1. Numerical Methods for Wave Propagation : Analysis and Applications in Quantum Dynamics
Sammanfattning : We study numerical methods for time-dependent partial differential equations describing wave propagation, primarily applied to problems in quantum dynamics governed by the time-dependent Schrödinger equation (TDSE). We consider both methods for spatial approximation and for time stepping. LÄS MER
2. Spectral Estimation by Geometric, Topological and Optimization Methods
Sammanfattning : .... LÄS MER
3. Advanced Spectral Analysis with Applications
Sammanfattning : Spectral analysis has advanced the last decades as a signal processing tool to extract significant information about certain properties of measured data. The practical use of spectral analysis techniques in time-series analysis has been emphasized in the immense amount of previous literature in the field and by a rapidly growing number of applications.

4. Spectral Methods for Self-Assembly
Sammanfattning : Conventional manufacturing relies on robotics and chemistry to create, shape and combine components into products. Nature shows us an alternative route: by carefully designing interactions between components, they can be made to spontaneously self-assemble into complex arrangements. LÄS MER
5. Prediction of random vibration using spectral methods
Sammanfattning : Much of the vibration in fast moving vehicles is caused bydistributed random excitation, such as turbulent flow and roadroughness. Piping systems transporting fast flowing fluid isanother example, where distributed random excitation will causeunwanted vibration. LÄS MER
