1. Multidimensional Piecewise Regular Arrays
Abstract : Regular arrays, particularly systolic arrays, have been the subject of continuous interest for the past 15 years. One reason is that they present an excellent example of the unity between hardware and software, especially for application-specific computations. READ MORE

2. Numerical and experimental modelling for wave energy arrays optimization
Abstract : Many wave power conversion devices, especially point-absorbers, do not provide alone the necessary amount of converted electricity to be cost effective, instead they are designed to be deployed in arrays of many units. Such arrays, or parks, can satisfy a large-scale energy demand, reduce the costs of the produced electricity and improve the reliability of the system. READ MORE

3. Single and Accumulative Electron Transfer – Prerequisites for Artificial Photosynthesis
Abstract : Photoinduced electron transfer is involved in a number of photochemical and photobiological processes. One example of this is photosynthesis, where the absorption of sunlight leads to the formation of charge-separated states by electron transfer. READ MORE

4. Characterisation and modelling of graphene FET detectors for flexible terahertz electronics
Abstract : Low-cost electronics for future high-speed wireless communication and non-invasive inspection at terahertz frequencies require new materials with advanced mechanical and electronic properties. Graphene, with its unique combination of flexibility and high carrier velocity, can provide new opportunities for terahertz electronics. READ MORE

5. On MIMO Systems and Adaptive Arrays for Wireless Communication : Analysis and Practical Aspects
Abstract : This thesis is concerned with the use of multiple antenna elements in wireless communication over frequency non-selective radio channels. Both measurement results and theoretical analysis are presented. New transmit strategies are derived and compared to existing transmit strategies, such as beamforming and space-time block coding (STBC). READ MORE
