Multiple frequencies constraints and analytical sensitivity methods were used in structural optimization design of the side plate of 4YK1860 vibrating screen to lower the damage of side plate caused by high dynamic stress. The mass of side plate of the vibrating screen was taken as object function, mode frequencies were regarded as state parameters, size of plate were used as constraint paramet...

We investigate data driven natural language generation under the constraints that all words must come from a fixed vocabulary and a specified word must appear in the generated sentence, motivated by the possibility for automatic generation of language education exercises. We present fast and accurate approximations to the ideal rejection samplers for these constraints and compare various senten...

We investigate natural inflation with non-minimal coupling to gravity, characterized either by a quadratic or periodic term, within the warm paradigm during slow-roll stage, in both strong and weak dissipation limits; show that, case of T-linearly dependent dissipative it can accommodate spectral index ns tensor-to-scalar ratio r observables given Planck 2018 constraints, albeit too-small value...

Nonnegativity constraints arise frequently in statistical learning and pattern recognition. Multiplicative updates provide natural solutions to optimizations involving these constraints. One well known set of multiplicative updates is given by the ExpectationMaximization algorithm for hidden Markov models, as used in automatic speech recognition. Recently, we have derived similar algorithms for...

We propose a position-based approach for largescale simulations of rigid bodies at interactive frame-rates. Our method solves positional constraints between rigid bodies and therefore integrates nicely with other position-based methods. Interaction of particles and rigid bodies through common constraints enables two-way coupling with deformables. The method exhibits exceptional performance and ...
