Towards an integrated design of renewable electricity generation and storage systems for NZEB use: A parametric analysis
2021
Abstract Although nearly zero energy buildings have attracted growing research attention, literature analysis shows that only a limited number of researches try to couple load match/grid interaction issues and environmental impacts in early design stages. The study proposes a novel multidisciplinary design approach that allows to integrate these two conflicting aspects aiming to find trade-offs. The proposed approach has been applied to a building case study, equipped with a photovoltaics system without energy storage. The results show that even though on yearly basis the energy use (5,290 kWhe) is largely overcome by the on-site energy generation (8069 kWhe), an oversized PV system alone m…
Coupling electrodialysis desalination with photovoltaic and wind energy systems for energy storage: Dynamic simulations and control strategy
2020
Abstract The presence of desalination systems in polygeneration facilities is usually limited by important difficulties in operating under non-stationary regimes typical of renewable energy sources. Reverse osmosis, namely the most common desalination technology, is characterised by slow dynamics that rarely adapts to the power fluctuations of renewables. Therefore, the possibility of using electrodialysis coupled with a hybrid photovoltaic/wind energy source was investigated in this work. In particular, the combination of photovoltaic and wind energy is very attractive in order to achieve a more stable energy production, while electrodialysis is claimed to be a more flexible process compar…
The adoption of photovoltaic micro production systems in Finland
2016
A sustainable supply of energy is one of the most important requirements in order to achieve sustainable development. By using renewable resources society is not dependent on depleting reserves, but instead can have an inexhaustible source of clean energy. The rapid development of photovoltaics has led to lowered prices and increased efficiency making them more attractive alternative as a source of household electricity. Although governments play a key role in setting the constraints of how renewable energy is adopted, the wide-spread adoption of distributed electricity production ultimately depends on consumer decisions to buy them. This study examined the adoption process of photovoltaic …
Note: Direct sensor resistance-to-frequency conversion with generalized impedance converter.
2010
In this note a squared output signal is generated from an astable circuit. Its frequency has a linear dependence on the resistance value of a resistive temperature sensor. The main circuit to obtain this direct relationship is the generalized impedance converter configured as a capacitor controlled by a sensor resistance. The proposed measurement method allows a direct analog-to-digital interface of information involved in resistive sensors. The converter finds applications in portable low voltage and low power design of instrumentation electronic systems.
Online pricing for demand-side management in a low-voltage resistive micro-grid via a Stackelberg game with incentive strategies
2022
It has been demonstrated that online pricing mechanisms are a viable solution for demand side management in power systems. This study deals with the analysis and design of a droop-controlled low-voltage resistive AC micro-grid network system. Such a system is subjected to a dynamic demand obtained from an online pricing mechanism, which is proposed as a novelty in the study of micro-grids. This mechanism is derived from a variation of the Stackelberg game, which includes the use of incentive strategies. First, a configuration in which a supplier announces an incentive function and (Formula presented.) -consumers’ reaction to the resulting personalised price is presented. Then, a detailed st…
¿Revuelta de Masaniello o revolución de Nápoles? Una reinterpretación
2020
Between 7 and 16 July 1647 a popular revolt, led by a young fishmonger, Masaniello, shook the city of Naples. The killing of Masaniello, however, did not lead to the end of the riots. On the contrary, the revolt involved the entire kingdom of Naples, radicalized in an anti-Spanish sense and resulted in the proclamation of the Republic and the call of a French prince, the Duke of Guisa. On these events, and especially on the fracture that permanently opposed people and nobles, historiography has long debated. It is possible, however, today, also on the basis of new archival documents, to propose a different interpretation of the events, which integrates the two moments and allows an updated …
Chile Revolts: From the Uprisings to the Constitutional Process
2022
It is a warm, austral spring Monday in the Capital of Chile. Metro stations are tingling with students and workers ready to encapsulate themselves in underground trains to commute as usual. The ticket fee has just been raised by 30 pesos. A group of young people decide to protest evading the fare. Placing their hands on the turnstile columns, one by one, they leap over the metal bar. This small gesture of disobedience spreads and intensifies with tremendous speed. On October 18, 2019, the government orders to close the entire Santiago subway. It is the day designated as the incipit of the estallido social, the Chilean social outbreak. This modest pretext is the fuse that set off a far-reach…
Hybris e rivoluzione. Il caso della rivolta cilena
2023
This paper discusses the binomial hybris and revolution. In particular, the question of whether the excessive dominants’ arrogance, who have too much both in material and symbolic terms, is sufficient to explain the deflagration of an insurgency and the interruption of a legal order. The question will be addressed by interweaving the reflections of authors who have discussed this topic with a material collected by the author through a legal-political ethnography conducted in Chile during the revolt that broke out in October 2019 and led to a new constituent phase. Categories and definitions used in this text are partly borrowed from the course devoted to political change and revolution taug…
I volti della caricatura
2022
Guardare una caricatura significa innanzitutto riconoscere un determinato soggetto ed essere consapevoli che alcune delle sue caratteristiche sono state significativamente esagerate. In questa relazione mi propongo di esplorare la fenomenologia di questa modalità raffigurativa cercando di fare chiarezza intorno (i) al soggetto della caricatura e (ii) al modo in cui l’esagerazione pittorica viene impiegata per raffigurare. Questi due problemi investono grossomodo il cosa e il come di quest’arte. Una loro disamina consentirà inoltre (iii) di tracciare, nei limiti del possibile, una linea di confine rispetto a un genere figurativo affine: il grottesco.
Biografic turning point in lifetime of individuals living in degraded contexts. The role of resilience.
2020
In the course of their lives all people experience events such as the loss of a parent, a child, job or sometimes violence, after which life is no longer the same. In these moments the regular, repetitive and comforting course of life changes because the event is the turning point that changes the direction of the subject's lifetime. The paper is focused on a study of 60 cases in which resilience intervenes in the biographies of individuals, living in conditions of socio-spatial marginality and high social vulnerability, to restore the existential imbalance of a biographical discontinuity represented by a traumatic event. The problem of the research focuses on understanding the role of resi…
