Soil moisture content changes caused by rainfall and other factors can significantly affect slope stability potentially lead to geological disasters, such as landslides debris flows. However, conventional finite element methods for strength reduction do not consider the impact of water on stability. This paper examines classical reducing double coefficient then introduces a novel approach using...

For the theoretical study of X and extreme-UV spectra ions in plasmas, quantum mechanics brings more detailed results than statistical physics. However, it is impossible to handle individually billions levels that must be taken into account order properly describe hot plasmas. Such can gathered electronic configurations or superconfigurations (groups configurations) corresponding calculations r...

Efficient numerical techniques for multivariable system identification and model reduction are investigated. The techniques are implemented in the system identification and model reduction toolboxes based on the Fortran 77 Subroutine Library in Control Theory (SLICOT). Besides highly performant Fortran drivers and computational routines, these toolboxes provide MATLAB or Scilab interfaces, impl...

A resolution complete optimal kinodynamic motion planning algorithm is presented and described as a generalized label correcting (GLC) method. In contrast to related algorithms, the GLC method does not require a local planning subroutine and benefits from a simple implementation. The key contributions of this paper are the construction and analysis of theGLC conditions which are the basis of th...

The paper presents performance results for some components of the new, public-domain version of the SLICOT library (Subroutine Library in Control Theory), in comparison with equivalent computations performed by some Matlab functions included in the Control Toolbox. SLICOT incorporates the new algorithmic developments in numerical linear algebra, implemented in the state-of-the-art software pack...

This paper deals with fault location on three-terminal power line. The fault locator is considered as associated with the line protective relay, which communicates with the relays from the remaining line terminals and receives from them the phasors of measured threephase currents. Three subroutines of the fault location algorithm are formulated and an issue of selecting the subroutine, which is...

Several logics for reasoning under uncertainty distribute probabil ity mass over sets in some sense These include probabilistic logic Dempster Shafer theory other logics based on belief functions and second order probabilistic logic We show that these logics are in stances of a certain type of linear programming model typically with exponentially many variables We also show how a single linear ...

In this paper a tool is presented for the development of numerical libraries for an object-oriented environment. The development of libraries has become more complicated as libraries have become larger and the subroutines have become more complex. In the object{oriented environment this development is further complicated by the object interface which usually resides between the application and ...

Previous research on landowner willingness to retire land into the Conservation Reserve Program (CRP) is based on cross-sectional data prior to 2002. Using enrollment data on a CRP subprogram from 1998 to 2010 we find that incentives matter more for pasture than cropland, and we find that counties producing cattle respond more strongly to current incentives. We also see an idiosyncratic lack of...
