poverty can have spatial dimensions. while general figures might show the spatial pattern of poverty, there is a need for more detailed examination of this pattern. relying on simple figures of spatial patterns and ranking regions based on them might be misleading. this paper tries to apply spatial analysis methodsm, namely spatial autoregressive models to find out the impacts of space on the h...

Spatial pattern of trees can possibly indicate stand history, population dynamics, and species competition. This research was investigated in the Chahartagh forest reserve, Ardal region, chaharmehal and Bakhtiari Province, Central Zagros forest, and southwest Iranian state. In this study 53 hectare of the study area was selected and perfect inventory.  Information includes the position and kind...

the aim of this study was to investigate the effect of a period of interval training and step taper on weight changes and endurance performance in male rats during puberty. in this experimental study, 40 male wistar rats (3 weeks old) were randomly divided into exercise and control groups. after 6 weeks of incremental interval training, exercise group was divided in to 3 groups of 3-week taper ...

We consider the estimation of covariance a stationary Gaussian process on multi-dimensional grid from observations taken general acquisition domain. derive spectral-norm risk rates for multi-taper estimators. When applied to one-dimensional intervals, these show that Thomson's classical has optimal rates, as they match known benchmarks. also extend existing lower bounds grids and conclude estim...

objectives: to locate the road emergency stations in fars province based on using spatial multi-criteria decision making (delphi method).    methods: in this study, the criteria affecting the location of road emergency stations have been identified through delphi method and their importance was determined using analytical hierarchical process (ahp). with regard to the importance of the criteria...

We investigate the radiation patterns of sharp conical gold tapers, which were designed as adiabatic nanofocusing probes for scanning near-field optical microscopy (SNOM). Field calculations show that only the lowest order eigenmode of such a taper can reach the very apex and thus induce the generation of strongly enhanced near-field signals. Higher-order modes are coupled into the far field at...
