Recirculating apparatus for testing hygrometers

Self testing quantum apparatus

We study, in the context of quantum information and quantum communication, a configuration of devices that includes (1) a source of some unknown bipartite quantum state that is claimed to be the Bell state Φ and (2) two spatially separated but otherwise unknown measurement apparatus, one on each side, that are each claimed to execute an orthogonal measurement at an angle θ ∈ {−π/8, 0, π/8} that...

An apparatus for pseudo-deterministic testing

Pseudo-random testing is popularly used, particularly in Built-In Self Test (BIST) applications. To achieve a desired fault coverage, pseudo-random patterns are often supplemented with few deterministic patterns. When positions of deterministic patterns in the pseudo-random sequence are known a priori, pseudo-random sub-sequences can be chosen such that they cover these deterministic patterns. ...

Recirculating systems for zebrafish.

In the past several years, zebrafish [Danio rerio] have emerged as a very important model for embryological, neurological, and genetics research. Scientists are using this tiny tropical freshwater fish as a biological model because of its quick generation time, high fecundity, and transparent eggs. The emergence of zebrafish in a growing number of research laboratories has brought about a new b...

Construction Material Monitoring with «optical Hair» Hygrometers

Evaporative microclimate driven hygrometers and hygromotors

A strip of paper placed on a hand spontaneously curls upwards. This simple observation illustrates the ability of a relatively homogeneous hygroscopic structural material, paper, to sense and respond to the microclimate near a non-equilibrium system, a moist evaporative boundary layer. We quantify this interaction using a simple experiment and show that it can be understood in terms of a minima...
