The blowup formula for higher rank Donaldson invariants
… a smooth 4-manifold X and the invariants of its blowup X#CP2 . This relationship can be expressed in terms of a formal power series in several variables, called the blowup function. I compute the restriction of the blowup function to one of its variables, by solving a special system of ordinary …

Well-posedness and blowup results for the swirl-free and axisymmetric primitive equations in a cylinder
… this thesis discusses the problem of finite-time blowup of the solution of the system of equations. Following a part of the method introduced by Wong in Proc Am Math Soc. 143 (2015), we prove that the first derivative of the radial velocity blows up in time, using primary functional analysis tools …

Oblivious RAM : from theory to practice
… operation must incur a client-storage bandwidth blowup that is logarithmic in the dataset size, which can translate to > 100x in practice. We address this challenge by developing new tools for constructing ORAMs that allow us to achieve constant bandwidth blowup while requiring only small client …

Asymptotic description of the formation of black holes from short-pulse data
… solution metric and use the technique of real blowup to propose a desingularized manifold and an associated rescaled tangent bundle (which we call the "short-pulse tangent bundle") on which the putative solution remains regular. We prove the existence of a solution solving the vacuum Einstein …

Asymptotic behavior of the solutions to a family of PDE's arising from the chemotaxis equations of Keller and Segal
… (2005), pp. 361--364] to analyze the finite time blowup case. Some numerical results are provided to back up the analysis. Some questions and directions for future study are posed.</p>

Continuation Stealing in Julia
… tasks across multiple processors. Memory blowup from scheduling a program with work stealing can be bounded by using continuation stealing when new tasks are spawned. Continuation stealing is opposed to child stealing, a different method for spawning tasks that is simpler to implement, but …

Existence and Regularity of Solutions to Some Singular Parabolic Systems
… some tools that showed the boundedness or blowup of solutions to a semilinear parabolic system with homogeneous Neumann boundary conditions. This system, the so called ’Activator-Inhibitor Model’, is of interest as it is used to model biological processes and pattern formation. Similar …

Analysis and Mitigation of Multiple Radiation Induced Errors in Modern Circuits
… time consuming or can encounter memory blowup. To solve this issue, a simulation tool is proposed which employs partitioning to reduce the execution time and memory overhead. In addition, the tool integrates an accurate electrical masking model. Compared to existing simulation tools, the …

Results in Extremal Graph Theory, Ramsey Theory and Additive Combinatorics
… its blow-up. We prove the conjecture for the 2-blowup of C_6. In Chapter 4 we study a coloured variant of the Turán problem. The rainbow Turán number of H, denoted by ex*(n,H), is the maximum possible number of edges in an n-vertex properly edge-coloured graph without a rainbow subgraph …
