2. 1. FINGERPRINT IMAGE ENHANCEMENT, SEGMENTATION AND MINUTIAE DETECTION

   Author : Josef Ström Bartunek; Ingvar Claesson; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptive fingerprint image enhancement; fingerprint segmentation; gray-scale image normalization; minutiae features; neural networks; frequency analysis; kurtosis;

   Abstract : Prior to 1960's, the fingerprint analysis was carried out manually by human experts and for forensic purposes only. Automated fingerprint identification systems (AFIS) have been developed during the last 50 years. The success of AFIS resulted in that its use expanded beyond forensic applications and became common also in civilian applications. READ MORE

4. 2. Computed Tomography and Fingerprint Traceability in the Wood Industry

   Author : Erik Johansson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Abstract : The purpose of the work described in this thesis was to develop techniques based on non-invasive measurements of logs and sawn timber that would increase the profitability of the wood industry in general and sawmills in particular. The work has two main focus areas: computed tomography (CT) scanning of logs and traceability of wood products. READ MORE

5. 3. Heparan Sulfate Biosynthesis – Clues from Knockout Mice

   Author : Johan Ledin; Lena Kjellén; John Gallagher; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; heparan sulfate; biosynthesis; gene targeting; embryonic development; proteoglycans; NDST; N-deacetylase N-sulfotransferase; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

   Abstract : In the extracellular space, many specialized proteins are located to support cells and to mediate cell-cell signalling. One class of such molecules is heparan sulfate (HS) proteoglycans, which are proteins with different properties and locations but all of them decorated with long unbranched HS polysaccharide chains.

6. 4. Multivariate profiling of metabolites in human disease : Method evaluation and application to prostate cancer

   Author : Elin Thysell; Henrik Antti; Janne Lehtiö; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolite profiling; metabolomics; predictive metabolomics; mass spectrometry; GC-MS; biomarkers; chemometrics; design of experiments; multivariate data analysis; prostate cancer; bone metastases; plasma; biologisk kemi; biological chemistry;

   Abstract : There is an ever increasing need of new technologies for identification of molecular markers for early diagnosis of fatal diseases to allow efficient treatment. In addition, there is great value in finding patterns of metabolites, proteins or genes altered in relation to specific disease conditions to gain a deeper understanding of the underlying mechanisms of disease development.

7. 5. Compact orientation and frequency estimation with applications in biometrics : Biometrics on the orientation express

   Author : Anna Mikaelyan; Josef Bigun; Kenneth Nilsson; Raffaele Cappelli; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Automatic feature extraction still remains a relevant image and signal processing problem even tough both the field and technologies are developing rapidly. Images of low quality, where it is extremely difficult to reliably process image information automatically, are of special interest. READ MORE
