MABS validation through repeated execution and data mining analysis
No full textAgent Based Modelling is the most interesting and advanced approach for simulating a complex system: in a social context, the single parts and the whole are often very hard to describe in detail. Besides, there are agent based formalisms which allow to study the emergency of social behaviour with the creation and study of models, known as artificial societies. Thanks to the ever increasing computational power, it's been possible to use such models to create software, based on intelligent agents, which aggregate behaviour is complex and difficult to predict, and can be used in open and distributed systems. Data mining is born in the last decades in order to help users in finding useful knowledge from the otherwise overwhelming amount of data available nowadays from the web and the data collected every day by companies. Data Mining techniques can therefore be the keystone to reveal non-trivial knowledge expressed by the initial assumption used to build the micro-level of the model and the structure of the society of agents that emerged from the simulation

Blocking Temperature Engineering in Exchange-Biased CoFeB/IrMn Bilayer
No full textIn this paper, we report on the magnetic and chemical characterization of the exchange-biased CoFeB/IrMn bilayers, grown
by magnetron sputtering on a Si-based platform and capped by either a Ru or MgO/Ru overlayer. For Ru capping, the locking temperature monotonously increases with the IrMn thickness within the investigated range (3.5–8 nm). On the contrary, for MgO/Ru capping, the exchange bias is inhibited below 6 nm, whereas above 6 nm, the magnetic behavior is the same of Ru-capped films. The chemical analysis reveals a significant dependence of the Mn content from the capping layer for thin IrMn films (2.5 nm), whereas the difference disappears when IrMn becomes thick (7 nm). Our work suggests that a non-uniform composition of the IrMn films directly affects the exchange coupling at the IrMn/CoFeB interface
Assessing The Impact Of Automatic Static Analysis On Software Quality
No full textAutomatic static analysis (ASA) tools analyze the source or compiled code of a software system looking for violations of recommended programming practices (called issues) that might either cause failures or degrade some dimensions of software quality. Dr. Antonio Vetrò, under the supervision of Prof. Dr. Maurizio Morisio and Prof. Dr. Marco Torchiano, has focused his doctoral research in studying how to improve software quality by applying ASA. He has taken the standard ISO/IEC 25010 as a reference model and has focused on four main areas: Functional suitability, Reliability, Performance and Maintainability (in terms of Technical Debt). The epistemological approach used is that one of empirical software engineering. Dr. Vetrò has also investigated new research directions for this field, i.e. using ASA for improving software energy efficiency and to detect problems derived from the interaction of different languages. The contribution is finally enriched with a generalized process for researchers and practitioners to improve software quality through ASA and create a body of knowledge on the topic based on empirical evidence. This book represents a first step towards these goal

Electric field control of magnetic properties and electron transport in BaTiO3-based multiferroic heterostructures
No full textIn this paper, we report on a purely electric mechanism for achieving the electric control of the interfacial spin polarization and magnetoresistance in multiferroic tunneling junctions. We investigate micrometric devices based on the Co/Fe/BaTiO3/La0.7Sr0.3MnO3 heterostructure, where Co/Fe and La0.7Sr0.3MnO3 are the magnetic electrodes and BaTiO3 acts both as a ferroelectric element and tunneling barrier. We show that, at 20 K, devices with a 2 nm thick BaTiO3 barrier present both tunneling electroresistance (TER = 12 ± 0.1%) and tunneling magnetoresistance (TMR). The latter depends on the direction of the BaTiO3 polarization, displaying a sizable change of the TMR from -0.32 ± 0.05% for the polarization pointing towards Fe, to -0.12 ± 0.05% for the opposite direction. This is consistent with the on-off switching of the Fe magnetization at the Fe/BaTiO3 interface, driven by the BaTiO3 polarization, we have previously demonstrated in x-ray magnetic circular dichroism experiments
