There is an acknowledged growing need for efficient and sustainable systems that use available energy resources in an “optimal” (including constraints) way. Such a goal cannot be effectively achieved without taking into account the limits posed by the second law of thermodynamics. A possible...

Stepped wedge randomised trials are increasingly popular. Here we derive the optimal design for a fixed number of periods; this does not allocate an equal number of cluster units to each treatment sequence as might otherwise have been expected.

This article studies the semifoldover designs when initial designs are blocked regular designs. The properties and the structures of semifoldover blocked designs are investigated. Optimal blocking and semifoldover plans are tabulated for 16 and 32 run designs.

We present the leading hypotheses of a work in progress aiming at testing and comparing neural activities in the case of a cognitive illusion (the bat-and-ball illusion) and in the case of a typical instance of framing effects. We focus on contrasted answers linked to Stanovich's system 1 vs...
