英语练习79 I want to be a doctor

本文记录了一位孩子表达自己长大后想成为医生的愿望,并解释了原因是为了帮助生病的人。此外,文中还涉及了一些日常对话,如周末计划拜访祖父母等。
我想当医生
母亲:你长大以后想要当什么?
孩子:我想当医生。
母亲:为什么?
孩子:我想要帮助生病的人。


What you want to be when you grow up?
I want to be a doctor.
Why?
I want to help sick people

I will visit[call on] my grandparents this weekend.
I will be visiting my grandparents this weekend
I'm going to call on my grandparents this weekend.
Billy expects to pay a visit to his parents soon
My boss made me work all weekend.
I don't like him because he is bossy
To pass the exam ,you must study.
To master English,you must read English everyday
Instead of studying he played around all day
I rather than he am success

He grew up in the country
My hometown is a small village in the country
基于数据驱动的 Koopman 算子的递归神经网络模型线性化,用于纳米定位系统的预测控制研究(Matlab代码实现)内容概要:本文围绕“基于数据驱动的Koopman算子的递归神经网络模型线性化”展开,旨在研究纳米定位系统的预测控制问题,并提供完整的Matlab代码实现。文章结合数据驱动方法与Koopman算子理论,利用递归神经网络(RNN)对非线性系统进行建模与线性化处理,从而提升纳米级定位系统的精度与动态响应性能。该方法通过提取系统隐含动态特征,构建近似线性模型,便于后续模型预测控制(MPC)的设计与优化,适用于高精度自动化控制场景。文中还展示了相关实验验证与仿真结果,证明了该方法的有效性和先进性。; 适合人群:具备一定控制理论基础和Matlab编程能力,从事精密控制、智能制造、自动化或相关领域研究的研究生、科研人员及工程技术人员。; 使用场景及目标:①应用于纳米级精密定位系统(如原子力显微镜、半导体制造设备)中的高性能控制设计;②为非线性系统建模与线性化提供一种结合深度学习与现代控制理论的新思路;③帮助读者掌握Koopman算子、RNN建模与模型预测控制的综合应用。; 阅读建议:建议读者结合提供的Matlab代码逐段理解算法实现流程,重点关注数据预处理、RNN结构设计、Koopman观测矩阵构建及MPC控制器集成等关键环节,并可通过更换实际系统数据进行迁移验证,深化对方法泛化能力的理解。
Here is an example code for creating a TCP client in Python: ```python import socket # create a socket object client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # get the server IP address and port number server_address = ('localhost', 8888) # connect to the server client_socket.connect(server_address) # send a message to the server message = 'Hello, server!' client_socket.sendall(message.encode()) # receive a response from the server data = client_socket.recv(1024) print('Received:', data.decode()) # close the connection client_socket.close() ``` And here is an example code for creating a TCP server in Python: ```python import socket # create a socket object server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # bind the socket to a server address and port number server_address = ('localhost', 8888) server_socket.bind(server_address) # listen for incoming connections server_socket.listen(1) while True: # accept a client connection client_socket, client_address = server_socket.accept() print('Connection from:', client_address) # receive a message from the client data = client_socket.recv(1024) print('Received:', data.decode()) # send a response to the client message = 'Hello, client!' client_socket.sendall(message.encode()) # close the client connection client_socket.close() ``` Note that in both examples, we are using the `socket` module to create a TCP socket object, and the `sendall()` and `recv()` methods to send and receive data over the connection.
