Three-dimensional visualization technology of power transmission lines, intelligent management of power supply chain

Content: Power transmission line is an important part of power system, and the management and maintenance of the line is the key to keep the power supply chain smooth. How to manage power transmission lines efficiently and predict the potential problems of lines in advance is the core issue of intelligent and digital transformation in the field of power supply. Three-dimensional visualization technology can visually display power transmission lines, and realize real-time monitoring and operation and maintenance management of lines based on data model, which is convenient for power managers to finely manage line status. # Three-dimensional visualization of power transmission lines #

Three-dimensional visualization technology can establish three-dimensional cultural design based on power transmission lines and realize comprehensive monitoring and management of lines. Through three-dimensional digital modeling, the lines can be visually displayed and the information can be visually expressed. In addition, with the help of artificial intelligence, big data and other technologies, all data in the power supply chain can be intelligently analyzed and processed. Power managers can analyze these data, predict the operation status of the line and maintain it in time.

The intelligent analysis and management function of three-dimensional visualization technology can not only help power line managers understand line operation and technical problems, but also promote the interaction and cooperation between line operators and suppliers. Especially in the event of catastrophic events in power supply chain, power managers can more accurately and quickly grasp the line fault situation, quickly carry out spread control and fault repair, reduce the line maintenance cost and improve the stability of power supply. Large-screen visual decision-making system, the digital age has come.

The application of 3D visualization technology is bringing new opportunities and challenges for intelligent management and digital upgrade of power transmission lines. In the future, the development of three-dimensional visualization technology of power transmission lines will become more and more intelligent, convenient and efficient, helping power managers to better fundamentally solve the difficult problems in power supply chain.

The fiery football season is on! Three national football matches settled in Rizhao.

The remaining temperature of the 2022 Super League still exists, and the hot-blooded football season of Rizhao International Football Center reignited in 2023. The reporter learned from Rizhao Sports Bureau that the women’s Super League of China Football Association in 2023, the women’s U16 of the second China Youth Football League in 2023 and the men’s U19 of the second China Youth Football League in 2023 were settled in Rizhao.

It is reported that at 15: 00 on March 12th, in the third round of the Women’s Super League of China Football Association in 2023, Shandong Sports Lottery Women’s Football Team will play against Beijing Women’s Football Team at Rizhao International Football Center. Shandong Sports Lottery Women’s Football Team was established in November, 1983. It is one of the provinces that launched women’s football and established women’s football teams earlier in China, and it is also a key area for the development of women’s football in China. The level of women’s football in Shandong Province was in the leading position in the whole country, and it achieved excellent results in the national women’s football competitions for many times. The match between Shandong Sports Lottery Women’s Football Team and Beijing Women’s Football Team is the first home game of Shandong Team in the Women’s Super League this season (the other home games are held in Shandong Sports Center Stadium in Jinan).

"Tell me about …"

Today, there are many unique games that can be experienced on consoles and PCs. Although there is a lot of information available about which games are the best, sometimes our tastes and our moods may be more specific. Bing can also help you extract from the appearance of the game, the characters in the game or the time it takes to complete. Here are some examples of your own attempts:

  • "Tell me the best Cyberpunk-style role-playing game on Xbox."

  • "Tell me about the best action game that lasts no more than 10 hours."

  • "Tell me the best heroine game on Xbox."

"What is the best _ _ _ _ _ for me?"

There are various shapes and sizes of game strategies, and it is not difficult to find opinions on what is the best equipment load, role and skill tree selection. But are they your best choice? You can start with a basic question, but the subsequent interaction will let Bing guide you to make the best choice, understand how to configure it, and even see which games.

This is what we asked:

"Where can I find …?"

Bing can help you find many things in your favorite games, such as the location of each secret weapon in Fortnite, the location of Tall Tales periodicals in the Sea of Thieves, and it can even help you find your car keys (to some extent). But what if you don’t immediately think of what you are looking for? Do you know the type, for example, that person once did the task with a flaming sword? In order to start in-depth research to help us find the correct answer, we put forward the following questions:

  • "Where can I find the blue alien lady in mass effect 3?"

