1. Bilinear Regression and Second Order Calibration
Sammanfattning : We consider calibration of second-order (or "hyphenated") instruments for chemical analysis. Many such instruments generate bilinear two-way (matrix) type data for each specimen. The bilinear regression model is to be estimated from a number of specimens of known composition. LÄS MER
2. Algorithms for a Partially Regularized Least Squares Problem
Sammanfattning : Vid analys av vattenprover tagna från t.ex. ett vattendrag betäms halten av olika ämnen. Dessa halter är ofta beroende av vattenföringen. LÄS MER
3. Algorithms in data mining using matrix and tensor methods
Sammanfattning : In many fields of science, engineering, and economics large amounts of data are stored and there is a need to analyze these data in order to extract information for various purposes. Data mining is a general concept involving different tools for performing this kind of analysis. LÄS MER
4. Computation of Parameters in some Mathematical Models
Sammanfattning : In computational science it is common to describe dynamic systems by mathematical models in forms of differential or integral equations. These models may contain parameters that have to be computed for the model to be complete. LÄS MER
5. Adipose Tissue Heterogeneity - Development and Application of Nonlinear Microscopy Methods
Sammanfattning : Although the negative health impacts of obesity have been well documented, the number of overweight or obese patients has and is predicted to continue rising. One of the causal factors of obesity is a constant positive energy balance mainly from excessively high caloric intake from food compared with limited physical activity (caloric expenditure). LÄS MER
