1. It is estimated that it is not so obvious. There will be pop-up windows or small windows in the trading limit display. After all, the main interface is used to display the K-line chart. Look at your chart, you don't need so many technical indicators. The next two are OK. The first line is still the volume column chart, the second line is KDJ, and the third line is brin line. It's better to look at this, and it's not so messy. It's just a suggestion

5. The research of virtual reality originated from the 60th generation of computer graphics, computer interface technology, image processing and pattern recognition, transmission technology, voice processing and audio technology, high-performance computer system Instry, intelligence and other fields have made full use of half a century to develop the virtual reality instry and lay a solid foundation. Facebook has acquired oculus with us $2.04 billion, which is the leader of VR instry. It is expected to launch the second generation of commercial virtual reality wearable glasses oculus rift in the first half of 2010; Sony 3D helmets instry leader is expected to push Playstation VR and ps-4 to use in half a day. At present, nearly 20 games are on sale at the same time. VR, AR, mrcr say ghost VR (virtual reality) virtual reality immerses itself into the virtual world to consume content to give users experience. Some content, such as movies, competitions, scenery, news, etc., can interact with each other. For example, VR game tracking, VR game tracking, VR game tracking, VR game tracking, VR game tracking, VR game tracking, VR game tracking, VR game tracking, VR game tracking, VR game tracking, VR game tracking, VR game tracking, VR game tracking, VR game tracking There are three types of VR consumer devices, such as gait, eyeball, squat and so on: it needs to cooperate with the representative of computer wearable device, oculus rift, which is not yet commercially available; VR conversion bracket represents storm mirror and cardboard; For example, Nokia ozo VR is still in its infancy, lack of content application, comfort of wearing, and According to AR (augmented reality) augmented reality, VR gives consumers 100% of the virtual world. Ar real world entities help consumers explore the real world and deliver typical ar devices with the help of digital technology. Google glass (yingeye) stares at a restaurant to help search for relevant information and display. Staring at a beauty to show its circumference is similar to an application. I take photos with my mobile phone and then do it Image search or PS operation computing ar computing ar means real interaction with the physical world Image processing ability and Chinese network connection ability enhancement, AR application is more and more extensive, VraR difference: in short, virtual reality (VR) viewing scene full false consciousness into the virtual world augmented reality (AR) viewing scene real part false virtual information into the real world interaction difference VR equipment: VR pure virtual scene VR equipment is more used for user and virtual scene interaction, more use: position tracker Data glove (5DT), capture system Data helmets and other ar devices: because the combination of AR real scene and virtual scene basically requires camera shooting, the combination of camera shooting and virtual picture display is more than Google glass (in fact, strictly speaking, some procts with camera power on iPad mobile phones are used for AR, and ar software should be installed) technology difference is similar to game proction, creating virtual scene for experiencing the core graphics technology Application game theory: traditional game and entertainment equipment upgrade mainly focuses on whether the virtual scene is good or not, whether the experience is related to the real scene or not, VR equipment is often immersed in typical equipment, oculus rift ar application of computer vision technology, AR equipment emphasizes the visual function of restoration rather than self recognition and tracking of objects; Independent tracking and 3D modeling of the surrounding real scene. I call Maya to make a very similar typical ar device according to the scene. The upgraded Google Project Tango MR (mix reality) mixed reality of ordinary mobile phones. Strictly speaking, I visit the enhanced reality function hololens & gt; of hololens and AR devices experienced by Microsoft; Oculus rift designs motorcycles in the real world, can real components play games in the living room without wearing the living room, and integrate some virtual elements into the total MR equipment to give the chaotic world: Digital Simulation Technology (display, sound MR technology more imagines the physical world of space, real and thorough biting, and contains the function of VraR device. According to the news, Microsoft's hololens sender version sold for $3000 in the first six quarters of 2001. Would you like to jump the ticket? Cr (digital reality) image reality. Google's investment in magic leap puts forward the concept, which mainly emphasizes that it is the same as VraR technology, and it thinks that it is similar to Mr's actual concept Both blur the physical world and the virtual world to facilitate the completed tasks, application scenarios The content provided is similar to that of Mr procts. Its core is "the angle picture of magic leap designed by light wave concting prism is directly projected on the user's visual film to deceive the brain." it is different from the screen projection display technology. The technology can achieve more real impact and directly interact with the visual film to solve the problems such as holens' narrow field of vision or vertigo. At the end of the paper, Mr technology is the same as Google's magic leap description technology The particularity of magic leap echoes with Ma Huateng's "Chinese membrane projection" mentioned earlier

6. When playing, the operation will be blocked, which is not fully supported. So the one on the first floor is pure fart! The machine is an MP3 player, playing is the restoration of music, excessive pursuit of playing aqeflac and other lossless, then there is the meaning of existence?? Just call the wav player

