Optimal Short-Circuit Resilient Formulas
We consider fault-tolerant boolean formulas in which the output of a faulty gate is short-circuited to one of the gate’s inputs. A recent result by Kalai et al. [FOCS 2012] converts any boolean formula into a resilient formula of polynomial size that works correctly if less than 1/6 of the gates (on every input-to-output path) are faulty.

Active Reduction of Short-Circuit Current in Power Distribution Systems
In this paper, a new concept of short-circuit current (SCC) reduction for power distribution systems is presented and analyzed. Conventional fault current limiters (FCLs) are connected in series with a circuit breaker (CB) that is required to limit the ...

Characteristics of Short-Circuit Current in Distribution Network with Doubly-Fed Wind Power System
The doubly-fed induction generator (DFIG) is connected to the distribution network as a distributed power source, which turns a radial single power supply system into a dual power supply system and changes the topology of the distribution network. When a

SHORT CIRCUIT OF THE VAS DEFERENS [PDF]
By short circuit of the vas I mean joining together the patent lumen of the vas with a section of the epididymis or testicle. Just a word regarding the anatomy of these parts in order to make the following clear. The testis is composed of an enormous number of much convoluted seminiferous tubules, which fill up the intervals between the septums. These
