Universal mono-command support system for users with severe tetraplegia and anarthria
No full textThe paper describes two input devices and a software interface that allow severely impaired people to easily interact with a personal computer. The first input device does not require residual movement but makes use of skin electrical signals and applies Artificial Neural Networks to decode the mind-driven commands. The second input device is an evolution of a proximity sensor that can be activated using minimal residual movements, therefore it is suitable for the main part of motor disabilities. The software interface can be adapted to any kind of input device and makes it possible to access any standard software installed on a PC

Battery of Experiments and Signal Processing to Test the Existence of Quantum Properties at a Neural Level
No full textThe academic interest on the quantum mind framework was growing in the last decades, but experimental evidences are still lacking. This essay intends to represent a contribution and a trial in this direction. Building an experimental basis for the quantum mind framework means being on the right way to create a truly scientific - as falsifiable - body of theories. The book includes contributions of Rita Pizzi (University of Milan, Italy) and Wolfgang Baer (Nascent Systems,Inc, former Naval Postgraduate School, Monterey)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Affordable quantum cryptography system for mobile devices
No full textThe today’s technology allows us to design simple quantum cryptography circuits embeddable in mobile devices to ensure the maximum security in money transfer and controlled access. It is known that the quantum cryptography protocols allow a virtually perfectly secure key generation and exchange process. This technology uses the quantum property which states that orthogonally polarized states can be completely discriminated, thus can
be used to codify information.
The system presented in this paper adopts a properly costumized BB84 protocol. The hardware instrumentation
includes two fast PCs with acquisition card, a 4-channels transmitter, 4 high-efficiency LED diodes, a receiver with 4
highsensitivity photodiodes, and suitable optic devices.
Transmitter and receiver consist of two custom electronic cards with suitable software for random bit generation and
decoding procedures The software also allows to reconstruct the shared secure key. The system has been realized with the purpose to be included in mobile devices and to allow each one to afford the quantum cryptography security level, both for ATM operations and e-commerce transactions
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
