Annual Report 2015 NTNU AMOS NTNU AMOS Centre for Autonomous Marine Operations and Systems Annual Report 2015 Annual Report OUR VISION To establish a world-leading research centre for autonomous marine operations and systems: To nourish a lively scientific heart in which fundamental knowledge is created through multidisciplinary theoretical, numerical, and experimental research within the knowledge fields of hydrodynamics, structural mechanics, guidance, navigation, and control. Cutting-edge inter-disciplinary research will provide the necessary bridge to realise high levels of autonomy for ships and ocean structures, unmanned vehicles, and marine operations and to address the challenges associated with greener and safer maritime transport, monitoring and surveillance of the coast and oceans, offshore renewable energy, and oil and gas exploration and production in deep waters and Arctic waters.

  • Nodes of Contemporary Finnish Literature
    Nodes of Contemporary Finnish Literature Edited by Leena Kirstinä Studia Fennica Litteraria The Finnish Literature Society (SKS) was founded in 1831 and has, from the very beginning, engaged in publishing operations. It nowadays publishes literature in the fields of ethnology and folkloristics, linguistics, literary research and cultural history. The first volume of the Studia Fennica series appeared in 1933. Since 1992, the series has been divided into three thematic subseries: Ethnologica, Folkloristica and Linguistica. Two additional subseries were formed in 2002, Historica and Litteraria. The subseries Anthropologica was formed in 2007. In addition to its publishing activities, the Finnish Literature Society maintains research activities and infrastructures, an archive containing folklore and literary collections, a research library and promotes Finnish literature abroad.

  • Regatul Romaniei
    RegatulRomaniei file:///C:/Programele%20Mele/IstorieRomania1/RegatulRomaniei/Regat... Regatul României Visul unirii tuturor românilor sub un singur steag a frământat mințile conducătorilor încă din cele mai vechi timpuri, dar alianțele militare și interesele de ordin comercial nu au fost în favoarea simplificării relațiilor dintre diferitele formațiuni statale. În vechime, țările românești au negociat protecția celor două mari imperii ale romanilor, apoi începând cu secolul al XIII-lea au întreținut legături de prietenie și ajutor mutual cu Polonia și Lituania. Din secolul al XV-lea, ca state vasale Imperiului Otoman dar sub protecția directă a Hanatului Crimeei, s-a pus problema formării unui eyalat turcesc comun. Proiectul a fost însă refuzat cu dârzenie, ca urmare a divergențelor de ordin religios. Ca o soluție de compromis, sultanii au permis independența religioasă a celor trei principate, în schimbul dependenței economice. Situația de criză a intervenit o dată cu revoluția și apoi războiul de independență purtat de greci și sârbi. Sub aripa ocrotitoare a Bisericii Ortodoxe Răsăritene, creștinii din toate țările Balcanice au ridicat la început glasul, apoi armele, cerând vehement ieșirea din situația de compromis religios. Ca rezultat, boierii și dragomanii greci au fost maziliți, iar mănăstirile filiale ale celor de la Muntele Athos au fost secularizate. În urma grecilor au rămas nenumăratele lor rude născute din alianțe cu casele boierești autohtone, practic aproape toată crema boierimii. Pentru a umple vidul administrativ rămas s-a hotărât instituirea unei locotenențe domnești, ajutată de o Adunare Constituantă a fruntașilor celor două țări. În ambele principate, toate sufragiile au fost întrunite în anul 1859 de Colonelul Alexandru Ioan Cuza, cu funcția de Ministru de Război, fost deputat de Galați și fost șef al Miliției de la Dunărea de Jos.
