Visualization of WiFi Signals Using Programmable Transfer Functions [PDF]
Information, 2022 In this paper, we show how volume rendering with a Programmable Transfer Function can be used for the effective and comprehensible visualization of WiFi signals. A traditional transfer function uses a low-dimensional lookup table to map the volumetric scalar field to color and opacity.

Transfer functions linking neural calcium to single voxel functional ultrasound signal [PDF]
Nature Communications, 2020 AbstractFunctional ultrasound imaging (fUS) is an emerging technique that detects changes of cerebral blood volume triggered by brain activation. Here, we investigate the extent to which fUS faithfully reports local neuronal activation by combining fUS and two-photon microscopy (2PM) in a co-registered single voxel brain volume.

Transfer Function between EEG and BOLD Signals of Epileptic Activity [PDF]
Frontiers in Neurology, 2013 Simultaneous electroencephalogram (EEG)-functional Magnetic Resonance Imaging (fMRI) recordings have seen growing application in the evaluation of epilepsy, namely in the characterization of brain networks related to epileptic activity. In EEG-correlated fMRI studies, epileptic events are usually described as boxcar signals based on the timing ...

Objective and efficient terahertz signal denoising by transfer function reconstruction [PDF]
APL Photonics, 2020 As an essential processing step in many disciplines, signal denoising efficiently improves data quality without extra cost. However, it is relatively under-utilized for terahertz spectroscopy.

Metasurfaces with Asymmetric Optical Transfer Functions for Optical Signal Processing [PDF]
Physical Review Letters, 2019 Metasurface thin films created from arrays of structured optical elements have been shown to perform spatial filtering of optical signals. To extend their usefulness it is important that the symmetry of their response with changes to the in-plane wave vector k_{p}→-k_{p} can be tailored or even dynamically tuned.

Analysis of room transfer function and reverberant signal statistics [PDF]
The Journal of the Acoustical Society of America, 2008 For some time now, statistical analysis has been a valuable tool in analyzing room transfer functions (RTFs). This work examines existing statistical time-frequency models and techniques for RTF analysis (e.g., Schroeder's stochastic model and the standard deviation over frequency bands for the RTF magnitude and phase). RTF fractional octave smoothing,

Transfer function approach to understanding periodic forcing of signal transduction networks [PDF]
Physical Biology, 2023 Abstract Signal transduction networks are responsible for transferring biochemical signals from the extracellular to the intracellular environment. Understanding the dynamics of these networks helps understand their biological processes. Signals are often delivered in pulses and oscillations.

Transfer Across Different Machines by Transfer Function Estimation
Frontiers in Artificial Intelligence, 2022 A digital twin is a promising evolving tool for prognostic health monitoring. However, in rotating machinery, the transfer function between the rotating components and the sensor distorts the vibration signal, hence, complicating the ability to apply a ...

A Comparison of PCA and LBF Based Multireceiver SAS Imaging Algorithms
IEEE Access, 2023 Multireceiver synthetic aperture sonar (SAS) is a useful tool to provide high-resolution images. The most important step lies in developments of multireceiver synthetic aperture image formation processors, which uses the sonar echoed signal as the input.
