A Generalized Two-level Graphical Forecast Scheme
نویسنده
چکیده
An arbitrary isobaric surface and the level of non-divergcnce constitute the two levels of the proposrd model. The vorticity equation consistent with the quasi-geostrophic assumptions is applied at two levels. The thermodynamic energy equation for adiabatic motion is applied to the layer hetwecn the two levrls. A parabolic profile for the vertical motion is assumed. The vertical motion is e1imin:itc.d betwrc.11 the vorticity and the thermodynamic energy equations to obtain prognostic equations. The prognostic cqnations are solved by a gcrleralized graphical forecast scheme of successive approximations. Forccast:: and forcJc;tst errors in :I selected mrteorologicd situation are discussed.

Model Predictive Control of Distributed Energy Resources with Predictive Set-Points for Grid-Connected Operation
This paper proposes an MPC - based (model predictive control) scheme to control active and reactive powers of DERs (distributed energy resources) in a grid - connected mode (either through a bus with its associated loads as a PCC (point of common coupling) or an MG (micro - grid)). DER may be a DG (distributed generation) or an ESS (energy storage system). In the proposed scheme, the set - poin...
متن کاملMonitoring Processes that Wander Using Integrated Moving Average Models
Often the least appropriate assumption in traditional control charting technology is that process data constitute a random sample. In reality most process data are correlated—either temporally, spatially, or due to nested sources of variation. One approach to monitoring temporally correlated data uses a control chart on the forecast errors from a time series model of the process with, possibly,...
متن کاملAn Efficient Threshold Verifiable Multi-Secret Sharing Scheme Using Generalized Jacobian of Elliptic Curves
In a (t,n)-threshold secret sharing scheme, a secret s is distributed among n participants such that any group of t or more participants can reconstruct the secret together, but no group of fewer than t participants can do. In this paper, we propose a verifiable (t,n)-threshold multi-secret sharing scheme based on Shao and Cao, and the intractability of the elliptic curve discrete logar...
متن کامل8 . 11 Examples of Graphical Forecast Editor Use in Operations during 2003
In the last few years, the Graphical Forecast Editor and supporting software (called the GFESuite or GFE) has become the primary tool that operational forecasters at the National W eather Service (NW S) off ices use to create and edit their gridded forecast fields (LeFebvre et al., 2003). The GFESuite provides a wide range of tools and capabilities for this purpose, but it has been left up to t...
متن کاملTractable Algorithms for Approximate Nash Equilibria in Generalized Graphical Games with Tree Structure
We provide the first fully polynomial time approximation scheme (FPTAS) for computing an approximate mixedstrategy Nash equilibrium in graphical multi-hypermatrix games (GMhGs), which are generalizations of normal-form games, graphical games, graphical polymatrix games, and hypergraphical games. Computing an exact mixed-strategy Nash equilibria in graphical polymatrix games is PPADcomplete and ...
