Logo Creation Method - Repetitive Basic Shape Design (1)

Abstract: Repeating the design method of the basic form as one of the creative methods of the logo has been proved in many successful design examples and has a great design space. This article mainly introduces the concept, application characteristics and application form of the repeated basic form, and further deepens the understanding of the repeated basic form through design example analysis.

Keywords: logo design, basic form, repeating basic form

0 Preface

The sign is a kind of mass communication symbol. It expresses a certain meaning in a variety of concise images, conveys clear and specific information, and has strong functionality beyond words and words. An excellent logo should have original, clear and beautiful attributes, and its design means should also be diversified.
Repeating the basic shape design method as an effective means of logo design has been widely used in the actual design process. It repeats changes in a single basic form, creates a new and visually powerful art form, and provides a broader and richer design space for the logo.
1 Concept of basic form and repeating basic form

The basic form is the basic unit that constitutes the figure. A dot, a square, or a line segment can be used as a basic shape (Figures 1, 2, 3). The basic form is the most basic and fundamental form of the polymorphic design element. In the logo design, in addition to using this form, it cannot be limited to this simple basic element. In a basic unit (such as a 5 × 5cm grid), we can use points, lines, and faces to divide, overlap, and cut out forms to form a basic form of change. The form of this change is more full than a single basic form, and it is easy to form a visually stimulating image.

After the basic form is combined according to certain rules, a new figure is formed. This is the repeated basic form. Repeating the basic form In the process of composition, according to the needs of the image, the direction of change, or the adjustment of the area, thus forming a rhythmic beauty. There is both change and a strong sense of order. Taking Figure 2 as the basic form, the repeated basic forms obtained by arranging and combining in different directions produce a new graphic that is lively and orderly.

The shadow of repeated basic forms can be seen everywhere in our lives. The paving slabs on the sidewalks are repeated in thousands of basic shapes. Sometimes tiles change in direction, sometimes changing in area and color combinations to form a uniform and changing pattern, adding fun to passers-by. The five-ring logo of the Olympic Games (Figure 5) is well known to everyone, and these five rings are also the results of deductive basic shapes. The logo is based on a ring as a basic form, and is repeated to the right and down, respectively, to form a figure with three rings above and two rings below, and then the five rings are interpenetrated according to design requirements to connect them to each Other. The formation of a unified visual image conveys the Olympic concept of the integration and mutual solidarity of the peoples of the five continents. This sign has left a deep impression on all countries in the world.

A New Leap in Artificial Intelligence: An Olfactory Computer Chip

iOj65Nl7LTbCxCfecxgPy2wJ1QGGHkM6HfJ9naRXxlC8x1503992070180.jpg" />

[Netease Smart News August 30 news] With the rapid development of artificial intelligence, scientists are working hard to make the machine more like our brain, able to learn and understand the surrounding environment. Recently, Nigerian neuroscientist Agabi may have found a way to solve the dilemma of life: how to make air travel more enjoyable.

The graceful journey is exciting, but the long and crowded queuing security process often disturbs the elegance of the holiday. If you do not have to wait in line for security, how can you rely on a special device capable of sniffing explosives to work quietly in the background? ?

According to foreign media reports, neuroscientist Agabi invented the world’s first special neurotechnical device that can quietly sniff out explosives. The device was developed by his Silicon Valley startup company Konika and it was on TED in Tanzania last Sunday. Published at the global conference.

The field of artificial intelligence is frantically developing machines that can imitate the brain, or just like what Dr. Musk calls brain-machine interface research. Agabi discovered a way to fuse laboratory-grown neurons with electronic circuits. The 38-year-old said that while many people are trying to solve the limited processing capacity of silicon, he has turned his attention to "the world's most powerful processor ever." He said that to simulate the energy of 204 brain neurons requires a supercomputer. "Instead of copying a neuron, why not just use this biological cell as its own?" The idea is radical, but the results are incredible, he said.

Therefore, he worked with a group of geneticists, physicists, bioengineers, molecular biologists, and researchers to solve this problem and focus on solving problems that are particularly difficult for silicon devices. This includes the detection of volatile chemicals and explosives and even the prevention of diseases such as cancer.

Agabi said that Konigoule’s equipment is “the world’s No. 1” and can be the first in the world, mainly through breathing and sniffing the air. He said major brands, including tourism, have signed up. It is reported that the start-up's current income is 8 million US dollars (7 million euros) and is expected to jump to 30 million US dollars in 2018. One of the main challenges is to find a way to keep the neurons active. This is the secret that Agabi does not want to make public.

