We propose an edge averaged finite element (EAFE) discretization to solve the Heat-PNP (Poisson-Nernst-Planck) equations approximately. Our method enforces positivity of computed charged density functions and temperature function. Also thermodynamic consistent discrete energy estimate which resembles second law system is prescribed. Numerical examples are provided.

2 The study shows that the magnitude of global surface warming greatly depends on the meridional distribution of surface thermal forcing. An atmospheric model coupled to an aquaplanet slab mixed layer ocean is perturbed by prescribing heating to the ocean mixed layer. The heating is distributed uniformly globally or confined to narrow tropical or polar bands, and the amplitude is adjusted to en...

Numerical time integrations of a general circulation model of the atmosphere are performed with both modern and ice age boundary conditions. It is shown that the climate of continental portions of the tropics in the ice age simulation is much drier than that of the modern climate simulation. According to comparisons of results from the two experiments, tropical continental aridity of the ice ag...

Error feedback control (in the presence of input constraints) is considered for a class of exothermic chemical reactor models. The primary control objective is regulation of a setpoint temperature T∗ with prescribed accuracy: given ¿ 0 (arbitrarily small), ensure that, for every admissible system and reference setpoint, the regulation error e = T − T∗ is ultimately smaller than (that is, ‖e(t)‖...

We have developed a simple, analytically tractable radiativexonvective model of the tropical climate system that includes an explicit moisture budget, a simple convection parametrization, a simple but physically based radiation parametrization, and interactive clouds. The underlying surface is assumed to be ocean. The model includes prognostic equations for the sea surface temperature and the v...

In this study, a viscoelastic damper (VED) is developed by using a VE material with low temperature dependence, and a performance-based placement-design procedure of VEDs is developed for finding the story-wise distribution of VEDs in a building such that each peak interstory drift coincides with the prescribed value. The mechanical properties of the employed VEDs dependence on amplitude and fr...

background: drug utilization studies are helpful in understanding the current practice. we have conducted a retrospective study to evaluate the relevant use of a group of most commonly prescribed antibiotics in a teaching hospital in iran.  the results of this study may be of help for clinicians to improve the patient care. methods: patients who received parenteral ceftazidim, vancomycin and am...
