2. 1. Cardiovascular disease and all-cause mortality : influence of fitness, fatness and genetic factors

   Author : Gabriel Högström; Anna Nordström; Peter Nordström; Johan Sundström; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; all-cause mortality; aerobic fitness; obesity; cardiovascular disease; stroke; myocardial infarction; Epidemiology; epidemiologi; Population studies; befolkningsstudier; Cardiology; kardiologi;

   Abstract : BackgroundLow aerobic fitness and obesity are associated with atherosclerosis, and thereforegreatly increase the risk of cardiovascular disease (CVD) and early death. It has long been known that atherosclerosis my begin early in life. READ MORE

4. 2. On wear of wood-cutting tools : Tool materials, wear mechanisms and modelling

   Author : Johan Nordström; []
   Keywords : Tool material; Wood cutting; Wear; Modelling;

   Abstract : Bandsaw blades are commonly used in the sawmill industry for timber cutting. The saw teeth are gradually worn during cutting and will finally cause unacceptable surface roughness and dimensional deviations on the sawn wood product. Maintenance by re-sharpening of the saw teeth is therefore necessary after a certain time of sawing. READ MORE

5. 3. Short Proofs May Be Spacious : Understanding Space in Resolution

   Author : Jakob Nordström; Johan Håstad; Albert Atserias; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proof complexity; resolution; space; length; width; separation; lower bound; pebble game; pebbling formula; Beviskomplexitet; resolution; minne; längd; bredd; separation; undre gräns; pebblingspel; pebblingformel; Theoretical computer science; Teoretisk datalogi;

   Abstract : Om man ser på de bästa nu kända algoritmerna för att avgöra satisfierbarhet hos logiska formler så är de allra flesta baserade på den så kallade DPLL-metoden utökad med klausulinlärning. De två viktigaste gränssättande faktorerna för sådana algoritmer är hur mycket tid och minne de använder, och att förstå sig på detta är därför en fråga som har stor praktisk betydelse. READ MORE

6. 4. Atomistic Spin Dynamics, Theory and Applications

   Author : Johan Hellsvik; Olle Eriksson; Lars Nordström; Ulrich Nowak; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ab initio calculations; spin dynamics; magnetization; magnetic switching; diluted magnetic semiconductors; spin glasses; ferromagnetic relaxation; ferrimagnets; antiferromagnets; Magnetism; Magnetism; Condensed matter physics; Kondenserade materiens fysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : The topic of this Thesis is magnetization dynamics on atomic length scales. A computational scheme, Atomistic Spin Dynamics, based on density functional theory, the adiabatic approximation and the atomic moment approximation is presented. READ MORE

7. 5. Analyzing Substation Automation System Reliability using Probabilistic Relational Models and Enterprise Architecture

   Author : Johan König; Lars Nordström; Sebastian Lehnhoff; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability analysis; substation automation; Enterprise Architecture; probabilistic analysis; Probabilistic Relational Models; Bayesian networks; software reliability; failure rates; fault tree analysis;

   Abstract : Modern society is unquestionably heavily reliant on supply of electricity. Hence, the power system is one of the important infrastructures for future growth. READ MORE
