The protection of information in computer systems
"... This tutorial paper explores the mechanics of protecting computer-stored information from unauthorized use or modification. It concentrates on those architectural structures--whether hardware or software--that are necessary to support information protection. The paper develops in three main sectio ..."

Loopy belief propagation for approximate inference: An empirical study. In:
- Proceedings of Uncertainty in AI,
, 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" -the use of Pearl's polytree algorithm in a Bayesian network with loops -can perform well in the context of error-correcting codes. The most dramatic instance of this is the near Shannon-limit performanc ..."

in a more gen eral setting? We compare the marginals com puted using loopy propagation to the exact ones in four Bayesian network architectures, including two real-world networks: ALARM and QMR. We find that the loopy beliefs of ten converge and when they do, they give a good approximation
Terabit burst switching
- J. of High Speed Networks
, 1999
"... This report summarizes the results of an architectural study on Terabit Burst Switching. The purpose of this study was to explore alternative architectures for very high performance switching for data communication, using a combination of optical and electronic technologies. We explore two alternati ..."

, it is feasible to construct systems with aggregate capacities of tens of terabits per second and that e ciently support highly dynamic data communication applications with individual channel rates of 10 Gb/s. The integrated architectures allow greater scalability and superior performance, but their viability
Tradespace Exploration for Space System Architectures: A Weighted Graph Framework
, 2014
"... Many systems undergo significant architecture-level change during their lifecycles as a result of exogenous system disturbances (e.g. budget reduction or changes in stake-holder requirements), failure to develop critical technologies, or planned evolution of the system over time. Given the high cost ..."

cost in terms of resources, schedule, and performance of making these changes during system development or operations, it is essential to make these decisions with a thorough understanding of the available options and costs associated with different architecture changes. The analysis of such decisions
Scenario planning in dynamic multi-attribute tradespace exploration
- In 3rd Annual IEEE International Systems Conference
, 2009
"... Abstract — The long time scales associated with complex system design and operation necessitate front-end systems engineering methodologies that enable consideration of alternative futures. This paper advances scenario planning techniques through a parameterization and ordering of potential future c ..."
