Defining Uncertainty: A Conceptual Basis for Uncertainty Management in Model-Based Decision Support

Walker, W.E. (author), Harremoës, P. (author), Rotmans, J. (author), Van der Sluijs, J.P. (author), Van Asselt, M.B.A. (author), Janssen, P. (author), Krayer von Krauss, M.P. (author)

The aim of this paper is to provide a conceptual basis for the systematic treatment of uncertainty in model-based decision support activities such as policy analysis, integrated assessment and risk assessment. It focuses on the uncertainty perceived from the point of view of those providing information to support policy decisions (i.e., the...

Ecoprofile rays and skates on the Dutch continental shelf and North Sea

Walker, P. (author)

Several species of rays and skates were common in Dutch territorial waters at the beginning of the century and there was a directed fisheries on these species. During the 1930's a decline in landings was seen and shortly after the Second World War there were few rays left on the Dutch continental shelf. At the present time only two species of...

Analysis of 208 US Navy orbits for the satellite 1970-47B at 14th-order resonance

Walker, D.M.C. (author)

The orbit of 1970-47B passed very slowly through 14th-order resonance, and the changes in orbital inclination and eccentricity have been analysed over a four-year period, from January 1977 to January 1981, using 208 US Navy orbits. The analysis has yielded values for three pairs of lumped harmonic coefficients of 14th order, which have...

Individual geopotential coefficients of order 15 and 30, from resonant satellite orbits

King-Hele, D.G. (author), Walker, D.M.C. (author)

The analysis of variations in satellite orbits when they pass through 15th-order resonance (15 revolutions per day) yields values of lumped geopotential harmonies of order 15, and sometimes of order 30. The 15th-order lumped harmonies obtained from 24 such analyses over a wide range of orbital inclinations are used here to determine individual...

Geopotential harmonics of order 15 and 30, from analysis of the orbit of satellite 1971-10B

Walker, D.M.C. (author)

The satellite 1971-l0B passed through exact 15th-order resonance on 1981 March 30, and orbital parameters have been determined at 52 epochs from some 3500 observations using the RAE orbit refinement program, PROP, between 1980 September and 1981 October. The variations in inclination and eccentricity during this time have been analysed, and six...
