this paper deals with evaluating the thermal behavior of exterior walls in dwellings of a particular place. today, there is a huge increase in constructing multi-storey apartment buildings and single-family houses in the city of yazd, a city with hot dry climate and a rich historical architecture in iran. unfortunately, the new methods that are used nowadays to make the envelopes of these dwell...

In this paper, we study some properties of the exterior tensor product on the category of modules. For this, we prove that the exterior tensor product of two permutation, endo-permutation, endo-trivial and endo-monomial modules are still permutation, endo-permutation endotrivial and endo-monomial modules respectively. Also, we prove that the cap of an exterior tensor product of two modules equa...

A representation formula without pressure term is derived for regular solutions to the 3D time-dependent Oseen system in exterior Lipschitz domains. This valid even if no boundary conditions are imposed. It used order exhibit how velocity decays pointwise space. turns out that rate of this decay depends on $$L^p$$ -integrability time velocity. In addition, work basis successor papers dealing wi...

We describe a polynomial-time algorithm for recognising the exterior square of a matrix. The approach involves manipulation of the equations which relate the entries of a matrix and the entries of its exterior square. Conditions are given which are necessary and sufficient for two matrices to have the same exterior square. The definition of the exterior square of a matrix, and the algorithm use...

In order to evaluate the seismic performance of new-type composite exterior wallboard, a total of six exterior and interior wallboards were incorporated in the experiment of seismic performance. Seismic performance such as the stress process, damage mode, hysteresis and skeleton curve, load-carrying and ductility coefficient, damping and energy dissipation, stiffness degradation as well as mate...

We propose a novel on-surface radiation condition to approximate the outgoing solution Helmholtz equation in exterior of several impenetrable convex obstacles. Based on local approximation Dirichlet-to-Neumann operator and formula for wave propagation, this new formulation simultaneously accounts behavior as well reflections arising from multiple The method involves tangential derivatives only,...

The language of modern mechanics is calculus on manifolds, and exterior calculus is an important part of that. It consists of objects like differential forms, general tensors and vector fields on manifolds, and operators that act on these. While the smooth exterior calculus has a long history going back to Cartan, Lie, Grassmann, Hodge, de Rham and many others, the need for a discrete calculus ...

In this paper, a well-behaved new model of anisotropic compact star in (3+1)-dimensional spacetime has been investigated the background Einstein’s general theory relativity. The developed by choosing [Formula: see text] component as Krori–Barua (KB) ansatz [Krori and Barua J. Phys. A, Math. Gen. 8 (1975) 508]. field equations have solved proper choice anisotropy factor which is physically reaso...
