Impact of Boron doping to the tunneling magnetoresistance of Heusler alloy Co2FeAl
, 2022 Heusler alloys based magnetic tunnel junctions can potentially provide high magnetoresistance, small damping and fast switching. Here junctions with Co2FeAl as a ferromagnetic electrode are fabricated by room temperature sputtering on Si/SiO2 substrates.

A spatial model for social networks
, 2005 We study spatial embeddings of random graphs in which nodes are randomly distributed in geographical space. We let the edge probability between any two nodes to be dependent on the spatial distance between them and demonstrate that this model captures ...

Characterization of reward functions in networks with costs [PDF]
, 2010 In this paper we study network structures in which the possibilities for cooperation are restricted and can not be described by a cooperative game. The benefits of a group of players depend on how these players are internally connected.

Властивості аморфних сплавів систем Al–РЗМ–Ni та Al–РЗМ–Ni–Fe з нанокристалічною фазою [PDF]
, 2012 Досліджено вплив відпалу на фізико-хімічні властивості аморфних сплавів на основі алюмінію. Встановлено, що після відпалу при температурі першої стадії кристалізації формується рентгеноаморфна структура з невеликою об’ємною часткою невпорядкованої ...

Gaussian estimates for a heat equation on a network
, 2007 We consider a diffusion problem on a network on whose nodes we impose Dirichlet and generalized, non-local Kirchhoff-type conditions. We prove well-posedness of the associated initial value problem, and we exploit the theory of sub-Markovian and ...

A case study of Consistent Vehicle Routing Problem with Time Windows
, 2020 We develop a heuristic for the Consistent Vehicle Routing Problem with Time Windows (ConVRPTW), which is motivated by a real-world application at a food company's distribution center.

The effects of imitation dynamics on vaccination behaviours in SIR-network model
, 2019 We present a series of SIR-network models, extended with a game-theoretic treatment of imitation dynamics which result from regular population mobility across residential and work areas and the ensuing interactions.

Evacuation modeling: a case study on linear and nonlinear network flow models
EURO Journal on Computational Optimization, 2016 We present a nonlinear traffic flow network model that is coupled to gaseous hazard information for evacuation planning. This model is evaluated numerically against a linear network flow model for different objective functions that are relevant for ...

Sink location to find optimal shelters in evacuation planning
EURO Journal on Computational Optimization, 2016 The sink location problem is a combination of network flow and location problems: from a given set of nodes in a flow network a minimum cost subset W has to be selected such that given supplies can be transported to the nodes in W.
