Dynamics of collapsing and exploding Bose-Einstein condensed vortex state [PDF]
, 2002 Using the time-dependent mean-field Gross-Pitaevskii equation we study the dynamics of small repulsive Bose-Einstein condensed vortex states of ^{85}Rb atoms in a cylindrical trap with low angular momentum hbar L per atom (L

Evaluating Spatial Resolution and Channel Capacity of Sparse Cylindrical Arrays for Massive MIMO
IEEE Access, 2017 How to design antenna arrays plays an important role in wireless communications, especially when there are hundreds of antennas. In massive multiple-input and multiple-output (MIMO), if the number of antennas and RF chains are increasing, the channel ...

Izvestiya. Ferrous Metallurgy, 2019 To restore the shape of curved low-rigid cylindrical details such as shafts and axles, bending straightening under distributed loading is proposed, followed by hardening of the billet using surface plastic deformation based on transverse cheesing of it by flat plates.

Energies, 2022 Electrical models of battery cells are used in simulations to represent batteries’ behavior in various fields of research and development involving battery cells and systems. Electrical equivalent circuit models, either linear or nonlinear, are commonly used for this purpose and are presented in this article. Various commercially available cylindrical,

Detailed experimental and numerical analysis of a cylindrical cup deep drawing: Pros and cons of using solid-shell elements [PDF]
International Journal of Material Forming, 2017 The Swift test was originally proposed as a formability test to reproduce the conditions observed in deep drawing operations. This test consists on forming a cylindrical cup from a circular blank, using a flat bottom cylindrical punch and has been extensively studied using both analytical and numerical methods.

, 2022 We study equilibrium configurations of dsDNA in a cylindrical viral capsid. The state of the encapsidated DNA consists of a disordered inner core enclosed by an ordered outer region, next to the capsid wall. The DNA configuration is described by a unit helical vector field, tangent to an associated centre curve, passing through properly selected ...

, 2004 We investigate in detail the special case of an infinitely thin static cylindrical shell composed of counter-rotating photons on circular geodetical paths separating two distinct parts of Minkowski spacetimes--one inside and the other outside the shell ...

Gravitational waves propagating into Friedmann--Robertson--Walker universes [PDF]
, 1996 We consider space-times with two isometries which represent gravitational waves with distinct wavefronts which propagate into exact Friedmann-Robertson-Walker (FRW) universes.
