Für den Ersatz des bestehenden Relais-Stellwerk der Bahn muss ein Interface für den bestehenden Stellwerkstisch bereitgestellt werden. Der Stellwerkstisch ist mit einer computergesteuerten SPS-Ansteuerung implementiert.

Die SPS Kommandos sollen in einer dezidierten Interface-Karte in Ethernetpakete abgepackt und an die Steuerung des Stellwerkes versandt werden.

Currently, especially athletes and tech geeks are using tools that allow to measure and track body functions like pulse, blood pressure, or respiration. However, the trend towards measurement of bodily functions is increasing steadily, while the possibilities of data acquisition are constantly being extended.

The goal of this work is to develop a new tool that allows a human to learn to control non-visible body functions through visual feedback provided by the tool. This involves selecting a number of matching measuring devices, finding and creating suitable visualizations for the generated data in real-time, and exploring the potential of this newly created tool.

Tilting trains can travel at higher speeds without degrading the passenger comfort. However, these higher speeds lead to larger rail-wheel interaction forces. This larger forces have to be monitored in order to maintain general safety (e.g. to prevent derailment). The monitoring can be done with specially equipped passenger trains (On Board Monitoring “OBM”, as it is the case with the ICN types of trains), or with measurement trains like the VT612. These procedures are very cost-intense. Additionally, if limit violations are observed, it is often difficult to figure out what caused this effect.

The field of ML is growing up. In the past, questions like “which AI algorithm should I choose” and “what is the best way to train it” were the main focus of AI projects. Today, these topics are well explored. Startups and big cloud providers offer services to ease the first steps and usage of AI. In addition, we can use publicly available, pre-trained models and use transfer learning to get a sound predictive performance with less effort than building our own model from scratch.

Now, new questions get into focus: how can we bring our model actually to production in a reliable and reproducible way? How can we integrate data acquisition, training, and monitoring of our model into an automated system?

Quantum computers might revolutionize the world of technology. Classical computers use bits to store information in binary states. Quantum computers use qubits that can exist in entangled multiple states at once. This feature allows quantum computers to be exceedingly more efficient than current computers. With today’s computers, all encryption schemes – incl. cryptocurrencies like Bitcoin – are impossible to break in reasonable time. However, quantum computers may be able to quickly break current encryption schemes in the upcoming future.

Eine Herausforderung beim Betrieb von elektrifizierten Bahnstrecken ist die Überwachung von Elementen (z.B. Weichen) und deren Verkabelung in der Aussenanlage. Ein weit verbreitetes Verfahren ist die Überwachung der Adern durch einen Ruhestrom. Speziell bei den heute immer noch weit verbreiteten Lösungen auf Relaisbasis ist die Überwachung des Stromes sehr eingeschränkt. Kurzschlüsse und der Einfluss von Fremdspannungen bleiben daher oft unerkannt. weiterlesen

OverviewTechnical maintenance on ticket vending machines requires a high level of expertise. Technicians usually need many weeks to get a good understanding of the vending machines, under the tight supervision of their mentor. The goal of the present study is to design and implement an AR (Augmented Reality) system that will facilitate the work of the technicians and reduce their apprenticeship time. In fact, this AR solution will provide in real-time the necessary information with the corresponding documentation of the component that needs maintenance. For instance, a technician will be able to immediately scan the different components in the TVM and determine which are the cables that must be connected between them. weiterlesen

Stereo Vision allows accurately measuring scenes in 3D – provided that the cameras are well calibrated (camera pose, intrinsic parameters). Especially in harsh industrial or automotive contexts, the mechanical vibrations, temperature variations, and material fatigue affect opto-mechanical properties of the stereo-rig and its measurement accuracy.A jointly developed intelligent door opener (embedded stereo-system: reglomat.bircher.com) can detect, discriminate (humans, vehicles), and track 3D objects in real-time. This enables adequate door openings, e.g. suppressing cross-traffic and accounting for the object’s height to minimize energy loss in cooling storage applications. Because calibration drifts can cause e.g. inappropriate openings/closing, periodic or continuous recalibration of the stereo-rig is advantageous.The goal of this thesis is to explore, test and analyze different methods and algorithms for continuous stereo-vision calibration. The solution has to determine the extrinsic and intrinsic camera parameters without any markers or reference objects. Its performance will be measured mainly in overall accuracy, but also calculation time and memory consumption.
