Timber framed with masonry infill: a historical anti-seismic device. The Portuguese Pombaline gaiola.
2017
La ricostruzione postsismica e la prevenzione sismica sono stati da sempre un fondamento costruttivo.Questo studio analizza la tipologia costruttiva della gaiola pombalina, un sitema costruttivo e strutturale molto diffuso in Portogallo ma non solo, adottato a Lisbona a seguito del terremoto del 1755. Si analizzano i materiali e le tecniche costruttive, gli elementi utili al rinforzo e consolidamento della struttura muraria, ampiamente diffuso in area mediterranea a partire dal XVIII secolo.Questo sistema costruttivo può e deve anche oggi essere considerato un utile presidio antisismico da riconoscere e preservare da interventi incolti, se non addirittura da incongrue demolizioni. Post-seis…
Conjunctions and syntactic complexity: Development of the use of conjunctions in written learner Finnish
2022
Kielitaidon kehittymistä voidaan tutkia mittaamalla oppijankielen sujuvuutta, tarkkuutta ja kompleksisuutta. Kompleksisuus voidaan määritellä oppijankielen monipuolisuudeksi ja kehittyneisyydeksi, mutta syntaktista kompleksisuutta on kansainvälisessä toisen kielen oppimisen tutkimuksessa tyypillisesti mitattu alisteisiin lauserakenteisiin perustuvilla kvantitatiivisilla mittareilla. Tässä artikkelissa syntaktisen kompleksisuuden kehitystä tutkitaan tarkastelemalla rinnastus- ja alistuskonjunktioiden käyttöä suomi toisena kielenä -teksteissä Eurooppalaisen viitekehyksen eri taitotasoilla. Aineistona käytetään Jyväskylän yliopiston Cefling-hankkeen oppijansuomen korpuksen tekstejä. Rinnasteis…
Anonymization as homeomorphic data space transformation for privacy-preserving deep learning
2021
Industry 4.0 is largely data-driven nowadays. Owners of the data, on the one hand, want to get added value from the data by using remote artificial intelligence tools as services, on the other hand, they concern on privacy of their data within external premises. Ideal solution for this challenge would be such anonymization of the data, which makes the data safe in remote servers and, at the same time, leaves the opportunity for the machine learning algorithms to capture useful patterns from the data. In this paper, we take the problem of supervised machine learning with deep feedforward neural nets and provide an anonymization algorithm (based on the homeomorphic data space transformation),…
Phase equilibria of Pantelleria trachytes (Italy): constraints on pre-eruptive conditions and on the metaluminous to peralkaline transition in silici…
2018
Pantelleria Island is the type locality of pantellerite, an iron and alkali-rich rhyolite (P.I=molar Na2O+K2O/Al2O3 >1.05). Peralkaline rhyolites (i.e pantellerite and comendite) and trachytes usually represent the felsic end-members in continental rift systems (e.g., Pantelleria, Tibesti, Ethiopia, Afar, Kenya, Bain and Range, South Greenland) and in oceanic sland settings (Socorro Is., Easter Is., Iceland and Azores). The origin of peralkaline rhyolites in the different tectonic settings is still a matter of debate and three hypotheses have been suggested: (a) crystal fractionation of alkali-basalt in a shallow reservoir to produce a trachyte which subsequently gives rise to a pantelle…
Konfigurowanie granic gatunkowych a problem polityczności. Przypadek posthumanizmu i transhumanizmu
2017
Przedmiotem artykułu są teoriopolityczne rozważania na temat posthumanizmu. Jest to podejście, które zrywa z humanistycznym dogmatem, że człowiek jest bytem najważniejszym w rzeczywistości. Zamiast tego posthumanizm dowartościowuje byty pozaludzkie (naturalne, sztuczne, rzeczy), z którymi ludzie wchodzą w rozmaite interakcje. Autor uznał, że problematyka posthumanistyczna może być rozpatrywana w perspektywie biopolityki, która zajmuje się relacjami między polityką a życiem. Jednakże w odróżnieniu od wcześniejszych ujęć wiążących biopolitykę z kontrolą populacji posthumanizm stawia na szali żywotność gatunkową. W artykule przedstawiono konsekwencje takiego myślenia dla problemu polityczności…
Social accounting and its contribution to society
2013
With the development of the society and its economic system, a need has emerged to develop accounting as well. The increasing role of social accounting, which keeps records of for-profit, non-profit, and governmental organisations, is associated with the complexity of the environment in which businesses and organisations are operating and presenting reports about their social, ethical, and environmental aspects. Organisations are subject to greater transparency, and many stakeholders are interested in and concerned about the performance of organisations within the context that is not reflected, to a satisfactory extent, in traditional accounting. Traditional accounting ensures reporting to …

Spatial and temporal variability of rainfall over the Republic of Djibouti from 1946 to 2017.
2021
20 pages; International audience; For the first time, the spatial and temporal variability of rainfall in the Republic of Djibouti is investigated using data from 14 weather stations over the period 1946–2017. Due to limited data availability, high-resolution long-term satellite rainfall products (CHIRPS, PERSIANN-CDR, TAMSATv3, ARC2) and ERA5 reanalysis also contribute to document time–space rainfall variability at monthly, seasonal and annual scales. Principal component analysis identifies two spatially coherent regions of rainfall variability in the east (coastal zone) and the west (inland zone) of the country. Annual rainfall amounts are everywhere very low (60–300 mm), but with contras…
Stationary, Second Use Battery Energy Storage Systems and Their Applications: A Research Review
2021
The global demand for electricity is rising due to the increased electrification of multiple sectors of economic activity and an increased focus on sustainable consumption. Simultaneously, the share of cleaner electricity generated by transient, renewable sources such as wind and solar energy is increasing. This has made additional buffer capacities for electrical grids necessary. Battery energy storage systems have been investigated as storage solutions due to their responsiveness, efficiency, and scalability. Storage systems based on the second use of discarded electric vehicle batteries have been identified as cost-efficient and sustainable alternatives to first use battery storage syste…
Board structures, liberal countries, and developed market economies. Do they matter in environmental reporting? An international outlook
2019
This is the pre-peer reviewed version of the following article: Board structures, liberal countries, and developed market economies. Do they matter in environmental reporting? An international outlook, which has been published in final form at: https://doi.org/10.1002/bse.2275. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions. Previous empirical evidence has shown the effect of most corporate governance mechanisms on corporate social responsibility and environmental disclosure. However, there is scant empirical evidence that examines the influence of liberal countries, developed market economies, and board s…
