An online grey-box model based on unscented kalman filter to predict temperature profiles in smart buildings
No full textNearly 40% of primary energy consumption is related to the usage of energy in Buildings. Energy-related data such as indoor air temperature and power consumption of heating/cooling systems can be now collected due to the widespread diffusion of Internet-of-Things devices. Such energy data can be used (i) to train data-driven models than learn the thermal properties of buildings and (ii) to predict indoor temperature evolution. In this paper, we present a Grey-box model to estimate thermal dynamics in buildings based on Unscented Kalman Filter and thermal network representation. The proposed methodology has been applied in two different buildings with two different thermal network discretizations to test its accuracy in indoor air temperature prediction. Due to a lack of a real-world data sampled by Internet of Things (IoT) devices, a realistic data-set has been generated using the software Energy+, by referring to real industrial building models. Results on synthetic and realistic data show the accuracy of the proposed methodology in predicting indoor temperature trends up to the next 24 h with a maximum error lower than 2 °C, considering one year of data with different weather conditions

No full textBuildings are responsible of about 40% of primary energy consumption. The widespread diffusion of Internet-of-Things devices provide allow collecting large amount of energy related data such as indoor air-temperature and power consumption of heating/cooling systems. Collected information can be used to develop data-driven models to learn building characteristics and to forecast indoor temperature trends. In this paper, we present a Grey-box model to estimate thermal dynamics in buildings based on Unscented Kalman Filter and thermal network representation. The proposed methodology has been applied to different implementation of building thermal networks to test their accuracy in temperature prediction. Results show the accuracy of the proposed methodology in predicting indoor temperature trends up to next 24-hours with a maximum error of 1.50°C
Development and validation of advanced analytical methods for alcohol biomarkers’ analysis and application on real samples from cancer patients
No full textQuesto lavoro si propone di sviluppare un metodo di analisi in GC-EI-MS/MS per la quantificazione dell’EtG su matrice cheratinica, attraverso un approfondito lavoro di design sperimentale per l’ottimizzazione delle condizioni di pretrattamento ed estrazione del campione. Il metodo validato ed ottimizzato viene quindi applicato su una serie di campioni reali per valutarne l’adeguatezza nel fornire risultati che possano essere correlati con le abitudini dichiarate dai soggetti sottoposti ad analisi. La bontà del metodo viene ulteriormente valutata confrontando i dati ottenuti con quelli ottenuti da un secondo metodo, già validato ed in uso presso il Centro Anti Doping di Orbassano.
Un secondo metodo di analisi per il fosfatidil etanolo su sangue capillare viene a sua volta sviluppato con una metodica UHPLC-ESI-MS/MS. Il metodo è stato utilizzato per analizzare campioni di sangue prelevati da alcuni soggetti per cui l’analisi dell’EtG nei capelli era già stata portata a termine. Questa fase ha permesso di valutare la correlazione tra i dati ottenuti per due marcatori diretti del consumo di alcol su due matrici, permettendo una valutazione del comportamento dei soggetti sul medio e sul lungo termine. Questa fase dello studio riveste particolare interesse, dal momento che correla dati ottenuti su matrici diverse e per analiti diversi con tecniche differenti, dimostrando che entrambi i marcatori sono adatti a valutare e categorizzare i soggetti in base al loro comportamento alcolico. L’analisi dei data è stata svolta con sofware di calcolo come Excell ed R, servendosi di metodi statistici avanzati come il design sperimentale, l’utilizzo di box plot, l’analisi dei cluster e svariati test di significatività statistica.
Per finire, entrambi i metodi sviluppati sono stati applicati a campioni di soggetti affetti da neoplasie delle vie digestive e respiratorie superiori, ovvero tumori al cavo orale, alla lingua, all’orofaringe, all’ipofaringe ed alla laringe. Lo sviluppo della malattia, la prognosi e la speranza di vita sono state correlate con i valori degli indicatori di consumo alcolico, con la speranza di evidenziare una correlazione tra questi parametri e gli stili di vita dei pazienti antecedenti alla diagnosi

El desarrollo de la novela en Inglaterra : Oroonoko, un antecedente inmediato
No full textAunque el debate sobre géneros es reciente (a comienzos del siglo XIX), y de esta forma la noción de género en la época de Oroonoko era considerar a los distintos géneros como estáticos (categorías universales que no cambiaban a través del tiempo), este análisis se basará en la concepción moderna de género que se refiere al carácter histórico de los mismos, ya que no se puede desprender al género del entorno socio-histórico que lo contiene y lo define. De esta forma se dejará de lado la caracterización clásica de los géneros y la misma será reemplazada por una nueva concepción: los géneros están históricamente determinados y son entidades dinámicas. Desde sus comienzos, la novela, se ha encontrado con problemas para encuadrar dentro de ciertas categorías literarias. Como el crítico ruso M. Bakhtin explica en su ensayo The Problem of Speech Genres: ?la novela es una criatura de una especie extraña?. Este hecho es mucho más notorio en sus orígenes, cuando el género emerge tratando de moldearse a sí mismo, tratando de encontrar identidad propia. Este es el caso de Oroonoko, un híbrido en el proceso de tomar forma. ¿Será justo, entonces, encorsetarlo siguiendo el parámetro de un género ahora socialmente establecido, como puede ser la crónica, la nouvelle o el cuento? ¿O podrá ser tomado como el antecedente más inmediato del género por excelencia que va a reflejar y a la vez moldear la sociedad? Este trabajo basará su análisis de Oroonoko en las características del género novela y la teoría de los paradigmas de Khun previamente formulada. Seguirá también el análisis de Watt de los cambios más importantes en la novela y el mismo será aplicado a Oroonoko para mostrar que es un antecedente inmediato de la novela y que su género no puede ser específicamente definido ya que se encuentra en el proceso de desarrollo.Fil: Massano, Constanza.

Azathioprine monotherapy withdrawal in inflammatory bowel diseases: A retrospective mono-centric study
No full textBackground: There is no consensus on the recommended duration of and optimal time to stop azathioprine (AZA) therapy in inflammatory bowel disease (IBD). Determining the optimal duration and cessation time can help to balance the risks of long-term intake with the possibility of relapse after cessation. Aim: To describe the events following AZA cessation. Methods: Retrospective analysis was performed to examine data from adult patients affected by IBD who were followed at the University of Padua and had started but then discontinued AZA between 1995 and 2022. Data on therapy duration, reasons for cessation, and type of relapse after cessation were collected. Cox regression models were used to estimate the risk of relapse in different subgroups. Results: A total of 133 ulcerative colitis patients and 141 Crohn's disease patients were included. Therapy with AZA was stopped in the 1st year in approximately 34% of patients but was continued for more than 10 years in approximately 10% of cases. AZA discontinuation was due to primary failure or disease relapse in 30% of patients and due to disease remission in 25.2% of patients. Most of the remaining cases stopped AZA therapy due to side effects (primarily clinical intolerance, cytopenia, and pancreatic disease). Patients who stopped AZA for clinical remission had an 83% lower risk of relapse during the observation time than other groups, with a relapse-free rate of 89% after 1 year and 79% after 2 years. Conclusion: AZA administration is effective and safe, but it requires careful monitoring for potential minor and major side effects. Only 10% of patients who achieved remission with AZA needed a new treatment within 1 year of drug interruption
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
