AIMD algorithms and exponential functionals
- Ann. Appl. Probab
, 2002
"... ABSTRACT. The behavior of connection transmitting packets into a network according to a general additive-increase multiplicative-decrease (AIMD) algorithm is investigated. It is assumed that loss of packets occurs in clumps. When a packet is lost, a certain number of subsequent packets are also lost ..."

On Randomized Network Coding
- In Proceedings of 41st Annual Allerton Conference on Communication, Control, and Computing
, 2003
"... We consider a randomized network coding approach for multicasting from several sources over a network, in which nodes independently and randomly select linear mappings from inputs onto output links over some field. This approach was first described in [3], which gave, for acyclic delay-free netwo ..."

-free networks, a bound on error probability, in terms of the number of receivers and random coding output links, that decreases exponentially with code length. The proof was based on a result in [2] relating algebraic network coding to network flows. In this paper, we generalize these results to networks
On recurrence coefficients for rapidly decreasing exponential weights

"... Abstract. Let, for example, W (x) = exp exp k 1 x 2, x 2 [ 1; 1] where> 0, k 1; and exp k = exp (exp (::: exp ())) denotes the kth iterated exponential. Let fAng denote the recurrence coe ¢-cients in the recurrence relation xpn (x) = Anpn+1 (x) + An 1pn 1 (x) for the orthonormal polynomials fpn ..."

Exponential grids in high-dimensional space
, 2011
"... We consider the approximation of functions that are localized in space. We show that it is possible to define meshes to approximate such functions with the property that the number of vertices grows only linearly in dimension. In one dimension, we discuss the optimal mesh for approximating exponenti ..."

exponentially decreasing functions. We review the use of Cartesian product grids in multiple dimensions introduced in a paper of Bank and Scott [4].
Proactive Serving Decreases User Delay Exponentially
"... In online service systems, the delay experienced by a user from the service request to the service completion is one of the most critical performance metrics. To improve user de-lay experience, recent industrial practice suggests a modern system design mechanism: proactive serving, where the sys-tem ..."

-tem predicts future user requests and allocates its capacity to serve these upcoming requests proactively. In this pa-per, we investigate the fundamentals of proactive serving from a theoretical perspective. In particular, we show that proactive serving decreases average delay exponentially (as a function
Comparing elliptic curve cryptography and RSA on 8bit CPUs
- in Proc. of the Sixth Workshop on Crypto- graphic Hardware and Embedded Systems (CHES’04
, 2004
"... Abstract. Strong public-key cryptography is often considered to be too computationally expensive for small devices if not accelerated by crypto-graphic hardware. We revisited this statement and implemented elliptic curve point multiplication for 160-bit, 192-bit, and 224-bit NIST/SECG curves over GF ..."

hardware acceleration. On an Atmel ATmega128 at 8 MHz we measured 0.81s for 160-bit ECC point multiplication and 0.43s for a RSA-1024 operation with exponent e = 216 +1. 2. The relative performance advantage of ECC point multi-plication over RSA modular exponentiation increases with the decrease
The ultra-wide bandwidth indoor channel: from statistical model to simulations
- IEEE J. SEL. AREAS COMMUN
, 2002
"... We establish a statistical model for the ultra-wide bandwidth (UWB) indoor channel based on an extensive measurement campaign in a typical modern office building with 2-ns delay resolution. The approach is based on the investigation of the statistical properties of the multipath profiles measured i ..."

The averaged power delay profile can be well-modeled by a single exponential decay with a statistically distributed decay constant. The small
Fixed energy inverse problem for exponentially decaying potentials

This result has been proved by Novikov previously [4], see also [3], using a ∂-equation. We present a different method, which combines a density argum ..."

Behavioral theories and the neurophysiology of reward,
- Annu. Rev. Psychol.
, 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."
