Current modelling tools have problems with time transformations (such as a time delay) or multi-rate systems.<\/jats:p>\n          <jats:p>We will present a novel approach that implements signals as functions of time, directly corresponding to their mathematical representation. This enables an exact implementation of time transformations and as an additional advantage enables local control over time. A representation of components and signals in both domains is provided, together with composition operators to allow the specification of signal flow diagrams.<\/jats:p>","DOI":"10.1145\/2000367.2000373","type":"journal-article","created":{"date-parts":[[2011,6,28]],"date-time":"2011-06-28T17:31:10Z","timestamp":1309282270000},"page":"27-30","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["The problem with time in mixed continuous\/discrete time modelling"],"prefix":"10.1145","volume":"8","author":[{"given":"Kenneth C.","family":"Rovers","sequence":"first","affiliation":[{"name":"University of Twente, AE Enschede, The Netherlands"}]},{"given":"Jan","family":"Kuper","sequence":"additional","affiliation":[{"name":"University of Twente, AE Enschede, The Netherlands"}]},{"given":"Gerard J.
