A Comparative Evaluation of a New Unsupervised Sentence Boundary Detection Approach on Documents in English and Portuguese
No full textIn this paper, we describe a new unsupervised sentence boundary detection system and present a comparative study evaluating its performance against dierent systems found in the literature that have been used to perform the task of automatic text segmentation into sentences for English and Portuguese documents. The results achieved by this new approach were as good as those of the previous systems, especially considering that the method does not require any additional training resources

The energy-critical nonlinear Schrodinger equation on a product of spheres
No full textHerr S, Strunk N. The energy-critical nonlinear Schrodinger equation on a product of spheres. Mathematical Research Letters. 2015;22(3):741-761.Let (M, g) be a compact smooth 3-dimensional Riemannian manifold without boundary. It is proved that the energy-critical nonlinear Schrodinger equation is globally well-posed for small initial data in H-1(M), provided that a certain tri-linear estimate for free solutions holds true. This estimate is known to hold true on the sphere and tori in 3d and verified here in the case S x S-2. The necessity of a weak form of this tri-linear estimate is also discussed

Measuring the lateral charge-carrier mobility in metal-insulator-semiconductor capacitors via Kelvin-probe
No full textWe report a Kelvin-probe method to investigate the lateral charge-transport properties of semiconductors, most notably the charge-carrier mobility. The method is based on successive charging and discharging of a pre-biased metal-insulator-semiconductor stack by an alternating voltage applied to one edge of a laterally confined semiconductor layer. The charge carriers spreading along the insulator-semiconductor interface are directly measured by a Kelvin-probe, following the time evolution of the surface potential. A model is presented, describing the device response for arbitrary applied biases allowing the extraction of the lateral charge-carrier mobility from experimentally measured surface potentials. The method is tested using the organic semiconductor poly(3-hexylthiophene), and the extracted mobilities are validated through current voltage measurements on respective field-effect transistors. Our widely applicable approach enables robust measurements of the lateral charge-carrier mobility in semiconductors with weak impact from the utilized contact materials
