Linearity and non-linearity in cerebral hemodynamics

Medical Engineering & Physics, 2003
Transcranial Doppler ultrasound has been extensively used to study cerebral hemodynamics, and yet the basic characteristics of the input/output system of blood pressure/velocity are little known. We examine whether this system can best be considered linear or non-linear.We assessed the adequacy of linear modeling in four ways: (1) Known properties of ...

Linear and non-linear filtering in stereopsis

Vision Research, 1994
To better understand the spatial filtering operations underlying stereopsis, and their relationship to those underlying monocular localization of the same stimuli, we examined the dependence of stereoacuity on carrier and envelope size of Gabor patches.

Linear Systems and Linearization

2010
Key to the analysis of nonlinear systems is determining the stability of the equilibria. The classical method of determining stability is to linearize the system about the equilibrium and to determine exponential rates of growth and decay for the associated linear system. The framework for carrying this out is taken up in this chapter.

On Linear Cryptanalysis with Many Linear Approximations

2009
In this paper we present a theoretical framework to quantify the information brought by several linear approximations of a block-cipher without putting any restriction on these approximations. We quantify here the entropy of the key given the plaintext-ciphertext pairs statistics which is a much more accurate measure than the ones studied earlier.

On the Independence of Linear Functionals of Linear Processes

SIAM Journal on Applied Mathematics, 1969
A class of continuous parameter random processes is defined whose members, $x(t)$, are integrals of a nonstationary random “filter” function, $h(t,\lambda )$, with respect to an independent increments process $Z(\lambda )$. Linear functionals l of $x(t)$ expressible as integrals of a random function $\phi (\lambda )$ with respect to $Z(\lambda )$ are ...

Non-linearity as the Metric Completion of Linearity

2013
We summarize some recent results showing how the lambda-calculus may be obtained by considering the metric completion (with respect to a suitable notion of distance) of a space of affine lambda-terms, i.e., lambda-terms in which abstractions bind variables appearing at most once.
