The political irruption of short video: Is TikTok a new window for Spanish parties?

2022

This paper analyses the use of TikTok by the main Spanish parties. The article studies the intensity of use of the short video social network by the accounts of the Partido Popular, Vox, Podemos and Ciudadanos, their narratives and themes, and the views obtained based on them. The research applies a content analysis to the videos published by these groups from account creation until the end of 2020, a period in which the PSOE had no presence. The corpus amounts to 182 units of analysis. The results show that the partisan use of TikTok is still in its infancy and that its intensive use is limited to newly emerging parties, with more favourable results for the most polarised groupings.

Smart camera design for realtime High Dynamic Range imaging

2011

International audience; Many camera sensors suffer from limited dynamic range. The result is that there is a lack of clear details in displayed images and videos. This paper describes our approach to generate high dynamic range (HDR) from an image sequence while modifying exposure times for each new frame. For this purpose, we propose an FPGA-based architecture that can produce a real-time high dynamic range video from successive image acquisition. Our hardware platform is build around a standard low dynamic range CMOS sensor and a Virtex 5 FPGA board. The CMOS sensor is a EV76C560 provided by e2v. This 1.3 Megapixel device offers novel pixel integration/readout modes and embedded image pre…

Dabisko likumu simulācija un tās ietekme uz emocijām

2022

Darba “Dabisko likumu simulācija un tās ietekme uz emocijām” mērķis ir izpētīt dažādu ģeometrijas un fizikas likumu simulācijas spēlēs un to ietekmi uz cilvēka emocijām. Pētījumā ir iesaistītas netriviālās animācijas, kas izmantotas spēlēs un informatīvajos videoklipos, un pētīt lietotāju emocionālo spektru pēc to noskatīšanas. Eksperimentā pētītās simulācijas tika novērtētas pēc reālistiskuma un tika sniegti vairāki viedokļi par to pozitīviem un negatīviem aspektiem. Pētījuma rezultāti var tikt pielietojami simulāciju modelēšanas uzlabojumos dažādās digitālās vidēs.

Eksperiments metodoloģijā: Starp “Virtuālo” un “Īsto”

2018

Bakalaura darbs “Eksperiments metodoloģijā: Starp “Virtuālo” un “Īsto”” fokusējas uz video spēļu spēlētāju imersīvām pieredzēm, kuras izraisa masīvās daudzspēlētāju tiešsaistes lomu spēles World of Warcraft virtuālās pasaules vizuālās un skaņas ainavas. Es skatu virtuālu spēļu pasauli kā digitālu kultūras artefaktu, kas sastāv no vairākām mākslas formām, un es pievēršu uzmanību veidiem, kādos šīs mākslas formas var sekmēt cilvēku radošumu un imersiju, kā arī dzīves uzskatus un tās trajektoriju virzienus ārpus virtuālā lauka. Konceptualizējot virtuālās ainavas kā atmiņu piesātinātas, es atsedzu un analizēju neaizmirstamas cilvēku pieredzes dziļumu, kas tajās ir iesakņots. Eksperiments ar etn…

Implementació i avaluació de codis QR en laboratoris docents d’enginyeria química

2014

Els codis QR (Quick Response) són codis de barra àmpliament utilitzats en aplicacions comercials i de màrqueting per incloure enllaços a pàgines web, entre altres coses. En l'actualitat un gran nombre de dispositius electrònics com telèfons intel·ligents o tauletes compten amb aplicacions capaces de capturar aquesta informació, permetent al seu usuari emmagatzemar-la i compartir-la amb altres usuaris. Hi ha alguns exemples de la seva aplicació en l'educació, encara que no s'han trobat exemples en l'àrea d'Enginyeria Química. En aquest context, el treball que es presenta és la implantació i avaluació de codis QR en laboratoris docents d'Enginyeria Química amb accés a contingut docent multimè…

Time Unification on Local Binary Patterns Three Orthogonal Planes for Facial Expression Recognition

2019

International audience; Machine learning has known a tremendous growth within the last years, and lately, thanks to that, some computer vision algorithms started to access what is difficult or even impossible to perceive by the human eye. While deep learning based computer vision algorithms have made themselves more and more present in the recent years, more classical feature extraction methods, such as the ones based on Local Binary Patterns (LBP), still present a non negligible interest, especially when dealing with small datasets. Furthermore, this operator has proven to be quite useful for facial emotions and human gestures recognition in general. Micro-Expression (ME) classification is…

Audience experience of commercial videos and feature length films : are they universal or culturally mediated?

2017

Audiovisual contents constitute one of the most common ways of communicating information. However, audiovisual products are difficult to study because they integrate a lot of complex communication and artistic elements. Meaning and emotions are conveyed by combining film elements but also narrative elements, music and other audio aspects, which unfold over time and can be used to impact the audiences. Here, the user experience approach is taken to try to understand the relation between the video’s elements and the emotions produced in the audience. Emotions are understood within an appraisal framework where elements of the audiovisual format and content are integrated in memory with previou…

Distopijas atainojums videospēlē "Deus Ex: Human Revolution"

2020

Bakalaura darbā izpētīts, kā videospēle “Deus Ex: Human Revolution” konstruē distopiju, izmantojot sava medija priekšrocības – naratīvu, spēles pasauli un narativizētu saskarni. Teorētiskajā daļā aplūkota videospēļu spēja funkcionēt kā medijam, kā arī noskaidroti distopijas un kiberpanka pamatprincipi. Metodoloģijas daļā aprakstītas darbā izmantotās metodes – naratīva analīze, semiotiskā analīze, tuvlasīšana. Empīriskajā daļā, izmantojot izvēlētās pētniecības metodes, izpētīts, kā “Deus Ex: Human Revolution” autori spēj apvienot naratīvu, spēles pasauli un narativizētu saskarni, lai radītu daudzslāņainu distopijas darbu.

Producing Lecture Videos from Face-to-face Teaching

2014

There is a clear demand for lecture videos in modern education. Nevertheless, the desire to keep face-to-face education remains as well. In such a case, the natural option is to produce videos in face-to-face teaching situations rather than in a studio environment. The challenge this kind of production faces is how to make it to cover an entire degree program cost-efficiently while serving the purpose intended. This article explains the demands set for video production in the context of face-to-face education at the scale of a degree program and how to effectively respond to them in practice. The paper also evaluates the effectiveness and impacts of the production model developed in connect…
