1. 1. Complex activity recognition and context validation within social interaction tools

   Författare :Saguna Saguna; Christian Becker; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; context awareness; activity recognition; social networks; situation awareness; HCI; complex activity recognition; sensors; Prototype evaluation; SACAAR; OAT4CDAT; online activity toolkit; context driven activity theory; wearable computing; smart homes; presence; machine learning; Markov chains; Pervasive Mobile Computing; Distribuerade datorsystem;

   Sammanfattning : Human activity recognition using sensing technology is crucial in achieving pervasive and ubiquitous computing paradigms. It can be applied in many domains such as health-care, aged-care, personal-informatics, industry, sports and military. LÄS MER

3. 2. Investigating the activation and regulation of the proteasome : an essential proteolytic complex

   Författare :Patrick Masson; Patrick Young; Marcus Groettrup; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteasome; PA28gamma; Transcriptional regulation; Drosophila; 26S; Molecular biology; Molekylärbiologi;

   Sammanfattning : The proteasome is a major non-lysosomal proteolytic complex present in eukaryotic cells and has a central role in regulating many protein levels. The complex has been shown to participate in various intracellular pathways including cell cycle regulation or quality control of newly synthesized proteins and many other key pathways. LÄS MER

4. 3. Mellan människor och ting : En interaktionistisk analys av samlandet

   Sammanfattning : Over the last few decades, computer simulation techniques have been established as an essential tool for understanding biochemical processes. This thesis deals mainly with the application of free energy calculations to ribosomal complexes and a cardiac ion channel. LÄS MER

7. 5. Machine learning for identification of brain activity patterns with applications in gentle touch processing

   Författare :Malin Björnsdotter Åberg; Göteborgs universitet; []
   Nyckelord :Somatosensory; Machine learning; Pattern recognition; fMRI; Support vector machines; Neuroscience; Brain; BOLD; Signal processing; Artificial intelligence; Touch; Human; Unmyelinated; Sensory; Affective;

   Sammanfattning : Since the first mention of artificial intelligence in the 1950s, the field of machine learning has provided increasingly appealing tools for recognition of otherwise unintelligible pattern representations in complex data structures. Human brain activity, acquired using functional magnetic resonance imaging (fMRI), is a prime example of such complex data where the utility of pattern recognition has been demonstrated in a wide range of studies recently (Haynes et al.
