1. 16. Some matters of great balance

   Författare :Tomas Nilson; Cornelia Schiebold; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Balanced incomplete block design. Triple array. Balanced grid. Pseudo- Youden design. Youden square. Inner balance. Balanced for intersection. Soliton. Two-dimensional Toda lattice.;

   Sammanfattning : This thesis is based on four papers dealing with two different areas of mathematics.Paper I–III are in combinatorics, while Paper IV is in mathematical physics.In combinatorics, we work with design theory, one of whose applications aredesigning statistical experiments. LÄS MER

3. 17. Electron crystallography of soluble proteins

   Författare :Matthew James Ellis; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Interfacial crystallization; electron microscopy; image processing; soluble protein; phospholipid layer;

   Sammanfattning : Protein structures at moderate to high resolution can now be readily solved using an electron microscope and image processing techniques. The averaging conditions required to overcome the low signal to noise ratio of electron microscope images are particularly well satisfied by two-dimensional crystals. LÄS MER

4. 18. Some Contributions to Multi-Release Problems in Software Reliability and Successive Generations of Technologies

   Författare :Amir Soleimani Garmabaki; India Delhi New Delhi University of Delhi Dept. of Operational Research; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Software reliability is defined as the probability of failure-free software operation for a specified period of time in a specified environment. The software reliability model is the tool, which can be used to evaluate software quantitatively, develop test status, schedule status and monitor the changes in reliability performance. LÄS MER

5. 19. Discrete Scale-Space Theory and the Scale-Space Primal Sketch

   Författare :Tony Lindeberg; Jan-Olof Eklundh; Jan. J Koenderink; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer vision; low-level processing; scale-space; diffusion; Gaussian filtering; discrete smoothing; primal sketch; segmentation; descriptive elements; scale detection; image structure; focus-of-attention; tuning low-level processing; blob detection; edge detection; edge focusing; histogram analysis; junction classification; perceptual grouping; texture analysis; critical points; classification of blob events; bifurcations; drift velocity; density of local extrema; multi-scale representation; digital signal processing; Computer Science; Datalogi;

   Sammanfattning : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. LÄS MER

7. 20. Control of Cracking due to Imposed Strains in Concrete Structures

   Författare :Dan Pettersson; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; Friction.; Restraint; Shrinkage; Imposed deformations; Minimum reinforcement; Crack widths; Reinforced concrete; Crack development; Crack control; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

   Sammanfattning : This thesis is concerned with crack control due to imposed deformations in concrete structures. The objective of crack control may either be to prevent cracking or to limit the crack widths. The aim here is to increase the knowledge in both fields for some common structures. Five papers are included and the three last concern crack development. LÄS MER
