1. 1. Transnationella utbildningsstrategier vid svenska lärosäten och bland svenska studenter i Paris och New York

   Författare :Mikael Börjesson; Donald Broady; Sverker Sörlin; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education; transnational educational strategies; higher education; globalisation; educational system; Paris; New York; sociology of education; Bourdieu; transnational capital; field; geometric data analysis; correspondence analysis; Euclidean classification; Pedagogik; Education; Pedagogik; Pedagogik; Education;

   Sammanfattning : Education is a neglected area within globalisation research, and, within educational research, very few studies have been devoted to transnational phenomena. In this study, transnational educational strategies are analysed as ingredients in social groups’ strategies, while the transnational investments of higher education institutions are understood primarily as resources in national educational field struggles.

3. 2. Data-Driven Classification in Road Networks

   Författare :Oliver Stromann; Zahra Gharaee; Alireza Razavi; Michael Felsberg; John Folkesson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Connected and autonomous vehicles (CAVs) are an emerging trend in the transport sector and their impact on transportation, the economy, society and the environment will be tremendous. Much like the automobile shaped the way humans travelled, lived and worked during the 20th century, CAVs have yet again the potential to affect and reform all of these areas. LÄS MER

4. 3. Nearest Neighbor Classification in High Dimensions

   Författare :Sampath Deegalla; Henrik Boström; Slawomir Nowaczyk; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nearest Neighbor; High-Dimensional Data; Curse of Dimensionality; Dimensionality Reduction; data- och systemvetenskap; Computer and Systems Sciences;

   Sammanfattning : The simple k nearest neighbor (kNN) method can be used to learn from high dimensional data such as images and microarrays without any modification to the original version of the algorithm. However, studies show that kNN's accuracy is often poor in high dimensions due to the curse of dimensionality; a large number of instances are required to maintain a given level of accuracy in high dimensions.

5. 4. Feature Extraction for Low-Frequency Signal Classification

   Författare :José Chilo; Thomas Lindblad; Christian Bohm; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; infrasound; seismic signals; feature extraction; wavelets; fingerprints; mining; multimodal data space; Atomic physics; Atomfysik; Electronics;

   Sammanfattning : The development of the International Monitoring System (IMS) for the verification of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has led to a rapid revival of interest in infrasound. Furthermore, the installation of low-frequency sensors at seismic sites has increased in recent years, providing researchers with large and heterogeneous data-sets in near real-time. LÄS MER

7. 5. Problems in the Classification Theory of Non-Associative Simple Algebras

   Författare :Erik Darpö; Ernst Dieterich; Karl-Heinz Fieseler; William Crawley-Boevey; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Division algebra; flexible algebra; normal form; composition algebra; absolute valued algebra; vector product; rotation.; MATHEMATICS; MATEMATIK;

   Sammanfattning : In spite of its 150 years history, the problem of classifying all finite-dimensional division algebras over a field k is still unsolved whenever k is not algebraically closed. The present thesis concerns some different aspects of this problem, and the related problems of classifying all composition and absolute valued algebras. LÄS MER
