Based on general arguments presented in this report, nuclear criticality was eliminated from performance assessment calculations for the Waste Isolation Pilot Plant (WIPP), a repository for waste contaminated with transuranic (TRU) radioisotopes, located in southeastern New Mexico. At the WIPP, the probability of criticality within the repository is low because mechanisms to concentrate the fis...

HAOHAN LI: Scheduling Mixed-Criticality Real-Time Systems (Under the direction of Dr. Sanjoy K. Baruah) This dissertation addresses the following question to the design of scheduling policies and resource allocation mechanisms in contemporary embedded systems that are implemented on integrated computing platforms: in a multitasking system where it is hard to estimate a task’s worst-case executi...

Abstract Reliability and accessibility of distribution systems are important goals that have significant impacts on the costs. The proper strategy maintenance based components arrangement assets is best way to reach these goals. This a kind uses reliability-centered (RCM). Due limited budget, performing activities for all system neither possible nor logical. So most resources should be allocate...

We present a general conceptual framework for self-organized criticality (SOC), based on the recognition that it is nothing but the expression, "unfolded" m a suitable

The degree of operational sub-criticality of an Accelerator-driven System (ADS) on the one hand directly affects key accelerator system parameters, such as the proton beam current required to sustain the selected rated power level and, on the other, the likelihood of approaching or attaining criticality under abnormal or accident conditions. Then, if in all such conditions the safety goal is pu...
