by means of he's homotopy perturbation method (hpm) an approximate solution of velocity eld is derived for the ow in straight pipes of non-newtonian uid obeying the sisko model. the nonlinear equations governing the ow in pipe are for- mulated and analyzed, using homotopy perturbation method due to he. furthermore, the obtained solutions for velocity eld is graphically sketched and compared w...

performance evaluation of universities is an important issue between researchers. classic data envelopment analysis (dea) models with deterministic data have been used by many authors to measure efficiency of universities in different countries. however, dea with stochastic data are, rarely used to measure efficiency of universities. in this paper, input oriented model in stochastic data envelo...

Stems, skins, seeds, and pulp are grape pomace (GP) components formed as by-products during wine production. The GP share represents about 25% of the total amount processed grapes, which is a significant organic waste (OW) that can be treated in composting process. purpose paper to consider possibility their use by presenting basic characteristics potentials other available fractions OW agricul...

The dramatic sea ice loss makes trans-Arctic navigation possible. However, navigability assessments at high temporal resolution are still very limited. To bridge this gap, daily concentration and thickness from CMIP6 projections applied to evaluate the future potential of Arctic shipping under multiple climate scenarios. September navigable area will continue increase through 2050s for open-wat...

Task-modality has been found to constrain the production of LREs in adults and children. However, there are no studies with young learners that have offered a comprehensive analysis LREs. To this end, paper will examine effect task-modality on features targeted them, as well their level engagement/elaboration during primary-school learners’ performance task containing both an oral written compo...

We prove the equidistribution of (weighted) periodic orbits geodesic ow on noncompact negatively curved manifolds toward equilibrium states in narrow topology, i.e. dual bounded continuous functions. deduce an exact asymptotic counting for (weighted or not), which was previously known only geometrically finite manifolds.

Dataaow analyses track the deenitions and uses of variable values, and are useful to optimizing and parallelizing compilers. Such analyses compute, for every (array cell) value read in a right-hand-side expression, the very operation which produced it. These analyses, however, make quite stringent hypotheses on the input programs: the control ow should be known at compile-time (i.e., static), a...

The eld of work ow technology has burgeoned in recent years providing a variety of means of automating business processes. It is a great source of opportunity for organisations seeking to streamline and optimise their operations. Despite these advantages however, the current generation of work ow technologies are subject to a variety of criticisms, in terms of their restricted view of what comp...
