Attractor as a convex combination of a set of attractors

2021

This paper presents an effective approach to constructing numerical attractors of a general class of continuous homogenous dynamical systems: decomposing an attractor as a convex combination of a set of other existing attractors. For this purpose, the convergent Parameter Switching (PS) numerical method is used to integrate the underlying dynamical system. The method is built on a convergent fixed step-size numerical method for ODEs. The paper shows that the PS algorithm, incorporating two binary operations, can be used to approximate any numerical attractor via a convex combination of some existing attractors. Several examples are presented to show the effectiveness of the proposed method.…

Conversational code-switching in a video game context in Finland

2015

Tämän proseminaari-työn tarkoitus on tutkia, millaista suomen ja englannin kielen välillä tapahtuvaa koodinvaihtoa suomalaisessa tietokonepelidiskurssissa on sekä selvittää, pitävätkö keskustelijat itse koodinvaihtoa merkityksellisenä ja mitä merkityksiä se keskustelussa saa. Koodinvaihtoa on tutkittu kieliopillisesta, sosiolingvistisestä, kaksikielisyyden ja keskustelunanalyysin näkökulmasta. Tutkimusala on saanut näkyvyyttä viimeisen kymmenen vuoden aikana muun muassa englannin kielen kasvavan aseman kautta. Suomessa koodinvaihtoa on tutkittu monessa eri kontekstissa fan fictionista radioon ja Internetin jalkapallofoorumeihin. Tämä tutkimus tarkastelee koodinvaihtoa kahden äidinkielenään …

Monitoring Water and Energy Cycles at Climate Scale in the Third Pole Environment (CLIMATE-TPE)

2021

A better understanding of the water and energy cycles at climate scale in the Third Pole Environment is essential for assessing and understanding the causes of changes in the cryosphere and hydrosphere in relation to changes of plateau atmosphere in the Asian monsoon system and for predicting the possible changes in water resources in South and East Asia. This paper reports the following results: (1) A platform of in situ observation stations is briefly described for quantifying the interactions in hydrosphere-pedosphere-atmosphere-cryosphere-biosphere over the Tibetan Plateau. (2) A multiyear in situ L-Band microwave radiometry of land surface processes is used to develop a new microwave r…

Kriptovalūtas un to attīstība

2022

Bakalaura tēma: “Kriptovalūtas un to attīstība”. Tēmas aktualitāte ir saistīta ar kriptovalūtas modi kopš Bitcoin pirmās parādīšanās 2008. gadā. No šī brīža sāka attīstīties jauns potenciālais tirgus, kas mūsdienās ir ikdienas tēma ikvienam finanšu un monetārajā tirgos iesaistītajam. Kriptovalūtas parādījās kā dzīvotspējīga alternatīva tradicionālajām valūtām ar daudziem jauniem raksturojumiem, kā arī vairākiem aspektiem, kas dalās viedokļos starp tiem, kuri to saprot kā lielisku alternatīvu nākotnei, un skeptiskākiem, kuri joprojām apšauba tās likumību un izmantot. Mūsdienās kriptovalūta ir viena no interesantākajām tēmām finanšu tirgos visu ar to saistīto strīdu, kā arī sabiedrības akcept…

Fontaines (Saône-et-Loire). Place de l’Église [notice archéologique]

2019

Le village actuel de Fontaines, situé à environ 8 km au N.-O. de Chalon-sur-Saône, se développe sur 1,5 km de long selon un unique axe E-O, depuis la montagne Saint-Hilaire à l’ouest, occupée au Néolithique puis durant l’Antiquité tardive et le haut Moyen Âge, jusqu’à l’église paroissiale Saint-Just, à l’est. Malgré une emprise limitée et contrainte par de nombreux réseaux existants, l’opération a permis de documenter l’environnement immédiat de l’église, occupé depuis l’Antiquité jusqu’à nos jours.

Robust delay-dependent H∞ control of uncertain time-delay systems with mixed neutral, discrete, and distributed time-delays and Markovian switching p…

2011

Author's version of an article published in the journal: IEEE Transactions on Circuits and Systems I: Regular Papers. Also available from the publisher at: http://dx.doi.org/10.1109/tcsi.2011.2106090 The problem of robust mode-dependent delayed state feedback H ∞ control is investigated for a class of uncertain time-delay systems with Markovian switching parameters and mixed discrete, neutral, and distributed delays. Based on the LyapunovKrasovskii functional theory, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities for the stochastic stability and stabilization of the considered system using some free matrices. The desired control is …

Percorsi esistenziali del dialogo interreligioso. Scene vissute fuori campo

2016

Come pensare il dialogo tra le diverse religioni? Per rispondere a questa domanda, faccio appello a due frammenti di vita personale – l’incontro con due mormoni americani a Tartu e con un marocchino musulmano a Nîmes – per risalire all’origine del dialogo come forma di vita in divenire e alla forza del processo di consapevolizzazione che dovrebbe sussistere, nella mia ipotesi, in qualsiasi società per insegnare e apprendere a vedere l’alterità (religiosa) come un percorso di riposizionamento continuo del Sé e dell’altro. A questo fine, discuto alcune ipotesi formulate in antropologia delle religioni – più particolarmente da Evans-Pritchard per la religione nuer e da Geertz per la religione …

Isomorphism of Pitch and Time

2016

An ongoing debate regarding the perception of pitch and time is whether information on the two dimensions is processed independently or interactively. To study this, we tested whether listeners prefer sequences in which tonally stable tones coincide with rhythmically stable tones. Our study builds on a noted isomorphism between pitch intervals in the diatonic scale and tone durations in the standard rhythm originating in Ghana. This isomorphism is shown in a) the maximally even structure of 2212221 and b) the cyclic nature with seven possible starting points. To better understand pitch-time relationship, we conducted two experiments. In Experiment 1, we created seven scales based on the dia…

Lipschitz Carnot-Carathéodory Structures and their Limits

2022

AbstractIn this paper we discuss the convergence of distances associated to converging structures of Lipschitz vector fields and continuously varying norms on a smooth manifold. We prove that, under a mild controllability assumption on the limit vector-fields structure, the distances associated to equi-Lipschitz vector-fields structures that converge uniformly on compact subsets, and to norms that converge uniformly on compact subsets, converge locally uniformly to the limit Carnot-Carathéodory distance. In the case in which the limit distance is boundedly compact, we show that the convergence of the distances is uniform on compact sets. We show an example in which the limit distance is not…
