It has been shown in various recent research reports that the analysis of short step primal dual path following algorithms for linear programming can be nicely generalized to semide nite programming How ever the analysis of long step path following algorithms for semide nite programming appeared to be less straightforward For such an algorithm Monteiro obtained an O n log iteration bound for ob...

The research and development of approaches to help students overcome the difficulties of acquiring good programming skills is a concern common to many institutions and researchers worldwide. One such approach is the use of virtual learning environments that allow students to freely explore several contextualized learning activities provided to them. We propose the use of scriptable 3D collabora...

Pitch and intensify ranges of 60 children were recorded and plotted in terms of phonetograms. Different aspects of the phonetograms were investigated, such as minimum phonation threshold, pitch range, and maximum dyrramic range. The vocal cord status of all children was determined in a phoniatric examination. Seven voice experts listened to recordings of the voices and rated their properties al...

This paper describes empirical results of information retrieval in 13 languages of the Cross Language Evaluation Forum (CLEF) collection augmented with results of Turkish using syllables as a means to manage morphological variation in the languages. This kind of approach has been used in speech retrieval (e.g. Larson and Eickeler 2003), but for some reason it has not been much tried out in text...

gramming and distribution which, when combined with novel uses of intellectual property law, has come to be known as “free software” or “open source software.” It is distinguished from other forms and practices of software production for many reasons, but most interestingly because its practitioners discuss it not simply in technical terms, but as a philosophy, a politics, a critique, a social ...

With the exploding size of genome databases it is becoming increasingly important to devise search procedures that extract relevant information from them One such procedure is particularly e ective in nding new distant members of a given family of related sequences start with a multiple alignment of the given members of the family and use an integral or fractional consensus sequence derived fro...

Given a multiprocessor system and a workload composed of several parallel programs , the processor allocation problem is to determine the number of processors that should be allocated to each parallel program. One simple, but common strategy is to give the entire system to an arriving job, thus executing the workload in a unipro-gramming, rst-come-rst-serve fashion. However, it is often possibl...

Current information retrieval systems typically ignore structural aspects of documents, solely focusing on the textual content instead. But documents containing additional structure in the form of HTML, XML, or SGML mark-up are pervasive on the Internet. The XML retrieval task presents a number of challenges for information retrieval, for we can no longer rely on the appropriate unit of retriev...

Many large MDPs can be represented compactly using a dynamic Bayesian network. Although the structure of the value function does not re­ tain the structure of the process, recent work has suggested that value functions in factored MDPs can often be approximated well using a factored value function: a linear combination of restr icted basis functions, each of which refers only to a small subset ...
