This paper reviews progress that has been made over the last 50 years and discusses how the development and application of new technologies have been utilized to increase our understanding of the development and selection of the dominant follicle. Our increased knowledge from research carried out worldwide, has demonstrated that the development of the dominant follicle, and importantly the prod...

Considering the possibility of unexpected situations, the authorities feel the necessity of keeping certain sub systems or components of aircraft under continuous scrutiny. Accordingly, sensors in flight control systems are considered as one of the crucial components of the system. The failure to detect faults is quite likely to cause very serious problems, which makes it vital to carry out eff...

We present a new algorithm for generating a formal proof that an access request satisfies access-control policy, for use in logic-based access-control frameworks. Our algorithm is tailored to settingswhere credentials needed to complete a proof might need to be obtained from, or reactively createdby, distant components in a distributed system. In such contexts, our algorithm substan...
