Quantum Toroidal Superalgebras
We introduce the quantum toroidal superalgebra E(m|n) associated with the Lie superalgebra gl(m|n) and initiate its study. For each choice of parity "s" of gl(m|n), a corresponding quantum toroidal superalgebra E(s) is defined. To show that all such superalgebras are isomorphic, an action of the …

Einstein constraints gluing and toroidal cusps
… adapted in an attempt to create a gluing along toroidal cusps. The relevant differences and obstacles for this new gluing are discussed, restricting to the case of compact 3-manifolds and with a focus on the conformal vector Laplacian on toroidal cusps.

(MEMS) toroidal magnetics for integrated power electronics
… analysis, optimization, and design of air-core toroidal inductors for integration into high-efficiency, high-frequency power electronic circuits. The first part of the thesis presents the derivation of models for stored energy, resistance and parasitic capacitance of microfabricated toroidal …

Comparative Analysis of Electrodynamic Toroidal Radiation Shielding Configurations
… the performance of specific configurations of toroidal superconducting solenoids to generate magnetic fields that deflect incoming energetic protons via the Lorentz force. Bulk material shielding configurations using various thicknesses of liquid water are similarly investigated, as are …

On the (Co)Homology of Non-Commutative Toroidal Orbifold
… In this thesis, we study noncommutative toroidal orbifolds generated by actions of finite subgroups of <em>S L</em>(2,) on a noncommutative torus algebra.</p> <p>In the first part, we calculate the Hochschild and cyclic homology of Γ for all finite subgroups Γ <em>S</em> L(2,). In the …

Toroidal Matrix Links: Local Matrix Homotopies and Soft Tori
… -> M_n <- C([-1, 1]^N) using the so called toroidal matrix links, which can be interpreted as normal contractive matrix analogies of free homotopies in algebraic topology. In order to deal with the locality constraints, we have combined some techniques introduced in this document with …

Magnetic and Toroidal Symmetry of Lithium Transition Metal Orthophosphates
… a detailed methodology for determining the toroidal structure which would result for the magnetic structure in candidate ferrotoroidal materials. The model provides a method for determining how many toroidal moments would be present, where they would be located within the unit cell, and …

Scheduling algorithms to improve utilization in toroidal-interconnected systems
… parallel cellular architecture system with a toroidal inter-connect, currently being developed at the IBM T.J.Watson Research Center. Cellular architectures with a toroidal interconnect are effective at producing highly scalable computing systems, but typically require job partitions to be …

Free vibration and stability of complete orthotropic circular toroidal shells
… analysis of complete orthotropic circular toroidal shells. It is conducted in four main parts. A literature survey is first carried out indicating the new and continuing uses of toroidal shells in engineering structures. Secondly, theory is developed for the free vibration analysis of …

Electron Bernstein wave current drive modeling in toroidal plasma confinement
… a fusion reactor requires non-inductively driven toroidal currents. Radio frequency waves in the electron cyclotron (EC) range of frequencies can drive localized currents and are thus particularly attractive for control of the current profile. In the high-[beta] regimes of spherical tokamaks (ST) …
