Miscanthus is emerging as a promising feedstock for domestic biofuel production. However, inefficiencies of the machinery that is used for harvesting bioenergy crops such as miscanthus currently prohibit commercial production. The performance of a mower-conditioner used to harvest miscanthus was evaluated, and modifications to the disk head were made to allow the machine to operate more efficie...

The use of distributional semantics to represent the meaning of a single word has proven to be very effective, but there still is difficulty representing the meaning of larger constituents, such as a noun phrase. In general, it is unclear how to find a representation of phrases that preserves syntactic distinctions and the relationship between a compound’s constituents. This paper is an attempt...

We can outperform the most powerful disk spin-down algorithm available by using a small non-volatile storage write-only cache to temporarily store hard disk write requests while a disk is spun-down. In our experiments, we use a USB thumb drive device as our non-volatile storage cache. By redirecting writes to a flash memory while a disk is spun-down we avoid costly hard disk cycle start-stop op...

The unsteady flow of a Newtonian fluid produced by a sudden coincidence of the axes of a porous disk and the fluid at infinity has been investigated while they are initially rotating with the same angular velocity about non-coincident axes. The exact solutions of both the velocity field and the components of shear stress on the disk have been obtained with the use of the Laplace transform techn...

We analyze the relationship between the mass of a spherical component and the minimum possible thickness of stable stellar disks. This relationship for real galaxies allows the lower limit on the dark halo mass to be estimated (the thinner the stable stellar disk is, the more massive the dark halo must be). In our analysis, we use both theoretical relations and numerical N-body simulations of t...

The technique of laser micro-processing has recently found several important and widespread applications in the manufacturing of disk-drive components. Examples provided here include the cleaning of surface contaminants, the formation of “nano-bumps” on disk surfaces for controlled surface texturing or for making nanometer-height standards, and the micro-bending of magnetic head sliders for fli...

Simulation and modeling are useful tools in prototyping advances in many areas of technology. The performance of modern processors advances much faster than that of storage components making disk systems prime candidates for simulation. Simulating disk systems allows researchers to determine and quantify the performance impact of alternative file system designs and disk data rearrangement techn...
