Let's get the paper in Chapter 16 published in SCI journals.
The next day, after finishing his morning "Engineering Drawing" class, Lu Feng declined Zhang Wei's invitation to go to the cafeteria together and headed straight for the laboratory building.
Pushing open the door to room 302, the laboratory was unusually quiet.
There was no noisy banter from Zhou Mingyuan and his friends; only the crisp sound of keyboards echoing in the empty room.
Li Hongde was sitting in front of his computer, staring intently at the screen, his fingers flying across the keyboard.
Hearing the door open, he looked up and saw Lu Feng, a smile appearing on his face.
"You're here?"
"Hello, teacher." Lu Feng put his schoolbag on the computer desk he had used yesterday.
"Where are the senior students?"
"Mingyuan went to the electronics market. The new computers we applied for for our group have been approved. He's going to oversee the assembly and bring the invoices back for reimbursement." Li Hongde picked up his teacup, took a sip, and said, "The rest of the group all have full classes this morning."
Lu Feng nodded; this was pretty much what he had expected.
"Teacher, what tasks do I need to do today?"
Upon hearing this, Li Hongde stopped what he was doing, turned his chair around to face Lu Feng, and looked at him with a mixture of helplessness and amusement.
"A task? You finished all the work I assigned them for the week yesterday morning, and even improved the model's accuracy by two points. Now they have to catch up with you. Where am I supposed to find you a new task?"
Lu Feng felt a little embarrassed by what he said, and he scratched his head.
Li Hongde pointed to the chair next to him.
"Since you're here, don't just sit around. Come over here and help me take a look at these papers and share your thoughts."
Lu Feng sat down as instructed.
On Li Hongde's computer screen, three PDF documents were open, all with English titles.
Research on Gearbox Composite Fault Diagnosis Based on Variational Mode Decomposition and Singular Value Entropy
Nonlinear Dynamics Analysis of Planetary Gear Systems Considering Time-Varying Meshing Stiffness
Application of an Improved Cyclic Stationary Analysis Method in Early Fault Extraction of Rolling Bearings
All of them are cutting-edge journal articles in the field of mechanical vibration and fault diagnosis.
Lu Feng clicked on each article and read them carefully.
"The first paper has a good approach, using VMD to decompose the signal, which is more adaptable than traditional wavelet analysis. However, when calculating singular value entropy, it ignores the coupling effect between different modal components, resulting in a low detection rate for early and subtle faults."
"The model in the second paper is very complete, but it uses an analytical method to calculate the time-varying meshing stiffness. This method is too sensitive to the manufacturing and installation errors of the gears. In practical applications, if the error is even slightly large, the result will be wildly off."
"As for the third one..." Lu Feng tapped the screen lightly with his fingertip, "Its improved cyclostationary spectrum is essentially based on Fourier transform, which inherently has a weakness in processing non-stationary signals. If it were me, I would try to use Hilbert-Huang transform to process it, first perform empirical mode decomposition, and then perform Hilbert transform on each eigenmode function. The resulting instantaneous frequency can more realistically reflect the characteristics of the fault impact."
Li Hongde listened quietly. He had only intended to test Lu Feng's ability to read documents, but as Lu Feng's analysis deepened, his expression gradually became serious.
Every question raised by Lu Feng precisely hit the core weakness of these papers.
Especially the final application of the Hilbert-Huang transform, which is a rather novel and complex nonlinear signal processing method that even many graduate students may not be able to fully understand, let alone undergraduates.
Just how much is this kid hiding?
Li Hongde's mind was in turmoil, but he remained outwardly calm.
Just then, an idea popped into Lu Feng's mind uncontrollably.
Discussing other people's papers is ultimately just theoretical.
Although the learning points given by the system are also increasing, the speed is far slower than solving real-world problems by doing it yourself.
To quickly accumulate learning points, summon the next expert, and exchange for new cutting-edge technology blueprints, you must produce more substantial results.
For example, write your own paper.
He raised his head and looked at Li Hongde.
"Teacher, I have an idea."
"Speak." Li Hongde's attention was completely drawn to him.
"I think we should combine the nonlinear dynamics model we revised yesterday with the theory of fractional calculus and write a paper about it," Lu Feng said.
Li Hongde's hand, which was holding the teacup, stopped in mid-air.
He certainly understood what the direction Lu Feng mentioned meant.
It involves the cross-integration of two completely different but extremely cutting-edge fields, and the difficulty is not as simple as one plus one equals two.
But he didn't immediately dismiss it. Instead, he pondered for a moment and asked, "Have you got an idea?"
"Yes," Lu Feng said.
Li Hongde nodded, seemingly unsurprised by the answer.
"Good, if you have an idea, then go for it. Young people should have this kind of daring and enterprising spirit." He put down his teacup and leaned forward slightly.
"Where should I submit my application? To a domestic core journal, or...?"
Lu Feng interrupted him, speaking in a matter-of-fact tone:
"Let's go with SCI."
The laboratory fell silent instantly.
Li Hongde froze in his chair, slowly turning his head to carefully examine Lu Feng.
A full five seconds passed.
"Well done... just SCI."
A freshman, talking about publishing SCI papers as casually as if he were just going to the cafeteria for a meal.
If this gets out, all the professors at Hong Kong University will probably start to question their existence.
Li Hongde finally couldn't help but laugh.
"Okay, if you have this ambition, of course I support you."
His smile faded, and his expression became serious.
"You write the first draft first, and I'll help you check it. If the article is of high quality, I can help you with the subsequent submission, review, and even writing recommendation letters for the editor."
"Thank you, teacher." Lu Feng felt a warmth in his heart.
"As for the signature..." Li Hongde waved his hand.
"This article, from its core ideas to its specific derivations, is entirely your work. Therefore, you must be the sole first author, and I will not be credited as an author."
Lu Feng was taken aback.
"Teacher, this..."
In academia, it is almost a universally accepted rule that supervisors should be listed as first authors or corresponding authors.
Even worse, many mentors will directly steal the students' core achievements and put their own name first.
Li Hongde, however, voluntarily gave up his right to be credited.
"What is this?" Li Hongde interrupted him.
"I don't care what other mentors' rules are. In my group, Li Hongde's students' future always comes first. This is an honor you deserve. What would it look like if I took it? Would I steal credit from my own student?"
Lu Feng felt a warmth in his heart upon hearing this.
"Thank you, teacher."
Li Hongde accepted his thanks without hesitation and then waved goodbye.
"Alright, stop with the formalities. Just let me see what you can actually write in this SCI paper."
"Don't worry, teacher."
"By the way, teacher, I'd like to borrow some equipment from the lab."
"I signed up for this year's provincial mechanical innovation competition, and I want to use my spare time to build a prototype of my entry."
Li Hongde stopped drinking his tea.
He slowly placed the teacup back on the table, the bottom of the cup making a soft sound as it touched the surface.
Mechanical Innovation Competition?
