An energy analysis of IEEE 802.15.6 scheduled access modes
2010
Body Area Networks (BANs) are an emerging area of wireless personal communications. The IEEE 802.15.6 working group aims to develop a communications standard optimised for low power devices operating on, in or around the human body. IEEE 802.15.6 specifically targets low power medical application areas. The IEEE 802.15.6 draft defines two main channel access modes; contention based and contention free. This paper examines the energy lifetime performance of contention free access and in particular of periodic scheduled allocations. This paper presents an overview of the IEEE 802.15.6 and an analytical model for estimating the device lifetime. The analysis determines the maximum device lifeti…
Electron structure, ultra-dense hydrogen and low energy nuclear reactions
2019
In this paper, a simple Zitterbewegung electron model, proposed in a previous work, is presented from a different perspective based on the principle of mass- frequency equivalence. A geometric- electromagnetic interpretation of mass, relativistic mass, De Broglie wavelength, Proca, Klein- Gordon, Dirac and Aharonov- Bohm equations in agreement with the model is proposed. A non-relativistic, Zitterbewegung interpretation of the 3.7 keV deep hydrogen level found by J. Naudts is presented. According to this perspective, ultra-dense hydrogen can be conceived as a coherent chain of bosonic electrons with protons or deuterons located in the center of their Zitterbewegung orbits. This approach sug…
The Judge in the Seventeenth century: a royal official between legislation, doctrine and case law: the Sicilian case
2013
Like all the others territorial-political systems in Europe, even Siciliy is characterized by the presence of royal Courts of Appeal, institutions that a consolidated – even if outdated – legal-historical tradition brought together under the generic name of “Grandi Corti” (Great Courts) or “Tribunali Supremi “ (Supreme Courts). It is known that the definition of “Grande Tribunale” can be related to the Suprem Court of every state-organization of the Modern Age; a high court composed only by the choicest jurists, personally appointed by the sovereign, with exclusive competence on a number of subjects (above all crimen lesae maiestatis) and competence of appeal on any sentence emitted by lowe…
The agency of non-human entity in the recent anthropology of the Indigenous Lowland South America
2015
In the last twenty years, agency has entered the field of anthropological studies of Lowland South America Indigenous Peoples as a term and a topic of concern. Ethnographical and theoretical treatment of this notion has intertwined here with the revisiting of the concept of animism, Viveiros de Castro’s statements about “amerindian perspectivism” and a broader “ontological turn” in research orientation. In the paper I discuss this trend, focusing on how different notions of agency are used to talk about topics as shamanism and ontological status of artifacts as well as, more generally, of other non-human categories of beings. I pay attention too to dissonances and consonances in this field …
The place of livestock in human-nonhuman relationship among the Wayuu
2020
In the ethnology of indigenous LSA, the Wayuu case has always been considered a peculiar one. Among the main features which make difficult to insert it in the comparative debate on indigenous models of sociality and cosmology in this area, one can mention: pristine introduction of cattle raising; maintenance of political semi-autonomy till very recent times; development, already in the colonial period, of forms of social hierarchy based on ownership of livestock and other material goods; articulation of these forms with a system of matrilineal descent groups; interplay among the inclusive character of the descendants of mixed unions and the shifting of the traits selected for marking ethnic…

Iterated Conditionals, Trivalent Logics, and Conditional Random Quantities
2022
We consider some notions of iterated conditionals by checking the validity of some desirable basic logical and probabilistic properties, which are valid for simple conditionals. We consider de Finetti’s notion of conditional as a three-valued object and as a conditional random quantity in the betting framework. We recall the notions of conjunction and disjunction among conditionals in selected trivalent logics. Then, we analyze the two notions of iterated conditional introduced by Calabrese and de Finetti, respectively. We show that the compound probability theorem and other basic properties are not preserved by these objects, by also computing some probability propagation rules. Then, for …
Quasi conjunction and p-entailment in nonmonotonic reasoning
2010
We study, in the setting of coherence, the extension of a probability assessment defined on n conditional events to their quasi conjunction. We consider, in particular, two special cases of logical dependencies; moreover, we examine the relationship between the notion of p-entailment of Adams and the inclusion relation of Goodman and Nguyen. We also study the probabilistic semantics of the QAND rule of Dubois and Prade; then, we give a theoretical result on p-entailment.
