This study investigates the temperature and thermal dose of a tumor in hyperthermia therapy with non-local equilibrium. The thermal model assumes the tissue with blood vessel distribution as a porous media and uses the convection terms instead of perfusion terms in energy conservation equations for both tissue and blood. By using numerical method, this study calculates the temperature and therm...

Model Predictive control is an advanced control technique that has been used to optimize thermal comfort in buildings. Nowadays, the new buildings are characterized by an important inertia as well as low power heating systems. Since the thermal losses are very low, taking into account the intermittent occupancies in the control strategy is questionable. More precisely, in this paper, two model ...

background: this study presents a framework for development of integrated health, safety and ergonomic (hse) in complex critical systems. total ergonomics model considers conventional ergonomics factors as well as management and organizational factors. methods : control room operation and maintenance department of a thermal power plant was chosen as the case of our study. to achieve the above o...

Understanding magnetoresistance, the change in electrical resistance under an external magnetic field, at the atomic level is of great interest both fundamentally and technologically. Graphene and other two-dimensional layered materials provide an unprecedented opportunity to explore magnetoresistance at its nascent stage of structural formation. Here we report an extremely large local magnetor...

singular perturbation problems have been studied by many mathematicians. since the approximate solutions of these problems are as the sum of internal solution (boundary layer area) and external ones, the formation or non-formation of boundary layers should be specified. this paper, investigates this issue for a singular perturbation problem including a first order differential equation with gen...

Some HVAC systems save energy by creating stratified air temperature distributions in which the occupied lower regions are cooler and the upper regions warmer. Comfort standards prescribe a 3°C limit to vertical stratification, independent of where the mean temperature is relative to the comfort zone. This paper evaluates thermal comfort in stratified environments using a model developed to pre...

the residual stresses in composite laminates depend on several factors including the conditions of fabricating process, property of materials, direction and lay-ups of the layers. however the thermo-elastic behavior of composite is one of the most important parameters affecting the magnitude of residual stresses. the elastic properties and residual stresses do not remain constant under cyclic t...

Non-local and non-convex energies represent fundamental interacting effects regulating the complex behavior of many systems in biophysics materials science. We study one dimensional, prototypical schemes able to several biomacromolecules phase transformation phenomena solid mechanics. To elucidate thermal fluctuations on non-local such systems, we consider three models different complexity rely...

The aim of this paper is to study the local Nusselt number of the symmetrical liquid-liquid jets emitting from a nozzle. Equations obtained from theoretical works are arranged in the form of a computerized model. The validity of this model was tested by the data from an experimental paper [1]. After few adjustments the model predicted the experimental data with a reasonable accuracy. Making...
