Trivial stuff - 20090218

本文讨论了当前流行的时尚元素,如皮革制品、毛皮细节镶边的衣服、太阳镜及围巾等,并分享了一位从传统行业成功转型为IT专业人士的经历。文章提供了有关如何通过短期课程和个人实践进入IT行业的建议。

 

Hey Katie, look at these boots I bought. Aren't they fabulous?

Those are great. You must have paid a fortune for them,though.

Not really. They were discounted(vt.vi. 打折) fifty percent. The mall across the street is having a half-off sale on all of the last year's designs.

Maybe I should go. Is that where you usually shop?

Not usually. But I've been looking for boots like these for a while. They're all the rage(in fashion. rage:vi.大发脾气 n.狂怒). Where do you like to go?

To tell the truth, I haven't gone out clothes shopping for a while. So these boots are the "in thing" now? Are they real leather?

100 percent leather. Leather is really in fashion right now. It's amazing how fast trends change.

I know what you mean. I feel like my entire wardrobe(衣柜) is totally out of date. Your clothes are pretty trendy. You always seem to have something new. What do you recommend? How can I change my image?

Well, fur trim(毛皮细节镶边的衣服)is hot right now. And everyone is wearing sunglasses.. And scarves(围巾 披肩), you need to have a scarf.

I go for a more traditional style, I think: simple and classic. That's what I like.

I've tried that before, but "classic" was in about 2 years ago.

So the traditional trend has come and gone?

Yeah, but don't worry, it might come back in style again soon.(也许很快又会流行经典风格的)

Do you have time to go window shopping at lunch. Tha sale is still going on...

Absolutely. I could use a second opinion.(你要帮我参谋参谋)

 

How's the new job?

Changing careers was the best thing I ever did.

Sometimes I think I should get into the IT industry. I've always been a bit of a computer geek..and everyone at my work turns to me when the office computers crash.

Well, IT isn't for everyone, there are so many tech jobs...it's hard to know which fields are for you.

How do I find out?

Evening courses are a good place to start. You can try a few, see which fields you like.

Yeah, that's a good way to pick up the basics. But at some point won't I need real qualifications?f

Maybe, you have a business degree,right? You could combine that with a few short courses. and you wouldn't really need a technical major.

But don't I need practical work experience?

Well you could look other ways to volunteer(vt.vi.自动提供 自愿效劳) your services: building Web sites,helping them use the Internet.

I suppose that's one way to get real experience.

Yeah, IT touches every career sector these days. You can look at ways of combining that with your current job.

Good idea. So how did you break into the IT industry eventually?

After taking a few classes, I decided I wantd to be a network administrator.

I looked at qualifications, career paths,salaries. Six courses,one exam later

I become a certified network specialist

提供了基于BP(Back Propagation)神经网络结合PID(比例-积分-微分)控制策略的Simulink仿真模型。该模型旨在实现对杨艺所著论文《基于S函数的BP神经网络PID控制器及Simulink仿真》中的理论进行实践验证。在Matlab 2016b环境下开发,经过测试,确保能够正常运行,适合学习和研究神经网络在控制系统中的应用。 特点 集成BP神经网络:模型中集成了BP神经网络用于提升PID控制器的性能,使之能更好地适应复杂控制环境。 PID控制优化:利用神经网络的自学习能力,对传统的PID控制算法进行了智能调整,提高控制精度和稳定性。 S函数应用:展示了如何在Simulink中通过S函数嵌入MATLAB代码,实现BP神经网络的定制化逻辑。 兼容性说明:虽然开发于Matlab 2016b,但理论上兼容后续版本,可能会需要调整少量配置以适配不同版本的Matlab。 使用指南 环境要求:确保你的电脑上安装有Matlab 2016b或更高版本。 模型加载: 下载本仓库到本地。 在Matlab中打开.slx文件。 运行仿真: 调整模型参数前,请先熟悉各模块功能和输入输出设置。 运行整个模型,观察控制效果。 参数调整: 用户可以自由调节神经网络的层数、节点数以及PID控制器的参数,探索不同的控制性能。 学习和修改: 通过阅读模型中的注释和查阅相关文献,加深对BP神经网络与PID控制结合的理解。 如需修改S函数内的MATLAB代码,建议有一定的MATLAB编程基础。
