3. 17. Baking volume of wheat flour : assessment of novel analyses and parameters in prediction

   University essay from SLU/Department of Molecular Sciences

   Author : Assar Sundholm; [2021]
   Keywords : baking volume; wheat flour; Alveolab; SDmatic; SRC 2;

   Abstract : In the milling industry baking volume is used as the gold standard for wheat flour quality. Determination of baking volume is a time-consuming and blunt method, demanding a quicker and more precise substitute. The aim of this thesis was to assess how different rheological and chemical parameters affect baking volume. READ MORE

4. 18. Machine learning methods for seasonal allergic rhinitis studies

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Zijie Feng; [2021]
   Keywords : Machine learning; Seasonal allergic rhinitis; Random forest; Partial least squares discriminant analysis; Bootstrap; Cubic smoothing splines; Single-cell RNA sequencing;

   Abstract : Seasonal allergic rhinitis (SAR) is a disease caused by allergens from both environmental and genetic factors. Some researchers have studied the SAR based on traditional genetic methodologies. As technology develops, a new technique called single-cell RNA sequencing (scRNA-seq) is developed, which can generate high-dimension data. READ MORE

5. 19. Quantifying nitrogen oxides and ammonia via frequency modulation in gas sensors

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Marcos Freitas Mourao dos Santos; [2021]
   Keywords : Nitrogen oxides; nox; ammonia; sic-fet; PLSR; quantification;

   Abstract : The use of Silicon Carbide Field Effect Transistor (SiC-FET) sensors in cyclic operation is a proven way to quantify different gases. The standard workflow involves extracting shape-defining features such as averages and slopes of the sensor signal. READ MORE

6. 20. Bayes Factors for the Proposition of a Common Source of Amphetamine Seizures.

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Yash Pawar; [2021]
   Keywords : Amphetamine Data; LDA; PLS-DA; NSC; Gaussaianize; pairwise ratios;

   Abstract : This thesis sets out to address the challenges with the comparison of Amphetamine material in determining whether they originate from the same source or different sources using pairwise ratios of peak areas within each chromatogram of material and then modeling the difference between the ratios for each comparison as a basis for evaluation. The evaluation of an existing method that uses these ratios to determine the sum of significant differences between each comparison of material that is provided is done. READ MORE
