This paper analyzes the effect of turbulence on the performance of an inverted threelobe pressure dam bearing which is produced by incorporating a pressure dam in the upper lobe and two relief tracks in the lower two lobes of an ordinary inverted threelobe bearing. For analysis purpose different values (0, 1500, 3000, and 6000) of Reynolds number are considered to study the effect of turbulence...

The three-dimensional instability of the thermocapillary convection in cylindrical undeformable floating zones heated laterally is studied numerically. Different types of the boundary conditions, including radiation heating, linearized radiation and prescribed heat flux are used in the calculation. Stability diagrams showing the Prandtl number dependence of the critical Marangoni numbers that r...

We define cut-and-join operator in Hurwitz theory for merging of two branching points of arbitrary type. These operators have two alternative descriptions: (i) they have the GL characters as eigenfunctions and the symmetric-group characters as eigenvalues; (ii) they can be represented as differential operators of the W -type (in particular, acting on the time-variables in the HurwitzKontsevich ...

Abstract: This paper studies a continuous Bertrand duopoly game model with two-stage delay. Our aim is to investigate the influence of delay and weight on the complex dynamic characteristics of the system. We obtain the bifurcation point of the system respect to delay parameter by calculating. In addition, the dynamic properties of the system are simulated by power spectrum, attractor, bifurcat...

Collective instabilities are a potential limiting factor for the performance of the FAIR rings at GSI Darmstadt. Here, we discuss results of numerical investigations for SIS 100 and for the SIS 18 Upgrade together with experimental investigations in the SIS 18 synchrotron. Within our experimental investigations, the first measurement of the transverse Beam Transfer Function (BTF) in SIS 18 were...

growth of the prostate gland, also development of benign prostatic hyperplasia (BPH) is an androgen-dependent functions. Testosterone plays a major role in the prostate gland. Rat prostate gland is one of the most widely used models of animals in investigation. The rat prostate gland consisted of five lobes; the ventral, anterior, dorsal, lateral type 1 and latteral type 2. The goal of present ...

A scheme for systematically achieving accurate numerical evaluation of multi-loop Feynman diagrams is developed. This shows the feasibility of a project aimed to produce a complete calculation for two-loop predictions in the Standard Model. As a first step an algorithm, proposed by F. V. Tkachov and based on the so-called generalized Bernstein functional relation, is applied to one-loop multi-l...

We present a calculation of interference effects in Hjj production via gluon fusion and via vector boson fusion, respectively, beyond tree level. We reproduce results recently discussed in the literature, but go beyond this calculation by including a class of diagrams not considered previously. Special care is taken in developing a numerically stable and flexible parton level Monte-Carlo progra...
