Abstract: Construction projects continue to record cost and time outcomes that fall short of their baseline commitments, and a recurring explanation across four decades of research locates the problem in weak feedback between site conditions and managerial decisions rather than in technical uncertainty alone. Business intelligence (BI) platforms, which convert dispersed operational records into interactive visual reports, have been advanced as a route to closing this feedback loop, yet the supporting evidence remains scattered across several research communities that seldom cite one another. This paper reviews forty-five peer-reviewed studies published between 1992 and 2024....

Abstract: Background: Unethical practice in construction erodes safety, quality and public value, and its effects are most acute in fragile, low-governance economies. This study assesses the self-reported ethical conduct of civil engineers in construction projects in Khartoum State, Sudan, across seven ethical dimensions derived from international codes of practice and the ethical decision-making literature
Materials and Methods: A cross-sectional survey using a 36-item, five-point Likert questionnaire was administered electronically....

Abstract: The local surface shear stress around small triangular protuberances in supersonic flow has been measured, quantitatively and qualitatively, using calibrated Liquid Crystals. Measurements were taken within a turbulent boundary layer on the floor of a Mach 3.8 wind tunnel using high speed image capture of 1000 fps. Results are presented of the distribution of the shear stress values upstream and downstream of the protuberance as well as the streamwise distribution at the side of the protuberance. It is shown that shear stress patterns for protuberances at an inclined....

Abstract: A curved flat plate solar collector represents a novel adjustment of the traditional flat plate collector aimed at enhancing solar energy capture by expanding the active surface area and minimizing reflection losses. This research examines the thermal performance of a newly developed curved flat plate solar collector in different environmental conditions. Critical performance metrics like outlet water temperature, effective heat gain, collector efficiency, and....

Abstract: Background: Civil infrastructure faces pressures, such as mechanical stress, environmental changes and climate-related challenges. Civil infrastructure maintenance decisions are often made without using data from design, construction, inspection or operation.
Materials and Methods: We create a lifecycle view that brings together twins, embedded sensing, artificial intelligence, edge computing and predictive maintenance for climate-resilient civil infrastructure. Then seeing these tools as separate we....

Abstract: Decarbonization is one of the most discussed topics today when it comes to environment, energy, and sustainable development. We need to know the effect of global warming and net-zero initiative. As we know that, fossil fuels are the major source of air pollution, and that is responsible for around five million premature deaths every year around the world. For both climate change and human health, we need to transition away from fossil fuels towards low carbon or clean energy sources. But question is, how quickly are we making progress on this? It....
