 | Army Installations often expand their use of digital control systems for heating, ventilating, and air conditioning and other mechanical and electrical building systems on a building-by-building basis. The control systems are installed under separate contracts by different contractors resulting in intra-system incompatibilities. The implementation of multi-vendor Open Building Automation Systems (BASs) is meant to overcome such incompatibilities; however BASs can present their own technical and administrative (including contractual) challenges. This ... |

| Quality attribute requirements are a driving force for software and system architecture design. Architectural patterns can be used to achieve quality attribute requirements. Consequently, architectural patterns generate value based on the present and future utility of the quality attributes they achieve. This report makes the case that architectural patterns carry economic value, in part in the form of real options, providing software architects the right, but not the obligation, to ... |

We discuss a weaker requirement called incident-insensitive noninterference that captures why these systems maintain the privacy of its users while possibly not satisfying noninterference. We extend this requirement to depend on dynamic information in a novel way. Lastly, we present a method based on ... |

| Abstraction reduces the problem of whether an infinite state system satisfies a temporal logic property to model checking that property on a finite state abstract version. The most common abstractions are quotients of the original system. We present a simple method of defining quotient abstractions by means of equations collapsing the set of states. Our method yields the minimal quotient system together with a set of proof obligations that guarantee ... |

| In this paper we present the different notions surrounding the concept called semantics enrichment which may significantly contribute facilitating the fusion process. After having introduced the role of the semantics in any command aid support, we show how it is possible to increase the relevance of operational information from its semantics. We propose a way to enrich semantics, firstly by making symbolic fusion, secondly by determining compatibility relations between pre-defined ... |

| Authors:
Stephen D. Howard; A. R. Calderbank; William Moran; PRINCETON UNIV NJ PROGRAM IN APPLIED AND COMPUTATIONAL MATHEMATICS
|
| This paper describes a new radar primitive that enables instantaneous radar polarimetry at essentially no increase in signal processing complexity. This primitive coordinates transmission of distinct waveforms on orthogonal polarizations and applies a unitary matched filter bank on receive. This avoids the information loss inherent in single-channel matched filters. A further advantage of this scheme is the elimination of range sidelobes. |
