Atomic-cascade experiment with detection of the recoil atom
(1994)
Bell's inequalities cannot be violated in atomic-cascade experiments, even with ideal apparatus, due to the three-body character of the atomic decay. Here we propose a new experiment that would block this loophole by means ...
Technique for authentication, access control and resource management in open distributed systems
(1994)
A consistent approach to authentication and access control is proposed. In this new approach, resource management is included. By combining the properties of public key encryption with cascading proxies a single mechanism ...
The variability in the UV resonance lines of the cataclysmic variables MU Cen, AH Her and QU Car
(1994)
We present a time-variability study of the uV resonance lines Nv 1240, Si iv 1397 and C iv 1549 in the dwarf novae AH Her and MU Cen and the nova-like variable QU Car. The main findings are as follows. (i)Virtually no ...
Soft x-ray observations of the early b-giants beta and epsilon CMA
(1994)
The study reports observations performed with the PSPC on board the Roentgensatellit (ROSAT) of the two nearby giant stars Beta CMa (B1 II-III) and Epsilon CMa (B2 II). Upper limits in the region of +/- 10 percent can be ...
