Stratigraphy and Environmental Analysis of the Swan Peak Formation and Eureka Quartzite, Northern Utah

Francis, George Gregory 01 May 1972 (has links)
The Swan Peak Formation in north-central Utah thickens westward, from zero feet near Logan to 687 feet in the Promontory Range. The unit is subdivided into three distinct members: 1) A lower member of interbedded shales, limestones, and quartzites; 2) A middle member of interbedded shales and brown quartzites; and 3) An upper member of white quartzites. The Swan Peak thins southward toward the east-west-trending Tooele Arch in the area of study; this thinning probably reflects both lesser deposition and greater subsequent erosion there than elsewhere. The lower member in northern Utah probably was deposited in shallow-shelf and/or transitional shorefaceshelf environments. The middle member represents shoreface to intertidal environments. Western miogeosynclinal equivalents of the lower and middle members are more carbonate-rich, the results of their more basinward position and thus greater distance from terrigenous sediment sources. The upper member was deposited in a shallow-shelf to intertidal environment by strong, predominantly south-flowing currents.

Edgar Allan Poe and Science: Unraveling the Plot of the Universe

Ellison, Murray S. 01 January 2015 (has links)
Edgar Allan Poe (1809-49) lived at the perfect time to write about several of the most dramatic technological developments ever recorded in history. Up until the nineteenth century, professional scientists were almost the exclusive agents for writing about science. However, during this period, non-professional writers also emerged as important conveyors of popular science news to the public. Though Poe was a lay writer, his popular writing conveyed several of the most important new discoveries of the Industrial Age. He also projected his views about how nineteenth-century technologies might impact civilizations of the future. Poe’s writing offers a key example of a widespread movement of thinkers who attempted to mediate the tensions and debates that were taking place in his lifetime between those who perceived and described the world from either the “Mechanical” or the “Romantic” approach. This study explores the ways that Poe wrote about science in poetry, non-fiction, and fiction. I argue that a review of his earlier science writing helps to unlock several of the enigmatic writings of his culminationg work, Eureka:A Prose Poem. The final chapter of this thesis concludes with an in-depth discussion of Eureka. In Eureka, Poe proposes that man’s literary works are imperfect. However, he contends that the Creator has written and executed a perfect “Plot of the Universe.” Poe attempts to unravel several of its deepest mysteries in a multi-genre work of poetry, history, science, and metaphysics. I argue that modern scholars of literature and science history can gain a clearer view of the ways that the nineteenth-century public received and understood information about science by exploring Poe’s science writing than has been provided in previous historical or literary scholarship.

Rozmiestnenie a konkurencieschopnosť hi-tech priemyslu v EÚ / Location and competitiveness of hi-tech industry in EU

Krošlák, Peter January 2011 (has links)
The aim of my master's thesis is to assess the influence of research support of European Union on location and competitiveness of European high-tech industry. After defining high-tech industry according to OECD and ČSÚ (Czech statistical office) follows a part dealing with different forms of support of EU for high-tech industry, while the focus is also on volume and efficiency of invested money. I try to analyze the location with regard to European support and Porter's diamond theory. Since high-tech industry is usually concentrated in clusters, which are rather abundant in Europe as well, the focus is only on a few selected regions. Last part compares European competitiveness with that of other OECD members and developing countries based on data from OECD and Eurostat.

Poe's Entangled Fiction: Quantum Field Theory in "The Colloquy of Monos and Una" and "The Mystery of Marie Rogêt"

Little, Jean A. 01 June 2016 (has links)
When seen among the constellation of Edgar Allan Poe's works culminating in Eureka, "The Colloquy of Monos and Una" and "The Mystery of Marie Rogêt," take on an important role as vehicles for scientific contemplation. Similar to early quantum physicists, such as Einstein and Schrödinger, Poe uses macro-level analogies to explore the unity of individual entities, which becomes an important tenet of his explanation of the universe. His thought experiments also resemble those of modern physics in their approach to reality as probabilistic, an idea that finds its echo in quantum field theory, which distinguishes between observed particles and their underlying existence as vibrations in a field rather than distinct units. In this thesis, I use specific examples from "Monos and Una" to demonstrate that the barrier between individuals blurs when viewed from the perspective of a unified field. I also examine ways that "Marie Rogêt" expands the idea of a unified field in terms of entangled individuals and correlated events, and pushes against the Newtonian deterministic tradition. In the context of Poe's body of work, these stories depart from the aesthetic that characterizes many of his most widely-read stories, in that their exploration of the scientific seems to overtake the narrative. However, their composition, which leaves some readers dissatisfied, expertly comments on the dichotomy between the observed and the real, and the role that narrative plays in interpreting experience.

Creativity in consulting engineering: how civil engineers talk about design

Hayes, Marion January 2005 (has links)
An appropriate civil infrastructure is vital to the wealth and wellbeing of cultures. Appropriateness is increasingly defined in terms of sustainability, aesthetics, innovation and cultural suitability. These expectations pose challenges for engineers to use their creativity, aesthetic appreciation, knowledge and character to predict and respond creatively with their designs. However, a treadmill of cost innovation in construction projects makes improved design challenging. This tends to reinforce the misconception that engineers are dull and uncreative, even though historically they have displayed considerable imagination and ingenuity. This thesis is based on an in-depth study conducted at the Brisbane office of Kellogg Brown & Root P/L (a large consulting engineering firm). A contemporary qualitative approach is used to explore how creativity is manifested in an engineering design context, and how it relates to phenomena such as knowledge, innovation, project culture and organizational environment. In-depth interviews reveal the authentic meaning of design and creativity for engineers and other company staff. The study highlights an important distinction between design-based and cost-driven innovation and unveils multiple influences that can stifle or nurture personal and group creativity.

