A study on dynamic avalanche test of IGBT module

open access: yes机车电传动, 2023
During the turn-off of IGBT modules, dynamic avalanche will occur when a large electric field is generated inside the chip. In this paper, an experimental scheme was designed and verified to analyze the effect of different factors on dynamic avalanche ...

Constructions of pseudorandom binary lattices using cyclotomic classes in finite fields

open access: yesOpen Mathematics, 2020
In 2006, Hubert, Mauduit and Sárközy extended the notion of binary sequences to n-dimensional binary lattices and introduced the measures of pseudorandomness of binary lattices.

Improved SM3 Algorithm Based on Error-correcting Code

open access: yes工程科学与技术, 2023
Cryptanalysts now can effectively find the collisions of MD5, SHA1 and other international hash algorithms in a short time. Increasing entropy to enhance the randomness of hash value is an effective way to improve the anti-collision performance of hash ...

Non-equilibrium hysteresis and spin relaxation in the mixed-anisotropy dipolar coupled spin-glass LiHo$_{0.5}$Er$_{0.5}$F$_{4}$ [PDF]

open access: yes, 2014
We present a study of the model spin-glass LiHo$_{0.5}$Er$_{0.5}$F$_4$ using simultaneous AC susceptibility, magnetization and magnetocaloric effect measurements along with small angle neutron scattering (SANS) at sub-Kelvin temperatures.

Subsampling effects in neuronal avalanche distributions recorded in vivo [PDF]

open access: yesBMC Neuroscience, 2009
Many systems in nature are characterized by complex behaviour where large cascades of events, or avalanches, unpredictably alternate with periods of little activity. Snow avalanches are an example. Often the size distribution f(s) of a system's avalanches follows a power law, and the branching parameter sigma, the average number of events triggered by ...

Detrainment and braking of snow avalanches interacting with forests [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2022
Mountain forests provide natural protection against avalanches. They can both prevent avalanche formation in release zones and reduce avalanche mobility in runout areas.
