In offering a platform for cutting edge scholarship in the emerging field of digital history and hermeneutics, the series aims at making a critical intervention in the field of digital humanities and introducing key debates and concepts of digital history to the historical community at large.Studies in Digital History and Hermeneutics Digital HistoryDigital humanitiesHermeneuticsDigital humanities.Hermeneutics.001.30285Döring Karoline Dominika910165Haas Stefan1255082König Mareike1255083Wettlaufer Jörg1255084MiAaPQMiAaPQMiAaPQBOOK9910774727503321Digital History2910089UNINA05586nam 2200697Ia 450 991087775830332120200520144314.01-282-25947-497866122594700-470-74908-30-470-74909-1(CKB)1000000000794222(EBL)454286(OCoLC)441875062(SSID)ssj0000300585(PQKBManifestationID)11253358(PQKBTitleCode)TC0000300585(PQKBWorkID)10251814(PQKB)10557101(MiAaPQ)EBC454286(PPN)221408487(EXLCZ)99100000000079422220090515d2009 uy 0engur|n|---|||||txtccrIsogeometric analysis toward integration of CAD and FEA /J.
