An inclined air-curtain (IAC) fume hood was developed and characterized using the laser-assisted smoke flow visualization technique and tracer-gas (sulphur hexafluoride) concentration detection method. The IAC fume hood features four innovative design elements: (i) an elongated suction slot installed at the hood roof with an offset towards the rear wall, (ii) an elongated up-blowing planar jet ...

To increase containment efficiency and reduce energy consumption, a sash-less, variable-height inclined air-curtain fume hood (sIAC hood) was developed and tested by a laser-assisted flow visualization technique and tracer-gas detection method. This novel design requires neither sash nor baffle. The sIAC hood employed the inclined push-pull air-curtain technique and two deflection plates instal...

An M x n matrix C is called Mange matrix if c,, + cTT < clr + cr, for all 1 < i -c r < rn, 1 < j < s d n. In this paper we present a survey on Monge matrices and related Monge properties and their role in combinatorial optimization. Specifically, we deal with the following three main topics: (i) fundamental combinatorial properties of Monge structures, (ii) applications of Monge properties to o...

We consider right-continuous peacocks, that is families of real probability measures (μt)t that increase in the convex order. Given a sequence of time partitions we associate the sequence of martingales that are Markovian, constant on the partition intervals [tk, tk+1[, and designed in a way that the transition kernels at times tk+1 are the curtain couplings of marginals μtk and μtk+1 . We stud...
