1. 21. Electronic Cash and Hierarchical Group Signatures

   Författare :Mårten Trolin; Johan Håstad; Helger Lipmaa; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning : I denna avhandling presenteras resultat inom två områden – elektroniska betalningar och hierarkiska gruppsignaturer. • En starkare säkerhetsdefinition för digitala pengar presenteras med syfte att användare inte ska behöva lita på banken i samma utsträckning som för äldre definitioner.

3. 22. Hierarchical curvature estimation in computer vision

   Författare :Håkan Bårman; Gösta Granlund; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : This thesis concerns the estimation and description of curvature for computer vision applications. Different types of multi-dimensional data are considered: images (2D); volumes (3D); time sequences of images (3D); and time sequences of volumes (4D).The methods are based on local Fourier domain models and use local operations such as filtering.

4. 23. Hierarchical Methods for Self-Monitoring Systems : Theory and Application

   Författare :Pablo José Del Moral Pastor; Sławomir Nowaczyk; Sepideh Pashami; Niklas Lavesson; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Self-monitoring solutions first appeared to avoid catastrophic breakdowns in safety-critical mechanisms. The design behind these solutions relied heavily on the physical knowledge of the mechanism and its fault. They usually involved installing specialized sensors to monitor the state of the mechanism and statistical modeling of the recorded data. LÄS MER

7. 25. Hierarchical Modeling of Road Traffic Networks

   Författare :Eugene Merritt; KTH; []
   Nyckelord :traffic simulation models; calibration and validation; field data collection;

   Sammanfattning : The main objective of the thesis was to develop and applymethodologies for analysis and evaluation of the applicabilityof different types of road traffic simulation models for urbantraffic conditions. For this purpose a number of models ofmacroscopic, mesoscopic and microscopic type were applied,calibrated, validated and analyzed using extensive field datacollection to obtain traffic flow, travel time and queue-lengthdata for major road networks in Stockholm and Uppsala.