  • "Where can I find a list of Radiation 3 tasks starting with the letter J?

  • "Where can I find the task of the man who used to do that with a flaming sword?" Your follow-up reply is very important for this kind of thing! )

"Give me a review …"

In addition to the incredible world, games can also have complex and developing storylines, which seems a bit difficult to understand when playing games. Not to mention that we must put down the controller at some point and continue the operation another day. Sometimes that day will turn into months or even years. So, wouldn’t it be nice to review your progress in the game without starting over? New Bing is ready to help you. Here are some examples we have extracted from it:

  • "Give me a review of Chapter 4 of The Kingdom of Two: The Queen of White Ashes."

  • "Give me a review of the contents of the wizard after 3 20 hours."

  • "Give me a review of every battle story in the Halo series."

"How can I …?"

Although Bing can definitely help us learn how to beat the worst bad guys in the game (for example, "How do I beat Malenia in Elderring?" ), but we want to take it in a slightly different direction: what if it can help us? Learn how to create tangible things from our favorite games. After all, learning how to do new things may be one of the most interesting things in life, so much the better if it comes from our favorite game world! Therefore, we solve this problem through some examples that you can also try:

  • "How do I make cakes that appear in the Portal?"

  • "How can I make a toy sword according to the design in the sky?"

  • "How can I prepare a meal according to Lamian Noodles’s recipe in Dragon 7?"

Is the travel and accommodation industry under the ChatGPT craze a slogan or a gimmick?

In the past February, many travel enterprises gathered together to apply ChatGPT, and the craze about ChatGPT is accelerating in generate. However, the controversy also started quickly. Some people say that ChatGPT is a slogan, while others say that it is a gimmick. What kind of picture will it be when ChatGPT-like applications "enter the circle" to travel?

This February and March belongs to ChatGPT.

In the past February, many travel companies got together to apply ChatGPT. On February 15th, Ctrip announced that it had become the first batch of ecological partners of Baidu Wenxin Yiyan (English name: ERNIE Bot). The Qunar platform has launched the intelligent question-and-answer robot "Universal AI Camel" of Chat GPT, which helps users to customize their itinerary and answer problems in travel. The included questions cover the recommendation of tourist routes, toilets in scenic spots, and eating mushrooms by mistake.

On February 28th, Wuxi Cultural Tourism Committee announced that it had become the first batch of ecological partners of Baidu Wenxin Yiyan. In the follow-up, the Wuxi County Cultural Tourism Committee will fully experience and access the ability of Wenxin to say a word through Baidu APP. On the same day, Chongqing Wulong District Cultural Tourism Commission also announced that it had become the first batch of ecological partners of Baidu Wenxin Yiyan, marking the first landing of dialogue language model technology in various scenic spots in Wulong.

In March, Wenxin will soon be open to the public. The craze of ChatGPT is accelerating generate.

However, the debate also started quickly. As far as the current version of ChatGPT is concerned, in the repeated tests of users, ChatGPT has many problems such as common sense dislocation, data distortion, fabrication of false information, etc., which are regarded as its undeniable weakness.

Some people say that ChatGPT is a "window", and some people say that ChatGPT is just a "gimmick". Looking forward to the future, what kind of picture will it be when ChatGPT-like applications "enter the circle"?

01 ChatGPT is just frying cold rice?

If we say that the products represented by Metauniverse provoked the industry’s emotions in the past year, then at present, ChatGPT seems to be "popular".

However, looking at the domestic travel agencies and enterprises that have entered the market, it seems that the application at this stage is more at the customer service level, such as the intelligent question-and-answer robot of Qunar platform.

Intelligent customer service has been popular in China for many years.

