Probabilistic Approach for Budgeting in Portfolio of Projects

This paper presents a mathematical model for calculating the budgetary impact of increasing the required confidence level in a probabilistic risk assessment for a portfolio of projects. The model provides a rational approach for establishing a probabilistic budget for an individual project in such a way that the budget for a portfolio of projects will meet a required confidence level. The use of probabilistic risk assessment in major infrastructure projects is increasing to cope with major cost overruns and schedule delays. The outcome of the probabilistic risk assessment is often a distribution for project costs. The question is at what level of confidence (i.e., the probability that budget would be sufficient given the cost distribution) should be used for establishing the budget. The proposed method looks at a portfolio of such projects being funded by the same owner. The owner can establish a target probability with respect to its annual budget. The model can help the owner establish confidence level for individual projects and also examine the effect of changing the confidence level of the portfolio budget on the budget and the confidence level of individual projects. The paper is relevant to practitioners because it provides a methodology for establishing confidence levels by the owner agencies in the emerging field of cost risk assessment for infrastructure projects. A numerical example is provided using actual transit project data to demonstrate the model application.     

Volume-Conservative Nonlinear Flood Routing

The nonlinear Muskingum and diffusion wave methods for flood routing are deduced from a conservative modified-advection equation as an approximation of the one-dimensional Saint-Venant equations. The modified-advection equation has the kinematic wave speed and attenuation parameter as functions of discharge, which can be derived for the particular averaged geometry for the cross section and hydraulic properties of the reach. The nonlinear Muskingum and diffusion wave methods also include any uniformly distributed time-dependent lateral inflow along the river and are valid for any Froude number. The methods are discussed in relation to corresponding methods derived recently for Muskingum routing and for diffusion wave routing. Numerical experiments on a synthetic river including extensive flood plains show that the proposed nonlinear Muskingum method is highly accurate compared with a full solution of the Saint-Venant equations. The deterioration of accuracy with decreasing bed gradient is highlighted for cases with and without lateral inflow.

Theory of Plastic Sand Flow with Fluid Pressure Effect

Fundamental principles of elastic–plastic mechanics of soils and rocks are given on the base of the original publications. The solid friction and dilatancy effects are included in the nonstandard form of nonassociative rule of plastic flow. The resulting hyperbolic system of equations is represented for a plane case. The slip surfaces are assumed to be jump tangential discontinuities of a velocity field. The possibility of limit equilibrium at slip surfaces is accounted for. The attempts to account for grain rotations, permitting study of slip surface structure, are discussed. The Biot–Frenkel model of interpenetrating continua is developed for plastic flow of porous saturated matrix. In this case the solid matrix state is determined by the effective stresses and pore pressure diffusion happens in plastically flowing matrix. To illustrate the theory possibilities, solutions for failure and mass sand flow, driven by the pore pressure gradient, are selected. They are important especially for oil/gas reservoirs with a weak matrix, typical for offshore geology.

Completely Incinerable Extractants for the Nuclear Industry - A Review

The paper is a review of the properties of the new extractants investigated in the author's laboratory during the last two decades for the chemical separations needed for the nuclear fuel cycle. The choice of the new extractants takes into account the desire to limit as much as possible the process waste. Four topics are discussed. I) The possible replacement of TBP by N,N-dialkylamides in the classical PUREX process {U and Pu recovery from irradiated nuclear fuels), or for other chemical separations. 2) The possible use of substituted 1,3-diamides propane for the decommissioning of a nuclear wastes containing Am(III), Cm(III) or other actinides in the tetra or hexavalent state. 3) The soft donor extractants for trivalent actinide-lanthanide group separations. 4) The exploration to find new extractants for separation of all the actinides (III, IV, VI) from the spent nuclear fuels, using only one extraction cycle, necessitating /?, y heavy shielding. The trivalent lanthanides must remain in the effluent for this separation.
