Collecting Cookie Data And Still Protecting Privacy
2014-03-07 14:38:14

Enid Burns for redOrbit.com - Your Universe Online The browser cookie has long been debated as a troubling side effect of the Internet. Privacy advocates and consumers fear that data collected from cookies are used in nefarious ways. However, publishers typically use the data to understand a site's visitors and target advertising. A group of cryptology engineers at the Saarland University in Germany is the most recent group to tackle the cookie issue, this time by using a cryptographic...

repair at a distance
2014-02-20 13:00:36

Saarland University This news release is available in German. Numerous German companies are operating globally these days: They develop products domestically, but production is done in other countries like China, Brazil or the Czech Republic. If maintenance or repair work is needed, the engineers who had designed the complex production plants frequently have to travel from Germany. A novel approach by computer scientists in the research group of professor Thorsten Herfet from the...

Computer Algorithm Developed That Arranges Pictures Based On Their Artistic Aspects
2014-02-18 15:54:51

Saarland University This news release is available in German. Until now, it has been a time-consuming process for a program to arrange pictures in a consistent order. It is even more complex to order them on the basis of visual characteristics. Computer scientists from Saarbrücken have developed a system to arrange pictures into a consistent order. It requires no more than a small number of pre-sorted example pictures. Operators of online portals or museums could use this technique,...

For a car to accelerate there has to be friction between the tire and the surface of the road. The amount of friction generated depends on numerous factors, including the minute intermolecular forces acting between the two surfaces in contact – so-called van der Waals forces. The importance of these intermolecular interactions in generating friction has long been known, but has now been demonstrated experimentally for the first time by a research team led by Physics...

Saarland University It could be a grotto. Light is glowing up from below and gives the moving waves a glance of an opal under the sunlight. "This computer graphic was written with our new description language by a schoolboy in not more than two hours after a briefly reading of the instructions", explains Felix Klein, doctoral candidate at the chair of Computer Graphics at Saarland University. As Klein is moving three slide switches with the mouse which are placed under the wave graphic on...

Lung Mucus Gel Prevents Nanoparticles From Getting Through
2012-10-23 10:54:10

Joint press release by the Saarland University and the Helmholtz Centre for Infection Research Mucus coats our airways' internal surfaces. The viscous gel humidifies the lungs and prevents viruses and other small particles like diesel soot from entering the body unchecked. Previously unclear was the extent to which such nanoparticles are able to move through the lungs' mucus. Here, the research evidence was contradictory. Scientists could not explain why, in inhaled medication development,...

The Center for IT Security, Privacy and Accountability (CISPA) of Saarland University, Germany, and the University of Luxembourg's Interdisciplinary Centre for Security, Reliability and Trust (SnT) have recently agreed upon a mutual course for the strategic development of new and integrative approaches to addressing key IT security concerns. "Every area of our daily lives is becoming increasingly more digitalized and interlinked. This trend is creates a number of novel security issues,...

It may be difficult to imagine, but pouring juice into a plastic cup can be a great challenge to a robot. While one hand holds the glass bottle firmly, the other one must gently grasp the cup. Researchers at Saarland University together with associates in Bologna and Naples have developed a robotic hand that can accomplish both tasks with ease and yet including the actuators is scarcely larger than a human arm. This was made possible by a novel string actuator, making use of small electric...

Automated Stress Testing For Web 2.0 Applications Helps Developers Find Programming Errors
2012-02-28 04:17:22

Web applications such as Google Mail, Facebook and Amazon are used every day. However, so far there are no methods to test them systematically and at low cost for malfunctions and security vulnerabilities. Therefore, computer scientists from Saarland University are working on automatic methods of testing, which check complex web applications autonomously. For the first time, they will present this work at exhibition booth F34 in hall 26 at the computer fair Cebit. The trade show will take...

Scientists in Saarbruecken provide free access to the enteric pathogen's genetic regulation data Just a few genes make enterohaemorrhagic E. coli (EHEC) extremely dangerous to humans. If it were not for these genes, EHEC would hardly differ from harmless enteric bacteria. Bioinformatics scientists from the Saarbrcken Cluster of Excellence want to exploit this similarity to find starting points for effective drugs against the EHEC pathogen. In a very short time, the scientists have constructed...
