Bits, Mass and Acceleration Issued in BSC
No full textThe goal of the present paper is to expand already published works in the frame of “Banded speed cosmology” (BSC). In particular this paper gives validated values for physical quantities not so far investigated in previous publications, i.e., the number of individual physical entity in the universe, as well as the maximum value for acceleration. Validates values mean identical quantities from a numerical point of view obtained with different theoretical procedures, additionally compared with data based on NASA observations with Planck probe
New strength to Plank's length choice
Full text linkThe calculation of the total mass of a spacetime in which an observer-independent scale of length exist is possible through the use of Heisenberg Uncertainity Principle. In the following paragraphs we show that such a spacetime has a total mass equal to the mass of our Universe observed by the WMAP Nasa spacecraft if the cited observer-independent scale of length is determined by the Planck’s length lp.
This result gives new strength to fundamental theories that make use of lp as a length with a “special role”, like the various string theories
Band structure: a solid-state physics model with cosmological implications
No full textThis work is aimed at showing that the “band structure” of the energy distribution in solids which is a well-known model for electronic engineers and solid-state physics scientists is an efficacious description also for phenomena not tied to energy neither related to microcosm. In particular, it is displayed that how the elements of the consolidated physical theories, arranged together using the “band structure”, lead to a model for the distribution of speed in the universe that is essentially analogous to the distribution of energy in solids. The description is accompanied by references to the experimental data that sustain it, together with an overview of the possible development opportunities
An elegant Universe is a necessity, not just a case
No full textWe believe that well-known principles and relationships between physical entities are the key for a deep knowledge of reality. However, they must be applied using innovative points of view, points of view that can be provided by, for example, experts on information theory (as we are). Our previous efforts in this direction led to a fascinating result: the theoretical total mass of a spacetime in which Planck’s length is an observer-independent scale of length is equal (both in expression and value) to the mass of our portion of Universe measured by NASA WMAP spacecraft [1].
In the following paragraphs we’ll show how granularity (i.e. discontinuity) of physical entities of our portion of observable spacetime descends directly from the principles of information theory, and how a physical theory about the discontinuity of reality built on these basis can lead to an elegant descriptions of both microcosm and macrocosm
Improved location of trains involved in safety critical scenarios.
No full textIn the present paper we develop one proposal in our overview about satellite positioning in railways published some months ago on ERR [1], improving Railway Emergency Call (REC) functionality through the use of the future Galileo satellite positioning system. In particular we propose a high-level system architecture capable of transmitting very accurate train position information while producing REC towards Trackside Manager (TM)
Dark matter and other phenomena in the framework of banded speed cosmology
No full textThe descriptive capabilities of the banded speed cosmological model are shown. In particular, an in-depth analysis related to the actual physical meaning of Planck’s unit is given in the framework of the banded distribution of physical quantities. From this analysis the richness and flexibility of the model’s description capabilities is derived, with particular attention devoted to the ability of using the same relationships for describing both microcosm and macrocosm and also young and old universe. Finally the cited descriptive capabilities are used for deriving a very simple and intuitive explanation of the “darkness” of dark matter
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
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
