Stability of flat galaxies
… and properties of stationary solutions of the flat Vlasov-Poisson system. This system of partial differential equations can be used as a model of extremely flat astronomical objects and is a combination between the two-dimensional motion of particles and the three-dimensional interaction …

Length functions in flat metrics
This dissertation is concerned with equivalence relations on homotopy classes of curves coming from various spaces of at metrics on a genus g >1 surface. We prove an analog of a result of Randol (building on work of Horowitz) for subfamilies of at metrics coming from q-di erentials. In addition we …

Electrical impedance of methane flat flame
… of the complex electrical impedance of a Methane Flat Flame Burner. The data shows a relationship between the magnitude of the impedance and temperature, which relates directly to the fuel/air mixture. This work was supported in part by the National Energy Technology Laboratory (NETL).

Conformally Flat Spaces of Bounded Curvature
Here we show that if the logarithm of the conformal factor is subharmonic then the space has curvature bounded above by zero, and, subject to a growth constraint, if the logarithm of the conformal factor is subharmonic under all conformal transformations then the curvature is bounded below by zero. …

Selmer groups as flat cohomology groups
… In the course of the argument we describe the flat cohomology group ... of the ring of integers of K with coefficients in the pm- torsion A[pm] of the Neron model of A by local conditions for p V E, compare them with the local conditions defining Selm 2A, and prove that A[p't ] itself is …

On Gorenstein Projective and Gorenstein Flat Modules
Purpose: H. Holm's metatheorem states, "Every result in classical homological algebra has a counterpart in Gorenstein homological algebra". We support this statement by showing over commutative Noetherian rings of finite Krull dimension, every Gorenstein at module has finite Gorenstein projective …

Chamber Music for the E-Flat Clarinet
… involving up to 12 players which include the E-flat soprano clarinet. Doubling parts, defined as B-flat and E-flat clarinet on one part for one performer, will be included only if the E-flat clarinet is present for one or more entire movements. The intent is to show that this lesser-known …

Bootstrap Techniques in Flat Space and Cosmology
… the context of the Effective Field Theory of inflation. I extend flat spacetime bootstrap methods to settings where the boost symmetry is violated. I also employ several well-known cosmological bootstrap methods to constrain graviton correlators at the end of inflation.

Horizontal non-contact slumping of flat glass
… [mu]m, 36±2.5 pm, and 30.5±2.5 [mu]m. The best flatness achieved was 6.7/3.6+0.5 [mu]m for front/back of the glass sheet, with a gap of 36+2.5 [mu]pm. It was discovered that 600*C is hotter than necessary and that 550*C is still too hot for optimal slumping conditions. In addition, an important …

Perception-aware planning for differentially flat robots
The central question to this thesis can be stated as follows: “Can we design computationally efficient algorithms that are capable of robustly navigating complex environments and unstructured environments at operational speeds." Visual inertial navigation in perceptually degraded environments is a …

Edge-unfolding almost-flat convex polyhedral terrains
In this thesis we consider the centuries-old question of edge-unfolding convex polyhedra, focusing specifically on edge-unfoldability of convex polyhedral terrain which are "almost at" in that they have very small height. We demonstrate how to determine whether cut-trees of such almost-at terrains …

2d dose measurement using a flat panel EPID
… routine. The intrinsic build-up of the flat panel EPID was found to be 1.1 cm of water equivalent material. The response of the flat panel EPID was found to be linear between 0 and 300 cGy. To calibrate the flat panel EPID for two dimensional dose measurements, the deconvolution method …
