Topology I INTRODUCTION Topology, branch of mathematics that explores certain properties of geometrical figures.unknown
of the cube have equal dimension. take a cheese cube box and cut it out along the edges to make the net for a cube. cone a cone is a solid object that has a circular base and has a single vertex. it is a geometrical shape that tapers smoothly from the circular flat base to a ...
Angles are geometric figures formed by two rays, meeting at a common endpoint. Angles are measured in degrees. The symbol of angle is ∠. It can be measured using a protractor, easily.
Ground deformation can cause serious environmental issues such as infrastructure damage, ground compaction, and reducing the ground capacity to store water. Mashhad, as one of the largest and most populated cities in the Middle East, has been suffering f
Final citation details, e.g., volume and/or issue number, publication year and page numbers, still need to be added and the text might change before final publication. Although corrected proofs do not have all bibliographic details available yet, they can already be cited using the year of ...
Recently, extensive R&D has been conducted, both by industry and academia, to significantly raise the conversion efficiency of commercial photovoltaic (PV) modules. The installation of PV systems aimed at optimizing solar energy yield is primarily di
Browse Figures Versions Notes Abstract Tensile strength and fracture toughness are two essential material parameters for the study of concrete fracture. The experimental procedures to measure these two fracture parameters might be complicated due to their dependence on the specimen size or test method....
Meanwhile, the buckling or flattening phenomenon relies on the geometrical feature (i.e., length and diameter) of the SWNT, and thus, the fracture behavior of different SWNTs varies from each other. Additionally, the elastic constant increases generally when the diameter of CNT increases, which...
of the sulfonated molecule. The geometrical thresholds, used to establish the H-bond formation, were a donor-acceptor distance of 2.1 Å and a cutoff angle of 120° [26]. Instead, the hydration number, NH, is defined as the number of water molecules required for achieving the asymptotic ...
Browse Figures Versions Notes Abstract The mechanical properties in laser-based powder bed fusion (PBF-LB/M) manufactured parts are anisotropic in nature due to the layer-wise build-up but also change due to different solidification conditions in dependence on the process strategy and the geometry...
