majority of Egyptian graduates in the fields of architecture, construction, and engineering lack the necessary knowledge or expertise to use BIM technology because universities in Egypt primarily focus on teaching CAD technology rather than BIM technology. This may be because BIM technology is still relatively new or because there aren't many …
