At the Summer Solstice

Meridional variations of temperature, C2H2 and C2H6 abundances in Saturn’s stratosphere at southern summer solstice

Measurements of the vertical and latitudinal variations of temperature and C2H2 and C2H6 abundances in the stratosphere of Saturn can be used as stringent constraints on seasonal climate models, photochemical models, and dynamics. The summertime photochemical loss timescale for C2H6 in Saturn’s middle and lower stratosphere (∼40–10,000 years, depending on altitude and latitude) is much greater ...

Water vapor map of Mars near summer solstice using ground-based infrared spectroscopy

Ground-based spatial mapping of Mars provides a unique way to retrieve the global distribution of minor atmospheric species and to study transient phenomena or possible variations with the local hour. We have obtained an instantaneous map of water vapor on Mars near summer solstice (Ls = 80◦) using the Texas Echelon Cross Echelle Spectrograph (TEXES) at the NASA Infrared Telescope Facility (IRT...

Sparse Days and ANR SOLSTICE

Jeffrey Hyman’s Summer Research at UCLA

We examine three Monte Carlo sampling methods on idealized examples. Implementing the Metropolis algorithm on created functions, we compare the single temperature to four temperatures running in parallel. Using simulated annealing and parallel tempering on the traveling salesman problem, we examine what each of the methods is capable of exploring. We focus specifically on parallel tempering’s a...

GripFab: Summer Research Experience at UMBC

The influx of consumer-grade 3D printers has changed the potential user base for computer-aided drafting (CAD) software. No longer are 3D models solely the work of engineers and animators. We now see hobbyists, educators, and even children generating 3D-printed objects, however, there is a significant skill gap between the novice 3D printer user and the expert designer. Filling that gap is a gr...
