This thesis outlines the changing landscape of moving image archives in light of the emergence of new media. Whereas, in the twentieth century, these archives were once responsible for the preservation of endangered films and television programs, I argue that, in the twenty-first century, moving image archives will redefine their value to society not through preservation but through the decisions they make, which will affect not simply the intellectual community but the culture at large. The ways in which moving image archives situate new media materials and extend cooperation between institutions will determine, in large part, the discourse surrounding moving images throughout the upcoming century. / text

In the past thirty years, a growing community has emerged to advocate for the preservation and recognition of home movie collections based on their historical significance. Despite the significant cost of preserving and providing access to these collections and the myriad challenges they pose to archivists and researchers, no substantive research exists that evaluates their actual scholarly use or impact. Through a publication analysis and a survey of the Association of Moving Image Archivists, I sought to determine if there is a difference between whom archivists think should be using home movie collections and who is actually them. Though my findings suggest that home movies have yet to impact the scholarly work of historians, I offer recommendations for future research and professional development that may encourage increased scholarly use as well as increased collaboration between archivists and historians. / text

<p>GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.</p><p>The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter. Further to clarify which circumstances that have a negative effect on the organic reduction. During the three forthcoming years, an extensive reconstruction of the biological wastewater treatment facility will be accomplished. During the construction period the flow equalization will be very limited. Therefore an emission forecast with respect to organic matter was performed comprising the construction period during the years 2005, 2006 and 2007. This to estimate the safety margin to the emission standard during the construction period.</p><p>Several parameters were surveyed during the project, water temperature, pH, plural nutrition elements, flow, oxygen concentration, suspended solids, organic load and microbial activity. At two occasions, the parameters were extensively studied during a 24-hour period respectively. Two capacity experiments were performed in order to evaluate the organic reduction at different organic loads. The obtained results together with an estimation regarding the organic load performed by AB Ångpanneföreningen were used for the emission forecast. The forecast considered two cases, operation with and without dosage of a flow with high organic content from the local solvent recycling facility (called T10-dosage).</p><p>According to the forecast, the emission standard will be fulfilled during an average month regarding the organic load. This without T10-dosage and with an average reduction of 55 %. To fulfill the standard during a month with maximum organic load, a reduction of 65 and 75 % will be required in the cases without and with T10-dosage respectively. The organic reduction is negatively effected by lasting loads of 7 kg CODfilt/m3 or higher, or by a great increase of the load in a short period of time. Sporadic peaks regarding the organic load appeared to have temporary or no negative effects on the reduction. Flow variations during evenings, nights and weekends caused variations in the organic load with negative effect of the reduction rate. The oxygen concentration in the biological reactor has a conclusive significance of the reduction rate, a lower concentration than 2 mg/l affects the reduction rate in a negative way. The buffering capacity in the biofilm reactor showed to work excellently, the pH value varied between 6.8 and 8.9. There is an immediate risk of temperatures over 40^oC during the construction period. This could have a negative influence of the organic reduction. Individual measured temperatures of 38^oC did not have a negative effect on the reduction rate. The amount of suspended solids varied a lot in the outflow from the biological reactor and will continue to do so during the construction period.</p> / <p>GE Healthcare bedriver sin verksamhet i Uppsala vilken består av att utveckla system, utrustning och media för att rena läkemedelssubstanser. Vid diskussion med Uppsala kommuns VA- och avfallskontor väcktes frågan angående omprövning av tillståndet för verksamheten. Diskussionerna rörde planerade processförändringar och kompletteringar av bolagets biologiska processavloppsvattenrening. Av den anledningen ansågs det nödvändigt att utreda en för företaget ny processteknik för processavloppsvatten, vilket är bakgrunden till detta examensarbete. Den utvärderade processtekniken är en biofilmreaktor innehållande ett rörligt bärarmaterial med en stor skyddad yta för biologisk tillväxt. Biofilmreaktorn togs i drift under hösten år 2003 och därmed bestod det lokala reningsverket förenklat sett av en utjämningsanläggning följd av två parallella biosteg, ett biotorn med konventionell stationär biobädd över vilken processavloppsvatten spreds samt en biofilmreaktor med rörligt bärarmaterial.