There is a theory that it comes from the World War II RAF acronym GISS for "General Impression of Size and Shape (of an aircraft)", [11] but the use of the term in 1922 precludes that. [ 7 ] [ 12 ] Another theory is that jizz is a corruption of gestalt , a German word that roughly means form or shape. [ 13 ]
Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The variation in dimensions and weights across birds is one of the fundamental sources of diversity among birds, and even Within species, dimensions may vary across populations within species , between the sexes and depending on age and ...
The app allows users to create and edit flowcharts, organisational charts, website wireframes, mind maps, concept maps, and other types of diagrams online while collaborating with other users in real-time. It allows importing images from the computer or from the Web as well as inserting shapes, arrows, scribbles and text from predefined templates.
U.S. birds display a wide array of striking hues. But just how colorful are our American birds? What you need to know from our study.
This method translates the centroid of the shapes to (0,0); the x coordinate of the centroid is the average of the x coordinates of the landmarks, and the y coordinate of the centroid is the average of the y-coordinates. Shapes are scaled to unit centroid size, which is the square root of the summed squared distances of each landmark to the ...
There are three main types of computer environments for studying school geometry: supposers [vague], dynamic geometry environments (DGEs) and Logo-based programs. [2] Most are DGEs: software that allows the user to manipulate ("drag") the geometric object into different shapes or positions.

The majority of this length is due to the hummingbird's extreme tail streamers. Another size champion among hummingbirds is the sword-billed hummingbird, a fairly large species of which approximately half of its 21 cm (8.3 in) length derives from its bill. This is by far the largest bill-to-body-size ratio of any bird. [66]
