Transient Response and Strength Analysis of Perforating String
Shiyou jixie, 2017 For a better understanding of dynamic response and stress intensity safety of the perforating tubular string under detonation loads, a finite element model of perforating tubular string has been established by using ANSYS.

Development of the Optimum Design Software for CT Velocity String
Shiyou jixie, 2018 There is no coiled tubing velocity string optimization design software in China, and the calculation model of foreign related software is old fashioned with difficult operation, whose function does not meet the on-site demand. To address the issue, using

Advanced Materials, EarlyView.We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Regulation of the downside angular velocity of a drilling string with a P-I controller [PDF]
2018 European Control Conference (ECC), 2018 In this paper, we demonstrate that a simple Proportional Integral controller allow to regulate the angular velocity of a drill-string despite unknown friction torque and by only using measurement of angular velocity at the surface. Our model is an one dimensional damped wave equation subject to an unknown dynamics at one side while one control and ...

Single and twin string cavitation swirling flows in multi-hole mini-sac diesel injector and sprays
Journal of Fluid Science and Technology, 2023 A new design of fuel injector for diesel engines is expected to enhance fuel spray atomization at the end of the fuel injection for the reduction in particulate matter emission. It was pointed out that string cavitation may occur in a multi-hole mini-sac

1T‐to‐2H Phase Evolution During Epitaxial Growth of Transition Metal Dichalcogenides
Advanced Materials, EarlyView.During MOCVD growth of MoS2 and WSe2, a transient metallic 1T phase emerges in early, edge‐rich, chalcogen‐deficient domains and declines as the films ultimately coalesce as 2H material. Together, experiments and ReaxFF simulations link domain size, edge stoichiometry, and vacancies to this evolution.

Boundary controllability and source reconstruction in a viscoelastic string under external traction [PDF]
, 2013 Treatises on vibrations devote large space to study the dynamical behavior of an elastic system subject to known external tractions since usually a ``system'' is part of a chain of mechanisms which disturb the ``system'' for example due to the periodic ...
