  1. 36. Shaping information security behaviors related to social engineering attacks

    Författare :Waldo Rocha Flores; Mathias Ekstedt; Stewart Kowalski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information security; Behavioral information security; Social engineering; Phishing; Measuring information security behaviors; Information security governance; Experiments; National culture; Mixed method research design; Quantitative methods; Industrial Information and Control Systems; Industriella informations- och styrsystem;

    Sammanfattning : Today, few companies would manage to continuously stay competitive without the proper utilization of information technology (IT). This has increased companies’ dependency of IT and created new threats that need to be addressed to mitigate risks to daily business operations. LÄS MER

    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Magnetic resonance imaging; digital image reconstruction; chemical shift imaging; water and fat separation; Dixon method; fat suppression; quantitative MRI; whole-body MRI; fatty acid composition; fat unsaturation; triglycerides; adipose tissue; liver fat; T2* mapping; Radiology; Radiologi; Radiology; Radiologi;

    Sammanfattning : Magnetic resonance imaging (MRI) is one of the most important diagnostic tools of modern healthcare. The signal in medical MRI predominantly originates from water and fat molecules. LÄS MER

  4. 38. Methods for Characterisation of Pressing Die Surfaces

    Författare :Johan C Berglund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finish milling; scale-sensitive fractal analysis; surface characterisation; polishing; functional correlation; : pressing dies; functional filtration; surface roughness; functional surface;

    Sammanfattning : Design and manufacture of dies and moulds is a critical aspect of many production systems since the manufacturing and try-out of new dies and moulds often is essential in determining the lead-time and quality of a new production system. In the automotive industry, many new car models are introduced each year and for each of these models, a new set of pressing dies has to be designed and manufactured. LÄS MER

  5. 39. Sensor-based knowledge- and data-driven methods : A case of Parkinson’s disease motor symptoms quantification

    Författare :Somayeh Aghanavesi; Mark Dougherty; Mobyen Uddin Ahmed; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Parkinson’s disease; motion sensors; motor symptoms; smartphone; microdata; multivariate analysis; data-driven; knowledge-driven; support vector machine stepwise regression; predictive models; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : The overall aim of this thesis was to develop and evaluate new knowledge- and data-driven methods for supporting treatment and providing information for better assessment of Parkinson’s disease (PD).PD is complex and progressive. There is a large amount of inter- and intravariability in motor symptoms of patients with PD (PwPD). LÄS MER

  7. 40. Measuring and modelling light scattering in paper

    Författare :Niklas Johansson; Per Edström; Mattias Andersson; Magnus Neuman; Jon Yngve Hardeberg; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; goniophotometry; anisotropy; angle resolved light scattering; reflectance measurements; turbid media;

    Sammanfattning : Avhandlingen behandlar de teoretiska och praktiska aspekterna av att använda spektrala vinkelupplösta reflektansmätningar för optisk karakterisering av fiberbaserade material såsom papper och kartong. En spektral goniofotometer används för att mäta det reflekterade ljusets vinkelfördelning. LÄS MER
