6. Towards the Limits of Nonlinearity Compensation for Fiber-Optic Channels
Sammanfattning : The performance of long-haul coherent optical systems is fundamentally limited by fiber nonlinearity and its interplay with chromatic dispersion and noise. Due to nonlinearity, the signal propagating through the fiber interacts with itself and with the noise generated from the inline amplifiers. LÄS MER
7. Observer Design and Model Augmentation for Bias Compensation with Engine Applications
Sammanfattning : Control and diagnosis of complex systems demand accurate knowledge of certain quantities to be able to control the system efficiently and also to detect small errors. Physical sensors are expensive and some quantities are hard or even impossible to measure with physical sensors. This has made model-based estimation an attractive alternative. LÄS MER
8. Designing for Automated Digital Preservation : Model, Pre-Ingest, and Error Handling
Sammanfattning : With the rapid increase in the amount and complexity of data that is needed to be preserved, manual preservation activities produce complex, lengthy, and costly processes. Therefore, automation of preservation processes, together with modeling of workflows and streamlining, can help reduce costs and enhance the focus on preservation processes. LÄS MER
9. Phase Noise in Communication Systems--Modeling, Compensation, and Performance Analysis
Sammanfattning : The continuous increase in demand for higher data rates due to applications with massive number of users motivates the design of faster and more spectrum efficient communication systems. In theory, the current communication systems must be able to operate close to Shannon capacity bounds. LÄS MER
10. Dead-Time Compensation and Performance Monitoring in Process Control
Sammanfattning : The thesis contains two parts, dead-time compensation and performance monitoring. The first part on dead-time compensation is about robust tuning procedures for dead-time compensating controllers (DTC). Both stable and integrating processes are considered. LÄS MER
