21. Reduced Receivers for Faster-than-Nyquist Signaling and General Linear Channels
Sammanfattning : Fast and reliable data transmission together with high bandwidth efficiency are important design aspects in a modern digital communication system. Many different approaches exist but in this thesis bandwidth efficiency is obtained by increasing the data transmission rate with the faster-than-Nyquist (FTN) framework while keeping a fixed power spectral density (PSD).

22. Clinical evaluation and implications of left atrial remodeling in atrial fibrillation : From silent cerebral lesions and atrial stunning to novel electrocardiographic tools for prediction of arrhythmia outcome
Sammanfattning : Atrial fibrillation (AF) is the most common cardiac arrhythmia. Left atrial (LA) remodeling and reverse remodeling are associated with cerebral involvement and cognitive function (CF) changes. Risk stratification for AF related outcomes is essential in the management of patients with AF. LÄS MER
23. Application of Differential Geometry to Elasticity and Corresponding Discrete Models
Sammanfattning : The amazing development in technology and industry during the last half of the twentieth century has opened totally new research fields. One of them is computational mechanics. Suddenly very complex, three-dimensional nonlinear engineering problems could be solved as a consequence of explosive advances in computers and numerical schemes. LÄS MER
24. Studies on unemployment duration and on the gender wage gap
Sammanfattning : Effects of Renewable Benefit Periods and Labour Market Programmes on the Exit Rate from UnemploymentThe main question addressed in this paper concerns the incentive effects of time-restricted unemployment benefits, as manifest in a rising exit rate from unemployment to employment when the moment of benefit exhaustion approaches: are these incentive effects lost when participation in labour market programmes is at hand as a way of renewing benefit eligibility? This renewal possibility is available as part of the Swedish unemployment insurance system. A piecewise-constant, proportional competing-risks hazard model is estimated using Swedish administrative data generated during the period 1994-1997. LÄS MER
25. Batch Control and Diagnosis
Sammanfattning : Batch processes are becoming more and more important in the chemical process industry, where they are used in the manufacture of specialty materials, which often are highly profitable. Some examples where batch processes are important are the manufacturing of pharmaceuticals, polymers, and semiconductors. LÄS MER
