Human civilisation has undergone a continuous trajectory of rising sociopolitical complexity since its inception; trend which dramatic recent acceleration. This phenomenon resulted in increasingly severe perturbation the Earth System, manifesting recently as global-scale effects such climate change. These create an increased risk global ‘de-complexification’ (collapse) event could undergo wides...

We study passive and nonlinear targeted energy transfers induced by resonant interactions between a singledegree-of-freedom nonlinear energy sink (NES) and a 2-DOF in-flow rigid wing model.We show that it is feasible to partially or even completely suppress aeroelastic instability by passively transferring vibration energy from thewing to the NES in a one-way irreversible fashion. Moreover, thi...

[1] When conducting model averaging for assessing groundwater conceptual model uncertainty, the averaging weights are often evaluated using model selection criteria such as AIC, AICc, BIC, and KIC (Akaike Information Criterion, Corrected Akaike Information Criterion, Bayesian Information Criterion, and Kashyap Information Criterion, respectively). However, this method often leads to an unrealis...

Interlacing causes complications in many image processing tasks. Theoretically, interlacing can be perfectly undone, but there remain a few difficulties in de-interlacing. Aliasing is an inherent artifact due to the interlaced sampling of video data. Interlacing also causes the loss of vertical resolution in the video. Motion in the video scenes need to be modelled accurately for the removal of...

In this paper, we suggest an empirical Bayes-type prior for the model space in Bayesian model averaging (BMA) in a method we call tuned Bayesian model averaging (tBMA). This method relies on leave-one-out cross validation to choose a hyper-parameter that will cause the averaging process to favor either smaller or richer models in the prior distribution over the models. We find that this method ...

Additive iterative method in combination with averaging of dithered samples is designed for self-correction of ADC linearity error in the paper. Iterative method is one of the automated error correction techniques. Dithering is a special tool for quantizer performance enhancement. Dither theory for Gaussian noise and averaging has been used for exhibition of method abilities in ADC characterist...

The orthogonal and unitary calculi give a method to study functors from the category of real or complex inner product spaces based topological spaces. We construct between complexification-realification adjunction These allow for movement versions calculi, comparisons Taylor towers produced by both calculi. show that when inputted functor is weakly polynomial, tower restricted through realifica...

In this paper the description of the simplest variant of conservative averaging method for partial differential (or integro-differential) equations in cylinder type domain is given. Different types of boundary conditions (both linear and non-linear) are considered. As application of the method the process of intensive steel quenching as the time inverse ill-posed problem for the hyperbolic heat...

Holographic speckle is a major impediment for the emerging applications of multiphoton holographic projection in biomedical imaging, photo-stimulation and micromachining. Time averaging of multiple shifted versions of a single hologram ("shift-averaging") is a computationally-efficient method that was recently shown to deterministically eliminate holographic speckle in single-photon application...
