Learning to Trade Off Performance and Safety in Mixed Autonomy Traffic
… seen potential for direct optimization of singular system objectives, such as traffic smoothing and emission reduction, and introduces a reinforcement learning-based methodological framework to facilitate a study of the trade offs between performance and safety at a fleet level. This …

High Initial Tones and Plateaux in Spanish and Portuguese Neutral Declaratives: Consequences to the Relevance of F0, Duration and Vowel Quality as Stress Correlates
… Portuguese presents a more complex intonational system than Spanish in declaratives sentence initial position. Results suggest that pitch in Brazilian Portuguese sentence initial position not only express lexical stress, but phrasal tones as well. According to these results the phrasal tones in …

Finite element analysis of 3D electric machine problems
… two possible solutions. One is to solve the singular system directly by using an iterative solver. Another is to regularize the singular matrix with tree-cotree splitting. An algorithm of finding the minimum spanning tree is given. The two solutions have different effects on the convergence …

Networks in nature: applying cultural ecology for stewardship
… is to describe the historical context and systemic structure of the Western agrarian estate model to locate opportunities for strategic solutions to environmental degradation in a way that balances cultivated and conserved natural resources. In part 1, landholders are identified as a point …

Structural decomposition of general singular linear systems and its applications
Singular systems can be found in many real life problems, such as economic systems, biological systems, engineering systems and social systems, to name a few. In this thesis, we aim to exploit the philosophy and development of a powerful structural decomposition technique, which is capable of …

Sound field reproduction
… whose density is to be determined. The singular value decomposition of the integral operator involved is proposed as a method for solving the inverse problem. Closed form expressions are derived for the singular system for the<br/>cases of secondary sources arranged on a sphere and on a …

Asymptotic expansions and stability of hybrid systems with two-time scales
… dissertation, we consider solutions of hybrid systems in which both continuous dynamics and discrete events coexists. One</p> <p>of the main ingredients of our models is the two-time-scale formulation. Under broad conditions, asymptotic expansions are developed for the solutions of the systems …

Heterogeneous chemistry of HONO and surface exchange
… to extract correlations on other timescales. Singular System Analysis, a tool for time series analysis, has been applied successfully to remove diurnal variations and long-term trends from the HONO and RH time series. Correlations of the higher frequency contributions of the remaining signals …
