Entropy generation is always a matter of concern in heat transfer system. It denotes the amount energy lost as result irreversibility. As result, it must be reduced. The present work considers an investigation on turbulent forced convective and entropy Al2O3-Ethylene glycol (EG) nanofluid inside circular tube subjected to constant wall temperature. study focused development analytical framework...

There is a long tradition in economics about the question of whether intergenerational discounting is fair or not. Ramsey (1928) was the first economist that criticized the discounting and mentioned that the just rate of discounting is zero.  In this paper it was tried to calculate the just rate of discounting for Iran with respect to Islamic thoughts. According to Islam, intergenerational just...

For a general class of hyperbolic-parabolic systems including the compressible NavierStokes and compressible MHD equations, we prove existence and stability of noncharacteristic viscous boundary layers for a variety of boundary conditions including classical Navier-Stokes boundary conditions. Our first main result, using the abstract framework established by the authors in the companion work [G...

Aiming to unify known results about clustering mixtures of distributions under separation conditions, Kumar and Kannan [KK10] introduced a deterministic condition for clustering datasets. They showed that this single deterministic condition encompasses many previously studied clustering assumptions. More specifically, their proximity condition requires that in the target k-clustering, the proje...

Fault detection techniques based on vibration measurement are implemented to identify in an early stage failures appearing gear transmissions. Condition monitoring indicators (CMI), like: Root Mean Square (RMS), Crest Factor, Kurtosis, FMO, FM4, Energy ratio, operator, NA4 or NB4, used estimate the level of faults such as pitting, cracks, spalling, scuffing scoring. However, is multitude indica...

Temporal uncertainty in raw data can impede the inference of temporal and causal relationships between events and compromise the output of data-to-text NLG systems. In this paper, we introduce a framework to reason with and represent temporal uncertainty from the raw data to the generated text, in order to provide a faithful picture to the user of a particular situation. The model is grounded i...

A fast adaptive algorithm for the solution of elliptic partial diierential equations is presented. It is applied here to the Poisson equation with periodic boundary conditions. The extension to more complicated equations and boundary conditions is outlined. The purpose is to develop algorithms requiring a number of operations proportional to the number of signiicant coeecients in the representa...
