Study of Channel Characteristics for Galvanic-Type Intra-Body Communication Based on a Transfer Function from a Quasi-Static Field Model

open access: yesSensors, 2012
Intra-Body Communication (IBC), which modulates ionic currents over the human body as the communication medium, offers a low power and reliable signal transmission method for information exchange across the body.

The use of the chatter mode in self-adaptive systems [PDF]

open access: yes, 1970
Chatter mode is used advantageously if the ideal model dynamics is described by a switching function, the chatter mode is reached quickly and then sustained, the chatter frequency is reduced, and any zero in the plant transfer function is ...

Dual Resonance Model Solves the Yang-Baxter Equation

open access: yes, 1997
The duality of dual resonance models is shown to imply that the four point string correlation function solves the Yang-Baxter equation. A reduction of transfer matrices to $A_l$ symmetry is described by a restriction of the KP $\tau$ function to Toda ...

Statistical Time Series Models of Pilot Control with Applications to Instrument Discrimination [PDF]

open access: yes, 1984
A general description of the methodology used in obtaining the transfer function models and verification of model fidelity, frequency domain plots of the modeled transfer functions, numerical results obtained from an analysis of poles and zeroes obtained

Transfer functions

open access: yesIOP Conference Series: Earth and Environmental Science, 2011
This chapter summarizes the different approaches used to reconstruct past environmental conditions from micropaleontological proxy data. The first group of methods involves calibration, i.e. a relationship is calculated between a given environmental variable and the abundances of the various species (e. g. regression, partial least squares). The second

Transfer function characteristics of super resolving systems [PDF]

open access: yes
Signal quality in an optical storage device greatly depends on the optical system transfer function used to write and read data patterns. The problem is similar to analysis of scanning optical microscopes.

New tools for determining the light travel time in static, spherically symmetric spacetimes beyond the order $G^2$

open access: yes, 2014
This paper is mainly devoted to the determination of the travel time of a photon as a function of the positions of the emitter and the receiver in a large class of static, spherically symmetric spacetimes.

Dispersion of the dielectric function of a charge-transfer insulator

open access: yes, 2003
We study the problem of dielectric response in the strong coupling regime of a charge transfer insulator. The frequency and wave number dependence of the dielectric function $\epsilon ({\bf q},\omega)$ and its inverse $\epsilon ^{-1}({\bf q},\omega)$ is ...

Synthesis of arbitrary current mode filter

open access: yesTongxin xuebao, 2010
A new general analytical synthesis method for arbitrary current mode filter was presented.The method was based on the analytical decomposition of a complicated high-order transfer function into n lossless integrators and n cur-rent proportional blocks by

Multivariable Control of Solar Battery Power by Extremum Seeking: Starting from Linear Analysis

open access: yesMachines, 2019
In this study, we tried to combine maximum power point trackers (MPPT) and «Extremum Seeking» in a single multi-parameter extremum seekeng system for orienting solar panels and draw attention to the problem of a deeper study of nonlinear ...
