According to turning instead of grinding process requirements and traditional working principle of ultrasonic vibration turning, a new idea of imitating grinding of two-dimensional ultrasonic vibration turning is brought firstly, and the mechanism of two-dimens ional ultrasonic vibration turning is elaborated. Based on the MATLAB software, grinding trajectory simulation and honing trajectory si...

We present a complete calculation of the Leading Order QCD corrections to the quark level decay amplitude for b → sγγ and study their relevance for both the inclusive branching ratio BR(B → Xsγγ) and for the exclusive decay channel Bs → γγ. In addition to the uncertainties in the short distance calculation, due to the choice of the renormalization scale, an appreciable uncertainty in both Bs → ...

Paraimmunity, as a reactive phenomenon of the host’s organism, induced by various heterogeneous antigens – due to some common antigenic components – appears alongside specific immunity. In bacterial and viral immunology paraimmunity is better known and studied than in parasitic immunology. It is known that, generally speaking, paraimmunity appears simultaneously with specific immunity, induced ...

The paper demonstrates reduced order modeling (ROM) of the strongly coupled system level dynamic analysis of micro electro mechanical systems (MEMS) by lumped finite elements (FE) and substructuring implemented in the ANSYS/Multiphysics program. Index terms Micro Electromechanical Systems (MEMS), Finite elements (FE), Coupled analysis, Reduced order modeling (ROM)

Measuring mechanical implications of high current densities in microelectronic packaging interconnects has always been a challenging goal. Due to small interconnect size this task has typically been accomplished by measuring the change in electrical resistance of the joint. This measurement parameter is global and does not give local mechanical state information. Also, understanding strain evol...

The aim of this paper is to present one type of pole assignment controller that is based on the analysis of optimal settings for the double integrator system. It takes into account parasitic delays in the control structure and constraints imposed on the control signal. The whole design is illustrated on two examples. Key-Words: Pole assignment control, constraints, saturation, double integrator...

The processes of lepton-nucleon scattering, including ones with both polarized beams, at high energy provide relevant information about interaction and particles structure, allowing to analyze nucleon spin structure. As energy and experimental accuracy rise, necessity to improve Born cross sections and polarized asymmetries with higher order radiative corrections becomes substantial. In this re...

In this paper we compare two models to compute the isostatic response of the Earths lithosphere to an external load. The lithosphere is modeled as a linear elastic solid. The two models differ in the mathematical formulation of the problem, their applicability in the incompressible limit, the choice of the finite elements used for discretization, and the solution strategy for the arising algebr...
