Dew point measurement using a sensitive circuit type of dew point sensor

Received: 13 Mar. 2012; Revised 25 Jul. 2012; Accepted 04 Aug. 2012 Received: April 8, 2012; Revised May 4, 2012; Accepted June 6, 2012 Abstract: Aiming at the problem of atmospheric humidity measurement, this paper proposes a method to measure dew point based on sensitive circuit for the first time. We use the quartz crystal in the Colpitts circuit as the humidity sensitive element. Since the ...

On polygons enclosing point sets

Let R and B be disjoint point sets such that R ∪ B is in general position. We say that B is enclosed by R if there is a simple polygon P with vertex set R such that all the elements in B belong to the interior of P . In this paper we prove that if the vertices of the convex hull of R ∪B belong to B, and |R| ≤ |Conv(R)| − 1 then B encloses R. The bound is tight. This improves on results of a pre...

Coronal Temperature as an Age Indicator

The X-ray spectra of late type stars can generally be well fitted by a two temperature component model of the corona. We find that the temperatures of both components are strong functions of stellar age, although the temperature of the hotter plasma in the corona shows a larger scatter and is probably affected by the activity of stars, such as flares. We confirm the power-law decay of the tempe...
