1. 11. Analysis of Medical Images : Registration, Segmentation and Classification

   Författare :Matilda Landgren; Mathematical Imaging Group; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : A large number of medical examinations involve images in some way. Images can be used for diagnostics, follow-up studies and treatment planning. In this thesis mathematical methods have been developed and adapted in order to analyze medical images. LÄS MER

3. 12. Algorithm-Architecture Co-Design for Digital Front-Ends in Mobile Receivers

   Författare :Isael Diaz; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture Optimization; Digital Front End; Wireless Communication; Mobile terminal;

   Sammanfattning : The methodology behind this work has been to use the concept of algorithm-hardware co-design to achieve efficient solutions related to the digital front-end in mobile receivers. It has been shown that, by looking at algorithms and hardware architectures together, more efficient solutions can be found; i.e. LÄS MER

   Sammanfattning : We are surrounded by data in our daily lives. The rent of our houses, the amount of electricity units consumed, the prices of different products at a supermarket, the daily temperature, our medicine prescriptions, our internet search history are all different forms of data. Data can be used in a wide range of applications. LÄS MER

5. 14. Optimisation Challenges in Pressurised Hot Water Extraction of Polyphenols: Extraction and Degradation Kinetics

   Författare :Jiayin Liu; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Extraction kinetics; degradation kinetics; pressurised hot water extraction; optimisation; and anthocyanins; flavonoids; and polyphenols;

   Sammanfattning : Pressurised hot water is an environmentally friendly alternative to hazardous organic solvents such as methanol and heptane. One of the many applications of using pressurised hot water extraction (PHWE) is to extract polyphenols from plants. The challenges in PHWE lies with the optimisation of extraction yield. LÄS MER

7. 15. Graph theory based approaches for gene prioritization in biological networks : Application to cancer gene detection in medulloblastoma

   Författare :Hrafn Holger Weishaupt; Sergei Silvestrov; Erik Bongcam-Rudloff; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Sammanfattning : Networks provide an intuitive and highly adaptable means to model relationships between objects. When translated to mathematical graphs, they become further amenable to a plethora of mathematical operations that allow a detailed study of the underlying relational data. LÄS MER
