1. 6. Applications of Knowledge Discovery in Quality Registries - Predicting Recurrence of Breast Cancer and Analyzing Non-compliance with a Clinical Guideline

   Författare :Amir Reza Razavi; Nosrat Shahsavar; Arie Hasman; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; Clinical guidelines; Canonical correlation analysis; Data Mining; Data pre-processing; Decision tree induction; Knowledge Discovery in Databases; Medical informatics; Medicinsk informatik;

   Sammanfattning : In medicine, data are produced from different sources and continuously stored in data depositories. Examples of these growing databases are quality registries. In Sweden, there are many cancer registries where data on cancer patients are gathered and recorded and are used mainly for reporting survival analyses to high level health authorities. LÄS MER

3. 7. Recycling of concrete in new structural concrete

   Författare :Madumita Sadagopan; Andrzej Cwirzen; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete recycling; sustainability; closed-loop recycling; recycled aggregates; compressive strength; workability mechanical pre-processing; secondary cementitious materials; green concrete; climate-optimized concrete; Resource Recovery; Resursåtervinning;

   Sammanfattning : Concrete waste as crushed concrete aggregates (CCA) in structural concrete gives a new purpose and prolongs the technical life of the reference concrete accomplishing closed loop recycling. This research investigates CCA as aggregate replacement in an industrial reference concrete recipe as fine aggregate fractions and overall aggregate replacement. LÄS MER

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Extreme Value Statistics; High-Throughput Screening; HTS; Bioinformatics; analysis of huge datasets; quality control; correction of theoretical p-values; comparison of pre-processing methods; SmartTail; estimation of False Discovery Rates; test power; distribution tail; high level excursions; quantile estimation; multiple testing; Student t−test; Welch statistic; small sample sizes; F−test; Wiener process; Gaussian random walk; Shepp statistic; limit theorems; exotic options.; estimation of False Discovery Rates;

   Sammanfattning : This thesis presents results in Extreme Value Theory with applications to High-Throughput Screening and Bioinformatics. The methods described here, however, are applicable to statistical analysis of huge datasets in general. The main results are covered in four papers. LÄS MER

5. 9. Interferometric measurements and analysis with applications in elastohydrodynamic experiments

   Författare :Olov Marklund; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Sammanfattning : Section A in this thesis is dedicated to measurements of lubricant films separating rotating surfaces in elastohydrodynamic experiments. Two specially designed interferometry-based methods are presented. A method to compensate for measurement errors due to the pressure dependence of the refractive index of the lubricant is proposed.

7. 10. Numerical Simulations of the Urban Microclimate

   Författare :Patricia Vanky; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD modelling; Immersed Boundary; Experimental validation; Wind comfort; Urban microclimate;

   Sammanfattning : As global urbanization is accelerating and the majority of the world's population continues to reside in cities, sustainable urban development is becoming increasingly crucial. Evaluation of the urban microclimate is a vital aspect of planning sustainable cities, as it can significantly impact on the health and comfort of urban residents. LÄS MER
