Observer error: Are medical students good observers?

Technology and Health Care, 2012
Observer error affects virtually all aspects of medicine. Our objective was to find a way to reduce it among clinical students. A minority need to be shown how to observe. A classroom exercise, repeated 6 times on separate days, using different simple objects, more than doubled the mean score on observation of visible properties of objects by a class ...

Nonlinear Observer Design by Observer Error Linearization

SIAM Journal on Control and Optimization, 1989
The paper discusses the following problem. Given a nonlinear control system \(\dot x=f(x,u)\), \(y=h(x)\), when does there exist a coordinate transformation \(z=\phi (x)\), such that in the new coordinates the system takens the form \(\dot z=Az+g(y,u)\), \(y=Cz\), where the appropriately dimensioned matrices A and C are in observer canonical form (or ...

Observer error in serial radiography

Tubercle, 1956
Summary 500 pairs of chest radiographs of patients attending a chest clinic were examined independently by two physicians and a radiologist. The films were assessed as showing no change, improvement or deterioration. There was agreement in 424 (85 per cent).

Observational Errors

Abstract Experimentalists frequently refer to sources of error, the factors ranging from dirty glassware and contaminated samples to confounding variables and mistaken assumptions that can produce misleading results or faulty conclusions.

Observer Error in Ultrasonic Fetal Cephalometry

Acta Obstetricia et Gynecologica Scandinavica, 1975
Abstract. Although ultrasonic fetal cephalometry gives quite accurate results, a certain degree of observer error must be expected. In a series of duplicate measurements, the magnitude of this error has been assessed. The observer error was lowest when the fetal head was partly engaged in the pelvic inlet, when the midline echo was clearly observed ...
