Bernd Finkbeiner, Hazem Torfah
2017 Lecture Notes in Computer Science  
We study the distribution of lineartime models by investigating the density of linear-time properties over the space of ultimately periodic words.  ...  We investigate the problem of computing the density for both linear-time properties in general and for the important special case of ωregular properties.  ...  The Density of Linear-time Properties For a given linear-time property ϕ, the density function of ϕ gives the distribution of models of ϕ for increasing bounds n.

Prediction of Compression of Knitted Orthopaedic Supports by Inlay-Yarn Properties

2014 Medžiagotyra  
The influence of linear density of elastic PU core on tensile force increases by increasing elongation value of threads.  ...  When influence of inlay-yarn linear density and number of threads on tensile force is determined it is possible to predict influence of inlay-yarn properties on compression properties of knitted orthopaedic  ...  In area of low elongation (50 %), the tensile force increases approximately 13 times when the linear density of PU core thread increases approximately 18 times.  ...

Rheological Properties of a Natural Estuarine Mud

Thierry Aubry, Tolotrahasiina Razafinimaro, Ricardo Silva Jacinto, Philippe Bassoulet
2003 Applied Rheology  
In this paper, the linear and non-linear rheological properties of estuarine cohesive sediments were investigated. The density of the sediments has been determined by pycnometry.  ...  For all samples tested, four different rheological transitions have been determined and all material properties have been shown to be satisfactorily fitted by exponential functions of the density.  ...  As far as linear rheological properties of this material are concerned, this work shows that the density dependence of the Newtonian viscosity h 0 , and the linear viscoelastic moduli G' 0 and G'' 0 can  ...

Evaluating the origins of the secondary bias based on the correlation of halo properties with the linear density field [article]

Xiaoyu Wang, Huiyuan Wang, H.J. Mo, JingJing Shi, Yipeng Jing
2021 arXiv   pre-print
We find that the secondary bias is the secondary effect of the correlations of halo properties with the linear density estimated at the same comoving scale.  ...  Using two sets of large N-body simulations, we study the origin of the correlations of halo assembly time (z_ f), concentration (v_ max/v_ 200) and spin (λ) with the large-scale evolved density field at  ...  The work is also supported by the Supercomputer Center of University of Science and Technology of China.  ...

Dynamical Mappings of Density Operators in Quantum Mechanics. II. Time Dependent Mappings

Thomas F. Jordan, Mark A. Pinsky, E. C. G. Sudarshan
1962 Journal of Mathematical Physics  
The most general continuous time-dependent evolution of a physical system is represented by a continuous one-parameter semi-group of linear mappings of density operators to density operators.  ...  This proof does not assume that the absolute values of inner products of state vectors or "transition probabilities" are preserved but deduces this fact from the requirement that density operators are  ...  ACKNOWLEDGMENT We would like to acknowledge the pleasure of discussing some of these topics with Professor J. E. Moyal of the Institute of Advanced Studies, Australian National University.  ...
