Crow Terminological Scales: Corrections

Comparative phylogeography of two crow species: jungle crow Corvus macrorhynchos and carrion crow Corvus corone.

The jungle crow Corvus macrorhynchos Wagler, 1827, and the carrion crow Corvus corone L., 1758, are two closely related species with similar ecological requirements that occupy wide distribution ranges in the Palearctic. We studied patterns of their genetic variation by using sequences of the mitochondrial cytochrome b gene. Corvus macrorhynchos demonstrates a low level of variation and differe...

An Empirical Analysis of Terminological Representation Systems Terminological Representation Systems

The family of terminological representation systems has its roots in the representation system kl-one. Since the development of kl-one more than a dozen similar representation systems have been developed by various research groups. These systems vary along a number of dimensions. In this paper, we present the results of an empirical analysis of six such systems. Surprisingly, the systems turned...

Automating the Purple Crow Lidar

The Purple Crow LiDAR (PCL) was built to measure short and long term coupling between the lower, middle, and upper atmosphere. The initial component of my MSc. project is to automate two key elements of the PCL: the rotating liquid mercury mirror and the Zaber alignment mirror. In addition to the automation of the Zaber alignment mirror, it is also necessary to describe the mirror’s movement an...

years, like Lake Vostok, underneath the eponymous Russian research station at 77 degrees South. One of the largest lakes on our planet, Lake Vostok is comparable in volume to Lake Ontario. Back in 1998, a research team drilled around three kilometres deep into the ice shield stopping only a few hundred metres above the lake surface. The lower parts of the ice core, believed to consist of frozen...
