The causal differential scattering approach to calculating the effective properties of random composite materials with a particle size distribution [chapter]

A. Young, A. J. Mulholland, R. L. O'Leary
2009 Springer Proceedings in Physics  
An implementation of the Causal Differential Method (CDM) for modelling the effective properties of a random two-phase composite material is presented.  ...  The model predictions would suggest that to reliably and repeatedly manufacture these composites, with a desired mechanical impedance, a low volume fraction of inclusions should be used.  ...  Young, A. and Mulholland, A.J. and O'Leary, R.L. (2009) The causal differential scattering approach to calculating the effective properties of random composite materials with a particle size distribution  ...

A composite-likelihood approach for identifying polymorphisms that are potentially directly associated with disease

Joanna M Biernacka, Heather J Cordell
2008 European Journal of Human Genetics  
Here we propose a method that combines analyses of two or more candidate SNPs using a composite-likelihood approach.  ...  If a linkage signal can be fully accounted for by the association of a particular polymorphism with the disease, this polymorphism may be the sole causal variant in the region.  ...  Simulation study Using simulations, we compared the new composite-likelihood approach to the Li-cpg 7 approach.  ...

A Novel Framework for Integrating Discrete Event System Control and Diagnosis

Gregory M. Provan
2003 International Joint Conference on Artificial Intelligence  
A Discrete Event Modeling Framework We adopt a representation that is a hybrid of two key modeling approaches, an MBD approach, Causal Networks (CN) [Darwiche, 1998] , and an FSM control/diagnosis approach  ...  We assume that, to perform fault isolation, for the FSM (CN) approach we use a diagnoser (CN model respectively.  ...

Compositional Hierarchical Tensor Factorization: Representing Hierarchical Intrinsic and Extrinsic Causal Factors [article]

M. Alex O. Vasilescu, Eric Kim
2020 arXiv   pre-print
However, object appearance is the compositional consequence of both an object's intrinsic and extrinsic causal factors, where the extrinsic causal factors are related to illumination, and imaging conditions  ...  Therefore, this paper proposes a unified tensor model of wholes and parts, and introduces a compositional hierarchical tensor factorization that disentangles the hierarchical causal structure of object  ...  (b) Only one of the causal factor has a compositional hierarchical representation, a partially compositional hierarchical representation example.  ...

Sessional dataflow

Dominic Duggan, Jianhua Yao
2012 Proceedings of the 7th workshop on Declarative aspects and applications of multicore programming - DAMP '12  
This account focuses on a simplified case of sessional dataflow, to draw out the key points of the approach.  ...  The purpose of sessional dataflow is to provide a compositional semantics for dataflow computations that can be scheduled at compile-time.  ...  In general, the approach to composition of actors is to provide a binary connection operation for linking the output data channel on one actor with the input data channel of another.  ...

Non interleaving process algebra [chapter]

J. C. M. Baeten, J. A. Bergstra
1993 Lecture Notes in Computer Science  
We study the connection with Petri nets, and introduce causalities and a causal state operator.  ...  We study a non interleaving subalgebra of a reduct of a model of ACP. The model discussed uses step bisiroulation semantics.  ...  In Petri nets, the tokens provide a bookkeeping of causalities which is so expressive that both sequential composition and communication cease to be necessary primitives.  ...