In the 1990s, the Internet was not popular, customer service was mainly based on telephone communication, and call center was mainly based on hard switching technology.

In 2000, the Internet began to spread, traditional customer service software entered large enterprises, and call centers based on softswitch technology appeared.

Around 2010, technologies such as mobile Internet, cloud computing and big data began to be applied, and cloud call centers and cloud customer service software based on SaaS appeared.

Even the latest online "Universal AI Camel" is not new. As early as 2017, AI customer service camel has already appeared in the business innovation where to go.

Empowered by a new generation of AI technology, the customer service system is integrated with the Internet, and an innovative intelligent service model is introduced into the customer service center.

The waiting of "busy human seats" seems to prove the limitations of intelligent customer service. Although ChatGPT has the learning ability, it is still necessary to establish a very detailed and in-depth knowledge map in customer service, which is far beyond the content that search engines can provide.

Therefore, even though ChatGPT has achieved a good effect of man-made dialogue, from the practical application of cultural tourism, it is still only a new form of intelligent customer service, and the form is greater than the content. This means that from the current stage of development, for OTA platforms such as Ctrip and Qunar, which are represented by standardized products such as machine wine and tour group agents, the application scenarios of ChatGPT will be even bigger, while for non-standard products or customized products such as B&B, it seems that there are still many problems to be solved urgently.

02 ChatGPT public opinion fever may have ended, and the core issues have begun to stand out.

Baidu index shows that the search popularity of "ChatGPT" reached its peak on February 8, and then it fell off a cliff. It seems that the internet giants have gathered together to enter the market with great vigour.

As mentioned above, although ChatGPT, as a generative AI, has mobilized a lot of capital and talents, the public’s cognition, the underlying logic of application and the development of AI cannot advance by leaps and bounds.

This also means that the ChatGPT public opinion is likely to have ended. On the other hand, the core issues of development have gradually become prominent.

First of all, the meta-universe was popular for a while in 2022, and ChatGPT was popular after the opening of 2023. Many technologies still need to be optimized, and the gap between intelligent question answering and manual service still exists. As a typical non-standard product, B&B is a more representative case.

Traditionally, non-standard products and services provided by Minsu are still necessary for human customer service, in order to understand and clarify complex problems or satisfy the desire for "human touch", regardless of waiting time. As a natural "tour guide", especially for the landlord who provides landlord friendship service, the personalized landlord service needs more information input and learning from AI. Comparatively speaking, Muniao B&B and Meituan B&B with more experience in C-side operation will be better databases.

To give an inappropriate analogy, if you want to completely replace labor, ChatGPT is like a foreign candidate in the CET-4, and the challenge you have to face is not just the "meaning" in the simple Chinese exam. This is why Booking is in no hurry to apply generative AI to the platform.

When A Dai gave the leader a red envelope, the conversation between them was quite interesting.

Leader: What do you mean?

A Dai: Nothing interesting, just interesting.

Leader: You are not interesting enough.

A Dai: Nothing, nothing.

Leader: You are really interesting.

A Dai: Actually, there is no other meaning.

Leader: Then I’m sorry.

A Dai: I’m sorry.

Leader: You must mean something.

A Dai: It’s really boring.

Leader: Since it doesn’t mean anything, what do you mean?

A Dai: Actually, what I mean is to think.

Leader: Since you mean what you mean, that means what you mean.

A Dai cried: I just wanted to mean it. However, there is really no other meaning. What’s the point of such a small red envelope? It’s just meaning.

The leader smiled: Hehe. I’m a little interested in you.

A Dai le le: hee hee. That’s what I’m saying.

Secondly, ChatGPT is a subversion of the old system. Before ChatGPT, the search was all realized by keywords. For example, I want to know which hotel in Chongqing is good, and directly search the city+location. After ChatGPT, I can directly ask which hotel has characteristics, is cheap and has quality, and has few bad reviews. Once the search method changes, the whole logic of search changes.

