Since GPS signals are unavailable for indoor navigation, current research mainly focuses on vision-based locating with a single mark. An obvious disadvantage with this approach is that locating will fail when the mark cannot be seen. The use of multiple marks can solve this problem. However, the extra process to design and identify different marks will significantly increase system complexity. In this paper, a novel vision-based locating method is proposed by using marks with feature points arra...

For more than 1,000 years there have been relations between Denmark and Russia in political, cultural and economic affairs. There has never been a real bilateral war between the two countries. However, it is not said that the relationship has always been harmonious or close, neither in state nor in popular terms. 525 years ago, in the year 1493, the Danish-Russian relations were finally written down in the so-called Treaty of Copenhagen on the 8th of November. Since then diplomatic relations bet...

<p>Abstract</p> <p>Background</p> <p>The origin and evolution of viruses is currently a heavily discussed issue. One element in this discussion is the innate viral "self" concept, which suggests that viral structures and functions can be divided into two categories. The first category consists of genetic determinants that are inherited from a viral ancestor and encode the viral "self". The second group consists of another set of structures and functions, the "nonself", which is interchangeable b...

Aquatic macrophytes constitute important components of many freshwater ecosystems. The manifold role of aquatic macrophytes in freshwater habitats is closely linked to their distribution, which in turn depends on a myriad of factors. Foremost, among these are light, water temperature, water quality changes and nutrient enrichment, sediment composition and fluctuations in water levels. Light and temperature are of paramount importance in determining the distribution (with depth, season and latitu...
