1. Privacy Mechanism Design Through the Lens of Information Theory : With Applications to Compression, Caching, and Semantic Communication
Sammanfattning : Privacy mechanism design is an important research area and is receiving increased attention in recent years. This field focuses on addressing the challenge of revealing general data that might have correlations with sensitive information, all while protecting this sensitive information against unauthorized access.

2. With or without context : Automatic text categorization using semantic kernels
Sammanfattning : In this thesis text categorization is investigated in four dimensions of analysis: theoretically as well as empirically, and as a manual as well as a machine-based process. In the first four chapters we look at the theoretical foundation of subject classification of text documents, with a certain focus on classification as a procedure for organizing documents in libraries.

3. Privacy-by-Design for Cyber-Physical Systems
Sammanfattning : It is envisioned that future cyber-physical systems will provide a more convenient living and working environment. However, such systems need inevitably to collect and process privacy-sensitive information. That means the benefits come with potential privacy leakage risks. LÄS MER
4. Random Multigraphs : Complexity Measures, Probability Models and Statistical Inference
Sammanfattning : This thesis is concerned with multigraphs and their complexity which is defined and quantified by the distribution of edge multiplicities. Two random multigraph models are considered. The first model is random stub matching (RSM) where the edges are formed by randomly coupling pairs of stubs according to a fixed stub multiplicity sequence. LÄS MER
5. Ultralow noise pre-amplified receiver for free-space optical communications
Sammanfattning : The demand for high data rate in space communication links is increasing due to the growth of space exploration missions inter-satellite, and satellite-to-Earth data transmission. Optical communication systems capable of handling hundreds of Gigabits per second data transmission with a single light carrier and are suitable for such space links. LÄS MER
