La représentation du rugby masculin et féminin : une analyse de discours chez les spectateurs
2014
Le but de l'étude présentée est d'analyser les représentations d'unsport typé masculin, le rugby, dans le discours de spectateurs à l'issuede matchs. Le champ théorique renvoie à l'école européenne desreprésentations sociales (Moscovici, 1961) et ses développements entermes de structure stabilisée (Abric, 1994). Il renvoie également auxprésupposés de l'analyse de discours selon Ghiglione (1985). Le corpusest constitué de 120 discours écrits dans les salles réservées auxsupporters ou dans les bars restaurants où ils se retrouvent après lesrencontres, la consigne étant soit de caractériser le rugby masculin soitde caractériser le rugby féminin. La méthode utilisé…

Interspecific information on predation risk affects nest site choice in a passerine bird
2018
Abstract Background Breeding site choice constitutes an important part of the species niche. Nest predation affects breeding site choice, and has been suggested to drive niche segregation and local coexistence of species. Interspecific social information use may, in turn, result in copying or rejection of heterospecific niche characteristics and thus affect realized niche overlap between species. We tested experimentally whether a migratory bird, the pied flycatcher Ficedula hypoleuca, collects information about nest predation risk from indirect cues of predators visiting nests of heterospecific birds. Furthermore, we investigated whether the migratory birds can associate such information w…
Remote Sensing of 3-D Geometry and Surface Moisture of a Peat Production Area Using Hyperspectral Frame Cameras in Visible to Short-Wave Infrared Spe…
2016
Miniaturized hyperspectral imaging sensors are becoming available to small unmanned airborne vehicle (UAV) platforms. Imaging concepts based on frame format offer an attractive alternative to conventional hyperspectral pushbroom scanners because they enable enhanced processing and interpretation potential by allowing for acquisition of the 3-D geometry of the object and multiple object views together with the hyperspectral reflectance signatures. The objective of this investigation was to study the performance of novel visible and near-infrared (VNIR) and short-wave infrared (SWIR) hyperspectral frame cameras based on a tunable Fabry–Pérot interferometer (FPI) in measuring a 3-D digital sur…
A multi-objective Pareto design approach for simultaneous control of thinning and springback in complex stamping operations.
2009
Abstract In sheet metal forming operations design, optimization problems have to be solved in order to reach optimal process conditions. In these problems, there are some crucial issues to be taken into account: - most of the problems are multi objective problems, generally characterized by conflicting objectives: the definition of proper parameters aimed to prevent both springback and fracture is a typical example of an optimization problem in sheet metal forming characterized by conflicting goals; - in an industrial environment a great interest would be focused on the availability of a cluster of possible optimal solutions instead of a single “almost optimal” solution. Taking into account…

Longbordistu subkultūra Rīgā
2018
Bakalaura darba tēma ir „Longbordistu subkultūra Rīgā”. Tēmas aktualitāte –longbordošana un longbordisti vispār līdz šīm nav pētīti, kā arī Rīgā longbords ir kļuvis populārs un aktuāls pēdējos četrus gadus. Tāpēc šī pētījuma mērķis ir izpētīt longbordistus kā subkultūru Rīgā. Pētnieciskais jautājums ir: Kādas ir longbordistu galvenās subkultūras iezīmes? Teorētiskajā daļā tiks apskatīts subkultūras jēdziens, tiks skaidrots dzīvesstila jēdziens, longbordošanas vēsturiskā attīstība, longborda braukšanas veidi, kā arī, kā longbords iekļaujas starp ekstrēmiem sporta veidiem. Bakalaura darbā izmantotas kvalitatīvās metodes. Tika veiktas intervijas – padziļinātās ar ekspertiem, daļēji strukturētā…
Insecure Firmware and Wireless Technologies as “Achilles’ Heel” in Cybersecurity of Cyber-Physical Systems
2022
In this chapter, we analyze cybersecurity weaknesses in three use-cases of real-world cyber-physical systems: transportation (aviation), remote explosives and robotic weapons (fireworks pyrotechnics), and physical security (CCTV). The digitalization, interconnection, and IoT-nature of cyber-physical systems make them attractive targets. It is crucial to ensure that such systems are protected from cyber attacks, and therefore it is equally important to study and understand their major weaknesses. peerReviewed
