"Fragile bilinguals: rescaling ""good"" and ""bad"" South Korean bilinguals"
My dissertation explores how U.S.-based multilingual South Korean speakers of English and Korean negotiate their positions in the over-crowded and complex lingusitic market, and try to stake a claim to being legitimate bilinguals through the process of metapragmatic typification (Agha, 2007). …

Rescaling the State: The Politics of Educational Decentralization in Catalonia
This dissertation examines the processes surrounding educational policy production through an exploration of the shifting policies of educational decentralization in Catalonia, Spain. It provides an account of the ways in which these policies are articulated and rearticulated through Catalonia's …

Rescaling space, recapturing power : the role of Russia's Federal Districts in Putin's recentralizing project
… examination of the Federal Districts is that of rescaling. In brief, rescaling posits that a state's spatial organization is a key factor that influences-and is itself influenced by-the administrative level of authority (e.g. national, regional, local) at which a state's political power is …

Rescaling Capital: The Potential of Small-Scale and Mass-Produced Physical Capital in the Energy and Materials Processing Industries
Observing the evolution of size of physical capital in fundamental infrastructure and processing industries such as energy, mining, and chemical processing, etc, over the last century suggests the prevalence of an unambiguous mantra -- "bigger-is-better." This dissertation questions some of the …

Algorithms and inference for simultaneous-event multivariate point-process, with applications to neural data
… an SEMPP, which leads to new thinning and time-rescaling algorithms for simulating an SEMPP stochastic process. Starting from the likelihood of a discrete-time form of the disjoint representation, we present derivations of the continuous likelihoods of the disjoint and MkPP representations of …

Semiclassical spectral analysis of discrete Witten Laplacians
… integer lattice is considered. After rescaling of the operator and the lattice size we analyze the tunnel effect between different wells, providing sharp asymptotics of the low-lying spectrum. Our proof, inspired by work of B. Helffer, M. Klein and F. Nier in continuous setting, is …

Nonperturbative renormalization in classical φ4 theory
… A variety of techniques are used including a rescaling of a nonlinear complete basis, a limit of finite periodic systems, and an analytic calculation of RG equations using a limit of finite systems. Assuming that the truncated forms of the action employed do not change the physics and that …

Single-degree-of-freedom energy harvesters by stochastic excitation
… invariant with respect to magnitude or temporal rescaling of the input spectrum and they depend only on the relative distribution of energy across different harmonics of the excitation. We then compare three different classes of linear and nonlinear oscillators and using stochastic analysis tools …

G-Frobenius manifolds
… contains a G-Frobenius manifold up to a rescaling of its metric. Finally, we specialize to the case of G = Z/2Z and prove the structure theorem for (pre-)Z/2Z-Frobenius manifolds. We also construct an example of a Z/2Z-Frobenius manifold using this theorem, that arises in singularity …

A generalized approach for calculation of the eigenvector sensitivity for various eigenvector normalizations
… eigenvector sensitivities and the use of rescaling equations.

Unraveling the Geographies of the U.S. Public Education System: An Analysis of Scale, Segregation, and Hegemony
… I show how processes of educational rescaling have helped to resolve large-scale economic crises in every era of American history. Lastly, I argue that for society to change, new scalar configurations need to be made. Taken together, this research project stresses the point that …

Algebraic multigrid for stabilized finite element discretizations of the Navier Stokes equation
… schemes shows that a characteristic length based rescaling of the numerical stabilization is necessary for a consistent multigrid representation.

Experimental Investigations on Multiphase Phenomena in Porous Media
… of air conductivity showed the necessity of a rescaling of the effective air saturation for predictions. The influence of the sample structure on the hydraulic and pneumatic properties was illustrated with several homogenous and heterogeneous samples of repacked sands. The differences between …

Variational data assimilation for two interface problems
… in time. By introducing auxiliary equations, rescaling the optimality system, and employing other subtle analysis skills, we present the finite element convergence estimation for each case with special attention paid to recovering the properties missed in between the continuous and discrete …

Enabling Theoretical Model Based Techniques for Simulating Large Scale Networks
… one simulation framework. We also propose a new rescaling simulation methodology (RSM) to simulate IP networks with TCP and/or UDP traffic for the cases that the behaviors of all the flows should be inspected. The underlying idea of RSM based simulation is to reduce the computation by scaling …

Large-eddy simulation of turbulent wall-pressure fluctuations using the finite element method
… method, a variant of the recycling and rescaling method, is used. In this method, the turbulent velocity profile from a specific plane within the computational domain is recycled and rescaled propriately, and re-introduced at the inlet of the domain at every time step iteration. In the …

Learning under differing training and test distributions
… The integral part of these models are rescaling weights that match the rescaled or resampled training distribution to the test distribution. Integrated models are studied where only one optimization problem needs to be solved for learning under differing distributions. With a two-step …
