REVERSE ELECTRODIALYSIS FOR POWER PRODUCTION FROM OILFIELD WASTEWATERS
2022
Produced waters (PWs) are wastewaters generated by crude-oil extraction processes. They can present very different characteristics depending on the field location and production process. Dispersed oil, dissolved organics and solid particles are usually the main components. Moreover, PWs can contain a very high quantity of dissolved salts 1, with a total dissolved solid (TDS) concentration up to 300 g/L. Each barrel of extracted oil requires the simultaneous extraction of 3 barrels of produced water2 on average. PWs are often discharged into the sea, or sent in evaporation ponds thus leading to a dramatic environment impact3. Reinjection in the extraction well is currently the most common an…
Evaluation of the wave energy density on the Sicilian coast
2016
In this article the wave energy density of the northern Sicilian coasts is evaluated and is used to evaluate the producibility of a wave nergy converter to be installed in an area in the north west part of Sicily. In particular, the objective of the study is the evaluation of a potential installation in an area between Trapani and Palermo, which are the largest cities in the north west part of Sicily. In particular in this research, the wave energy density of Sicily has been analyzed by using an analysis of wave data carried out in a 10-year period, using the measurements of buoyant of National Wave measuring System (RON - Rete Ondametrica Nazionale). The analysis shows that the north-weste…
Estimation of wind velocity over a complex terrain using the Generalized Mapping Regressor
2010
Abstract Wind energy evaluation is an important goal in the conversion of energy systems to more environmentally friendly solutions. In this paper, we present a novel approach to wind speed spatial estimation on the isle of Sicily (Italy): an incremental self-organizing neural network (Generalized Mapping Regressor – GMR) is coupled with exploratory data analysis techniques in order to obtain a map of the spatial distribution of the average wind speed over the entire region. First, the topographic surface of the island was modelled using two different neural techniques and by exploiting the information extracted from a digital elevation model of the region. Then, GMR was used for automatic …
Resource Allocation and Computation Offloading for Wireless Powered Mobile Edge Computing
2022
In this paper, we investigate a resource allocation and computation offloading problem in a heterogeneous mobile edge computing (MEC) system. In the considered system, a wireless power transfer (WPT) base station (BS) with an MEC sever is able to deliver wireless energy to the mobile devices (MDs), and the MDs can utilize the harvested energy for local computing or task offloading to the WPT BS or a Macro BS (MBS) with a stronger computing server. In particular, we consider that the WPT BS can utilize full- or half-duplex wireless energy transmission mode to empower the MDs. The aim of this work focuses on optimizing the offloading decision, full/half-duplex energy harvesting mode and energ…
Wola mocy w architekturze. Inspiracje Nietzscheańskie
2021
Po przedstawieniu swej interpretacji greckiej tragedii, w której współdziałają apollińskość i dionizyjskość, Nietzsche koncypował całościową teorię sztuki, w której zasadniczą rolę odgrywa wola mocy. Coraz bardziej pociągała go też idea architektury jako sztuki tworzonej z woli mocy i obejmującej najwyższe dążenia człowieka. Można przyjąć, że w przestrzeni architektonicznej apollińskość jest pięknem, a dionizyjskość jest wzniosłością. Oba żywioły dialektycznie syntetyzują się w postaci woli mocy będącej najpotężniejszą formą żywiołowości. Właśnie ona powołuje do życia wielką sztukę, która wspiera człowieka w jego przeobrażaniu się w nadczłowieka. Aby ta przemiana ontologiczna doszła do skut…
"Demokracja jacksonowska" a zmiana postawy legitymizacji władzy sądowniczej w USA
2021
The article discusses the issue of changes of the bases of legitimization for the state judiciary in the US during the so-called “Jacksonian Democracy”, i.e., the period from 1829 (the beginning of the presidency of Andrew Jackson) until the outbreak of the Civil War. During this period on the wave of the democratization process of public institutions in the US, popular elections were introduced to select judges at the state level. The reason for the introduced institution was the willingness of legal environments to make judges independent from the world of politics, as well as strengthening their social authority and a political position in a political system. The result of popular electi…

L’estètica emocional de la transformació: una revisitació barroca de la Faula d’Apol·lo i Dafne
2021
The well-known Sonnet XIII by Garcilaso de la Vega «A Dafne ya los brazos le crecían» was to establish the disconsolate figure of Apollo, pining for the loss of Daphne, as the literary paradigm of the pangs of love —at least in Renaissance literature in the Iberian peninsula. Thus, a century later, Francesc Fontanella revisited the Garcilaso sonnet and carried out a profoundly Baroque re-reading. The Catalan text ‘transforms’ the symmetry and order in which the Spanish sonnet describes the metamorphosis of the nymph into an inseparable amalgam between the old way of being and the new reality, between the human and the plant, and freezes the figure in mutation: neither the original form nor …
Iacobi Menochii iurisconsulti Papiensis divini atque humani iuris scientia peritissimi
Juridical work about the arbitrariness and power of judges, especially in the most difficult legal questions, for which there are no certain rules.
