Ionic Liquids: media for better molecular catalysis
No full textIonic liquids (ILs) are more and more suggested as substitutes for traditional solvents in organic synthesis and catalysis. They
are suitable candidates for the dissolution of ionic complexes. They can activate and retain them in a polar state: in fact, they act as
sequestrands, opening the route to two-phase processes and easier catalyst recovery. This paper reviews authors’ results with the
development of new syntheses of ILs and applications in carbon–carbon bond formation (dimerisation of methyl acrylate) and
redistribution (ring closing metathesis) reactions using ionic precatalysts

Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Conceptualization of a real-time information processing platform for context-aware informing cyber-physical systems
No full textInforming cyber-physical systems (I-CPSs) are designed to accomplish sensing, reasoning and informing activities in dynamic context. In order tosimplify and accelerate the design and implementation process of multiple context-aware ICPSs, we are developing an information sensing,computing and actuating (SCA) platform that can be used as a central module of these systems. This paper presents the concept of a SCA platform. Thefunctionality of the platform includes development of context-dependent strategies to adapt the sensing, reasoning and informing behaviors of the platform to various dynamic contexts. There are four constituents of the platform: (1) a generic kernel, (2) built-in elements, (3) add-on components, and (4) system interfaces. The paper also discusses both the internal and external integration mechanism of the SCA platform, which can be customized according to the needs of specific I-CPS applications by extending the generic kernel with various functional built-in elements and add-on components. The feasibility andapplicability of the platform have been tested through a case study: an indoor fire evacuation guiding system. The proposed platform provides a useful package of functionalities, alleviates the burden of developers, and speeds up the development of applications specific context-aware I-CPS.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work publicCyber-Physical System
