2. 1. Techniques for Improving Intrusion Detection

   Author : Magnus Almgren; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; IDS cooperation; IDS response; application-integrated IDS; computer security; intrusion detection; alert reasoning;

   Abstract : Intrusion detection systems (IDSs) have become a vital part of operational computer security. They are the last line of defense against malicious hackers and help to detect ongoing attacks and mitigate their damage. READ MORE

4. 2. Seawater intrusion risks and controls for safe use of coastal groundwater under multiple change pressures

   Author : Aikaterini Mazi; Georgia Destouni; Adrian Werner; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; seawater intrusion; coastal aquifer; tipping points; safe operating space; analytical solution; Physical Geography; naturgeografi;

   Abstract : In the era of intense pressures on water resources, the loss of groundwater by increased seawater intrusion (SWI), driven by climate, sea level and landscape changes, may be critical for many people living in commonly populous coastal regions. Analytical solutions have been derived here for interface flow in coastal aquifers, which allow for simple quantification of SWI under extended conditions from previously available such solutions and are suitable for first-order regional vulnerability assessment and mapping of the implications of climate- and landscape-driven change scenarios and related comparisons across various coastal world regions.

5. 3. Human response to wind turbine noise : perception, annoyance and moderating factors

   Author : Eja Pedersen; Sten Ljunggren; Högskolan i Halmstad; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Noise; Environmental exposure; Wind; Audio-visual interaction; Low-level noise exposure; NATURAL SCIENCES; NATURVETENSKAP; wind turbines; noise annoyance; sound perception; audio-visual interaction; low-level noise exposure;

   Abstract : Aims: The aims of this thesis were to describe and gain an understanding of how people who live in the vicinity of wind turbines are affected by wind turbine noise, and how individual, situational and visual factors, as well as sound properties, moderate the response.Methods: A cross-sectional study was carried out in a flat, mainly rural area in Sweden, with the objective to estimate the prevalence of noise annoyance and to examine the dose-response relationship between A-weighted sound pressure levels (SPLs) and perception of and annoyance with wind turbine noise.

6. 4. Modelling of Factors Influencing Foot Ankle Responses and Injuries in Car Crashes

   Author : Niklas Höglund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mathematical model; foot-ankle injuries; parameter study; toepan intrusion;

   Abstract : Foot and ankle injuries in frontal car collisions are believed to be caused mainly by occupant contact with the floor and toepan, occupant interaction with the pedals, and the lower leg being deformed between the floor and knee bolster. A better understanding of the causes of foot and ankle injuries is required to design cars for improved safety of the legs. READ MORE

7. 5. Foot-Ankle Joints Responses. Epidemiology, Biomechanics and Mathematical Modeling

   Author : Chantal S. Parenteau; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mathematical models; biomechanics; range of motion; ankle injury; injury mechanisms; ligament failure; center of rotation; ankle and subtalar joints; ankle fracture;

   Abstract : The purpose of this thesis is to acquire better knowledge of foot-ankle injuries because of their increasing importance in car crashes. Three approaches were used: epidemiology, biomechanics and mathematical modeling. READ MORE
