Interpolation, interpolating - In computing mathematics, the method of finding intermediate values \u200b\u200bof the value according to the existing discrete set of known values.

Many of those who face scientific and engineering calculations often have to operate with sets of values \u200b\u200bobtained by experienced by way or by random sampling. As a rule, on the basis of these sets, it is necessary to construct a function on which other obtained values \u200b\u200bcould fall with high accuracy. This task is called approximation. Interpolation is called such a kind of approximation, in which the curve of the constructed function passes exactly through the available data points.

There are many of course difference methods of interpolation. Most
The Newton method is common to interpolation "Forward" (Newton - Gregory Method). Interpolation polynomial in this case has the form:

Today I want to show my Kucher, which I did at the past winter holidays. I will not describe the entire manufacturing process, since there are many articles on the Internet. I will write only about its main parameters.

Below are some photos made during the assembly of the device.

The coil is wrapped with a wire of 0.08 mm about 2000 turns on PVC pipe with a diameter of 50 mm and a height of 200 mm.

A plate from an old hard disk was used as a terminal. Everything else was collected according to the scheme which is located at the bottom of the page.

The first option was fed from the power unit of the old computer, the voltage of 12 V. Then a separate power supply was made, voltage of 30 V and with built-in cooling.

Sharing resources (CORS) is a W3C specification that allows you to carry out an interact link in the browser. Creating on top of the XMLHTTPRequest object, CORS allows developers to work with the same idioms as requests with one domain. Use option for CORS is simple. Imagine that Alice.com has some data that Bob.com wants to get. This type of query is traditionally not allowed in accordance with the same policy of origin of the browser. However, supporting Cors, Alice.com requests can add several special response headers that allow Bob.com to access data. As can be seen from this example, CORS support requires coordination between the server and the client. Fortunately, if you are a developer on the client side, you are protected from most of these details. The rest of this article shows how customers can perform requests with cross-start and as servers can configure themselves to support CORS. Continue ...
