This thesis explores a 3D object detection and pose estimation approach based on the point pair features method presented by Drost et. al. [Dro+10]. While pose estimation methods have shown good improvements, they still remain a crucial problem on the computer vision field. In this work, we implemented a program that takes point cloud scenes as input and returns the detected object with their estimated pose. The program fully covers an object detection pipeline by processing 3D models during an offline phase, extracting their point pair features and creating a global descriptor out of them. During an online phase, the same features are extracted from a point cloud scene and are matched to the model features. After the voting scheme, potential poses of the object are retrieved. The poses end being clustered together and post-processed to finally deliver a result. The program was tested using simulated and real data. We evaluate these tests and present the final results, by discussing the achieved accuracy of the detections and the estimated poses.
This thesis deals with the question of which success factors apply to social media marketing. German start-up companies are examined for this purpose. The investigation is based on ten semi-structured expert interviews, which are evaluated using a qualitative content analysis. The results show that there are many success factors and that companies proceed differently in many areas when implementing social media marketing measures. Important success factors are a tailor-made, company-specific social media strategy with a clear formulation of goals, integration of social media marketing into the corporate strategy, openness to new social media trends, credibility and reputation, compliance with data protection, the correct handling of criticism, use of social media as a market research tool and a long-term social media strategy. However, the significance of the results should not be overestimated, since this is a qualitative study with a limited range and only examines individual cases. Further research on the success factors could be based on quantitative studies or group discussions in which experts or users or customers are interviewed. Another possibility is the qualitative examination of the user-generated content.
Künstliche Intelligenz (KI) hat sich in den letzten Jahren in der Gesellschaft stark ver-breitet und auch in Unternehmen einen zunehmenden Einsatz gefunden. Bekannt für den Einsatz sind meistens große internationale Konzerne, welche eine führende Position in den Märkten einnehmen. Um Deutschland als KI-Standort zu stärken, hat deshalb die Bundesregierung 2018 beschlossen, mit 5 Milliarden Euro deutsche Unternehmen in der Verwendung von KI zu fördern. Stand September 2021 wurden von diesen allerdings nur 346 Millionen abgerufen, wodurch sich die Frage stellt, wie besonders kleine und mittlere Unternehmen (KMUs) in Deutschland mit dem Thema KI umgehen.
Ziel dieser Arbeit ist es deshalb, die Perspektive der KMUs auf Akzeptanzkriterien, Hindernisse und Potenziale des Einsatzes von KI zu untersuchen. Um die Forschungs-fragen zu beantworten, wurde eine qualitative Interviewstudie mit fünf KMUs durchge-führt, welche im Anschluss mit dem Ansatz der qualitativen Inhaltsanalyse nach May-ring ausgewertet wurde.
Die Arbeit zeigt, dass Unternehmen ein großes Interesse am Thema KI haben und sich der Einsatz immer weiter verbreitet. KMUs sehen viel Potenzial durch den Einsatz der neuen Technologie, sehen aber noch einige Hindernisse, die es zu überwinden gilt.
Usability experts conduct user studies to identify existing usability problems. An established method is to record gaze behavior with an eye-tracker. These studies require a lot of effort to evaluate the results. Automated recognition of good and bad usability in recorded user data can support usability experts in eye tracking evaluation and reduce the effort. The objective of that bachelor thesis is to identify suitable eye-tracking metrics that correlate with the quality of usability. For this purpose, the central research question is answered: Which eye-tracking metrics correlate with the quality of a web form’s operation? To answer the research question, a quantitative A/B-user-study with eye-tracking was conducted and recorded the
gaze behavior of 30 subjects while filling out the web form. The web form was designed, that each web form page was available as a good and bad variant according to known usability guidelines. The results confirm a significant correlation between the eye-tracking-metric "number of visits to an
AOI" and the quality of the operation of a web form. The eye-tracking-metrics
"number of fixations within an AOI" and "duration of fixations within an AOI" also correlate with the quality of usability. No correlation could be confirmed for the "time of the first fixation within an AOI".
