The article considers the problem of segmenting interrelated terminals a transport network into fixed number relatively autonomous hubs when solving technical problems. There has been proposed most common and simple option for graph partition problems - by r-partitioning. Useful practical approaches to are studied. an assessing version developing segmentation procedures their content-richness. ...

The instructive structure-property relationships of ionic liquids (ILs) can be put to task-specific design of new functionalized ILs. The dicyanamide (DCA) ILs are typical CHN type ILs which are halogen free, chemical stable, low-viscous, and fuel-rich. The transport properties of DCA ionic liquids are significant for their applications as solvents, electrolytes, and hypergolic propellants. Thi...

a r t i c l e i n f o Geologists, physicists, and mathematicians have studied ripples and dunes for more than a century, but despite considerable effort, no general model has been proposed to explain perhaps the most fundamental property of their morphology: why are some bedforms straight, continuous, parallel, and uniform in planform geometry (i.e. two-dimensional) whereas others are irregular...

Abstract Transport measurements performed on a cross-sectional slice prepared from bulk GdBa 2 Cu 3 O 7- x -Ag single-grain superconductor of 25 mm in diameter are described and the results presented. The sample, which was fabricated via buffer-assisted top-seeded infiltration growth process, capable trapping maximum magnetic field ~ 1 T at 77 K. superconducting, RE-Ba-Cu-O [(RE)BCO] samples ge...

An asymptotic-induced scheme for nonstationary transport equations with the diffusion scaling is developed. The scheme works uniformly for all ranges of mean-free paths. It is based on the asymptotic analysis of the diffusion limit of the transport equation. A theoretical investigation of the behavior of the scheme in the diffusion limit is given and an approximation property is proven. Moreove...

We extend the normal transport model to include the medium effect on pions by treating them as quasiparticles. The property of the quasipion is determined using the delta-hole model. Modeling heavy-ion collisions at intermediate energies with the new transport equations, we find that it leads to an enhanced production of pions with low kinetic energies. This gives a plausible explanation for th...

objectives: herbal medicine is known as a valid alternative treatment. salvia reuterana, which has been used in the iranian traditional medicine, is mostly distributed in the central highlands of iran. salvia reuterana is a medicinal herb with various therapeutic usages. the aim of the present review is to take account of pharmacological properties of salvia reuterana. materials and methods: th...

In this paper we investigate the regularity of optimal transport maps for the squared distance cost on Riemannian manifolds. First of all, we provide some general necessary and sufficient conditions for a Riemannian manifold to satisfy the so-called Transport Continuity Property. Then, we show that on surfaces these conditions coincide. Finally, we give some regularity results on transport maps...

Between 1700 and 1870 Britain’s transport sector improved dramatically. This paper surveys the literature on Britain’s transport revolution and examines its contribution to economic growth during the Industrial Revolution. It reviews the important infrastructural and technological developments, documents the evolution of transport markets, and examines the developmental effects of transport. Th...
