Information overload? It is becoming increasingly important for companies and developers to present complex coherences clearly and concisely. In order to structure the growing amount of information, new methods are being conceived at the man/machine interface. This is where GoVisual software, developed at the international caesar research center, comes into play. It automatically generates a clear layout for a number of different diagrams in a second; particularly for UML (Unified Modeling Language) and cluster diagrams.
caesar (center of advanced european studies and research) will present the software from March 12-19 at the CeBIT in Hanover in Hall 3, Booth E50. The range of applications includes: business process modeling (organizational charts, workflow diagrams), databases (entity-relationship diagrams) as well as representations of technical and biological processes (phase diagrams, metabolic processes). GoVisual is available as a C++ program library with a Java or .NET interface for integrating with existing software or as a plug-in for Microsoft Visio 2000/2002. At CeBIT, new GoVisual Software products will be presented, which can be integrated as a plug-in into Poseidon Software (from Gentleware) as well as ControlCenter (previously from TogetherSoft, now Borland).
In the field of software engineering and re-engineering, UML diagrams are the new standard for displaying model information. UML class diagrams, which represent hierarchical and non-hierarchical relationships in a graphic, present a particular challenge for layout software. For the visualization of these multi-hierarchical diagrams GoVisual offers a unique technique which is based on powerful algorithms and modern methods of combinatorial optimization.

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
Graphene is up to the job
At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
