Simulation of wake vortex effects for UAVs in close formation flight
Full text linkThis paper addresses the development of multiple UAV deployment simulation
models that include representative aerodynamic cross-coupling effects.
Applications may include simulations of autonomous aerial refuelling and
formation flying scenarios. A novel wake vortex model was developed and
successfully integrated within a Matlab/Simulink simulation environment. The
wake vortex model is both sufficiently representative to support studies of
aerodynamic interaction between multiple air vehicles, and straightforward
enough to be used within real time or near real time air-to-air simulations. The
integration process is described, and simulation results of a two vehicles
formation flight are presented
The Picture and the Letter: Male and Female Creativity in James Joyce’s 'Finnegans Wake'
Full text linkAll Joyce’s works both implicitly and explicitly contain theories of artistic creation. The central theme of this dissertation concerns the separate roles assigned to male and female in descriptions of the creative process in Finnegans Wake, and additionally to assess the gender-related issues surrounding the Wakean cycle of creativity. The latter requirement unites two modes of reading: namely an elucidation of what is overtly present in Finnegans Wake regarding creative acts, together with an assessment of the implications of what is absent or repressed. The argument seeks to demonstrate a new understanding of the cycle of Wakean creativity by examining recurring references to a picture motif and its relationship to the more widely appreciated letter motif. It also examines the feminine reverse of the masculine structure of the cyclic reproduction of HCE, and in particular the ways in which Joyce simultaneously produces and undermines those cycles. The thesis shows that reproduction of the unifying masculine logos and its accompanying control of desire for the purposes of social domination is offset by a correlated requirement for resisting the logos based upon difference and free love
Evaluating the Government as a Source of Systemic Risk
Full text linkIn the wake of the financial crisis, the Dodd–Frank Act established the Financial Stability Oversight Council (FSOC) and the Office of Financial Research (OFR) to address the concern that policymakers lacked sufficient data to anticipate emerging threats to financial stability. Although most discussions about systemic risk have focused on the private sector, the U.S. Federal Government is the world’s largest and most interconnected financial institution, and through its activities — as a banker, rule-maker and regulator — represents a major source of systemic risk. This paper makes the qualitative and quantitative case that the government is a significant source of such risks, discusses the nature of the risks and offers suggestions for how the OFR, through its data initiatives and analyses, could help illuminate and mitigate those risks
Sars-Cov-2/Covid-19 [Coronavirus] Global Scientific Research and How it Impacts Workplace Health Management and Health Services, Including Policy Implications
No full textBackground/Objectives The research rationale is that many economic, policy, and government implications result from the COVID-19 pandemic. Author published a literature review on COVID-19 research specific to Australia including policy and media releases. This Australian scientific literature assessed the social impact, government, and policy implications. This manuscript expands on previous research by assessing global pandemic policy specifically in relation to workplace health management, health services and systems. Methods A search strategy was created using the MeSH Browser. The MeSH (Medical Subject Headings) is the NLM controlled vocabulary thesaurus used for indexing articles for PubMed and is at; https://www.ncbi.nlm.nih.gov/mesh. (((((("SARS-CoV-2"[Mesh])) OR "COVID-19"[Mesh]) OR "Coronavirus"[Mesh]) AND "Policy"[Mesh]). The following individual text words were added to the search string – ‘health services’; - ‘workforce’; - ‘health systems’ in order to quantify the extent of literature pertaining to workplace health management. Results The PubMed Mesh search performed retrieved 2934 articles. Adding individual text words resulted in the following retrievals; health services - 926 retrievals, workforce – 74 retrievals, health systems – 414 retrievals. Conclusions The impact of a pandemic upon workforce services is immense. It relates to variations as a result of shutdowns and adapted essential service provisions. This results in reduced screening or current testing strategies, changes to other routine procedures/services, immunizations/vaccinations and/or reduced treatment for patients with pre-existing diseases. A rapid shift in service delivery with increased usage of digital technologies & e- health in particular in high-income countries is evident, with low and middle-income countries somewhat compromised by poorer infrastructure
Learning theories and interprofessional education: a user's guide
Full text linkThere is increasing interest in the theoretical underpinning of interprofessional education (IPE) and writers in this field are drawing on a wide range of disciplines for theories that have utility in IPE. While this has undoubtedly enriched the research literature, for the educational practitioner, whose aim is to develop and deliver an IPE curriculum that has sound theoretical underpinnings, this plethora of theories has become a confusing, and un-navigable quagmire. This article aims to provide a compass for those educational practitioners by presenting a framework that summarizes key learning theories used in IPE and the relationship between them. The study reviews key contemporary learning theories from the wider field of education used in IPE and the explicit applications of these theories in the IPE literature to either curriculum design or programme evaluation. Through presenting a broad overview and summary framework, the study clarifies the way in which learning theories can aid IPE curriculum development and evaluation. It also highlights areas where future theoretical development in the IPE field is required
Cost-justifying usability: an update for the internet age
No full textYou just know that an improvement of the user interface will reap rewards, but how do you justify the expense and the labor and the time-guarantee a robust ROI!-ahead of time? How do you decide how much of an investment should be funded? And what is the best way to sell usability to others? In this completely revised and new edition, Randolph G. Bias (University of Texas at Austin, with 25 years' experience as a usability practitioner and manager) and Deborah J. Mayhew (internationally recognized usability consultant and author of two other seminal books including The Usability Engine
Cognitive Theory and the Selling of the Flat Tax
Full text linkIn this article, Professor Deborah A. Geier brings to bear the insights of Professor Edward J. McCaffery, regarding the interaction of cognitive theory and the tax world, to the flat tax proposal. The article explores how the perceptual biases described by Professor McCaffery might affect both taxpayers\u27 impressions of the contours of the proposed tax base and their behavioral reponses to the same incentive. The author warns that any errors in her application of Professor McCaffery\u27s work to the flat tax are entirely her own

Wake Vortex Modelling and Simulation for Air Vehicles in Close Formation Flight
Full text linkThe aim of this research is to develop realistic models of aerodynamic cross-coupling
e ects that can be incorporated in real-time or near real-time simulations of Unmanned
Aerial Vehicles (UAVs) in close formation flight. These would permit the assessment of
the risks and issues associated with wake vortex evolution and encounter and the analysis
of their consequences on the design of automatic control systems and the development
of safe and reliable operating procedures. A number of wake vortex modelling
techniques that can be used in formation flight simulations are reviewed. A novel Wake
Vortex Model (WVM) is developed, implemented, verified, validated and successfully
integrated within a Matlab/Simulink simulation environment. The code, named ELL
because it is based on Weissinger’s extended lifting line theory, meets the following
requirements: (i) it is generic and can easily be adapted to accomodate any wing planform
and air vehicle configuration; (ii) it is computationally rapid enough to be used in
real-time or near real-time simulations; (iii) and it is sufficiently representative to support
studies of aerodynamic interaction between multiple air vehicles during formation
reconfiguration and air-to-air refuelling simulations. Simulink test scenarios of two
Aerosonde UAVs are developed to test and validate the use of ELL within simulation
models, and the simulation environment is interfaced with visualisation tools in order
to facilitate the evaluation of multiple air vehicle dynamic interaction
