在日常用语中，这两个词没有区别，可以通用。而在物理学里，velocity 是一个矢量(vector quantity)表示起点与终点间直线距离的长度除以所用时间所得的量，并注明方向：而 speed 是一个数量(scalar quantity)，是指起点到终点所走过的所有路程除以所用时间所得的量，且不标明方向。
Here we first analyse natural image movies to determine the optimal space-time receptive fields (RFs) for encoding local motion speed in a particular direction, given the constraints of the early visual system. Next, from the RF responses to natural stimuli, we determine the neural computations ...

In particular, theoretical work has emphasized a fundamental distinction between decisions about movement direction and decisions about movement timing. These two types of decision are expected to have different distributions of consensus costs, leading to contrasting predictions about whether they are ...
DOOR, IN PARTICULAR A HIGH-SPEED DOORThe invention relates to a door having a door leaf (1) with a vertical running direction and a drive (7) for opening and closing the door. A brake device (8) is provided, which is designed in such a way that the door leaf (1) can be moved ...
In the Fig. 3 we present the speed up as a function of the number of processor used to solve the problem. The Fig. 3 shows the speed up which is obtain in the case of domain decomposition in x direction. We note that the efficiency of our method in that case decrease when more ...
The sign of the angular frequency (the sign of ω) indicates the rotation direction; e.g. when ω>0 the vector rotates counterclockwise and when ω<0 the vector rotates clockwise with time. Due to the envelope variation in time the phasor velocity has also a radial component along the ...
39 have shown that this particular system has an accuracy of 9 cm (root mean square error, RMSE) when compared to a VICON motion capture system used as a reference40. With regard to the speed, the accuracy was 0.09 m/s (RMSE), being more accurate in the detection of high-speeds39. ...
We introduce a deep learning framework able to deal with strong privacy constraints. Based on collaborative learning, differential privacy and homomorphic encryption, the proposed approach advances state-of-the-art of private deep learning against a wider range of threats, in particular the honest-but...
