Joan Feigenbaum Technical Report YALEU/DCS/TR-­‐1448 December 2011 Support for anonymous communication in hostile environments is the main goal of DARPA’s “Safer Warfighter Communications” program (DARPA-­‐BAA-­‐10-­‐69: SAFER). Despite the fact that the word is regularly encountered in common parlance, “anonymity” is actually a subtle concept – one that the computer-­‐science community has ...

We report on numerical results for certain families of S-unimodal maps with flat critical point. For four one-parameter families, differing in their amount of flatness, we study the Feigenbaum-limits α and δ. There seems to be a finite δ and a finite α associated with each period doubling cascade in each family. Some rough numerical estimates are obtained. One would expect that these numbers sh...

Introduction Statistical process control (SPC) has been widely used as an aid for managing manufacturing processes. Many books have been published which outline the basics of SPC (e.g. Feigenbaum, 1983; Juran, 1975; Oakland and Followell, 1990), and organizations such as the Ford Motor Company (1986) have also published their own guides. The underlying problem which statistical process control ...

a method for predicting liquid densities of binary mixtures from heat of vaporization and liquid densityat boiling point temperature (δhvap and n b ρ ) as scaling constants, is presented. b2(t) follows a promisingcorresponding-states principle. calculation of α(t) and b(t), the two other temperature-dependentconstants of the equation of state, are made possible by scaling. as a result δhvap and...

in order to represent the potential energy function over the whole range of r, many potentialenergy functions have been proposed. in the present paper, we employ many potential energyfunctions, to use numerov method for solving the nuclear schrödinger equation for the ifmolecule, as an example of a heteronuclear diatomic molecules. then we determine thespectroscopic constants eω , e e x ω , e b...

in this paper we will prove that if $l$ is a continuous symmetric n-linear form on a hilbert spaceand $widehat{l}$ is the associated continuous n-homogeneous polynomial, then $||l||=||widehat{l}||$.for the proof we are using a classical generalized  inequality due to s. bernstein for entire functions of exponential type. furthermore we study the case that if x is a banach space then we have tha...

Two classical, damped and driven spin oscillators with an isotropic exchange interaction are considered. They represent a nontrivial physical system whose equations of motion are shown to allow for an analytic treatment of local codi-mension 1 and 2 bifurcations. In addition, numerical results are presented which exhibit a Feigenbaum route to chaos.

Remotely keyed encryption schemes (RKESs) support fast encryption and decryption using low-bandwidth devices, such as secure smartcards. The long-lived secret keys never leave the smartcard, but most of the encryption is done on a fast untrusted device, such as the smartcard’s host. This paper describes an new scheme, the length-preserving “accelerated remotely keyed” (ARK) encryption scheme an...

Analogy between an approximate version of Feigenbaum renormalization group analysis in complex domain and the phase transition theory of Yang-Lee (based on consideration of formally complexified thermodynamic values) is discussed. It is shown that the Julia sets of the renormal-ization transformation correspond to the approximation of Mandelbrot set of the original map. New aspects of analogy b...
