spinal cord injury (sci) is damage to spinal cord, which is categorized according to the extent of functional loss, sensation loss and inability of the subjects to stand and walk. the patients use two transportation systems including orthosis and wheelchair. it was claimed that standing and walking bring some benefits such as decreasing bone osteoporosis, prevention of pressure sores, and impro...

We propose two new greedy algorithms to be used by software clients running the BitTorrent peer to peer protocol: a new peer selection algorithm and a new piece selection algorithm. We provide experimental results showing that the proposed algorithms are better than the ones currently in use. When used together in our experiments, the algorithms decreased the expected download time by ??% on av...

In the past few years there has been a considerable amount of growth in the Web of Linked Data. A large amount of the information available on the web is in the unstructured form. With the increase in the number of data resources, linking such heterogeneous resources has now become a challenge. Even though, there are many automatic tools available to interlink heterogeneous data sources, the li...

The Lempel-Ziv-Welch (LZW) compression algorithm is widely used because it achieves an excellent compromise between compression performance and speed of execution. A simple way to improve the compression without significantly degrading its speed is proposed, and experimental data shows that it works in practice. Even better results are achieved with an additional optimization of “phasing in” bi...

In partnership with 30 colleges and universities, the National Center for Academic Transformation (NCAT) has proven that it is possible to improve quality and reduce cost in higher education. Course redesign using information technology is key. Primary Findings  Twenty-five of the 30 projects showed a significant increase in student learning. (The other five showed learning equivalent to tradi...

We consider teleoperation in which a slave manipulator, seen in one or more video images, is controlled by moving a master manipulandum. The operator must mentally transform (i.e. rotate, translate, scale, and/or deform) the desired motion of the slave image to determine the required motion at the master. Our goal is to make these mental transformations less taxing in order to decrease operator...

Paragraph vectors were proposed as a powerful unsupervised method of learning representations of arbitrary lengths of text. Although paragraph vectors had the advantage of being versatile, being unsupervised and unconstrained by lengths of text, the concept has not been further developed since its first publication. We propose two extensions upon the initial formulation of the paragraph vector,...

context hemorrhoidal disease is the most common anorectal disorder that requires surgical intervention. hemorrhoids require treatment when they result in symptoms such as bleeding or prolapse. surgical intervention is indicated for significant prolapse, and a number of accepted and viable methods are available for treating prolapsing hemorrhoids that do not reduce spontaneously (grade iii and i...
