Academic literature on the topic 'Publish files'

Visma Labs AB or Visma wanted to conduct experiments to see if file metadata could be indexed for searching files on a public cloud storage. Given that storing files in a public cloud storage is cheaper than the current storage solution, the implementation could save Visma money otherwise spent on expensive storage costs. The thesis is therefore to find and evaluate an approach chosen for indexing file metadata and searching files on a public cloud storage with the chosen distributed search engine Elasticsearch. The architecture of the proposed solution is similar to a file service and was implemented using several containerized services for it to function. The results show that the file service solution is indeed feasible but would need further tuning and more resources to function according to the demands of Visma.<br>Visma Labs AB eller Visma ville genomföra experiment för att se om filmetadata skulle kunna indexeras för att söka efter filer på ett publikt moln. Med tanke på att lagring av filer på ett publikt moln är billigare än den nuvarande lagringslösningen, kan implementeringen spara Visma pengar som spenderas på dyra lagringskostnader. Denna studie är därför till för att hitta och utvärdera ett tillvägagångssätt valt för att indexera filmetadata och söka filer på ett offentligt molnlagring med den utvalda distribuerade sökmotorn Elasticsearch. Arkitekturen för den föreslagna lösningen har likenelser av en filtjänst och implementerades med flera containeriserade tjänster för att den ska fungera. Resultaten visar att filservicelösningen verkligen är möjlig men skulle behöva ytterligare modifikationer och fler resurser att fungera enligt Vismas krav.

Bubbles in water are stabilised against coalescence by the addition of salt. The white froth in seawater but not in freshwater is an example of salt-stabilised bubbles. A range of experiments have been carried out to investigate this simple phenomenon, which is not yet understood.¶ The process of thin film drainage between two colliding bubbles relates to surface science fields including hydrodynamic flow, surface forces, and interfacial rheology. Bubble coalescence inhibition also stands alongside the better known Hofmeister series as an intriguing example of ion specificity: While some electrolytes inhibit coalescence at around 0.1M, others show no effect. The coalescence inhibition of any single electrolyte depends on the combination of cation and anion present, rather than on any single ion.¶ The surfactant-free inhibition of bubble coalescence has been studied in several systems for the first time, including aqueous mixed electrolyte solutions; solutions of biologically relevant non-electrolytes urea and sugars; and electrolyte solutions in nonaqueous solvents methanol, formamide, propylene carbonate and dimethylsulfoxide. Complementary experimental approaches include studies of terminal rise velocities of single bubbles showing that the gas-solution interface is mobile; and measurement of thin film drainage in inhibiting and non-inhibiting electrolyte solution, using the microinterferometric thin film balance technique.¶ The consolidation of these experimental approaches shows that inhibiting electrolytes act on the non-equilibrium dynamic processes of thin film drainage and rupture between bubble surfaces – and not via a change in surface forces, or by ion effects on solvent structure. In addition, inhibition is driven by osmotic effects related to solute concentration gradients, and ion charge is not important.¶ A new model is presented for electrolyte inhibition of bubble coalescence via changes to surface rheology. It is suggested that thin film stabilisation over a lifetime of seconds, is caused by damping of transient deformations of film surfaces on a sub-millisecond timescale. This reduction in surface deformability retards film drainage and delays film rupture. It is proposed that inhibiting electrolyte solutions show a dilational surface viscosity, which in turn is driven by interfacial concentration gradients. Inhibiting electrolytes have two ions that accumulate at the surface or two ions that are surface excluded, while non-inhibiting electrolytes have more evenly distributed interfacial solute. Bubble coalescence is for the first time linked through this ion surface partitioning, to the ion specificity observed at biological interfaces and the wider realm of Hofmeister effects.¶

