5. 4. Female and Male Whole Spinal Alignment and Cervical Kinematic Responses in Rear Impacts

   Författare :Fusako Sato Sakayachi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neck injury; spinal alignment; whiplash; cervical vertebral kinematics; volunteer; Multi-Dimensional Scaling; rear impact; automotive seated posture; MRI; female;

   Sammanfattning : The susceptibility of women to Whiplash Associated Disorders (WADs) has been the focus of numerous epidemiologic studies. Summarising the epidemiologic WAD studies, women were found to be at three times higher risk of sustaining WADs than men. LÄS MER

7. 5. Solving the correspondence problem in analytical chemistry : Automated methods for alignment and quantification of multiple signals

   Författare :Erik Alm; Magnus Åberg; Beata Walczak; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

   Sammanfattning : When applying statistical data analysis techniques to analytical chemical data, all variables must have correspondence over the samples dimension in order for the analysis to generate meaningful results. Peak shifts in NMR and chromatography destroys that correspondence and creates data matrices that have to be aligned before analysis. LÄS MER
