in the present study, the effect of porosity on the cathode microstructure (50:50 wt. % lsm: ysz) of a solid oxide fuel cell (sofc) has been examined. a 3-d finite element method for mixed ionic and electronic conducting cathodes (miec) is presented to study the effects of porosity on cell performance. each microstructure was realized using the monte carlo approach with the isotropic type of gr...

the development of materials for language teaching has been retraced from different perspectives. for example, some have identified influences of a social view on designing course books and compiling materials for language classes. the purpose of this article is to focus on the specific case of elt material, its design and priorities in the context of iran. this article also offers a detailed a...

this study aims to deal with a more realistic combined problem of project scheduling and material ordering. the goal is to minimize the total material holding and ordering costs by determining the starting time of activities along with material ordering schedules subject to some constraints. the problem is first mathematically modelled. then a hybrid simulated annealing and genetic algorithm is...

in this paper, a new kind of gripper is designed. this universal gripper is proposed where different objects should be gripped easily, reliably within rapid succession without any feedback. by adding an annular balloon around the granular bag, a lateral force pushes the main membrane and increases the friction force between the bag and the load. according to the acquired test results reported i...

In the present study, the effect of porosity on the cathode microstructure (50:50 wt. % LSM: YSZ) of a Solid Oxide Fuel Cell (SOFC) has been examined. A 3-D finite element method for Mixed Ionic and Electronic Conducting Cathodes (MIEC) is presented to study the effects of porosity on cell performance. Each microstructure was realized using the Monte Carlo approach with the isotropic type of gr...

In this paper, we explore ways in which the results of our studies on emotion communication across cultures (on which we report in the other paper we present at this symposium) can be used as a starting point for material and activity design, within a language socialization approach, and with a view to develop learners’ intercultural competence. Starting from theoretical and pedagogical conside...

— The microstructure identification problem is treated : given certain phases in given volume fractions, how to mix them in aperiodic cell so that the effective material constants of the periodic composite lie the closest possible to certain prescribed values ? The problem is studied for the linear conduction équation. It is stated in terms of optimal con trol theory ; the admissible micro geom...

In the computer graphics production environment, artists often must tweak specific lighting and material parameters to match a mind’s eye vision of the appearance of a 3D scene. However, the interaction between a material and a lighting environment is often too complex to cognitively predict without visualization. Therefore, artists operate in a design cycle, where they tweak the parameters, wa...
