Methods and tools for supporting industrial design innovation
The introduction of information technology (IT) systems to support designers’ activities and data management have profoundly affected company structure and design organization. This evolution has brought the introduction of systematic methods, close to information tools skills and prerogatives, using computer management and data recovery skills as main design support. The use of the IT also improved information exchange among different work figures involved during product development process.
In this direction authors have intended to analyze the role and the implementation of systematic methods and tools within industrial designer area of the design process and their impact on the conceptual design phase in particular. Consequently, the research has been developed primarily in reference to design methods able to support the strict ideation stage of the Conceptual Design, that can be referred to two typologies: knowledge based and functional approaches. Subsequently authors have analyzed the information tools currently used during design process, as CAD systems, and some innovative, as Virtual and Augmented Reality tools, that can be used within industrial design area.
The result of the study has been a formalization of the course followed during idea conceptual phase in order to include and to arrange the design methods and tools analysed. The research proposes a structured view of a process of product conceptualization, usually considered as mainly heuristic, focusing on the integration of methods and tools to support project and its communication. In this area the research has highlighted industrial designer role characteristics during design process, changeable in reference of project development level, and also some important new questions have been identified about the interaction between industrial designers and the other design areas involved in the process. In this direction the study has highlighted the need to support knowledge exchange and recovery, introducing the possibility to extend the research to the whole process and integrate industrial design and engineering collaboration in a more effective way.

MMM: May I Mine Your Mind?
Consider the following set-up for the plot of a possible future episode of
the TV series Black Mirror: human brains can be connected directly to the net
and MiningMind Inc. has developed a technology that merges a reward system with
a cryptojacking engine that uses the human brain to mine cryptocurrency (or to
carry out some other mining activity). Part of our brain will be committed to
cryptographic calculations (mining), leaving the remaining part untouched for
everyday operations, i.e., for our brain's normal daily activity. In this short
paper, we briefly argue why this set-up might not be so far fetched after all,
and explore the impact that such a technology could have on our lives and our
society.Comment: 4 pages, 0 figure, Accepted at the "Re-Coding Black Mirror" workshop

Electromagnetic self-force in curved spacetime: New insights from the Janis-Newman algorithm
We present an original approach to compute the electromagnetic self-force
acting on a static charge in Kerr spacetime. Our approach is based on an
improved version of the Janis-Newman algorithm and extends its range of
applicability. It leads to a closed expression which generalizes the existing
one and, since it does not involve the electromagnetic potential, it simplifies
the calculation of the self-force.Comment: 4 pages. Minor corrections, added references. Version accepted by

Creation of magnetic spots at the neutron star surface
According to the partially screened gap scenario, an efficient
electron-positron pair creation, a general precondition of radio-pulsar
activity, relies on the existence of magnetic spots, i.e., local concentrations
of strong and small scale magnetic field structures at the surface of neutron
stars. They have a strong impact on the surface temperature, which is
potentially observable. Here we reinforce the idea that such magnetic spots can
be formed by extracting magnetic energy from the toroidal field that resides in
deep crustal layers, via Hall drift. We study and discuss the magneto-thermal
evolution of qualitatively different neutron star models and initial magnetic
field configurations that lead to the creation of magnetic spots. We find that
magnetic spots can be created on a timescale of years with magnetic
field strengths G, provided almost the whole magnetic
energy is stored in its toroidal component, and that the conductivity in the
inner crust is not too large. The lifetime of the magnetic spots is at least
one million of years, being longer if the initial field permeates both
core and crust.Comment: Accepted by M.N.R.A.
Smart Humans... WannaDie?
It won't be long until our prostheses, ECG personal monitors, subcutaneous
insulin infusors, glasses, etc. become devices of the Internet of Things (IoT),
always connected for monitoring, maintenance, charging and tracking. This will
be the dawn of the Smart Human, not just a user of the IoT but a Thing in the
Internet. How long would it then take for hackers to attack us like they have
been attacking IoT devices? What would happen if hackers were able to blackmail
us threatening our IoT body parts? Smart Humans may become victims of the
devastating attack of WannaDie, a new ransomware that could provide the
plot-line for a possible future episode of the Black Mirror TV series.Comment: 5 pages, 3 figures, Accepted at the "Re-Coding Black Mirror" workshop

CCOs and the hidden magnetic field scenario
CCOs are X-ray sources lying close the center of supernova remnants, with
inferred values of the surface magnetic fields significantly lower (less than
about 1e11 G) than those of standard pulsars. In this paper, we revise the
hidden magnetic field scenario, presenting the first 2D simulations of the
submergence and reemergence of the magnetic field in the crust of a neutron
star. A post-supernova accretion stage of about 1e-4-1e-3 solar masses over a
vast region of the surface is required to bury the magnetic field into the
inner crust. When accretion stops, the field reemerges on a typical timescale
of 1-100 kyr, depending on the submergence conditions. After this stage, the
surface magnetic field is restored close to its birth values. A possible
observable consequence of the hidden magnetic field is the anisotropy of the
surface temperature distribution, in agreement with observations of several of
these sources. We conclude that the hidden magnetic field model is viable as
alternative to the anti-magnetar scenario, and it could provide the missing
link between CCOs and the other classes of isolated neutron stars.Comment: 7 pages, 7 figures, MNRA
