Industrial robots are used in many diferent felds of application: from huge welding production lines for automobiles to assembly tasks in Small and Medium-sized Enterprises (SMEs). Such robot systems require specially trained employees, who know how to program these robots and how to teach them new tasks using TeachPads and specifc programming languages like KRL (Kuka) or RAPID (ABB). Programmi...

I Circa 1.1 Ga granitic magmatism in Texas was manifested as two compositional groups: (1) the 1.12 Ga Red Bluff granitic suite in west Texas; and (2) 1.12-1.07 Ga granites of the Llano uplift of central Texas. Both suites share some characteristics typical of 'anorogenic' granites (e.g. potassiumand iron-rich bulk compositions, Fe-rich hydrous silicates, emplacement conditions involving low ox...

Komplexe Punktionseingriffe in der Leber werden heutzutage CT-gesteuert durchgeführt. Vorangegangene Forschungsarbeiten zeigten einen hohen Nutzen computer-assistierter Systeme, die mit optischem Tracking arbeiten. Derartige Systeme konnten sich nicht im klinischen Alltag durchsetzten, unter anderem wegen der benötigten direkten Sichtlinie. Um zu untersuchen, ob EM Tracking für präzise Leberpun...

The deformational properties of gas shale reservoir rocks from the Barnett and Haynesville shale formations were investigated using a triaxial apparatus. The samples tested varied in their mineralogical composition, the degree of diagenesis, the total organic content and the degree of maturity of the organic material. In general, rocks with more cement and less clay show higher elastic moduli, ...

Nachdem erstmals ein Einzelelektronen-Quantenpunkt in zweilagigem Graphen gezeigt wurde, folgten kurzer Zeit wegweisende Experimente. Dazu zählen die Untersuchung des Ein- und Zweiteilchenspektrums, der Elektronen-Loch-Übergang, kontrollierbare Kopplung von Quantenpunkten, Ladungsdetektion, Pauli-Blockade hier gezeigten Messungen Spin-Relaxationszeit. Diese Experimente tragen wesentlich zum Ver...

In recent months, attacks on servers of payment processors have led to the disclosure of tens of millions of credit card numbers (also known as Personal Account Numbers, PANs). As an answer, end-to-end encryption has been advocated and an encryption standard that preserves the format of the data would be welcome. More generally, a format-preserving encryption scheme would be welcomed for many r...
