Closed-loop separation control over a sharp edge ramp using Genetic Programming [PDF]
, 2015 We experimentally perform open and closed-loop control of a separating turbulent boundary layer downstream from a sharp edge ramp. The turbulent boundary layer just above the separation point has a Reynolds number $Re_{\theta}\approx 3\,500$ based on ...

Power Systems Topology and State Estimation by Graph Blind Source Separation [PDF]
IEEE Transactions on Signal Processing, 2018 In this paper, we consider the problem of blind estimation of states and topology (BEST) in power systems. We use the linearized dc model of real power measurements with unknown voltage phases (i.e., states) and an unknown admittance matrix (i.e ...

Single-Channel Blind Image Separation Based on Transformer-Guided GAN
Sensors, 2023 Blind source separation (BSS) has been a great challenge in the field of signal processing due to the unknown distribution of the source signal and the mixing matrix.

Separators - a new statistic for permutations
, 2019 A digit $ _j$ in a permutation $ =[ _1,\ldots, _n]\in S_n$ is defined to be a separator of $ $ if by omitting it from $ $ we get a new $2-$block. In this work we introduce a new statistic, the number of separators, on the symmetric group $S_n$ and calculate its distribution over $S_n$.

Geographic variation in walking activity in the red flour beetle Tribolium castaneum
Population Ecology, EarlyView.This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Current Sheet Statistics in the Magnetosheath
Frontiers in Astronomy and Space Sciences, 2020 The magnetosheath (MSH) plasma turbulence depends on the structure and properties of the bow shock (BS). Under quasi-parallel (Q||) and quasi-perpendicular (Q⊥) BS configurations the electromagnetic field and plasma quantities possess quite distinct ...

occumb: An R package for site occupancy modeling of eDNA metabarcoding data
Population Ecology, EarlyView.This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using
