Assessment of the effect of fiber percentage in glass fiber reinforced slag-based geopolymer
Fibers can increase the ductility of geopolymer materials, acting as reinforcements to improve mechanical properties. These improvements depend on fiber content and quantity. This study evaluates the impacts of different percentages of glass fiber on a GBFS (ground blast furnace slag) geopolymer matrix. The glass fibers were used on the critical length of 20 mm, […]

A security policy hardening framework for Socio-Cyber-Physical Systems
Modern systems are heterogeneous inter-operating subsystems of different aspects that can be physical, technical, cybernetics, and even social like agent operators in smart grids or smart transportations. With the social dimension, we name these systems by Socio-Cyber-Physical Systems (SCPS). However, ensuring safety, correctness, and security against attacks that can be either technical or socio-technical based […]

Recent advances in thermophysical properties enhancement of phase change materials for thermal energy storage
Phase change materials (PCM) are promising technology to store thermal energy at a constant temperature. A large amount of energy can be stored or released in latent heat form during the transition of material from one phase to another. Despite the great benefits, most PCMs have their own limitations i.e., low phase change enthalpy, poor […]

BIM-Based Digital Twin and XR Devices to Improve Maintenance Procedures in Smart Buildings: A Literature Review
In recent years, the use of digital twins (DT) to improve maintenance procedures has increased in various industrial sectors (e.g., manufacturing, energy industry, aerospace) but is more limited in the construction industry. However, the operation and maintenance (O&M) phase of a building’s life cycle is the most expensive. Smart buildings already use BIM (Building Information […]

Evaluating turbulence models to predict the particle deposition in curved ducts
This study aims to evaluate the capability of eddy-viscosity and Reynolds stress models to describe the particle deposition efficiency of gas-solid turbulent flow in a square-sectioned curved duct using the Eulerian-Lagrangian approach. The air flows with a Reynolds number of 40,000 through a 90-deg bend of 0.08 m hydraulic diameter and a curvature ratio of […]

Explicit analysis of large transformation of a Timoshenko beam: post-buckling solution, bifurcation, and catastrophes
This paper exposes full analytical solutions of a plane, quasi-static but large transformation of a Timoshenko beam. The problem is first re-formulated in the form of a Cauchy initial value problem where load (force and moment) is prescribed at one end and kinematics (translation, rotation) at the other one. With such formalism, solutions are explicit […]

Financial literacy and individual success: Lebanese framework modeling
This paper sheds light on the role the financial literacy features may play amid other determinant factors of individual success. A survey is conducted on a random sample of households’ members, based on the individual perception as an assessment criteria of financial literacy status and career success. A non-parametric method, ctree, and a semi-parametric method, […]

Guaranteeing Information Integrity through Blockchains for Smart Cities
Given the threats that the smart city faces especially tampering the integrity of information, it has become necessary to integrate more robust and decentralized technologies that ensure transparency and sustainability of the system. Blockchain is a technology initially directed to limit the manipulation in financial transactions. One of the most popular currencies adopting this technology […]

Coverage Maximization in WSN Deployment Using Particle Swarm Optimization with Voronoi Diagram
Coverage area maximization is a crucial issue that must be considered in Wireless sensor network (WSN) deployment as long as it impacts the sensor network efficiency. In this paper, a novel approach based on particle swarm optimization (PSO) and voronoi diagram is developed to solve WSN deployment problem. The objective of the proposed solution is […]

COVID-DETECT: A Deep Learning Based Approach to Accelerate COVID-19 Detection
After two years of COVID-19 first infection and its speedy propagation, death and infection cases are till exponentially increasing. Unfortunately, during this a non-fully controlled situation, we noticed that the existing solutions for COVID-19 detection based on chest X-ray were not reliable enough in relation to the number of infected patients and the severity of […]

A Generation and Recovery Framework for Silicon PUFs based Cryptographic Key
Integrated Circuits (ICs) and electronic devices became the main part of human daily life (mobile, home, car, etc). However, for the safety of the transported information to and from these devices, some speci cs security measures should be taken. In general, ICs are a source of high randomness due to the manufacturing variation process which […]
