Algorithms and algebraic solutions of decay chain differential equations for stable and unstable nuclide fractionationRadioactive decay processes, such as alpha decay, produce decay chains where the mass numbers of nuclides decrease as larger nuclides expel energetic particles to form smaller nuclides. ...
Genetic AlgorithmsZiegler-Nichols methodVisioli methodDuring the last years the use of intelligent strategies for tuning Proportional-Integral-Derivative (PID) controllers has been growing. The evolutionary strategies have won an important place thanks to their flexibility. In this paper, the automatic ...
Stable memory with unstable synapses. a Left: Learning phase. Two distinct stimuli are sequentially presented to the network (green and blue shaded areas). Right: Retrieval phase. The embedded memories are read out of the network dynamics via a brief stimulation bearing partial information of the...
These real radix-2 stable algorithms are completely recursive, fast, and based on the simple orthogonal factors. Comparing to the known bulky and mostly unstable DST algorithms, our algorithms are easy to implement and use only permutations, scaling by constants, butterfly operations, and plane ...
The use of various models is studied to represent an I-beam for its elastic-plastic bending and torsional response including warping. The rectangular cross... KJ Bathe,PM Wiener - 《Computers & Structures》 被引量: 115发表: 1983年 Self-adaptive predictor-corrector algorithms for static nonlinear...
1c, owing to selection bias, there may exist spurious correlations between stable covariates S and unstable covariates V, resulting in changes in P(X). Thus unexpected correlation would mislead the model to learn the spurious correlation between V and T. This correlation P(T|V) is unstable ...
Learning Stable Classifiers by Transferring Unstable Featuresarxiv.org/abs/2106.07847 Motivation 如果只提供(input-label)对,算法可能没有足够的信息来区分稳定(causal)特征和不稳定(spurious)特征。 虽然源分类器在做出最终预测时没有偏见,但其内部的连续 representation 仍然可以编码关于不稳定特征的信息。 通过re...

We develop a multiple shooting parameterization method for studying stable/unstable manifolds attached to periodic orbits of systems whose dynamics is determined by an implicit rule. We represent the local invariant manifold using high order polynomials and show that the method leads to efficient numerica...
stable and unstable. The microscale investigations are then compared with constriction and particle size-based criteria. The findings reveal that the constriction-based criterion predicts internal instability with significantly better accuracy. The relationship between microscale parameters and the constriction-...
