Bayesian Signal Detection And Source Separation In Simulated Brain Computer Interface Systems, Muhammad Asim Mubeen Jan 2016

Bayesian Signal Detection And Source Separation In Simulated Brain Computer Interface Systems, Muhammad Asim Mubeen

Legacy Theses & Dissertations (2009 - 2024)

The problems of signal detection and source separation are important in many fields of science and engineering. In many cases, a target signal needs to be detected in real time and is contaminated by noise. Sometimes the level of noise is on the order of the signal itself. The real time detection of a target signal is of key importance in problems such as the brain computer interface systems. In brain computer interface systems, the neural activity (electric signals) of the brain is detected using sensors (electrodes) on the surface of the brain or the scalp. This signal is contaminated …


Probing Secondary And Tertiary Rna Folding Using Force And Temperature, William Stephenson Jan 2014

Probing Secondary And Tertiary Rna Folding Using Force And Temperature, William Stephenson

Legacy Theses & Dissertations (2009 - 2024)

RNA folding is the process whereby a single stranded RNA molecule assumes its three-dimensional functional conformation. Along with the protein folding problem, the RNA folding problem remains as one of the great unsolved problems in biophysics. Generally RNA folding occurs in a hierarchical manner whereby the sequence of an RNA (primary structure) determines which regions will form helical segments (secondary structure) before further rearrangement and base pairing of secondary structure motifs (tertiary structure). Due to the intimate connection between structure and function within molecular biology, increased familiarity with the thermodynamic and kinetic factors that govern RNA folding will permit the …
