In recent years, the messaging application has been Indonesia’s most widely used mobile app. The number of users of these instant messaging (IM) applications has also been increasing constantly. 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.
Diese Arbeit gibt einen Einblick sowie eine Einschätzung eines Code-basierten
Werkzeuges zur Datenvisualierung, der d3js bibliothek für JavaScript. 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.

Resistance spot welding is the dominant process in the present mass production of steel constructions without sealing requirements with single sheet thicknesses up to 3 mm. Two of the main applications of resistance spot welding are the automobile and the railway vehicle manufacturing industry. The majority of these connections has safety-related character and therefore they must not fall below a certain weld diameter. Since resistance spot welding has been established, this weld diameter has been usually used as the gold standard. Despite intensive efforts, there has not been found yet a reliable method to detect this connection quality non-destructively. Considerable amounts of money and steel sheets are wasted on making sure that the process does not result in faulty joints. The indication of the weld diameter by in-process monitoring in a reliable way would allow the quality documentation of joints during the welding process and additionally lead through demand-actuated milling cycles to a substantial decrease of electrode consumption. An annual, estimated reduction in the seven- to nine-figure range could be achieved. It has an important impact, because the economics of the process is essentially characterized by the electrode caps (Klages 24). We propose a simple and straightforward approach using data mining techniques to accurately predict the weld diameter from recorded data during the welding process. In this paper, we describe the methods used during data preprocessing and segmentation, feature extraction and selection, and model creation and validation. We achieve promising results during an analysis of more than 3000 classified welds using a model tree as a predictor with a success rate of 93 %. In the future, we hope to validate our model with unseen welding data and implement it in a real world application.

This paper outlines our current research program in the fields of ambient intelligence and context-aware computing and the tools we are building to accomplish this research program. From a discussion of our conception of mental models in the domain of ambient context-aware computer systems we derive hypotheses which we intend to test empirically. A modular framework for implementing and assessing situation awareness in humans and computers is introduced. We describe the framework’s architecture and illustrate its suitability for its intended purpose. Finally, we present an outline of our next steps towards real world application systems for our research.