</p><p>Syftet med examensarbetet var att kartlägga biofilmreaktorns funktion med avseende på reduktion av organiskt material. Vidare att klargöra vid vilka förhållanden reduktionsgraden har påverkats negativt. Under de tre kommande åren skall en stor om- och tillbyggnad av reningsverket genomföras. Förändringen kommer att medföra att utjämningsvolymen blir mycket begränsad under ombyggnadsperioden. Av den anledningen var ytterligare ett syfte med examensarbetet att utföra en utsläppsprognos med avseende på organiskt material för åren 2005 till och med 2007. Detta för att bedöma säkerhetsmarginalen till utsläppsvillkoret under ombyggnadsperioden.</p><p>Examensarbetet realiserades genom att kartlägga parametrarna organisk belastning, organisk reduktion, vattentemperatur, pH, närsalter, flöde, koncentration löst syre, suspenderad substans samt mikrobiell aktivitet. Därutöver utfördes två kapacitetsförsök för att kartlägga den organiska belastningens inverkan på reduktionen. Vid det ena försöket skapades en högre organisk belastning genom att successivt öka flödesbelastningen över biofilmreaktorn. Vid det andra försöket doserades en delström (kallad T10-dosering) innehållande rester från den lokala lösningsmedelsåtervinningen med stort organiskt innehåll. Därtill utfördes två dygnsprovtagningar för att kartlägga ett flertal parametrars dygnsvariationer. Den framtagna utsläppsprognosen baserades på en belastningsprognos utförd av AB Ångpanneföreningen samt den i arbetet kartlagda reduktionen av organiskt material vid olika belastningar. Prognosen omfattar två fall, med eller utan T10-dosering.</p><p>Enligt utsläppsprognosen kommer utsläppsvillkoret inte att överskridas under åren 2005 till och med 2007. Detta gäller vid en för året genomsnittlig månad avseende belastning utan T10-dosering och med en genomsnittlig organisk reduktionsgrad på 55 %. Under en månad med maximal belastning krävs 65 % reduktion och 75 % med T10-dosering. Kapacitetsförsöken visade att reduktionsgraden påverkades negativt vid en varaktig belastning överstigande 7 kg COD_löst/m3 samt vid kraftiga belastningsökningar. Tillfälliga belastningstoppar hade endast kortvarig eller ingen negativ inverkan på reduktionen. Höga flöden under dagtid och låga flöden under nätter och helger orsakade variationer i den organiska belastningen, vilket hade en negativ inverkan på reduktionen. När koncentrationen löst syre i biofilmreaktorn understeg 2 mg/l påverkades mikroorganismerna negativt och därmed även reduktionen. Buffertkapaciteten i biofilmreaktorn var god under den studerade tidsperioden och pH-värdet varierade mellan 6,5 och 8,8. Under ombyggnadsperioden föreligger en stor risk för att vattentemperaturen kan bli för hög i biofilmreaktorn vid ett flertal tillfällen. Enstaka uppmätta temperaturtoppar på 38°C påverkade dock inte reduktionen negativt. I biofilmreaktorns utgående vatten varierade mängden suspenderad substans kraftigt, vilket även kommer att gälla under ombyggnadsperioden.</p>

For simulations of highly complex geometries, frequently encountered in many fields of science and engineering, the process of generating a high-quality, body-fitted grid is very complicated and time-intensive. Thus, one of the principal goals of contemporary CFD is the development of numerical algorithms, which are able to deliver computationally efficient, and highly accurate solutions for a wide range of applications involving multi-physics problems, e.g. Fluid Structure Interaction (FSI). Immersed interface/boundary methods provide considerable advantages over conventional approaches, especially for flow problems containing moving boundaries.In the present work, a novel, robust, highly-accurate, Immersed Interface Method (IIM) is developed, which is based on a local Taylor-series expansion at irregular grid points enforcing numerical stability through a local stability condition. Various immersed methods have been developed in the past; however, these methods only considered the order of the local truncation error. The numerical stability of these schemes was demonstrated (in a global sense) by considering a number of different test-problems. None of these schemes used a concrete local stability condition to derive the irregular stencil coefficients. This work will demonstrate that the local stability constraint is valid as long as the DFL-number does not reach a limiting value. The IIM integrated into a newly developed Incompressible Navier-Stokes (INS) solver is used herein to simulate fully coupled FSI problems. The extension of the novel IIM to a higher-order method, the compressible Navier-Stokes equations and the Maxwell's equations demonstrate the great potential of the novel IIM.In the second part of this dissertation, the newly developed INS solver is employed to study the flow of a stalled airfoil and steady/unsteady stenotic flows. In this context, a new biglobal stability analysis approach based on solving an Initial Value Problem (IVP), instead of the traditionally used EigenValue Problem (EVP), is presented. It is demonstrated that this approach based on an IVP is computationally less expensive compared to EVP approaches while still capturing the relevant physics.

