Pre-service teachers’ conceptions of assessment have received relatively little attention in research concerned with professional development initial teacher education. These conceptions, alongside others regarding teaching and learning, however, a great impact on future instructional practices. In this study, the authors examine indirectly, by analysing 79 Finnish pre-service subject narrative...

The turbine blades play a crucial role in the efficiency of steam turbines system, which can also lead to safety and economic implications catastrophic failure. propagation fatigue cracks is relevant issue, especially if there are issues involving human life or environment significant losses. This work investigated failure blade 25 MW cogeneration power plant. One found several deformation mark...

Ensuring fast and accurate failure detection is a fundamental issue for building efficient fault-tolerant distributed systems. In an effort to make fault-tolerant applications easier to implement, we are trying to provide failure detection as a generic Internet service, similar to what was done very successfully with NTP (network time protocol) for clock synchronization. To do so, we must revis...
