A device itself has to be faced with many operation problems such as harsh operating environment and aging of components resulted from device's long time operation, possibly becoming contribute factors to hidden failures too.
In the last years more experience has been achieved with long time operation of solar tower receivers increased in size.
A high-Tc rf SQUID NDE system was developed for stable, long time operation in a noisy environment.
The backfire of gas fluidized bed furnaces often occurs with the premixing of air and gas after long time operation at high temperature is prevented completely.
Therefore, it is required to increase the elastic recovery for long time operation in extreme environments i.e. high temperature, radiation dose.
Among important issues are possible changes in the morphology and dispersion, as well as specific interactions leading to the improved chemisorptive and catalytic properties in addition to the feasibility of long time operation of the discussed systems.
The objective of the works described in the following was to minimise the water losses due to cracks and to guarantee the secure and durable long time operation of the cisterns consequently.
Under the long time operation, some uncontrollable factors will affect the Maglev train-at-ground structure vertical coupling vibration, including the supported stiffness change of subgrade, uneven settlement and the supported void.
In parallel, to ensure long time operation and to prevent undesirable performance degradation, a shutter system was also implemented in order to reduce impurity deposition on in-vessel mirrors but also to allow in situ transmission calibration.
Even though the evaluation can be done at various viewpoints, the evaluation viewpoints used in this paper are focused on accuracy of the 3D image by depth information, eyestrain for the long time operation, operation efficiency, reusability for captured information, and system configuration settings.
