Nuorten ateriarytmi : Kuka syö koulupäivinä säännöllisesti?
2006
Tutkimuksessa selvitettiin aamiaisen, lounaan ja ilta-aterian muodostaman ateriarytmin yleisyyttä 7- ja 9-luokkalaisilla suomalaisnuorilla koulupäivinä. Lisäksi tarkasteltiin elintapojen, koulutusorientaation ja perhetekijöitten yhteyksiä ateriarytmin säännöllisyyteen. Tulokset perustuvat WHO-Koululaistutkimuksen kyselyyn, johon koululaiset (N = 3477) vastasivat vuonna 2002. Aineiston analysoinnissa käytettiin ristiintaulukointeja ja logistisia regressioanalyysejä. Noin 40 prosenttia pojista ja vajaa 30 prosenttia tytöistä söi aamiaisen, lounaan ja ilta-aterian säännöllisesti koulupäivinään. Vähäinen alkoholin käyttö ja aikomus mennä lukioon olivat yhteydessä säännölliseen ateriarytmiin sek…

Šī pētījuma mērķis ir izpētīt jaunu, ar Covid-19 pandēmiju saistītu, šķirkļa vārdu iekļaušanu tiešsaistes angļu valodas vārdnīcās, kā arī noteikt un analizēt to veidus, vārdu šķiras, stilistisko raksturojumu, nozīmi un pielietotos vārddarināšanas paņēmienus. Mērķa sasniegšanai ir veikts literatūras pārskats, kā arī, empīriskajā daļā, tiek izmantotas gan kvalitatīvās, gan kvantitatīvās pētījumu metodes. Pētījuma rezultāti liecina, ka visi pētītie šķirkļa vārdi, iepriekš tika bieži lietoti angļu valodas korpusā, pirms tos ieviesa tiešsaistes vārdnīcās; vairums, bija jauni šķirkļa vārdi, kas radīti, izmantojot salikteņu veidošanu, vārdu atvasināšanu un saīsinājumu, kas pārstāv gan literārās, g…

Optical flow estimation from multichannel spherical image decomposition
2011
International audience; The problem of optical flow estimation is largely discussed in computer vision domain for perspective images. It was also proven that, in terms of optical flow analysis from these images, we have difficulty distinguishing between some motion fields obtained with little camera motion. The omnidirectional cameras provided images with large filed of view. These images contain global information about motion and allow to remove the ambiguity present in perspective case. Nevertheless, these images contain significant radial distortions that is necessary to take into account when treating these images to estimate the motion. In this paper, we shall describe new way to comp…
On Prefix Normal Words
2011
We present a new class of binary words: the prefix normal words. They are defined by the property that for any given length $k$, no factor of length $k$ has more $a$'s than the prefix of the same length. These words arise in the context of indexing for jumbled pattern matching (a.k.a. permutation matching or Parikh vector matching), where the aim is to decide whether a string has a factor with a given multiplicity of characters, i.e., with a given Parikh vector. Using prefix normal words, we give the first non-trivial characterization of binary words having the same set of Parikh vectors of factors. We prove that the language of prefix normal words is not context-free and is strictly contai…
Active lighting applied to three-dimensional reconstruction of specular metallic surfaces by polarization imaging
2006
International audience; In the field of industrial vision, the three-dimensional inspection of highly reflective metallic objects is still a delicate task. We deal with a new automated three-dimensional inspection system based on polarization analysis. We first present an extension of the shape-from-polarization method for dielectric surfaces to metallic surfaces. Then, we describe what we believe to be a new way of solving the ambiguity concerning the normal orientation with an active lighting system. Finally, applications to shape-defect detection are discussed, and the efficiency of the system to discriminate defects on specular metallic objects made by stamping and polishing is presente…
Cultura figurativa popolare. Suoi usi e riusi
2021
Il saggio, dopo una ricognizione della riflessione sulla nozione di arte popolare in ambito demoetnoantropologico, con particolare riferimento all'orizzonte figurativo in Sicilia, su sofferma su alcuni esempi della produzione contemporanea di oggetti che hanno assunto figurazioni proprie del repertorio della pittura del carro e come questo comporti un ripensamento del rapporto "langue"/"parole" del fare artistico popolare che diventa un "brand". The essay, after a survey of the reflection on the notion of popular art in the demo-ethno-anthropological field, with particular reference to the figurative horizon in Sicily, focuses on some examples of the contemporary production of objects that …
Ceramic Production in the Indigenous Settlement of Entella (Western Sicily) During the Archaic Age
2010
Indigenous fine tablewares (both plain and with painted geometric patterns/decorations) were widely diffused in western and central Sicily between the seventh and the fifth centuries BC (Gargini 1995; Spatafora 1996; Trombi 1999; Campisi 2003 However, the considerable recurrence of shapes and decorative subjects inhibits the identification of specific production centres merely on the basis of stylistic and morphological analyses. Therefore, the extent of the distribution of objects manufactured in different workshops cannot be fully appreciated, and the network of ceramic trade in Archaic Sicily is acknowledged only in terms of the relationships between the Phoenician and Greek colonies and…
Diversity of Isomerization Patterns and Protolytic Forms in Aminocarbene PdII and PtII Complexes Formed upon Addition of N,N′-Diphenylguanidine to Me…
2017
Reaction of the palladium(II) and platinum(II) isocyanide complexes cis-[MCl2(CNR)2] [M = Pd, R = C6H3(2,6-Me2) (Xyl), 2-Cl-6-MeC6H3, cyclohexyl (Cy), t-Bu, C(Me)2CH2(Me)3 (1,1,3,3-tetramethylbuth-1-yl abbreviated as tmbu); M = Pt, R = Xyl, 2-Cl-6-MeC6H3, Cy, t-Bu, and tmbu] with N,N′-diphenylguanidine (DPG) leads to DPG-derived metal-bound deprotonated acyclic diaminocarbene (ADC) species. This reaction occurs via a two-step process, involving the initial coupling of the guanidine with one of the isocyanides and leading to deprotonated monocarbene monochelated species, while the next addition grants the deprotonated bis-carbene bis-chelated metal compounds. DPG behaves as nucleophile, depr…
