the hot charging of continuously cast slabs steel is usually considered an effective method to reduce theenergy consumption in the hot rolling mills. in this work the application and optimizing of hot charging ofcontinuously cast slab in mobareke steel company has been investigated. mathematical relationship betweenthe cooling time of the stack of slabs and its mass average temperature is descr...

Abstmcl-Recently, various schemes have arisen to broadcast continuous media data such as audio and video. Some of them have f w d on reduciug clients' waiting time under the continuin condition, ia, to play data completely without any intemptions These schemes us0aUy employ multiple channels to broadcast continnous media data. However, receivers of many existing broadcast systems such as those ...

Many graphical objects can be represented by swept volumes (including its subset – generalised cylinders) by sweeping 2D or 3D templates along 3D trajectories. In this paper, we present a new approach for constructing swept volumes using image templates. We utilise scalar fields as our underlying data type, and employ volume ray casting techniques for rendering swept volumes in their original s...

introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...

Changes in arterial blood gases occurring during mechanical ventilation of a patient with extensive pulmonary disease have been presented. The Pa,,, and A-aDO, values observed in this patient demonstrate that various rea as of *,/Q imbalance exist simultaneously in the diseased lung. By altering the tidal volume and the pressure transmitted to the pulmonary capillary bed, the proportion of vari...

This paper is concerned with uniform large deviation principles of fractional stochastic reaction-diffusion equations driven by additive noise defined on unbounded domains where the solution operator non-compact and hence result [32] does not apply. The nonlinear drift assumed to be locally Lipschitz continnous instead being globally continuous. We first prove a principle for linear equation we...

A new opacity correction approach for oversampled volume ray casting is introduced. While the only existing opacity correction method in the literature is based on the assumption of dataset homogeneity, the new opacity correction method introduced in this paper is a faster, generalized voxel-by-voxel approach which does not assume dataset homogeneity. The new opacity correction avoids the datas...

Casting has many process variations depending upon the material, the type of pattern, mould and the pouring technique like sand casting, investment casting, die casting, squeeze casting and lost foam casting. Sand casting is the most widely used process which can be used to produce intricate parts in almost every metal that can be melted. Casting defects analysis is process of finding the root ...
