Infinity songs
Infinity Songs is a work for soprano, narrator, mixed ensemble and electronics that explores the life cycle of a star. Each of the work’s four movements depicts a different stage of the star’s life, including how new stars are born from the remnants of previous stars. The piece was written for Leah …

Infinity and experience
This dissertation explores the relationship between our experience and knowledge of the infinite. The first chapter is a critical examination of Shaughan Lavine's project in Understanding the Infinite. Lavine argues that although we do not experience the infinite, we can explain how we acquire …

Equivariant E-infinity algebras
The equivariant 𝔼∞G operad has the property that 𝔼∞G(n) is the total space for the G-equivariant universal principal Σn bundle. There is a forgetful functor from 𝔼∞G-algebras to 𝔼∞-algebras, where 𝔼∞ is the classic 𝔼∞ operad. This functor admits a homotopical right adjoint R. The goal of this …

The robustness of H-infinity control
… a statement that the controllers generated by H-infinity design methods are fragile. A norm was introduced called the parametric stability margin, to serve as a measure of this robustness. A fragile controller is defined as a controller that is very sensitive to changes in its controller …

Stability and distributivity over orbital [infinity]-categories/
… thesis we develop a characterization of the [infinity]-category of G-spectra and of its multiplicative structure in term of the behaviour with respect to equivariant colimits. This will allow us to give an alternative construction of the norm map.

Quantifier rank spectrum of L-infinity-omega
In Part A we will study the quantifier rank spectrum of sentences of L!1,!. We will show that there are scattered sentences with models of arbitrarily high but bounded quantifier rank. We will also consider the case of weakly scattered and almost scattered sentences, and we will make some …

Neutral point inverter controller using H infinity techniques
… leg and a split dc link. In this project, a H infinity (H∞ ) current controller is proposed to force the current flowing through the split dc link to be nearly zero so that the neutral-point current is stable, and then, a current control loop is added to eliminate the imbalance of the current …

Facing infinity in model checking expressive specification languages
Society relies on increasingly complex software and hardware systems, hence techniques capable of proving that they behave as expected are of great and growing interest. Formal verification procedures employ mathematically sound reasoning to address this need. This thesis proposes novel techniques …

On Applications of Resonances, from One to Infinity
… of resonances, with numbers ranging “from one to infinity.” First, we derive single-frequency bounds for the surface-enhanced Raman scattering (SERS) where resonant nanostructures are used to enhance the Raman signal. These bounds are shape independent and only function of the material constants …

Generalized Polynomial H(infinity) Predictive Control Utilizing Minimax Prediction
Due to increased interest in the development and implementation of control schemes which are inherently robust, H$\sb\infty$ optimal control methods are the focus of a great deal of study in the current literature. Industry, however, has been slow in adopting these methods because of the …

Robust regulation with H(2) or H(infinity) performance
In this thesis, three performance problems in linear control systems are studied. Robust regulation against steps and sinusoids is the first. Major results on this classic problem are rederived using only basic state-space ideas.

H-Infinity Norm Calculation via a State Space Formulation
There is much interest in the design of feedback controllers for linear systems that minimize the H-infty norm of a specific closed-loop transfer function. The H-infty optimization problem initiated by Zames (1981), \\cite{zames1981feedback}, has received a lot of interest since its formulation. In …

The User Experience of Disney Infinity: Do Smart Toys Matter?
… involved with the commercial video game Disney Infinity (2.0 Edition), and sought to determine if the unique combination between sandbox and smart toy based gameplay present in gameplay offers an additional level of immersion. This study analyzed the effect of Disney Infinity (2.0 Edition) on …
