Game Theory Models for the Verification of the Collective Behaviour of Autonomous Cars
The collective of autonomous cars is expected to generate almost optimal
traffic. In this position paper we discuss the multi-agent models and the
verification results of the collective behaviour of autonomous cars. We argue
that non-cooperative autonomous adaptation cannot guarantee optimal behaviour.
The conjecture is that intention aware adaptation with a constraint on
simultaneous decision making has the potential to avoid unwanted behaviour. The
online routing game model is expected to be the basis to formally prove this
conjecture.Comment: In Proceedings FVAV 2017, arXiv:1709.0212
Validation of a magneto- and ferro-hydrodynamic model for non-isothermal flows in conjunction with Newtonian and non-Newtonian fluids
This work focuses on the validation of a magnetohydrodynamic (MHD) and ferrohydrodynamic
(FHD) model for non-isothermal flows in conjunction with Newtonian and non-
Newtonian fluids. The importance of this research field is to gain insight into the interaction of
non-linear viscous behaviour of blood flow in the presence of MHD and FHD effects, because
its biomedical application such as magneto resonance imaging (MRI) is in the centre of research
interest. For incompressible flows coupled with MHD and FHD models, the Lorentz force and
a Joule heating term appear due to the MHD effects and the magnetization and magnetocaloric
terms appear due to the FHD effects in the non-linear momentum and temperature equations,
respectively. Tzirtzilakis and Loukopoulos [1] investigated the effects of MHD and FHD for
incompressible non-isothermal flows in conjunction with Newtonian fluids in a small rectangular
channel. Their model excluded the non-linear viscous behaviour of blood flows considering
blood as a Newtonian biofluid. Tzirakis et al. [2, 3] modelled the effects of MHD and FHD for
incompressible isothermal flows in a circular duct and through a stenosis in conjunction with
both Newtonian and non-Newtonian fluids, although their approach neglects the non-isothermal
magnetocaloric FHD effects. Due to the fact that there is a lack of experimental data available
for non-isothermal and non-Newtonian blood flows in the presence of MHD and FHD effects,
therefore the objective of this study is to establish adequate validation test cases in order to assess
the reliability of the implemented non-isothermal and non-Newtonian MHD-FHD models.
The non-isothermal Hartmann flow has been chosen as a benchmark physical problem to study
velocity and temperature distributions for Newtonian fluids and non-Newtonian blood flows in
a planar microfluidic channel. In addition to this, the numerical behaviour of an incompressible
and non-isothermal non-Newtonian blood flow has been investigated from computational
aspects when a dipole-like rotational magnetic field generated by infinite conducting wires. The
numerical results are compared to available computational data taken from literature

Az abduktĂv menedzsmenttĹ‘l a tudáskormányzásig = From abductive management to knowledge governance
Hogyan juthat az ember helyes döntésekig egy adott területre (mikroverzumra) vonatkozó mély, belsővé
tett tudás birtokában anélkül, hogy következtetne? Az abduktivitás fogalmának körüljárása után öt hüvelykujjszabályt
fogalmaz meg a szerző az abdukció működéséről, majd összekapcsolja azt a vezetői munkával,
tudáskormányzási kontextusban. Ebből kiindulva a globális munkatérelmélet (Global Workspace
Theory) alkalmazásával a vezetĹ‘k vagy az organizmuskĂ©nt felfogott szervezetek abduktĂv kapacitásának
fejlesztési lehetőségeit vizsgálja. Befejezésül egy hatlépéses, a szervezeti szintű abduktivitásra rákérdező
speciális tudásaudit-módszertan rövid kifejtésére vállalkozik, két esettanulmány vázlatos bemutatásával. _____
How to make right decisions without any inferences, thanks to interiorized, deep knowledge on the given field (micro verse)? After defining the concept of abductivity, the author presents five thumbnail-like rules about the nature of abductivity, combining it with leadership aspects and knowledge governance approach. He introduces a method supporting the development of abductive capability of a leader or an organization as a whole, using the Global Works pace Theory. Finally, the author tries to briefly formulate six steps of an organization-level knowledge governance audit framework, illustrating its relevance with two short case studies
