    Influence of the Coriolis force in atom interferometry

    Full text link
    In a light-pulse atom interferometer, we use a tip-tilt mirror to remove the influence of the Coriolis force from Earth's rotation and to characterize configuration space wave packets. For interferometers with large momentum transfer and large pulse separation time, we improve the contrast by up to 350% and suppress systematic effects. We also reach what is to our knowledge the largest spacetime area enclosed in any atom interferometer to date. We discuss implications for future high performance instruments.Comment: 4 pages, 5 figures, 1 tabl

    SPONSORSHIP IN ACTIONS SPORTS: A CRITICAL ANALYSIS

    The world of action sports sponsorship is one that is constantly changing and is continuing to grow by the day. The goal of this project is to contribute to the understanding and assessment of sponsorship efforts in action sports. Companies such as Red Bull and Monster Energy are pioneers in this space and have seen high levels of success as a result of their efforts to sponsor athletes and team. The question remains, as this area of business continues to grow, so does the cost of sponsorship, how can a simple sticker on a helmet or vinyl on the side of a car justify the millions of dollars spent on the sponsorship? The simple answer is that there are many hidden factors at play. Sponsorship efforts create significant results in terms of intangible factors, these are assets such as brand, awareness, brand image, social media presence and so on. Following the path model these translate into tangible results such as purchases, sales revenue, profit, and other concrete examples of increased financial success for the company. However, these efforts tend to have a lagging effect. This means that if a company sponsors and event, the results may not be seen for weeks or months. These efforts may cause direct purchases of products immediately but more often, the brand or logo is stored in the consumers brain and creates brand awareness and recognition. This puts the company at the top of their mind when it comes time to purchase. Overall, the path model illustrates how these sponsorships pay off for companies sponsoring events. However, how the processes in between initial sponsorship and desired increase profit numbers remains in muddy waters. Companies need to look more critically on how much of the marketing budget is allocated to sponsorship, especially those who are not seeing results but believe they are on the horizon.Master of Art

    University, Church, and Social Change: The Case of Catholic Colleges in Ontario, 1931-1961

    This paper is based upon research covering the period 1931-61 and is aimed at examining relationships between Roman Catholic social teaching and conse quent social action within the Province of Ontario. The seven studies constituting the research focused on six distinct areas in and around the cities of Windsor, London, Hamilton, Toronto, Ottawa, and Sudbury. Excluding seminaries or theologates, four of these cities contained one Catholic post-secondary institu tion, typically identified as an ' Arts and Science' college or university, and the city of Ottawa contained two such institutions

    Mid-infrared optical sensing using sub-wavelength gratings

    Get PDF
    Optical sensing has shown great potential for both quantitative and qualitative analysis of compounds. In particular sensors which are capable of detecting changes in refractive index at a surface as well as in bulk material have received much attention. Much of the recent research has focused on developing technologies that enable such sensors to be deployed in an integrated photonic device. In this work we demonstrate experimentally, using a sub-wavelength grating the detection of ethanol in aqueous solution by interrogating its large absorption band at 9.54 μm. Theoretical investigation of the operating principle of our grating sensor shows that in general, as the total field interacting with the analyte is increased, the corresponding absorption is also increased. We also theoretically demonstrate how sub-wavelength gratings can detect changes in the real part of the refractive index, similar to conventional refractive index (RI) sensors