In der Computergrafik stellte die Berechnung von Reflexionen lange ein
Problem dar. Doch mit der ständigen Weiterentwicklung der Hardware
und Vorstellung neuer Verfahren ist eine realitätsnahe,
echtzeitfähige(durchschnittlich 60 FPS) Berechnung von Reflexionen möglich. In der folgenden Ausarbeitung werden verschiedene Reflexionsverfahren vorgestellt. Alle mathematischen und physikalischen Grundlagen werden gegeben, um die Algorithmen nachvollziehen zu können. Da eine Reflexion immer das Abtasten eines reflektierten Vektors bedeutet, werden zwei verschiedene Abtastungsverfahren für blickabhängige Reflexionen vorgestellt und anschließend implementiert. Zuletzt werden die Verfahren auf Basis von Qualität und Performance gegenübergestellt.
Digital Transformation is a main enabler for technological change in today’s society and corporate structures. Companies of all sizes have to face up the change. The com-plexity of the innovations is constantly growing. More and more information and knowledge are needed to build a basis for renewal. Different capabilities, such as highly qualified employees, material resources and the correct handling with these information, constitute the background for the advancement. Compared to large companies, small and medium sized companies (SMEs) are struggling more with these circum-stances. This leaves potential capabilities to optimize daily routines unused.
Challenges here are different internal and external barriers. Examples for that are the lack of IT expertise and innovation culture. Hence it is very important, to show SMEs the advantages of the innovation process within the scope of digital transformation. Cost savings, improvement of IT infrastructure or optimization of their business processes, are drivers that should be adopted in the awareness of SMEs.
Recommendations for action are needed, also with the support of information management. This includes information management, strategic management for external an internal information and the selection of an appropriate IT infrastructure. However dynamic management skills and sufficient IT expertise also complement the digitization process.
This becomes clear from the literature analysis following the principles of Webster and Watson (2002). The Concept mapping and the concept matrix serves to support the process. They are presenting the key words and showing the most important works of the bachelor thesis. The argumentation of the bachelor thesis based on this.
In dieser Arbeit wird die Konzeption, Implementierung und Evaluierung einer Augmented Reality-App beschrieben. Diese wurde mit dem Ziel entwickelt, Objekte im realen Raum mit virtuellen Hilfsmitteln auszumessen, sodass diese Anwendung einen Holzgliedermaßstab ersetzen kann. Hinzu kommt die praktische Speicherung der Messwerte. Angefertigt wurde die App mit der Unity Engine und programmiert in C#.
Schwerpunkte dieser Arbeit sind die Benutzerfreundlichkeit der App, sowie die Eignung von AR Foundation für das Ausmessungstool.
Die Anwendung wird auf die genannten Kriterien im Rahmen eines Nutzertests in einer abschließenden Evaluation bewertet.
Als Ergebnis ließ sich festhalten, dass sich die AR-App noch im Prototyp-Stadium befindet, aber im Allgemeinen schon als benutzerfreundlich gilt. Kleinere Änderungen sollen und müssen noch vorgenommen werden, um auch den Umgang mit dem AR-Tool zu vereinfachen.
Social media platforms such as Twitter or Reddit allow users almost unrestricted access to publish their opinions on recent events or discuss trending topics. While the majority of users approach these platforms innocently, some groups have set their mind on spreading misinformation and influencing or manipulating public opinion. These groups disguise as native users from various countries to spread frequently manufactured articles, strong polarizing opinions in the political spectrum and possibly become providers of hate-speech or extremely political positions. This thesis aims to implement an AutoML pipeline for identifying second language speakers from English social media texts. We investigate style differences of text in different topics and across the platforms Reddit and Twitter, and analyse linguistic features. We employ feature-based models with datasets from Reddit, which include mostly English conversation from European users, and Twitter, which was newly created by collecting English tweets from selected trending topics in different countries. The pipeline classifies language family, native language and origin (Native or non-Native English speakers) of a given textual input. We evaluate the resulting classifications by comparing prediction accuracy, precision and F1 scores of our classification pipeline to traditional machine learning processes. Lastly, we compare the results from each dataset and find differences in language use for topics and platforms. We obtained high prediction accuracy for all categories on the Twitter dataset and observed high variance in features such as average text length especially for Balto-Slavic countries.
