BaBeDa is a passive energy self-sufficient data logger for detection and documentation of shock events. A piezoelectric element is used as an acceleration sensor, since it – depending on the magnitude of the acceleration – produces electrical signals during a shock. These electrical signals are used both as a measurement signal and as power source for the circuit, which stores the data concerning the shock event. BaBeDa can be used in particular for shock detection in shipping. In the packing stations and logistics centers each BaBeDa chip can be read out to determine whether a packet was transported properly or not.
For this purpose BaBeDa can already be integrated into a packing during its production. Multiple usage is possible. Since BaBeDa is energy self-sufficient, there are no restrictions on the use of time. Because of the simple technique BaBeDa is compact, suitable for mass production and therefore also very cost effective.

New research has identified clear signs that the hole in the Antarctic ozone layer is beginning to close.

Congestion occurs in packet-based communication networks when more traffic temporarily enters a network than can be forwarded. Congestion management detects congestion in a communication network and drops or marks packets to mitigate congestion. Still, a few heavy users can monopolize the bandwidth of a bottleneck link, e.g., by opening many flows or using non-responsive transport protocols to send at large data rate. A challenge is to drop or mark the right packets if fair capacity sharing and low delay are desired in a network.
We propose activity-based congestion management (ABC), with which users can share a network’s capacity fairly within an ABC domain while keeping packet delays low. To that end, activity meters and markers equip user traffic with activity information that reflects a user’s traffic rate. In case of congestion, traffic with high activity is preferentially dropped on bottleneck links. Thereby, users can achieve a fair share of the network’s transmission capacity.
Low delay is achieved by leveraging active queue management (AQM) in routers or switches that start dropping traffic in case of congestion to avoid extensive, permanent packet queueing. ABC-AQM is a modification of a normal AQM that increases drop probabilities for high-activity traffic and decreases them for low-activity traffic. The mechanism is easily adaptable to various AQMs.

The novel mathematical concept of tangles is for the first time applied to identify highly connected regions in a graph. The applications of this analysis technique include image recognition & compression, cluster analysis & data mining and data quality assessment.

Monitoring of fish swarms in muddy waters or during the night with new procedure for operating and reading out of multi static sonars.

The invention offers an autoantibody set that can be used as a diagnostic tool for diagnosis and stratification of colorectal cancer patients.

The assay detects lgM antibodies with high sensitivity and specificity and thus provides a means for the early serological diagnosis of flavivirus infections. lt is based on an lgM-capture format and highly purified recombinant viral antigens, allowing the differentiation between infections with antigenically closely related flaviviruses like dengue and Zika viruses. The lgM-capture format is robust, can be easily standardized and readily adapted to existing diagnostic systems for antibody detection.

Lasers have become indispensable to modern life since they were invented more than fifty years ago. The ability to generate and amplify light waves into a…

During laser beam welding the focus position of the laser beam should be on the workpiece surface. With the present invention, this focus position can be detected in relation to the workpiece. Thus, the process can be set up quickly, but also the focus shift could be compensated. Also, this method can prepare the basis for calibrating scanner optics.

The study of biological samples often relies on fluorescence microscopy. Image processing is often difficulted by inefficient methodologies, dependent on the operator. We offer a new platform for automated image analysis which can, in turn, automatically optimize image acquisition parameters on the microscope and can be adapted to any microscope control operative software.
