  • 機(jī)電類(lèi)比法在傳感器中的相關(guān)分析

    機(jī)電類(lèi)比法是一種把機(jī)械量通過(guò)一定的計(jì)算等效類(lèi)比為電量的方法,其在對(duì)電子機(jī)械系統(tǒng)的分析中應(yīng)用非常廣泛。它能夠把一個(gè)較復(fù)雜的機(jī)械系統(tǒng)類(lèi)比為我們熟知的電路系統(tǒng)來(lái)進(jìn)行分析,從而使問(wèn)題的分析得到簡(jiǎn)化。本文通過(guò)對(duì)振弦式傳感器的分析介紹了機(jī)電類(lèi)比法,并對(duì)使用電路進(jìn)行了相關(guān)的分析。 Summary:The electromechanical analogy is assort of analysis which is to analogize the mechanical system by using circuit system , it applied widely in the filed of analysis the electronic-mechanical system. The analysis can take a complex mechanical system analogous to a circuitry that we well-known, which can simplify the problems. In the paper, the electro-mechanical analogy method is briefly introduced by analysis the vibrating wire sensor,and have a correlation analysis about the circuit we used.關(guān)鍵詞: 機(jī)電類(lèi)比法  振弦式傳感器  頻率  振蕩  反饋Keyword:electro-mechanical analogy method,vibrating wire sensor,frequency,  oscillation, feedback 0  引言振弦式傳感器是屬于頻率式傳感器的一種。所謂頻率式傳感器就是能直接將被測(cè)量轉(zhuǎn)換為振動(dòng)頻率信號(hào)的傳感器,這類(lèi)傳感器一般是通過(guò)測(cè)量振弦、振筒、振梁、振膜等彈性振體或石英晶體諧振器的固有諧振頻率來(lái)達(dá)到測(cè)量引起諧振頻率變化的被測(cè)非電量的目的,其也稱為諧振式傳感器[1]。在分析該類(lèi)傳感器中,由于其涉及到頻率,就容易讓人聯(lián)想到在電子技術(shù)中接觸到的RLC振蕩電路。因此可以嘗試著用類(lèi)比的方法使之對(duì)應(yīng)起來(lái)分析,即機(jī)電類(lèi)比法分析。

  • LatentSVM論文

    The object detector described below has been initially proposed by P.F. Felzenszwalb in [Felzenszwalb2010]. It is based on a Dalal-Triggs detector that uses a single filter on histogram of oriented gradients (HOG) features to represent an object category. This detector uses a sliding window approach, where a filter is applied at all positions and scales of an image. The first innovation is enriching the Dalal-Triggs model using a star-structured part-based model defined by a “root” filter (analogous to the Dalal-Triggs filter) plus a set of parts filters and associated deformation models. The score of one of star models at a particular position and scale within an image is the score of the root filter at the given location plus the sum over parts of the maximum, over placements of that part, of the part filter score on its location minus a deformation cost easuring the deviation of the part from its ideal location relative to the root. Both root and part filter scores are defined by the dot product between a filter (a set of weights) and a subwindow of a feature pyramid computed from the input image. Another improvement is a representation of the class of models by a mixture of star models. The score of a mixture model at a particular position and scale is the maximum over components, of the score of that component model at the given location.
