1. 1. 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. 2. Trial of labour after caesarean

   Författare :Charlotte Lindblad Wollmann; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Induction of labour;

   Sammanfattning : Background: Induction of labour and caesarean delivery are common interventions in obstetric care and over the last decades both have been steadily increasing in frequency worldwide. The two interventions are concatenated, since many of the indications for either intervention often are the same, and approximately 20-40% of all inductions in first time mothers ends with a caesarean delivery.

4. 3. Conifer chemical defense : Rugulation of bark beetle colonization and pheromone emission

   Författare :Tao Zhao; Anna-Karin Borg-Karlson; Irena Valterova; KTH; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Picea abies; Ips typographus; Ceratocystis polonica; methyl jasmonate; windstorm; stress response; terpenes; phenols; colonization; pheromone emission; Plant and forest protection; Växt- och skogsskydd;

   Sammanfattning : Terpenes and phenols are of importance in conifer defense against insects and pathogens. Knowledge about tree chemical defense is vital for developing practical methods to maintain healthy forests. LÄS MER

5. 4. Gene finding in Populus- The Bioinformatics of a EST program

   Författare :Rupali Bhalerao; KTH; []
   Nyckelord :;

   Sammanfattning : During the course of the work described in this thesis, ESTsequencing project was initiated in woody plant poplar forlarge scale gene discovery in a tree specie. Since most of thetree genomes are considerably large in size, EST sequencing wasconsidered to be a cost effective method for gene discovery. LÄS MER

7. 5. Learning Decision Trees and Random Forests from Histogram Data : An application to component failure prediction for heavy duty trucks

   Författare :Ram Bahadur Gurung; Henrik Boström; Tony Lindgren; Stockholms universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; histogram decision trees; histogram random forest; prognostics; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : A large volume of data has become commonplace in many domains these days. Machine learning algorithms can be trained to look for any useful hidden patterns in such data. Sometimes, these big data might need to be summarized to make them into a manageable size, for example by using histograms, for various reasons. LÄS MER
