1.  Your accomplishment and shortage

  (1) Accomplishment

    And complete programming experiment compared for the first time, I learned a lot of things, of which the most is the way to solve the problem and the ability of self-study, when I met something I can't do things, I now know how to self-study and seek help from others, I think it will have a big help to me after work.

 

   (2) Shortage

   In my opinion, I still have a lot of shortcomings, for example, I still cannot complete the construction of the back-end database。

 

 

   (3) The amount of lines I have writed

     I estimate that I have writed almost 4000 lines of code since I started to learn the coding lanuages.

 

   (4) The lab that impress me the most

      Of course, the experiment that impressed me most was lab8 Alpha Sprint. In that experiment, I had no idea at the beginning, and then I made a complete front-end interface. It was a hard process, but I also got a great sense of achievement after completing it. I remember very clearly that week I hardly went to bed before 2 o 'clock and watched the instructional video every day for the assignment.

   (5) The time each operation of software engineering practice take

OperationPercentage
Planabout 15%
Codeabout 60%
Write blogabout 25%

 

    (6) The hours you have spent on soft work practice

     Languages: Phython, HTML, CSS

 

2.Write your own ‘The Mythical Man-Month’, which means write experience summary and case analysis in project practice (e.g., personal project, team project).

    Coding is really hard. No matter how good you are at programming, your ability to learn and your problem-solving experience are the only things that will slow you down. As you get better at the art of programming, you'll be more sure of that. There's another interesting thing about coding

    You'll never get bored with it. If you ever had, you must have done something wrong, too

   The code that has been rewritten may need to be further optimized or abstracted.

   Programming is probably one of the most frustrating things you'll ever do. In general, programming goes through the steps of trying to solve a problem, getting stuck, trying again, stepping back, having an Epiphany, and finally making the program run. It's normal to feel upset, and it won't go away completely. (As you become more adept at programming, you only have to solve harder problems, and the problems may not even be the same.) You should learn to live with this nagging feeling, because it will make solving problems more and more satisfying.

  No matter how perplexing your problem may be, there is always a solution. As your programming skills improve, you'll have more confidence and better solutions. Not only will this improve the feeling of confusion, but it will also push you further to tackle the more difficult problems. (If these things are too easy, they lose the fun!)

 

3.What do you want to suggest and tell the next practice, or for you at the beginning of school, for you in your freshman year, and for Mr. Zhang at the beginning of school? And expectations for future generations. In particular, do you want to change team players in the next term?

To me at the beginning of school:  Please take each of your courses seriously, patiently delve into your major, do not muddle along, indulge yourself. Whenever you are not serious about your study, please think about your future. What you do wrong now, you will make up for in one way or another. In the nutshell, take responsibility for yourself.

To professor Mr.Zhang: Thank you very much for your strict requirements on us. Thanks to your strict requirements, I can write more content on my resume in the future. This allowed me to create one miracle after another that I could not believe myself. Although I complained and didn't understand at the beginning, now I have to grit my teeth and stand until the last moment to understand the truth that pressure is power.

To All the teaching assistances who have been so helpful to me(particularly Mr.Guo) : I would like to thank you very much for your patient guidance and hints in the homework. Your profound knowledge of software engineering makes me admire you and I hope I can surpass you in software engineering in the future.

To our team: To be honest, in programming, my teammate Yang zexuan is very talented and serious, and his guidance and solutions have helped me solve the problems in programming for many times. If there is a chance in the future, I still hope to do co-programming with him.

 

4.Please analyze your team. Software engineering practice is a rare serious team cooperation experience in universities. ‘The construction law’ says that there are several stages of team development. Has your team experienced them and finally reached the "creation" stage?

  I don't think we're at the creative stage yet, because I don't think there's a lot of synergy between our team members.

5. How to prove that you have learned software engineering

【空间辨识】一致模态指标与模态参与因子的随机子空间辨识研究(Matlab代码实现)内容概要:本文研究了一致模态指标与模态参与因子在随机子空间辨识中的应用,重点探讨了如何利用Matlab实现空间辨识方法对动态系统模态参数进行精确估计。文中详细介绍了含噪重复瞬态信号的构成特征,分析了传统信号处理方法如经验模态分解、小波变换和常规变分模态分解在低信噪比环境下存在的模态混叠、端点效应及对瞬态特征识别能力不足等问题。针对这些问题,提出了一种融合变分自适应分解、多谐波特征耦合识别与对偶模式追踪机制的新方法,能够有效剥离噪声、精准匹配并追踪重复瞬态分量。该方法通过四个阶段实现:信号预处理、多谐波特征提取、对偶模式迭代追踪和信号重构优化,显著提升了复杂工况下微弱瞬态信号的提取精度与鲁棒性。试验部分通过仿真与工程实测数据验证了所提方法在不同噪声强度和瞬态形态下的优越性能。; 适合人群:具备一定信号处理基础和Matlab编程能力,从事机械故障诊断、结构健康监测、振动分析等相关领域的研究生及科研人员。; 使用场景及目标:①解决工程实践中被强噪声掩盖的重复瞬态信号提取难题;②提升机械设备早期故障特征识别能力;③为模态参数辨识、状态监测与故障预警提供技术支持; 阅读建议:建议结合Matlab代码深入理解算法实现细节,重点关注多谐波耦合识别与对偶追踪机制的设计逻辑,并通过仿真与实测数据对比分析验证方法有效性。
