Spike sorting is the task of grouping action potentials observed in extracellular electrophysiological recordings by source neuron. In this thesis a new incremental spike sorting model is proposed that accounts for action potential waveform drift over time, automatically eliminates refractory period violations, and can handle “appearance” and “disappearance” of neurons during the course of the ...

This work presents a methodology that uses digital fraction images derived from Linear Spectral Mixture Model and wavelets transform from MODIS satellite sensor time-series for land cover change analysis. Our approach uses MODIS surface reflectance images acquired from 2000 to 2006 time period. For this study, a test site was selected in the Mato Grosso State, Brazilian Amazonia. This site has ...

Improving the solubility and changing the dissolution rate of the poorly soluble active pharmaceutical ingredients (API’s) AMG 517, glipizide, and naproxen through the preparation of eutectic mixtures was investigated. Mixtures of the API’s with other small molecules were prepared to construct a phase diagram used to identify the eutectic mixture compositions. The search for a eutectic mixture ...

Crystal growth experiments (micro-pulling down or Czochralski methods, respectively) and DTA/TG measurements with Fe containing olivines (fayalite–forsterite solid solution) and with FeO (wustite) are performed. For both substances the oxygen partial pressure pO2 of the growth atmosphere had to be adjusted within the stability region of Fe 2+ for all temperatures ranging from room temperature t...

Synthesis gas, or syngas for short, is a mixture of CO, CO2, and H2 [...]

Instantaneous two-dimensional measurements of reaction rate, mixture fraction, and temperature are demonstrated in turbulent partially premixed methane/air jet flames. The forward reaction rate of the reaction CO OH ⇒ CO2 H is measured by simultaneous OH laser-induced fluorescence (LIF) and two-photon CO LIF. The product of the two LIF signals is shown to be proportional to the reaction rate. T...

The main objective of this research is to study the effects of JP-4-biodiesel-diesel fuel blends and operating parameters on the emission characteristics of a CI engine. The experimental tests were performed on a four-cylinder DI diesel engine. The Mixture-RSM method was used to develop mathematical models based on experimental data. The results showed that with the increase of the biodiesel pr...
