11. Lossy and Lossless Compression Techniques to Improve the Utilization of Memory Bandwidth and Capacity
Sammanfattning : Main memory is a critical resource in modern computer systems and is in increasing demand. An increasing number of on-chip cores and specialized accelerators improves the potential processing throughput but also calls for higher data rates and greater memory capacity. LÄS MER
12. Modelling Aspects of Wastewater Treatment Processes
Sammanfattning : Wastewater treatment processes are inherently dynamic because of the large variations in the influent wastewater flow rate, concentration and composition. Moreover, these variations are to a large extent not possible to control. LÄS MER
13. Approximate Solution Methods to Optimal Control Problems via Dynamic Programming Models
Sammanfattning : Optimal control theory has a long history and broad applications. Motivated by the goal of obtaining insights through unification and taking advantage of the abundant capability to generate data, this thesis introduces some suboptimal schemes via abstract dynamic programming models. LÄS MER
14. Multidimensional inverse problems in imaging and identification using low-complexity models, optimal mass transport, and machine learning
Sammanfattning : This thesis, which mainly consists of six appended papers, primarily considers a number of inverse problems in imaging and system identification.In particular, the first two papers generalize results for the rational covariance extension problem from one to higher dimensions.

15. Simplified Graphical Approaches for CDMA Multi-User Detection, Decoding and Power Control
Sammanfattning : The individual optimal detector for code-division multiple-access (CDMA) systems is based on the marginal a posteriori distribution of the transmitted bits. The marginalization is in general hard since a summation is required, which grows exponentially in scope with the number of active users. LÄS MER
