We present a method for constructing a teleological model of a drawing of a physical device through analogical transfer of the teleological model of the same device in an almost identical drawing. A source case, in this method, contains both a 2-D vector-graphics line drawing of a physical device and a teleological model of the device called a Drawing-Shape-Structure-Behavior-Function (DSSBF) m...

In RF power device design, much of the analysis is based on measurements. Complete analysis by simulation is often avoided because the high-frequency, largesignal operation makes device simulation unsuitable, and the difficulties in obtaining a good physical compact model make circuit simulation inaccurate. This work presents a methodology that overcomes these limitations by utilizing a combina...

In this paper the simulation and design of a quantum-film electro-optic switch is considered. This photonic device, is made from a new organic dipolar material called MNA or 2-methyl-4 nitroaniline, which possesses a high merit in comparison with it's inorganic counterparts (e.g. LiNbO3, GaAs, InSb, Quartz, etc). Montecarlo method is used to simulate the photon-it-electron interaction in this m...

The mechanical properties of microscopic particles have been a heated research object for it takes the deformation of micro-beads in the microfluidic environment into account. Sufficient knowledge on mechanical properties of micro-beads would lead to better device design and application for cell mechanics, tissue engineering, etc. The physical properties of alginate beads were examined both in ...

abstract background: beginning and continuing pregnancy with obesity and being overweight has some known side effects for the mother and the fetus. preventing these complications requires medical interventions before pregnancy. because designing health improvement interventions requires understanding of the related factors of the behavior, the aim of this study was to determine the relation bet...

This paper presents a technique for evaluating the performance of biomedical devices by combining physical (mechanical) testing with a numerical, computerised model of a biological system. This technique is developed for evaluation of a cardiac assist device prior to in vivo trials. This device will wrap around a failing heart and provide physical beating assistance (dynamic cardiac compression...

In this work, the physical based device model of AlGaN/GaN high electron mobility transistors (HEMTs) has been established and the corresponding device operation behavior has been investigated also by using Sentaurus TCAD from Synopsys. Advanced AlGaN/GaN hetero-structures with GaN cap layer and AlN spacer have been considered and the GaN cap layer and AlN spacer are found taking important role...

Modeling of memristor devices is essential for memristor based circuit and system design. This chapter presents a review of existing memristor modeling techniques and provides simulations that compare several existing models to published memristor characterization data. A discussion of existing models is presented that explains how the equations of each relate to physical device behaviors. The ...

The determination of the thermal comfort indices needs the evaluating devices. The physical measured parameters of the milieu input in this device. We measure air temperature of the area, temperature of the surfaces of walls, floor and the ceiling –medium radiant temperature, air flow velocity and air moisture. Other parameters are the date of his clothes and his physical activity. Outputs of t...
