Inferring proximity from Bluetooth Low Energy RSSI with Unscented Kalman Smoothers
Tom Lovett, Mark Briers, Marcos Charalambides +3
The Covid-19 pandemic has resulted in a variety of approaches for managing infection outbreaks in international populations. One example is mobile phone applications, which attempt…
Risk scoring calculation for the current NHSx contact tracing app
Mark Briers, Marcos Charalambides, Chris Holmes
We consider how the NHS COVID-19 application will initially calculate a risk score for an individual based on their recent contact with people who report that they have coronavirus…
Distinct Distances on Curves via Rigidity
Marcos Charalambides
It is shown that points on a real algebraic curve of degree in always determine distinct distances, unless the curve is a st…
A note on distinct distance subsets
Marcos Charalambides
It is shown that given a set of points in the plane or on the sphere, there is a subset of size with all pairwise distances between points distinct.
On Restricting Cauchy-Pexider Equations to Submanifolds
Marcos Charalambides
Sufficient geometric conditions are given which determine when the Cauchy-Pexider functional equation f(x)g(y)=h(x+y) restricted to x,y lying on a hypersurface in R^d has only solu…
Near-extremizers of Young's inequality for discrete groups
Marcos Charalambides, Michael Christ
Those functions which nearly extremize Young's convolution inequality are characterized for discrete groups which have no nontrivial finite subgroups. Near-extremizers of the Hausd…
