2. 6. On Boolean Functions in Symmetric-Key Ciphers

   Author : Enes Pasalic; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autocorrelation properties; correlation attacks; nonlinearity; resiliency; Boolean function; Stream ciphers; block ciphers; Informatics; systems theory; Informatik; systemteori;

   Abstract : This thesis discusses new results on the design and the existence of cryptographically strong Boolean functions used in the design of stream and block ciphers. By interlinking theoretical results and computer search some open problems have been solved, that is, we have shown the existence of previously unknown classes of functions. READ MORE

4. 7. Executive functions and successful behavior

   Author : Torbjörn Vestberg; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Executive functions are the underlying mechanisms that drive top-down regulation of information processing. While suboptimal executive functions have been investigated in various groups of patients, their impact and contribution to behavioral success have not been clarified. READ MORE

5. 8. Affective Surface Engineering for Product Design

   Author : Martin Bergman; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; semantics; Design research; total appearance; soft metrology; surface roughness; technical functions; core values; product interaction; kansei engineering; emotional functions; hard metrology; sensation and perception;

   Abstract : Design research, sensation and perception, hard metrology, emotional functions, semantics, surface roughness, product interaction, core values, total appearance… the list of scientific phrases never ends. Yet, what do they mean and how shall we use it when we are communicating with the industry and our end users? Is it possible to link the product experience to process parameters, put a number onto it? When you can measure spoken needs or even better, implied needs, of a product, and relate that data to the production, it is possible do create advanced products with high interaction stimuli.

6. 9. Transition Properties of f-electrons in Rare-earth Optical Materials

   Author : Daniel Åberg; Börje Johansson; Sverker Edvardsson; Lidia Smentek; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; rare-earth ions; oscillator strengths; correlation; crystal field; f-electrons; Fysik; Physics; Fysik;

   Abstract : The main purpose of this thesis is to theoretically study energy levels and intra-electronic transition intensities for various f-electron systems. The f-f electronic dipole transitions are parity-forbidden for a free ion but become non-zero when the ion is subject to a crystal-field. READ MORE

7. 10. Assessment of central auditory functions : methods and applications

   Author : Mathias Hällgren; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Central auditory processing is complex and can not be completely evaluated by a single method. This thesis focuses on assessment of some aspects of central auditory functions by the use of dichotic speech tests, cognitive tests that tax functions important for speech processing and electrophysiological tests.
