31. Computational Diffusion MRI: Optimal Gradient Encoding Schemes
Sammanfattning : Diffusion-weighted magnetic resonance imaging (dMRI) is a non-invasivestructural imaging technique that provides information about tissue microstructures.Quantitative measures derived from dMRI reflect pathologicaland developmental changes in living tissues such as human brain.

32. Carbon-nanotube-based nanoelectromechanics
Sammanfattning : Carbon nanotubes, a novel material with extraordinary mechanical and electrical properties, are good candidates for designing nanoelectromechanical systems. The typical length scale of these systems is nanometers and an important characteristic is a coupling between electrical and mechanical degrees of freedom. LÄS MER
33. Microwave Measurement Systems for Parameter Estimation and Classification
Sammanfattning : Microwave measurement systems are attractive for diagnostics and monitoring purposes in a number of important applications. For example, the strong interaction between microwaves and water make microwaves well-suited for moisture measurements. LÄS MER
34. Search for efficient time integration methods in structural dynamics for finite element meshes with large variations of properties
Sammanfattning : Direct time integration methods are the most commonly used solution algorithms for analysis of non-linear transient phenomena in finite element computations. One major disadvantage with these methods is that stability and accuracy of the computation are governed by the smallest element in the mesh assuming all other properties constant. LÄS MER
35. Parameter Estimation and Waveform Fitting for Narrowband Signals
Sammanfattning : Frequency estimation has been studied for a large number of years. One reason for this is that the problem is easy to understand, but difficult to solve. Another reason, for sure, is the large number of applications that involve frequency estimation, e. LÄS MER