À partir d'une analyse des prises de masse obtenues lors de croissance de nanotubes de carbone par CCVD suivie par micro-blance à quartz, un modèle cinétique est élaboré à l'échelle de la particule pour comprendre les mécanismes de la nucléation et de la croissance. Nous avons développé une étude des différentes étapes du procédé CCVD incluant une décomposition associative de l'hydrocarbure sur la face catalytique du catalyseur, la diffusion de surface et de volume du carbone, la nucléation et la croissance du nanotube résolue par une méthode de différences finies. Nos résultats indiquent très clairement que les processus de surface sont cinétiquement déterminants. La non-prise en compte des phénomènes à l'échelle atomique ne nous permet pas de prédire quelles sont les structures carbonées qui se forment pendant l'étape de nucléation ou de déterminer avec précision le chemin parcouru par un atome de carbone depuis la face catalytique jusqu'à son insertion dans le nanotube de carbone. Nous avons donc entrepris d'étudier la migration d'un atome de carbone depuis la surface du catalyseur jusqu'au plan graphitique constituant le nanotube de carbone à l’aide d’un code de calcul basé sur la méthode MEAM. La nouvelle génération de matériaux pour le stockage d'information nécessite la conception de réseaux réguliers ultra-denses de nanoparticules ferromagnétiques pouvant être synthétisés par méthode PE-CVD. Des simulations Monte-Carlo ont été effectuées pour sonder l'effet sur les propriétés magnétiques d'une augmentation de l'anisotropie des particules et/ou de la densité sur les capacités de stockage. Nos résultats montrent qu'un rapport d'aspect supérieur à 4 ne change pas fondamentalement les propriétés magnétiques du système et qu'avec de tels systèmes des capacités de stockage de l’ordre de 10 Tbits/inch² sont evisageables<br>A kinetic model for the growth of carbon nanotubes is develloped based on experimental data obtained by TEOM-CCVD synthesis of CNTs. The model takes into account associative decomposition of hydrocarbon on the surface of the catlytic particle, surface and volume diffusion, nucleation and growth of CNTs solved by finite differnce method. The surfacic process seems to be the rate determining step. To take into account microscopic scale effects a MEAM based programm is developped to analyse the path followed by an atom of carbon from the the catalytic facet to the graphitic shell of the CNT to determine whether the diffusion is volumic, sub-surfacic or surfacic. An experimental method to obtain ultra-high density assemblies of ferromagnetic nanoparticles is the Plasma-Enhanced CCVD. Monte-Carlo numerical simulations are developped to analyse the magnetic properties of such devices. We show that an aspect ratio superior to 4 does not change the magnetic propreties of the system and that we could reach with such devices a density of 10 Tbits/inch², 20 times more than what is done at the moment

