1. 11. Analysis of Retroreflection and other Properties of Road Signs

   Författare :Roxan Saleh; Hasan Fleyeh; Darko Babić; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Road traffic signs; retroreflective sheeting material; night-time visibility; supervised machine learning; principal component analysis; prediction; linear regression;

   Sammanfattning : Road traffic signs provide regulatory, warning, guidance, and other important information to road users to prevent hazards and road accidents. Therefore, the traffic signs must be detectable, legible, and visible both in day and nighttime to fulfill their purpose. The nighttime visibility is critical to safe driving on the roads at night.

   Sammanfattning : Background Spinal pain is one of humanity’s most frequent complaints with high costs for the individual and society, and is commonly related to spinal disorders. There are many origins behind these disorders e.g., trauma, disc hernia or of other organic origins. LÄS MER

5. 14. Multivariate design of molecular docking experiments : An investigation of protein-ligand interactions

   Författare :David Andersson; Anna Linusson Jonsson; Gabriele Cruciani; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular docking; chemometrics; multivariate analysis; principal component analysis; PCA; design of experiments; DoE; partial least-square projections to latent structures; PLS; scoring functions; ligand-binding cavity; major histocompatibility complex; MHC; glycopeptide; T-cell.; Pharmaceutical chemistry; Läkemedelskemi; datorlingvistik; computational linguistics;

   Sammanfattning : To be able to make informed descicions regarding the research of new drug molecules (ligands), it is crucial to have access to information regarding the chemical interaction between the drug and its biological target (protein). Computer-based methods have a given role in drug research today and, by using methods such as molecular docking, it is possible to investigate the way in which ligands and proteins interact. LÄS MER

7. 15. Conjoint analysis as a tool for communication and corporate environmental decision-making

   Författare :Stina Alriksson; Tomas Öberg; Marianne Lindström; Högskolan i Kalmar; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conjoint analysis; PLS; Cluster analysis; Communication; Environmental; Decision-making; Environmental engineering; Miljöteknik; Miljövetenskap; Environmental Science;

   Sammanfattning : Conjoint analysis has been used extensively in marketing, transportation and healthcare for the past 50 years. Since the mid-1990s, it has also been applied to an increasing number of environmental issues. In this thesis, conjoint analysis is applied to environmental objectives of the Swedish steel industry.
