Research Projects


Modal analysis of buildings under varying conditions, e.g. temperature or humidity

With the current operational modal analysis, minor damage to structure is often not recognized at all or discovered too late to be treated properly. Therefore, the project focused on the detection of damages, e.g. caused by changes in temperature or humidity, and the improvement of the modal analysis by means of wavelet transformations.

Data and forecast based generation of model parameters for mechanical joints under crash loads

The aim of this research project is firstly to develop a forecasting capability for all mechanical joining technologies to determine joint properties of unknown joints. Experimental and predicted data serve as a base for a finite element model for the crash simulation of mechanical joints. Secondly, the extension of an existing finite element model for self-piercing rivets to other mechanical joining technologies is provided. Another point is the development of an approach for the automated calibration of a finite element model for crash simulation using experimental and prediction based data. The validation of the forecasts of joint properties and the finite element model for crash simulation are performed by using experiments and simulation of specimen and component tests.

Innovative 3D color barcode

A new color barcode that allows individual design in color and shape by integrating the code pattern directly into existing color images and graphics. The free choice of design, shape and colors allow a wide range of coding templates. The unique coding pattern can be recognized easily and distinguishes coded from uncoded images.

Detection of an increased risk of a complication during the use of an extracorporeal VAD

A monitoring system based on all types of sound data was developed. In cooperation with ourlong-term partner Berlin Heart GmbH, an autonomous condition monitoring system for the EXCOR® cardiac support system was developed . A special ultrasonic signal is used to record the diaphragm status of the heart pump. The evaluation and classification is carried out using AI.
