    Get PDF
    The purpose of this report is to present a brief but comprehensive overview of the variety of innovations related to aviation, and to discuss their impact on scientific progress over the course of human history. Relevant discoveries from the fields of physics and aerodynamics, and the numerous technologies built based upon these discoveries, are discussed over a period ranging from ancient times to the twenty-first century. The scope of this report is an overview of the development of powered and unpowered aircraft, including lighter-than-air, heavier-than-air, and aerospace technologies. Aviation developments were generally not limited to one specific country or person, but often came from a combination of research and testing from many engineers and enthusiasts from a variety of locations and backgrounds. Races to meet milestones would inspire competition between individuals, scientific institutions, and countries. It is hoped that this report will be instructive to readers who may not have extensive familiarity with aviation-related history, and will promote personal research and interest

    Howzat? The Financial Health of English Cricket: Not Out, Yet

    In 1997 a review of the financial health of English county cricket highlighted strategic weaknesses within the professional game, principally an over-reliance by clubs on the annual grants provided to them by the England and Wales Cricket Board (ECB). Without such grants the teams, in general terms, would be insolvent. Using the financial statements of the First Class Cricket Counties, this paper explores how the financial position and performance of the county game has changed, 20 years on from the seminal study. A series of structural changes to the game had been made, yet financial problems are still evident. Counties are as reliant on central grant income as they were in 1997, although there are cases where clubs have made strategic enhancements and are becoming self-sustainable as going concerns. Rather than the ECB directly funding county revenue it should be working in collaboration with individual clubs to achieve developments in the game from the grassroots upwards, in order to help clubs grow their own revenue streams.</jats:p

    The sensitivity of rapidly rotating Rayleigh--B\'enard convection to Ekman pumping

    The dependence of the heat transfer, as measured by the nondimensional Nusselt number NuNu, on Ekman pumping for rapidly rotating Rayleigh-B\'enard convection in an infinite plane layer is examined for fluids with Prandtl number Pr=1Pr = 1. A joint effort utilizing simulations from the Composite Non-hydrostatic Quasi-Geostrophic model (CNH-QGM) and direct numerical simulations (DNS) of the incompressible fluid equations has mapped a wide range of the Rayleigh number RaRa - Ekman number EE parameter space within the geostrophic regime of rotating convection. Corroboration of the NuNu-RaRa relation at E=107E = 10^{-7} from both methods along with higher EE covered by DNS and lower EE by the asymptotic model allows for this range of the heat transfer results. For stress-free boundaries, the relation Nu1(RaE4/3)αNu-1 \propto (Ra E^{4/3} )^{\alpha} has the dissipation-free scaling of α=3/2\alpha = 3/2 for all E107E \leq 10^{-7}. This is directly related to a geostrophic turbulent interior that throttles the heat transport supplied to the thermal boundary layers. For no-slip boundaries, the existence of ageostrophic viscous boundary layers and their associated Ekman pumping yields a more complex 2D surface in Nu(E,Ra)Nu(E,Ra) parameter space. For E<107E<10^{-7} results suggest that the surface can be expressed as Nu1(1+P(E))(RaE4/3)3/2Nu-1 \propto (1+ P(E)) (Ra E^{4/3} )^{3/2} indicating the dissipation-free scaling law is enhanced by Ekman pumping by the multiplicative prefactor (1+P(E))(1+ P(E)) where P(E)5.97E1/8P(E) \approx 5.97 E^{1/8}. It follows for E<107E<10^{-7} that the geostrophic turbulent interior remains the flux bottleneck in rapidly rotating Rayleigh-B\'enard convection. For E107E\sim10^{-7}, where DNS and asymptotic simulations agree quantitatively, it is found that the effects of Ekman pumping are sufficiently strong to influence the heat transport with diminished exponent α1.2\alpha \approx 1.2 and Nu1(RaE4/3)1.2Nu-1 \propto (Ra E^{4/3} )^{1.2}.Comment: 9 pages, 14 figure

    The effects of Ekman pumping on quasi-geostrophic Rayleigh-Benard convection

    Full text link
    Numerical simulations of 3D, rapidly rotating Rayleigh-Benard convection are performed using an asymptotic quasi-geostrophic model that incorporates the effects of no-slip boundaries through (i) parameterized Ekman pumping boundary conditions, and (ii) a thermal wind boundary layer that regularizes the enhanced thermal fluctuations induced by pumping. The fidelity of the model, obtained by an asymptotic reduction of the Navier-Stokes equations that implicitly enforces a pointwise geostrophic balance, is explored for the first time by comparisons of simulations against the findings of direct numerical simulations and laboratory experiments. Results from these methods have established Ekman pumping as the mechanism responsible for significantly enhancing the vertical heat transport. This asymptotic model demonstrates excellent agreement over a range of thermal forcing for Pr ~1 when compared with results from experiments and DNS at maximal values of their attainable rotation rates, as measured by the Ekman number (E ~ 10^{-7}); good qualitative agreement is achieved for Pr > 1. Similar to studies with stress-free boundaries, four spatially distinct flow morphologies exists. Despite the presence of frictional drag at the upper and/or lower boundaries, a strong non-local inverse cascade of barotropic (i.e., depth-independent) kinetic energy persists in the final regime of geostrophic turbulence and is dominant at large scales. For mixed no-slip/stress-free and no-slip/no-slip boundaries, Ekman friction is found to attenuate the efficiency of the upscale energy transport and, unlike the case of stress-free boundaries, rapidly saturates the barotropic kinetic energy. For no-slip/no-slip boundaries, Ekman friction is strong enough to prevent the development of a coherent dipole vortex condensate. Instead vortex pairs are found to be intermittent, varying in both time and strength.Comment: 20 pages, 10 figure

    Social Emotional Learning: A Professional Development Series for Teachers

    Get PDF
    In the past two years, we have experienced unprecedented times throughout the COVID-19 pandemic. As students were forced into distance learning, they were missing out on the opportunity to grow their social and emotional skills in person with their peers. This capstone paper and project seek to answer the question, “How can we as teachers incorporate social emotional learning on a regular basis to create meaningful progress for students?” As we return to regular in person learning, it is so important for teachers and students to focus on social and emotional learning. Although academics are what most people think of when they picture school, students also need social emotional learning to become successful students. Along with math, reading, and other academic subjects, students need to learn important skills including self-awareness, self-management, social awareness, relationship skills, and responsible decision making. As students grow in their social emotional skills and learn to manage their behaviors and emotions, it creates a positive classroom environment for learning. The professional development sessions were created for teachers, reviewing the main concepts from Kuyper’s Zones of Regulation, MindUp, and Purposefull People by Character Strong. These are a few of the many social emotional curricula and concepts that exist, however they each include important concepts that can be used in the classroom when working with students on social and emotional skills. The goal of the professional development is for the teacher participants to leave the sessions feeling increased knowledge of the social emotional concepts discussed, and be more prepared to implement them with their students
