Abstract: From the use of a pinhole camera placed under a water tank, which was proposed almost 100 years ago, to the application of modern digital cameras mounted with sophisticated fisheye lenses, acquisition methods for capturing ...

Abstract: A method of compacting dolomite into water as a part of Al‐Qadisiya Dam core construction is discussed in light of laboratory and field tests. Main characteristics of dolomitic soils are compared with the requirements for ...

Abstract: There has been a long-standing debate in the literature as to why and how leadership is similar to, or different from, management. Although several scholars have contributed to the debate, there seems to be an absence of ...

Abstract: A method for optimizing the geometrical layout for a façade-mounted solar photovoltaic array is presented. Unlike conventional studies, this work takes into account the finite height of the façade, which is more realistic. ...

Abstract: In this paper, the energy collection performance of north/south- and east–west-facing collector pairs, installed at optimized fixed and seasonally adjusted tilt angles, considering both portrait and landscape alignments, ...

Abstract: This paper presents a method for evaluating the intercept factor (γ) of a beam-down parabolic trough collector (BDPTC), accounting for collector design, solar cone, and shading on the aperture due to secondary reflectors. ...
