determination of physical properties of municipal waste compost is necessary to obtain the parameters related to designing and constructing a suitable pelleting machine for producing compost pellets. the purpose of this study is determining some physical properties such as; bulk density, coefficient of friction, porosity, angle of repose for compost and density and expansion for compost pellets...

sudden pipe expansions have been known as efficient hydraulic energy dissipaters for a long time. the complex phenomenon of flow separation and velocity discontinuity at the interface of incoming jet and the recirculation flow, results in intensive shear and tensile rupture of the fluid and the associated destructive phenomenon of cavitation. this paper focuses on aeration in sudden pipe expans...

Purpose – The purpose of this paper is to propose a framework and system to address the inability to discover new and authentic learning material and the lack of a single access point for search and browsing of remote learning object repositories (LORs). Design/methodology/approach – The authors develop a framework for keyword-based query expansion using SKOS domain terminologies and implement ...

We study the Poisson equation in a perforated domain with homogeneous Dirichlet boundary conditions. The size of perforations is denoted by ε > 0, and proportional to distance between neighbouring perforations. In periodic case, homogenized problem (obtained limit → 0) well understood (see (Rocky Mountain J. Math. 10 (1980) 125–140)). extend these results non-periodic case which defined as l...

STATEMENT OF PROBLEM Resinous die materials have several important advantages including strength, abrasion resistance, and detail reproduction. Despite these advantages, the shrinkage of resinous die materials during polymerization has limited their widespread acceptance. PURPOSE This study determined whether a retarded setting reaction could improve the accuracy of an epoxy resin die system,...

BACKGROUND Although a residual intimal tear may contribute to the dilatation of the descending aorta following surgical repair of acute type I aortic dissection (AD), its causal relationship has not been elucidated by clinical data due to the limited resolution of imaging modalities. METHODS This study enrolled 41 patients (age, 55.2±11.9 years) who were evaluated with dual-source computed to...

Given a polynomial of even degree $D(t)$ with complex coefficients, we consider the continued fraction expansion $\sqrt{D(t)}$. In this setting, it has been shown by Zannier that sequence degrees partial quotients $\sqrt{D(t)}$ is eventually periodic, when itself not. article, work out in detail case which curve $y^2=D(t)$ genus $0$, establishing explicit geometric conditions corresponding to a...

This paper investigates the asymptotic expansion for the size of block codes defined for the additive white Gaussian noise (AWGN) channel with feedback under the following setting: A peak power constraint is imposed on every transmitted codeword, and the average error probability of decoding the transmitted message is non-vanishing as the blocklength increases. It is well-known that the presenc...

A recently introduced fast algorithm for the computation of the first N terms in an expansion of an analytic function into ultraspherical polynomials consists of three steps: Firstly, each expansion coefficient is represented as a linear combination of derivatives; secondly, it is represented, using the Cauchy integral formula, as a contour integral of the function multiplied by a kernel; final...
