1. 36. Sea Ice and Ocean Environmental Applications of Spaceborn SAR

   Författare :Sverre Thune Dokken; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radarsat; SSM I; ERS-1 2; ocean applications; sea ice applications; numerical models; SAR; Arctic Ocean; Envisat; climate change;

   Sammanfattning : The worldwide focus on our changing environment has led to an increased need to observe and characterise a range of environmental phenomena. The Arctic Ocean is particularly sensitive to climate variations. LÄS MER

3. 37. Beslutsfattande i klinisk verksamhet : En studie om sjuksköterskans beslutsfattande i praktiken

   Författare :Berith Hedberg; Sahlgrenska akademin vid Göteborgs univ. Institutionen för vårdpedagogik; []
   Nyckelord :decision-making; nursing practice; decision-making tools; environmental elements; interviews; participated observation; content analysis;

   Sammanfattning : The overall aim of the project was to investigate how decision-making is expressed by experienced nurses in practice. A research questions were to describe how nurses make decisions of measures in practice and another research question were to explore contextual elements related to decision-making in nursing practice.

4. 38. Methodology for Handling Missing Data in Nonlinear Mixed Effects Modelling

   Författare :Åsa M. Johansson; Mats O. Karlsson; Andrew C. Hooker; Leon Aarons; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; population models; censored observations; missing covariates; missing dependent variable; missing data mechanism; missing completely at random MCAR ; missing at random MAR ; missing not at random MNAR ; estimation algorithms; Pharmaceutical Science; Farmaceutisk vetenskap;

   Sammanfattning : To obtain a better understanding of the pharmacokinetic and/or pharmacodynamic characteristics of an investigated treatment, clinical data is often analysed with nonlinear mixed effects modelling. The developed models can be used to design future clinical trials or to guide individualised drug treatment. LÄS MER

5. 39. Unveiling a multi-scale view of massive star and cluster formation

   Författare :Chi Yan Law; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; massive stars; methods:observation; magnetic field; stars:formation; ISM:clouds;

   Sammanfattning : Massive stars regulate the physical and chemical evolution of galaxies. Most stars within these galaxies, including massive ones, appear to be born in star clusters. However, there are many open questions about how these systems form from diffuse interstellar gas. LÄS MER

7. 40. Tracking the Wanders of Nature

   Författare :Clas Veibäck; Gustaf Hendeby; Fredrik Gustafsson; Hans Driessen; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Target Tracking; Sensor Fusion; Motion Models; Animals; Cameras; Radar;

   Sammanfattning : Target tracking is a mature topic with over half a century of mainly military and aviation research. The field has lately expanded into a range of civilian applications due to the development of cheap sensors and improved computational power. LÄS MER
