متن کاملSafety of Nuclear Ships
Economics and energy aspects of food irradiation were also discussed. Disinfestation of bulk grain, of bagged flour, preservation (radunzation) of packaged beef cuis and salmonella elimination from (radicidation of) poultry with electron accelerators, using electron beams or X-rays, were computed to be economically feasible and competitive. Deiailed analyses of the energy requirements of food p...
متن کاملWorking with alarms on ships ICT work on ships
Alarm indicators are a very simple and important user interface for many control tasks, and are known to be problematic. Alarms on ships have increased in number and importance. Recent incidents such as Savannah Express, Aquitaine and others have identified a number of important issues in the way that alarm systems support safe and effective work. The state of alarm systems onboard is inconsist...

Methods: In present study, posture and musculoskeletal condition of 207 individual of shi...
متن کاملIdentification of Dynamically Positioned Ships
Todays model-based dynamic positioning (DP) systems require that the ship and thruster dynamics are known with some accuracy in order to use linear quadratic optimal control theory. However, it is diicult to identify the mathematical model of a dynamically positioned (DP) ship since the ship is not persistently excited under DP. In addition the ship parameter estimation problem is nonlinear and...
