    There are _NO_ standard sample rate for the samples used in modules. But most often the samples are done on the rate called C-3 (which is about 16574 Hz IF you have a PAL machine). Sometimes drums are sampled at A-3 (around 28 kHz), and some sounds are at ~8 kHz or anything else to save space.

  • The LM35 of National Semiconductors that is used in this project is a precision centigrade temperatu

    The LM35 of National Semiconductors that is used in this project is a precision centigrade temperature sensor, which has an analog output voltage. It has a range of -55潞C to +150潞C and a accuracy of 卤0.5潞C . The output voltage is 10mV/潞C . The output voltage is converted by the AD convertor of the AT Mega8. The temperature is displayed on an LCD module. In this example the thermometer has a range of 0潞C to 40潞C and a resolution of 0.5潞C. IF you want to have a readout in Fahrenheit you can use the LM34.

  • pHash is an implementation of various perceptual hashing algorithms. A perceptual hash is a fingerpr

    pHash is an implementation of various perceptual hashing algorithms. A perceptual hash is a fingerprint of an audio, video, or image file that is mathematically based on the audio or visual content contained within. Unlike cryptographic hash functions that rely on the avalanche effect of small changes in input leading to drastic changes in the output, perceptual hashes are "close" to one another IF the inputs are visually or auditorily similar. As a result, perceptual hashes must also be robust enough to take into account transformations that could have been performed on the input.

  • A Convex Hull is the smallest convex polygon that contains every point of the set S. A polygon P is

    A Convex Hull is the smallest convex polygon that contains every point of the set S. A polygon P is convex IF and only IF, for any two points A and B inside the polygon, the line segment AB is inside P. One way to visualize a convex hull is to put a "rubber band" around all the points, and let it wrap as tight as it can. The resultant polygon is a convex hull.

  • I ll probably write up a short article next week outlining how the ActionScript works, so people can

    I ll probably write up a short article next week outlining how the ActionScript works, so people can modIFy it, and work with it more easily in Flex. You can download the component and source code here. There are some instructions in the FLA on how to use it. Note that this is not a compiled component, so it won t show up in the components panel. You will have to copy the component, and the source file into your project. IF anyone really wants a compiled version, let me know and I can provide one. As always, I d love to hear how people use it, and would appreciate it IF you would post back to the comments IF you make any signIFicant modIFications so that other people can benefit from them.

  • 本体推理是语义网研究的一个热点问题

    本体推理是语义网研究的一个热点问题,目前大多数查询系统都是专家系统,但在 专家系统中,知识的表现形式都存在各种不足,本文在借鉴原有专家系统优点的基础之上, 介绍了一个基于SWRL 推理机制的框架,它弥补了专家系统中的不足之处,解决了以往的 本体不能表示“IF...then...”这样句式规则的缺点,另外利用本体技术使我们的系统在其它类似 的系统中可以重复使用。

  • OTSU Gray-level image segmentation using Otsu s method. Iseg = OTSU(I,n) computes a segmented i

    OTSU Gray-level image segmentation using Otsu s method. Iseg = OTSU(I,n) computes a segmented image (Iseg) containing n classes by means of Otsu s n-thresholding method (Otsu N, A Threshold Selection Method from Gray-Level Histograms, IEEE Trans. Syst. Man Cybern. 9:62-66 1979). Thresholds are computed to maximize a separability criterion of the resultant classes in gray levels. OTSU(I) is equivalent to OTSU(I,2). By default, n=2 and the corresponding Iseg is therefore a binary image. The pixel values for Iseg are [0 1] IF n=2, [0 0.5 1] IF n=3, [0 0.333 0.666 1] IF n=4, ... [Iseg,sep] = OTSU(I,n) returns the value (sep) of the separability criterion within the range [0 1]. Zero is obtained only with images having less than n gray level, whereas one (optimal value) is obtained only with n-valued images.
