Optimization-based tuning of low bandwidth control in spatially distributed systems
Low bandwidth controller controller filter control signal robust
2015/8/11
We describe a new method for tuning a certain family of low-bandwidth controllers for linear time-invariant and spatially-invariant (LTSI) plants. We consider LTSI controllers with a fixed structure, ...
Bypassing the bandwidth theorem with PT symmetry
Bypassing the bandwidth theorem PT symmetry Classical Physics
2012/5/29
The beat time {\tau}_{fpt} associated with the energy transfer between two coupled oscillators is dictated by the bandwidth theorem which sets a lower bound {\tau}_{fpt}\sim 1/{\delta}{\omega}. We sho...
Spectral Bandwidth Reduction of Thomson Scattered Light by Pulse Chirping
Spectral Bandwidth Reduction of Thomson Light Pulse Chirping Optics
2012/4/19
Based on single particle tracking in the framework of classical Thomson scattering with incoherent superposition, we developed a fully relativistic, three dimensional numerical code that calculates an...
25 kHz narrow spectral bandwidth of a wavelength tunable diode laser with a short waveguide-based external cavity
25 kHz narrow spectral bandwidth wavelength tunable diode laser short waveguide-based external cavity Optics
2012/4/19
We report on the spectral properties of a diode laser with a tunable external cavity in integrated optics. Even though the external cavity is short compared to other small-bandwidth external cavity la...
High Bandwidth Pickup Design for Bunch Arrival-time Monitors for Free-Electron Laser
High Bandwidth Pickup Design Bunch Arrival-time Monitors Free-Electron Laser
2012/2/29
In this paper, we present the design and realization of high bandwidth pickup electrodes with a cutoff frequency above 40 GHz. The proposed cone-shaped pickups are part of a bunch arrival-time monitor...

Distributed Storage Codes with Repair-by-Transfer and Non-achievability of Interior Points on the Storage-Bandwidth Tradeoff
Repair-by-Transfer Non-achievability Interior Points Storage-Bandwidth Tradeoff
2010/11/17
Regenerating codes are a class of recently developed codes for distributed storage that, like Reed-Solomon codes, permit data recovery from any subset of k nodes within the n-node network. However, r...
Bandwidth selection in kernel density estimation: oracle inequalities and adaptive minimax optimality
density estimation kernel estimators Lp–risk oracle inequalities adaptive estimation
2010/11/30
We address the problem of density estimation with L p–loss by selection of kernel estimators. We develop a selection procedure and derive corresponiding L p–risk oracle inequalities. It is shown that ...
Bandwidth allocation and QoS routing for heterogeneous networks
bandwidth allocation QoS routing blocking probability
2010/9/16
We present a bandwidth allocation scheme offering optimal solutions to the network optimization problem. The bandwidth allocation policy in class-based networks can be defined with the proportionally ...
A new t-out-n oblivious transfer with low bandwidth
Two-lock cryptosystem private information retrieval elliptic curve
2010/9/15
The most efficient previously proposed oblivious transfer schemes require t calls of 1-out-n oblivious transfer (OT) to construct the t-out-n OT. Its computational requirements and bandwidth consumpti...
THE CYCLIC BANDWIDTH PROBLEM
2007/8/7
The cyclic bandwidth problem for a graph G is to label its n venices by the elements of the additive group (Z_n,\oplus) of integers modulo n so that the quantity max{d(f(u), f(v)): (u,v) ∈E(G)} is min...
