Next Priority Concept: A new and generic algorithm computing concepts from complex and heterogeneous data [article]

Christophe Demko and Karell Bertet and Cyril Faucher and Jean-François Viaud and Sergeï Kuznetsov
2019 arXiv   pre-print
In this article, we present a new data type agnostic algorithm calculating a concept lattice from heterogeneous and complex data.  ...  Our NextPriorityConcept algorithm is first introduced and proved in the binary case as an extension of Bordat's algorithm with the notion of strategies to select only some predecessors of each concept,  ...  Acknowledgements: Thanks are owed to Rokia Missaoui and Gaël Lejeune for their constructive and helpfull comments.  ...

2003 Journal of Geophysical Research  
The FFM was designed to have two separate states-"test sequence" and "flight sequence" .  ...  Launch D etails Detailed use of all the auroral environment data mentioned above was involved in deter mining when to call for or hold the launch, as described below.  ...  where a is the radius of FFM, I is the moment of inertia of FFM and f is the friction force. When it satisfies v = wo, the FFM stops sliding and begins rolling without slipping.  ...

Dynamics and Observational Appearance of Circumstellar Disks [article]

Andrew F. Nelson
1999 arXiv   pre-print
I also study the detection limits available to radial velocity searches for low mass companions to main sequence stars.  ...  In my thesis I present a study of the dynamics and observational characteristics of massive circumstellar disks in two dimensions (r, ϕ) using two complimentary hydrodynamic codes: a 'Smoothed Particle  ...  We are grateful to several people for providing the radial velocity data used in this work.  ...
