Spectral mapping and long-term seasonal evolution of Pluto
NASA's New Horizons mission has provided a wealth of new data about the Pluto system, including detailed surface geology and volatile distribution maps revealing striking latitudinal and longitudinal variations. We begin by studying the methane distribution and surface colors using data from New …

Accent Conversion via Formant-based Spectral Mapping and Pitch Contour Modification
… was investigated. Three different formant-based spectral mappingalgorithms, mean-variance linear conversion, Nth order non-linear conversion and piece-wise linear transformation based on Gaussian mixture model conversion were investigated. Furthermore, the project has implemented accent …

Development and spatio-spectral mapping of a capillary high harmonic source
… of the capillary launch). A study of the spectral output of the system as a function of gas pressure, laser power, and laser spectral phase. An analysis technique for recovering spatially-resolved spectral information about a beam by studying the Fresnel diffraction pattern produced at an …

Intensyvių femtosekundinių šviesos bangų paketų sklidimo Kero terpėse laikinis ir erdvinis charakterizavimas /
… allowed high resolution temporal, spatial and spectral mapping of light wave-packet dynamics during the nonlinear propagation in transparent media, and enabled to observe and make accurate quantitative evaluation of the ultrafast change of medium properties. By means of high temporal (20 fs) …

Almost commuting elements of real rank zero C∗-algebras
… Filonov and Safarov's results on approximate<br/>spectral projections in C-algebras of real rank zero.<br/>In Chapter 4 we prove an analogue of Lin's theorem for nite matrices with<br/>respect to the normalized Hilbert{Schmidt norm. It is a renement of a previously<br/>known result by Glebsky, and …

Segmentation of textured images
… texture segmentation adopted in this thesis is mapping a textured image into a grey level image so that conventional segmentation techniques by intensity can be applied. Three novel approaches to texture segmentation have been developed in this thesis. They are called the Local Feature …

Topological Structures in Ferroic Materials
… for a very small percentage of the film volume; spectral mapping of the films using EDX shows a homogeneous distribution of all three elements, so any cobalt-rich regions must be very small. Atomic-scale spectral mapping could provide more insight into this phenomenon.<br/><br/>The magnetic …
