According to the fact that the basic features of apalmprint, including principal lines, wrinkles and ridges, havedifferent resolutions, in this paper we analyze palmprints using amulti - resolution method and define a novel palmprint feature, whichcalled wavelet energy feature, based on the wavelet transform. wef can reflect the wavelet energy distribution of the principal lines, wrinkles and ridges in different directions at different resolutions scales, thus it can efficiently characterize palmprints. this paperalso analyses the discriminabilities of each level wef and, according to these discriminabilities, chooses a suitable weight for each levelto compute the weighted city block distance for recognition. theexperimental results show that the order of the discriminabilities ofeach level wef, from strong to weak, is the 4th, 3rd, 5th, 2nd and 1stlevel
作為對現有人體生物特徵識別技術的重要補充,掌紋識別有著其獨特的優點:掌紋比指紋含有更多的可區分信息掌紋採集設備的價格比虹膜採集設備的價格要低廉得多掌紋特徵比簽名特徵更為穩定掌紋識別可獲得比人臉識別更高的識別精度掌紋含有獨特的線特徵包括主線和皺褶,這些線特徵具有很強的區分能力,並可以在低解析度圖像中提取出來可以將手掌上的各種特徵融合在一起建立一個高精度的生物識別系統等。Seismic survey is a new method used to civil engineering area in recent years. it was widely applied to survey or detecting of roadbase, dam base, foundation of building, tunnel, river bed, lake bed and etc. the chief methods are reflection method, refraction method, wave velocity testing, surface ware survey and transverse wave suivey. seismic survey can divide different layer, measure the incidence of sediment stratum, detect the structure of rock, test the handle effect of surface wave survey, we can calculate the carrying capacity of foundation and other mechanical parameters. this technique can give service to some big engineering departments such as highway developing company, survey design company, water supply company, plan bureau, construct bureau etc
應用於工程的主要方法有反射波法折射波法波速測井面波法及橫波勘探等。地震勘探能詳細劃分地層高精度地確定沉積地層的傾角能夠準確探明巖體構造褶皺斷層破碎帶裂隙帶對于回填工程路基壩基,地震勘探可以檢測其回填處理效果對于隧道工程,可以探測隧道洞體的圍巖分類及洞口地質情況利用面波勘探所得到的瑞利波速度,可以準確推算地基的承載力動彈模量等力學參數。As the automobile industry ’ s growing, more and more aluminum alloys have used in the manufacturing of automobile and aluminum alloys replaced parts of steel planks used in automobile parts which is one of the key resources for light weighting of automobiles. but as aluminum alloys have some limitation in forming such as crinkle, fracture and difficult for welding, the industrial scale of aluminum alloys is limited
隨著汽車產業的發展,鋁材在汽車上的用量迅速增加,鋁合金取代部分鋼材成形汽車零件已經成為解決汽車輕量化的關鍵手段之一,然而由於鋁合金在傳統的沖壓成形中會出現難以消除的裂痕和褶皺,以及深沖性能比較差、焊接難度高等特點,使得鋁合金的大規模運用受到限制。Viscose staple fiber with high moisture is a kind of cellulosic fiber with relatively higher dry - strengh and wet - strength , and wet modulus, whose material is high quality cotton and wood pulp being 100 natural regenerated fiber, it has a soft and lubricious feeling, and a strong feeling of silk touching it will give you a very comfortable feeling
高濕模量粘膠短纖維是一種具有較高的干強、濕強度、濕模量的纖維素纖維,它是以優質棉木漿為原料的100的天然再生纖維,纖維質地柔軟滑爽,絲質感強,具有良好的手感和懸垂感,織物形態穩定性強,耐洗滌,抗褶皺,穿著舒適。The warm - up device can reduce the temperature difference between the cloth and the molten film, so it improve the intensity of antis tripping, reduce the gaffer of the film
預熱裝置縮小了材料和熔融薄膜的溫度差,保證了塗覆后抗剝離強度高,減輕塗覆后的皺褶。The a - c films were quantitatively analyzed by boxing dimension method. it indicates that with the fractal dimension increase, such surface of a - c film has more complicated microstructure, more and finer nanostructured grooves, so that it is able
隨著分形維數的增大,薄膜的表面具有更加復雜的結構,表面有更多和更精細的具有納米尺度的凹凸、皺褶和缺陷結構,具有更大的吸附和容納氣體的能力,從而提高水滴薄膜表面的接觸角。分享友人
