2) average velocity ratio 平均波速比(Vp/Vs)3) average wave velocity 平均波速 1. Stress wave velocity of the concrete in a stake is discussed,and the method to determine the average wave velocity of a stake in building plot is proposed in the study. 通过对桩身混凝土中应力波波速的讨论...
Alternative LTV to CAC Calculation Example What is LTV/CAC? The LTV/CAC Ratio measures the relationship between the lifetime value of a customer and the cost incurred to acquire that customer. The customer lifetime value (LTV) refers to the profit attributable to a particular customer, while...
The LF/HF ratio has been suggested to be an accurate measure of the entire sympathovagal balance of the autonomic nervous system in which higher values indicate a more sympathetically compelled cardiovascular system. From: Smart Healthcare for Disease Diagnosis and Prevention, 2020 ...
to predict the total deformations of a construction assuming it is made from an ideally elastic material. This paper presents the effect of the load level at the values of the residual strains for beams made of high-strength concretes and subjected to bending. The investigations showed that the...
Finally, when the shear layers meet, the turbulence starts to decay and the velocity recovers. Depending on the distance from the wind turbine, the turbulence may therefore be very different. Here, the evolution of the wind turbine wake depends on the inflow conditions and the turbine operation...
Between two stations, a train accelerates from rest uniformly at first, then moves with constant velocity, and finally retards uniformly to come to rest. If the ratio of the time taken is 1:8:1 and the maximum speed attained be 60km/hr, then what is the average speed over the whole ...
