The model-companion of a class of structures
Journal of Symbolic Logic, 1972If Σ is the class of all fields and Σ* is the class of all algebraically closed fields, then it is well known that Σ* is characterized by the following properties:(i) Σ* is the class of models of some first order theory K*.(ii) If m1m2 are in Σ* and m1 ⊆ m2 then m1 ≺ m2 (m1 is an elementary substructure of m2, i.e.

Power Asymmetries in Companion Modelling Processes [PDF]
, 2013 As discussed in the previous chapter, ComMod processes, like most participatory processes, are implemented in social contexts characterized by power asymmetries and conflicts of interest between stakeholders involved at different organizational levels.

Companion context dependent topic modeling
2014 Seventh International Conference on Mobile Computing and Ubiquitous Networking (ICMU), 2014Contexts such as time, location and companion play an important role to determine topics of documents. We focus on companion context (friends, wife, husband etc.) as one of the most important contexts to determine topics. We propose companion context dependent topic model by the extension of basic graphical model: LDA (Latent Dirichlet allocation).

A counterexample in the theory of model companions
Journal of Symbolic Logic, 1975In [7] we proved that (I) if T is a countable ℵ0-categorical theory without finite models then T has a model companion; and several people have observed that (II) if T is a countable theory without finite models which is ℵ1-categorical and forcingcomplete for infinite forcing (i.e., T= TF) then T is model-complete.

Model companions of the quasivarieties of polygons
Siberian Mathematical Journal, 1998The author studies the existence problem for model companions of quasivarieties of polygons. Let \(\mathcal H\) be the class of polygons which possesses the amalgamation property and the congruence extension property. In the article under review, the existence of a model companion for \(\mathcal H\) is proven to be equivalent to each of the following ...

Using Classification Learning in Companion Modeling
2009Companion Modeling is a methodology used to facilitate adaptive management of renewable resources by their users. It is using role-playing games (RPG) and multiagent simulations to validate initial models representing the functioning of complex systems to be managed.

Modeling curiosity for virtual learning companions
International Joint Conference on Autonomous Agents and Multiagent Systems, 2014Curiosity is an emotional motivation that drives knowledge acquisition in learning context. Studies have shown that curiosity positively influences social learning and a peer learner's curiosity may elicit the curiosity of other learners. Hence, modeling curiosity in learning companions may improve human learners' learning experience in virtual ...

Model companion and model completion of theories of rings
Archive for Mathematical Logic, 2009The usual language for rings is augmented by, for each natural number \(k\), a \(k+1\)-ary relation symbol \(\text{rad}_k\), the intended interpretation of which is that \(\text{rad}_k(a, b_1, \dots, b_k)\) holds iff every maximal ideal which contains \(b_1,\dots, b_k\) also contains \(a\).

The companion dog as a unique translational model for aging
Seminars in Cell & Developmental Biology, 2017The dog is a unique species due to its wide variation among breeds in terms of size, morphology, behaviour and lifespan, coupled with a genetic structure that facilitates the dissection of the genetic architecture that controls these traits. Dogs and humans co-evolved and share recent evolutionary selection processes, such as adaptation to digest ...

Companion Modelling: Variant of Geoprospective Approach
L’Espace géographique, 2012À la croisée entre modèles spatiaux, scénarios spatialisés et concertation sur l’avenir d’un territoire, la géoprospective donne une importance variable à chacun de ces trois volets. L’article analyse comment la modélisation d’accompagnement fait de la géoprospective et sous quelle forme particulière.