7. The principle of AES encryption and decryption algorithm and AVR implementation

AES is the group key, the algorithm inputs 128 bits of data, and the key length is 128 bits. NR is used to represent the number of rounds of encryption for a data packet (the relationship between the number of encryption rounds and the length of the key is listed in Table 1). Each round requires the participation of an expanded key (I) with the same length as the input packet. Because the length of the external key K is limited, a keyexpansion program is used to expand the external key K into a longer bit string to generate the encryption and decryption keys of each round< Each loop transformation of AES consists of the following three layers:
nonlinear layer: SubByte transformation
line and row mixed layer: perform shiftrow and MixColumn operations
key adding layer - addroundkey operation

① SubByte transformation is a kind of nonlinear byte transformation acting on each byte in the state, which can be mapped by the calculated S-box< br />Schange:
ldi zh,＄01; Point the pointer to the first address of S-box
mov ZL, R2; Take the data to be searched as the pointer low address
ldtemp, Z +; Take out the corresponding data
mov R2, temp; The data exchange is completed by looking up the table
.
.
.
RET

② shiftrow is a byte transposition. It circulates the rows in the state according to different offsets, which are also selected according to NB [3]< br />shiftrow:; This is a subroutine of byte transposition
mov temp, R3; Because it's 4 × 4
mov r3,r7; r2 r6 r10 r14 r2 r6 r10 r14
mov r7,r11; r3 r7 r11 r15---r7 r11 r15 r3
mov r11,r15; r4 r8 r12 r17 r12 r17 r4 r8
mov r15,temp; R5 R9 R13 R18 R18 R5 R9 R13
mov temp, R4
mov temp1, R8
mov R4, R12
mov R8, R17
mov R12, temp
mov R17, temp1
mov temp, R18
mov R18, R13
mov R13, R9
mov R9, R5
mov R5, temp
RET

in MixColumn transformation, Each column in the state is regarded as the result of multiplication of polynomial a (x) and fixed polynomial C (x) on GF (28). The coefficient of B (x) = C (x) * a (x) is calculated as follows: * operation is not ordinary multiplication operation, but special operation, that is,
b (x) = C (x) · a (x) (MOD X4 + 1)
for this operation,
B0 = 02. a0+03 A1 + A2 + a3
let xtime (A0) = 02. A0
Where is the symbol "." It represents the congruence multiplication of an eight degree irrecible polynomial< br />mov temp,a0; This is a mixcolimn subroutine
rcall xtime; Call xtime program
mov A0, temp
mov temp, A1
rcall xtime
EOR A0, A1
EOR A0, temp
EOR A0, A2
EOR A0, A3; Complete the calculation of B (x)
.
.
.
.
xtime:; This is a subroutine
LDI temp1, $1B
LSL temp
BRCs NEXT1; If the highest bit is 1, then transfer
next: ret; Otherwise, nothing changes
NEXT1: EOR temp, temp1
rjmp next

for the inverse change, the matrix C should be changed to the corresponding D, that is, B (x) = D (x) * a (x)

4. Addround is a bit XOR of the corresponding byte in the state of the circle key

⑤ according to the property of linear change [1], decryption operation is the inverse change of encryption change. It will not be described in detail here

1.2 round change

for different grouping lengths, the corresponding round change times are different, as listed in Table 1< Key extension

1.3 key extension
AES algorithm uses the external input key K (the number of words in the key string is NK), and obtains a total of 4 (NR + 1) words of extended key through the key extension program. It involves the following three moles:

① position transformation: changing a 4-byte sequence [a, B, C, D] into [b, C, D, a]

② S-box transformation (subword) -- to replace a 4-byte S-box

③ transform rcon [i] - rcon [i] represents 32-bit word [xi-1,00,00]. Here x is (02), such as
rcon [1] = [01000000]; Rcon[2]=[02000000] Rcon [3] = [04000000]...

generation of extended key: the first NK word of the extended key is the external key K; The following word w [[i]] is equal to the "XOR" of the previous word w [[I-1]] and the previous nkth word w [[i-nk]], that is, w [[i]] = w [[I-1]]

the money saved by my next WinXP will be enough to buy a big hard disk
you'd better make an exception to take Yuri's revenge. You've got both games!

(hope to be helpful to the friends who come to this problem later)

(from right to left) the 1 in the 9th place is ignored

In fact,

is equivalent to dividing by the remainder of irrecible polynomial m (x) = x ^ 8 + x ^ 6 + x ^ 5 + X + 1.

10. South Chen and North Li (South Chen and North Li) south Chen and North Li
in history, South Chen and North Li
1. There is a saying in the history of the Communist Party of China that "South Chen and North Li meet to build the party"“ Chen refers to Chen Duxiu and Li refers to Li Dazhao. At the beginning of the founding of the Communist Party of China, the Central Party branch established by Chen Duxiu was in Shanghai, which was relatively independent from the Beijing Branch established by Li Dazhao. The saying "South Chen and North Li" shows that the party organization with close identity has not yet been born [1]. 2. Chen Guoda, who calls himself "the son of the earth", and Li Siguang, the "father of Geology", are called "South Chen and North Li". Academician and geologist of the Chinese Academy of Sciences. 3. In the south of China, the surname Chen is the most important, and in the north, the surname Li is the most important, so it is also called "South Chen and North Li".
