Acoustic wave guides as infinite-dimensional dynamical systems

2015

We prove the unique solvability, passivity/conservativity and some regularity results of two mathematical models for acoustic wave propagation in curved, variable diameter tubular structures of finite length. The first of the models is the generalised Webster's model that includes dissipation and curvature of the 1D waveguide. The second model is the scattering passive, boundary controlled wave equation on 3D waveguides. The two models are treated in an unified fashion so that the results on the wave equation reduce to the corresponding results of approximating Webster's model at the limit of vanishing waveguide intersection.

Lake size and fish diversity determine resource use and trophic position of a top predator in high-latitude lakes

2015

Prey preference of top predators and energy flow across habitat boundaries are of fundamental importance for structure and function of aquatic and terrestrial ecosystems, as they may have strong effects on production, species diversity, and food-web stability. In lakes, littoral and pelagic food-web compartments are typically coupled and controlled by generalist fish top predators. However, the extent and determinants of such coupling remains a topical area of ecological research and is largely unknown in oligotrophic high-latitude lakes. We analyzed food-web structure and resource use by a generalist top predator, the Arctic charr Salvelinus alpinus (L.), in 17 oligotrophic subarctic lakes…

Dinamisku tīmekļa risinājumu izstrāde Ruby on Rails ietvarā, izmantojot WebSocket tehnoloģiju

2020

Bakalaura darba ietvaros tika apskatīta WebSocket protokola implementācija, kas ir pamatā dinamiskās tīmekļa sistēmās Ruby on Rails ietvarā – ietvarā iebūvētais Action Cable, un kopienas veidotais AnyCable, kas ir Action Cable papildinājums. Bibliotēka AnyCable piedāvā iespēju kā WebSocket serveri izmantot kādu jau no implementētajiem variantiem vai izmantot citu ar AnyCable savietojamu WebSocket serveri, kas var būt arī paša veidots. Bakalaura darba rezultātā tika izstrādāta ar AnyCable savietojama WebSocket servera programmatūra Rust programmēšanas valodā, kas ir konkurētspējīga pašreiz pieejamajiem Ruby on Rails savietojamiem WebSocket tehnoloģijas risinājumiem, etalonuzdevumos uzrādot l…

The promotion of tourism in Italian regions from a sensorial perspective: a website content analysis

2022

Recent tourism literature has identified the sensory dimension as key to understanding, planning and marketing tourist experiences. This paper aims to understand to what extent Italian regions consider the sensorial perspective in tourist communication, focusing the analysis on their institutional websites. We used the content analysis method considering two different periods to investigate the evolution of Italian tourism promotion. The results show that for all institutional websites, over time, attention engages only some of the five sensorial dimensions. That is, the communication does not appear balanced. Furthermore, the promotional communication in several regions is more oriented to…

Benthic foodweb structure in a large shallow lake studied by stable isotope analysis

2014

The benthic foodweb structure of Lake Võrtsjärv, a large (270 km2), shallow, and turbid Estonian lake, was evaluated based on C and N stable-isotope signatures (δ13C, δ15N). Variation in δ13C between sampling sites was not related to site proximity to the littoral zone or the more vegetated southern part of the lake, but rather appeared to be influenced by in-situ site peculiarities. δ13C was stable temporally and between functional feeding groups, a result implying that the whole benthic food web of the lake relies largely on the same C source admixture, essentially particulate organic matter (POM). Thus, the foodweb composition of Lake Võrtsjärv is remarkably homogeneous given the lake’s …

Travelling to the green island full of shamrocks and pubs – or not : representations of Ireland in tourism web sites

2009

 Matkailu on merkittävä tekijä elinkeinoelämässä, myös Irlannissa: kaikkiaan 5 % irlantilaisista työskenteli vuonna 2007 matkailualalla. Internet on yhä enenevässä määrin matkailun edistämiseen käytetty väylä. Matkailun kieli on oma diskurssinsa, jossa luodaan tietty kuva kohdemaasta ja sen kulttuurista. Matkailua edistävissä esitteissä, oppaissa ja WWW-sivuilla korostetaan tiettyjä asioita kun taas toiset asiat jätetään mainitsematta. Yleinen mainontastrategia on esittää kohdemaa mahdollisimman eksoottisena ja erilaisena kuin potentiaalisen asiakkaan oma kotimaa, jolloin korostetaan kohdemaan erikoisempia piirteitä. Kohteeseen liittyvien stereotypioiden hyödyntäminen on myös yleistä matkai…

The rhetorical construction of Hillary Rodham Clinton as a presidential contender in 2016: A case study of hillaryclinton.com

2016

Niniejsze studium poświęcone jest retorycznym sposobom konstruowania obrazu kandydatki na prezydenta USA Hillary Rodham Clinton podczas pierwszej fazy kampanii 2016 roku. Kontekstem studium jest literatura na temat różnic genderowych w dyskursie politycznym, a w szczególności badania poświęcone medialnym reprezentacjom kobiet w polityce, z których wynika, że kobiety, przynajmniej w USA, muszą bardziej aktywnie niż mężczyźni kreować swój publiczny wizerunek. Za pomocą perspektywy retorycznej, zbadano strategiczny sposób konstruowania i kontrolowania publicznego obrazowania Hillary Clinton w reakcji na przedstawienia jej kandydatury przez media głównego nurtu. Analizie poddano materiały tekst…