With the rapid advancements in artificial intelligence technology, scientists are working hard to make machines more like our brains and able to learn and understand the surrounding environment: this is a terrible prospect for many people.

Musk has repeatedly warned that artificial intelligence will eliminate the danger of human beings. He is developing a new project to implant "neural network" brain-computer interface technology. However, Agabi believes that the future of artificial intelligence lies in making machines more dynamic. He believes that his company can establish a human-like cognitive system based on synthetic living neurons in the next 5 to 7 years. "This is not science fiction," he told foreign media. "We want to build a brain with biological neurons — an autonomous system with intelligence. We don't want to build a real human brain."

Agabi spoke at the opening ceremony of the four-day TED Global Conference. It is reported that the annual TED Global Conference is held in Africa. This is the first time in ten years that the event has been held in Africa. (From: livemint Translation: NetEase Smart Compiled Robots?

5. Use of high-pressure nuclear phase meter

5.2 Host Inspection 5.2.1 System Self-Test: Connect two collectors to the self-inspection copper head, connect the calibration plug wire to the 220V power supply, and connect the Other end to the X and Y collectors, respectively. Hold two self-inspection copper heads, the host can display the same phase, the phase difference display should be 0-0.5 °.

Note: The phase angle displayed on the screen is based on collector X and the angle of collector Y to collector X.

If the phase difference is not displayed, the collector is not connected to the phase line, and the two plugs of the plug can be switched.

5.2.2 On-site calibration: At the nuclear phase of the site, the two collectors are first self-calibrated on the same phase of the measured circuit.

5.3 On-site use 5.3.1: Qualitative in-phase or out-of-phase phase, based on the results displayed on the LCD screen of the host computer;

5.3.2 LCD display X and Y indicate the signals of X and Y collectors respectively 5.3.3 LCD display When the low voltage prompt appears below X and Y, it indicates that the power supply of the X and Y collectors is too low, and 12V should be replaced in time. battery;

5.3.4 There is a low power indicator on the top of XY indicating that the power of the host is insufficient and the battery of the host should be replaced.

5.3.5 The “Wireless High-Voltage Kernelizer” appears at the top right of the display to show that the host is turned on.

5.4 The system can still work for a period of time when the XY collector or the host battery voltage is low. If the battery is unstable, the battery must be replaced. The battery should be replaced at the same time when the collector is replaced.

5.5 If the display of the host computer is abnormal, turning it off and then on again will return to normal.

5.6 Press the backlight key to turn on the display backlight.

5.7 Checking the Collector 5.7.1 When replacing the battery, turn the tail of the collector counterclockwise to remove the shell of the collector, and then open the battery cover to replace the new battery. Pay attention to the polarity of the battery and do not install the battery.

5.7.2 There are two kinds of contacts of the collector that can be replaced as needed. When the contacts are replaced, they can be removed by turning them counterclockwise.

5.7 On-site nuclear phase description 5.7.1 The X and Y collectors are respectively connected to the same high-voltage line. The host display should show that X and Y are in phase with a phase difference of 0---1°.

5.7.2 The X and Y collectors shall be arranged in the following phases for the nuclear phase at the phase of the high voltage line:

5.7.3 If you want to get accurate values, you should place one of the collectors on the collection point of the high voltage line, and move the other collector around the other collection point of the high voltage line before and after, or shift X and Y to find The most accurate phase angle.

5.7.4 In the nuclear phase, test data such as AA', AB', BB', BC', and CC all show different phases. This is because the measured two sets of power supply line wiring groups are different and may appear at 30°. Or 60° phase difference.

5.7.5 When the measurement is ≥10kV, the XY collector can be directly on the wire or insulation skin at the same time to perform 5.7.6 ≥66kV nuclear phase. The XY collector can adopt contact or non-contact method nuclear phase. When measuring 110kV or 220kV, add XY

The collector is placed 300mm to 1000mm below the high voltage line. When measuring 500kV, place the XY collector 1000-2000mm below the high voltage line and measure the allowable deviation of 300mm left and right.

5.7.7 Measure phase sequence: Suppose a line is phase A, place X on phase A, and Y on another phase. If 120° is displayed, it means that the phase sequence is the phase B; Showing 240° is the reverse phase sequence, which is the C phase.

