Palladium assisted ring closures
The carbopalladation process has been extended to form carbocyclic systems. The intramolecular version of the carbopalladation process stereospecifically generates fused bicyclic palladium complexes upon treatment of cis and trans methyl-S-methyl-2-carbomethoxy-7-thio-hept-5-en-l-oate with lithium …

Algebraic closures in complexity theory
We use algebraic closures and structures which are derived from these in complexity theory. We classify problems with Boolean circuits and Boolean constraints according to their complexity. We transfer algebraic structures to structural complexity. We use the generation problem to classify …

THE LOCAL EFFECT OF COLLEGE CLOSURES
… impact, the absence of colleges due to their closures is expected to have local ramifications; nonetheless, comprehensive empirical evidence on the local effect of college closures is currently lacking. To address this gap, I leverage synthetic control methods to examine the effect that …

Geometric complexity theory and orbit closures of homogeneous forms
… techniques to classify the boundary of orbit closures in the general case. We can successfully give a description for the 3×3 determinant polynomial and under one remaining assumption, also for the general binomial. We also determine the stabilizer group of the determinant of a generic …

Real-time automatic machine inspection of plastic bottle closures
… an automatic system for plastic bottle closures. These plastic closures ae manufactured at 20 per second and the inspection must be done in real-time at this rate. Two types of defects must be detected and the defective closures removed from the production line. Inspection by human …

Numerical Analysis for Data-Driven Reduced Order Model Closures
This dissertation contains work that addresses both theoretical and numerical aspects of reduced order models (ROMs). In an under-resolved regime, the classical Galerkin reduced order model (G-ROM) fails to yield accurate approximations. Thus, we propose a new ROM, the data-driven variational …

Optimizing the closures development process using the design structure matrix
… generate non-linear feedback. An analysis of the closures product and process development tasks at a major US automaker prompted the creation of new tools to optimize the ordering, identification of coupled blocks, prioritization of interactions, allocation of resources, and modeling of multiple …

Machine learning non-local closures for turbulent anisotropic multiphase flows
In this thesis we formulate a data-driven, nonlocal closure scheme for turbulent multiphase fluid flows. In more detail, we use the predictions of neural nets to actively integrate in time the evolution of a turbulent anisotropic fluid flow on which bubbles that act as passive inertial tracers are …

Mean reaction rate closures for nanoparticle formation in turbulent reacting flow
This thesis investigates mean reaction rate closures for turbulent reacting flow. The closures model the mean rate of reaction in the flow and are applied to simulations of nanoparticle formation. The simulations couple detailed chemical reaction, particle population dynamics and turbulent flow, …

Percolation in Two-Dimensional Grain Boundary Structures and Polycrystal Property Closures
… the method is found to be reasonable for finding closures in the test case. Other general optimization techniques for the form of the problem in-hand are explored for completeness of the study. These include a survey of unconstrained techniques that might be useful in large-scale problems, and an …

The Effectiveness of Periodically-Harvested Closures in Meeting Ecological and Socioeconomic Objectives
<p>Periodically-harvested fisheries closures (PHCs) are a widespread form of community-based marine spatial management used throughout the Indo-Pacific that also is currently being intensively advocated by conservation organizations for supporting productive fisheries and healthy marine ecosystems. …

Elliptical Rolling Link Toggle Mechanisms for Passive Force Closures with Self-Adjustment

California Charter School Closures: Perspectives and Advice from Nine Former Charter School Directors
… has been very little research on charter school closures. This qualitative study attempted to (a) determine which types of California charter schools have closed, (b) discover the reasons the schools' former leaders give for the closures, as well as compare official reasons for closure with the …

An assessment of the quantum for financial provision of mine closures: a Monte Carlo approach.
Poor mine closure policy threatens both society and the environment. Some of the more prominent threats that have manifested are acid mine drainage, slimes dams and toxic dust from dumps. Current legislation requires that new mines set aside funds to cover their rehabilitation costs at closure.
