Within this chapter, the principles of numerical solar cell simulation are described, using AFORS-HET (automat for simulation of heterostructures). AFORS-HET is a one dimensional numerical computer program for modelling multi layer homoor heterojunction solar cells as well as some common solar cell characterization methods. Solar cell simulation subdivides into two parts: optical and electrical...

To write a \history of system identiication" is a formidable task and requires skills in science of history which I do not have. It is therefore unavoidable that an essay like this will be strongly subjective, and reeect my background, my personal interests and my personal recollections. The limitations in this presentation are thus set by my own background. I joined the Division of Automatic C...

In this paper we give a brief explanation of how Anchor Concept and Sub-Ontology based Ontology Matching (SOBOM) gets the alignment results at OAEI2009. SOBOM deal with the ontology from two different views: an ontology with is-a hierarchical structure ' O and an ontology with other relationships ' ' O . Firstly, from the ' O view, SOBOM starts with a set of anchor concepts provided by linguist...

the control law (3) does not only improves the transient performance, but also provides smoother outputs. It is important to stress that a better performance can still be achieved with (28) and (30). However, as discussed in Remark IV.1, increasing gains would not only cause more peaks in the outputs, but it might also yield saturation, especially for 2. V. CONCLUSION The tracking control probl...

Now-a-days Computer Assisted Language Learning (CALL) systems for rehabilitation purposes involving rhythmic analysis and prosodic analysis which are inter-related have gained much importance in speech synthesis and recognition systems. The main objective is to develop a language learning system by monitoring and evaluating the prosodic variations and content data corresponding to the pronuncia...

Most recent research in trainable part of speech taggers has explored stochastic tagging. While these taggers obtain high accuracy, linguistic information is captured indirectly, typically in tens of thousands of lexical and contextual probabilities. In [Brill 92], a trainable rule-based tagger was described that obtained performance comparable to that of stochastic taggers, but captured releva...

Polysemy is one of the major causes of difficulties in selnantic clustering of words in a corpus. In this paper, we first; give a definition of polysemy from the viewpoint of clustering and then, b~rsed on this definition, we propose a clustering method which reeognises verbal 1)olysemics from a textual corpus. The results of experiments denmnst ra te the effectiveness of the proI)osed method. ...

In fo rmat ion Access research at Xerox PARC focuses on ampl i f y ing the users' cognitive abil i t ies, rather than t r y i ng to completely automate them. This framework emphasizes the par t ic ipat ion of the user in a cycle of query fo rmu la t ion , presentation of results, followed by query re formulat ion, and so on. Th is framework is intended to help the user i teratively refine a vag...
