Tans-scale Coupling in Multi-scale Simulation
The physics and mathematics involved in modeling of components of cardiovascular system is very different from that in many other engineering problems. For example, the blood flows in vessels with a deformable boundary (the viscoelastic walls of the vessel) that may require modeling of fluid and tissue interaction and for smaller arteries, the non-Newtonian nature of the blood requires special ...
متن کاملFigurative Tours and Braids
We start with a rectangular grid of points, and we connect pairs of points to form either a tour (a Hamiltonian cycle) or a braid (a collection of disjoint paths that start in the top row and end on the bottom). In each case, our goal is to design a graph that will closely resemble a grayscale target image when viewed from a distance. From up close, the graph will look like an abstract pattern....
متن کاملDrifting and Tunneling
The drill & blast method is still the most typical method for medium to hard rock conditions. It can be applied to a wide range of rock conditions. Some of its features include versatile equipment, fast start-up and relatively low capital cost tied to the equipment. On the other hand, the cyclic nature of the drill & blast method requires good work site organization. Blast vibrations and noise ...
متن کاملHiking on the geriatrics rotation.
OBJECTIVES Most geriatrics training emphasizes chronically ill, dying, demented, or institutionalized patients. While some programs link trainees to healthy older adults in interview settings, we developed an experience that exposes trainees to vigorously active seniors with the objective of demonstrating the physical capabilities of older adults. METHODS We sent residents with a senior group...
متن کاملHiking the hypercube: producers and consumers
We study the dynamics of co-evolution of producers and customers described by bit-strings representing individual traits. Individual ”sizelike” properties are controlled by binary encounters which outcome depends upon a recognition process. Depending upon the parameter set-up, mutual selection of producers and customers results in different types of attractors, either an exclusive niches regime...
