We study an online problem in which a set of mobile servers have to be moved in order to efficiently serve a set of requests that arrive in an online fashion. More formally, there is a set of n nodes and a set of k mobile servers that are placed at some of the nodes. Each node can potentially host several servers and the servers can be moved between the nodes. There are requests 1, 2, . . . tha...

were uniform and roundish with visible pulsation. On palpation the skin was freely movable over them, and the pulsation was found to be expansile. Pulsation was practically abolished by pressure of the superficial temporal artery over the zygoma. On keeping up this pressure and again palpating, it was found that the sacs could not be emptied, were resistant to pressure, and fairly freely movabl...

Suppose that you are sitting at the writing table. In front of you there are books, text-books, pens, pencils, pieces of paper with some short notes, and a lot of other things. You need to do something, you have to organize your working place, and for this you will start moving the things around the table. There are no restrictions on moving all these things and there are no regulations on how ...

In this paper, we propose a hand-held mobile projection system that can freely project keystone free content on a general flat surface without any markings. Such a projection system can give the user great freedom of control of the display such as viewing angle and distance without suffering from distortion. We attach a camera to the projector to form a stereo pair. The correction of the displa...

Premodern Chinese texts pose problems that are difficult to accommodate with the current TEI text model, which bases the main hierarchy of a text on its structural content, rather than on a hierarchy that models the pages, lines and character positions. For the TEI, this is a sensible decision and has led to the abolishment of elements like and in the latest release of the Guideli...

We investigate mca-programs, that is, logic programs with clauses built of monotone cardinality atoms of the form kX , where k is a non-negative integer and X is a finite set of propositional atoms. We develop a theory of mca-programs. We demonstrate that the operational concept of the one-step provability operator generalizes to mca-programs, but the generalization involves nondeterminism. Our...
