چکیده

Different graphical tools (Bond Graph, Signed diercted graph, Temporal Causal Garaph, ...) have been developed to perform diagnosis of chemical processes. As hypergraphs generalize graphs in which an edge can connect any number of vertices, this paper aims to generate a hypergraph model-based fault detection and isolation. The directed hypergraph model of chemical reaction kinetics have been used to generate redundancy relations. The proposed fault indicator scheme is illustrated through a reaction which has a secondorder reaction rate

On finding hypercycles in chemical reaction networks

Directed hypercycles have recently been used to model chemical reaction networks. We present an NP-completeness proof for the problem of finding a hypercycle in a directed hypergraph. This sheds some light to some open questions posed by Zeigarnik [A.V. Zeigarnik, On hypercycles and hypercircuits in hypergraphs, in: Discrete Mathematical Chemistry, in: DIMACS Series in, Discrete Mathematics and...

Directed domination in oriented hypergraphs

ErdH{o}s [On Sch"utte problem, Math. Gaz. 47 (1963)] proved that every tournament on $n$ vertices has a directed dominating set of at most $log (n+1)$ vertices, where $log$ is the logarithm to base $2$. He also showed that there is a tournament on $n$ vertices with no directed domination set of cardinality less than $log n - 2 log log n + 1$. This notion of directed domination number has been g...

Design of a Multi-model Observer-based Estimator for Fault Detection and Isolation (fdi) Strategy: Application to a Chemical Reactor

This study presents a FDI strategy for nonlinear dynamic systems. It shows a methodology of tackling the fault detection and isolation issue by combining a technique based on the residuals signal and a technique using the multiple Kalman filters. The usefulness of this combination is the on-line implementation of the set of models, which represents the normal mode and all dynamics of faults, if...

Mechanism-Based Studies of the Active Site-Directed Inhibition and Activation of Enzyme Transketolase

Derivatives of phenyl-keto butenoic acids have been reported to be inhibitors of pyruvate decarboxylase, (PDC). The inhibition of transketolase, a thiamine requiring enzyme such as PDF, by meta nitrophenyl derivative of 2-oxo-3-butenoic acid (MNPB) is reported here. These studies indicate that the inhibitor binds to the enzyme at the active site. A two-step inhibition was observed, first th...

Graphical Model Based for Robust Fault Diagnosis

In this paper, robust Fault Detection and Isolation (FDI) design in nonlinear uncertain dynamic system, with chemical and thermodynamic phenomenon, is addressed. The methodology using a Bond Graph (BG) representation in linear fractional transformation (LFT) form is shown to be a valuable tool for developing dynamic threshold generators and achieving robustness against model uncertainty in comb...
