Time Difference of Arrival Estimation from Frequency-Sliding Generalized Cross-Correlations Using Convolutional Neural Networks

2020

The interest in deep learning methods for solving traditional signal processing tasks has been steadily growing in the last years. Time delay estimation (TDE) in adverse scenarios is a challenging problem, where classical approaches based on generalized cross-correlations (GCCs) have been widely used for decades. Recently, the frequency-sliding GCC (FS-GCC) was proposed as a novel technique for TDE based on a sub-band analysis of the cross-power spectrum phase, providing a structured two-dimensional representation of the time delay information contained across different frequency bands. Inspired by deep-learning-based image denoising solutions, we propose in this paper the use of convolutio…

Quantum Toda Lattice: a Challenge for Representation Theory

2021

Quantum Toda lattice may solved by means of the Representation Theory of semisimple Lie groups, or alternatively by using the technique of the Quantum Inverse Scattering Method. A comparison of the two approaches, which is the purpose of the present review article, sheds a new light on Representation Theory and leads to a number of challenging questions.

Companies’ Selection Methods for Inclusion in Sustainable Indices: A Fuzzy Approach

2017

Sustainability indices handle concepts which are both, of numerical and non-numerical nature. In this context, the use of Fuzzy Logic is highly useful as allows a more faithful representation of reality. Usually these indices follow a three-step process to define sustainable investment universes. First step consists of sustainability assessment. In the second step, assets are rated based on the previously assessed sustainability scores and finally, best assets are selected. This last step relies on the construction of a global score reflecting the performance of the assets in main sustainability dimensions. In this Chapter we are concerned with the third step of the selection process. We re…

Inferences are just folk psychology

2004

To speak of “inferences,” “interpretations,” and so forth is just folk psychology. It creates new homunculi, and it is also implausible from a purely phenomenological perspective. Phenomenal volition must be described in the conceptual framework of an empirically plausible theory of mental representation. It is a non sequitur to conclude from dissociability that the functional properties determining phenomenal volition never make a causal contribution. I have offered an alternative interpretation of some of Dan Wegner’s most relevant data elsewhere (Metzinger 2003, p. 506ff), and will confine myself to three conceptual points here. Wegner’s project could be further strengthened by eliminati…

"She's straight, you delusional cunt!" : a study on bullying and homophobia in online fandoms

2016

Tämä kandidaatintutkielma käsittelee seksuaalisten vähemmistöjen syrjintää ja nettikiusaamisen esiintymistä internet-faniyhteisöissä. Edelliset tutkimukset kertovat nettikiusaamisen olevan haitallista ja vaikuttavan uhrien mielenterveyteen – usein jopa enemmän kuin kasvotusten tapahtuva kiusaaminen. Tutkielmaa varten tehty nettikysely suunnattiin “femslash”-faniryhmille. Näiden ryhmien median kulutukseen kuuluvat esimerkiksi tv-ohjelmien naishahmojen väliset (romanttiset) suhteet ja näistä suhteista puhuminen sekä eri materiaalien (kuten kuvien, videoiden ja fanifiktion) luominen ryhmien henkilöiden kesken. Kyselyn perusteella oli tarkoitus saada selville, miten yleistä näiden ryhmien kokem…

Vehicle localization based on scene perception

2021

The vision-based vehicle localization task is tackled as an image-based place recognition problem in this thesis. As image representation is an important process to place recognition, we proposed place recognition methods focusing on increasing the quality of image features. First, the dynamic object removal step is proposed to remove the dynamic objects, such as vehicles and pedestrians, of an image by semantic segmentation method and restore their background information by image inpainting method. Second, reducing instead of removing the noisy information of an image is proposed. Using the image blurring method to reduce the image noise, the performance of place recognition is improved wi…

Dentro il processo: narrazioni, numeri e spazi del femminicidio nel discorso giudiziario

2020

Il saggio espone i primi risultati di una ricerca sulle rappresentazioni del femminicidio in ambito giudiziario in Italia, illustrandone il quadro teorico, le scelte metodologiche, l’impianto analitico, gli strumenti. Le problematiche connesse all’uso del termine femminicidio sono esplorate ponendo al centro il processo normativo, esplorandone i significati sociali e questionando gli ancoraggi politici e economici, attraverso il modello del “campo giuridico”. Mediante l’analisi di un corpus di 370 sentenze, andate in giudizio tra il 2010 e il 2016 e attraverso la conduzione di 30 interviste ad altrettanti testimoni privilegiati il discorso giuridico sulla violenza di genere è criticamente s…

Characterization of nuclear effects in muon-neutrino scattering on hydrocarbon with a measurement of final-state kinematics and correlations in charg…

2018

This paper reports measurements of final-state proton multiplicity, muon and proton kinematics, and their correlations in charged-current pionless neutrino interactions, measured by the T2K ND280 near detector in its plastic scintillator (C$_8$H$_8$) target. The data were taken between years 2010 and 2013, corresponding to approximately 6$\times10^{20}$ protons on target. Thanks to their exploration of the proton kinematics and of kinematic imbalances between the proton and muon kinematics, the results offer a novel probe of the nuclear-medium effects most pertinent to the (sub-)GeV neutrino-nucleus interactions that are used in accelerator-based long-baseline neutrino oscillation measureme…
