Lipschitz homotopies of mappings from 3-sphere to 2-sphere
This work focuses on important step in quantitative topology: given homotopic mappings from S^m to S^n of Lipschitz constant L, build the (asymptotically) simplest homotopy between them (meaning having the least Lipschitz constant). The present paper resolves this problem for the first case where …

Sphere of Influence
The following thesis titled SPHERE OF INFLUENCE is about development. I discuss my efforts to develop as an artist addressing observation and awareness of the self and our surroundings. I will discuss how this relates to my approach with materials and process and will explain not only what the …

Effect of gap lenghts of sphere-sphere electrodes on air breakdown level under lightning impulse
Impinging jets are a best method of achieving particularly high heat transfer coefficient and are therefore employed in many engineering applications. In this study we seek to understand the mechanism of the distributed heat on the curve surface with the goal of identifying preferred methods to …

The design of adjustable spherical mechanisms using plane-to-sphere and sphere-to-plane projections
… the coordinates of a given planar mechanism on a sphere using the method introduced in this work, the user can design both planar and spherical mechanisms respectively. This research introduces sphere-to-plane and plane-to-sphere projection methods with optimization methods to minimize the …

Nuclear magnetic resonance investigation of mineral surface reactions involving inner-sphere and outer-sphere complexes
… Phosphate and Cs are good examples of inner-sphere and outer-sphere complexes, respectively, and this study shows that NMR is in many ways a more useful tool to investigate surface adsorbed species than other spectroscopic methods. Chapter 1 reviews mineral surface reactions which involve …

Computer simulation of rod-sphere mixtures.
… particles with an aspect ratio of 3:1 and hard spheres with diameters equal to the breadth of the rods is simulated at various sphere concentrations. Both mixing-demixing and isotropic-nematic transition are studied using Monte Carlo techniques. Secondly, the effect of adding Lennard-Jones …

Gender, discourse and the public sphere
… the roles they are assigned within the public sphere.</p> <p>With reference to selective transcripts of in-depth structured interviews with women in each of the domains under investigation, I suggest that the complex negotiations in which they engage in order to manage contradictory …

Polymer and sphere diffusion in confinement
… to study the diffusion of both colloidal spheres and polymers in slit microchannels. The molecules are allowed to sample the entire height of the microchannel. We find that the sphere data agrees well with a gap-averaged Oseen linear superposition approximation even at very high …

Random Sphere Packing Model of Heterogeneous Propellants
In addition, a method of analysis of the morphology of heterogeneous propellants is developed which uses the concept of multi-point correlation functions. A set of intrinsic length scales of local density fluctuations in random heterogeneous propellants is identified by performing a Monte-Carlo …

Molecular control of interfacial inner-sphere electron
The interconversion of electrical and chemical energy relies on the intimate coupling of protons and electrons to activate small molecules including 02, C0 2, and H20. The mechanistic pathways governing the proton- and electron-transfer steps are key to the efficiency of catalysis because they …

Dementia within the Marital Sphere - Discourse, Power & Knowledge
… to be complimentary in making marriage a natural sphere for caring. Biomedical discourse on dementia was effective in self-management of dementia ‘signs’ and electing ‘ethically bound’ spousal support, effective as a modern form of power where there are limited societal resources.
