The propagation of shear waves in an anisotropic fluid saturated porous layer over a prestressed semi-infinite homogeneous elastic half-space lying under an elastic homogeneous layer with irregularity present at the interface with rigid boundary has been studied. The rectangular irregularity has been taken in the half-space. The dispersion equation for shear waves is derived by using the pertur...

The propagation of surface waves in a fluid- saturated porous isotropic layer over a semi-infinite homogeneous elastic medium with an irregularity for free and rigid interfaces have been studied. The rectangular irregularity has been taken in the half-space. The dispersion equation for Love waves is derived by simple mathematical techniques followed by Fourier transformations.  It can be seen t...

Despite abundant research on the distribution of glottal stops and glottalization in English and other languages, it is still unclear which factors matter most in predicting where glottal stops occur. In this study, logistic mixed-effects regression modeling is used to predict the occurrence of word-initial full glottal stops vs. no voicing irregularity. The results indicate that prominence and...

The main aim of this contribution is comparison of method for evaluation of nonwovens surface uniformity based on the data in the form of rectangular arrays (quadrat method). These data can be obtained from digital images where the variation of mass is characterizes by the variation of grey level image. The evaluation of uniformity is based on the variation coefficient model, ANOVA model and sp...

The approximation of road distances by the weighted lp distance measure has been studied in a series of papers ([5, 6], etc.) and it is argued with empirical study that lp distances weighted by an inflation factor tailored to given regions can better describe the irregularity in the transportation networks such as hill, bends, and are therefore superior to the weighted rectangular and Euclidean...

Objective: The objective is to obtain the stresses due to strip loading in orthotropic plate lying over an irregular isotropic elastic medium. Methods: Anti-plane strain problem with perfect bonding boundary conditions following by Fourier Transformation on the equilibrium equation are used to obtain the solution. The deformation field due to shear line load at any point of the medium consistin...

The paper presents certain problems related to the lubrication of textured surfaces. It was noted that for a specific load, effectiveness will depend on shape, size and mutual distribution texture’s elements. Proposals determining irregularity parameters were presented textures with rectangular mesh round recesses. experimental part laser texturing methodology, tribological testing methodology ...

The El Niño/Southern Oscillation (ENSO) phenomenon is the dominant climatic fluctuation on interannual time scales. It is an irregular oscillation with a distinctive broadband spectrum. In this article, we discuss recent theories that seek to explain this irregularity. Particular attention is paid to explanations that involve the stochastic forcing of the slow ocean modes by fast atmospheric tr...

Purpose: This study was to investigate the effect of irregularity in shape of field size of electron beam on the percentage depth dose and the output factor. Study the variety of the Percentage Depth Dose (PDD) and the output factors for rectangular and small field sizes when one of field dimensions less than the Practical Range (Rp) of the electron energy used. Compare the measured output fact...