This thesis considers the relationship between the ontology of time and the passage of time, and concludes that the best way to understand this relationship is found in the combination of eternalism with the view that the passage of time is an objective, irreducible fact about the spatio-temporal world. The steps I take to reach this conclusion are as follows: first, I propose that eternalism is the best ontological basis from which to consider temporal passage; second, I argue that the moving spotlight theory, which attempts to reconcile eternalism with temporal passage, is an inadequate representation of the relationship between eternalism and temporal passage; third, I suggest that temporal passage is best understood as a mind-independent phenomenon. I argue that eternalism is preferable to presentism insofar as presentism suffers from inconsistencies that eternalism both avoids and easily solves. I then defend the rejection of the moving spotlight theory by an appeal to the incoherency of the moving now. Finally, I dismiss mind-dependent temporal passage in favour of mind-independent temporal passage based on the irreducibility of temporal passage in and of itself. / Thesis (Master, Philosophy) -- Queen's University, 2013-09-12 21:21:29.147

The phrase “miner” is comparatively non-specific as mining is seen as a multi-disciplinary industry that includes several diverse professions and trades (Donoghue, 2004). One of the functions within mining is the operation of earth moving equipment (EME) such as haul trucks, dozers, excavators and graders. EME are generally used to shift large amounts of earth, dig foundations and landscape areas. In this study whole-body vibration (WBV) and noise exposure of earth moving equipment (EME) operators were assessed, at an opencast coalmine in South Africa. The aim was to evaluate and quantify the levels of exposure in different EME types, as well as to compare old with new EME, in order to estimate if machine hours contribute to higher noise and vibration levels. WBV and noise levels of the Production and Rehabilitation operations were compared, to determine whether different activities led to different exposures. Internationally accepted standardised methods, ISO 2631-1 for WBV and SANS 10083:2012 for noise were followed and correctly calibrated instrumentation was used. WBV measurements were conducted with a tri-axial seat pad accelerometer (SVAN 958) and personal noise dosimeters (Casella 35 X) were used for noise measurements. Measurements were taken over a period of four months. With regards to the European Union (EU) limit (1.15 m/s2) and the EU action limit (0.5 m/s2) it was noted that operators of EME within the Production operation were not exposed to WBV levels above the EU limit, but 77% of these operators were exposed to WBV levels above the EU action limit. It was also evident that 45% of operators’ vibration exposure levels were within the Health Guidance Caution Zone (HGCZ) of 0.45 – 0.90 m/s2. Within the Rehabilitation operation, 9% of operators were exposed to WBV levels above the EU limit and 55% above the EU action limit. Furthermore 50% was within the HGCZ. With regards to the noise Occupational exposure limit (OEL) of 85 dB(A) as stated by the Mine Health and Safety Regulations (MHSR) it was noted that 27% of operators within the Production operation were exposed to noise levels above the limit and for operators within the Rehabilitation operation 14% were reported to be exposed at or above the limit. Statistically significant difference in noise exposure was found between the Production operation and Rehabilitation operation. Results indicated that the majority of EME operators were exposed to high noise levels, in some cases exceeding the 85 dB(A) OEL. A significant positive correlation was found between noise exposure levels and machine hours. Thus higher noise levels were observed as machine operating hours increased. It was found that operators were exposed predominantly to vibration and noise levels below the limits. However the Dozer group within the Production and Rehabilitation operations in some cases exceeded the vibration and noise legal limit. High exposure levels within the Dozer group can be attributed to the fact that these EME types mostly perform activities in uneven areas and the tracks on which these Dozers move also contribute to higher vibration levels due to a lack of a suspension. Controls should be implemented as far as is reasonably practicable to ensure that operators are not exposed above recommended or permissible levels for each hazard. Continuous improvement of the maintenance plan for all EME and regularly grading and maintaining travelling ways are some of the controls that will contribute to lower vibration and noise levels. Operators exposed to high noise levels should use hearing protective devices as an early on preventative measure to reduce noise exposure levels. / MSc (Occupational Hygiene), North-West University, Potchefstroom Campus, 2014

