The permeability of the preform composite materials used in liquid molding processes such as resin transfer molding and structural reaction injection molding is a complex function of weave pattern and packing characteristics. The development of tools for predicting permeability as a function of these parameters is of great industrial importance. Such capability would speed process design and op...

Large quasi-elliptical cylinders are extensively used in ocean engineering. To enhance a better understanding of the hydrodynamic wave force on such during extreme events, series experiments interaction with cylinder were conducted. A waves various heights, periods, and incident directions tested to investigate parameter effect directionality forces structure. The experimental results indicate ...

Birefringent optical waveguides find use in a large number of applications such as coherent optical communication systems, interferometric fiber optic sensors, and polarization sensitive integrated optical devices. These waveguides include various polarization-maintaining optical fibers such as elliptical core fibers, bow tie fibers, and side tunnel fibers and integrated optical waveguides such...

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...

In one of expeditions realized by Missouri Botanical Garden in May 2019, we found a small tree as part the project "Diversity flora and its relationships with soil, wild area Cordillera Azul National Park"; examining botanic samples be carefully realizing respective comparisons, arrived to conclusion that it has different characteristics from others species Virola. Therefore would new fo...

Recent progress in the dynamical analysis of elliptical galaxy kinematics is reviewed. Results reported briefly include (i) the surprisingly uniform anisotropy structure of luminous ellipticals, (ii) their nearly flat (to ∼ 2Re) circular velocity curves, (iii) the Tully-Fisher and M/L − L relations and the connection to the Fundamental Plane, and (iv) the large halo mass densities implied by th...

Ratcheting behavior of steel 304L cylindrical shell under cyclic combined and axial loading are investigated in this paper, numerically. Cylindrical shells were fixed oblique at angle of 20° and normal with respect to the longitudinal direction of the shell and subjected to force-controlled cycling with non-zero mean force, which causes the accumulation of plastic deformation or ratcheting beha...

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...
