Second-Order Algebraic Theories
Second-order universal algebra and second-order equational logic respectively provide a model theory and a formal deductive system for languages with variable binding and parameterised metavariables. This dissertation completes the algebraic foundations of second-order languages from the viewpoint …

Second-order finite free probability
… the coefficients of these polynomials, in order to deepen our knowledge of how random characteristic polynomials fluctuate about their expected values. Focusing on a special case related to random unitary matrices, I applied the representation theory of the unitary group to derive a …

Second-Order Relative Motion Equations
This thesis presents an approximate solution of second order relative motion equations. The equations of motion for a Keplerian orbit in spherical coordinates are expanded in Taylor series form using reference conditions consistent with that of a circular orbit. Only terms that are linear or …

Second order nonlinearities in silicon photonics
In this thesis, second order optical nonlinearities in silicon waveguides are studied. At the beginning, the strained silicon platform is investigated in detail. In recent years, second order nonlinearities have been demonstrated on this platform. However, the origin of these nonlinearities was not …

Second Order Logic and Logical Form
… explores several related issues surrounding second order logic. The central problem running throughout is whether second order logic should provide the underlying logic for formalizations of natural language. A prior problem is determining the significance of this choice. Such controversies …

Overall results in second-order elasticity
… large displacements has been adapted so that second-order elastic effects can be included in certain overall quantities such as bending stiffness without explicit determination of the second-order solution. The approach uses Betti's reciprocal theorem. The method is applied to obtain the …

Classification of second-order conformally-superintegrable systems
… in mathematical-physics. Systems with constants second-order in the momenta have been particularly well studied in recent years. This thesis provides a classification of non-degenerate (maximum parameter) three-dimensional second-order superintegrable systems over conformally-flat spaces. I show …

Second order necessary conditions in optimal control
This thesis presents second order necessary conditions for the standard deterministic optimal control problem without conventional regularity assumptions. It reports three different advances in the second-order theory. First, we study conjugate points in smooth optimal control. We describe a set of …

Porphyrins as second order nonlinear optical materials
Because of the unusually high thermal and chemical stability of porphyrins as well as their very large $\pi$-conjugated systems, three classes of high $\beta$-value push-pull porphyrins were synthesized and subsequently successfully engineered into Langmuir-Blodgett (LB) films for a systematic …

Second Order Interactions in Solid State Systems
Non-covalent interatomic interactions, particularly hydrogen bonds, have been studied through systematic analysis of published crystallographic data, and through the determination of novel crystal structures. Chapters 1-3 give relevant background on crystal structure analysis and describe the …

Categorical models of second-order abstract syntax
… with binding. We introduce the familial model of second-order abstract syntax as a categorical foundation for intrinsic typing, and show its equivalence to the presheaf model both syntactically and semantically. This places many ad hoc practices on solid mathematical footing, opening up principled …

Second order error correction in quantum computing
… evaluates a five qubit code for correcting second order bit-flip errors. The code consists of encoding, decoherence, decoding, and error correction steps. This work analyzes the proposed code using geometric algebra methods and examines the state of the system after each step in the process.

Non-Equilibrium Dynamics of Second Order Traffic Models
Even though first order LWR models have many limitations, they are still widely used in many engineering applications. Second-order models, on the other hand, address many of those limitations. Among second-order models, the inhomogeneous Aw-Rascle-Zhang (ARZ) model is well-received as its …
