1. 1. Querying RDF Schema Views of Relational Databases

   Författare :Johan Petrini; Tore Risch; Larry Kerschberg; Uppsala universitet; []
   Nyckelord :query processing; partial evaluation; rdf; rdf schema; view; relational databases; semantic web;

   Sammanfattning : The amount of data found on the web today and its lack of semantics makes it increasingly harder to retrieve a particular piece of information. With the Resource Description Framework (RDF) every piece of information can be annotated with properties describing its semantics. LÄS MER

3. 2. Producing, Preventing, and Explaining Persistent Complex Subliminal Stimulation Effects

   Författare :Andreas Birgegård; Staffan Sohlberg; Mario Mikulincer; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Subliminal stimuli; persistent effects; attachment; relational schema; ethics; debriefing; interaction; motivation; sex differences; Psykologi; Psychology; Psykologi;

   Sammanfattning : Strong recent focus on unconscious processes has increased interest in subliminal stimulation and similar experimental technologies. Assumptions about the persistence of effects of unconscious stimulation are generally conservative, referring to seconds or minutes (Silverman, 1977; Velmans, 1991). LÄS MER

4. 3. Neutral intelligent CAD communication : information exchange in construction based upon a minimal schema

   Författare :Väino Tarandi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : An improved information exchange is frequently proposed asone solution to the inefficiency problems which theconstruction industry is suffering from today. Such animprovement is very dependent of the use of informationtechnology, IT. LÄS MER

5. 4. Scalable Preservation, Reconstruction, and Querying of Databases in terms of Semantic Web Representations

   Författare :Silvia Stefanova; Tore Risch; Stefan Decker; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RDF; RDFS; RDF view; SPARQL; SPARQL query processing; rewrite optimization; Topic Maps; querying of RDF views; archive relational databases; reconstruct archived databases; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Sammanfattning : This Thesis addresses how Semantic Web representations, in particular RDF, can enable flexible and scalable preservation, recreation, and querying of databases.An approach has been developed for selective scalable long-term archival of relational databases (RDBs) as RDF, implemented in the SAQ (Semantic Archive and Query) system.

7. 5. Modelling and evaluation of the effects of traffic safety measures Comparative analysis of driving assistance systems and road infrastructure

   Författare :Meng Lu; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vägtransportteknik; GRA; Road transport technology; grey relational analysis; driving assistance systems; traffic safety principle; quantitative causal chain; comparative analysis; QCC model; road infrastructure; road traffic safety;

   Sammanfattning : Improvement of road traffic safety is an important policy issue. Various categories of meas-ures are available to effectuate this. The thesis focuses on two categories: road infrastructure and driv-ing assistance systems. LÄS MER
