Abstract:

Approved for public release; distribution is unlimited.<br>We examine the performance of the Yost Engineering Incorporated 3-Space Sensor Data-Logging (TSS-DL) for use in wave resolving drifters (WRDs) that collect ocean surface wave data. We create a surface wave orbital motion simulator to test the TSS-DL in a controlled, laboratory setting at the Naval Postgraduate School. Tests are conducted in three different configurations at five frequencies within the swell and wind-sea bands. Results from the tests show that the TSS-DL can accurately resolve the vertical simulated wave motions to with

Abstract:

Ocean circulation in Greenland's large glacial fjords is one mechanism that controls the rate of submarine melting at the termini of Greenland's outlet glaciers. Here we use hourly position data from GPS units deployed on ten large (>100 meter), deep-keeled icebergs in Sermilik Fjord, SE Greenland. We observe and quantify the motions of these icebergs moving through the mélange, fjord, and shelf regimes. In the mélange, icebergs move outward with glacier flow until pushed loose by large calving events. In the fjord, high frequency, low amplitude tidally-driven motions are superimposed on domin

Being a city in and of crisis, Athens, Greece, undergoes dramatic changes in its spatialities. Amidst severe economic austerity, a new poverty management is being established in the city shaping contested landscapes of homelessness, composed by spatialities of homeless stigma. This dissertation is about these very spatialities and the subjectivities shaped therein. And it poses two parallel, dialogic and inextricable questions under one common question mark: how are the homeless geographies of Athens made and how are homeless subjects made along with these geographies?

Thesis (MPhil)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: In the context of both climate change and peak oil, it is clear that the tourism industry cannot continue with a business-as-usual approach. Unfettered fossil fuel use is no longer an option and novel approaches need to be explored in order to change the configuration of energy systems. Transport is particularly energy intense and consequently, since it involves travel, so is tourism. The Drifters Desert Nature Reserve (DDNR) is probably a net carbon sink.

In order to understand water quality in the coastal ocean and its effects on human health, the necessity arises to locate the sources of contaminants and track their transport throughout the ocean. Dynamical systems methods are applied to the study of transport of enterococci as an indicator of microbial concentration in the vicinity of Hobie Beach, an urban, subtropical beach in Miami, FL that is used for recreation and bathing on a daily basis. Previous studies on water quality have shown that Hobie Beach has high microbial levels despite having no known point source. To investigate the caus

Abstract:

Entrainment velocity, salt flux and the turbulent diffusivity of salt are estimated in the outflow of a small, radially spreading buoyant outflow, just outside of the Teign Estuary mouth, as a means to compare mixing dynamics between very small and larger-scale estuarine and river plumes, and build on a scant knowledge base regarding the former. The analysis was made using a control volume approach, based on the conservation of momentum, volume and salt, from a Lagrangian perspective. Drifting buoys were used to accomplish this. The analysis was based on that employed by McCabe et al. (2008),

Abstract:

The nearshore current field, defined here as the residual horizontal flow after averaging over the incident wave period, exhibits variability at a range of time and space scales. Some of the variable currents are low frequency gravity wave motions. However, variable, rotational (in the sense of possessing vertical vorticity) flow can also exist as part of the overall nearshore current field. A field and numerical modelling investigation of these variable rotational currents has been carried out. Drifters, which were developed for surfzone use, enabled measurement of the nearshore current stru

Une estimation précise de la circulation de surface est cruciale en raison de son impact direct sur les propriétés physiques et bio-géochimiques du du milieu marin. Cependant, l’estimation des courants reste un défi car le champ de circulation est affecté par des flux qui changent rapidement. Ce problème s’accentue en Méditerranée orientale, où les observations in-situ sont relativement rares et où les imprécisions des observations altimétriques augmentent. Par conséquent, certaines des caractéristiques de méso-échelle sont encore débattues ou inconnues, en particulier dans le bassin levantin.

