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, […]

Need-seeking: Creating, discovering or recovering needs?
Need-seeker approach, which orients new product development towards the satisfaction of future needs, has been recognized as one of the most efficient innovation strategies to date. But finding future needs to address remains a challenge for companies, entrepreneurs and practitioners, as they lack a methodological framework to structure their approach. In this chapter, we first […]

Multi-period optimal schedule of a multi-product pipeline: A case study in Algeria
The oil supply chain plays a vital role for both economic and social sectors in Algeria. Pipeline is the main oil transportation mode from production sites to distribution centers. However, finding the optimal schedule for a multi-product pipeline is among the most difficult optimization problems. In this article, we propose an operational schedule for a […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]
