Towards a reliable smart city through formal verification and network analysis
With the immense increase of population density, many challenges facing organizations and governments. Thus, it has become mandatory to turn up our cities to be intelligent by introducing IoT and smart grids to build smart buildings, smart communication technologies, smart healthcare systems, smart transportation, etc. Smart cities guarantee the healthy living of indoor inhabitants by […]

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 […]

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 […]

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 […]

Urban Heat Island Causes, Consequences, and Mitigation Measures with Emphasis on Reflective and Permeable Pavements
Economic and social development of urban and rural areas continues in parallel with the increase of the human population, especially in developing countries, which leads to sustained expansion of impervious surface areas, particularly paved surfaces. The conversion of pervious surfaces to impervious surfaces significantly modifies local energy balance in urban areas and contributes to urban […]

Building Occupancy Behavior and Prediction Methods: A Critical Review and Challenging Locks
Energy use in buildings is increasing to provide optimal comfort for the occupants. People spend 90% of their lifetime in buildings. Therefore, indoor environment quality and comfort management have a crucial role in maintaining occupants’ health and productivity. Reducing energy consumption for optimal comfort management is important to minimize CO 2 emission and global warming […]

Toward BIM and LPS data integration for Lean site project management: A State-of-the-Art review and recommendations
Over recent years, the independent adoption of Lean Construction and Building Information Modeling (BIM) have shown improvements in construction industry efficiency. Because those approaches have overlapping concepts, it’s thought that their synergic adoption can bring much more benefits. Today, the implementation of the Lean-BIM interactions theoretical framework is still challenging many companies. This paper conducts […]

Augmented design with additive manufacturing. methodology: Tangible object-based method to enhance creativity in design for additive manufacturing
Additive manufacturing (AM) brings new design potential compared with traditional manufacturing. Nevertheless, traditional manufacturing knowledge remains embedded in the minds of designers and is a real cognitive barrier to design in AM. Design for Additive Manufacturing (DfAM) provides tools, techniques, and guidelines to optimize design with the specifics of AM. These methods are usable at […]

Comparative analysis of hydraulic refrigeration and mechanical vapour compression water cooling technologies in designing a technical system for oysters conservation
The phenomenon of summer mortality in Pacifi c oysters cultures also occurs in Brazilian crops, with predominance in the adult phase, generating signifi cant losses for local producers. In the search for a technological solution to mitigate its effects, the mechanical vapour compression and hydraulic refrigeration concepts are evaluated as two proposed cooling technologies. The […]
