The lattice Boltzmann method for multi-component immiscible fluids is applied to simulations of the behaviour of a drop in a square pipe flow for various Reynolds numbers of 10<Re<500, Weber numbers of 0<We<250 and viscosity ratios of η=1/5, 1, 2 and 5. It is found that, for low Weber numbers, the drop moves straight along a stable position on the diagonal line of the pipe section, and it moves...

We consider the symmetric rendezvous search game on a complete graph of n locations. In 1990, Anderson and Weber proposed a strategy in which, over successive blocks of n−1 steps, the players independently choose either to stay at their initial location or to tour the other n− 1 locations, with probabilities p and 1− p, respectively. Their strategy has been proved optimal for n = 2 with p = 1/2...

Sturge-Weber Syndrome (SWS) occurs sporadically with a frequency of approximately 1 in 50,000. SWS is a mesodermal phakomatosis. Klippel-Trenaunay Weber syndrome (KTWS) is another very rare phakomatosis. Overlap between SWS & KTWS is very rarely encountered. We report a 19 months old boy with features of both SWS and KTWS. The reported case had seizures, port wine haemangioma of the right side ...

In this paper, we show a procedure for solving multilevel fractional programming problems in a large hierarchical decentralized organization using fuzzy goal programming approach. In the proposed method, the tolerance membership functions for the fuzzily described numerator and denominator part of the objective functions of all levels as well as the control vectors of the higher level decision ...

This paper presents an application of interactive fuzzy goal programming to the nonlinear multi-objective reliability optimization problem considering system reliability and cost of the system as objective functions. As the decision maker always have an intention to produce highly reliable system with minimum cost, therefore, we introduce the interactive method to design a high productivity sys...

BACKGROUND Sturge-Weber syndrome is a congenital neurocutaneous disorder characterized by facial port-wine stain, leptomeningeal angioma, and neurological disorders. Sturge-Weber syndrome can coexist with other disorders in a few patients; however, muscular abnormalities have not been reported in patients with Sturge-Weber syndrome. CASE PRESENTATION A Chinese girl presented with extensive po...

This paper centers on the theoretical–methodological interconnections between Weber and the Austrian economists. First, the influence of classical Austrian economics, especially Menger and Böhm-Bawerk, on Weber is reexamined. Then we are concerned with the importance of Weber’s ideas in neoclassical Austrian economics, including Schumpeter, Mises and Hayek. Also, Weber’s legacy in modern econom...

The consideration of barriers to travel plays an increasingly important role in the transportation and location literature. In one of the classical papers on location problems with barriers, Katz and Cooper (1981) considered the Weber problem (often also referred to as median problem) with one circular barrier region. Considering the same problem we develop new structural results showing that t...

The paper introduces an alternative proof for Weber’s axiomatization of the random order values. In this proof we make use of a combinatorial result that has recently been discussed in Vasil’ev (2002). In addition, we provide a new and intuitive proof for this combinatorial result.
