Genl S G (Manie) Maritz se aandeel aan die rebellie van 1914 -1915
… en impulsief, sou die daaropvolgende gebeure hom opnuut, soos 14 jaar te vore, in die vuurproef plaas. Na die Vrede van Vereeniging het Maritz geweier om Britse onderdaan te word en wyk uit na Angola en Europa. In 1912, ses jaar na sy terugkeer, word hy rnajoor in die pasgestigte …

Photonic band gap structures for superconducting radio-frequency particle accelerators
… unwanted Higher-Order electromagnetic Modes (HOMs) in the structure. Strong HOM damping is highly desirable for SRF cavities because it increases maximum achievable beam current by reducing the negative effect that HOMs have on the propagating electron beam. In the presented structure, …

Imagined communities, divided realities : engaging the apartheid past through 'healing of memories' in a post-TRC South Africa
… process and effects of the Healing of Memories (HOM) project in Cape Town. HOM is a civil society initiative established in 1996 to facilitate storytelling workshops between South Africans, previously divided on the basis of race and class. Critiquing reconciliation discourses in South Africa, in …

Experimental studies of multipass beam breakup and energy recovery using the CEBAF injector LINAC
… high Q of the cavity higher-order modes (HOMs ). The CEBAF accelerator, which employs five pass recirculation through two superconducting linacs to accelerate high CW current (up to 200 pA), poses unique instability problems. An experimental investigation of multipass BBU at CEBAF has been …

Trace Diagrams, Representations, and Low-Dimensional Topology
… pi is a free group. Then the coordinate ring C[Hom(pi,G)] of the homomorphisms from pi to G is isomorphic to C[G^r]=C[G]^{tensor r} for some r>=0. The coordinate ring C[G] may be identified with the ring of matrix coefficients of the maximal compact subgroup of G. Therefore, the coordinate ring …

High-quality source of fiber-coupled polarization-entangled photons at 1.56 [mu]m
… quantum phenomena such as the Hong-Ou-Mandel (HOM) dip, the collapse of a Bell state due to measurement, or the Clauser-Horne-Shimony-Holt (CHSH) inequality violation in a single experimental setup. An HOM dip with a two-photon quantum interference visibility of 80% was demonstrated.

Mixing of nanosize particles by magnetically assisted impaction techniques
… loss in surface area, but in order to obtain homogeneous mixing, de-agglomeration of the individual nanoparticle constituents is necessary. Due to high surface area, nano-particles form very large, fractal agglomerates. The structure of these agglomerates can have a large agglomerate composed …

Turnover Intentions and Turnover: The Moderating Role of Dispositional Affectivity
… with severe consequences for individuals (Hom & Griffeth, 1995). Because turnover intentions are the best predictor of turnover (Griffeth, Hom, & Gaertner, 2000), our ability to explain and predict individual voluntary turnover decisions depends upon our understanding of the …

Experimental study of photonic band gap accelerator structures
… structure. Major advances in higher order mode (HOM) damping are required for the next generation of TeV linear colliders. In this work, PBG HOMs are studied theoretically and experimentally for the first time. PBG HOMs are shown in simulation to be low Q lattice modes, removed from the cavity …

Desinfecção de águas contaminadas com Pseudomonas aeruginosa empregando Processo de Oxidação Avançada (UVC/H2O2): desenvolvimento e modelagem
… que melhor representou o processo foi o de Hom por possuir um termo associado à não-linearidade com relação ao tempo de irradiação. A eficiência alcançada utilizando-se H2O2 como agente oxidante e a taxa de inativação bacteriana dependeu diretamente da concentração inicial de H2O2, atingindo …

Mode conversation losses in overmolded millimeter wave transmission lines
… considered the problem of higher order modes (HOMs) mixed with an HE11 input entering the miter bend. Using a numerical technique, we found that the loss through the miter bend is dependent on both the amplitude of the HOM content as well as its phase relative to the phase of the HE11 mode. …

Coherence, Dephasing, and Quantum Interference in Colloidal Perovskite Nanocrystals
… This thesis chronicles measuring Hong-Ou-Mandel (HOM) two-photon interference, the ubiquitous measure of quantum interference, showing HOM visibilities in colloidal materials for the first time. I also detail what types of experiments and further work can be done to build on what we know now, and …

Spaces of homomorphisms and group cohomology
In this work we study the space of group homomorphisms Hom(Γ,G) from a geometric and simplicial point of view. The case in which the source group is a free abelian group of rank n is studied in more detail since this space can be identified with the space of commuting n-tuples of elements from G. …
