Recent statistical methods for orientation data

The application of statistical methods for determining the areas of animal orientation and navigation are discussed. The method employed is limited to the two-dimensional case. Various tests for determining the validity of the statistical analysis are presented. Mathematical models are included to support the theoretical considerations and tables of data are developed to show the value of information obtained by statistical analysis

A Refined route-to-market strategy for ERBE in South Korea

CEMSERBE is a German manufacturer of medical devices operating in South Korea since 2005. However, since 2011 revenues in the South Korean market have been decreasing, despite overall market growth. As such, this Work Project, based on the CEMS MIM business project developed with ERBE, focuses on recommending a “Refined route-to-market Strategy for ERBE in South Korea” in order to enhance growth. This new strategy relies on three key aspects: adopting a multi-distributor approach, enhancing distributors’ motivation and fostering relationships with customer

Development of lateralization of the magnetic compass in a migratory bird

The magnetic compass of a migratory bird, the European robin (Erithacus rubecula), was shown to be lateralized in favour of the right eye/left brain hemisphere. However, this seems to be a property of the avian magnetic compass that is not present from the beginning, but develops only as the birds grow older. During first migration in autumn, juvenile robins can orient by their magnetic compass with their right as well as with their left eye. In the following spring, however, the magnetic compass is already lateralized, but this lateralization is still flexible: it could be removed by covering the right eye for 6 h. During the following autumn migration, the lateralization becomes more strongly fixed, with a 6 h occlusion of the right eye no longer having an effect. This change from a bilateral to a lateralized magnetic compass appears to be a maturation process, the first such case known so far in birds. Because both eyes mediate identical information about the geomagnetic field, brain asymmetry for the magnetic compass could increase efficiency by setting the other hemisphere free for other processes

A Cartesian co-ordinate system for representing the second to fifth metacarpals in the human hand

Description: This is tha authors' PDF version of an article published in Radiography© 2004. The definitive version is available at www.elsevierhealth.comPurpose The use of hand radiographs has both clinical and anthropometric applications. However, a method for converting standard bony points within the metacarpus to Cartesian co-ordinates does not exist. Methods A simple method for converting standard bony points of the second to fifth metacarpals to Cartesian co-ordinates is described for the first time. Results Using a small set of measurements and treating these with equations of known voracity, this method is accurate and allows the metacarpus to be interro¬gated via a much wider range of geometrical techniques than has so far been available. Conclusions This method allows naked-eye assessments to be supported or re¬placed by metrical evaluations. It is likely to have both clinical and anthropometric uses.University of Liverpool research development grant

Numerical exploration of a hexagonal string billiard

In this paper we are interested in the motion of a ball inside a billiard table bounded by a particular smooth curve. This table belongs to a family of billiards which can all be drawn by a common process: the so-called gardener's string construction. The classical elliptical billiard is, of course, the foremost member of this family. So it should come as no surprise that our hexagonal string billiard shares many basic properties with the latter, but, on the other hand, also exhibits some essential differences with it. We have gathered numerical evidence against the Birkhoff-Poritsky conjecture.Comment: Preprint, 30 pages, 26 figure
