Abstract The MICROSCOPE mission aims to test the weak equivalence principle (WEP) in orbit with an unprecedented precision of 10 −15 on Eötvös parameter thanks electrostatic accelerometers board a drag-free micro-satellite. is determined by statistical errors, due environment and instrument noises, systematic errors which this paper devoted. Systematic error sources can be divided into three ca...

Background: Medical errors are those errors or mistakes committed by healthcare professionals due to errors of omission, errors in planning, and errors of execution of a planned healthcare action whether or not it is harmful to the patient. Medical error in hospitals increases morbidity and mortality and decreases patient satisfaction and hospital productivity. This study aimed to determine the...

Introduction: Human errors are the cause of many accidents, including industrial and medical, therefore finding out an approach for identifying and reducing them is very important. Since no study has been done about human errors in the dental field, this study aimed to identify and assess human errors in postgraduate endodontic students of Kerman University of Medical Sciences by using the SHER...

Errors in health care services may cause irreversible harm in some cases. Medical errors are a threat to the welfare and health of the patient and their family and should be prevented. The majority of medical errors have little impact on human health, but some of them cause huge losses. This report describes a case of laboratory error in amniocentesis during pregnancy in which uncertain test re...

This paper presents experimental analysis of wheeled mobile robots. Mathematical modelling of the mobile robot is presented. The mobile robots consist of an omni-directional and three differential drive mobile robots are tested and moved in given trajectories and the systematic errors of the robots are determined. A new method for omni-direction mobile robot was introduced in which the robot wa...

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. M...
