This paper addresses two central problems in simulation methodology: the generation of conjidence intervals for the steady state means of the output sequences and the sequential use of these conjidence intervals to control the run length. The variance of the sample mean of a covariance stationary process is given approximately by p(O)lN, where p( f ) is the spectral density at frequency f and N...

From a mathematical point of view the fundamental challenge of computational fluid dynamics arises from nonlinear terms in the governing dynamical equations, of which the prototype is the flow velocity ~u and its advection (~u· ~ ∇)~u. It is commonly known that the most accurate and efficient method to compute the gradient (~ ∇) part is the spectral method, in which ~u(~x) is approximated at ea...

Electron paramagnetic resonance imaging (EPRI) can be modeled by the forward projection of a 4D synthetic spectral-spatial phantom. We developed a simulation tool for EPRI and carried out a quantitative comparison between simulation and experiment, focusing on the signal and noise characteristics. The signal height in the simulation was compared to that in the experimental projections at gradie...

Introduction: Purkinje Cell (PC) output displays a complex firing pattern consisting of high frequency sodium spikes and low frequency calcium spikes, and disruption in this firing behavior may contribute to cerebellar ataxia. Riluzole, neuroprotective agent, has been demonstrated to have neuroprotective effects in cerebellar ataxia. Here, the spectral analysis of PCs firing in control, 3-acety...

EasySpin, a computational package for spectral simulation and analysis in EPR, is described. It is based on Matlab, a commercial technical computation software. EasySpin provides extensive EPR-related functionality, ranging from elementary spin physics to data analysis. In addition, it provides routines for the simulation of liquid- and solid-state EPR and ENDOR spectra. These simulation functi...

satellite imagery was used as a rapid and spatially explicit method to delineate crop residue cover and to estimate the use and intensity of conservation tillage. the potential of multispectral high-spatial resolution of worldview-2 local data was evaluated using 11 satellite spectral indices and linear spectral unmixing analysis (lsua). experimental plots were examined; residue cover was measu...
