    Road User Charging ā€“ Pricing Structures.

    No full text
    This project considers the extent to which the public could cope with complex price or tariff structures such as those that might be considered in the context of a national congestion pricing scheme. The key elements of the brief were: ā€¢ to review existing studies of road pricing schemes to assess what information and evidence already exists on the key issues; ā€¢ to identify what can be learned about pricing structures from other transport modes and other industries and in particular what issues and conclusions might be transferable; ā€¢ to improve the general understanding of the relationship between information and peopleā€™s ability to respond; and ā€¢ to recommend what further research would be most valuable to fill evidence gaps and enable conclusions to be drawn about an effective structure

    Version: as accepted for publication.BACKGROUND: The purpose of this study was to characterize the physiological demands of a riding session comprising different types of recreational horse riding in females. METHODS: Sixteen female recreational riders (aged 17 to 54 years) completed an incremental cycle ergometer exercise test to determine peak oxygen consumption (VOā‚‚peak) and a 45-minute riding session based upon a British Horse Society Stage 2 riding lesson (including walking, trotting, cantering and work without stirrups). Oxygen consumption (VOā‚‚), from which metabolic equivalent (MET) and energy expenditure values were derived, was measured throughout. RESULTS: The mean VOā‚‚ requirement for trotting/cantering (18.4 Ā± 5.1 mlĀ·kgā»Ā¹Ā·minā»Ā¹; 52 Ā± 12% VOā‚‚peak; 5.3 Ā± 1.1 METs) was similar to walking/trotting (17.4 Ā± 5.1 mlĀ·kgā»Ā¹Ā·minā»Ā¹; 48 Ā± 13% VOā‚‚peak; 5.0 Ā± 1.5 METs) and significantly higher than for work without stirrups (14.2 Ā± 2.9 mlĀ·kgā»Ā¹Ā·minā»Ā¹; 41 Ā± 12% VOā‚‚peak; 4.2 Ā± 0.8 METs) (P = .001). CONCLUSIONS: The oxygen cost of different activities typically performed in a recreational horse riding session meets the criteria for moderate intensity exercise (3-6 METs) in females, and trotting combined with cantering imposes the highest metabolic demand. Regular riding could contribute to the achievement of the public health recommendations for physical activity in this population

    Several areas that arise from the system integration issue were examined. Intersystem analysis is discussed as it relates to software development, shared data bases and interfaces between TEMPUS and PLAID, shaded graphics rendering systems, object design (BUILD), the TEMPUS animation system, anthropometric lab integration, ongoing TEMPUS support and maintenance, and the impact of UNIX and local workstations on the OSDS environment

    The results of the first phase of Research on an Expert System for Database Operation of Simulation/Emulation Math Models, is described. Techniques from artificial intelligence (AI) were to bear on task domains of interest to NASA Marshall Space Flight Center. One such domain is simulation of spacecraft attitude control systems. Two related software systems were developed to and delivered to NASA. One was a generic simulation model for spacecraft attitude control, written in FORTRAN. The second was an expert system which understands the usage of a class of spacecraft attitude control simulation software and can assist the user in running the software. This NASA Expert Simulation System (NESS), written in LISP, contains general knowledge about digital simulation, specific knowledge about the simulation software, and self knowledge

    Past, present and futureā€”sample environments for materials research studies in scattering and spectroscopy; a UK perspective

    Get PDF
    Small angle x-ray scattering and x-ray absorption fine structure are two techniques that have been employed at synchrotron sources ever since their inception. Over the course of the development of the techniques, the introduction of sample environments for added value experiments has grown dramatically. This article reviews past successes, current developments and an exploration of future possibilities for these two x-ray techniques with an emphasis on the developments in the United Kingdom between 1980ā€“2020
