With the advent of efficient algorithms and fast computers for training neural networks, it is now feasible to employ neural network predictors in the generalized likelihood ratio (GLR) test for the purpose of detecting abrupt nonstationary changes in the dynamics of a time series. We examine some of the special issues involved and present some simulation results validating the new hybrid algor...

The authors propose a bibliometric model for discarding journal volumes at academic libraries, i.e., removal to offsite storage as part of the library's serials collection. The method is based on the volume as the unit of measurement and on user satisfaction with given titles. The discarding age, calculated for each volume, from the year of publication to the year of decision to discard, is dep...

were nonstationary at first positions for the ingroup at P = 0.01 using the chi-square test in PAUP*. The chi-square test in PAUP∗ appears to do a good job of identifying the worst offenders and although crude, is effective for a large data set when analyzing individual genes. We certainly anticipate that as more refined tests of stationarity are implemented (e.g., Foster, 2004), discrimination...

on the onset of triple-diffusive convection in a horizontal layer of nanofluid heated from below and salted from above and below is studied both analytically and numerically. the effects of thermophoresis and brownian diffusion parameters are also introduced through buongiorno model in the governing equations. by using linear stability analysis based on perturbation theory and applying normal m...

in this paper, we study projected non-stationary simultaneous it-erative reconstruction techniques (p-sirt). based on algorithmic op-erators, convergence result are adjusted with opial’s theorem. the advantages of p-sirt are demonstrated on examples taken from to-mographic imaging.

in this paper, we investigate the concept of topological stationary for locally compact semigroups. in [4], t. mitchell proved that a semigroup s is right stationary if and only if m(s) has a left invariant mean. in this case, the set of values ?(f) where ? runs over all left invariant means on m(s) coincides with the set of constants in the weak* closed convex hull of right translates of f. th...
