Simplified Energy Model and Multi-Objective Energy Consumption Optimization of a Residential House

2022

Featured Application: The potential application of the proposed model is a computationally inexpensive semi- or fully automated system for the optimization of operation in residential buildings in terms of energy consumption. Some analyses state that buildings contribute to overall energy consumption by 20–40%, which, in the context of the recent geopolitical energy crisis, makes them a critical issue to study. Finding solutions for better energy management in buildings can have a significant impact on the energy sector, thus reducing EU energy dependencies and contributing to the fulfillment of the REPowerEU goals. This paper focuses on proposing a simplified model of a residential house c…

A pre-processing and network analysis of GPS tracking data

2020

Global Positioning System (GPS) devices afford the opportunity to collect accurate data on unit movements from temporal and spatial perspectives. With a special focus on GPS technology in travel surveys, this paper proposes: (1) two algorithms for the pre-processing of GPS data in order to deal with outlier identification and missing data imputation; (2) a clustering approach to recover the main points of interest from GPS trajectories; and (3) a weighted-directed network, which incorporates the most relevant characteristics of the GPS trajectories at an aggregate level. A simulation study shows the goodness-of-fit of the imputation data algorithm and the robustness of the clustering algori…

Optimization of Cultural Heritage Virtual Environments for Gaming Applications

2020

Serious games are games with a purpose beyond entertainment and are widely acknowledged as fruitful tools for learning and developing skills across multiple domains, including educational enhancement. In the last few years, the world of serious games has widely increased. The use of these types of games can aid in classrooms to not only help the students learn concepts but also to improve their motivation to do so. However, designing games necessitates very specialized personnel and the process can often be costly and slow. The adaptions of the design to the implantation phase are also difficult and the process needs more focus. The challenge of this study was to create a game within the co…

Using SMAA-2 method with dependent uncertainties for strategic forest planning

2006

Abstract Uncertainty included in forest variables is normally ignored in forest management planning. When the uncertainty is accounted for, it is typically assumed to be independently distributed for the criteria measurements of different alternatives. In forest management planning, the factors introducing the uncertainty can be classified into three main sources: the errors in the basic forestry data, the uncertainty of the (relative) future prices of timber, and the uncertainty in predicting the forest development. Due to the nature of these error sources, most of the involved uncertainties can be assumed to be positively correlated across the alternative management plans and/or criteria.…

Identification and Robust Control of a Quadratic DC/DC Boost Converter by Hammerstein Model

2015

This paper deals with the theoretical framework definition and the experimental application of the Hammerstein (HM) identification and related robust control technique to a quadratic dc/dc single-switch boost (Q-boost) converter. A set of fourth-order transfer functions (TFs) has been identified with the Hammerstein approach, on the basis of a pseudorandom-binary-sequence (PRBS) excitation signal. The set of identified TFs has been then used to design a suitable robust control technique, able to properly deal with the converter parameter uncertainty and load variations. The proposed approach has been tested in numerical simulation and validated experimentally on a suitably developed test se…

Incitación al terrorismo y libertad de expresión: el marco internacional de una relación problemática

2014

La Resolución 1624 (2005) del Consejo de Seguridad de las Naciones Unidas no define la incitación al terrorismo. Sí lo hace, por el contrario, el Convenio núm. 196 del Consejo de Europa de 2005 que caracteriza la provocación pública al terrorismo incluyendo deliberadamente la incitación indirecta, exigiendo una intencionalidad específica y un resultado de peligro de comisión de un delito terrorista. El Informe explicativo del Convenio remite a la jurisprudencia del TEDH para establecer los elementos a considerar en la apreciación de dicho peligro haciendo así de ella un parámetro interpretativo. La Decisión Marco del Consejo de la Unión Europea ha adoptado desde 2008 la misma definición que…

Functional principal component analysis for multivariate multidimensional environmental data

2015

Data with spatio-temporal structure can arise in many contexts, therefore a considerable interest in modelling these data has been generated, but the complexity of spatio-temporal models, together with the size of the dataset, results in a challenging task. The modelization is even more complex in presence of multivariate data. Since some modelling problems are more natural to think through in functional terms, even if only a finite number of observations is available, treating the data as functional can be useful (Berrendero et al. in Comput Stat Data Anal 55:2619–2634, 2011). Although in Ramsay and Silverman (Functional data analysis, 2nd edn. Springer, New York, 2005) the case of multiva…

Fusion of multimodal data by combining the uncertainty and perception models

2019

The general idea is to use together heterogeneous multiple information on the same problem tainted by imperfections and coming from several sources in order to improve the knowledge of a given situation. Appropriate visualization of the images to aid in decision making using the perceptual information carried by the salience maps.

Vertaisarvioinnin harjoitusohjelma ja vertaisarviointien toteutus Ketosen väitöskirjassa

2021

Tämä materiaali on suomenkielinen kuvaus vertaisarviointi-intervention toteutuksesta Ketosen (2021) väitöskirjassa. Toteutus sisältää vertaisarvioinnin harjoituksia ja varsinaisia vertaisarviointeja. Interventio kesti 1,5 vuotta ja se toteutettiin fysiikan ja kemian oppiaineissa luokka-asteilla 7-8 vuosien 2018-2019 aikana. Harjoitukset ja vertaisarvioinnit on materiaalissa kuvattu siinä järjestyksessä, jossa ne tutkimuksessa toteutettiin. Interventio suunniteltiin vertaisarvioinnin aiempaa tutkimustietoa peruskoulun kontekstiin soveltaen. Materiaali toimii esimerkkinä siitä, miten vertaisarviointia voi harjoitella ja toteuttaa peruskoulussa osana oppiaineen opiskelua. This material is a de…

GIORNALISMO E VETRINIZZAZIONE SOCIALE. LE DERIVE DELLA LOGICA SPETTACOLARE IN ITALIA

2014

The article focuses on the development of a television market model in Italian journalism in the last two decades, characterized by the success of the "entertainment" frame in both TV and print news. The use of a spectacular framing and commercialization of news has its roots in the American popular journalism of the 1800s, but is today connected to the more recent of a «Showcase» (or «display window») communication model. Each place is or can be a stage, and the traditional definition of news is revised: journalism does not present news objectively, but it offers dramatized reconstructions of parts of reality, focusing on the visual impact of the events and on the narrative strategy used t…
