A rate-state model for aftershocks triggered by dislocation on a rectangular fault: a review and new insights
aftershocks earthquake triggering fault parameters rate-and-state Omori law
2015/9/8
We compute the static displacement, stress, strain and the Coulomb failure stress produced in
an elastic medium by a finite size rectangular fault after its dislocation with uniform stress drop
but ...
In the present paper a criteria for a rectangular diagram to admit a simplification is given in terms of Legendrian knots. It is shown that there are two types of simplifications which are mutually in...
Nonlinear free flexural vibrations of functionally graded rectangular and skew plates under thermal environments
Functionally graded plate nonlinear free vibration aspect ratio temperature gradient index
2011/9/21
Abstract: The nonlinear formulation developed based on von Karman's assumptions is employed to study the free vibration characteristics of functionally graded material (FGM) plates subjected to therma...
The probability of rectangular unimodular matrices over $\F_q[x]$
Natural density unimodular matrices Riemann’s zeta function q-zeta function finite field polynomial ring
2011/9/13
Abstract: In this note, we compute the probability that a $k\times n$ matrix can be extended to an $n\times n$ invertible matrix over $\F_q[x]$, which turns out to be $(1-q^{k-n})(1-q^{k-1-n})...(1-q^...
Wave approach for the resonances of rectangular and triangular membranes
Wave approach rectangular and triangular
2011/8/31
This study develops a ray technique for determining the resonance frequencies of triangular membranes. The technique is demonstrated for homogenous rectangular and triangular membranes with fixed boun...

2011/1/19
The lowest order nonconforming rectangular element in three dimen-sions involves 54 degrees of freedom for the stress and 12 degrees of freedom for the displacement.
Applications of operational calculus: Equations for rectangular arrays of four and five data
Interpolation shifting operator rectangular data array operational equations
2010/11/1
Selections of equations for four or five data in rectangular array are seldom encountered in textbooks. New methods illustrate polynomial and exponential equations for the two designs. The methods are...
Applications of operational calculus: Rectangular prisms and the estimation of a missing datum
Interpolation data replacement operational equations
2010/9/21
Operational equations can be used for the estimation of data missing from prismatic arrays. This paper continues the discussion of that subject. New interpolating equations for data in prismatic and r...
