When making web chat tools, how do you usually use real-time message delivery? All I know: Ajax polling (all say wasted resources, bad ...) ） EventSource (support is not good, IE is not supported at all.) ） Websoket (not very well known ...) ） Moreover, Baidu after the search learned that in the browser does not support WebSocket case, incredibly there is a third-party library to achieve WebSocket, whether the so-called WebSocket is like EventSource, the core principle is to use

Title Address: http://poj.org/problem?id=1422there are n small towns on a map, and there are forward edges connecting two of them, and these edges cannot form loops. Now choose some small town airborne soldiers (1 small towns up to 1 soldiers), soldiers can go down to the end, ask the least airborne several soldiers, can walk through all the town. The minimum path coverage problem. First, divide each point

great deal ."The story allows us to come up with the following experiences: After-Event Control is not as good as in-case control, while in-case control is not as good as in-case control. Unfortunately, most business operators fail to understand this point, it will not be compensated until the wrong decision has caused significant losses. It is often the result of a well-known "Airborne Troops. When I heard this story, it showed the skills of consul

Pesticide Residues on fruits and vegetables have always been a problem for consumers. Traditional methods to remove pesticide residues are nothing more than water, rice washing water, and water cleaning. Later, there were some fruit and vegetable cleaning agents similar to detergent on the market, one or two drops of water can also be used to remove pesticides during dish washing. Using ultrasound to clean fruits and vegetables is another method. In s

Performance requirements of PACS image workstation in image Department 1. The image workstation must be individually optimized for each image mode. The displayed image must have diagnostic significance and quality (diagnostic quality ). A. CT and MR should be able to automatically draw the positioning line of the Plane Surface B. synchronous display of related CT/MR Series C. DSA supports dynamic display and dicom jpeg lossless compression. D. The echo map supports dynamic display and dicom jpeg

elaborate on it here, because gender recognition only includes two types of training sample tags: male and female. It should be noted that eigenface is based on PCA and is an unsupervised model that is not suitable for gender recognition tasks. The demo here uses fisherface. For video face recognition, you simply add a videocapture and a cascadeclassifier for face detection. You can use the SAVE and load functions to save and call the trained model. This is easy to understand. Finally, let's ta

this part of the tweeting is indeed lacking, we can use bbe's high-pitched excitation to achieve this. The harmonic wave will not damage the overall auditory perception. 10. 20 kHzThis is ultrasound, which is invisible to human ears. You don't need to tune it unless you have a special function. Among the above frequency points, the most important and key frequency points, in the 10-frequency band, 80, 200, 250, 400, 800, 1.2 K, 2.5 k, 4 K, 6.4 K,

What is Dicom? DICOM is the abbreviation for digital Imaging and communication of Medicine, the American Academy of Radiology (American College of RADIOLOGY,ACR) and the American Association of Electrical Manufacturers (national Electrical manufacturers Association,nema) organization developed a standard name specifically for the storage and transmission of medical images. After more than more than 10 years of development, the standard has been widely accepted by medical device manufacturers and

SOA can be used as a metaphor for bats, bats to use their own ultrasound to capture food, but also need ultrasound to avoid obstacles, the same enterprise, both want to use software to profit, but also hope that the software to circumvent the risk of the enterprise.

method uses close-range, aerial and remote sensing images to establish a realistic surface model including top details. This method is relatively time-consuming and expensive, and the automation degree is not high. 3) the node group method, 3D reconstruction data sources of geometric surface models can be established using a large amount of 3D point group data quickly obtained by Laser Scanning and Ground Movement Measurement. Data Obtained remotely can also be divided into satellite images, ae
