چکیده
An economical and effective method to measure displacement is integrate the acceleration signal. Because of zero drift in sensor, there will be a trend term process secondary integration, which cause some errors measurement. In this paper, several methods signal processing with are given, advantages disadvantages these as well applicable occasions analysed, have important reference value for selecting reasonable dealing engineering problems.

Estimating the inter-story drift in high rise buildings with the flexural and shear cantilever beam and mode-acceleration method
In this study, the seismic inter-story drift of structures is estimated by a combination of mode-acceleration equations with the modelling of high-rise buildings with flexural and shear cantilever beams. In the equation presented for calculating the inter-story drift, having less knowledge of the building is adequate and this issue is of significance in estimating the nonstructural component fo...

برای پردازش سیگنال آنالوگ در شبکه های عصبی ، معمولا نیاز به یک واحد حافظه آنالوگ احساس میشود که بدون احتیاج به a/d وd/a بتواند بطور قابل انعطاف و مطمئن اطلاعات آنالوگ را در خود ذخیره کند. این واحد حافظه باید دارای دقت کافی ، سرعت بالا ، توان تلفاتی کم و سایز کوچک باشد و همچنین اطلاعات را برای زمان کافی در خود نگهدارد. برای پیاده سازی سیستمی که همه این قابلیتها را در خود داشته باشد، کوشش...
15 صفحه اولAcceleration of acoustic emission signal processing algorithms using CUDA standard
Offline processing of acoustic emission (AE) signal waveforms recorded during a long-term AE monitoring session is a challenging problem in AE testing area. This is due to the fact that today’s AE systems can work with up to hundreds of channels and are able to process tens of thousands of AE events per second. The amount of data recorded during the session is very high. This paper proposes a w...
متن کاملCompensating frequency drift in DPSK systems via baseband signal processing
A new baseband signal processing method for compensating frequency shift in differential phase-shift keying (DPSK) systems is introduced. This method consists of a signal processor for the initial acquisition of frequency shift and a simple adaptive equalizer for tracking. The former is based on the observation that the effect of frequency shift can be eliminated by using boundary values of the...

τ∗ = inf { t ∈ [0, T ] | B t ≤ b−(t) or B t ≥ b+(t) } where the function t 7→ b−(t) is continuous and increasing on [0, T ] with b−(T ) = 0 , the function t 7→ b+(t) is continuous and decreasing on [0, T ] with b+(T ) = 0 , and the pair b− and b+ can be characterised as the unique solution to a coupled system of nonlinear Volterra integral equations. This also yields an explicit formula for V∗ ...
