Therefore, real data from a secondary steel production company is used in combination with state-of-the art low carbon energy supply technologies. Also, the use of waste heat from a pusher furnace for process integration is considered. The developed temporal process model allows holistic optimizing and expanding the steel making process system regarding techno-economic criteria. As we show, implementing the annual heat demand of a municipality shows that a nearly 100 % self-sufficient heat supply is possible.

In this work, a numerical simulation model of air gasification of rice husks is developed using the Aspen Plus to investigate the feasibility of producing hydrogen-rich syngas. The model is experimentally validated with rice husk gasification results and other published studies. The influence of temperature and equivalence ratio on the syngas composition, H2 yield, LHVSyngas, H2/CO ratio, CGE, and PCG was studied. Furthermore, the synchronized effects of temperature and ER are studied using RSM to determine the operational point of maximizing H2 yield and PCG. The RSM analysis results show optimum performance at temperatures between 820 °C and 1090 °C and ER in the range of 0.06–0.10. The findings show that optimal operating conditions of the gasification system can be achieved at a more refined precision through simulations coupled with advanced optimization techniques.

The question type STACK in the Moodle learning management system combined with the interactive graphics library JSXGraph has a great potential for implementation of e-learning resources addressing these skills in formative and summative settings. The authoring process of such materials is complex due to multiple markup and programming languages like HTML, LaTeX, Maxima and JavaScript (JS) being involved. The Meclib concept mitigates this complexity and allows for efficient bulk production of material with consistent appearance and user experience. The core of Meclib is a set of pre-defined JSXGraph-based objects with an interface to Maxima, such that no problem specific JS code is required at all. The present paper outlines the basic ideas of the implementation and demonstrates the approach for some typical examples of different complexity. The focus is on applications in engineering mechanics, starting from static illustrations up to an editor for free body diagrams, with rich adaptive formative feedback.

Es werden nicht nur das Potential, sondern auch die Vor- und Nachteile evaluiert. Weiterhin wird eine Einschätzung gegeben, wann der Einsatz dieses Werkzeuges sinnvoll ist. Um diese Einschätzungen treffen zu können, werden einige Di- agramme, bezüglich der aktuellen Flüchtlichgssituation, die aufgrund des bewaffneten Ukrainekonfilktes besteht, erstellt. Dafür werden zunächst die nötigen Grundlagen erklärt. Dies umfasst sowohl Daten und Datentypen, als auch Diagramme und deren Aufbau. Abschließend werden die erstellten Diagramme, sowie d3js im Diskussionsteil ausgewertet. Da d3js in reinem JavaScript implementiert ist, lässt es sich problem- los mit anderen Frameworks kombinieren. Der Fokus von d3js liegt auf der schnellen und einfachen Manipulation von Elementen im Document Object Model. d3js ist jedoch kein Werkzeug, mit dem in wenigen Zeilen Quell- code ganze Diagramme erstellt werden können. Vielmehr müssen sowohl die einzelnen Elemente eines Diagrammes, wie auch deren Position und Ausse- hen händisch definiert werden. Das ermöglicht ein Höchstmaß an Kontrolle über das Aussehen und Verhalten der Diagramme. Es ist jedoch auch zeitin- tensiv und führt eventuell zur Implementation unübersichtlicher Diagramme. Gepaart mit der hohen initialen Lernkurve kann die Nutzung von d3js nur in speziellen Fällen, welche die volle Kontrolle über Aussehen und Verhalten von Diagrammen benötigen, empfohlen werden.

To demonstrate this principle, we experimentally investigate the enhancement of the Raman signal collected by a single dielectric microsphere, with a radius much larger than the exciting laser spot size, residing on the sample surface. The absolute microsphere-assisted Raman signal from a single graphene layer measured in air is more than a factor of two higher than that obtained with a high numerical aperture objective. Results from Mie’s theory are used to benchmark numerical simulations and an analytical model to describe the isolated microsphere focusing properties. The analytical model and the numerical simulations justify the Raman signal enhancement measured in the microsphere-assisted Raman spectroscopy experiments.

Unfortunately, research has mentioned that older users often face challenges in using them. Although some papers have created guidelines for designing interfaces for the elderly, these applications are still focused on developing according to the need of young people. In addition, the aging of adults increases their chances of facing some difficulties. Therefore, this thesis aims to give a better understanding of the interface of the mobile instant messaging (MIM) application preferred by its users, specifically Indonesian users. By distributing an online-based survey to 150 Indonesian users of the MIM application, the preferences of several features in the message list and messaging interface of this application are collected. Then, the statistical analysis of the results found that the preferences of both users’ age groups differ. Among them are the button or icon each age group finds more suitable, the bottom bar in the messaging interface, and the placement of action options to be performed to the message they prefer most. Thus, this research also presents design recommendations that both younger and older users prefer.

The crystal structure of the obtained composite samples, the porosity and the microhardness were studied by the X-ray diffraction, the electron microscopy, the weight method, and the Vickers method. Electrical characteristics (dielectric permittivity, tunability and losses) of as-prepared and annealed in oxygen medium samples were investigated at microwaves. According to structural analysis, the synthesized samples are a mixture of KFeSi glass, ferroelectric BaTiO3, and dielectric barium polytitanates; the ratio of the latter determines the electrical properties of the composites. Depending on the content of barium titanate, the studied composite samples show a permittivity from 50 to 270 with a dielectric loss level of 0,1–0,02 in frequency range from 3 to 10 GHz. Annealing of composite samples in an oxygen-containing environment leads to an increase in their dielectric permittivity and tunability by 10–25% and a twofold decrease in dielectric loss.

Excess wind constitutes roughly 40% of unused capacities of installed wind power in Germany. Using LP modelling and representative annual load profiles on an hourly resolution, we investigate the impact of the price level for wind peak power supply of residential quarters with heat, cold and electricity in Germany in combination with different power ratios of wind supply and demand. As we show, an application of wind peak tariff is technically and economically feasible and allows using green leftover energy without going in competition with e.g., green fuels or green H2 production.
