Kistemaker, J.A. (author), den Hartog, E.A. (author), Daanen, H.A.M. (author), TNO Defensie en Veiligheid (author)The SensorTouch thermometer performs an infrared measurement of the skin temperature above the Superficial Temporal Artery (STA). This study evaluates the validity and the accuracy of the SensorTouch thermometer. Two experiments were performed in which the body temperature was measured with a rectal sensor, with an oesophageal sensor and with...article 2006

Kerstholt, J.H. (author), Passenier, P.O. (author)Automation has changed the role of human operators from direct manual control to supervision. Their main task is to monitor whether system performance remains within pre-specified ranges and intervention is only required in unusual situations. One of the consequences is a loss of situation awareness, which significantly affects performance in...article 2000

Schaafstal, A.M. (author)A theoretical framework for diagnosis in technical environments is presented, consisting of three layers. At the first layer, the task structure, top-level goals of the diagnostic tasks are identified that have to be fulfilled during task execution. This task structure may also be viewed as a global strategy to carry out the diagnostic task. The...article 1993