It is not easy to land, so we should "give priority to me"

However, we should also see that whether the big manufacturers get together to enter ChatGPT, or the participation and wait-and-see in various fields at present, it means that the generative AI including ChatGPT will continue to become a trend for a long time to come.

Since 2019, the technology of "AI+ Cloud" has been continuously explored. Whether it is Ctrip’s personalized recommendation supported by artificial intelligence or the refined operation of Wooden Bird B&B, it is essentially to meet the needs of users, that is, "me".

In July 2022, Suzhou Municipal Bureau of Culture, Radio, Film and Tourism released the first batch of 10 representative application scenarios of "AI+ Cultural Travel" in Suzhou.

With the algorithm breakthrough brought by ChatGPT, AIGC knocked on the door of AI to the new world. According to the analysis of western securities, 2023 is expected to be a great year for the development of AIGC, and the market outlook is expected to create a market exceeding one trillion yuan. The breakthrough of ChatGPT also means that AI has begun to move towards the development path of creating new content.

Therefore, on the whole, even if the popularity of openAI goes calm with the opening of ChatGPT, the development of AIGC still has great capital attraction and subversive innovation.

Fang Tengfei, vice president of Tencent Cloud and general manager of the cultural tourism industry, believes that with the change of the entrance of tourism consulting and booking services, the form of tourism products will change accordingly, from standardization to customization. Provide more personalized solutions in a low-cost and efficient way. In order to obtain a more general and easy-to-use model, more domain-related data accumulation and algorithm innovation are needed.

Learn what? Accumulate what? "I" has already performed. In 2018 and 2019, Ctrip’s iOS download volume was stable at around 10W, with the highest download volume per day of 24W+, and it was stable at around 4W in recent years. Even in the Spring Festival of 2023, when the recovery volume was amazing, the download volume per day was at 5W+, and the number of new users was seriously attenuated. Flying pigs and going anywhere show similar development trajectories.

Therefore, OTA, ticketing platform and so on contribute more to the old user data, and the conversation data is traditional, but standard and rich. As Liam Fedus, a researcher at OpenAI, said, observing the rich and innovative application scenarios provided by users, through the iterative process of deployment, feedback and continuous improvement, we can produce the most demanding and powerful technology. The user data of the B&B booking platform is more innovative, which tends to be more experiential.

In the summer of 2022, the maximum download volume per day reached 2.1W+, which once approached the OTA platform. Emerging cultural tourism products such as homestay, intangible cultural heritage, recreation and vacation have more trainability.

In terms of categories, OTA platforms, hotels, scenic spots and other fields with higher standardization will be accessed faster in a short period of time, but the characteristics of generative AI are destined to be customized trips and more personalized B&B tours in the future, as Fang Tengfei said. There will be deeper exploration space.

The contemporary needs of self-occupation, self-driving, personalization and diversity require general AI capabilities such as ChatGPT to create more consumption scenarios to meet the high-quality development driven by the supply side. Platforms that have been deeply cultivated on the supply side for many years, with more houses and more characteristics, will have more growth potential, such as Muniao B&B. However, how to prevent abuse and the discussion of copyright and originality that comes with it is also a problem that must be solved in future generative AI.

Just as booking is worried, only by solving the application scenario of the product itself can players have the "capital" to consider how to infiltrate these more mature AI into the B-side and consumer experience.

[A little information] The goal machine is now the top scorer in Barcelona, and the World Footballer of the Year without the Golden Globe Award.

The Polish storm, one of the top ten divine winds in football, struck. lewandowski, the log center, the first-half bomber of the Polish goal machine, the top scorer in Barcelona, and the world footballer of the year without the Golden Globe award, Levan’s best friend was Royce, and the two of them all smiled at each other and became a classic.

