1. Context Sensitive Transformation of Geographic Information
Sammanfattning : This research is concerned with theoretical and methodological aspects of geographic information transformation between different user contexts. In this dissertation I present theories and methodological approaches that enable a context sensititve use and reuse of geographic data in geographic information systems. LÄS MER
2. How to Regulate Information and Communications Technology? : A Jurisprudential Inquiry into Legislative and Regulatory Techniques
Sammanfattning : ICT transformations digitalisation, computerisation and distributed networks have enabled emergence of new goods, services and applications that have changed the way behaviours are conducted. Moreover, ICT goods have been transformed into services, blurring established legal categories. LÄS MER
3. Sensitivity Analysis and Material Parameter Estimation using Electromagnetic Modelling
Sammanfattning : Estimating parameters is the problem of finding their values from measurements and modelling. Parameters describe properties of a system; material, for instance, are defined by mechanical, electrical, and chemical parameters. Fisher information is an information measure, giving information about how changes in the parameter effect the estimation. LÄS MER
4. Digital Power of Attorney for authorization in industrial cyber-physical systems
Sammanfattning : In the age of digitization, many Cyber-Physical Systems are semi-autonomous and have sufficient power and resources to perform tasks on behalf of users. This thesis defines an authorization technique to transfer the power of legitimate users to trusted CPS or IoT devices, allowing the device to sign or access resources on behalf of the user. LÄS MER
5. Applications of Information Inequalities to Linear Systems : Adaptive Control and Security
Sammanfattning : This thesis considers the application of information inequalities, Cramér-Rao type bounds, based on Fisher information, to linear systems. These tools are used to study the trade-offs between learning and performance in two application areas: adaptive control and control systems security. LÄS MER
