Schneefernerhaus as a mountain research station for clouds and turbulence [PDF]
Atmospheric Measurement Techniques, 2015 Cloud measurements are usually carried out with airborne campaigns, which are expensive and are limited by temporal duration and weather conditions. Ground-based measurements at high-altitude research stations therefore play a complementary role in cloud

A Robust Photogrammetric Processing Method of Low-Altitude UAV Images
Remote Sensing, 2015 Low-altitude Unmanned Aerial Vehicles (UAV) images which include distortion, illumination variance, and large rotation angles are facing multiple challenges of image orientation and image processing. In this paper, a robust and convenient photogrammetric

Shortest closed billiard orbits on convex tables [PDF]
, 2014 Given a planar compact convex billiard table $T$, we give an algorithm to find the shortest generalised closed billiard orbits on $T$. (Generalised billiard orbits are usual billiard orbits if $T$ has smooth boundary.) This algorithm is finite if $T$ is ...

The anthropogenic contribution to atmospheric black carbon concentrations in southern Africa: a WRF-Chem modeling study [PDF]
Atmospheric Chemistry and Physics, 2015 South Africa has one of the largest industrialized economies in Africa. Emissions of air pollutants are particularly high in the Johannesburg-Pretoria metropolitan area, the Mpumalanga Highveld and the Vaal Triangle, resulting in local air pollution ...

Equicevian points on the altitudes of a triangle
Elemente der Mathematik, 2012 Let \(ABC\) be a triangle. Consider a point \(P\neq B\) a point in the plane containing \(ABC\) such that \(BP\) is not parallel to \(AC\). We denote (it it exists) by \(BB_P\) the cevian from \(B\) through \(P\). In the same way, if \(P\neq C\) and \(CP\) is not parallel to \(AB\), we could define \(CC_P\).

A Fuzzy Logic Based Algorithm for Finding Astronomical Objects in Wide-Angle Frames [PDF]
, 2005 Accurate automatic identification of astronomical objects in an imperfect world of non-linear wide-angle optics, imperfect optics, inaccurately pointed telescopes, and defect-ridden cameras is not always a trivial first step.