The fundamental conceptualisation of what animation actually is has been changing in the face of material change to production and distribution methods since the introduction of digital technology. This re-conceptualisation has been contributed to by increasing artistic and academic interest in the field, such as the emergence of Animation Studies, a relatively new branch of academic enquiry that is establishing itself as a discipline. This research (documentation of live events and thesis) examines animation in the context of performance, rather than in terms of technology or material process. Its scope is neither to cover all possible types of animation nor to put forward a new ‘catch-all’ definition of animation, but rather to examine the site of performance in character animation and to propose animation as a form of performance. In elaborating this argument, each chapter is structured around the framing device of animation as a message that is encoded and produced, delivered and played back, then received and decoded. The PhD includes a portfolio of projects undertaken as part of the research process on which the text critically reflects. Due to their site-specific approach, these live events are documented through video and still images. The work represents an intertwining, interdisciplinary, post-animation praxis where theory and practice inform one another and test relationships between animation and performance to problematise a binary opposition between that which is live as opposed to that which is animated. It is contextualised by a review of historical practice and interviews with key contemporary practitioners whose work combines animation with an intermedial mixture of interaction design, fine art, dance and theatre.

Going against phalloculocentrism’s situation in a hom(m)o-sexual paradigm and structuration of the male gaze and moving towards a gyneacentric perspective, the thesis explores how a feminised process of reception and interaction with artworks might arise. My installation and moving-image practice-led research is driven by a central question: How might a feminised form of spatiality, based on a gyneacentric model, deform an audience’s phalloculocentric reading of an artwork? The purpose of this thesis is to find a practice-led feminist method of producing an artwork that actively represents the feminine and de-centres an audience’s (male) gaze. By dislocating the eye from the lens of a camera, I propose to alter an audience’s usual cinematic experience of an image of the feminine through my artwork. This is developed through my proposition for composing an experience of her image through inter-relational exchanges in order to shift the register of reception from gazing to “touching”. I claim this could provide a potential for an embodied feminised process of spatiality and perception. A method of cartographically mapping the feminine through diagrams, photographs, drawings and video is developed in the preparation and installation of the central artwork that structures the thesis, (f)low visibility, in a nightclub. Feminist (installation and video) practitioners’, Martha Rosler, Louise Bourgeois, Mona Hatoum and Pipilotti Rist, approaches to representing the feminine are also investigated. The preparatory designs attempt to subvert the potential for a voyeuristic reception and/or exhibitionistic composition of the installation. This forms an investigation into how the reception and interaction with a feminised image might arise through a tactile process of exploration. I propose that although (f)low visibility produced ungraspable feminised on-screen images it afforded embodied partially locatable inter-relational exchanges in its reception of her. Luce Irigaray’s and Donna Haraway’s theories of embodiment are developed and intertwined in my conclusion. I claim that interaction with and reception of monstrous cyborg images on-screen occurred through the navigation of a fantasy of intrauterine “touching” in (f)low visibility’s installation as a feminised process of spatiality.

The basis for performing a thermo-mechanical staggered coupled heat source analysis of a welding simulation is implemented into LS-DYNA. In this report, three methods for initiating the heat source’s mechanical motion during girth and tubular joint welding are developed and evaluated. The first method is a reformulation of the equations used at Det Norske Veritas, the second is an incorporation of the equations into excel and the third is a standalone third party software. The most efficient of the developed methods turned out to be the software which creates k-files which are implemented into the main k-file using LS-PrePost. All methods have been visually and numerically evaluated using Excel, LS-DYNA and LS-PrePost.
