Effects of pendent phenol functional groups on secondary coordination spheres of heme like Fe-salen complexes
No full textSince the beginning of industrial revolution, burning of fossil fuels has mainly led to increase in atmospheric concentration of CO2 , a Green House Gas (GHG), from 250 ppm to 400 ppm between 1800 and 2012. One way to reduce the burning of fossil fuels and CO2 emission rate is to explore alternative carbon free fuels to meet the energy demand.This project aims at the synthesis and study of metal complexes inspired by biological models that will help better design catalysts to perform water oxidation more effectively.This poster won the Dean, Faculty of Science award (2020).

21st-century scholarship and Wikipedia
No full textWikipedia, the world’s fifth most-used Web site, is a good illustration of the growing credibility of online resources. In his article in Ariadne earlier this year, “Wikipedia: Reflections on Use and Academic Acceptance”, Brian Whalley described the debates around accuracy and review, in the context of geology. He concluded that ‘If Wikipedia is the first port of call, as it already seems to be, for information requirement traffic, then there is a commitment to build on Open Educational Resources (OERs) of various kinds and improve their quality.’ In a similar approach to the Geological Society event that Whalley describes, Sarah Fahmy of JISC worked with Wikimedia and the British Library on a World War One (WWI) Editathon. There is a rich discourse about the way that academics relate to Wikipedia
Konzeptionelle Erweiterung bestehender Informationsmodelle für PCC Modelle in Soft Robotics
No full textInformation Model for Describing Granular Robot Module Functionalities
No full textThe automation of flexible production systems using robots is becoming increasingly important in modern manufacturing. This paper addresses the challenge of effectively managing and utilizing functionalities provided by robot modules in automated production systems. To tackle this, we propose the development of an information model, structuring robot module functionalities. By discussing and adapting existing methods, such as the Capability Skill Service (CSS) model, we aim to create a standardized and efficient way to structure and describe the functionalities of robot modules. This approach seeks to reduce engineering costs, improve system integration, and enhance operational efficiency. Ultimately, the development of this information model could lead to more advanced, simplified and flexible solutions for robotic automation
Analyse und Konzeption von Informationsmodellen für Soft Robotics
No full textModerne flexible Fertigungs- und Montagelinien werden zunehmend durch Anwendungen aus dem Bereich der Mensch-Maschine-Kooperation und -Kollaboration ergänzt. Dabei spielen Cobots unterschiedlichster Hersteller eine wesentliche Rolle und bilden den Stand der Technik. In der Forschung werden neue Roboterklassen untersucht, welche das Zusammenspiel von Mensch und Maschine inhärent sicher ermöglichen. Hierzu zählt das Konzept von Soft Robots. In diesem Beitrag stellen die Autoren ein Konzept für deren Integration in modell-basierte Engineering-Methoden vor. Hierzu werden Informationsmodelle für Rigid Body Robotik, welche aktuell die Basis für die Robotik-Modellierung bilden, auf ihre Adaptierbarkeit auf „Piece-Wise Constant Curvature“ (PCC) Modelle der Soft Robotik analysiert. Diese mathematische Modellierung soll in bekannte Informationsmodelle integriert werden. Als Grundlage dient dabei das als neutraler Standard klassifizierte Unified Robotics Description Format (URDF). Zum Abschluss werden die kritischen Elemente der Erweiterung des Informationsmodells URDF identifiziert

No full textHow Many Answers Are Enough? Optimal Number of Answers for Q&A Sites
No full textWith the proliferation of the social web, questions about information quality and optimization attract the attention of IS scholars. Question-answering (QA) sites, such as Yahoo!Answers, have the potential to produce good answers, but at the same time not all answers are good and not all QA sites are alike. When organizations design and plan for the integration of question answering services on their sites, identification of good answers and process optimization become critical. Arguing that ‘given enough answers all questions are answered successfully,’ this paper identifies the optimal number of posts that generate high quality answers. Based on content analysis of Yahoo! Answers’ informational questions (n=174) and their answers (n=1,023), the study found that seven answers per question are ‘enough’ to provide a good answer
Power Relations and Social Classes in Pengakuan Pariyem by Linus Suryadi AG: Reflection of Masculine Ideology
No full textThe study aims to explore power relations and social classes as the reflections of the masculine ideology of the author in the novel Pengakuan Pariyem by Linus Suryadi AG. The theories implemented in the study are van Dijk’s power relations and social classes theory and Connell’s masculinity theory. The study is qualitative descriptive and applies the Critical Discourse Analysis (CDA) method, used to dismantle the ideology that is produced and reproduced through the language within the novel. The research data are lingual units that indicate power relations and social classes which simultaneously reflect the notion of masculinity. The results of the study are as follows. First, Pariyem as the central character in the novel lives within a hierarchical and dualistic Javanese society. Her submission as the babu (housemaid) of a priyayi (noble) family does not only lead Pariyem to be dominated symbolically, but also legitimizes the priyayi (aristocrats) power over wong cilik (commoners). It is reinforced by the representations of the priyayis’ world views in terms of culture, aristocracy, bureaucracy, and education orientation. It shows that priyayis are culturally dominant. Secondly, since Pariyem is a character created by a male author, her behaviors and actions reflect the ideology of masculinity. Rather than voicing women, the power relations that Pariyem experiences through the events constructed in the novel show that she embodies the masculine ideology, or masculinity.
