Large Shearing Motions of Nonlinearly Viscoelastic Slabs
We study the shearing motion of a slab consisting of an incompressible nonlinearly viscoelastic material of diierential type. We describe reasonable general constitutive restrictions that ensure that the strain is bounded during any motion lasting a nite length of time. We brieey sketch how this simple property, which is easily veriied, ensures that the governing initial-boundary-value problems...
متن کاملNonaxisymmetric stability in the shearing sheet approximation
Aims. To quantify the transient growth of nonaxisymmetric perturbations in unstratified magnetized and stratified non-magnetized rotating linear shear flows in the shearing sheet approximation of accretion disc flows. Methods. The Rayleigh quotient in modal approaches for the linearized equations (with time-dependent wavenumber) and the amplitudes from direct shearing sheet simulations using a ...
متن کاملApproximation Solutions for Time-Varying Shortest Path Problem
Abstract. Time-varying network optimization problems have tradition-ally been solved by specialized algorithms. These algorithms have NP-complement time complexity. This paper considers the time-varying short-est path problem, in which can be optimally solved in O(T(m + n)) time,where T is a given integer. For this problem with arbitrary waiting times,we propose an approximation algorithm, whic...
متن کاملResumming the large-N approximation for time evolving quantum systems
In this paper we discuss two methods of resumming the leading and next to leading order in 1/N diagrams for the x 4 O(N) model, which seem to preserve both boundedness and positivity for expectation values of operators at all times. These approximations can be understood either in terms of a truncation to the infinitely coupled Schwinger-Dyson hierarchy of equations, or by choosing a particular...
متن کاملtight frame approximation for multi-frames and super-frames
در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...