5.7.8 Electrotechnical inspection: One of the collectors is hung on the high voltage line. If the corresponding symbol of the collector is displayed on the host screen, the high voltage line is powered. If the collector symbol is not displayed, the high-voltage line is without electricity (but the collector cannot replace the electroscope).

6. Maintenance

6.1 High-pressure nuclear phase meter is a precision instrument. Please do not open it at will.

6.2 Replace the battery at least once a year. 6.3 The product should not be stored in a humid, hot, dusty environment. 6.4 Insulation rods should be used for pressure test before the first use. 6.5 Insulation rods should be subjected to a pressure test once a year Note: The upper section of the insulation rod has a Built-in antenna 350mm long, can not withstand voltage test, built-in antenna and pole wall must

Video Surveillance System Common Faults and Solutions to Failure Experiences

It is of great significance to improve the quality of the monitoring system and ensure the stable operation of the system by taking appropriate measures to solve problems in response to different fault conditions. Here are some of the personal engineering experience to talk about the common fault points of the video surveillance system and the experience of troubleshooting.

1. Because the connection between the monitoring system equipment involves many lines, if the processing is not good, especially if the line connected to the main equipment is improperly connected or connected incorrectly, there will be disconnection, short circuit, poor insulation between the lines, miswiring, etc. Causes the performance of the device to be degraded or even damaged. In this case, cool analysis and troubleshooting should be performed according to the fault phenomenon to determine what kind of fault phenomenon may occur when there is a problem with the line connection. In addition, it should be noted that the connections between the various system devices and the various lines should meet the requirements for long-term operation of the monitoring system.

2. The mismatch of the characteristic impedance of the transmission cable may cause some vertical bars with equal spacing on the monitor screen, and the frequency of the interference signal is basically an integral multiple of the line frequency. This interference phenomenon is caused by the fact that the characteristic impedance and distribution parameters of the video cable do not meet the requirements. For such interference, the impedance of each device in the system should be matched as much as possible. Especially when the video cable is purchased, the cable quality must be ensured. If necessary, the cable should be sampled and tested.

3, the communication interface or communication protocol and other parameters are not set well, this situation often occurs between the control host and decoder or control keyboard and other devices with communication control relationship. In other words, the selected control host and decoder or control keyboard, etc., are not set during the installation of the communication protocol and other parameters, so the host, decoder, control keyboard, etc. should pay attention to the communication protocol and other parameters during installation Settings.

4. Common faults of video interference.

◆ A black bar or white bar appears on the monitor screen and scrolls up or down, which is the so-called 50 Hz power frequency interference. This type of interference is caused by the potential difference loop between the front end and the control center, which causes potential difference loops to enter the system. It is also possible that the power supply performance of the device itself is reduced.

◆ The image has snow noise. This type of interference is mainly caused by signal attenuation on the transmission line and coupling of high-frequency interference.

◆ The video image has ghosting, or the image is whitish, the character is jittery, or there are several vertical stripes with the same spacing on the screen of the monitor. This is because the characteristic impedance between the video transmission line or the device is not 75Ω, resulting in impedance mismatch.

◆ Twill interference, beating interference, power interference. When this interference is slight, it does not overwhelm the normal image, but when it is severe, the image is distorted and cannot be viewed. The reason for this is more and more complicated. For example, the quality of the video transmission line is not good, especially the shielding performance is poor, or the power supply of the power supply system has clutter, and there may be a strong interference source near the system.

Large area moire interference, also known as single-frequency interference. This phenomenon is mainly caused by the short circuit caused by the short-circuit of the video cable's core wire and the shield, or the failure caused by the open circuit, or due to the bad contact of the BNC connector.

5, equipment failure caused by power problems, there are the following possibilities:

◆ The power supply line or supply voltage is incorrect;

◆ The power is not enough (or the line of a certain power supply line is enough, the pressure is too large, etc.);

◆ Short circuit, open circuit, instantaneous overvoltage, etc. in the transmission line of the power supply system.

Monitoring system supporting equipment problem

It should be noted that the device may be damaged due to a power supply error or an instantaneous overvoltage. Therefore, before the supply of electricity, it must be carefully and strictly checked and checked. It must not be taken lightly.

6, due to the video cable's core and shielding network short circuit, open circuit caused by the failure. This kind of failure manifests itself in a deep and chaotic large-area moire on the monitor, so that the image is completely destroyed and images and synchronization signals cannot be formed. This happens mostly on BNC connectors or other types of video connectors. That is, when such a fault occurs, it is not always a problem in the entire signal line, but merely in the number of unfavorable connections. As long as these joints are carefully checked one by one, it can be solved.

