Color errors in scanners arise from two sources: the non-colorimetric nature of the scanner sensitivities and the measurement noise. Several measures of goodness have been used to evaluate scanners based on these errors. In this paper, the trustworthiness of these measures is studied through simulations. A new measure incorporating both the above sources of errors and providing excellent agreem...

Abstract. A survey of the North Celestial Pole region using the RATAN-600 radio telescope at five frequencies in the range 2.3 to 21.7 GHz is described. Sources were chosen from the NVSS catalogue. The flux densities of 171 sources in the Declination range +75◦ to +88◦ are presented; typical flux density errors are 5-10 percent including calibration errors. About 20 percent of the sources have ...

spatiality assessment of groundwater pollution is very important to determine water quality condition, pollution sources and management decisions. in this case, gis and geostatistics methods can be useful tools. spatiality of groundwater quality parameters, in relation with various land uses, can be very extremely. therefore water samples from 52 wells in the kurdan area were analyzed in this s...

BACKGROUND Record linkage is the process of bringing together related records that have been compiled separately [1]. Many types of studies have been conducted that have used different methods and approaches to link medical records obtained from heterogeneous data sources. For example, the use of administrative data for research purposes has led to considerable interest in computerized methods ...

This paper deal with highly-reliable integrated circuits for ground and space applications especially strong against soft errors. In the terrestrial region, neutrons and alpha particles are main sources to cause soft errors. They flip contents of storage cells such as SRAMs and flip flops on a semiconductor chip. Soft errors must be considered for semiconductor chips for security, automotive, a...

Spatial baseline determination is a key technology for interferometric synthetic aperture radar InSAR missions. Based on the intersatellite baseline measurement using dual-frequency GPS, errors induced by InSAR spatial baseline measurement are studied in detail. The classifications and characters of errors are analyzed, and models for errors are set up. The simulations of single factor and tota...

The evaluation of measurement uncertainty is complex as there are a variety of sources of errors and variation. The task of combining all the sources of errors, according to the guidelines in GUM [1], to come up with an uncertainty budget is not an easy one. There is no single uncertainty statement that can be generally applied to all CMMs. The uncertainty for every individual CMM is specific t...
