An EEMD Aided Comparison of Time Histories and Its Application in Vehicle Safety
2017
In the context of signal processing, the comparison of time histories is required for different purposes, especially for the model validation of vehicle safety. Most of the existing metrics focus on the mathematical value only. Therefore, they suffer the measuring errors, disturbance, and uncertainties and can hardly achieve a stable result with a clear physical interpretation. This paper proposes a novel scheme of time histories comparison to be used in vehicle safety analysis. More specifically, each signal for comparison is decomposed into a trend signal and several intrinsic mode functions (IMFs) by ensemble empirical mode decomposition. The trend signals reflect the general variation a…
Dynamic Functional Connectivity in the Musical Brain
2019
Musical training causes structural and functional changes in the brain due to its sensory-motor demands. This leads to differences in how musicians perceive and process music as compared to non-musicians, thereby providing insights into brain adaptations and plasticity. Correlational studies and network analysis investigations have indicated the presence of large-scale brain networks involved in the processing of music and have highlighted differences between musicians and non-musicians. However, studies on functional connectivity in the brain during music listening tasks have thus far focused solely on static network analysis. Dynamic Functional Connectivity (DFC) studies have lately been …
Evaluation of radiological findings with COVID-19 lung lesions in Latvia in the view of artificial intelligence and radiologist
2022
Pēc Pasaules Veselības organizācijas datiem kopš pandēmijas sākuma kopējais ar Covid-19 saslimušo cilvēku skaits pārsniedz 500 miljonus. Mākslīgais intelekts (MI) paver plašas iespējas Covid-19 infekcijas izraisīto plaušu bojājumu diagnostikā, kas var uzlabot un atvieglojot radiologa darbu veicinot gan izmeklējuma specifitātes, gan sensitivitātes izvērtēšanas iespējas. Šī pētījuma galvenais mērķis bija salīdzināt MI un radiologa atradnes precizitāti Covid-19 radītā plaušu bojājuma izvērtēšanā un noteikt interpretācijas ierobežojumus un priekšrocības klīniskā kontekstā. Savukārt darba uzdevumi bija iepazīties un apkopot datus ar jaunāko literatūru par MI pielietošanas iespējām medicīnā. Apko…
Machine Learning Models for Measuring Syntax Complexity of English Text
2019
In this paper we propose a methodology to assess the syntax complexity of a sentence representing it as sequence of parts-of-speech and comparing Recurrent Neural Networks and Support Vector Machine. We have carried out experiments in English language which are compared with previous results obtained for the Italian one.
A Navigation and Augmented Reality System for Visually Impaired People
2021
In recent years, we have assisted with an impressive advance in augmented reality systems and computer vision algorithms, based on image processing and artificial intelligence. Thanks to these technologies, mainstream smartphones are able to estimate their own motion in 3D space with high accuracy. In this paper, we exploit such technologies to support the autonomous mobility of people with visual disabilities, identifying pre-defined virtual paths and providing context information, reducing the distance between the digital and real worlds. In particular, we present ARIANNA+, an extension of ARIANNA, a system explicitly designed for visually impaired people for indoor and outdoor localizati…
Tecnologie Robotiche e responsabilità extracontrattuale: un'analisi comparata
2022
Attraverso un esame delle soluzioni giuridiche derivanti, da un lato, dal percorso normativo posto in essere dall’Unione Europea e, dall’altro lato, da quanto emerge dal case law in via di formazione nel mondo, con questo lavoro si vuole dimostrare che l’avvento delle tecnologie robotiche non comporta necessariamente l'individuazione di nuove categorie giuridiche né induce mutamenti radicali nel sistema consolidato dei principi della responsabilità civile. In questa prospettiva si vuole verificare se il ricorso alla categoria della responsabilità oggettiva possa consentire un livello di tutela adeguato del danneggiato senza per ciò stesso limitare o incidere negativamente sulla opera di inn…
