Addressing the Qualification Problem in FLUX
[chapter]
2001
Lecture Notes in Computer Science
We present a logic programming method to cope with the Qualification Problem in the action programming language Flux, which builds on the Fluent Calculus as a solution to the fundamental Frame Problem. ...
The Qualification Problem arises for planning agents in realworld environments, where unexpected circumstances may at any time prevent the successful performance of an action. ...
The accompanying concept of preferred extensions helps selecting the most reasonable explanations in case of unexpected action. 3 Addressing the Qualification Problem in FLUX
Basic FLUX Our system is ...

WSSL: A Fluent Calculus-Based Language for Web Service Specifications
[chapter]
2013
Lecture Notes in Computer Science
These issues involve the frame, ramification and qualification problems, which deal with the succinct and flexible representation of non-effects, indirect effects and preconditions, respectively. ...
We propose WSSL, a novel specification language for services, based on the fluent calculus, that is expressly designed to address the aforementioned issues. ...
This research was partially funded by the PaaSage (FP7-317715) EU project, as well as the Special Account for Research Grants, University of Crete (Grant No. 3742). ...

On the uniqueness of solution of magnetostatic vector‐potential problems by three‐dimensional finite‐element methods
1982
Journal of Applied Physics
It is also shown that the flux density is unique without qualifications. The theoretical and numerical uniqueness of the magnetic vector potential in three-dimensional problems is also given. ...
In this paper, particular attention is paid to the impact of finite-element approximation on uniqueness and to approximations implicit in finite element formulations from the uniqueness requirements standpoint ...
It has been shown that the flux density solution is unique with no qualifications. ...

Qualification and validity of a smeared fractures modeling approach for flow and transport in fractured media
[chapter]
2002
Developments in Water Science
Modeling flow and transport in a natural fractured medium is a difficult issue due among others to the large contrasts in the medium, its geometrical complexity as well as the strong level of uncertainties ...
The limits of the approach for large cinetical contrasts throughout the domain will be further studied in the future. ...
The total flux through the system as well as the local flux in the major conductors typically differ by one percent. ...

Development and qualification of a smeared fracture modelling approach for transfers in fractured media
[chapter]
2007
Groundwater in Fractured Rocks
The development and qualification of a novel smeared fracture approach adapted to these conditions is presented. ...
Flow and transport are solved using a Mixed Hybrid Finite Element method, limited here to 2D problems for the sake of simplicity. ...
Qualification strategy The smeared fracture procedure allows for a priori exact computation of water and mass fluxes in single fractures, but the approach has to be qualified for reference calculations ...

As the net churns: Fast-flux botnet observations
2008
2008 3rd International Conference on Malicious and Unwanted Software (MALWARE)
To address this gap in understanding, we have been mining live traffic to discover new fast-flux domains and then tracking those botnets with active measurements for several months. ...
We found that the active lifetimes of fast-flux botnets vary from less than one day to months, domains that are used in fast-flux operations are often registered but dormant for months prior to activation ...
Acknowledgments The authors would like to thank Robert Danford for his discussion with the authors while developing the screening heuristics, and the ATLAS engineering team for improvements in the fast-flux ...
