On the relation of Thomas rotation and angular velocity of reference frames [PDF]

, 2006
In the extensive literature dealing with the relativistic phenomenon of Thomas rotation several methods have been developed for calculating the Thomas rotation angle of a gyroscope along a circular world line.

Drones for parcel and passenger transportation: A literature review [PDF]

, 2020
Delivery drones and ‘air taxis’ are currently among the most intensely discussed emerging technologies, likely to expand mobility into the ‘third dimension’ of low-level airspace.

A Note on Smooth Points in Orlicz Sequence Spaces

Journal of Harbin University of Science and Technology, 2021
In this paper，when φ( u) /u→A( u→∞ ) the criterion of smooth points in Orlicz sequence space generated by general Orlicz functions and the equivalence conditions of smooth points with very smooth points and strong smooth points are given. On this basis，

Absolute Time Derivatives [PDF]

, 2006
A four dimensional treatment of nonrelativistic space-time gives a natural frame to deal with objective time derivatives. In this framework some well known objective time derivatives of continuum mechanics appear as Lie-derivatives.

Hilbert space structure and classical limit of the low energy sector of U(N) quantum Hall ferromagnets

SciPost Physics Proceedings, 2023
Using the Lieb–Mattis ordering theorem of electronic energy levels, we identify and construct the Hilbert space of the low energy sector of U(N) quantum Hall/Heisenberg ferromagnets at filling factor M for L Landau/lattice sites.

Weak completeness of the Bourbaki quasi-uniformity

Applied General Topology, 2001
The concept of semicompleteness (weaker than half-completeness) is defined for the Bourbaki quasi-uniformity of the hyperspace of a quasi-uniform space.

Diffusion in Stationary Flow from Mesoscopic Non-equilibrium Thermodynamics [PDF]

, 2001
We analyze the diffusion of a Brownian particle in a fluid under stationary flow. By using the scheme of non-equilibrium thermodynamics in phase space, we obtain the Fokker-Planck equation which is compared with others derived from kinetic theory and ...

On 2 - normed space valued paranormed null sequence space

Bibechana, 2013
In this paper we introduce and study a new class c0 ( S, α‾ , u‾ , ||. , .|| ) of sequences with values in 2- normed space as a generalization of basic null sequence space c0. We investigate some conditions pertaining to the containment relations of the

Embedding into discretely absolutely star-Lindelöf spaces II

Applied General Topology, 2009
A space X is discretely absolutely star-Lindelöf if for every open cover U of X and every dense subset D of X, there exists a countable subset F of D such that F is discrete closed in X and St(F, U) = X, where St(F, U) = S{U ∈ U : U ∩F 6= Ø}.
