ORI GIN AL PA PER Automated synthesis of resilient and tamperevident analog circuits without a single point of failure
"... Abstract This study focuses on the use of genetic programming to automate the design of robust analog circuits. We define two complementary types of failure modes: partial shortcircuit and partial disconnect, and demonstrated novel circuits that are resilient across a spectrum of fault levels. In p ..."

Initial TORPEX results of plasma production, connement and uctuation studies
"... TORPEX (TORoidal Plasma EXperiment) [1, 2] is a toroidal device for basic plasma physics research, with major radius R 1m; minor radius a 0 2m; toroidal and vertical magnetic eld, Btor 0 1T, Bv 5mT. Plasmas are generated by a microwave power source that can deliver up to 50kW at a frequency νR ..."

by superimposing a small vertical component over the dominant toroidal magnetic eld [3]. The spiralshaped eld lines allow particles to partially shortcircuit the vertical electric eld Ez driven by charge dependent ∇B and curvature drifts. Coulomb collisions limit this shortcircuiting effect, allowing
Analysis of High Power IGBT Short Circuit Failures
, 2005
"... proposal at SLAC requires a highly efficient and reliable, low cost, pulsedpower modulator to drive the klystrons. A solidstate induction modulator has been developed at SLAC to power the klystrons; this modulator uses commercial high voltage and high current Insulated Gate Bipolar Transistor (IGB ..."

(IGBT) modules. Testing of these IGBT modules under pulsed conditions was very successful; however, the IGBTs failed when tests were performed into a low inductance short circuit. The internal electrical connections of a commercial IGBT module have been analyzed to extract self and mutual partial
Research on PMSM Demagnetized by Three Phase Symmetrical Short Circuit
"... AbstractThe partial demagnetization of surfacemounted permanent magnets of PMSM in the three phase symmetrical short circuit of different temperature is analyzed by the finite element method. Then, rules of the back EMF and flux change in different extent of demagnetization are summarized. Finally ..."

On the Design of Reliable Boolean Circuits that Contain Partially Unreliable Gates
, 1994
"... We investigate a model of gate failure for Boolean circuits in which a faulty gate is restricted to output one of its input values. For some types of gates, the model (which we call the shortcircuit model of gate failure) is weaker than the traditional von Neumann model where faulty gates always ..."

DESIGN OF A GRID CONNECTED CONVERTER WITH HIGH SHORT CIRCUIT CURRENT CAPABILITIES
"... Due to the recent and future increase of the distributed generators there is a rising need to review the concept of the traditional electric distribution grid [1, 2]. This has led to the development of the "Microgrid " concept. A Microgrid is a small partial grid located on the secondary ..."

addressed to the utility grid. Short circuit currents that are needed to trigger the protection devices are delivered by the big rotating mass from the generators in the power stations. In the "Microgrid " concept there is a lack of rotating mass when it is in island mode [2, 3]. Distributed
ABSTRACT PARTIAL CAD I: THE LIFTING PHASE
, 2011
"... Though decidable, the theory of real closed fields (RCF) is fundamentally infeasible. This is unfortunate, as automatic proof methods for nonlinear real arithmetic are crucially needed in both formalised mathematics and the verification of realworld cyberphysical systems. Consequently, many resear ..."

In particular, we present an extension of the RCF quantifier elimination method Partial CAD (PCAD) which uses incomplete ∃ RCF proof procedures to “shortcircuit” expensive computations during the lifting phase of PCAD. We present the theoretical framework as well as preliminary experiments
Safety Analysis of Solar Module under Partial Shading
"... Hot spot often occurs in a module when the qualities of solar cells mismatch and bypass diodes are proved to be an efficient alternative to reduce the effect of hot spot. However, these principles choosing a diode are based on the parameters of bypass diodes and PV cells without consideration of th ..."
