计算机的视频功能是很多计算机用户最常用的功能之一,计算机的视频能力自然一直是用户关注的焦点,尤其是在宽带网络发达,DVD-ROM 和DVDRW 逐渐普及的今天,我们不仅仅追求“能够流畅播放”,更关注“回放的质量”。对于不影响速度的情况下的视频质量改进,这几年视频渲染器的的进步还是有目共睹的,下面的图就是著名的Media Player Classic(简称MPC)的视频渲染选项:
DS1991是一款加密存储器型信息纽扣,体积小巧,便于携带,具有防尘、防潮、抗震等特性。采用DS1991设计的公交卡能较好地解决IC公交卡存在的携带不便、易受损坏、不能应用于恶劣环境等不足,相对IC卡系统具有操作方便,稳定性高,便于携带,使用寿命长等特点。
This paper presents an overview of the magnitude determination of the November 14, 2001 west of Kunlun Mountain Pass (KMP) earthquake at the juncture of Xinjiang and Qinghai, northwestern China. Compa
依赖于PC的指纹识别系统,技术上虽然已经很成熟,但造价高、体积大、系统复杂。高性能DSP芯片运算速度快,非常适合计算量大的实时信号处理。用DSP实现指纹识别系统,有独特的优势。
A method for determining medium quality factor is developed on the basis of analyzing the attenuation dispersion of the arrived first period P wave. In order to enhance signal to noise ratio, improve
Strong ground motion of an earthquake is simulated by using both staggered grid finite difference method (FDM) and stochastic method, respectively. The acceleration time histories obtained from the bo
Under harmonic wave excitation, the dynamic response of a bilinear SDOF system can be expressed by the Hilbert spectrum. The Hilbert spectrum can be formulated by (1) the inter-wave combination mechan
1937年8月1日4时35分,山东菏泽县(曹州)发生7级地震,震中位置:北纬35.4度,东经115.1度。极震区东到马岭岗,西至东明县王坝岗,南到通古集,北至耿海,烈度达Ⅸ度。同日18时41分该地区又发生一次6(3/4)级地震,震中位置:北纬35.3度,东经115.2度。极震区在吴油房、朱楼、大马庄、王堂一带,烈度为Ⅷ度。此次地震使菏泽、东明二县遭受严重破坏,周围14县也受到不同程度破坏。极震区内
