Simultaneous optimized orthogonal matching pursuit with application to ECG compression.
PLoS ONEA greedy pursuit strategy which finds a common basis for approximating a set of similar signals is proposed. The strategy extends the Optimized Orthogonal Matching Pursuit approach to selecting the subspace containing the approximation of all the signals

Interdependences between finger movement direction and haptic perception of oriented textures.
PLoS ONE, 2018 Although the natural haptic perception of textures includes active finger movements, it is unclear how closely perception and movements are linked. Here we investigated this question using oriented textures.

Detecting and tracking time-varying causality with applications to EEG data [PDF]
, 2011 This paper introduces a novel method called the ERR-Causality, or Error Reduction Ratio Causality test, that can be used to detect and track causal relationships between two signals using a new adaptive forward orthogonal least squares (Adaptive ...

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

NLOS Signal Detection Based on Single Orthogonal Dual-Polarized GNSS Antenna
International Journal of Antennas and Propagation, 2017 Nowadays users have a high demand for the accuracy of position and velocity, but errors caused by non-line-of-sight (NLOS) signals cannot be removed effectively. Since the GNSS signal is right-hand circular polarized (RHCP), the axial ratio of the strong

Orthogonal Transform Coding System for Television Signals
IEEE Transactions on Electromagnetic Compatibility, 1970 テレビ信号の帯域幅圧縮符号化の一方式として, 直交変換を利用するものについて論ずる.直交変換が有効に帯域圧縮方式に利用できるための条件について考察し, テレビ信号を対象とする場合は, アダマール行列を変形した傾斜直交変換が最も有利であることを示し, シミュレーションにより, 入物の顔写真について2.5ビット/サンプルで無評価で約32dBのSp-P/Nq rmsが得られた.また, この方式の実験結果についても述べた.
