The twin-screw compressor is constantly attaJ.ninq hiqher performance due to new rotor profiles, new rotor manufacturing technology and new designs. Besides this, new refrigerants as well as new lubricants can be expected on the market. Therefore there is always a need to update performance data. To m1nimize the number of test points and still receive representative data, there 1s a need of an ...

This paper is a phenomenological study representing the influence of hardening type on instrumented indentation F-h curve. Spherical and inverse analysis techniques (IAT) are used two metallic materials (DP600 AA2017) investigated. Pure isotropic (Voce) combined (Chaboche 1986) laws adopted for describing plastic behavior studied materials. The loading curve first. Kinematic results in softenin...

We investigate the problem of constructing spatial C 2 closed loops from a single polynomial curve segment r ( t ) , ? [ 0 1 ] with prescribed arc length S and continuity Frenet frame curvature at juncture point = . Adopting canonical coordinates to fix initial/final tangent, closed-form solution for two-parameter family interpolants given data can be constructed in terms degree 7 Pythagorean-h...

Background: Gestational diabetes mellitus (GDM) is one of the most common metabolic disorders in pregnancy, which is associated with serious complications. In the event of early diagnosis of this disease, some of the maternal and fetal complications can be prevented. The aim of this study was to early predict gestational diabetes mellitus by two statistical models including artificial neural ne...

Using the loop equations we find an explicit expression for genus 1 correction in hermitian two-matrix model in terms of holomorphic objects associated to spectral curve arising in large N limit. Our result generalises known expression for F 1 in hermitian one-matrix model. We discuss the relationship between F 1 , Bergmann tau-function on Hurwitz spaces, G-function of Frobenius manifolds and d...

In this paper we consider D = 4 NCSYM theories with 8 supercharges. We study these theories through a proper type IIA (and M-theory) brane configuration. We find the one loop beta function of these theories and show that there is an elliptic curve describing the moduli space of the theory, which is in principle the same as the curve for the commutative counterpart of our theory. We study some o...
