11. Finite-Length Scaling Laws for Spatially-Coupled LDPC Codes
Abstract : This thesis concerns predicting the finite-length error-correcting performance of spatially-coupled low-density parity-check (SC-LDPC) code ensembles over the binary erasure channel. SC-LDPC codes are a very powerful class of codes; their use in practical communication systems, however, requires the system designer to specify a considerable number of code and decoder parameters, all of which affect both the code’s error-correcting capability and the system’s memory, energy, and latency requirements.

12. Constraint-Driven Design Space Exploration for Memory-Dominated Embedded Systems
Abstract : Today, embedded systems often consist of many different processing, communication, and memory units. This makes an embedded system a multiprocessor system. There are usually many possible multiprocessor architectures and therefore we need tool support for fast evaluation of numerous design alternatives. READ MORE

13. Analysis of the Fatigue Characteristics of Mooring Lines and Power Cables for Floating Wave Energy Converters
Abstract : To reduce greenhouse gas emissions and expand the energy mix, there is a pressing need for the exploitation of renewable sources of energy, such as biomass, hydropower, solar power, waves, and wind. This thesis focuses on ocean wave energy and its applications. READ MORE

14. Energy Harvesting and Energy Storage for Wireless and Less-Wired Sensors in Harsh Environments
Abstract : Engineering requires sensors to control and understand the environment. This is particularly important in harsh environments. The drawbacks, especially in gas turbines is the complexity of installing a wired sensor and the weight of the wires. This makes wireless sensors attractive. READ MORE

15. Conjoined piezoelectric harvesters and carbon supercapacitors for powering intelligent wireless sensors
Abstract : To achieve total freedom of location for intelligent wireless sensors (IWS), these need to be autonomous. To achive this today there is a need of broadband piezoelectric energy harvesting and a long-lasting energy. The Harvester need to be able to provide sufficient amount of energy for the intelligent wireless sensor to perform its task. READ MORE