Regarding the rising amount of legal regulations, businesses should get the opportunity to use software to fulfill their Compliance Management with the usage of compliance pattern. These patterns are used to represent substantive and structural parts of the processes. This means companies can increase their efficiency and react to new regulations quickly to avoid possible violation which can lead to monetary losses or legal consequences. In the literature are many approaches that deal with compliance pattern but currently there does not exist any list with necessary compliance pattern that companies should face at (Delfmann and Hübers, 2015). The following bachelor thesis classifies 80 research contributions regarding their different approaches of compliance pattern. For that a systematic literature review was executed. As a result, the author developed a graphical classification context that provides an overview of connections between different compliance approaches. Furthermore, an appendix with 32 compliance patterns of the analyzed papers was developed that contains real-world patterns with the classification of the previous sections.
Molecular dynamics (MD) as a field of molecular modelling has great potential to revolutionize our knowledge and understanding of complex macromolecular structures. Its field of application is huge, reaching from computational chemistry and biology over material sciences to computer-aided drug design. This thesis on one hand provides insights into the underlying physical concepts of molecular dynamics simulations and how they are applied in the MD algorithm, and also briefly illustrates different approaches, as for instance the molecular mechanics and molecular quantum mechanics approaches.
On the other hand an own all-atom MD algorithm is implemented utilizing and simplifying a version of the molecular mechanics based AMBER force field published by \big[\cite{cornell1995second}\big]. This simulation algorithm is then used to show by the example of oxytocin how individual energy terms of a force field function. As a result it has been observed, that applying the bond stretch forces alone caused the molecule to be compacted first in certain regions and then as a whole, and that with adding more energy terms the molecule got to move with increasing flexibility.
In dieser Arbeit wird das Echtzeitrendering von Wolken von der Theorie bis hin zur Entwicklung derselben behandelt. Dabei sollen die visuellen Eigenschaften der Wolken sowie die unterschiedliche Wolkentypen simuliert werden. Dabei ist die Berechnung der Beleuchtung essentiell für ein glaubwürdiges Ergebnis. Die Rendertechniken nutzen dabei unterschiedliche Noise-Texturen; für die Modulierung der Wolken sind es hauptsächlich Perlin- und Perlin-Worley-Texturen. Das Rendern der Wolken wird per Compute-Shader durchgeführt um die Echtzeitfähigkeit zu gewährleisten. Um die Performance zu steigern, werden Temporal Reprojektion und andere Optimierungstechniken angewendet.
In dieser Arbeit wird überprüft, ob die Befahrung mit Forstmaschinen auf Andosol-Waldstandorten Auswirkungen auf die Bodenverdichtung hat. Dazu werden Faktoren wie die Anzahl der Befahrungen, die Neigung sowie die Bodenart betrachtet und analysiert. Die Andosolböden im Untersuchungsgebiet sind durch sehr geringe Lagerungsdichten sowie hohe Porenvolumen, bedingt durch Laacher See-Tephra (LST), gekennzeichnet.
Infolge der Befahrung durch Forstmaschinen bei zum Teil ungünstiger Witterung, bildeten sich bis zu 67 cm tiefe Fahrspuren. Des Weiteren erhöht sich die Lagerungsdichte im Vergleich zum unbeeinflussten Wald im Schnitt um 17 %, im Extremfall bis zu 54 %. Einzeln betrachtet kann für die Bodenart ein starker Zusammenhang zwischen Feinboden, vor allem Schluff sowie Ton, und der Lagerungsdichte festgestellt werden. Ein Zusammenhang zwischen der Hangneigung und der Verdichtung des Bodens kann anhand der untersuchten Rückegasse nicht festgestellt werden. Die Anzahl der Befahrungen scheint im Untersuchungsgebiet mit dem Grad der Verdichtung einherzugehen.
