Abstract
We describe different scenarios where a learning mechanism is capable of acquiring experience on a source task, and subsequently exploit such experience on a target task. The core ideas behind this ability to transfer knowledge from one task to another have been studied in the machine learning literature under different titles and perspectives. Here we describe some of them under the names of inductive transfer, transfer learning, multitask learning, meta-searching, meta-generalization, and domain adaptation. © Springer Science+Business Media New York 2011, 2017

Abstract
Currently Information and Communication Technologies (ICT) support most of the industrial manufacturing processes. The IT revolution has brought an important transformation in organizations with high impacts, which are comparable to the mechanization and electricity brought in the first and second industrial revolution. This evolvement has promoted the emergence of cloud-based systems, the Internet of Things (IoT), Big Data, Industry 4.0, BYOD (Bring Your Own Device) and CYOD (Choose Your Own Device) trends. However, new technological solutions always carry security vulnerabilities, which most of time reveal unexpected risks. In fact, with increasing reliance on technology to gain competitive advantage, security issues have been one of the most critical and challenging requirements for conducting successful business. In this paper, it is highlighted some reflections regarding the challenges of Industry 4.0 emphasizing the security issues, towards raising awareness for security good practices within Industry 4.0.

Abstract
GRAVITY is a new instrument to coherently combine the light of the European Southern Observatory Very Large Telescope Interferometer to form a telescope with an equivalent 130m diameter angular resolution and a collecting area of 200 m(2). The instrument comprises fiber fed integrated optics beam combination, high resolution spectroscopy, built-in beam analysis and control, near-infrared wavefront sensing, phase-tracking, dual-beam operation, and laser metrology. GRAVITY opens up to optical/infrared interferometry the techniques of phase referenced imaging and narrow angle astrometry, in many aspects following the concepts of radio interferometry. This article gives an overview of GRAVITY and reports on the performance and the first astronomical observations during commissioning in 2015/16. We demonstrate phase-tracking on stars as faint as m(K) approximate to 10 mag, phase-referenced interferometry of objects fainter than m(K) approximate to 15 mag with a limiting magnitude of m(K) approximate to 17 mag, minute long coherent integrations, a visibility accuracy of better than 0.25%, and spectro-differential phase and closure phase accuracy better than 0.5 degrees, corresponding to a differential astrometric precision of better than ten microarcseconds (as). The dual-beam astrometry, measuring the phase difference of two objects with laser metrology, is still under commissioning. First observations show residuals as low as 50 mu as when following objects over several months. We illustrate the instrument performance with the observations of archetypical objects for the different instrument modes. Examples include the Galactic center supermassive black hole and its fast orbiting star S2 for phase referenced dual-beam observations and infrared wavefront sensing, the high mass X-ray binary BP Cru and the active galactic nucleus of PDS 456 for a few mu as spectro-differential astrometry, the T Tauri star S CrA for a spectro-differential visibility analysis, xi Tel and 24 Cap for high accuracy visibility observations, and eta Car for interferometric imaging with GRAVITY.

Abstract
The ageing process is naturally accompanied by changes in people's cognitive processes. The European population ageing is a challenge for the European social policy and for the mental health professionals. New technologies can play an important role in the neurocognitive stimulation area as they possess characteristics that might reduce the anxiety levels of patients participating in neurocognitive stimulation or assessment programs. In particular, serious games provide a setting that can be explored to improve the easy access to neurocognitive stimulation and assessment, regardless of place and time, at a lower cost then traditional approaches. This paper presents a serious game aiming to analyse neurocognitive deficits and stimulate the players' deficitary neurocognitive processes. This game is built on top of sound neurocognitive psychotherapy for adults, mainly addressing the cognitive processes of attention and memory. The game will simulate real world scenarios, allowing a better generalization process due to ecological validity.
