Clustering similar documents is a difficult task for text data mining. Difficulties stem especially from the way documents are translated into numerical vectors. In this chapter, we will present a method that uses Self Organizing Map (SOM) to cluster medic ...
This paper proposes, for the first time, the investigation of the SG-FET small slope switch based on a hybrid numerical simulation approach combining ANSYS (TM) Multiphysics and ISE-DESSIS (TM) in a self-consistent system. The proposed hybrid numerical sim ...

This contribution presents a simple, unstructured math. model describing microbial growth in continuous culture limited by a gaseous substrate. It has been found that the parameters influencing growth are primarily the gas transfer rate and the diln. rate. ...
Product development (PD) processes are complex and unstructured compared to business or manufacturing processes, as they have iterative, evolutionary, uncertain, and cooperative features. In order to effectively manage and control a complex PD process, app ...
In this thesis, we investigate the effectiveness of semantic fisheye views for opportunistic search and sensemaking tasks over large collections of annotated images. Semantic fisheye views are interactive visualization techniques that reveal semantic detai ...
Many scientific applications are iterative and specify repetitive communication patterns. This paper shows how a parallel-language compiler and a predictive cache-coherence protocol in a distributed shared memory system together can implement shared-memory ...
In this paper we analyze the functional and non-functional requirements of peer-to-peer (P2P) systems that go beyond the needs of the well explored file-sharing P2P systems. Four basic subcategories are suggested to classify the non-functional requirements ...
By making use of two different laser spectroscopic techniques involving narrowband pulsed lasers in the visible, ultraviolet, and extreme-ultraviolet wavelength ranges, highly accurate data on absolute transition frequencies and predissociation rates were ...
The paper presents an in depth assessment of different similarity laws for the mean velocity profile in zero pressure gradient (ZPG) turbulent boundary layers (TBL's) in comparison with mostly experimental and few computational data. The emphasis is on the ...
Problem diagnosis for distributed systems is usually difficult. Thus, an automated support is needed to identify root causes of encountered problems such as performance lags or inadequate functioning quickly. The many tools and techniques existing today th ...
