    Vehicle Dynamics Engineers (VDEs) responsible for developing passenger vehicles and Elite Race Drivers were analysed over a 5 year period using telemetry data. Investigations were undertaken in an attempt to identify the most important rate limiting factors for each profession and to develop effective training methods for them. In a preliminary investigation it was found that the VDEs were unable to reliably detect certain changes to a vehicle’s dynamic behaviour despite their high confidence that they were doing so. This result led to the main VDE study where the VDEs were assessed using a Rotary vestibular platform, the RAF Basic Attributes tests and telemetry analysis of their performance while they evaluated changes to a vehicle’s dynamic behaviour. It was found that there was no significant relation between either the Attributes scores or vestibular performance and the VDEs’ ability to discriminate changes to the dynamic behaviour of a vehicle, termed their Evaluation performance. After the VDE’s baseline Evaluation performance was established, they received individual training to improve both their performance at sensing dynamic motion (Perceptual performance) and their consistency and accuracy of controlling vehicle motion (Control performance). The VDEs were then retested to determine the effect of this training on their Evaluation performance. Whereas before training most VDEs scored in the worst Evaluation performance category, after training most scored in the highest Evaluation performance category. A new mathematical technique for analysing telemetry data was developed which allowed us to separately determine the effects of Perceptual performance and Control performance on Evaluation performance. It was found that improving the VDE’s Perceptual performance accounted for all improvements in their Evaluation performance whereas Control performance was unrelated to their Evaluation performance. This finding led to the development of a new Human Factors training program which will be instituted for all Ford’s professional VDEs from 1996 onward. In the Elite race driver study, a mathematical model was developed which allowed us to simulate the effect of altering a driver’s curvature control strategy, which is a key component of a driver’s style, on lap times. It was found that all drivers tested, with the notable exception of 3 times World Formula 1 Champion Jackie Stewart, had inadequate and / or faulty cognitive models for optimising curvature control when compared to our computer simulations. Training the subjects to improve their curvature control model produced substantial objective improvements in performance whereas additional unaided practice produced no improvement. For example a 19 year old N.Z. race driver was trained in one afternoon to lap faster than the current World Touring Car champion using the same vehicle

    0878: The Herald-Dispatch Archives

    Get PDF
    The collection consists of 4 “groupings” of materials that were donated by the Huntington Herald Dispatch when it moved from former offices in Huntington to its newer one in 2021. These groupings include the Herald Dispatch Subject Files, the Name Files, the Photograph Index Files, and the Office Materials (materials boxed up from individual offices in the Herald Dispatch). The first grouping of Subject Files came to the archive in 23 cabinets with 4 drawers each and contains approximately 16,000 folders of subject headings spanning the 1950s to the 2000s. The second grouping of Name Files is in 7 large horizontal filing cabinets with 3 drawers that contain approximately 8,700 files for individuals named in the Herald Dispatch from the same time range as the Subject Files. Both groupings have a folder level index provided below for ease of access. The third grouping in this collection, the Photograph Index Files, contains over a dozen individual plastic boxes and several metal filing cabinets worth of photo negatives taken by Herald Dispatch staff. This part of the selection is not inventoried and is unfortunately not organized into any pattern for locating materials. As such, this portion of the collection is at present not open to the public, but materials can be viewed if advanced notice is given so that archival staff can locate the photographs. The last section consists of all Office Materials found in the process of Special Collections staff gathering materials onsite after the initial collection pickup. These materials do not easily fit into the other classification sections, and are located separately from the rest of the materials. This section of materials includes a variety of sports memorabilia, photographs, sports programs, sports files, WV state documents, Cabell County Board of Education materials, materials relating to the University System of West Virginia, materials on Marshall University, Herald Dispatch administration files, loose articles and designs, VHSs, books, magazines, and other miscellaneous materials

