classical trajectory (monte carlo) calculation is used to calculate collision rate constants of ion-quadrupolar molecule interactions for the h¯+c2h2 system. the method presented here takes into account the effect of the induced dipole-induced dipole potential on ion-quadrupolar molecule collision rate constants. it is also assumed that the colliding particles have a definite size. the thermal ...

this paper focuses on the optimization of initiating dimensions of groove bearing in association with de- sired design of vehicle’s front structure which is made up of low carbon steels in the case of frontal collision. axial bearing analysis is done numerically using nonlinear finite element code ls-dyna. in this analysis, changes of two main parameters including measure of energy absorption o...

in this research, the effect of bubble surface area flux, sb, and particle size on flotation rate constant, k, of pyrite (fes2) particles was studied using bubble-particle interactions. the bubble-particle collision, attachment and detachment efficiencies were calculated under different flow regimes. the k increased with increase in the collision efficiency and decrease in the detachment effici...

(a) standard axial, (b) standard oblique showing overwhelming distortion from oblique voxel alignment, (c) oblique ISEE as acquired with axial acquisition showing anterior and posterior aliased portions, (d) same ISEE data set as (c) after reformatting into oblique plane. In (c) oblique ISEE provide...

AbstructOblique projection operators are used to project measurements onto a low-rank subspace along a direction that is oblique to the subspace. They may be used to enhance signals while nulling interferences. In this paper, we give several basic results for oblique projections, including formulas for constructing oblique projections with desired range and null space. We analyze the algebra an...

purpose: to determine the effect of recession and myectomy on inferior oblique overaction (iooa). method: this study was performed on 50 patients (82 eyes) scheduled for iooa surgery who were randomly divided into two groups: recession (r) versus myectomy (m). a complete eye examination was performed before the operation. io was cut off at its inferior temporal region when using m procedure. in...

Traditional superior oblique weakening procedures may be unpredictable and lead to superior oblique underaction. The use of 240 retinal band as a spacer to lengthen the superior oblique tendon has been proposed as a more controlled approach than superior oblique tenotomy and related procedures. The use of this technique is reported in a patient with diplopia following an orbital floor blow out ...

We study two-dimensional (2D) isotropic quantum droplets (QDs) in dipolar binary Bose–Einstein condensates (BECs). The QDs are supported by the competition between 2D form of Lee-Huang-Yang (LHY) term and dipole-dipole interactions (DDIs). Moreover, DDIs plane can be tuned to either repulsive or attractive. Before that, BECs were often explored three-dimensional (3D) systems, with attractive LH...
