Four-level Architecture for Closure

by Nick Rossiter, Michael Heather - in Interoperability, EFIS2003, Fifth International Workshop on Engineering Federated Information Systems
"... Abstract. A definition of types in an information system is given from real-world abstractions through data constructs, schema and definitions to physical data values. Category theory suggests that four levels are sufficient to provide ultimate closure for computational types to construct informatio ..."

Next-generation synthetic gene networks.

by Timothy K Lu - Nat. Biotechnol. , 2009
"... Synthetic gene networks: what have we learned and what do we need? The engineering of mechanical, electrical and chemical systems is enabled by well-established frameworks for handling complexity, reliable means of probing and manipulating system states and the use of testing platforms-tools that a ..."

-characterized and interoperable modules (e.g., switches, oscillators and interfaces) that could be used in a plug-and-play fashion to create higher-order networks and programmable cells. As the number of parts and modules expands, high-throughput, combinatorial efforts for quantifying the levels of interference and cross

CONDITIONS FOR INTEROPERABILITY

by Nick Rossiter, Michael Heather
"... Abstract: Interoperability for information systems remains a challenge both at the semantic and organisa-tional levels. The original three-level architecture for local databases needs to be replaced by a categorical four-level one based on concepts, constructions, schema types and data together with ..."

Absence of Endochondral Ossification and Craniosynostosis in Posterior Frontal Cranial Sutures of Axin22/2 Mice

by Michael T. Longaker, Natalina Quarto
"... During the first month of life, the murine posterior-frontal suture (PF) of the cranial vault closes through endochondral ossification, while other sutures remain patent. These processes are tightly regulated by canonical Wnt signaling. Low levels of active canonical Wnt signaling enable endochondra ..."

investigated during the physiological time course of PF-suture closure and compared in detail with wild type littermates. Histological analysis revealed that the architecture in Axin22/2 PF-sutures was significantly altered in comparison to wild type. The distance between the endocranial layers

IEC 61375-1 and UIC 556- International Standards for Train Communication

by Christoph Schafers, Gernot Hans, Daimlerchrysler Rail, Systems Gmbh
"... Abstract- The communication system within a train is a central issue for train system integration. Historically, there have been numerous, proprietary and non-interoperable solutions. IEC 61375 and UIC 556 have now been issued as a set of international standards to overcome this situation: IEC 61 37 ..."
Abstract - Cited by 1 (0 self) - Add to MetaCart
375, the Train Communication Network (TCN), defines a communication architecture and the necessary protocols for non-vital communication on train and on vehicle level. It consists of a two-layered, hierarchical architecture to suit the needs of inter- and intra-vehicle communication. UIC 556

of Semantic Information Integration and the Context Mediation Approach

by Thomas Gannon, Marwan Sabbouh, Michael Siegel, Hongwei Zhu, Thomas Gannon, Mitre Corporation, Michael Siegel, Stuart Madnick, Marwan Sabbouh, Allen Moulton, Hongwei Zhu , 2009
"... Technological advances such as Service Oriented Architecture (SOA) have increased the feasibility and importance of effectively integrating information from an ever widening number of systems within and across enterprises. A key difficulty of achieving this goal comes from the pervasive heterogeneit ..."

The Anticipatory and Systemic Adjointness of E-Science Computation on the Grid, Computing Anticipatory Systems

by M. A. Heather, B. N. Rossiter - Proceedings CASYS‘01 , 2002
"... Abstract. Information systems are anticipatory systems providing knowledge of the real world. If e-science is to operate reactively across the Grid it needs to be integrable with other information systems and e-commerce. Theory suggests that four strong-anticipatory levels of computational types are ..."
