1. Metamathematical fixed points
Sammanfattning : This thesis concerns the concept of metamathematical fixed points. After an introduction, we survey the field of metamathematics, from la fin du siècle to present. We are especially interested in the notion of fixed points, theorems on the existence of various kinds of fixed points, and their applications to metamathematics. LÄS MER
2. Residue fixed point index and wildly ramified power series
Sammanfattning : This thesis concerns discrete dynamical systems. These are systems where the dynamics is modeled by iterated functions. There are several applications of discrete dynamical system e.g. LÄS MER
3. Fixed Point Iterations for Finite Sum Monotone Inclusions
Sammanfattning : This thesis studies two families of methods for finding zeros of finite sums of monotone operators, the first being variance-reduced stochastic gradient (VRSG) methods. This is a large family of algorithms that use random sampling to improve the convergence rate compared to more traditional approaches. LÄS MER
4. Improving the Schedulability of Real Time Systems under Fixed Preemption Point Scheduling
Sammanfattning : During the past decades of research in Real-Time systems, non-preemptive scheduling and fully preemptive scheduling have been extensively investigated, as well as compared with each other. However, it has been shown that none of the two scheduling paradigms dominates over the other in terms of schedulability. LÄS MER
5. Aspects of Fixed-point Implementation of Multiuser Detctors in WCDMA
Sammanfattning : Wideband code-division multiple-access (WCDMA) has been selected as the radio technique standard for the 3G mobile communication systems. However, it is well known that the conventional single-user detector, which is commonly used in CDMA systems, suffers from multiple-access interference (MAI). LÄS MER
