„SAFE On-Line“-On-Line Health Monitoring for Rolling Stock Wheelset Axle

Early detection of an incipient crack in a rolling stock wheelset axle (see Figure 1) can help to avoid fatal train accidents and the high cost for corrective maintenance activities. Usually, the wheelset axles are checked by

conventional Ultrasonic Testing (UT) at pre-defined mileages. During the conventional UT, the train needs to be taken out of service.

SIISpine: Development of a robotic assistance system to support minimal invasive spine interventions with reduced radiation

Dorsal pain is a major reason in Germany for absence from work due to illness. The reason in many cases depends on instabilities of the spine, which may result from intervertebral disk lesions, fracture of a vertebra, or arthrosis. A common option for treatment is stiffening of the respective segment of the spine (spondylodesis). This intervention is among the most frequent spine surgeries in Germany with more than 72.000 cases per year (DRG statistics 2012).

PIREF – Process diagnostics and integrated closed loop control for increasing the efficiency

of hot rolling lines for steel bars and wire

Despite the fact that the performance of the bar and wire manufacturing plants has increased over the decades, the manufacturers, engineers, and operators are still struggling through various challenges (e.g. productivity,

product quality, production tolerances, costs, etc.). This is due to the complexity of the forming process in profile rolling. In addition, alternating materials have different influences on the forming process

and accordingly lead to cross-sectional variations, which deteriorates end products tolerances.

Aerodynamic Optimization of Centrifugal Fans Using Active Learning

Due to their significant contribution to the total electricity consumption of the European Union (nearly 10%), future minimum efficiency requirements for fans are set by EU regulations. As a consequence,

many currently available fans on the EU market may no longer be sold and the need for efficient design and optimization methods arises. In the context of the current project we focus on centrifugal fans.

KungFu - Optimization of visual ante-mortem inspection using computer vision

In the beginning of the 20th century the ante-mortem inspection of meat was introduced by the German Professor Dr. Robert von Ostertag. The goal was to contain diseases that could be transferred to humans by infected meat. Nowadays this is a standard procedure done by veterinarians. Due to new European laws in 2014, the ante-mortem inspection has to be done mainly visually to prevent cross-infection which increases the workload of the veterinarians. Concerning pig meat for example, dependent on the size of a slaughterhouse, 200-900 pigs must be inspected per hour.

Reformed gas engine for biogas power generation or combined heat and power plant

The aim of this project is to enhance the market opportunities and to further improve the environmental impact of small and intermediate combined heat and power (CHP) plants. Combined heat and power (CHP) plants convert regenerative generated biogas into power and heat, which can be fed into power or district heating grids. Due to technical reasons the production of heat is higher than power.

Graphene-based THz antennas for ubiquitous
communication devices

Compact antennas are a key determinant for the performance of all future ubiquitous smart devices. Graphene plasmonic micro-antennas with lateral dimensions of just a few micrometers can theoretically have area requirements up to four orders of magnitude smaller than classical metallic counterparts, indicating a huge potential, enabling radically miniaturized wireless communications, providing better integration at much lower cost......

Aerodynamic Optimization of Centrifugal Fans Using CFD-Trained Meta-Models

Due to their significant contribution to the total electricity consumption of the European Union (nearly 10%), future minimum efficiency requirements for fans driven by motors with an electric input power between 125 W and 500 kW are set by EU regulations. As a consequence many currently available fans on the EU market may no longer be sold and the need for efficient design and optimization methods arises. In the context of the current project we focus on centrifugal fans.....

AVIRO - Modular Perception System for Space Robotics

The effective control of robots needs an exact environment model together with a current state description. The aim of AVIRO is the development of such a system. To generate a robust three dimensional model of the environment, the system can be mounted with modular sensor devices. A multi-sensorfusion combines the data of several connected units in real-time. Parallel to this, position, attitude and speed of the system are determined continuously....
