introduction: in line with the man’s access to new sources of energy and the development of highly sophisticated technology, human element is assigned a more critical role in operating and controlling the systems. today in most work environments including nuclear, military and chemical industries a human error could result in a catastrophic even t. it is for this reason that the identification ...

BACKGROUND The electroencephalogram (EEG) reflects the electrical activity in the brain on the surface of scalp. A major challenge in this field is the localization of sources in the brain responsible for eliciting the EEG signal measured at the scalp. In order to estimate the location of these sources, one must correctly model the sources, i.e., dipoles, as well as the volume conductor in whic...

original article   introduction: human errors are of the most important issues due to the technological advances in various work settings. in medical professions, including nursing, investigation of human errors would help to find out approaches for the identification and reduction of these errors. hence, the present study aimed to identify and assess nurses' errors in emergency ward of an educ...

Ever since the introduction of coordinate measuring machines (CMMs), their measuring accuracy has been studied. Much research work has focused on the accuracy characteristics of the measuring system, e.g. the static errors and dynamic errors of the machines. However, the additional error sources can be introduced when a measuring coordinate system is set up. This paper describes how to analyse ...

The GPS (Global Positioning System) is used for navigation and positioning purposes by a diverse set of users. The navigation solution provided by a commercial GPS receiver is subject to errors contributed by various sources. These sources of errors in GPS navigation (e.g. satellite clock, receiver clock, atmospheric and multipath errors etc.) induce biases in the measurement of pseudo range an...

Among the major issues raised by classroom SLA researchers is the debate on the degree to which teacher’s or learner’s attention should be directed to linguistic features. However, one of the relevant variables in corrective feedback studies which seem to be less operationalized is the differential impact of different types of feedback on the accuracy of the oral performance of the participants...
