The classical Poisson functor associates to every infinite measure preserving dynamical system (X, μ, T) a probability (X*, μ*, T*) called the suspension of T. In this paper we generalize construction: subgroup Aut2(X, μ) μ-nonsingular transformations T X is specified as largest for which T* μ*-nonsingular. topological structure studied. We show that generic element in ergodic and Krieger type ...

A method is described for estimating the cell concentration of bacterial suspensions by measurement of the column lengths of packed cells centrifuged into a capillary tube of fine bore. The total error, under the experimental conditions employed, checked by direct count, was >2 per cent for dense suspensions and about 5 per cent for light suspensions. The method is suitable for work requiring r...

This paper takes as its catalyst a series of live art events that took place between London and Manchester in 2019. Thinking conversation with Erin Manning’s propositions for “minor movements” the Duchampian “infrathin”, we explore potential to temporarily suspend thresholds perceptibility permissibility public realm. We argue artful techniques improvisation carry capitalistic orderings time by...

This paper presents a new LPV/H∞ semi-active suspension control strategy for a commercial vehicle equipped with 4 Magneto-Rheological dampers. The proposed approach concerns road adaptation using on-line road profile identification based on a non linear algebraic observer with unknown input. Then, the suspensions forces distribution in each corner of vehicle is performed considering roll dynami...

We introduce the (2+1)-spacetimes with compact space of genus g ≥ 0 and r gravitating particles which arise by Minkowskian suspensions of flat or hyperbolic cone surfaces, by distinguished deformations of hyperbolic suspensions and by patchworking of suspensions. Similarly to the matter-free case, these spacetimes have nice properties with respect to the canonical Cosmological Time Function. Wh...
