A multicomponent lattice Boltzmann scheme is used to investigate the surface coating of substrates with two topographical features by a gravity-driven thin liquid film. The considered topographies are U- and V-shaped grooves and mounds. For the case of substrates with two grooves, our results indicate that for each of the grooves there is a critical width such that if the groove width is larger...

Electromigration versus line width in the 0.12–10 lm range and the configuration of the via/line contact in dual damascene Cu has been investigated. There are two scenarios for width scaling impact on electromigration. One is the width < 1 lm region, in which the MTF shows a weak width dependence, except for the via-limited condition. The other is the width > 1 lm region, in which the MTF shows...

in this paper, buckling of simply supported column with an edge crack is investigated numerically and analytically. four different scenarios of damage severities are applied to a column, open crack assumption and the effect of closing crack in stability of the column which depends on position and size of cracks, are numerically compared. crack surfaces contact is modeled with gap element using ...

Gravity-induced sagging can amplify variations in goniometric measurements of the contact angles of sessile drops on super-liquid-repellent surfaces. The very large value of the effective contact angle leads to increased optical noise in the drop profile near the solid-liquid free surface and the progressive failure of simple geometric approximations. We demonstrate a systematic approach to det...

PURPOSE Imperfect spacing between the primary incisors and mal-alignment of the permanent incisors may suggest the need for orthodontic intervention. Without sufficient data, decisions to treat are based on individual judgment rather than evidence. The present study was undertaken to determine whether slipped contact arrangement (distal-lingual surface of mandibular permanent lateral incisors o...

Surface tension effects can dominate multi-phase flows when the length scales of the problem are small. The resulting Capillary forces at a phase interface between two immiscible fluids are proportional to the local curvature of the flow and try to minimize the interfacial area. A more complex situation occurs when three phases are in contact or when two phases are in contact with a wall. The s...

electrical, structural and morphological properties of ni silicide films formed in ni(pt 4at.% )/si(100) and ni0.6si0.4(pt4at.% )/si(100) structures at various annealing temperatures ranging from 200 to 1000 oc were studied. the ni(pt) and ni0.6si0.4(pt) films with thickness of 15 and 25 nm were deposited by rf magnetron co-sputtering method, respectively.  the annealing process of the structur...

OBJECTIVE To observe the accuracy of femoral preparation and the position of the cementless prosthesis in femoral cavity, and to compare the results between the computer-assisted surgical group (CASPAR) and the conventional group. METHODS Ten femoral components were implanted either manually or by CASPAR in cadaver femurs. The specimens were cut to 3 mm thick slices. Microradiograms of every ...
