Random number generators are used in many applications, from slot machines to simulations of nuclear reactors. For many computational science applications, such as Monte Carlo simulation, it is crucial that the generators have good randomness properties. This is particularly true for large-scale simulations done on high-performance parallel computers. Good random number generators are hard to f...

We consider the vulnerability of nuclear power plants to a disaster like the one that occurred at Fukushima Daiichi. Examination of Japanese nuclear plants affected by the earthquake and tsunami on March 11, 2011 shows that three variables were crucial at the early stages of the crisis: plant elevation, sea wall elevation, and location and status of backup generators. Higher elevations for thes...

Fax: +98 511 8419521 E-mail: [email protected] Background: 99mTc is a widely used radioisotope in nuclear medicine centers which is obtained by elution from Mo-99/Tc-99m generators. Usually the generators are either suppli...

We derive expressions for Poincaré group generators using preturbative similarity renormalization group procedure for Hamiltonians. We show that generators obtained in second-order perturbation theory satisfy required commutation relations in weak sense, i.e. in matrix elements between states of finite invariant masses. ∗Talk to be delivered at 12th Nuclear Physics Summer School and Symposium “...

We show that every separable $C^$-algebra of real rank zero tensorially absorbs the Jiang–Su algebra contains a dense set generators. It follows that, in classifiable, simple, nuclear $C^$-algebra, generic element is generator.

Nuclear power plant safety performance indicators are developed "by nuclear operating organisations to monitor their own performance and progress, to set their own challenging goals for improvement, and to gain additional perspective on performance relative to that of other plants". In addition, performance indicators are widely used by regulatory authorities although the use is not harmonised....

this paper proposes a novel approach for coherent generators online clustering in a large power system following a wide area disturbance. an interconnected power system may become unstable due to severe contingency when it is operated close to the stability boundaries. hence, the bulk power system controlled islanding is the last resort to prevent catastrophic cascading outages and wide area bl...
