From small town scholar to chief scientist

Chapter 82 The Beauty Tournament Begins

Although the village chief's words were outrageous, Zhou Yi, as a gentleman, couldn't directly ask what gossip was there.

Instead, he asked in a roundabout way.

For example, an elderly widow in Xicun wants to find a wife for a twilight relationship, and everything is settled, so it is only a matter of how to tell the children.

Another example is someone's chicken being confused and eaten by someone else, or a child from a certain family urinating in another family's well.

The progress of the new house at home is faster than Zhou Yi thought,

Grandma's health also began to improve slowly.

Regarding this news, some people said that the medicine of the old Chinese medicine doctor was useful, and some people said that it was because of the success of the Book of Changes. The bad breath that I hadn't uttered at the beginning came out, and it naturally recovered.

Others say it is a combination of the two.

On January [-], the competition officially started.

There are 6 questions in total, each with its own style.

Zhouyi still chose question A,
In the past, the A questions in each year mainly revolved around the simulation of traffic flow, the field of communication, heat transfer, the spread of infectious diseases, and aerospace.

The mathematical models that can be established mainly include: ordinary differential equations, partial differential equations, cellular automata, mechanism analysis, optimization models and mathematical physics modeling.

After the title was downloaded at [-]:[-] in the morning, the QQ voice contact with Tian Yiguang started. As for Xia Xue,
Zhou Yi asked her to come later, these days this girl runs to her house every day.

It's useless to come, anyway, there is an aunt to help make breakfast.

The topics are all in English, but with Zhou Yi's current level of English, there is basically no difficulty.

No translation software is needed, just translate directly.

The general meaning of the topic is as follows:
Develop a model that can be applied to any type of rider, determining the relationship between the position of the rider on the field and the force applied by the rider.

There is a limit to the total amount of energy a rider can expend throughout a race, as well as a limit accumulated from past aggression and exceeding power curve limits.Things to consider:

For a specific length of time, the power curve provides the maximum power a rider can maintain for a given amount of time.

The more power a rider produces, the less time the rider can maintain that power before having to reduce power and recover.

Riders can choose to briefly exceed the limit on the power curve, but the rider needs additional time to recover at lower power levels.

It used to be that a rider's power output was important and as the race went on the rider would get more and more fatigued.

Riders always want to minimize the time it takes to complete a given distance.

These are all the information Zhou Yi obtained from the title,

The question is quite satisfactory for Zhou Yi. After a brief introduction, Zhou Yi also made an outline.

It’s impossible not to list it, there are too many questions, and if you accidentally miss a small question, you will basically miss the O award, let alone the title award.

This time the competitors are not only domestic, but also foreign undergraduates.

Everyone has let their words out, if Zhouyi loses, maybe the Bangzi Kingdom and the Footpen Kingdom will have a face.

Who can stand this?

At least Zhou Yi couldn't bear it, not because of that W.

The first problem is to define the power curves for the two types of riders.One rider should be an expert in timing and the other should be a different type of rider.

The second problem is to apply your model to various timed events; the Olympic Games where the event is specifically called the foot basin, and the time trial of the UCI World Championships in Flanders, Belgium.

A third issue is identifying the potential influence of weather conditions, including wind direction and strength, to determine how sensitive the results are to small differences in weather and environment.

A fourth issue is, presumably, determining the sensitivity of the results to rider bias from the target power distribution.Discuss how to extend your own models.

This year's A question seems to be deviated from the above-mentioned direction, but it actually belongs to the direction of mathematics and physics.

There is also some bias toward decision-making.

After actually analyzing the problem, you will have a clear understanding that it is basically about mathematics.

So in the end it is mathematical modeling, not physical modeling.

In the previous A-questions of the US competition, almost all of them spent their own money to help the ugly country solve some problems.

Gather the global undergraduate elites and a few graduate students to solve some problems in the Ugly Country.

Therefore, many people jokingly say that they spend money to solve problems for their opponents.

But there is no way, the blockade of technology makes people have to find a way to return from their studies.

However, question A has changed this year, which surprised Zhou Yi. This is not to help the ugly country solve the problem, but to help other countries solve the problem, and it is a problem in the past.

This made Zhou Yi feel better.

After Zhou Yi had an idea of ​​the topics and problems in his mind, he began to think about how to build a model.

To stand out from the crowd, you must not choose a model frivolously.

In the past few days, Xia Xue helped make up lessons in the morning and afternoon.

Zhouyi's participation in the global competition has already spread among this group of junior high school students and the whole village.

This made them trust Zhou Yi even more.

A global competition, for them, is so far away, something that they can't even imagine.

For laymen who don't know about Mei Sai, it is of course astonishing, except for 6, it is still 6.

But Zhou Yi is participating in this competition at this moment, and may also get rewards.

This made the villagers even more convinced and respectful.

From the taunting and sarcastic remarks at the beginning, Zhou Yi has now conquered this group of villagers with his strength.

What is strength, this is strength.

Zhou Yi has almost become the idol of children from other people's families in this group of people, and children of all sizes in the village.

As for Xia Xue, she is also a super student. How could she not be able to do mathematics and physics in junior high school? Even in high school mathematics, she can do 140+ at her current level.

There must be something to be able to score 680+ in the test.

As he said before, Tian Yiguang is not a bastard, but he is really capable, at least the art homework is done well.

For Meisai, there must be art modeling.

If some pictures are not beautifully produced, they will not win awards, let alone championship awards such as naming awards.

The exquisiteness of models, programs, papers, and pictures must basically reach the top.

The first three Zhouyi can be solved by one person alone, but things like PS have to be handed over to Tian Yiguang.

Some rules can only be learned to adapt before they have the ability to change.

Mathematics is a subject that pursues truth and beauty, and it must be strictly required.

In one morning, Zhou Yi listed out an idea for all the problems, what method and model to use,

Basically have a number.

For the first question, Zhouyi first established a fatigue physiological model to describe the rider's power curve, which describes the rider's average power output as a function of the sustained output time.

Secondly, starting from the perspective of aerobic respiration and anaerobic respiration, fully considering the energy limitation and the process of energy recovery, a Fa-tigue model of aerobic and anaerobic energy was established.

Then you can use the ordinary least squares method to fit the model, verify the effectiveness of the model, consider different types of riders of different genders, and then you can get the power curve of different riders, and explore the relationship between its characteristics and node parameters relation.

In this way, the first question can basically be perfected.

The writing sequence Zhouyi still plans to follow the steps of the national competition, write the summary at the end, and put the programming after all the models are established.

The programming software still uses MATLAB.

Moreover, Zhou Yi is not going to write a Chinese paper first, and then write an English paper, but write an English paper directly.

At the beginning, Zhou Yi published a lot of SCI papers, coupled with the accumulation of English vocabulary, he has a sufficient level for Zhou Yi to write in English without any pressure.

This time, Zhou Yi wants to let the undergraduates all over the world know who is the emperor among the undergraduates.
