Casting behavior of the string structures considering axial elongation

Nihon Kikai Gakkai ronbunshu, 2019
A flexible string is used at various places. Typical examples are a cable for power transmission and communication and a wire for cranes and elevators. In addition, there are the uses such as a fly-fishing line, climbing rope and a mowing machine to cut ...

Holographic superfluids as duals of rotating black strings

, 2010
We study the breaking of an Abelian symmetry close to the horizon of an uncharged rotating Anti-de Sitter black string in 3+1 dimensions. The boundary theory living on R^2 x S^1 has no rotation, but a magnetic field that is aligned with the axis of the ...

No-Drag String Configurations for Steadily Moving Quark-Antiquark Pairs in a Thermal Bath [PDF]

, 2006
We investigate the behavior of stationary string configurations on a five-dimensional AdS black hole background which correspond to quark-antiquark pairs steadily moving in an N=4 super Yang-Mills thermal bath.

Influence of Coiled Tubing Size and Lowering Depth on Velocity String Operation

Shiyou jixie, 2020
Aiming to resolve the problem of liquid loading at the well bottom during gas well production and increase the well production by installing coiled tubing as a velocity string, a study on the influence of coiled tubing size and lowering depth on velocity

Neutrino currents in wakes of cosmic strings

European Physical Journal C: Particles and Fields, 2020
Neutrinos rotating around Abelian Higgs strings will generate a neutral current close to the string. As the string moves through the cosmic plasma, the velocity kick generated by the motion of the string will enhance the neutrino current in the wake ...

D-brane recoil

, 1996
It is shown that there are logarithmic operators in D-brane backgrounds that lead to infrared divergences in open string loop amplitudes. These divergences can be cancelled by changing the closed string background by operators that correspond to the D ...

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

Advanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Design and Application of Algorithm Architecture of Gas-liquid Two-phase Flow during Velocity String Operation

Shiyou jixie, 2020
Aiming at the design and application of the gas-liquid two-phase flow algorithm architecture of the J curve and the IPR curve during production in the velocity string and the annulus, based on the theory of critical liquid carrying flow and flow channel ...

Scattering of Straight Cosmic Strings by Black Holes: Weak Field Approximation

, 1998
The scattering of a straight, infinitely long string moving with velocity $v$ by a black hole is considered. We analyze the weak-field case, where the impact parameter ($b_{imp}$) is large, and obtain exact solutions to the equations of motion.
