This paper demonstrates particle tracking velocimetry performed for a model system wherein particle-laden liquid metal flow about cylindrical obstacle was studied. We present the image processing methodology developed detection in images with disparate and often low signal- contrast-to-noise ratios, application of our MHT-X tracing algorithm trajectory reconstruction within wake obstacle. Preli...

The neutron charge form factor G En (q) is determined from an analysis of the deuteron quadrupole form factor F C2 (q) data. Recent calculations, based on a variety of different model interactions and currents, indicate that the contributions associated with the uncertain two-body operators of shorter range are relatively small for F C2 (q), even at large momentum transfer q. Hence, G En (q) ca...

dand f -shells support a large number of local degrees of freedom: dipoles, quadrupoles, octupoles, hexadecapoles, etc. Usually, the ordering of any multipole component leaves the system sufficiently symmetrical to allow a second symmetry breaking transition. To classify the possibilities, one has to construct the symmetry group of the first ordered phase, and then re-classify the order paramet...

We present ab initio calculations of both the dipole and quadrupole polarizabilities within the framework of the relativistic coupled-cluster theory. We directly solve the first order perturbed equation arising from a general one-electron perturbation, thereby avoiding an explicit summation over intermediate states. This method can be applied to a wide range of problems including the high preci...

We present the analysis on the quadrupole phases of the Internal Linear Combination map, ILC(I) and (III) derived by the WMAP team (1 and 3-year data release). This approach allows us to see the global trend of non-Gaussianity of the quadrupoles for the ILC(III) map through phase correlations with the foregrounds. Significant phase correlations is found in between the ILC(III) quadrupole and th...

Predictions of electrostatic double-layer interaction forces between two similarly charged spherical colloidal particles inside an infinitely long "rough" capillary are presented. A simple model of a rough cylindrical surface is proposed, which assumes the capillary wall to be a periodic function of axial position. The periodic roughness of the wall is characterized by the wavelength and amplit...

Emulsion or suspension destabilisation often results from coalescence or particle aggregation (flocculation) leading to particle migration (creaming or sedimentation). Creaming and sedimentation are often considered as reversible, while coalescence and flocculation spell disaster for the formulator. Thus, it is of prime importance to detect coalescence or cluster formation at an early stage to ...

Electrokinetics-induced motion and deformation of a hyperelastic particle confined in a slit microchannel has been numerically investigated for the first time with a full consideration of the fluid-particle-electric field interactions and the dielectrophoretic (DEP) effect. When the initial orientation of a cylindrical particle with respect to the applied electric field, θ(p0), is 90°, the part...
