Thermal flow phenomena in a double lid–driven enclosure have many potential applications numerous engineering domains. The present article theoretically investigates the heat transfer analysis of power-law fluid hexagonal cavity embedded with square obstacle. upper and lower lid walls are considered heated along centered square, while rest thermally insulated. In addition, horizontal uniformly ...

Thus far, simulations have failed to predict accurately electrostatic powder charging during pneumatic transport. We advanced the modeling of flow by a three-part study: first, we shot individual particles on metal target and measured exchanged charge. Second, based these results, formulated an empirical model implemented it in our CFD tool. Using this tool, performed large-eddy through square ...

Note that the main lemma used in the proof of Theorem 2 is Lemma 7 below, and the other lemmas are used as auxiliary geometric lemmas. For completeness , we include in this document a figure of the Promenade motion-planning problem, as it appears in the main text. q1 q2 A1 A2 B1 B2 α α 1 Fig. 1: An illustration of the Promenade motion planning problem, a square obstacle within a square bounding...

In this paper, we present efficient algorithms for updating the labeling of a set of n points after the presence of a random obstacle that appears on the map repeatedly. We update the labeling so that the given obstacle does not appear in any of the labels, the new labeling is valid, and the labels are as large as possible (called the optimal labeling). Each point is assumed to have an axis-par...

introduction. regarding the role of research in developing and improving a better culture, society and economics, 95% to 97% world finance in research belongs to developed countries while only 3%-5% to developing countries. although the universities as the major organizations are to do research works, it seems that there are some problems to bring this true. we tried to find out if a load of te...

A major obstacle to using superconducting quantum interference devices (SQUIDs) as qubits is flux noise. We propose that the heretofore mysterious spins producing flux noise could be O_{2} molecules adsorbed on the surface. Using density functional theory calculations, we find that an O_{2} molecule adsorbed on an α-alumina surface has a magnetic moment of ~1.8 μ_{B}. The spin is oriented perpe...

The goal is to collect pearls (small golden circles) by sliding a droplet of water (large blue circle) over them in a grid map. The map contains obstacles (square blocks). In each move, the droplet slides in one of the four directions to the maximal extent, until it is stopped by an obstacle. 7 Moves! left (1st pearl) up, left (2nd pearl) down, right, up, left (3rd pearl) The map contains only ...
