    Beschreibung: The project DeepGreen aims to realise better usage of green open access publication rights with regard to Alliance Licenses in Germany (https://www.nationallizenzen.de/open-access). Together with publishers who offer Alliance Licenses and authorized libraries, the project group intends to develop a prototype of a nearly fully automated workflow that covers the delivery of data from the publishers, including the article full texts, as well as the process of loading data into the institutional repositories of licensees. Further information about the project can be found within ZIB-Report 15-58, urn:nbn:de:0297-zib-56799. In order to become acquainted with publishers’ processes for exchanging documents and metadata, the project group developed a questionnaire for an online survey. The publishing of this questionnaire is intended to demonstrate relevant aspects of the issue (e. g. methods of data exchange, protocols and interfaces) and to foster reuse of valuable questionnaire elements. The XML-file can be reused as a template, the PDF-file reproduces the original survey layout.

    Beschreibung: Recently the unsteady response of 1-D premixed flames to acoustic pressure waves for the range of frequencies below and above the inverse of the flame transit time was investigated experimentally by Wangher et al. using OH chemiluminescence. They compared the frequency dependence of the measured response to the prediction of an analytical model proposed by Clavin et al., derived from the standard flame model (one-step Arrhenius kinetics). Discrepancies between the experimental results and the model led to the conclusion that the standard model does not provide an adequate description of the unsteady response of real flames and that it is necessary to investigate more realistic chemical models. Here we follow exactly this suggestion and perform numerical studies of the reponse of lean methane flames using different reaction mechanisms. We find that the global flame response obtained with both detailed chemistry (GRI3.0) and a reduced multi-step model by Peters lies slightly above the predictions of the analytical model, but is close to experimental results. We additionally used an irreversible one-step reaction model which yields good results at least for frequencies close to the inverse flame transit time.

    Beschreibung: For an analysis of a molecular system from a computational statistical thermodynamics point of view, extensive molecular dynamics simulations are very inefficient. During this procedure, at lot of redundant data is generated. Whereas the algorithms spend most of the computing time for a sampling of configurations within the basins of the potential energy landscape of the molecular system, the important information about the long-time behaviour of the molecules is given by transition regions and barriers between the basins, which are sampled rarely only. Thinking of molecular dynamics trajectories, researchers try to figure out which kind of dynamical model is suitable for an efficient simulation. This article suggests to change the point of view from extensive simulation of molecular dynamics trajectories to more efficient sampling strategies of the conformation dynamics approach.