From the position data of 23 drifters over the four years period, 1982 to 1985, the upper layer kinematics of the Northeast Pacific were investigated. The focus of this study was upon the topographic influence, wind forcing, and Rossby waves. The notions of homogeneity and stationarity were applied to both the Eulerian and Lagrangian analysis. A new computational scheme was proposed and tested in order to explicitly take into account the Lagrangian characteristics of the drifter data. The Eulerian analysis showed that the spatial and temporal distributions of the mean current and the mean wind

Abstract:

By utilising new measurement technologies and advances in numerical models, especially through the use of open-source software, this project paves a way for the better understanding of estuarine hydrodynamics. Using state-of-the-art GPS-tracked drifters and an ensemble-based data assimilation approach, this research presents several novel methods to improve the accuracy of hydrodynamic models for shallow estuaries. It opens new opportunities for researchers/engineers to use Lagrangian data to better employ hydrodynamic models to understand real-time and future estuarine dynamics.

Abstract:

It is possible to reduce residual and maximum drifts in buildings by adding “elastic stories” that engage gravity columns in seismic response. An elastic story is a story wherein the buckling restrained brace frame (BRBF) size is increased to prevent yielding when an earthquake occurs. Buildings ranging from 4–16 stories were designed with various elastic story brace sizes and locations to determine the optimal combination to best reduce drifts. Gravity column stiffnesses were also varied in elastic story buildings to determine the effects on drifts. Computer models were used to analyze these

We used data from 1998 to 2014 to derive these climatological values in bimonthly bins from 150 km to 600 km.

Abstract:

Denna magisteruppsats beskriver framtagande och utveckling av riktlinjer för ett system vars mål är att förändra och förbättra en organisation, där arbetet idag utgår ifrån en stationär plats men där vi hävdar att arbetssättet skulle kunna vara helt mobilt. I uppsatsen beskriver och diskuterar vi vårt tillvägagångssätt, resultatet av fältstudier och analys samt en diskussion som behandlar konstruktionen av ett mobilt anpassningsbart system. Uppsatsen resulterar i framtagandet av designriktlinjer för en mobil artefakt. Denna artefakt ska kunna stödja det arbete som utförs av personalen som arbe

Abstract:

Cette thèse porte sur l'hydrogénation en phase gazeuse du furfural sur des oxydes de fer et de magnésium. De nombreux catalyseurs avec différents ratio molaires en fer et magnésium ont été préparés par des méthodes de co-précipitation ou d'imprégnation. Ils ont été ensuite testés lors de la réduction du furfural (FU) en utilisant du méthanol comme donneur d'hydrogène. L'alcool furfurylique (FAL) et le 2-methyl furfural (MFU) étaient les principaux produits obtenus démontrant alors que les systèmes Mg/Fe/O peuvent favoriser les réactions d'hydrogénation séquentielles et d'hydrogénolyse.

Abstract:

Syftet med den här uppsatsen är att undersöka biblioteket Kinderbücherei Bahrenfeld BüBa och sättet de bedriver sin verksamhet. Jag vill undersöka hur det faktum att biblioteket är föreningsdrivet med all personal på volontärbasis påverkar hur biblioteket fungerar och styrs. Den metod som jag använt för studien är kvalitativa intervjuer. Mitt fokus i studien ligger på hur arbetet fungerar och hur organisationsformen påverkar hur personalen upplever sitt arbete. Jag vill också ta reda på om Kinderbücherei Bahrenfeld BüBa lyckas väl med sitt uppdrag att bedriva biblioteksverksamhet. Syftet med s

Abstract:

In this paper, we consider families of time Markov fields (or reciprocal classes) which have the same bridges as a Brownian diffusion. We characterize each class as the set of solutions of an integration by parts formula on the space of continuous paths C[0; 1]; R-d) Our techniques provide a characterization of gradient diffusions by a duality formula and, in case of reversibility, a generalization of a result of Kolmogorov.
