We consider the three-dimensional Ising model in a L(⊥)×L(∥)×L(∥) cuboid geometry with a finite aspect ratio ρ=L(⊥)/L(∥) and periodic boundary conditions along all directions. For this model the finite-size scaling functions of the excess free energy and thermodynamic Casimir force are evaluated numerically by means of Monte Carlo simulations. The Monte Carlo results compare well with recent fi...

In present work, a compressor configuration is taken from literature which will be studied for aspect ratio (ratio between length of blade to chord length) influence over performance. Performance in the sense is pressure ratio of compressor. The aspect ratio of the blade is an important parameter and has a strong influence on the performance of axial flow compressor. There are so many literatur...

This paper presents a single wafer, all-silicon, high aspect-ratio multi-layer polysilicon micromachining technology that combines deep dry etching of silicon with conventional surface micromachining to realize tens to hundreds of microns thick, high aspect-ratio, electrically isolated polysilicon structures with sub-micron air-gaps. Vertical polysilicon sense electrodes as tall as the main bod...

Monte Carlo simulations of pattern-dependent charging during oxide etching predict that the etch rate scaling with aspect ratio breaks down when surface discharge currents are significant. Under conditions of ion-limited etching and no inhibitor deposition, the etch depth depends on the maximum incident ion energy, reaction threshold, and surface discharge threshold, and is the same irrespectiv...

A simplified process to fabricate high aspect ratio nanostructures in silicon combining electron beam lithography and deep reactive ion etching (DRIE) is presented. A stable process (HARSiN) has been developed without the need for complicated resist/hard mask processing or complex dry etch technologies. This is achieved using commercially available ZEP520A resist from Nippon Zeon Co., Ltd which...

Treemaps are a popular technique to visualize hierarchical data. The input is a weighted tree T where the weight of each node is the sum of the weights of its children. A treemap for T is a hierarchical partition of a rectangle into simply connected regions, usually rectangles. Each region represents a node of T and the area of each region is proportional to the weight of the corresponding node...

The longitudinal aerodynamics of micro aerial vehicles, although not fully understood, have been the subject of several studies in recent years; however, littleworkhasbeendone to investigate the lateral loading. In this experiment, flat-plate wings with rectangular planforms of aspect ratios AR 0.75, 1, 1.5, and 3 and tapered planforms of λ 0.75, 0.5, and 0.25 were placed in the wind tunnel at ...

A theory, which should have widespread application, is developed to treat the statics and slow dynamics of patterns of convective rolls encountered in large aspect ratio Rayleigh-B~nard boxes. For case of presentation the theory is developed using model equations. Wavenumber selection, the shape of patterns, stability and the time dependence resulting from long wavelength instabilities are disc...