This thesis is about the design and the implementation of a virtual reality experience. The goal is to answer two questions: Is it possible to create an immersive virtual reality experience which is mainly using impulses and triggers to scare and frighten users? Secondly, is this immersion strong enough to create an illusion in which the user can't separate the real world from the virtual world? To realise this project the design program Unity3D as well as Visual Studios 2017 were used. Furthermore, in order to verify that the experience is indeed immersive for the user, an experiment with a sample size of seven people was created. Afterwards the candidates were interviewed via a questionnaire how they felt during the virtual reality application. As a result the study showed that the application has tendencies to be immersive but the users were still aware of the situation. It can be concluded that the immersion was not strong enough to fool users regarding the separation of virtual and real world.
This bachelor thesis implements a system for camera tracking based on a particle filter. For this purpose, a marker tracking is realized and the camera position is calculated based on the marker position. The marker is to be found with a particle filter and in order to accomplish this possible marker positions are simulated, also called particles, and weighted with Likelyhood-Functions. The focus lies on the evaluation of different Likelihood-Functions of the particle filter. The Likelyhood functions were implemented in CUDA as part of the implementation.
This thesis deals with the conception and implementation of an action role-playing game using the game engine Unity. Within the context of an evaluation, the game was supposed to be evaluated with regard to the usability of the integrated control modes, the visual conviction of the animations and the user-friendliness of the tools and visualizations provided. In addition, weaknesses and problems in the game were to be identified through open feedback. The results of the evaluation showed that the game is still expandable in terms of usability and user-friendliness, but has left a good impression on the test persons.
The main goal of this paper is to ascertain, if neural networks (especially LSTM) are helpful in predicting processes by making predictions as accurately as possible.
TensorFlow is the used framework in Python to build recurrent neural networks. Two networks are built, whereby one is used for training and the other one for prediction.
Used datasets contain several processes with several events each. With those processes, the network ist trained and afterwards, the parameters are saved. The network for prediction uses these parameters to make predictions.
The neural network is able to make clear predictions about subsequent events. Even branches can be predicted.
When developed further, integration in other programs is possible. It is recommended to use unique names for the events or to rename them.

Die vorliegende Bachelorarbeit untersucht die Namens-, Besitz- und Nutzungsgeschichte des sogenannten Templerhauses, einem massiven Profanbau der Stauferzeit in Boppard (Rheinland-Pfalz). Nach einer Beschreibung des heutigen Erscheinungsbildes und der Erarbeitung früherer Zustände erfolgt ein stilkritischer Vergleich mit ausgewählten Beispielen der Umgebung, der Rekonstruktionsversuch früherer Bauphasen und eine Einordnung in den städtischen Kontext.
Simulation von Schnee
(2019)
Using physics simulations natural phenomena can be replicated
with the computer. The aim is to calculate a physical feature as correclty as
possible in order to draw conclusions for the real world. Fields of Application
are, for example, medicine, industry, but also games or films.
Snow is a very complex natural phenomenon due to its physical structure
and properties. To simulate snow, different material properties have to be
considered.
The most important method that deals with the simulation of snow and its
dynamics is the material point method. It combines the Lagrangian particles
based on continuum mechanics with a Cartesian grid. The grid enables
communication between the snow particles, which are not actually connected.
For calculation of particles data is transferred from these particles to
the grid nodes. There, calculations are carried out with information about
neighboring particles. The results are then transferred back to the original
particles. Using GPGPU techniques, physical simulations can be implemented
on the graphics card. Procedures like the material point method
can be parallelized well with these techniques.
This paper deals with the physical basics of the material point method and
implements them on the graphics card using compute shaders. Then performance
and quality are evaluated.
