this work presents thermoplastic analysis of fg rotating diskswith variable thickness and constant angular velocity. the solutions are obtained by variable material property (vmp) theory. in this theory, the domain is divided into some finite sub-domains in the radial direction, in which the properties are assumed to be constant and the form of the elastic response is used to solve elastic-plas...

determination of price of lost property is faced with two difficulties: on the one hand, property price is variable from time to time so it is necessary to determine the price of the item in which time must be considered? on the other side question of devaluation of money is raised. whether the agent of the loss is responsible for this or she/he is merely responsible for the value of property i...

The present numerical work deals with the optimization of micro-channel heat sink using irreversibility analysis. nanofluid Al2O3-water different nanoparticles concentration and temperature-dependent property is chosen as a coolant. flow considered fully developed, steady, laminar in constant cross-section circular channels. Navier-Stokes energy equations are solved for single-phase total mass ...

This paper presents a machine learning methodology to improve the predictions of traditional RANS turbulence models in channel flows subject strong variations their thermophysical properties. The developed formulation contains several improvements over existing Field Inversion Machine Learning (FIML) frameworks described literature. We first showcase use efficient optimization routines automati...

Variable selection for multivariate nonparametric regression is an important, yet challenging, problem due, in part, to the infinite dimensionality of the function space. An ideal selection procedure should be automatic, stable, easy to use, and have desirable asymptotic properties. In particular, we define a selection procedure to be nonparametric oracle (np-oracle) if it consistently selects ...

We study the notion of H-dimension and the formally stronger kvariable property, as considered by Gabbay and Immerman & Kozen. We exhibit a class of flows of time that has H-dimension 3, and admits a finite expressively complete set of one-dimensional connectives, but does not have the k-variable property for any finite k.