The tourism industry is vulnerable to crises and disasters and increasingly government and industry stakeholders are turning their attention to how to prevent, manage and recover from shock events. In the last decade there has been increasing interest in tourism research on crises and disasters, prompted in part by recognition of the tourism industry's vulnerabilities and what appear to be more frequent shock events. The beginning of this century has been marked by a series of crises and disasters including the 2001 Foot and Mouth Disease outbreak in the United Kingdom, the 2001 terrorist hijackings in the USA, the 2002 and 2005 Bali bombings, the 2003 SARS epidemic in southeast Asia and Canada, the 2004 Indian Ocean tsunami and Hurricane Katrina in the southern USA in 2005 (Henderson, 2007). The Intergovernmental Panel on Climate Change (2007a) has also predicted that the extreme weather events associated with climate change will lead to more natural disasters. Crises and disaster have local, regional and global repercussions on the tourism industry at business/corporate, industry and destination levels and the need for more attention to preparation, response and recovery is acknowledged. Much of the initial tourism research in this field focused on descriptions of crises and disasters and their impacts on tourism with some reflection on their management. This foundation and the comprehensive crisis and disaster literature from disciplines such as psychology, sociology, economics, geography and environmental science led to development of crisis and disaster management frameworks specifically designed for the tourism industry. These frameworks have achieved varying degrees of acceptance amongst tourism researchers with Faulkner and Vikulov's (2001) Tourism Disaster Management Framework (TDMF) being the most well known and often cited. The more recent Crisis and Disaster Management Framework (CDMF) developed by Ritchie (2004) is a useful destination-level framework based on a strategic management approach. Despite the development of these frameworks, relatively little tourism research effort has focused on destination recovery and very little on medium and long term recovery. In addition, there is little research on wildfires as a type of natural disaster. The extensive bushfires in the Australian Capital Territory (ACT) in 2003 (often referred to as the Canberra fires) provided an opportunity to investigate in a longitudinal study the short, medium and long term actions undertaken by the government and tourism industry to assist destination recovery and then compare them with Ritchie's prescriptive CDMF. Being longer term research this study is able to consider almost the entire recovery stage whereas other research has focused on short or medium term recovery (for example Faulkner & Vikulov, 2001). This research centred on a case study which is defined by Yin (1989 quoted in Wimmer & Dominick, 1997, p. 102) as an 'empirical inquiry that uses multiple sources of evidence to investigate a contemporary phenomenon within its real-life context'. This case study used interviewing, the documentary method and participant observation as the key methods. Representatives of government and the tourism industry were interviewed in-depth about the actions taken by their organisations or businesses. The interviews were semi-structured with mostly open-ended questions and some participants undertook multiple interviews over a three year period. Extensive secondary data and documentation about the bushfire and subsequent response and recovery was generated by the ACT government, industry and community and publicly available sources included reports and reviews, media releases, newspaper articles, newsletters, brochures, websites and legal and coronial enquiries. These were critical for gaining a comprehensive understanding of recovery. Participant observation was also important and, as a resident of the ACT, the author participated in relevant events and observed the public face of community recovery. The three methods resulted in a large data set that was distilled into a 'response and recovery story' structured according to Ritchie's CDMF. Upon comparing the findings with the framework, it was found that many elements were evident in the 'real life' case study including crisis communication, resource management, stakeholder communication, destination restoration and disasters as agents for change. There were also new findings that could be integrated into a redeveloped framework including the establishment of a recovery team, training for crisis and disaster management, tourist/visitor management, recovery planning, human resource management issues, business recovery tools, partnerships and memorialisation and commemoration. The resulting Tourism Industry Crisis and Disaster Management Framework (TICDMF) is a practical and comprehensive tool for Destination Management Organisations (DMOs) that both describes what occurred in a real life case study but also prescribes recommended management actions. In addition to specific recommendations for the ACT tourism industry, this research also resulted in general recommendations to the tourism industry, government and educators. These focused on (i) the importance of crisis and disaster management planning, (ii) the need to evaluate and document response and recovery and devote adequate resources to organisational learning, (iii) potential use of tools like the TICDMF and the plethora of resources to manage crises and disasters, (iv) educating staff, academics and tertiary tourism and hospitality students about crisis and disaster management and (v) accepting the chaos of recovery and devoting adequate resources to address the resulting complexity. The tourism industry is vulnerable to external shocks whether they be local crises or national disasters. The preparedness of the industry and its ability to effectively respond and recover is of critical importance for destinations and the community in which they function. Case studies of crises and disaster and development of a body of theoretical and practical knowledge will ensure that government and industry continue to play an important role in caring for the safety and security of tourists while maintaining a viable and sustainable industry for all stakeholders.

The work of documentary director Errol Morris can be approached in a variety of ways as it intersects and engages with many of the major themes of film and television scholarship - genre, authorship, and historical representation. But while his films and television episodes expose debates within film and documentary studies, they also call up major elements of postmodern debates within the historical discipline. Morris makes historical documentaries that do not simply render a (hi)story visually; he also attempts to draw viewers' attention to the conventions and construction of both visual media and of history. His work reveals both his keen awareness of postmodern historical debates, and a willingness to play, to confront basic assumptions, question boundaries, and to contribute to those debates. In 'Errol Morris and the Art of History', I argue that Morris is a visual historian; his films and television episodes draw as much from his understanding of historiographical debates as they do from his knowledge and artistic approach to visual media. All of Morris' work challenges the notion of objectivity in both documentary filmmaking and history; he attempts to illuminate the limits and conventions of visual depictions of history; he uses strategies to denaturalise historical and narrative construction, the naturalising tendencies of visual media, and the conventions of documentary practice; and he attempts to promote increased critical reflection. This thesis closely examines Morris' documentary films and television episodes to consider the structure and strategies that characterise his work, and situate it within contemporary film and historical debates. I explore Morris' methods and approach to documentary and history, showing how his work relates to postmodern history debates, to written and visual representations of history, and to documentary history and theory, including more recent factual forms like reality television.

