This note contains some material promised in our earlier papers on submodel preservation and the guarded fragment, along with some information on the current status of the problems mentioned in these papers ...
For further background to this example, Section 2 surveys a number of results concerning the submodel preservation property for various fragments of first-order logic. ...
Does equality-free two-variable first-order logic have the submodel preservation property? Next, we consider some other types of fragments of first-order logic. ...

A new submodelling technique for multi-scale finite element computation of electromagnetic fields: Application in bioelectromagnetism
2010
Journal of Physics, Conference Series
This is caused by the fact, that considered effects on smaller scales have greater influences on the whole model and larger scales. ...
New submodelling routine has been developed to sufficiently decrease the time of computation without loss of accuracy for the whole solution. ...
The thickness of the neuronal path is 0.5mm, which is not realistic in order to test the effect of CSR on the solution. ...

Events on an event list are held in ascending time (or timestamp) order and we say that a simu- lation is correct if these events have been processed in the right order. ...
When a submodel deter- mines that an entity representing orders or blood is to be
‘sent’ to another submodel, a timestamped event message is
sent to that submodel. ...

The relevance in LIMIDs is formalized by the notion of the partial evaluation of the maximum expected utility, and the graph separation criteria for identifying submodels follow. ...

Rich Models for Steganalysis of Digital Images
2012
IEEE Transactions on Information Forensics and Security
We demonstrate the proposed framework on three steganographic algorithms designed to hide messages in images represented in the spatial domain: HUGO, edgeadaptive algorithm by Luo et al. [32] , and optimallycoded ...
By observing the differences between how different submodels engage in detection, an interesting interplay between the embedding and detection is revealed. ...
Based on sample experiments with different algorithms and submodels, we determined that the best performance of each submodel is always achieved when q ∈ [c, 2c], where c is the residual order. ...

Urban Land Allocation Model of Territorial Expansion by Urban Planners and Housing Developers

The prototype consists of three submodels (one for each agent) that have been developed independently and present the same structure. ...
However, the first two are based on a land use allocation technique, and the last one, as well as their integration, on an agent-based model approach. ...

We generalize the submodel of nonlinear CP^1 models. The generalized models include higher order derivatives. ...
For the systems of higher order equations, we construct a B\"acklund-like transformation of solutions and an infinite number of conserved currents by using the Bell polynomials. ...

An engineering method for constraint based fracture assessment of welded structural components with surface cracks

Engineering Fracture Mechanics
It was found that when ®rst order elements were used, the constraint was higher in 3D than in plane strain. For second order elements, however, the trend was the opposite. ...
For the investigated case, the toughness requirements could be relaxed signi®cantly based on the two parameter analysis compared to conventional fracture mechanics analyses. # ...

Thus, a simultaneous submodel corresponds uniquely to a set of vertices and their connecting arcs, such that there exists a directed sequence of arcs connecting every ordered pair of vertices (a start ...

Interpolating model identification for SISO linear parameter-varying systems

First, the poles and zeros of the local LTI models are interpolated by polynomials and afterwards, the interpolating LPV model is obtained as the series connection of low-order LPV submodels, constructed ...
The method is restricted to systems with one scheduling parameter and is based on the assumption that all states of the system can be measured. ...

State estimation for non-linear systems using a decoupled multiple model
2008
International journal of Modeling, identification and control
This latter structure is an interesting alternative to the popular Takagi-Sugeno multiple model because different orders of submodels can be considered. ...
In this modelling framework, a judicious combination of a set of submodels makes it possible to describe the behaviour of a non-linear system. ...
In the first case, the submodels use a common state vector; in the second one, the submodels have a different state vector. ...

How Useful are Historical Data for Forecasting the Long-Run Equity Return Distribution?
2007
Social Science Research Network
Our focus is on learning about breaks in real time and assessing their impact on out-of-sample density forecasts. ...
The shape of the long-run distribution and the dynamics of the higher-order moments are quite different from those generated by forecasts which cannot capture structural breaks. ...
In order to select informative priors based on features of excess returns, we conduct a prior predictive check on the submodel (Geweke (2005) ). ...
