Modern Fire Safety Protocols in the Archeological Contexts: A New Tool for Studying the Health and Behavioral Effects of Fire Use in Semi‐Closed Spaces

Archaeometry, EarlyView.
ABSTRACT This study evaluates the application of computational fluid dynamics (CFD) simulations, integrated with controlled fire experiments, to investigate combustion processes in semi‐closed spaces. The framework enables systematic modeling of smoke dispersal, particulate transport, and hearth performance under variable morphologies and ventilation ...

Experimental evaluation of the performance and power output enhancement of a divergent solar chimney power plant by increasing the chimney height

Frontiers in Energy Research
Solar energy is an attractive renewable energy option for countries located in the tropical region. Harvesting this energy using simple yet innovative technologies such as solar chimney power plants (SCPP) will help the developing countries in meeting ...

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

Computer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Topology‐based Visual Analysis of Hydrothermal Plumes

Computer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

Deregulation, government failure, and tragedy: The Report of Phase 2 of the Grenfell Tower Inquiry

Economic Affairs, EarlyView.
Abstract The Inquiry into the fire at Grenfell Tower, London, in 2017 has exposed the failures that led to the tragedy in a commendably exhaustive manner. But the explanation of those failures is seriously inadequate. First, they are attributed to deregulation, when the Inquiry itself details the ways in which the cladding of the building was subject ...

A Novel Method of Cooperating with Natural Ventilation and Heat Pump to Control the Thermal Noise of Super High-rise Elevator Shaft

Zhileng xuebao, 2021
The chimney effect in a super high-rise elevator shaft is significant in winter, which may cause difficulty in opening and closing the elevator doors and can produce obvious aerodynamic noise.

Bond strength enhancement for additively manufactured zirconia: Micro‐retentive design approach

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of digitally designed micro‐retention features on the bond strength of additively manufactured (AM) zirconia copings. Materials and Methods Sixty titanium base abutments (NobelParallel, NobelBiocare), pretreated with 50 µm alumina particles were divided into four groups (n = 15 per group); one group with ...

Performance study of a solar chimney air heater

Case Studies in Thermal Engineering, 2019
The thermal efficiency of conventional solar air heaters could be significantly improved by making some design configurations. In this study, a solar chimney air heater was employed and the effect of glazing, fins and convection (natural/forced) on the ...
