Optimal Aggregation of Consumer Ratings: An Application to Yelp.com
crowdsourcing social network e-commerce
font style='font-size:12px;'>
2015/9/21
Consumer review websites such as Yelp.com leverage the wisdom of the crowd, with
each product being reviewed many times (some with more than 1000 reviews). Because of
this, the way in which informat...
Optimal current waveforms for brushless permanent magnet motors
Permanent magnetic electric magnetic current waveform emf waveform voltage current limiting eddy current loss model
font style='font-size:12px;'>
2015/8/7
In this paper we give energy-optimal excitation current waveforms for a permanent magnet synchronous motor that result in a desired average torque. Our formulation generalizes previous work by includi...

2012/4/20
The bang-bang optimal control method was proposed for glow discharge plasma actuators, taking account of practical issues, such as limited actuation states with instantaneously varied aerodynamic cont...
Asymptotic behaviour and numerical approximation of optimal eigenvalues of the Robin Laplacian
Robin Laplacian Eigenvalues Optimisation
font style='font-size:12px;'>
2012/4/18
We consider the problem of minimising the $n^{th}-$eigenvalue of the Robin Laplacian in $\mathbb{R}^{N}$. Although for $n=1,2$ and a positive boundary parameter $\alpha$ it is known that the minimiser...
Optimal, scalable forward models for computing gravity anomalies
Optimal scalable forward models computing gravity anomalies
font style='font-size:12px;'>
2011/8/18
Abstract: We describe three approaches for computing a gravity signal from a density anomaly. The first approach consists of the classical "summation" technique, whilst the remaining two methods solve...
One parameter family of indecomposable optimal entanglement witnesses arising from generalized Choi maps

2011/10/8
Abstract: In the recent paper [Chru\'{s}ci\'{n}ski and Wudarski, arXiv:1105.4821], it was conjectured that the entanglement witnesses arising from some generalized Choi maps are optimal. We show that ...
