Analytical solutions are presented for velocity and temperature distributions of laminar fully developed flow of Newtonian, constant property fluids in micro/minichannels for a wide variety of cross-sections. The considered geometries include hyper-elliptical channels and regular polygon ducts, which covers several common shapes. The analysis is carried out under the conditions of constant axia...

The optimal focusing arrangement for second-harmonic generation is a compromise between the focal intensity and the depth of focus (confocal parameter) within the crystal. In the absence of birefringence (noncritical phasematching), the fundamental beam should have a circular cross section and a confocal parameter of 0.35 of the crystal’s length.1 Angle-tuned (critical) phase matching causes th...

A comparison between reported analytical results with experimental data of the magnetic flux density on cylindrical tin inclusions of elliptical cross-section embedded in a copper matrix under external thermal excitation is presented. By changing the aspect ratios b/a designated by e of the elliptical inclusions, a wide range of real situation such as slender inclusions can be simulated. The as...

Iodine molecules confined in the elliptical nanochannels of AlPO4-11 crystals can only rotate in the plane passing through the major axis of the elliptical cross-section due to size confinement. This leads to different dynamic behaviors of iodine from those confined in round channels of AlPO4-5 crystals under ambient conditions. In this work, we use high pressure technology to manipulate the na...

In this research, the behavior and characteristics of the wake of flow in an elliptic cylinder with zero angle of attack in the presence of a tripping wire were investigated experimentally. For this purpose, the used an Aluminum cylinder with an elliptical cross section of the major and minor axis of 42.4 mm and 21.2 mm, respectively, and of the height of 390 mm. The cylinder model was examined...

The impact of the elasticity polymer filler a three-layer cylindrical structure normal elliptical cross-section on its stress-strain state under internal impulse loading was studied. Determined values and distribution deflections stresses in sections S1 S2. finite-element method calculating (SSS) such by software-calculation complex Fimap with NX Nastran applied. Conclusions were made regarding...

Subperiosteal bone-bonding devices have been proposed for less invasive treatments in orthodontics. The device is osseointegrated onto a bone surface without fixation screws and is expected to rapidly attain a bone-bonding strength that successfully meets clinical performance. Hence, the device's optimum shape for rapid and strong bone bonding was examined in this study by finite element analys...

Binary stochastic neurons (BSNs) are excellent activators for machine learning. An ideal platform implementing them low- or zero-energy-barrier nanomagnets (LBMs) possessing in-plane anisotropy (e.g. circular slightly elliptical disks) whose fluctuating magnetization encodes a probabilistic (p-) bit. Here, we show that such BSN's activation function, the pinning current (which pins output to pa...

We present evidence for non-Gaussian velocity fields within the cores of luminous elliptical galaxies. This evidence is based on high signal-to-noise ratio, medium-resolution spectroscopy of the cores of early-type members of the Virgo and Coma Clusters obtained with the Wisconsin-Indiana-Yale-NOAO 3.5 m telescope. The Virgo data were acquired using an integral-field unit (DensePak), which allo...
