Geometry effect on post-dryout heat transfer.
A thorough literature review of the effects of channel shape and spacing devices on post-dryout heat transfer has been performed. Overall, very little information is available for these effects, several experiments were carried out covering only limited flow conditions and geometries. To extend the …

Two-Dimensional Analysis of Narrow Gate Effects in Micron and Submicron Mosfets (Device Simulation, Modeling)
… of the device characteristics due to the geometry effects in narrow gate MOSFETs, such as threshold voltage shift and subthreshold characteristics, are important factors in designing next generation MOS-VLSI circuits. It is well known that numerical methods, using the exact 2-D solutions …

A Computational Model of Aneurysmal Flow at the Abdominal Aorta
… element Windkessel model was coupled to the 3D geometry model of the disease in order to couple inlet flow with outlet pressure. This model resulted in more precise hemodynamic conditions for pulsatile flow: 1- in terms of realistic wall pressure values and pressure curves, 2- realistic geometry …

Study of geometry effects on local corrosion rates for Lbe loop
… another. As a result, an intensive study on the geometry effect is necessary and valuable. In this thesis, this problem was simulated by commercial software STAR-CD. Results provide a good prediction where the highest corrosion rate might occur and how geometry will affect the local corrosion …

Analysis of Electrode Geometric Parameters on AC Impedance Response
… as an active area to investigate electrode geometry effects. Both solid and hollow electrodes were used to explore that type of morphological dependence more precisely. Counter to working electrode distance was also altered while keeping the working electrode effective area constant to …

Measuring Brain Iron In Healthy Controls And Accessing Venous Abnormalities In Parkinson's Disease Using Mri
… is a tissue property that is free from geometry effect and imaging parameters. Except in the thalamus, iron increases over time in the gray matter nuclei. We found iron content decreases as a function of age in thalamus according to the susceptibility measurements. These measured …

Passive methods for suppressing acoustic resonance excitation in shallow rectangular cavities.
… The first passive method considers the edge geometry effect on the phenomenon. Several edge geometries including chamfered, round, and different configurations of spoilers are considered. The effect of the spoilers dimensions is investigated to provide criteria that help designing and …

Strain-induced self-rolled-up semiconductor micro/nanotubes: Fabrication and characterization
… of tubes has been achieved by understanding effects of geometry on tube formation, and perfectly ordered large arrays of tubes were realized. Also, GaAs quantum wells and InAs quantum dots have been embedded in the tube wall, and their optical properties were studied, using the micro-PL …
