Numerical and analytical studies of the onset of percolation in high-aspect-ratio fiber fiber systems such as nanotube reinforced polymers available in the literature have consistently modeled fibers as penetrable, straight, capped cylinders, also referred to as spherocylinders. In reality, however, fibers of very high-aspect ratio embedded in a polymer do not come into direct physical contact ...

Numerical simulations of soft-core frictionless disks in two dimensions are carried out to study behavior of a simple liquid as a function of thermal temperature T , packing fraction φ, and uniform applied shear strain rate γ̇. Inferring the hard-core limit from our soft-core results, we find that it depends on the two parameters φ and T/γ̇. T/γ̇ → 0 defines the athermal limit in which a shear dri...

Soft-core processors are being increasingly used in various embedded applications due to their flexibility, cost effectiveness and platform independence. It enables designers to modify the core designs with ease to achieve specific application goals. In this paper, the design of an enhanced soft-core processor based on OpenCores that is suited for telecommunication, multimedia and a variety of ...

Multifunctional materials with more than two good properties are widely required in modern industries. However, some properties are often trade-off with each other by single microstructural designation. For example, nanostructured materials have high strength, but low ductility and thermal stability. Here by means of spark plasma sintering (SPS) of nitrided Ti particles, we synthesized bulk cor...

In care activity or rescue activity, hands that can grasp creatures are sometimes needed. Therefore, it is considered that the soft mechanism that uses pneumatic elements is useful to realize such hands. In this paper, we propose a new type of soft actuator (Sponge-Core-Soft Rubber Actuator) in which a sponge rubber is covered with silicon rubber. The structure of the sponge rubber is divided i...

To overcome the problem of insufficient conformational sampling within biomolecular simulations, we have developed a novel Hamiltonian replica exchange molecular dynamics (H-REMD) scheme that uses soft-core interactions between those parts of the system that contribute most to high energy barriers. The advantage of this approach over other H-REMD schemes is the possibility to use a relatively s...

We study continuum percolation of three-dimensional randomly oriented soft-core polyhedra (prisms). The prisms are biaxial or triaxial and range in aspect ratio over six orders of magnitude. Results for prisms are compared with studies for ellipsoids, rods, ellipses, and polygons and differences are explained using the concept of the average excluded volume, . For large-shape anisotropie...

The jamming of bidisperse soft core disks is considered, using a variety of different protocols to produce the jammed state. In agreement with other works, we find that cooling and compression can lead to a broad range of jamming packing fractions ϕ{J}, depending on cooling rate and initial configuration; the larger the degree of big particle clustering in the initial configuration, the larger ...

We have implemented an FPGA soft-core, multithreaded, 64-bit MIPS R4000-style CPU called BERI to support research on the hardware/software interface. We have ported FreeBSD to this platform including support for multithreaded and soon multicore CPUs. This paper describes the process by which a BERI system boots from CPU startup through the boot loaders, hand off to the kernel, and enabling seco...

We present a simple density functional theory for the solid phases of systems of particles interacting via soft-core potentials. In particular, we apply the theory to particles interacting via repulsive point Yukawa and Gaussian pair potentials. We find qualitative agreement with the established phase diagrams for these systems. The theory is able to account for the bcc-fcc solid transitions of...
