We consider a mixed finite element method for the Stokes problem in a polygonal domain Q cz U An inf-sup condition is established which fits into the abstract jramework oj Babuska and Brezzi Using hnear finite éléments, we obtain O{h*)-error estimâtes for the energy norm of the velocity and the L-norm of the pressure The exponent a only dépends on thegreatest intenor angle at a corner of Cl and...

BACKGROUND Coronary hemodynamics and physiology specific for bifurcation lesions was not well understood. To investigate the influence of the bifurcation angle on the intracoronary hemodynamics of side branch (SB) lesions computational fluid dynamics simulations were performed. METHODS A parametric model representing a left anterior descending-first diagonal coronary bifurcation lesion was cr...

An association between lateral patellar dislocation (LPD) and medial collateral ligament injury (MCL) has recently been demonstrated on MRI. The same valgus injury that disrupts the femoral MCL insertion can also cause a simultaneous MPFL tear at its femoral insertion, due to the close anatomical relationship of both ligamentous structures. Valgus laxity due to MCL-deficiency increases the Q-an...

We have applied Q-learning method so that a mobile robot acquire a shooting behavior of a soccer game. Thought the acquired behavior is tested in RoboCup-97, the performance is limited because of the narrow visual angle of the robot. Therefore, we install an omnidirectional vision into a mobile robot to enlarge a visual angle and apply Q-learning to behavior acquisition of the robot. An attenti...

The Qweak experiment at Jefferson Lab aims to make a 4% measurement of the parity-violating asymmetry in elastic scattering at very low Q of a longitudinally polarized electron beam on a proton target. The experiment will measure the weak charge of the proton, and thus the weak mixing angle at low energy scale, providing a precision test of the Standard Model. Since the value of the weak mixing...

To investigate the effect of blade wrap angle on hydrodynamic radial force a single centrifugal pump, numerical simulation is conducted pumps with different angles. The external characteristics and pump was analyzed according to result. It found that, increase angle, head efficiency are improved, H-Q curve becomes steeper, also increased gradually, while high-efficiency area narrowed. has great...

The turbulent energy equation, together with a modified mixing length, is adopted to close the governing equations in the turbulent planetary boundary layer under stratification conditions. The system of governing equations is decoupled by introducing a stratification parameter, Q. Numerical integration of the system, in general, is outlined and should be easily implemented. Results for the mom...

Exclusive electroproduction of ρ mesons has been measured using the ZEUS detector at HERA in two Q ranges, 0.25 < Q < 0.85 GeV and 3 < Q < 30 GeV. The low-Q data span the range 20 < W < 90 GeV; the high-Q data cover the 40 < W < 120 GeV interval. Both samples extend up to four-momentum transfers of |t| = 0.6 GeV. The distribution in the azimuthal angle between the positron scattering plane and ...

This paper presents an investigation on mechanism of the inclined 1 cone penetration test (CPT) using the numerical discrete element method (DEM). 2 A series of penetration tests with the penetrometer inclined at different angles 3 (i.e., 0°,15°, 30°, 45° and 60°) were numerically performed under µ=0.0 and 4 µ=0.5, where µ is the frictional coefficient between the penetrometer and the soil. 5 T...
