This can be achieved by a high amount of content generated by procedural generation. Space themed games in particular usually lack game worlds with visual and gameplay diversity. This work focuses on the generation of diverse planets as game worlds for an interplanetary building strategy PC game. Therefore, a generator was developed within the Unity game engine to generate pseudo random planet models. Classic and modern approaches to procedural content generation were evaluated and compared in order to assess their suitability for the implementation of the generator. The generated models utilize a data structure that allows for changes in the model based on player interaction. The resulting planets differ in size, biomes and surface structure. The planet's basic sphere geometry is derived from a subdivided icosphere. Using a voronoi diagram, its surface is divided into regions representing biomes, continents and oceans. A basic simulation of continental plates is used to determine mountain and canyon locations. These are formed by nested noise functions and domain warping creating a height field. The planet surface consists of multiple material layers represented by data.}, language = {de} } @misc{Ney2022, type = {Master Thesis}, author = {Ney, Audrey}, title = {E-Learning an der Technischen Hochschule Brandenburg - Bereitstellung eines hochschulweiten Weiterbildungsangebotes zu Themen der Informationskompetenz}, doi = {10.25933/opus4-2871}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-28711}, school = {Technische Hochschule Brandenburg}, pages = {164}, year = {2022}, abstract = {Die vorliegende Arbeit besch{\"a}ftigt sich mit der Frage, wie ein E-Learning-Angebot an der Technischen Hochschule Brandenburg das Interesse am Thema der Informationskompetenz steigern sowie diese Kompetenzen entsprechend vermitteln kann.

The forecast of the market share of new BEV car registrations in Germany can help efficiently evaluate strategic and future-oriented decisions, e.g., the climate targets set by the federal government. Machine learning methods were used to implement forecasting. Two machine learning models were used to forecast of the market share of new BEV car registrations in Germany: SARIMA(X) and DeepAR model. Due to variety in input datasets, four univariate and multivariate time series analysis models were trained. Afterwards, all four trained models were compared with each other using the RMSE metric. The last six months of the dataset were used to evaluate the model quality. The result of model comparison shows that SARIMAX model needs the exogenous variables to create a forecast of the multivariate data sets. However, the DeepAR model does not require any exogenous variables to generate forecast. Furthermore, if the input dataset contains at least 300 observations, then the implementation of DeepAR model is much more advantageous than SARIMA(X) model. DeepAR model not only supports the univariate and multivariate datasets, but also creates a global model that generates a forecast per variable. This is a great advantage over the SARIMA(X) model, which is not capable of this.}, language = {de} } @masterthesis{Rothenhaeusler2022, type = {Bachelor Thesis}, author = {Rothenh{\"a}usler, Luis}, title = {d3.js and its potential in data visualization}, doi = {10.25933/opus4-2853}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-28536}, school = {Technische Hochschule Brandenburg}, year = {2022}, abstract = {Diese Arbeit gibt einen Einblick sowie eine Einsch{\"a}tzung eines Code-basierten Werkzeuges zur Datenvisualierung, der d3js bibliothek f{\"u}r JavaScript.

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.

To interact with the digital world, we use gestures (most common: swipe gestures), voice, facial expressions and mental commands. The latter has become more important by recent press releases about scientific achievements, for example, from Neuralink [1] using invasive technology to control a computer game by thoughts only [2]. Another study says an application can display text on a screen by just thinking about a word [3]. Currently, BCIs are mainly developed for neurotechnology and healthcare. However, it is a question of time when these services will be available for commercial products for everyday life. (Until then, manufacturers have to minimize health risks and face privacy and safety regulations.) The thesis is that in the future, you will be able to interact with your digital devices just by using your thoughts and you'll do much faster. This makes sense in many situations where you f. e. do not have a free hand (manufacturing, sports) or cannot speak (underwater). But for such services, you cannot rely on conventional visual design guidelines or interaction patterns, frameworks or libraries. Navigation interacting with a digital service by mental command has a lot of advantages, the human brain comes naturally with some specific features that force us to find a radically new way to interact with digital interfaces. The following study introduces you first into working conditions with mental commands, comparing invasive and non-invasive technologies, and later on comparing several possibilities of interaction patterns for a BCI of everyday usage.

Precisely, the adaptation of AI-based resilient defenses must be driven forward. Therefore, the aim of this paper is to identify and evaluate AI-related use cases with a high impact potential on the cyber security level, while being applicable to SMEs at the same time. In order to reach the research goal, an extensive literature review of several online catalogs, surveys and online platforms was conducted. In conclusion, seven crucial AI-based security features were outlined that are providing a high impact potential to the security level for SMEs.
