Resolution independent residuals ) ( / ) ( o c o I I I σ ς − = should not show any discontinuities, when plotted against the resolution . The density of reflections per resolution range, however, changes with resolution, which limits the information value from these plots. Residuals plotted against ranked resolution values, should be uniform and are easy to interpret. These plots of individual ...

INTRODUCTION Our ability of detecting or identifying stimuli is limited and we are susceptible to different kinds of illusions or ‘mistakes’. Perceptual limits are often investigated by using rapid serial visual presentation (RSVP) experiments. In a typical RSVP experiment stimuli are sequentially presented at a rate of 6 to 20 items per second and observers are asked to detect or identify a ta...

Glucose monitoring has become an integral part of diabetes care but has some limitations in accuracy. Accuracy may be limited due to strip manufacturing variances, strip storage, and aging. They may also be due to limitations on the environment such as temperature or altitude or to patient factors such as improper coding, incorrect hand washing, altered hematocrit, or naturally occurring interf...

background and objectives: for total analytical error, imprecision (sd) and bias, performance goals for laboratory tests have most often been developed. a total analytical error goal requires that the combination of errors from all sources (random and systematic errors) be within some acceptable limit. materials and methods: fifty vials of sodium and potassium standards (sandos company) were ch...