7. Space radiation interference introduced by the transmission line. The reason for this interference phenomenon is that there are strong and high-frequency space radiation sources near the transmission system, the system front-end, or the central control room. The first solution to this situation is to build a system, to achieve a comprehensive understanding of the surrounding environment, and then try to avoid or stay away from radiation sources; Second, when the radiation source can not be avoided, the front-end and center equipment to strengthen the shielding, The pipeline of the transmission line adopts steel pipe and is well grounded.

8. The failure of the PTZ ◆ The common troubles of the PTZ are often not working or not rotating at all in the near future. In addition to product quality reasons, this situation is generally caused by the following reasons:

◆ PTZs that only allow the camera to be mounted are lifted when used. The hoisting method leads to an increase in the operating load of the pan/tilt. Therefore, the use of the hoisting method will soon cause damage to the drive mechanism of the pan/tilt, or even burn the motor.

◆ The total weight of the camera and its protective cover exceeds the weight of the PTZ. Especially for PTZs that are used outdoors, the weight of the protective cover is often too large, and there is often the problem that the PTZ will not move (especially the vertical direction).

◆ The outdoor pan/tilt head is faulty or even damaged due to poor ambient temperature, too low or waterproof, antifreeze and other poor performance.

◆ When the distance is too far, the camera (including the lens) and the pan/tilt cannot be controlled by the decoder through the operation keyboard. This is mainly because when the distance is too far, the attenuation of the control signal is too great and the control signal received by the decoder is too weak. At this time, a relay box should be installed at a certain distance to amplify the control signal.

9, the matrix host does not clean the image switch. This kind of failure is generally manifested in the screen after the cut, such as superimposed with other screen disturbances, or other lines of image synchronization signal interference. This is caused by the poor quality of the matrix switch and the lack of isolation between the images. If a radio frequency transmission system is used, it may also be caused by the system's cross-talk modulation and excessive modulation.

10, the monitor image contrast is too small, the image is light. If this phenomenon is not the problem of controlling the host computer and the monitor itself, it means that the transmission distance is too far and the video transmission line is attenuated too much. In this case, the line amplification and compensation device should be added.

11, the image clarity is not high, the details of the missing part, serious color signal may be missing or color saturation is too small and other phenomena, which is the high-frequency end of the image signal loss is too large, that is more than 3MHz frequency signal caused by the loss. In this case, the high frequency signal attenuation is too great due to the long transmission distance, and there is no amplification compensation device in the middle; or the distribution capacitance of the video transmission cable is too large; or because the transmission line core and shield line appear in the transmission link. Focused distributed equivalent capacitance.

12, color distortion. This is a fault phenomenon that easily occurs in long-distance video baseband transmission. It is also mainly caused by the transmission line being too long, causing excessive attenuation in the high frequency band of the signal. In this case, a compensator should be added.

A large-scale television monitoring system that operates in conjunction with burglar alarms is a high-tech and complex system. Although various failure phenomena may occur, as long as good quality is applied to the selection of equipment and equipment, and construction is strictly conducted in accordance with standards and specifications, there are generally no major problems. Whenever there is a problem, as long as you are calm and analytical, you can solve the problem faster.

4, treatment of bacteria

Loofah roots, stems, leaves can be washed after smashed juice 2 servings each time, 3 times a day.

Encyclopedia: Bacterial dysentery is referred to as bacillary dysentery. It is a gut infectious disease caused by Shigella (disease bacillus). The main clinical manifestations are chills, fever, abdominal pain, diarrhea, tenesmus, and mucous pus and bloody stools. Poisonous bacillary dysentery starts rapidly, suddenly high fever, repeated convulsions, drowsiness, coma, rapid circulatory failure and respiratory failure, and mild or absent bowel symptoms, the condition is dangerous. Bacterial strains are distributed all year round and are common in summer and autumn. They are common and frequently-occurring diseases in China. The disease has an effective antibacterial treatment, a high cure rate. The poor efficacy or chronic increase is due to the lack of formal treatment, lack of timely treatment, improper use of drugs, or infection by resistant strains.

5. Insufficient milk treatment

Method 1: 60 grams of loofah, a trotter, stew cooked when the food to eat.

Method 2: 1 old loofah, dried in the shade, burned charcoal, powdered, and rice wine, 9 grams each time.
