The horizontal amplitude screening effects of a rectangular strip in-filled trench

Journal of the Chinese Institute of Engineers, 2013
The horizontal amplitude screening effects of an in-filled trench are solved using the boundary element method in the frequency domain. Dimensionless parametric studies are performed to assess the screening effects of the trench in terms of the geometry, in-filled material, foundational embedment, and shear wave velocity ratio of the in-filled material

Parameters of jets out of rectangular nozzles when they are free or near a screen

Fluid Dynamics, 1979
The results are given of an experimental determination of the parameters of jets out of rectangular nozzles. The distributions of the mean velocity and an impurity concentration were measured. The rearrangement of the jet flow associated with the three-dimensional structure of the jet and interaction of the jet and a screen was investigated.

Basic study on the rectangular numeric keys for touch screen.

Journal of human ergology, 2000
The present study was conducted to examine the optimum inter-key spacing of numeric rectangular keys for touch screens. Six male students (22-25 years old) and three female students (21-24 years old) participated in the experiment. Each subject performed the data entry task using rectangular keys of touch devices.

Transmission in a rectangular waveguide loaded with an arbitrary number of capacitive screens

Applied Scientific Research, Section B, 1958
Green’s theorem is applied to individual domains consisting of the walls of a rectangular waveguide and two neighbouring slotted capacitive screens. In addition this theorem is applied to the two end domains, that is, the one containing the incident field and the other containing the transmitted field only.

Effect of screens on the turbulent flow in the quiescent zone of a rectangular aquaculture raceway

Aquacultural Engineering, 2013
Abstract An acoustic Doppler velocimeter (ADV) was used to measure detailed vertical profiles of mean velocity and (for the first time) turbulence characteristics at the center of the quiescent zone (QZ) of operating aquaculture raceways. Instantaneous velocities were recorded at 10 Hz and averaged over a 360-s time interval in order to derive mean ...

Transmission Resonance Phenomena for a Narrow Rectangular Slot in Thick Conducting Screen

2018 Progress in Electromagnetics Research Symposium (PIERS-Toyama), 2018
Two types of transmission resonance phenomena which are observed in a narrow rectangular slot structure in thick conducting screen is dealt with along with experimental verification. Some discussions are also given in connection with the transmission resonance phenomena occurring in the cylindrical hole structure in the real metal, which was once ...

Microwave absorption enhancement of rectangular activated carbon fibers screen composites

Composites Part B: Engineering, 2015
Abstract The radar absorbing materials composited of activated carbon fibers (ACF) as wave-absorber and glass fibers (GF) as impedance modifier were successfully prepared. The structure parameters of rectangular ACF felt screen, the influences of GF-piece and the reflection properties were investigated.

Efficient MLFMA analysis of coupled rectangular and circular apertures in a finite screen

IEEE MTT-S International Microwave Symposium Digest, 2003, 2003
A multilevel fast multipole algorithm (MLFMA) is introduced for the efficient analysis of coupled rectangular and circular apertures of different size within a finite conducting screen. The electric field integral equation (EFIE) is written in terms of mixed potential formulation.

Electromagnetic plane wave scattering by a rectangular hole in a thick conducting screen

2017 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2017
Kirchhoff approximation method has been applied to formulate analytically an electromagnetic plane wave diffraction by a rectangular hole in a thick conducting screen. This three-dimensional structure is regarded as an open-ended rectangular waveguide cavity.
