Two decades (2000–2019) of the landfast ice properties in Beaufort Sea region Canadian Arctic were analyzed at 250 m spatial resolution from two sources: (1) monthly maps derived Canada Centre for Remote Sensing Moderate Resolution Imaging Spectroradiometer clear-sky satellite image composites; and (2) Ice Service charts. Detailed comparisons have been conducted extent, water depth at, distance...

Background Over the last decade there has been an increase in healthcare expenditures while at the same time the inequity in distribution of resources has grown. These two issues have urged the researchers to review the determinants of healthcare expenditures. In this study, we surveyed the determinants of health expenditures in Economic Cooperation Organization (ECO) countries.   Methods We us...


 Based on the monitoring data, features of long-term changes evaporation from water surface are determined. Data relatively small evaporators and basins located in different regions Ukraine were processed. It was found that during first part observation period, which began 1950s, had tendency to decrease, while second it increased significantly. To determine factors these changes, existin...

data envelopment analysis (dea) is a mathematical technique to evaluate the performance of firms with multiple inputs and outputs. in conventional dea models, the efficiency scores of decision making units (dmus) with non-negative inputs and outputs are evaluated in a special period of time. however, in the real world there are situations wherein performance of firms must be evaluated in multip...

This paper details a new method of regression for sparsely sampled data sets for use with time-series analysis, in particular the Stratospheric Aerosol and Gas Experiment (SAGE) II ozone data set. Non-uniform spatial, temporal, and diurnal sampling present in the data set result in biased values for the long-term trend if not accounted for. This new method is performed close to the native resol...
