A Fast Classification Method for Single-Particle Projections with a Translation and Rotation Invariant
Classification Fourier transform Translationand rotation invariant Secondary-class.
2012/8/7
The aim of the electron microscopy image classification is to categorize the projection
images into different classes according to their similarities. Distinguishing images
usually requires that the...
Bounds on the volume fractions of two materials in a three dimensional body from boundary measurements by the translation method
inverse problems size estimation electrical impedance tomography
2012/6/19
Using the translation method of Tartar, Murat, Lurie, and Cherkaev bounds are derived on the volume occupied by an inclusion in a three-dimensional conducting body. They assume electrical impedance to...
Translation invariant equations and the method of Sanders
Translation invariant equations the method of Sanders Number Theory Combinatorics
2011/8/26
Abstract: We extend the recent improvement of Roth's theorem on three term arithmetic progressions by Sanders to obtain similar results for the problem of locating non-trivial solutions to translation...
On the speed of biased random walk in translation invariant percolation
speed of biased random translation invariant percolation
2011/2/21
For biased random walk on the infinite cluster in supercritical i.i.d.percolation on Z2, where the bias of the walk is quantified by a parameter > 1,it has been conjectured (and partly proved) that ...
The translation operator for self-projective coalgebras
translation operator self-projective coalgebras
2011/1/17
We describe the transpose operator for self-projective and symmetric coalgebras in terms of the syzygy and Nakayama functors.
For a Radon measure $\mu$ on $\bbR,$ we show that $L^{\infty}(\mu)$ is invariant under the group of translation operators $T_t(f)(x) = {$f(x-t)$}\ (t \in \bbR)$ if and only if $\mu$ is equivalent to ...
Continuity of Pseudo-Differential Operator $h_{\mu,a}$ Involving Hankel Translation and Hankel Convolution on Some Gevrey Spaces
Hankel transformation Hankel translation Hankel convolu-tion Pseudo-differential operator
2010/12/9
The Pseudo-Differential Operator (p.d.o.) hμ,a associated with the Bessel Operator involving the symbol a(x, y) whose derivatives satisfy certain growth conditions depending on some increasing sequenc...
Examples of Minimal Diffeomorphisms on $t^{2}$ Semiconjugated to an Ergodic Translation
Examples of Minimal Diffeomorphisms Ergodic Translation
2010/11/29
We prove that for every ǫ > 0 there exists a minimal diffeomorphism f : T2 ! T2 of class C3−ǫ and semiconjugate to an ergodic traslation, and have the following properties: zero entrop...
Tilings by translation
Tilings translation
2010/12/9
To tile means to cover a given part of space, without overlaps, using a small number,often just one, of different types of objects. When we are covering the floor of a room using identical rectangular...
A translation: "Every" finite free resolution is a free resolution of an ideal generated by three elements
"Every" finite free free resolution ideal three elements
2011/2/28
In [4] and [7], Burch and Kohn proved that when R is a commutative Noetherian ring, and n a natural number that is the homological dimension 3 of a torsionless R-module, then there exists an ideal in ...
