Virtual Manufacturing is a concept of executing manufacturing processes in computer environment as well as in the real word. This paper deals with the NC programming verification processes. It describes the main levels of simulation tasks. The second part of this paper focuses on the object oriented modelling and simulation architecture for simulation of NC machining operation. In this area som...

The purpose of natural cognitive systems appears to be to allow the organism to respond more rapidly to it’s environment and thus survive. This is achieved in two ways. First there are reflexes, the built-in actions an organism will take to stimulus. The second is the prediction of what the future state of the immediate environment will be and thus avoid harmful situations. The greater the inte...

‎Let $tau$ be a subgroup functor and $H$ a $p$-subgroup of a finite group $G$‎. ‎Let $bar{G}=G/H_{G}$ and $bar{H}=H/H_{G}$‎. ‎We say that $H$ is $Phi$-$tau$-quasinormal in $G$ if for some $S$-quasinormal subgroup $bar{T}$ of $bar{G}$ and some $tau$-subgroup $bar{S}$ of $bar{G}$ contained in $bar{H}$‎, ‎$bar{H}bar{T}$ is $S$-quasinormal in $bar{G}$ and $bar{H}capbar{T}leq bar{S}Phi(bar{H})$‎. ‎I...

background: the present study aimed to investigate the nailfold capillaroscopy (nc) features of the patients with dermatomyositis (dm) and its correlation with their disease activity indices, physical findings, and laboratory results. methods: the present cross-sectional study was conducted on 27 dm patients above 16 years old who had referred to an(there are 3 clinics not one) outpatient rheum...

the goal of this study was to investigate the common clinical chemistry and distribution of xanthine oxidase (xo) in selected tissues of a mouse model of menopause. twenty four nmri female mice were divided into three groups: normal control (nc), and ovariectomized (ovx) groups and an estrogen-treated ovariectomized (ovx+e) group which received subcutaneous injection of estradiol benzoate (2 mg...

BACKGROUND Although the increased risk for perinatal morbidity and mortality of babies born after ART is largely attributed to a higher rate of multiple gestations, a significantly worse perinatal outcome for singleton pregnancies following ART compared to pregnancies after natural conception has been reported as well. Most studies only include IVF/ICSI pregnancies; studies describing the perin...

On the basis of the topological l/Nc expansion, various types of the distribution function for the soft and the hard processes are obtained, which contain the freedoms pertaining to the underlying string structure of hadronic reactions. It is stressed that the distribution functions for the soft process refer to the energy fractions of jets and are distinct from those for the hard process in th...
