VegItaly: Technical features, crucial issues and some solutions
2012
VegItaly is at present the largest Italian vegetation database. It is the result of a collaborative project aspiring to represent a major reference for the Italian vegetation scientists. The paper emphasizes its benefits for phytosociological data management and describes the solutions adopted to solve several technical problems, like the treatment of different vegetation stratification systems, the conversion of vegetation cover values, taxonomic and syntaxonomic issues, data import and access. The structure of the taxonomic list produced to support the storing of data is described. It allows an easy management of synonymic relationships and is constantly updated according to new publicati…
Assessment of the Entropy of Spatial and Time Distributions of Rooms Daylighting: A Possible Tool for a Sustainable Design
2015
The indoor visual comfort of subjects faced with indoor ambient lighting varies with the position of the subject and is not constant over time. Average performance indexes, such as the mean value of Daylight Factor and Daylight Autonomy, are commonly used to analyse lighting distribution. These indexes, however, don’t properly take into account either the spatial or the time distribution of values affecting the non-uniformity of environmental lighting. Indeed, these are limited to the definition of a mean value or to the assessment of time availability of daylighting. This paper examines spatial and temporal non-uniformities in indoor lighting as possible causes of discomfort for occupants.…
La controvertida indemnización por lesión de los derechos fundamentales de las personas trabajadoras
2021
El reconocimiento y cuantificación de las indemnizaciones por vulneración de derechos fundamentales en el orden social de la jurisdicción ha sido, desde siempre, y por diferentes razones, una cuestión especialmente compleja. En ciertos casos ¿como sucede con la automaticidad del daño moral derivado de la violación del derecho fundamental- las contradicciones y vaivenes judiciales son ya un ¿clásico¿ en la materia; en otros, las dudas guardan relación con el significado y la repercusión que una incorporación legal efectuada por la LRJS -la finalidad preventiva de la indemnización- debe tener en la práctica judicial; y, finalmente, las discrepancias se refieren a la posibilidad misma de conce…
A comparison of different DC-DC converters for energy storage management in nearly-Zero Energy Buildings
2020
In the recent years, there has been a notable interest towards renewable sources, energy saving and efficiency optimization, in order to reduce the damages brought by fine dust and greenhouse gases in terms of safety, health and environmental protection. In the building sector renewable sources and energy efficiency optimization are leading to a large scale employment of nearly-Zero Energy Buildings (n-ZEBs), meaning that the balance between produced and required energy is negligible. For a proper n-ZEB implementation, a power system architecture has to be accurately designed, according to the existing renewable sources, loads and storage systems. In this paper, an investigation on differen…
A comprehensive analysis for N2O mechanisms by advanced mathematical techniques
2018
Recent evaluation of the existing activated sludge models, incorporating nitrous oxide (N2O) formation, is only based on the capabilities and inabilities in describing experimental data under different conditions. This paper will present an advanced mathematical modeling framework (i.e. coupling global sensitivity, identifiability and uncertainty analysis) for a comprehensive analysis on the evaluation of the structural differences among three ammonia oxidizing bacteria (AOB) two-pathway models in combination with two heterotrophic denitrification models. The analysis will be performed based on experimental data from a lab-scale deammonification granular sequencing batch reactor operated un…
Decision making as a moment of inclusion for students in internship
2018
The vocational training issue today is relevant in the social and political debate to improve the quality of the school system, and to the discussion about the professionalization of education pathways. The new reform law 107/15 art. 1 introduces and regulates the obligation of young apprenticeship program, to be carried out for all students in the last three years of secondary school. The law, which takes over the Legislative Decree 15/4/2005, n. 77 of the application 28/03/2003, n. 53 in which such innovations had been introduced, makes the process compulsory for every student of the secondary school in last three years. The paper presents an exploratory qualitative study design focusing …
Building energy demand assessment through heating degree days: the importance of a climatic dataset
2019
Abstract The weather is one of the main factors to consider when designing a building because it represents the most important boundary condition to affect the dynamic behaviour of the building. In the literature, many studies use the degree day to predict building energy demand. However, linking the results obtained from a generic building simulation tool with defined degree days, will not give reliable energy evaluation. The goal of this study is to demonstrate that the assessment of building energy demand through the use of the degree day is correct only if the determination of the climate index is a function of the same weather data. The relationship between Heating Degree-Day and heati…
Building energy performance forecasting: A multiple linear regression approach
2019
Abstract Different ways to evaluate the building energy balance can be found in literature, including comprehensive techniques, statistical and machine-learning methods and hybrid approaches. The identification of the most suitable approach is important to accelerate the preliminary energy assessment. In the first category, several numerical methods have been developed and implemented in specialised software using different mathematical languages. However, these tools require an expert user and a model calibration. The authors, in order to overcome these limitations, have developed an alternative, reliable linear regression model to determine building energy needs. Starting from a detailed …
Decision-making in energy planning. Application of the Electre method at regional level for the diffusion of renewable energy technology
2003
The authors show an application of the multicriteria decision-making methodology used to assess an action plan for the diffusion of renewable energy technologies at regional scale. This methodological tool gives the decision-maker considerable help in the selection of the most suitable innovative technologies in the energy sector, according to preliminary fixed objectives. In this paper, a case study is carried out for the island of Sardinia. This region presents, on one hand, a high potential for energy resources exploitation, but on the other hand, it represents a specific case among other Italian regions, because of its socio-economic status and history. Three decision scenarios have bee…
Un nuovo approccio per l’integrazione dell’analisi di rischio nella valutazione degli impatti ambientali connessi alle operazioni di smantellamento d…
2018
La disattivazione e lo smantellamento delle installazioni nucleari a seguito della loro cessazione di esercizio è uno dei problemi che molti paesi si trovano ad affrontare avendo come vincolo la garanzia della sostenibilità ambientale e la sicurezza della popolazione e dei lavoratori coinvolti nelle varie procedure operative. Tuttavia, non esiste allo stato attuale una metodologia capace di classificare la rilevanza dei vari tipi di impatto, ma piuttosto una varietà di strategie che dipendono fortemente dalla normativa vigente nel paese di appartenenza. Ciò ha portato a trascurare la definizione di una procedura capace di individuare proattivamente le condizioni di rischio connesse alle att…
