An accurate and cost-effective micro sun sensor based on the extraction of the sun vector using a phenomenon called the “black sun„ is presented.Unlike conventional image-based sun sensors where there is difficulty in accurately detecting the sun center, the black sun effect allows the sun center to be accurately extracted even with the
The phenomenon of glacial freezing and thawing involves microbial sequestration, release, and colonization, which has the potential to impact ecosystem functioning through changes in microbial diversity and interactions.In this study, we examined the structural features of microbial communities of the Dongkemadi glacier, including bacteria, fungi,
The survival of isolated small populations is threatened by both demographic and genetic factors.Large carnivores declined for centuries in most of Europe due to habitat changes, overhunting of their natural prey and direct persecution.However, the current rewilding trends are driving many carnivore populations to expand again, possibly reverting t
An artificial vision system is presented for lie detection by analyzing face thermal image sequences.This system represents an alternative technique to the polygraph.Some of its features are: 1) it has no physical Ball - Glove Softball Catcher - Junior contact with the examinee, 2) it is non-intrusive, 3) it has a potential for private use, and 4)
