R software: unfriendly but probably the best

Probably the best simple PID tuning rules in the world

The aim of this paper is to present analytic tuning rules which are as simple as possible and still result in a good closed-loop behavior. The starting point has been the IMC PID tuning rules of Rivera, Morari and Skogestad (1986) which have achieved widespread industrial acceptance. The integral term has been modified to improve disturbance rejection for integrating processes. Furthermore, rat...

Unfriendly fumes.

Background: As every healthcare intervention carries some risk of harm, clinical decision making needs to be supported by a systematic assessment of the balance of benefit to harm. A systematic review that considers only the favourable outcomes of an intervention, without also assessing the adverse effects, can mislead by introducing a bias favouring the intervention. Much of the current guidan...

RED+ Gateways for Identification and Discrimination of Unfriendly Best-Effort Flows in the Internet

This paper proposes an add-on to the well known RED (Random Early Detection) algorithm called RED+. RED+ adds the functionality of identifying and discriminating high-bandwidth, unfriendly best-effort flows to RED gateways. It is based on the observation that unfriendly flows have higher arrival rates in times of congestion than friendly flows. Hence unfriendly flows can be discriminated if pac...

Measure-theoretic unfriendly colorings

We consider the problem of finding a measurable unfriendly partition of the vertex set of a locally finite Borel graph on standard probability space. After isolating a sufficient condition for the existence of such a partition, we show how it settles the dynamical analog of the problem (up to weak equivalence) for graphs induced by free, measurepreserving actions of groups with designated finit...
