A hereditary torsion theory is simple if it is generated by a class of simple modules. There is a fairly large class of rings, including e.g. the artinian rings, for which all hereditary torsion theories are simple. Therefore it is of a certain interest to study simple torsion theories ...
We show that the nonlinear bending-torsion theory for inextensible rods arises as $\\Gamma$ -limit of three-dimensional nonlinear elasticity. MG Mora,S Müller - 《Calculus of Variations & Partial Differential Equations》 被引量: 107发表: 2003年 On the Theory of Rods. I. Derivations from the...
We implement an algorithm RSHT (random simple-homotopy) to study the simple-homotopy types of simplicial complexes, with a particular focus on contractible
The theory of permutation orbifolds is reviewed and applied to the study of symmetric product orbifolds and the congruence subgroup problem. The issue of d... P Bantay - 《Physics》 被引量: 21发表: 2001年 Torsion-free, genus-one, congruence subgroups of PSL (2, R) and multiplicative η-...
These walking effort outcomes were derived from a compass gait model and space curve displacement, acceleration and differential geometry theory. The walking effort outcomes were primarily calculated from the motion of a point on or in the rigid body pelvis as a patient walked cyclically. These ...
We finally discuss the results for a selection of geometrical ratios, and the viability of simplified approaches based on beam theory.doi:10.1016/j.ijmecsci.2018.05.027E. BertocchiS. MantovaniM. CiavarellaInternational Journal of Mechanical Sciences...

In word embedding theory, the embedding layer provides a measure of similarity between words. However, from the path probability representation, it is unclear how the embedding layer works since the derivation can be done without embedding vectorsx. To have an understanding toQlmin the first-order...
8.Based on wave propagation theory, the wave solution of a simply supported beam with a crack is investigated.基于结构振动波传播理论,讨论了在简谐力作用下,裂纹简支梁的弯曲波动解。 9.A few examples from different periods show that the simple design of Egyptian doorways conforms to a harmonic anal...
product of a stable simple AF-algebra with a Z-action determined by an automorphism, which maps a projection in the algebra onto a proper subprojection, is proved to consist of simple, purely infinite C*-algebras, and a specific subclass of it is proved to be classified by K-theory. This...
