2. 1. On Some Symmetric Lightweight Cryptographic Designs

   Author : Martin Ågren; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight cryptography; integrity; authentication; symmetric cryptography; stream ciphers; block ciphers; Grain-128a; BEAN; KTANTAN; textsc{PRINTcipher}; FCSR combiner; related-key attack; linear cryptanalysis; linear correlations; invariant subspace attack.;

   Abstract : This dissertation presents cryptanalysis of several symmetric lightweight primitives, both stream ciphers and block ciphers. Further, some aspects of authentication in combination with a keystream generator is investigated, and a new member of the Grain family of stream ciphers, Grain-128a, with built-in support for authentication is presented.

4. 2. Models and Simulations of the Electric Field in Deep Brain Stimulation : Comparison of Lead Designs, Operating Modes and Tissue Conductivity

   Author : Fabiola Alonso; Karin Wårdell; Simone Hemm; Johannes D Johansson; Fernando Seoane; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Deep brain stimulation (DBS) is an established surgical therapy for movement disorders such as Parkinson’s disease (PD) and essential tremor (ET). A thin electrode is implanted in a predefined area of the brain with the use of stereotactic neurosurgery. READ MORE

5. 3. Some matters of great balance

   Author : Tomas Nilson; Cornelia Schiebold; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Balanced incomplete block design. Triple array. Balanced grid. Pseudo- Youden design. Youden square. Inner balance. Balanced for intersection. Soliton. Two-dimensional Toda lattice.;

   Abstract : This thesis is based on four papers dealing with two different areas of mathematics.Paper I–III are in combinatorics, while Paper IV is in mathematical physics.In combinatorics, we work with design theory, one of whose applications aredesigning statistical experiments. READ MORE

6. 4. Optimal Design and Inference for Correlated Bernoulli Variables using a Simplified Cox Model

   Author : Daniel Bruce; Hans Nyquist; Werner G. Müller; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cox binary model; correlated binary data; log-odds ratio; D-optimality; E-optimality; power maximization; efficiency; Statistics; Statistik; statistik; Statistics;

   Abstract : This thesis proposes a simplification of the model for dependent Bernoulli variables presented in Cox and Snell (1989). The simplified model, referred to as the simplified Cox model, is developed for identically distributed and dependent Bernoulli variables. READ MORE

7. 5. Simulation of mechanical joining for automotive applications

   Author : Johannes Gårdstam; Anders Eriksson; Kjell Simonsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other materials science; Övrig teknisk materialvetenskap;

   Abstract : Regarding the use of material, modern lightweight car bodies are becoming more and more complex than previous constructions. The materials nowadays are used for a more specific field of application and more high strength steels are used and also other materials like aluminium, stainless steel, reinforced polymers are used more frequent.
