1. 1. Holographic Wilson Loops : Quantum String Corrections

   Författare :Daniel Ricardo Medina Rincon; Konstantin Zarembo; Gianluca Grignani​; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gauge-string correspondence; AdS CFT; Wilson loops; String theory; Theoretical Physics; Teoretisk fysik;

   Sammanfattning : The gauge-string duality has been one of the most exciting areas in theoretical physics as it connects strongly coupled field theories with weakly interacting strings. The present thesis concerns the study of Wilson loops in this correspondence. LÄS MER

3. 2. Structures of String Matching and Data Compression

   Sammanfattning : This doctoral dissertation presents a range of results concerning efficient algorithms and data structures for string processing, including several schemes contributing to sequential data compression. It comprises both theoretic results and practical implementations. LÄS MER

4. 3. Ontology Integration with Non-Violation Check and Context Extraction

   Författare :Dan Wu; Anne Håkansson; Carl-Gustaf Jansson; Paul Johannesson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ontology matching and integration; semantic and pragmatic matching; semantic techniques; context; ontology and rules; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Matching and integrating ontologies has been a desirable technique in areas such as data fusion, knowledge integration, the Semantic Web and the development of advanced services in distributed system. Unfortunately, the heterogeneities of ontologies cause big obstacles in the development of this technique. LÄS MER

5. 4. Multifont recognition System for Ethiopic Script

   Författare :Yaregal Assabie Lake; Josef Bigun; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ethiopic character recognition; OCR; Multifont recognition; Amharic; Direction fields; Structural and syntactic pattern recognition; Image analysis; Bildanalys;

   Sammanfattning : In this thesis, we present a general framework for multi-font, multi-size and multi-style Ethiopic character recognition system. We propose structural and syntactic techniques for recognition of Ethiopic characters where the graphically comnplex characters are represented by less complex primitive structures and their spatial interrelationships.

7. 5. Automated Subject Classification of Textual Documents in the Context of Web-Based Hierarchical Browsing

   Författare :Koraljka Golub; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Dewey Decimal Classification; Engineering Information; hierarchical browsing; controlled vocabularies; thesauri; classification schemes; Automated classification; subject classification; Artificial intelligens; Artificiell intelligens; Library and Information Science;

   Sammanfattning : With the exponential growth of the World Wide Web, automated subject classification has become a major research issue. Organizing web pages into a hierarchical structure for subject browsing has been gaining more recognition as an important tool in information-seeking processes. LÄS MER
