Signal processing techniques for robust sound event recognition
2019
The computational analysis of acoustic scenes is today a topic of major interest, with a growing community focused on designing machines capable of identifying and understanding the sounds produced in our environment, similar to how humans perform this task. Although these domains have not reached the industrial popularity of other related audio domains, such as speech recognition or music analysis, applications designed to identify the occurrence of sounds in a given scenario are rapidly increasing. These applications are usually limited to a set of sound classes, which must be defined beforehand. In order to train sound classification models, representative sets of sound events are record…
Revealing colonial power relations in early childhood policy making: An autoethnographic story on selective evidence
2021
The COVID-19 pandemic exposes uncertainty, instability and glaring inequality that requires urgent global policy decisions. Historically, bureaucrats regard uncertainty as the enemy and look for tested solutions (Stevens, 2011). In contrast, Fielding & Moss (2010) acknowledge an uncertain future and encourage shifting policy making towards the search for possibilities instead of replicating singular solutions. Escobar (2020) advocates for pluriversal politics, with many possibilities created through collective decision-making by autonomous interlinked networks. In this paper, I combine autoethnography with policy analysis drawing on my own experience in South African early childhood pol…
Ultra Reliable Communication in 5G Networks: A Dependability-based Availability Analysis in the Space Domain
2017
Master's thesis Information- and communication technology IKT591 - University of Agder 2017 As our daily life is becoming more dependent on wireless and mobile services, seamless network connectivity is of utmost importance. Wireless networks are expected to handle the growing demand for applications which require higher capacity, without failure. Therein, wireless connectivity is regarded as an essential requirement for a wide range of applications in order to support exible and cost-e ective services. As part of the fth generation (5G) communication paradigm, ultra reliable communication (URC) is envisaged as an important technology pillar for providing anywhere and anytime services to en…

Specie arboree esotiche invasive: il caso di Robinia e Ailanto
2019
Le specie arboree esotiche invasive non di rado rappresentano una quota significativa della composizione dendrologica dei boschi di neoformazione e preoccupano per gli impatti che possono causare sulla biodiversità. Recentemente, il timore riguarda i possibili effetti causati agli ecosistemi boschivi: infatti, gli ecosistemi forestali e quelli a essi contigui, come pascoli e prati permanenti, apparentemente più resilienti rispetto ad altri tipi di ecosistemi, ne subiscono l'aggressività in modo significativo e, anche in forza di provvedimenti legislativi, la pianificazione e gestione silvopastorale è chiamata a prestare sempre più attenzione a questo tema.

Seasonal variation in diversity of marine benthic invertebrates leads to a positive species-genetic diversity correlation (SGDC)
2018
Species-genetic diversity correlations (SGDCs) are useful indicators of processes that simultaneously affect diversity at multiple biological levels. We combined spatial and temporal sampling of 4 study sites in the Danish Isefjord-Roskilde Fjord Estuary at 4 time points over 1 yr to investigate the effect of seasonal variation on SGDCs. Species diversity was estimated as species richness from samples comprising 20752 individuals representing 51 benthic invertebrate taxa. Genetic diversity was estimated for a single focal taxon, the polychaete Pygospio elegans, as mean allelic richness at 7 microsatellite loci. Combining all samples, a significant positive correlation between species richne…
Intelligent solutions for real-life data-driven applications
2017
The subject of this thesis belongs to the topic of machine learning or, specifically, to the development of advanced methods for regression analysis, clustering, and anomaly detection. Industry is constantly seeking improved production practices and minimized production time and costs. In connection to this, several industrial case studies are presented in which mathematical models for predicting paper quality were proposed. The most important variables for the prediction models are selected based on information-theoretic measures and regression trees approach. The rest of the original papers are devoted to unsupervised machine learning. The main focus is developing advanced spectral cluster…
Two new organic-selenate salts: syntheses and crystal structures of bis(di-iso-propylammonium) selenate and di-n-butylammonium hydrogenoselenate
2017
Abstract Two new dialkyammonium selenate salts [i-Pr2NH2]2[SeO4] (1) and [n-Bu2NH2][HSeO4] (2) have been isolated and characterized by single-crystal X-ray diffraction. Salt 1 crystallizes in the monoclinic system, space group P21/n with a=8.7190(5), b=8.8500(4), c=22.5953(9) Å, β=94.6290(17)°, V=1737.84(14) Å3 and Z=4. Salt 2 crystallizes in the monoclinic system space group P21/n with a=10.9328(9), b=8.1700(6), c=13.8095(11) Å, β=97.130(3)°, V=1223.94(17) Å3 and Z=4. In both salts, dialkylammonium cations and selenate anions are connected through NH···O and OH···O hydrogen bonds. In the crystal structure, 1 and 2 are organized in layer-like arrangements. Structural characterizations were …
