Game laboratory studies

Prof. Dr. Jens Schröter ist Herausgeber der Reihe und die Herausgeber der einzelnen Hefte sind renommierte Wissenschaftler und -innen aus dem In- und Ausland.Um die Analyse von Computerspielen aus produktionsästhetischer Perspektive zu erproben, lehnt sich der vorliegende Band an die Akteur-Netzwerk-Theorie (ANT) an. Mit ihr geht es ihm um die Frage nach den Aktanten des Game Design – etwa: Welche Hard- und Softwarekomponenten kommen wann und wofür zum Einsatz; wie und mittels welcher Medien notieren Level-Designer ihre Ideen, und wie werden die Aufzeichnungen später von Programmierern implementiert; und welche Rolle spielt eigentlich eine Action-Figur auf dem Schreibtisch eines Textur-Artists

Adaptive modeling in the frequency and time domain of high-power lithium titanate oxide cells in battery management systems

Lithium-ion batteries play a major role for the reliability and safety of the energy supply in vehicle powernetworks. Battery management systems (BMS) are needed to monitor the battery’s inner states, such as state ofcharge or state of available power. State-of-the-art algorithms running on a BMS cannot fulfill all today’s requirementscompletely such as qualification for an automotive safety integrity level, implementation on low-costhardware, adaption to different kinds of aging effects and minimized excitation in a vehicle’s power network. Inthis paper a new approach for online parameter estimation of a battery model for a lithium-ion battery withtitanate oxide anode is presented. The approach combines simple mathematical equations and low memoryconsumption while still adapting dynamically to different aging effects. In order to handle different types ofexcitation in the power network, three methods are suggested for analyzing the battery behavior in the time andfrequency domain. The algorithms are validated utilizing real driving profiles applied to aged batteries.Therefore, calendric and cyclic battery aging tests were carried out for about two years and up to 100,000equivalent full cycles. The frequency-based methods are advantageous in terms of impedance parameter trackingwhile the methods using time-domain parameterization data benefit in terms of time predictions. All proposedmethods show promising results regarding voltage predictions independent of the battery’s state of health

A plea for the integration of Green Toxicology in sustainable bioeconomy strategies - Biosurfactants and microgel-based pesticide release systems as examples

A key aspect of the transformation of the economic sector towards a sustainable bioeconomy is the development of environmentally friendly alternatives for hitherto used chemicals, which have negative impacts on environmental health. However, the implementation of an ecotoxicological hazard assessment at early steps of product development to elaborate the most promising candidates of lowest harm is scarce in industry practice. The present article introduces the interdisciplinary proof-of-concept project GreenToxiConomy, which shows the successful application of a Green Toxicology strategy for biosurfactants and a novel microgel-based pesticide release system. Both groups are promising candidates for industrial and agricultural applications and the ecotoxicological characterization is yet missing important information. An iterative substance- and application-oriented bioassay battery for acute and mechanism-specific toxicity within aquatic and terrestrial model species is introduced for both potentially hazardous materials getting into contact with humans and ending up in the environment. By applying in silico QSAR-based models on genotoxicity, endocrine disruption, skin sensitization and acute toxicity to algae, daphnids and fish, individual biosurfactants resulted in deviating toxicity, suggesting a pre-ranking of the compounds. Experimental toxicity assessment will further complement the predicted toxicity to elaborate the most promising candidates in an efficient pre-screening of new substances
