The definition of divisible: A, B is two arbitrary integers, b!=0, if there is an integer q, so that A=b*q, said "A can be divisible by B", or "B can be divisible by a", or "B is a factor", or "A is a multiple of B", with the notation "B|a".The nature of the divisible:(1) b|0, because 0=b*0(2) 1|a, because a=1*a(3) B|a (4) a|b, b|c = A|c, because a|b,b|c = B=A*Q1,C=B*Q2 = c=a*q1*q2The theorem 1:a is the sam
the fixed-point decimal in the QN format is divided by 2^n. In a computer or an integer, we think of it as the actual expressed value.In turn, an actual value to be expressed by X is converted to the QN type of the fixed-point decimal time, is x*2^n. For example, 0.2 of the Q12 type fixed-point decimal is: 0.2*2^12 = 819.2, because this number to be stored in integers, so is 819 is 0x0333. Because the decimal part is discarded, 0x0333 is not an exact 0.2, in fact it is 819/2^12 = 0.199951171875
the circuit infigure 1delivers programming voltages to a EEPROM under the control of an External DAC (not shown). You can replace the DAC with a potentiometer to create a general-purpose power supply operating from 12V and able to deliv ER a variable output voltage of 0 to 32V. Asfigure 1shows, a Linear technology LT1072HV variable-boost switching regulator, IC1, drives a Class a amplifier comprising operational amplifier ic2, Voltage-boost-stage q3, and Emitter-follower Darlington transistor q2

endpoint, you can determine the turn of a broken segment by calculating the symbol (P2-P0) x (p1-p0):if (p2-p0) x (P1-P0) > 0, then p0p1 to the right after P1 point to get p1p2.if (p2-p0) x (P1-P0) if (p2-p0) x (p1-p0) = 0, then the P0, P1, p2 three points collinear.
Determine if two segments intersect:We determine whether two segments intersect in two steps:(1) Rapid rejection testThe rectangle with the diagonal line p1p2 is R, the rectangle with the segment q1q2 diagonal is T, and if R and

I. Practice REQUIREMENTS: Write a simple text processing tool with three tasks, one to receive user input, one to format user input, and one to file formatted resultstwo. Analysis:Three tasks, that is, three threads. The input, conversion, and writing of these 3 threads. So what are the inputs that are written, and how are the other threads taken out? We can use the queue queues to write the characters entered by the user into the queue before converting. After the conversion is complete, And t
Although Gnu/linux is not omnipotent, it does offer free, open solutions in many cases. These two days I want to do a simplified, search the online score typesetting software, found the Lilypond software based on the GPL protocol. But Lilypond is used to make staff. Fortunately, a jianpu-ly.py script written by Silas of Cambridge University was found to be able to eventually generate simplified by calling Lilypond. See here for a detailed description of it.The script supports the following simpl

A typical DC motor control circuit is shown in the figure above. The circuit is named after the "H-Bridge drive circuit" because its shape resembles the letter H. 4 transistors make up the 4 vertical legs of h, and the motor is the horizontal bar in H (Note: The figure is a schematic, not a complete circuit diagram, where the transistor's drive circuit is not drawn).
The H-bridge motor drive circuit consists of 4 transistors and one
good Python program feels like reading English. It allows you to focus on solving problems rather than figuring out the language itself. JavaScript is one of the most useful languages JavaScript is not as simple as python, but it can run on every platform: Mac, Windows, iOS, Android, and more. Every single web browser, even a new device like smartwatch, uses JavaScript on some features. after JavaScript, try Ruby and Ruby on Rails Ruby on Rails is a
Yesterday, Microsoft released. Net micro framework SDK 2.5. Many may not know the micro framework very well. This version is called micro because it will run on a smaller mobile device and can run on a version without MMU of ARM7. The first version was released on July 13. Netmf is smaller than Windows CE and can run completely out of the operating system environment. This is very suitable for embedded systems .. Net micro framework has been applied to Microsoft's

These three products show Apple's strengths. Apple will not keep pace with existing products, but fix existing product defects and launch better products. The current smart watch industry is like this. Many companies are eager to launch products and hope to gain a place in the smart watch market.
This chaos means Apple will have the opportunity to subvert the smart watch market and seize the market with a
