The ability to migrate a virtual machine (VM) from one physical host to another is important in a number of cases such as power management, on-line maintenance, and load-balancing. The amount of memory used in VMs have been steadily increasing up to several gigabytes. Consequently, the time to migrate machines, the total migration time, has been increasing. The aim of this thesis is to reduce t...

The topography of the Giardia trophozoite is dominated by the large domed sucking disk of the ventral surface. Attached to the host duodenal epithelium, the rim of this disk penetrates the enteric surface coat and interdigitates with microvilli of the epithelial cells, approaching to within 20 nm of the host surface membrane. Distortion of the host brush border within the disk suggests an appli...

In the 1970s, the standard accretion disk models were constructed to largely explain observations from the binary systems. In these systems, angular momentum supplied at the outer edge is necessarily Keplerian. Viscosity drives the inflow by removing angular momentum outwards and keeping the entire disk Keplerian in the process. Since then these binary disk models are being used also to explain...

This article’s model based diagnostics system has four modules. Diagnosis and fault location forms physics models of the machine, measures states off the real in-service machine, generates simulated machine states and simulated sensor outputs for the machine model with loads same as the real machine, and compares simulated sensor outputs to real sensor outputs. The parameter tuning module adjus...

In this study, the full dynamic reactions in bearing supports of leading wheel big band saw machines are determined. These caused by both external loads and kinematic mass characteristics rotating disk. Expressions for calculating forces moments that occur operating mode obtained. The influence disk is studied expressions these load With help expressions, parameters machine can be selected such...

We present new evidence, based on faint HST proper-motions, for a bi-modal kinematic population of old white dwarfs, representative of the Thick-Disk and Halo of our Galaxy. This evidence supports the idea of a massive Halo comprised of faint and old white dwarfs, along with an extant population of Thick-Disk white dwarfs. We show how most of the required dark matter in the solar vicinity can b...

A detailed study of nearby, morphologically normal Sa galaxies reveals that about half show some spectrocopic evidence for kinematically distinct components despite their undisturbed optical appearance. In eight of nine objects mapped in the 21 cm HI line, the HI distribution extends far outside the optical disk and warps of the HI disk are complex. The multiwavelength evidence can be interpret...

We present a very simple, free tool for parallelizing calculations under Matlab in multicore and cluster environments. After the installation it does not use any compilers, MEX files, disk files, etc. It is compatible with the old Paralize package, but allows the involved cores/machines to do other jobs when a worker core/machine is not busy.

A holographic optical element (HOE) is a kind of diffractive optical element. It can replace an optical system with multiple optical components such as lenses, mirrors, beamsplitters, and prisms. Thus, it is expected to be possible improve performance and reduce the number of optical parts of various optical systems, such as optical storage systems 1) like compact disk or digital versatile disk...
