Study of permeability of Fibrous Composites is important in several natural and industrial processes in mechanical engineering. In this study, a comprehensive mathematical model is presented for calculation of normal permeability of ordered elliptical fibrous media. An innovative scale-analysis technique is employed for determining the normal permeability of elliptical fibrous media. In this te...

An elastic analysis is presented for the tensile stretching and bending of a plate containing a surface crack penetrating part-through the thickness, Fig. 1. The treatment is approximate, in that the two-dimensional generalized plane stress and KirchhoffPoisson plate bending theories are employed, with the part-through cracked section represented as a continuous line spring. The spring has both...

A liquid cooling plate structure with multiple channels is proposed for linear synchronous motor in this paper. Firstly, a conjugate heat dissipation model established, and coupling analysis fluid temperature fields performed by finite volume method different channel numbers section shapes. The simulation results show that, the capacity of observably improved, especially 6-channels elliptical s...

different languages are classified in different types according to different elliptical positions in coordinate sentences. in the following, i shall briefly outline this typology and then show the status of persian in this hierarchy. moreover, i will demonstrate that two functional factors; ease of processing and temporal order, are in competition to specify the elliptical positions in these se...

In his 1985 article (“Projection pursuit”), Huber demonstrates the interest of his method to estimate a density from a data set in a simple given case. He considers the factorization of density through a Gaussian component and some residual density. Huber’s work is based on maximizing Kullback–Leibler divergence. Our proposal leads to a new algorithm. Furthermore, we will also consider the case...

This paper describes a model for the analysis of multilayered chiral structures containing planar electric and magnetic scattering elements of arbitrary shape, illuminated by an elliptically polarized plane wave. The particular case of a single chiral layer is analyzed and the scattering matrices for single and dual electric and/or magnetic dipole distributions are derived in an original way. A...

To explore the anti-penetration performance of specially shaped ceramic/metal composite armor, such an armor is designed and fabricated using a semi-cylindrical projectile resistant ceramic metal back plate, its for 12.7 mm armor-piercing incendiary (API) (also known as 0.50 caliber API projectile) investigated experimentally numerically. The results show that due to significant attitude deflec...

This paper summarizes Kormendy et al. (2009, ApJS, in press, arXiv:0810.1681). We confirm that spheroidal galaxies have fundamental plane correlations that are almost perpendicular to those for bulges and ellipticals. Spheroidals are not dwarf ellipticals. They are structurally similar to late-type galaxies. We suggest that they are defunct (“red and dead”) late-type galaxies transformed by a v...

In this study, the heat transfer characteristics of flat plate collectors with circular and elliptical serpentine tubes are theoretically analyzed compared in terms m˙, Re, Nu, hfi, FR, Qu, μTh under various water flow rates standard test conditions. The results reveal that maximum correspondence to design 56% turbulent flow, minimum 47% for cross-section laminar flow. addition, it was found hi...
