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 microsecond. At first sight, ordinary PCs running Windows appear not to be capable of ...
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...
separately in Sections “An Eckart barrier” and “An Eckart well”, respectively. In Section “Is there an effective range of spatial delays?” we ask whether one can define an “effective range” of the delays, and answer the question in the negative. Section “Spatial delays vs. detection...
A robust validation of walking speed therefore requires analysis of the estimate of walking speed at a walking bout (WB) level from the implementation of the full pipeline. The aim of this study was to provide a comprehensive validation of walking speed estimated from a single inertial measurement...
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...
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...
A robust method to estimate the maximal Lyapunov exponent of a time series A very simple method to compute the maximal Lyapunov exponent of a time series is introduced. The algorithm makes use of the statistical properties of the ... H Kantz - 《Physics Letters A》 被引量: 977发表: 1994...
“above-the-fold threshold” and defers all styles for elements below the fold. However, this threshold is just an estimate and can vary on different devices. Increasing threshold height will defer fewer styles, resulting in slightly slower load times but less of a chance for Cumulative Layout...
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, ...
Since it was first introduced by the laboratories of Heintzmannl1 and Gustafsson2 two decades ago, SIM has been evolving constantly to improve speed, resolution, and to decrease the required light dosages. Reconstruction algorithms have been developed to estimate microscope parameters robustly3, ...
