Birds are among the best-studied animal groups, but their prehistoric diversity is poorly known due to low fossilization potential. Hence, while many human-driven bird extinctions (i.e., extinctions caused directly by human activities such as hunting, as
Craig A. Kluever, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 I.C Kepler's Equation One can compute the time of flight between two arbitrary positions in an elliptical orbit using Kepler's second law if the area swept out by the radius vector can be calculated....
cathode-ray tube display for recording the true motion tracks of the ship and of other objects in its vicinity such that the recorded images of stationary objects are stationary relative to the record sheet. In producing such a record the record sheet may be orientated so that a vector on ...
Ku-band drive amplification and a 7-bit true-time-delay (TTD) function were realized as a part of a LTCC-based T/R module to increase integration. The 8-channel T/R module was fabricated and its key characteristics were measured, including a 3-bit (1/2/4
For the case of planar interception, the so called relative heading error angle between the relative velocity vector and the LoS (Line of Sight) is chosen as the output to be controlled to zero. 针对平面拦截问题,选择导弹和目标之间的相对速度矢量与导弹-目标视线之间的夹角(称为相对航向误差角)作为...
However, it has been with the more recent development of photonic technologies and high-resolution lithography that SWG structures have seen widespread application in integrated photonics in SOI. SWGs are normally classi- fied into structures that are arranged crosswise or lengthwise relative to the ...
Finally, in order to fix on the position of nonzero lattice vector effectively, that is, to deal with zero lattice vectors effectively, the concept of significant map is introduced into. 最后为了有效确定非零格点的位置,也就是为了有效地处理零格点,又引进了重要图的概念。 28. 48kb This paper...
If each patch size is set to 4 × 4 and considering the three channels (R, G, B), each patch, after undergoing linear embedding, results in a feature vector of dimensions 4 × 4 × 3 = 48. Figure 6. Swin-Unet network model architecture. Swin-Unet is organized as a four-level ...

There are also tools related to constrainted optimization and image processing. Typically these are utility functions that are not stand alone applications. Here's an incomplete list of cool features this matlab toolbox contains: - wrappers for TetGen, Triangle, QSlim, meshfix - mesh smoothing ...
