A general-purpose automatic hexahedral mesh generation system for FEA (Finite Element Analysis) was developed based on a shape recognition technique and the boundary-fit method. In this system, a solid model is analyzed and decomposed into single-connected sub-models. Then, other sub-models topologically identical to the original ones are constructed using only orthogonal angles. Cubes are used...

We examine the applicability of perturbative QCD to B meson decays into D mesons. We find that the perturbative QCD formalism, which includes Sudakov effects at intermediate energy scales, is applicable to the semi-leptonic decay B → Dlν, when the D meson recoils fast. Following this conclusion, we analyze the two-body non-leptonic decays B → Dπ and B → DD s. By comparing our predictions with e...

We report the draft genome sequences of three vancomycin-susceptible methicillin-resistant Staphylococcus aureus strains. S. aureus strain MV8 is a sequence type 8 (ST-8) staphylococcal cassette chromosome mec element type IV (SCCmec IV) derivative, while the other two strains (S. aureus MM25 and MM61) are ST-5 SCCmec II strains. MM61 is also closely related to the heterogeneous vancomycin-inte...

The element connectivity problem falls in the category of survivable network design problems { it is intermediate to the versions that ask for edge-disjoint and vertex-disjoint paths. The edge version is by now well understood from the viewpoint of approximation algorithms, but very little is known about the vertex version. Our problem, which is interesting in its own right, should shed light o...

This paper is concerned with a common element of the set of fixed point for an asymptotically pseudocontractive mapping in the intermediate sense and the set of solutions of the mixed equilibrium problems in Hilbert spaces. The strong convergence theorem for the above two sets is obtained by a general iterative scheme based on the shrinking projection method, which extends and improves that of ...

Abstract—In this study, the thermoelastic instability (TEI) was analyzed using the finite element analysis technique. The governing dynamic and heat equations were described. Three dimensional thermomechanical analysis model of the disc brake system were created. An intermediate processor based on the staggered approached was used to exchange result data: temperature, friction contact power, no...

We outline a solution method for mixed finite element discretizations based on dissecting the problem into three separate steps. The first handles the inhomogeneous constraint, the second solves the flux variable from the homogeneous problem, whereas the third step, adjoint to the first, finally gives the Lagrangian multiplier. We concentrate on aspects involved in the first and third step main...

Van Herk has shown that the erosion/dilation operator with a linear structuring element of an arbitrary length can be implemented in only 3 min/max operations per pixel. In this paper, the algorithm is generalized to erosions and dilations along discrete lines at arbitrary angles. We also address the padding problem; so that the operation can be performed in place without copying the pixels to ...

We prove a Weyl Harish-Chandra integration formula for the action of a reductive dual pair on the corresponding symplectic space W. As an intermediate step, we introduce a notion of a Cartan subspace and a notion of an almost semisimple element in the symplectic space W. We prove that the almost semisimple elements are dense in W. Finally, we provide estimates for the orbital integrals associat...

We study the mass, width and couplings of the lightest vector multiplet. Effective field theories based on chiral symmetry and a 1/NC counting are adopted in order to describe the vector form factor associated to the two-pseudoscalar matrix element of the QCD vector current. The bare poles of the intermediate s–channel resonances are regularized through a Dyson-Schwinger-like summation. This pr...
