brainwave frequencies

is possible to interpret the point multiplication as a set that assigns the direction and intensity of the direction vector to a point. synthesis of medium wave in 3D space In 3D space, the superposition principle still applies:(Above, left-hand coordinate system, Z=sin (y) +sin (x) +sin (x+y)) 3, applying composite waves to the complex system to test the above waveform The following is the effect of shader the pixel position and normal in the fragment shader with a variant of the sine function

Do you notice the noise pollution of the surrounding environment when you take the transportation every day? In the face of annoying noise in the ear, in addition to blocking the ear of this passive method, we can now take the initiative, using sound to eliminate the noise. The principle of active noise reduction is summed up in a sentence: phase cancellation is achieved by emitting sound waves and noise interferences with the same frequency and amplitude as the opposite of the noise phase. To

Compared to the traditional Wi-Fi signal, the unused frequency of white spaces will have a more significant development prospects, so Google created an API that can make this part of the resource easier to use. Using this Spectrum database API, the Spectrum data API can be used to search for frequencies not yet occupied by television and radio signals, especially in the U.S. region, and to register devices using these

Encountered a problem in the project, the use of push middleware, the results using MAVEN download is not down, then directly after the manual download, copy to the local repository,There was a problem when the results were released.Because the release is directly on the test server, the submitted SVN code is packaged and published.At that time had been struggling to modify the default central warehouse, add the middleware point to the warehouse, has not achieved the desired effect.Finally sudde

see an LO local loopback network card, where is eth0? Quickly check the network configuration, sudo vi/etc/network/interfaces, find the configuration is in, that is why eth0 did not? Using Ifconfig -A to see all the network card, found Eth0, but more out of the eth1. Brainwave, change it. interfaces file sudo vi/etc/network/interfaces replace eth0 with eth1 and restart Network Service sudo/etc/init.d/networking restart Haha, Nic good ~~3. And trag

injured, do not deduct the amount of purple blood (in fact, the portion has been deducted, but there is a buffer time), but the red or white part;7. If the poison is affected by the shield effect?When making ordinary blood strips, we usually use UISlider.But here is the effect of shielding and poisoning, obviously not enough with UISlider. My first thought is to use multiple blood strips superimposed together, to distinguish between normal blood bar, poison blood bar, shield blood bar. But how

myrect->height = height (); 6 0 0, Myrect,1, shapeset,yxbanded);The sixth parameter passed to the function is null when the mouse is set to pass throughView the definition of the function found that this parameter is of type xrectangle*The following direct conclusion, when set mouse penetration, if this parameter is NULL, then the entire window will be penetratedThen the seventh argument is that the control is set to Pierce and cancel through (Cancel to 1)However, you must set the zone when you

interest driven similar user experience is entertainment to death. Entertainment to death is to enhance the user experience the greatest enemy. Quora this kind of website will be more, but Quora is still biased to practicality. More sensitive and close to people's inner needs of the site will gradually rise. Big cat I personally have three superficial generalizations about the relationship between user value and user experience: The user value and the user experience are relative. BEIJING-Ea

local loop network card, where eth0 run? Quickly look at the network configuration, sudo vi/etc/network/interfaces, found that the configuration is in, that is why eth0 did not? Use Ifconfig-a to view all network cards, found Eth0, but more out of the eth1. Brainwave, change the interfaces file. sudo vi/etc/network/interfaces Replace eth0 with eth1 and restart network services sudo/etc/init.d/networking restart Haha, the network card is good ~

Recently used VSTO to do a small project, where one of the requirements is to save a number of formatted areas of an Excel worksheet in a separate Excel file, requiring that the source format be preserved. Although the requirements are simple, there are a few technical points to figure out: 1. With format copy, but only copy values and formats, do not copy formulas, references, checksums and so on. 2. Save As Excel The first question, I thought it was very simple, direct use paste, paste all

Syrup on the lens, is it true that someone wants to eat the cookie footage? In fact, this is a commercial photographer Justin Van Brainwave's creative performance, but the photographer did not use the real lens to pour syrup oh! So lifelike image, in fact, it is not difficult, as long as the finger can be shot. How did the photographer do it? Let's have a look. No need to break the camera, but also to make realistic and interesting business image creation, commercial photographer Justin van usi

OverviewEncounter a requirement: Use JS to generate a fixed-length string. On the internet to check a lot of information, online methods are more troublesome . I had a brilliant idea and realized a simpler approach. Record it for future development, and I believe it will be useful for others.JS Generate random stringJS generates random strings with a wonderful notation ://输出随机字符串const randStr = () => Math.random().toString(36).substr(2);The browser developer tool enters 5 times and outputs the f

Suddenly think of the previous contact Flash will picture binary system to pass to PHP, brainwave with $globals[' http_raw_post_data '] to get. So in depth check, originally PHP by default only recognized application/x-www.form-urlencoded standard data type, therefore, to type such as text/xml or soap or Application/octet-stream Such content cannot parse, if use $_post array to receive will fail! Therefore, the prototype is retained and given to $glob

you to press any key at this time to cancel the shutdown, that is, in this screen interface for a short number of seconds, if you suddenly do not intend to shut down now, you can also cancel it. In fact, I often encountered this thing, such as habitual shutdown before bedtime, but suddenly brainwave can not help but also want to see whether there are text messages or unread messages. Maybe there's another reason for you to spend a little bit more wit

guess, use it as a application/octet-stream. To learn the MIME types of various files, view them in the Win98 my Computer-> View-> Folder Options-> File type. So I brainwave, think in the ASP can first the word data in a byte-throttling way out, then mark its Conntenttype property as Application/msword, and then send it to the client, after the client received the resource, according to its MIME type, will automatically invoke word on the client (if,

Two days ago, I went to Mouchangqing's blog, found that he wrote an article is excellent webmaster tools recommended by the Baidu statistics heat, look at the brainwave, combined with the ZAR before see an article, indeed each site users like to click the location is not the same, if you use the Baidu statistical thermal attempt, Then you can know the user went to your site like what place, and then you targeted in the vicinity of the location of the
