Embedded systems, which are safety critical, are frequently analyzed to find out whether they follow the safety standards and to improve their safety. Fault tree analyses enable the safety analysts to find possible causes of a system’s failure or unsafe behavior. From a fault tree, minimal cut sets are computed giving unique combinations of basic events that cause such a failure. Using minimal ...

We show that one-loop amplitudes in massless gauge theories can be determined from single cuts. By cutting a single propagator and putting it on-shell, the integrand of an n-point one-loop integral is transformed into an (n + 2)-particle tree level amplitude. The single-cut approach described here is complementary to the double or multiple unitarity cut approaches commonly used in the literatur...

Multitasking is an important part of today’s manufacturing plants. Multitask machine tools are capable of processing multiple operations at the same time by applying a different set of part and tool holding devices. Mill-turns are multitask machines with the ability to perform a variety of operations with considerable accuracy and agility. One critical factor in simultaneous machining is to cre...

BACKGROUND A fiberglass short arm cast can be used to treat a distal radial fracture, but posttraumatic edema may lead to excessive cast tightness and resultant soft-tissue injury. We sought to quantify a simulated edema-induced pressure within a fiberglass short arm cast and to determine the effectiveness of different cast-cutting methods for pressure reduction. We hypothesized that cast cutti...
