Pupil size in diabetes.
Sympathetic function was studied in 101 diabetic children and 102 age and sex matched control children, as part of a longitudinal study of the evolution of microvascular disease in the population of diabetic children and adolescents in Avon County. The median (range) age of the diabetic population was 13.5 (6.0-17.2) years, the duration of diabetes was 4.0 (0.4-13.9) years, and glycated haemogl...
متن کاملPupil Size and Mental Load
This experiment explores whether the size of human pupil dilation is a measure that can discriminate between easier and harder intellectual tasks undertaken by the participant when information is displayed on a computer monitor. While it has been previously found that a participant’s pupil dilation will be larger during harder intellectual tasks, these experiments have not generally been conduc...
متن کاملSample size estimation in epidemiologic studies
This review basically provided a conceptual framework for sample size calculation in epidemiologic studies with various designs and outcomes. The formula requirement of sample size was drawn based on statistical principles for both descriptive and comparative studies. The required sample size was estimated and presented graphically with different effect sizes and power of statistical test at 95...
متن کاملSystem and measurement method for binocular pupillometry to study pupil size variability
BACKGROUND An objective and noninvasive examination of pupil size variability can be used to assess the activity of the autonomous nervous system. We designed a system that enables binocular, fast, and accurate recordings of different types of pupil variabilities, which are synchronous with other biosignals. This type of measurement system is needed to extend the scope of pupillometry applicati...
متن کاملSoftware Size Uncertainty: The Effects of Growth and Estimation Variability
1,2 Abstract— Examination of currently-accepted software cost, schedule, and defect estimation algorithms reveals a common acknowledgment that estimated software size is the single most influential independent variable. Unfortunately, “The most important business decisions about a software project are made at the time of minimum knowledge and maximum uncertainty.” This includes minimum knowledg...
