We use Monte Carlo simulations to study the static and dynamical properties of a Potts glass with infinite range Gaussian distributed exchange interactions for a broad range of temperature and system size up to N = 2560 spins. The results are compatible with a critical divergence of the relaxation time τ at the theoretically predicted dynamical transition temperature TD, τ ∝ (T−TD) −∆ with ∆ ≈ ...
ناکاملی هندسی در ستون ها از مواردی می باشد که وجود آن در اعضای سازه ای را نمی توان نادیده گرفت، در هر عضو سازه ای ناکاملی هندسی هر چند بسیار کوچک وجود خواهد داشت از این رو بررسی تاثیرات این ناکاملی ها و همچنین پیدا کردن مقدار مجاز برای آنها در طراحی سازه های فولادی دارای اهمیت خاصی می باشد. هدف این پژوهش بررسی رفتار قاب های فولادی با ناکاملی در مختصات گرهی به میزان 3، 6 و 9 میلی متر بوده که برا...
A local Hawking temperature was recently derived for any future outer trapping horizon in spherical symmetry, using a Hamilton-Jacobi tunneling method, and is given by a dynamical surface gravity as defined geometrically. Descriptions are given of the operational meaning of the temperature, in terms of what observers measure, and its relation to the usual Hawking temperature for static black ho...
Mechanical characterization of a two-dimensional Thermal Energy Storage (TES) composite structure that combines the heat storage capability with structural functionality was carried out experimentally. Static and fatigue experiments were conducted for the composite structure under three-point bending at both room temperature and elevated temperature. An energy method model was developed to pred...
The gas-sensing behaviour based on a dynamic measurement method of a single SnO2 gas sensor was investigated by comparison with the static measurement. The influencing factors of nonlinear response such as modulation temperature, duty ratio, heating waveform (rectangular, sinusoidal, saw-tooth, pulse, etc.) were also studied. Experimental data showed that temperature was the most essential fact...
We describe the static dielectric response of ferroelastic-dielectric microcomposites. Its dependence on temperature, pressure and concentration is considered for smaller concentrations and for temperatures above the critical temperature. We have found a qualitative agreement with existing experimental data for Al2(WO4)3.
I review recent developements in lattice QCD at finite temperature, including the determination of the transition temperature Tc, equation of state and diffenet static screening lengths. The lattice data suggest that at temperatures above 1.5Tc the quark gluon plasma can be considered as gas consisting of quarks and gluons.
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
The temperature-dependent ‘H and 13C NMR spect_ra of (hS-C.r.~Hs)3Rh3 (CO)C6H&sC6Hs support the view that this molecule is fluxional in solution at room temperature but is in a frozen conformation at -88”; NMR data of (h’-CsHs)sRh3 (CO) CeFsCsC6F5 indicate that this molecule appears to be static at room temperature and fluxional at elevated temperatures. The NMR data are consistent with structu...
The static stability of the extratropical troposphere is examined in two atmospheric general circulation models (GCM’s) over idealized boundary conditions, with emphasis on the role of moisture in determining the midlatitude stability. The determination of the static stability is compared within two models: an idealized moist model with simplified representations of radiative transfer and other...
