    A neural network for mining large volumes of time series data

    Get PDF
    Efficiently mining large volumes of time series data is amongst the most challenging problems that are fundamental in many fields such as industrial process monitoring, medical data analysis and business forecasting. This paper discusses a high-performance neural network for mining large time series data set and some practical issues on time series data mining. Examples of how this technology is used to search the engine data within a major UK eScience Grid project (DAME) for supporting the maintenance of Rolls-Royce aero-engine are presented

    Crystalline Polymers with Exceptionally Low Thermal Conductivity Studied using Molecular Dynamics

    Get PDF
    Semi-crystalline polymers have been shown to have greatly increased thermal conductivity compared to amorphous bulk polymers due to effective heat conduction along the covalent bonds of the backbone. However, the mechanisms governing the intrinsic thermal conductivity of polymers remain largely unexplored as thermal transport has been studied in relatively few polymers. Here, we use molecular dynamics simulations to study heat transport in polynorbornene, a polymer that can be synthesized in semi-crystalline form using solution processing. We find that even perfectly crystalline polynorbornene has an exceptionally low thermal conductivity near the amorphous limit due to extremely strong anharmonic scattering. Our calculations show that this scattering is sufficiently strong to prevent the formation of propagating phonons, with heat being instead carried by non-propagating, delocalized vibrational modes known as diffusons. Our results demonstrate a mechanism for achieving intrinsically low thermal conductivity even in crystalline polymers that may be useful for organic thermoelectrics

    Comprehensive rotorcraft analysis methods

    Get PDF
    The development and application of comprehensive rotorcraft analysis methods in the field of rotorcraft technology are described. These large scale analyses and the resulting computer programs are intended to treat the complex aeromechanical phenomena that describe the behavior of rotorcraft. They may be used to predict rotor aerodynamics, acoustic, performance, stability and control, handling qualities, loads and vibrations, structures, dynamics, and aeroelastic stability characteristics for a variety of applications including research, preliminary and detail design, and evaluation and treatment of field problems. The principal comprehensive methods developed or under development in recent years and generally available to the rotorcraft community because of US Army Aviation Research and Technology Activity (ARTA) sponsorship of all or part of the software systems are the Rotorcraft Flight Simulation (C81), Dynamic System Coupler (DYSCO), Coupled Rotor/Airframe Vibration Analysis Program (SIMVIB), Comprehensive Analytical Model of Rotorcraft Aerodynamics and Dynamics (CAMRAD), General Rotorcraft Aeromechanical Stability Program (GRASP), and Second Generation Comprehensive Helicopter Analysis System (2GCHAS)

    What Do You Mean “Truth through Personality”? The Phillips Brooks Definition of Preaching in Historical Context

    Get PDF
    Applying historical-grammatical hermeneutics to the Brooks definition of preaching as truth through personality helps us hear Brooks say that the sum of all truth is Christ. His truth does not stand in indifference to his person as some theologians insisted. By personality Brooks stressed not only the divine person of Christ but also the preacher” character. The contemporary usage of both words, the eight lectures in context, and the colorful history of the 1870” tell the story

    Guiding Preachers in Development of Narrative Skills for Sermon Illustrations

    Get PDF
    Preachers can and must cultivate storytelling skills. They may find help in a Narration Worksheet charting the essential elements of story: plot, setting, character, point of view, and unity. A Plot Movements Worksheet helps keep the narrative flowing from situation, through stress and searching to solution and a new situation

    An Econometric Analysis of Anti-Bullying Program Factors on Bullying in Public American Middle Schools and High Schools

    Get PDF
    This paper seeks to answer the question: “Do typical factors of anti-bullying programs reduce the amount of bullying that takes place in American public middle schools and high schools?” An overview of the literature on bullying and anti-bullying programs is provided. Data from the School Survey on Crime and Safety is analyzed using a probit model. The model is tested for accuracy and the results are analyzed. Parental involvement and out-of-school suspension are found to be significant anti-bullying program factors. Other explanatory variables are also discussed and recommendations for further research are provided
