Broadband mobile networks utilize a radio resource control (RRC) state machine to allocate scarce radio resources. Current implementations introduce high latencies and cross-layer degradation. Recently, the RRC enhancements, continuous packet connectivity (CPC) and the enhanced forward access channel (Enhanced FACH), have emerged in UMTS. We study the(More)
We present an approach to the integration of the quantitative and qualitative aspects of safety assessment to facilitate the certification of complex systems using a quantitative criteria. The approach is based on documenting all of all of the relevant safety factors in a system safety case and then transitioning all of the qualitative factors to(More)
Watersheds are of great ecological significance not only because they are important components of virtually all ecosystems but also because they are closely related to water quality, estuarine productivity, and wildlife habitat. In recent years, to enhance intensive watershed restorations, many watershed land cover characterization studies have been(More)

This thesis is an investigation into issues involving computers, information, and automation in the designing of large-scale environments. It is an attempt to understand the issues at root in developing an "intelligent" design environment which provides tools for handling tasks often too mundane and distracting for sustained design activity. In the process(More)
Unmanned Aircraft Systems (UASs) rely upon a significant amount of software. An appropriate authorizing agent must approve the use of the UAS in a desired environment before use, and the authorization approach used must contend with the UAS' software. Unfortunately, the variety of UAS types, the range of environments within which they must operate, and the(More)