    Computer Chess: From Idea to DeepMind

    Get PDF
    Computer chess has stimulated human imagination over some two hundred and fifty years. In 1769 Baron Wolfgang von Kempelen promised Empress Maria Theresia in public: “I will invent a machine for a more compelling spectacle [than the magnetism tricks by Pelletier] within half a year.” The idea of an intelligent chess machine was born. In 1770 the first demonstration was given.The real development of artificial intelligence (AI) began in 1950 and contains many well-known names, such as Turing and Shannon. One of the first AI research areas was chess. In 1997, a high point was to be reported: world champion Gary Kasparov had been defeated by Deep Blue. The techniques used included searching, knowledge representation, parallelism, and distributed systems. Adaptivity, machine learning and the recently developed deep learning mechanism were only later on added to the computer chess research techniques.The major breakthrough for games in general (including chess) took place in 2017 when (1) the AlphaGo Zero program defeated the world championship program AlphaGo by 100-0 and (2) the technique of deep learning also proved applicable to chess. In the autumn of 2017, the Stockfish program was beaten by AlphaZero by 28-0 (with 72 draws, resulting in a 64-36 victory). However, the end of the disruptive advance is not yet in reach. In fact, we have just started. The next milestone will be to determine the theoretical game value of chess (won, draw, or lost). This achievement will certainly be followed by other surprising developments.Algorithms and the Foundations of Software technolog

    A Holmes and Doyle Bibliography, Volume 7: Audio/Visual Materials, Alphabetical Listing

    This bibliography is a work in progress. It attempts to update Ronald B. De Waal’s comprehensive bibliography, The Universal Sherlock Holmes, but does not claim to be exhaustive in content. New works are continually discovered and added to this bibliography. Readers and researchers are invited to suggest additional content. This volume contains an alphabetical listing of audio-visual materials. Coverage of this material begins around 1994, the final year covered by De Waal's bibliography, but may not yet be totally up-to-date (given the ongoing nature of this bibliography). It is hoped that other titles will be added at a later date

    This bibliography is a work in progress. It attempts to update Ronald B. De Waal’s comprehensive bibliography, The Universal Sherlock Holmes, but does not claim to be exhaustive in content. New works are continually discovered and added to this bibliography. Readers and researchers are invited to suggest additional content. This volume contains all listings in all formats, arranged alphabetically by author or main entry. In other words, it combines the listings from Volume 1 (Monograph and Serial Titles), Volume 3 (Periodical Articles), and Volume 7 (Audio/Visual Materials) into a comprehensive bibliography. (There may be additional materials included in this list, e.g. duplicate items and items not yet fully edited.) As in the other volumes, coverage of this material begins around 1994, the final year covered by De Waal's bibliography, but may not yet be totally up-to-date (given the ongoing nature of this bibliography). It is hoped that other titles will be added at a later date. At present, this bibliography includes 12,594 items

    Specific Challenges of Consumer Protection in Distance Selling Contracts: A Comparison of the Laws of England and Iraq on the Duty to Provide Pre-Contractual Information and the Right of Cancellation

    Get PDF
    This study has covered the duty to provide pre-contractual information and the right of cancellation, the two important key areas of consumer protection in distance selling contracts. These two protection models are invented to rebalance the distance contract in favour of the consumer albeit differently. The duty to provide information rebalances the contract in terms of information, and the right of cancellation provides the distance consumer with an opportunity to rethink the decision about the contract. The study has looked at pertinent laws of distance selling contracts in England and Iraq. In doing so, the study has followed comparative and analytical methodology, whereby strengths and weaknesses, similarities and dissimilarities between the selected laws under a chosen theme are addressed. The aim is to explore problems and loopholes, which may need future amendments, including legal gaps, ambiguity, and incomplete treatment. During the study, specific challenges related to the theme of study are critically analysed. Apparently, the quantity and type of information required, the time and manner of sending information, and the remedy available at the breach are challenges of the information requirements. Challenges of the right of cancellation are the conditions and effects of using the right. The study has concluded that many aspects of protection under both laws need further improvements. The need for changes is more obvious with Iraqi Law than English Law, where distance selling protection has not been recognised yet
