Abstract This paper presents the developed software for processing parameter simulation and optimization of powder bed additive manufacturing by concentrated energy beams. The simulations are realized implementation a normalized diagram analytical model simulating heating layers moving linear heat source. Their is demonstrated electron beam or laser industrial alloys. provide useful reference m...

Let Φ be a simply-laced root system with simple roots ∆ = {αi : i ∈ I} embedded in the real vector space V with inner product 〈·,·〉. For convenience, we may assume that the roots have been normalized so that 〈α, α〉 = 2 for all α ∈ Φ. As a second convenience, we may assume that V has been enlarged, if necessary, so that 〈·,·〉 is nondegenerate on V . Now let σ be a diagram automorphism of (Φ,∆). ...

The phase diagram of a hard-disk system is studied by observing nonequilibrium relaxation functions of a bond-orientational order parameter using particle dynamics simulations. From a finite-time scaling analysis, two Kosterlitz-Thouless transitions can be observed when the density is increased from the isotropic fluid phase to closest packing. The transition densities are estimated to be 0.901...

This article discusses the properties of extremes of degree sequences calculated from network data. We introduce the notion of a normalized degree, in order to permit a comparison of degree sequences between networks with differing numbers of nodes. We model each normalized degree as a bounded continuous random variable, and determine the properties of the ordered k-maxima and minima of the nor...

We extend Knuth's 16 Boolean binary logic operators to fuzzy logic and neutrosophic logic binary operators. Then we generalize them to n-ary fuzzy logic and neutrosophic logic operators using the smarandache codification of the Venn diagram and a defined vector neutrosophic law. In such way, new operators in neutrosophic logic/set/probability are built. Introduction. For the beginning let’s con...

Background: Two main issues that challenge model building are number of Events Per Variable and multicollinearity among exploratory variables. Our aim is to review statistical methods that tackle these issues with emphasize on penalized Lasso regression model.  The present study aimed to explain problems of traditional regressions due to small sample size and m...

Many different devices and cycle arrangements can be used in part.ially cooling gas for helium liquefaction . With the exception of the Simon freeexpansion type liquefier , howeverwhich is suitable only for small-yield, batch productionall uch arrangements have a final stage at the lowest temperatures, in which a so-called Joule-Thomson proces takes place. This process may be considered to incl...

ABSTRACT The $P\dot{P}$ diagram is a cornerstone of pulsar research. It used in multiple ways for classifying the population, understanding evolutionary tracks, identifying issues our theoretical reach, and more. However, we have been looking at same plot more than five decades. A fresh appraisal may be healthy. Is $P \dot{P}$-diagram most useful or complete way to visualize pulsars know? Here ...
