An analysis of large-area CO J=3-2 maps from the James Clerk Maxwell Telescope for 12 nearby spiral galaxies reveals low velocity dispersions in the molecular component of the interstellar medium. The three lowest luminosity galaxies show a relatively flat velocity dispersion as a function of radius while the remaining nine galaxies show a central peak with a radial fall-off within 0.2 − 0.4r25...
We deal with strong density results of smooth maps between two manifolds X and Y in the fractional spaces given by the traces of Sobolev maps in W .
We present new Hα Fabry-Perot observations of the HH 1/2 system. Line profiles, barycenter radial velocity maps and dispersion maps are derived from the channel maps of HH 1 and HH 2. The radial velocity barycenter maps of both HH 1/2 show a general trend of “red-shifted upstream/blue-shifted downstream” pattern. A “direct+scattered” component model for three emitting condensations is qualitati...
The navigation problem is classically approached in two steps: an exploration step, where mapinformation about the environment is gathered; and an exploitation step, where this information is used to navigate efficiently. Deep reinforcement learning (DRL) algorithms, alternatively, approach the problem of navigation in an end-to-end fashion. Inspired by the classical approach, we ask whether DR...
One method commonly used by computer architects to study application memory behavior is trace driven simulation of synthetic address traces. Leveraging synthetic traces reduces the time needed to gather the diverse set of application traces needed for effective testing, and provides programmers with knowledge to tune their programs for better runtime performance. In this paper, we present a tec...
Under certain theoretical assumptions, the theory of seismic interferometry allows the construction of artificial (or virtual) sources and receivers at the locations of receivers in a physical experiment. This is done by redatuming the physical sources to be at the locations of the physical receivers. Each redatumed trace is formed by stacking the cross-correlations of appropriate recorded trac...
This thesis studies event monitoring techniques that are used for collecting, filtering and visualising event traces from parallel programs. Implementations of two experimental monitoring systems are presented. The first system is a hybrid implementation which uses extra hardware to collect event traces. The second system is a software implementation which was implemented on the Edinburgh Concu...
Cryo-electron microscopy (cryo-EM) has produced density maps of various resolutions. Although α-helices can be detected from density maps at 5-8 Å resolutions, β-strands are challenging to detect at such density maps due to close-spacing of β-strands. The variety of shapes of β-sheets adds the complexity of β-strands detection from density maps. We propose a new approach to model traces of β-st...
