IMS-IMS and IMS-IMS-IMS/MS for separating peptide and protein fragment ions.
Multidimensional ion mobility spectrometry (IMS-IMS and IMS-IMS-IMS) techniques have been combined with mass spectrometry (MS) and investigated as a means of generating and separating peptide and protein fragment ions. When fragments are generated inside a drift tube and then dispersed by IMS prior to MS analysis, it is possible to observe many features that are not apparent from MS analysis al...

متن کاملDelivering courses modelled using IMS Learning Design1
E-learning promises efficiency of education. This promise is based on the economics of multiple delivery, whereby initial production costs for an e-learning course are recouped by delivering the course to different groups of learners at different times. This can only be realised by distinguishing between abstract representations of courses and instances of these representations involving specif...
متن کاملIMS Security Analysis using Multi-attribute Model
IP Multimedia Subsystem (IMS) plays as a core platform in next-generation-network architecture, which advocates for an open and inter-operable service infrastructure. However, over the years, not much attention has been paid to the security problem of IMS. The time has come to now address security issues. This paper proposes a multi-attribute stereo model based on X.805 standard, which addresse...
متن کاملUsing IMS learning design to model curricula
The traditional notion of the curriculum as a fixed list of topics to be studied sequentially is under strain as pressure for flexibility in education increases. However, curriculum flexibility can lead to curriculum complexity, hindering learners in the development of their competences. This article presents a formal model for the description of curricula, designed to underpin guidance support...
