Colour-temperature (Tc) is a crucial specification of white light-emitting diodes (WLEDs) used in a variety of smart-lighting applications. Commonly, Tc is controlled by distributing various phosphors on top of the blue or ultra violet LED chip in conventional phosphor-conversion WLEDs (PC-WLEDs). Unfortunately, the high cost of phosphors, additional packaging processes required, and phosphor d...

The Euroling stemmer is developed for a commercial web site and intranet search engine called SiteSeeker. SiteSeeker is basically used in the Swedish domain but to some extent also for the English domain. CST’s lemmatiser comes from the Center for Language Technology, University of Copenhagen and was originally developed as a research prototype to create lemmatisation rules from training data. ...

We present new parallel sorting networks for 17 to 20 inputs. For 17, 19, and 20 inputs these new networks are faster (i.e., they require less computation steps) than the previously known best networks. Therefore, we improve upon the known upper bounds for minimal depth sorting networks on 17, 19, and 20 channels. The networks were obtained using a combination of hand-crafted first layers and a...

There is no reason to accept the doctrines crafted to sustain power and privilege, or to believe that we are constrained by mysterious and unknown social laws. These are simply decisions made within institutions that are subject to human will and that must face the test of legitimacy. And if they do not meet the test, they can be replaced by other institutions that are more free and more just, ...

If given manually-crafted goal selection knowledge, goal reasoning agents can dynamically determine which goals they should achieve in complex environments. These agents should instead learn goal selection knowledge through expert interaction. We describe T-ARTUE, a goal reasoning agent that performs case-based active and interactive learning to discover goal selection knowledge. We also report...

In this paper, we present BioEve a fully automated event extraction system for bio-medical text. It first semantically classifies each sentence to the class type of the event mentioned in the sentence, and then using high coverage hand-crafted rules, it extracts the participants of that event. We participated in Task 1 of BioNLP 2009 Shared task, and the final evaluation results are described h...

The Web catalogs like Yahoo! and Open Directory are very useful for browsing and querying the Web. Although they index only a fraction of the pages that are indexed by search engines these catalogs are hand-crafted by domain experts and are therefore of high quality. We present a model for building mediators over Web catalogs, so as to provide users with cus-tomized views of such catalogs. We f...

The work presented here explains a framework to build semantic annotated maps from laser range measurements of a mobile robot. A hand-crafted and a learning classifier is explained. Two alternative methods to aggregate the resulting class membership vectors into a grid map have been developed and are presented. Both alternative methods will be motivated and described in detail and discussed cri...

We compare machine learning approaches for sentence length reduction for automatic generation of subtitles for deaf and hearing-impaired people with a method which relies on hand-crafted deletion rules. We describe building the necessary resources for this task: a parallel corpus of examples of news broadcasts of the Flemish VRT broadcasting corporation, and a Dutch shallow parser based on the ...

We propose a novel knowledge-rich approach to measuring the similarity between a pair of words. The algorithm is tailored to Bulgarian and Russian and takes into account the orthographic and the phonetic correspondences between the two Slavic languages: it combines lemmatization, hand-crafted transformation rules, and weighted Levenshtein distance. The experimental results show an 11-pt interpo...
