A recent proposal for a classroom experiment to estimate the speed of light using a networked computer relies upon some special hardware and Linux machines able to measure the time-of-flight to the nearest micro
Rømer used his observations to estimate the speed of light. Since the size of the solar system and Earth's orbit wasn't yet accurately known, argued a 1998 paper in theAmerican Journal of Physics, he was a bit off. But at last, scientists had a number to work with. Rømer's calc...

Finally, standard population decoding of these speed-selective units yields precise, unbiased, optimal speed estimates (given the front-end constraints and optimal linear RFs). Figure 1: Ideal observer analysis. The task is to obtain the most accurate estimate of some property of the environment, ...
To calculate the potential wind loading on a tall building in an urban area, an accurate representation of the wind speed profile is required. However, due to a lack of observations, wind engineers typically estimate the characteristics of the urban boundary layer by translating the measurements fr...
(see methods). We estimateη ≈ 0.885 from available data (95% CI [0.879; 0.890]), which corresponds tou = (1−η)−1 = 8.69 (95% CI [8.26; 9.09]), in robust agreement with the fitted estimate. We conclude that the prediction of the maximum running speed enabled ...
estimate the corresponding offset, for example { x center offset , y center offset , w offset , h offset } and { x top left offset , y top left offset , x bottom right offset , y bottom right offset } . However, to directly estimate the coordinate values of each point of the B...
Their results showed that the same motion signals were used differently: to estimate the speed of the pursuit target for a perceptual judgment, context motion was subtracted from the pursuit target motion; to calculate the velocity for the pursuit response to follow the target, both, context ...
An overview of the method of validating walking speed can be viewed in Fig.1. Figure 1 Overview of (a) the TVS protocol, (b) the analytical pipeline applied to estimate walking speed from the wearable device data (WD), (c) the approach to validating walking speed estimated from the analy...
Speed prediction aims to estimate the speed of traffic participants in a future period based on current and historical traffic states. Meanwhile, prediction can be classified into three categories according to the different scales, i.e., traffic speed prediction (macro), vehicle speed prediction (mi...
