Nonnegative basis of a lattice : Discrete Mathematics and ApplicationsIgor V. Cherednick
We study the computational complexity of various inverse problems in discrete tomography. These questions are motivated by demands from the material scienc... RJ Gardner,P Gritzmann,D Prangenberg - 《Discrete Mathematics》 被引量: 260发表: 1999年 加载更多来源...
Finally, we propose two (as far as we know) still unanswered questions. Question 9.12. Does there exist a locally optimal solution to the lattice packing- covering problem which is not isolated? Note that a positive answer to the following question would imply the existence of non-isolated ...
Exercises are integrated throughout the text, and frequently asked questions about the method are dealt with in a special section at the beginning. In the book itself and through its web page, readers can find example codes showing how the LB method can be implemented efficiently on a variety...
Indeed, many experimental observations, regarding the executionof the algorithms and the geometry of their outputs, pose challenging questions,which r... B Vallée,A Vera - Springer Berlin Heidelberg 被引量: 2发表: 2017年 A morphological, topological and mechanical investigation of gyroid, spinodo...
It is natural to consider the averages of the type (1) from a probabilistic point of view and ask questions such as whether they satisfy a large deviation principle, whether associated extremes have classical extreme value behavior, etc. These questions are far from obvious, since even in the...
in the vascular porosity and lacunar-canalicular porosities. Poroelasticity and electrokinetics can be used as an efficient tool in the experimental study of local bone fluid flow, which in turn deals with quite a few questions regarding bone mineralization and mechanosensory system (Kapellos et al....
Questions on the transcendence and linear independence of periods have a long history going back at least to Euler. We shall first give in this note a hist... G Wüstholz 被引量: 0发表: 2012年 Of windows and country walks: frames of space and movement in 1990s Austen adaptations Bem's...
Motivated by the recent experiment on bosonic mixtures of atoms and molecules, we investigate pairing superfluid–insulator (SI) transition for bosonic mixtures of atoms and molecules in a one-dimensional optical lattice, which is described by an extended Bose–Hubbard model with atom–molecule conserv...
All the macroscopic variables, such as velocity, pressure, and temperature, are obtained in a region of interest by solving the N–S equations with the given boundary conditions. Although finding the macroscopic variables from the governing macroscopic equations (i.e., N–S equations) are ...