The Public Libraries Survey is conducted annually by the National Center for Education Statistics through the Federal-State Cooperative System for Public Library Data. The data are collected by a network of state data coordinators appointed by the chief officers of state library agencies in the 50 States, the District of Columbia, and the outlying areas. Data are collected on population of legal service area, service outlets, public service hours, library materials, total circulation, circulation of children's materials, reference transactions, library visits, children's program attendance, electronic services and information, staff, operating income, operating expenditures, capital outlay, and more.

La souche Pseudoalteromonas sp. NC201, isolée en Nouvelle-Calédonie, possède des propriétés antibactériennes et probiotiques dans le cadre d’élevages larvaires de crevettes. Ainsi, cette souche bactérienne constitue une alternative à l’utilisation des antibiotiques. Ce travail de thèse a été focalisé sur la caractérisation de NC201 et de son potentiel antimicrobien ainsi que sur l’étude de son effet sur la crevette, Litopenaeus stylirostris lors de challenges expérimentaux. L’analyse du génome de NC201 a révélé la présence de clusters de gènes codants des composés antimicrobiens ainsi que deux amino acides oxydases. Une de ces oxydases a été identifiée comme capable d’inhiber des Vibrio pathogènes de L. stylirostris. Les essais in vivo ont permis de confirmer le rôle probiotique de NC201. En effet NC201 a été responsable d’une amélioration de la survie des animaux lors de stress hypo et hypersalins mais aussi lors de challenge biotique par infection avec V. nigripulchritudo. Le suivi dans l’hémolymphe de NC201 et V. nigripulchritudo a mis en évidence que ces deux bactéries étaient capables individuellement de coloniser l’hémolymphe des animaux, cependant, une exclusion mutuelle des deux bactéries a été observée dans ce compartiment. L’expression de gènes liés à la réponse immunitaire ainsi qu’à la réponse au stress oxydant a été quantifiée suite au traitement probiotique et au challenge avec V. nigripulchritudo. La quantification et l’activité enzymatique de biomarqueurs du stress oxydant ont été mesurées. Les modulations de ces biomarqueurs ont révélé que la souche NC201 conférait aux crevettes un état de santé général plus performant pour répondre à des stress<br>The Pseudoalteromonas sp. NC201 strain, isolated in New Caledonia, displayed antibacterial and probiotic properties in shrimp hatcheries. This strain is an alternative to antibiotics use. This thesis focused on the characterization of NC201, its antimicrobial potential as well as on the study on its effect on Litopenaeus stylirostris during experimental challenges. The analysis of the complete genome sequence of NC201 revealed multiple clusters coding for potential antimicrobial compounds as well as two amino acid oxidases. One of these oxidases was identified as capable of inhibiting Vibrio pathogenic to L. stylirostris such as V. penaeicida and V. nigripulchritudo. In vivo trials confirmed the probiotic role of NC201 towards L. stylirostris. Indeed NC201 was responsible for higher survival rates in animals confronted to hypo and hypersaline stress as well as to bacterial challenge through infection with V. nigripulchritudo. During experimental infections the presence of NC201 and V. nigripulchritudo was monitored in the shrimp hemolymph. Both bacteria are capable of invading the shrimp’s hemolymph but seemed mutually exclusive in this compartment during the 24 hours following the infection. The expression profile of genes involved in the immune response and the response to oxidative stress were quantified in the hemolymph and hepatopancreas, respectively. Enzymatic activities and quantification of bioindicators of oxydative stress were measured in the hepatopancreas. These modulations highlighted that NC201 induced an increase in the shrimp overall health status leading to enhanced responses to stresses