However, the person that Levan missed most was Gezer. In those days, Levan shot and hit Gezer with one foot, and it was not until Gezer gave birth to a child that Levan was relieved. Strong body, keen sense of smell, can be a fulcrum, can score goals, especially in some less important games, can always kill the quartet, Mr. Small Scene deserves it. When you take part in important competitions, because you attach great importance to the wrist, your feet will become soft and spiritual, so you are called the soft feet of the competition by fans.

If you don’t believe me, in the semi-final of the Champions League in 1913, Dortmund played against Real Madrid, and Levan staged an unprecedented big four-happiness, defeated the Galaxy battleship with Cristiano Ronaldo, and finally won the runner-up in the Champions League with Bayern. It doesn’t matter if you can’t beat them. If it’s a big deal, join them and fight with their old club. In 1914, Lewan switched to Bayern Munich, Dortmund’s friendship team. What can I do in nine minutes? Maybe some people can eat five hamburgers in a row, and some people can bite five people in a row, but Levin gave an answer that shocked the world.

Bayern against Wolfsburg, Levin scored five goals in nine minutes, and became famous in the First World War of the Ninth Five-Year Plan. Guardiola became a little girl and touched her hair excitedly, but unfortunately she didn’t touch it, so the monks who circulated in the workshop were puzzled. Levan’s goal left Guardiola scratching his hair. In fact, what makes Guardiola unable to touch his hair is Sterling, who runs happily like a duck with a belly and a butt.

It’s just that Levan surprised Guashuai, and Sterling easily caused Guashuai’s cerebral hemorrhage. Levan scored five goals in nine minutes, Lu Kaku missed the goal three times, and Moraca was offside six times in five games, which was called the three wonders of single set. During the 1999-2000 season, Levin made 47 appearances and scored 55 goals and 10 assists. In 2020, Levania C Rovesy won the World Footballer of the Year. Unfortunately, the Golden Globe Award was cancelled that year, and the Poles missed the Golden Globe Award. It is a pity. Besides sports, Levan is also the best penalty shooter in football, especially when FIFA World Cup Qatar 2022 and Poland played against France. For the first time, Levan was saved by Lori with his soft and rhythmic footwork, but because Lori moved ahead of time, Levan got a heavy penalty. The second time, Lori moved ahead in the same way, and Lai Wan used the same way to score the ball, which improved the number of goals scored in his World Cup. 100% one goal is promoted to two goals.

In 2002, Levan returned to Barcelona and bluntly wanted to win back the Golden Globe Award. Unfortunately, Barcelona was not the same as Barcelona in that year. FIFA World Cup Qatar 2022 and Poland played against Argentina, and Levan performed poorly and scored zero goals, so Wanzi never dropped the chain in the contest. The picture of Lionel Messi is not only thought-provoking, but it is the strength of Bayern that makes people mistake Lionel for the strongest in the world, or the invincible of Lionel Messi that makes Barcelona feel invincible in the universe. In short, there is not much time left for Wanzi. I hope he can break out again and get the Golden Globe Award without regret. It’s really impossible to join the next door and give it a try. After all, it’s not unheard of to join a sworn enemy.

Improvement of lung cancer staging by PET AI model

A research team in Germany said that an artificial intelligence (AI) model based on routine data of F-18 FDG-PET/CT scanning can improve the accuracy of staging treatment for patients with metastatic lung cancer.

A research team led by Dr Julian Rogasch of Charette Medical University in Berlin has developed a machine learning tool to help evaluate mediastinal lymph node metastasis in patients with non-small cell lung cancer (NSCLC). They found that the model was more accurate than the visual score of PET, and suggested that it could help doctors make more accurate treatment plans. Their results were published in the February 23 issue of the European Journal of Nuclear Medicine and Molecular Imaging, and they wrote that the model can be used as a network application to further promote verification.

