Identifying and Analyzing Safety Critical Maneuvers from High Resolution AIS Data
Identifying and Analyzing Safety Critial Maneuvers.. [Link to article] ABSTRACT: We demonstrate the value in previously disregarded parameters in AIS data, and present a novel way of quickly identifying and characterizing potentially safety critical situations for vessels with a properly configured AIS transponder. The traditional approach of studying (near) collision situations, is through vessel conflict…
Electric Alignment of Plate Shaped Clay Aggregates in Oils
Published in Frontiers in Physics [Local cached copy] Abstract: We experimentally investigate the rotation of plate shaped aggregates of clay mineral particles immersed in silicone oil. The rotation is induced by an external electric field. The rotation time is measured as a function of the following parameters: electric field strength, the plate geometry (length and width)…
Venus Transit 06 June 2012
To my horror when i got up at 04:49 the sky was completely clouded, and thought that this once in a lifetime opportunity had passed. Fortunately an hour later it was good enough to see the transit. And then final contact at around 06:51. The transit of venus, from sunrise, around 04:34 to last contact…
Solar Panel angle
As we have added solar power to our cabin, i got interested in what would be the optimum angle of the solar panels to the sun. Right now they are mounted facing south at 90 degrees to the horizon. Not very good for summer weather. After a bit of searching i found a couple of…
Bold theta in latex
I had issues trying to get theta to be a bold symbol in latex, niether \bf or \mathbf seemed to work. Searching the internet gave no real solutions but after asking a cooluge he proposed i use: [code lang=”latex”] \include{amsmath} \newcommand{\boldtheta}{\boldsymbol \theta} \vec{\theta}=\boldtheta [/code] From=To
Isfjord Svalbard July 2011
This spectacular view was presented to us after a short hike up fuglefjellet along with a guide and balder (the dog carrying our coffee).
Lunar eclipse of 2008 as seen from Asker
My first attempt at photographing a lunar eclipse, there is quite a bit of overexposure, and it could have been done with a slightly better focus.