Caractérisation in situ des propriétés optiques et microphysiques des aérosols troposphériques dans l’archipel arctique canadien

Vicente-Luis, Andy 12 1900 (has links)
Le réchauffement climatique dans l’Arctique canadien est deux fois plus rapide que la moyenne globale, ce qui accélère la fonte de la banquise et bouleverse radicalement la faune, la flore et les communautés de la région tout entière. Ce réchauffement est causé non seulement par la hausse des émissions de gaz à effet de serre, mais également par des agents de forçage climatique de courte durée comme les aérosols troposphériques. Toutefois, le forçage radiatif des aérosols dans la région polaire est beaucoup moins bien estimé que celui des gaz à effet de serre, notamment le CO2, et demeure toujours incertain. Cette grande incertitude résulte principalement de la grande variabilité spatiotemporelle des propriétés chimiques et physiques des aérosols, en plus de la complexité des boucles de rétroaction observées en Arctique. D’ailleurs, les données sur les caractéristiques des aérosols et de leur répartition à travers la région sont très limitées, et ce, plus particulièrement dans le Haut-Arctique canadien. Pour remédier à ce problème, une série de mesures a été effectuée sur une période de 3 ans (2016-2019) dans le laboratoire de recherche sur l’environnement atmosphérique polaire (PEARL, 80N 86O) situé près de la station météorologique d’Eureka, au Nunavut, Canada. La distribution en taille des aérosols a été mesurée en se servant de plusieurs instruments, dont un compteur optique de particules (OPC), un granulomètre de mobilité électrique à balayage (SMPS) et un granulomètre aérodynamique (APS). Les propriétés optiques des aérosols ont été déterminées avec deux extinctiomètres photoacoustiques (PAX) qui opèrent respectivement à des longueurs d’onde de 405 et 870 nm. Les observations réalisées à l’observatoire PEARL démontrent une forte variation saisonnière dans les propriétés optiques et microphysiques des aérosols polaires. Pendant l’hiver et le printemps, l’atmosphère arctique est envahie par une brume sèche d’origine anthropique qui se traduit par une forte augmentation dans la taille, la concentration en nombre et les propriétés optiques extensives des aérosols. Les épisodes de brume arctique commencent généralement en mi-décembre, où des évènements de poussières minérales ont aussi été observés, et se terminent en mai où la formation et le grossissement de nouvelles particules s’amorcent. Le début du printemps mesure les concentrations d’aérosol en mode accumulation les plus élevées durant l’année. Les aérosols les plus sombres qui composent la brume arctique ont été identifiés comme étant de la suie ou du carbone noir transporté dans l’Arctique à partir de l’Eurasie et de l’Alaska. Quelques relations systématiques entre les propriétés optiques et la distribution de taille des aérosols ont également été calculées et révèlent une différence majeure entre les aérosols interagissant avec la lumière à 405 et 870 nm. / Global warming in the Canadian Arctic is twice as fast as the global average, accelerating the melting of sea ice and radically disrupting the fauna, the flora, and the communities of the whole region. Arctic warming is caused not only by rising greenhouse gas emissions, but also by the short-lived climate forcing agents such as tropospheric aerosols. However, aerosol radiative forcing in the polar region is less precisely estimated than that of greenhouse gases, notably CO2, and remains highly uncertain. This large uncertainty arises mainly from the high spatiotemporal variability in aerosol chemical and physical properties, in addition to the complexity of the feedback loops observed in the Arctic. Furthermore, datasets on aerosol characteristics and their distribution across the region are very limited, particularly in the Canadian High Arctic. To address this issue, a series of measurements were conducted over a 3-year period (2016-2019) at the Polar Atmospheric Environment Research Laboratory (PEARL, 80N 86W) near Eureka weather station, in Nunavut, Canada. Aerosol size distribution was measured using several instruments including an Optical Particle Counter (OPC), a Scanning Mobility Particle Sizer (SMPS), an Aerodynamic Particle Sizer (APS). Aerosol optical properties were determined by two Photoacoustic Extinctiometers (PAXs) which operate at wavelengths of 405 nm and 870 nm, respectively. Observations made at the PEARL observatory show a strong seasonal variation in the optical and microphysical properties of polar aerosols. In the winter and spring, the Arctic atmosphere is impacted by an anthropogenic haze that results in a sharp increase in aerosol size, number concentration, and optical properties. Arctic haze episodes typically occur in mid-December, when mineral dust events have also been observed, and end in May when formation and growth of new particles begin. Early spring exhibits the highest accumulation-mode aerosol concentrations during the year. The darkest Arctic haze aerosols have been identified as soot or black carbon transported into the Arctic from Eurasia and Alaska. Some systematic relationships among aerosol optical properties and size distribution have also been calculated and reveal a major difference between aerosols interacting with light at 405 nm and 870 nm.

THE IMPACT OF DYNAMIC GAME DIFFICULTY BALANCING ON PLAYER USER EXPERIENCE IN PUZZLE GAMES : A case study

Lin, Qian January 2023 (has links)
This study delves into the relationship between Dynamic Game Difficulty Balance and Game User Experience in the context of puzzle games. The aim of this study was to explore the impact of DGDB on user experience in puzzle games, focusing on player engagement, immersion, and the occurrence of a-ha moment. To this end, the researchers conducted a control group experiment and analyzed the results both quantitatively and qualitatively based on participants' objective data during the game and subjective responses in the post-game questionnaire. The findings suggest that DGDB has the potential to increase player engagement and satisfaction, but the impact is modest, as evidenced by higher completion rates and flow channels in puzzle games. We explored the impact of the DGDB system on a-ha moment and the results were mixed. However, it is clear that the relationship between DGDB and puzzles is a delicate one, with players' preferences and perceptions varying.
