Abstract The Road Weather Management (RWM) Benefit Cost Analysis (BCA) Compendium provides information about benefit cost analyses conducted around the country for specific RWM technologies or operational strategies. The actual project evaluations involve the use of custom spreadsheets developed by the agency or its contractors, or the application of available software tools to the BCA. The Compendium also includes hypothetical cases designed to demonstrate how BCA can be used for a specific RWM technology or operational strategy. FHWA has developed a sketch planning BCA tool —the Tool for Operations Benefit/Cost (TOPS-BC)—for application to TSMO projects, including RWM projects. For the hypothetical cases, TOPS-BC is used to assist in the measurement of benefits and costs and in the calculation of the benefit cost ratio. Each case demonstrates how planners conducted, or could conduct, a BCA on one or more RWM technologies or strategies. There are 17 cases studies presented in the RWM Compendium, and each addresses one or more specific BCA issues or procedures. 17. Key Words 18.

These issues arise prominently in decommissioning and in site remediation, and decisions can be very wide ranging having potentiallly important economic impacts and reaching outside the RWM area. The RWMC Regulators Forum started to address these issues by holding a topical discussion at its meeting in March 2003.

These issues arise prominently in decommissioning and in site remediation, and decisions can be very wide ranging having potentially important economic impacts and reaching outside the RWM area. The relevant issues must be addressed and clearly understood by all stakeholders. There is a large interest in these issues outside the regulatory arena.

  • Response of Parameters of HF Signals at the Long Radio Paths on Solar Activity
    URS I AP -RASC 2019, New Delhi, India, 09 - 15 March 2019 Response of parameters of HF signals at the long radio paths on solar activity Andriy Zalizovski (1, 2) *, Yuri Yampolski (1) , Alexander Koloskov (1, 2), Sergey Kashcheyev (1) , Bogdan Gavrylyik (1) (1) Institute of Radio Astronomy, NASU, Kharkiv, Ukraine; e-mail: [email protected] (2) National Antarctic Scientific Center, Kyiv, Ukraine A technique for multiposition Doppler HF sounding of the ionosphere that use the emission of broadcasting radio-stations as probing signals is developed in the Institute of Radio Astronomy of National Academy of Sciences of Ukraine (IRA NASU) during some last decades. At present the Internet-controlled receiving sites designed by IRA NASU are located in Arctic, Scandinavia, Europe, Africa, and Antarctica. The analysis of HF signal propagation on the super long radio paths is one of the major tasks of this network. This paper discusses the results of the analysis of signal propagation from Europe and Northern America to Antarctica. The signals of time and frequency services were used as probe because of the excellent stability of their parameters. The radiation of RWM (Moscow, carrier frequencies 4996, 9996, and 14996 kHz) and CHU (Ottawa, frequencies 3330, and 7850 kHz) stations are recorded round-the-clock at the Ukrainian Antarctic Station (UAS, 65.25S, 64.27W) Akademik Vernadsky since 2010. Time and spectral analysis of the RWM pulse signals allowed to detect experimentally four different pathways: the direct and reverse paths lying on the great circle, and trajectories outside the great circle formed by focusing along the solar terminator and scattering on the ionospheric irregularities of auroral ovals.

ITU-R TF.768-2 The ITU Radiocommunication Assembly, considering a) the continuing need in all parts of the world for readily available standard frequency and time reference signals that are internationally coordinated; b) the advantages offered by radio broadcasts of standard time and frequency signals in terms of wide coverage, ease and reliability of reception, achievable level of accuracy as received, and the wide availability of relatively inexpensive receiving equipment; c) that Article 33 of the Radio Regulations (RR) is considering the coordination of the establishment and operation of services of standard-frequency and time-signal dissemination on a worldwide basis; d) that a number of stations are now regularly emitting standard frequencies and time signals in the bands allocated by this Conference and that additional stations provide similar services using other frequency bands; e) that these services operate in accordance with Recommendation ITU-R TF.460 which establishes the internationally coordinated UTC time system; f) that other broadcasts exist which, although designed primarily for other functions such as navigation or communications, emit highly stabilized carrier frequencies and/or precise time signals that can be very useful in time and frequency applications, recommends 1 that, for applications requiring stable and accurate time and frequency reference signals that are traceable to the internationally coordinated UTC system, serious consideration be given to the use of one or more of the broadcast services listed and described in Annex 1; 2 that administrations responsible for the various broadcast services included in Annex 2 make every effort to update the information given whenever changes occur.

  • Pupil Premium Report and Strategy Statement
    Hogarth Academy Pupil Premium Report and Strategy Statement In Hogarth Academy we endeavour to fulfil the Pupil Premium Policy set out by the L.E.A.D Academy Trust by deploying the following Trust strategies to diminish the difference in attainment for pupils in receipt of the Pupil Premium funding. • clear, responsive leadership • having a whole-school ethos of attainment for all • addressing behaviours for learning and conduct behaviours that prevent pupils form learning • monitoring and addressing low attendance • facilitating high quality teaching for all through continued professional development of staff. • meeting individual learning needs including those pupils who are the most-able and seemingly need no support • deploying staff effectively, both teaching and support staff • using pupil progress data to inform the planning of interventions and provision. Each Academy reviews the barriers and outcomes for the pupils in receipt of Pupil Premium to understand the strategies that they to use to raise attainment. Each Academy explains their rationale for choosing the strategies and provides a cost breakdown. If you wish this statement to be explained, then please ask to speak with Pupil Premium Leader via the main office.
