Introduction to Gestural Similarity in Music. An Application of Category Theory to the Orchestra

2019

Mathematics, and more generally computational sciences, intervene in several aspects of music. Mathematics describes the acoustics of the sounds giving formal tools to physics, and the matter of music itself in terms of compositional structures and strategies. Mathematics can also be applied to the entire making of music, from the score to the performance, connecting compositional structures to acoustical reality of sounds. Moreover, the precise concept of gesture has a decisive role in understanding musical performance. In this paper, we apply some concepts of category theory to compare gestures of orchestral musicians, and to investigate the relationship between orchestra and conductor, a…

Assessment of allyl isothiocyanate as a fumigant to avoid mycotoxin production during corn storage

2016

The occurrence of fungi and mycotoxins in foods modify sensorial properties and represents a health risk for consumers, and the use of natural antimicrobials may be an alternative to reduce this problem. The objective of this study was evaluate the potential of allyl isothiocyanate (AITC) in inhibit the production of mycotoxins in corn kernels by Aspergillus parasticus, Fusarium tricinctum, Fusarium verticillioides, Alternaria alternata and Gibberela zeae. Kernels were treated with gaseous AITC at 50, 100 or 500 μL/L during 48 h in hermetic flasks. Then, flasks were opened for 24 h and 100 g of corn were inoculated with 105 conidia/g of either fungal species. Flasks were kept at 23 °…

The many faces of human sociality: uncovering the distribution and stability of social preferences

2018

There is vast heterogeneity in the human willingness to weigh others' interests in decision making. This heterogeneity concerns the motivational intricacies as well as the strength of other-regarding behaviors, and raises the question how one can parsimoniously model and characterize heterogeneity across several dimensions of social preferences while still being able to predict behavior over time and across situations. We tackle this task with an experiment and a structural model of preferences that allows us to simultaneously estimate outcome-based and reciprocity-based social preferences. We find that non-selfish preferences are the rule rather than the exception. Neither at the level of …

Starppriekšmetu un savstarpējās sadarbības projekti angļu valodas rakstīšanas prasmju pilnveidei 9.klasē

2022

Sākoties jaunajam mācību gadam, pakāpeniska jaunā mācību satura ieviešana ir kļuvusi par vienu no svarīgākajām sarunu tēmām skolās. Projekta Skola2030 mērķis bija attīstīt skolēniem vairākas svarīgas 21. gadsimta prasmes, kā arī koncentrēt uzmanību uz mācību priekšmetu padziļinātu izpratni un padziļināti izprast mācību vielu nevis sadrumstaloti. 2020./2021. mācību gadu skolēni pavadīja attālināti, un tas sagādāja grūtības attīstīt rakstīšanas prasmes angļu valodas mācību stundās. Tāpēc tika izvēlēta daudznozaru un savstarpējās sadarbības pieeja, lai attīstītu visas nepieciešamās prasmes. Tika veikts gadījuma pētījums, kurā piedalījās 14 skolēni no 9. klases, 7 dažādu mācību priekšmetu skolo…

Multisensory texture exploration at the tip of the pen

2016

A tool for the multisensory stylus-based exploration of virtual textures was used to investigate how different feedback modalities (static or dynamically deformed images, vibration, sound) affect exploratory gestures. To this end, we ran an experiment where participants had to steer a path with the stylus through a curved corridor on the surface of a graphic tablet/display, and we measured steering time, dispersion of trajectories, and applied force. Despite the variety of subjective impressions elicited by the different feedback conditions, we found that only nonvisual feedback induced significant variations in trajectories and an increase in movement time. In a post-experiment, using a pa…

SAMSLAM: Simulated Annealing Monocular SLAM

2013

This paper proposes a novel monocular SLAM approach. For a triplet of successive keyframes, the approach inteleaves the registration of the three 3D maps associated to each image pair in the triplet and the refinement of the corresponding poses, by progressively limiting the allowable reprojection error according to a simulated annealing scheme. This approach computes only local overlapping maps of almost constant size, thus avoiding problems of 3D map growth. It does not require global optimization, loop closure and back-correction of the poses.
