State Estimation in Multi-Agent Decision and Control Systems [PDF]

open access: yes, 2005
his thesis addresses the problem of estimating the state in multi-agent decision and control systems. In particular, a novel approach to state estimation is developed that uses partial order theory in order to overcome some of the severe computational ...

Diagnosability Enforcement in Discrete Event Systems Using Labeled Petri Nets

open access: yesIEEE Access
This research solves the problem of diagnosability enforcement in discrete event systems modeled by labeled Petri nets. Since fault diagnosis relies on system observations, the detection of the occurrence of faults can be interfered with by deadlocks ...

Characterising Enterprise Application Integration Solutions as Discrete-Event Systems

open access: yes, 2015
It is not difficult to find an enterprise which has a software ecosystem composed of applications that were built using different technologies, data models, operating systems, and most often were not designed to exchange data and share functionalities ...

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

open access: yesAdvanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

open access: yesAdvanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Critical Observability Enforcement in Discrete Event Systems Using Differential Privacy

open access: yesMathematics
In the context of discrete event systems (DESs), critical states usually refer to a system configuration of interest, describing certain important system properties, e.g., fault diagnosability, state/language opacity, and state/event concealment ...