Dr. Rogasch and his colleagues wrote: "This model was developed for routine clinical care, and the probability of N2/3 disease (that is, whether there is N1, N2 or N3, which is the key to determine stage II and III diseases) was estimated according to the results of F-18 FDG-PET/CT. This is based on routinely available variables, most of which are already part of the F-18 FDG-PET/CT report in routine clinical nursing. "

In patients with non-small cell lung cancer, accurate imaging of thoracic lymph node metastasis is very important for treatment planning. The authors explain that patients with N0/1 disease usually need surgery, while patients with more extensive N2/3 disease need multimodal treatment. They pointed out that although F-18 FDG-PET/CT is the most effective method, it may be limited by false positive results, and invasive biopsy is often needed to confirm suspicious cases.

In order to evaluate the value of AI model designed to assist these cases, the researchers collected data of 491 patients with non-small cell lung cancer, who were imaged before treatment with analog PET/CT scanner or digital PET scanner. According to the scanner used, patients were divided into training queue and verification queue. There were 385 people in the simulation training and testing queue and 106 people in the digital verification queue.

Forty clinical variables, tumor features and image variables, such as F-18 FDG radioactive tracer uptake (SUVmax) of lymph nodes, were collected, and different combinations of variables in several machine learning methods were compared. The researchers chose a gradient enhancement classifier with 10 eigenvalues as the final model.

The above picture comes from a 54-year-old woman in a training and testing cohort, suffering from G2 adenocarcinoma in the right upper lobe (44 mm). The uptake of F-18 FDG in several hilar and mediastinal lymph nodes was higher than that in normal liver (PET score was 3). The blue arrow shows N2 paratracheal lymph nodes with a short axis of 7 mm and an SUVmax of 3.5. According to the visual assessment, this case is suspected of N2 disease. According to the gradient enhanced classifier model, the probability of N2/3 is only 0.17. Ultrasound-guided bronchial puncture biopsy of LNs at the same hilum, paratrachea and carina confirmed that the patient was NO. Image provided by European Journal of Nuclear Medicine and Molecular Imaging through CC BY 4.0.

The gradient-enhanced classifier model shows that the AUC in the training and testing queue is significantly higher than the visual PET score (0.91 vs.0.87, p=0.003), and the AUC in the verification queue is slightly higher (0.94 vs.0.91, p=0.023).

It is worth noting that the gradient-enhanced classifier model is superior to the visual evaluation of radioactive tracer uptake in lymph nodes above mediastinum, which is the most common and effective diagnostic threshold in visual F-18 FDG-PET/CT evaluation. They also reported that the coordination of PET images between the two scanners does affect the visual evaluation of SUVmax and lymph nodes, but it does not reduce the AUC of the model.

In order to facilitate further verification, the team has published all variables and machine learning codes as open data and used a web application on GitHub. The network application requires users to input 10 eigenvalues to calculate the prediction probability of N2/3 disease.

Dr. Rogasch and his colleagues said that the research results show a good prospect and deserve further study.

They concluded: "We look forward to the external verification and validity proof in the intervention test."

7-0 Manchester United lost its character? Liverpool’s first battle created 7 big shames! Missed the first four opportunities to return, or suffered five consecutive defeats.

In the focus battle of the 27th round of Premier League, which ended on the evening of March 11th, Beijing time, Liverpool lost 0-1 away to Bournemouth, the bottom team, and the good momentum of unbeaten five rounds ended. In the last round, Liverpool beat Manchester United 7-0 at home, which once made people feel that the Red Army was finally back on track, but perhaps the last victory used up Liverpool’s good luck, but this campaign has once again returned to the previous performance of this season. In the face of Bournemouth, who won 9-0 in the first leg, Liverpool was helpless in front of the other side’s iron drum array. On the contrary, Van Dyke’s defense line was distracted again, making it easy for the opponent to counterattack the goal, and Salah, who scored a high penalty percentage, rarely kicked a penalty.

But this campaign lost to Bournemouth, and Liverpool also created a number of shameful records. First of all, Liverpool’s 7-game winning streak against Bournemouth ended, and the Premier League lost to its opponent for the second time.
