This paper presents a mobile Lidar system for efficiently and accurately capturing the 3D shape of the Bas-reliefs in Angkor Wat. The sensor system consists of two main components: 1) a panoramic camera and 2) a 2D 360-degree laser line scanner, which moves slowly on the rails parallel to the reliefs. In this paper, we first propose a new but simple method to accurately calibrate the panoramic ...
Heat exchangers are widely used in power engineering and industrial applications, many techniques such as coiled tube, surface tension devices, rough surfaces, extended surfaces have been investigated to enhancethermal performance and to minimize the cost and size of the heat exchanger equipment. One of the most important techniques is tube insert. In general,tube inserts can be classified into...
Abstract We consider the problem of determining, within an elastic isotropic nanoplate in bending, possible presence inclusion made different material. Under suitable a priori assumptions on unknown inclusion, we provide quantitative upper and lower estimates for area defect terms works exerted by boundary data when is present it absent.
Bi₂Se₃ nanocrystals with various morphologies, including nanotower, nanoplate, nanoflake, nanobeam and nanowire, have been synthesized. Well-distinguished Shubnikov-de Haas (SdH) oscillations were observed in Bi₂Se₃ nanoplates and nanobeams. Careful analysis of the SdH oscillations suggests the existence of Berry's phase π, which confirms the quantum transport of the surface Dirac fermions in b...
In this paper, we successfully grow GaAs/GaSb core-shell heterostructure nanowires (NWs) by molecular beam epitaxy (MBE). The as-grown GaSb shell layer forms a wurtzite structure instead of the zinc blende structure that has been commonly reported. Meanwhile, a bulgy GaSb nanoplate also appears on top of GaAs/GaSb core-shell NWs and possesses a pure zinc blende phase. The growth mode for core-s...
generally, fatigue failure in an element happens at the notch on a surface where the stress level rises because of the stress concentration effect. the present paper investigates the effect of a notch on the fatigue life of the hsla100 (high strength low alloy) steel which is widely applicable in the marine industry. tensile test was conducted on specimens and mechanical properties were obtain...
Correction for ‘Spherical Co 3 S 4 grown directly on Ni–Fe sulfides as a porous nanoplate array FeNi foam: highly efficient and durable bifunctional catalyst overall water splitting’ by Jun Shen et al. , J. Mater. Chem. A 2022, 10 5442–5451, DOI: 10.1039/d1ta07504g.
At low pressure, ethylene gas consists of single translating and rotating molecules and behaves as an ideal gas. With decrease of free volume by compression, various rotating supramolecular particles are formed, which require less space for the movement: molecular pairs, bimolecules and oligomolecules. The appearance of a new kind of particles is manifested as a phase transition of the second o...
With the development of highly-deviated well cementing techniques, rotating casing cementing technology has got more and more attention. The rotating casing technique can improve the displacement efficiency of cement paste, and then enhance the quality of well cementation. In the stuck section, the rotating casing can redress the well to make the casing run sequentially. The casing endures shea...
