Data extrapolation in social sensing for disaster response
… that ""fill-in"" missing pieces. Unlike trend-extrapolation methods, we focus on prediction in disaster scenarios where disruptive trend changes occur. A set of prediction heuristics (and a standard trend extrapolation algorithm) are compared that use either predominantly-spatial or …

Using wireless sensors and networks program for chemical particle propagation mapping and chemical source localization
… mapping is built using interpolation and extrapolation methods. The interpolation method get the chemical particle path through the sensors, and the extrapolation method get the chemical particle beyond the sensors. Both of them compose of the mapping in the whole considered area. Second, …

Experimental characterization of condensation behavior for metastable carbon dioxide
… of the Wilson line, and the accuracy of two methods for determining metastable properties: spline-based extrapolation and equation of state (EOS) based extrapolation using the Span and Wagner EOS. The experiment consists of a heated charge tank and an optically accessible instrumented …

Topics on spatially high-order accurate methods and preconditioning for the Navier-Stokes equations with finite-rate chemistry
… the computational qualities of various spatial methods for the finite-volume solution of the Euler equations are presented. The two-dimensional essentially non-oscillatory (ENO), k-exact, and dimensionally split ENO reconstruction operators are discussed and compared in terms of reconstruction …

Automating Heterogeneous Parallelism in Numerical Differential Equations
… computing is an amalgamation of numerical methods and computer science. Developments in numerical analysis have allowed stable and accurate numerical schemes, whereas computer algorithms have been successfully adopted to standard multicore systems of today, enabling parallelism. Combining …

Essays on Labor Market Institutions
… design with regression discontinuity extrapolation methods. This strategy allows us to estimate treatment effects that include elections that win by large margins of support. We show that unionization decreases an establishment's employment and likelihood of survival. We hypothesize …

High Accuracy Fitted Operator Methods for Solving Interior Layer Problems
Fitted operator finite difference methods (FOFDMs) for singularly perturbed problems have been explored for the last three decades. The construction of these numerical schemes is based on introducing a fitting factor along with the diffusion coefficient or by using principles of the non-standard …

Reliability based live loads for structural assessment of bridges on heavy-haul railway lines
… in speed during train crossing. Different extrapolation techniques were used to obtain load effects from the same block maxima data. It was shown that the normal, GEV and Bayesian extrapolation methods give load effects within 1% of each other with the normal extrapolation being marginally …

Evaluation of Scale Effects in Load-Displacement Response of Drilled Shafts Based on Field Load Tests
… correlations. In this study, two existing extrapolation methods were evaluated and a new one is being proposed for further evaluation to predict fully mobilized load-displacement behavior from partially mobilized records. Each proposed method of extrapolation will be presented and …
