This project is a Python package that is intended to support engineers in creating simple process flow diagrams (PFD) from code, without the need for a complex chart drawing tool or CAD program. The main use case is the visualization of flowsheets generated in textual modeling languages / proc...
1.不要new QStandardItem然后tableModel->setItem,让框架自己管理对象,应该使用: tableModel->setRowCount(row); tableModel->setColumnCount(column); 这样model里面会自己new,你只需要setData tableModel->setData(tableModel->index(r, c), "", Qt::EditRole);//效率提升很大 2.->setModel(tableModel);之后...
ProcessDiagramGenerator生成流程图flowable 我们在日常的办公中,经常需要绘制一些流程图,借助这些流程图,除了可以让自己更加清晰地认识到事情的每个细节之外,也可以让其他人知道你的想法。那么,对于流程图的绘制,借助软件会更加方便。接下来就要来和大家讲讲流程图的绘制技巧。 一、绘制工作流程图的好处 1、细分事件 绘...

CRC 验证码是一种基于循环冗余校验(Cyclic Redundancy Check, CRC)的错误检测机制,广泛应用于数字通信和存储系统中。CRC 验证码通过生成一个固定长度的校验值(校验码)来检测传输或存储过程中是否发生错误。 ### 工作原理: 1. **数据处理**:发送方将数据以二进制形式表示,并通过特定的生成多项式对数据进行计算,得...
Fig. 8. Process flow diagram of the partial oxidation process for methanol production used as case study (Julián-Durán et al., 2014) and Stream Safety Index for each stream. Stream Safety Index for each stream is reported in Fig. 9, and every stream index has also been added to the ...
ImagePy is an open source image processing framework written in Python. Its UI interface, image data structure and table data structure are wxpython-based, Numpy-based and pandas-based respectively. Furthermore, it supports any plug-in based on Numpy and pandas, which can talk easily between sci...
Can you describe your business processes with flowcharts? What if you could define the steps in a standard notation and implement the workflows in pure Python? This week on the show, Dan Funk from Sartography is here to discuss SpiffWorkflow.
数据流图(Data Flow Diagram):简称DFD,它从数据传递和加工角度,以图形方式来表达系统的逻辑功能、数据在系统内部的逻辑流向和逻辑变换过程,是结构化系统分析方法的主要表达工具及用于表示软件模型的一种图示方法。数据流图是结构化分析方法中使用的工具,它以图形的方式描绘数据在系统中流动和处理的过程,由于它只反映系...
一、数据流图(Data Flow Diagram,简称DFD) 是一种便于用户理解、分析系统数据流程的图形工具,精确地在逻辑上描述系统的功能、输入、输出和数据存储等,是系统逻辑模型的重要组成部分。 1、基本图形元素元素 (1)外部实体(External Agent) 指存在于软件系统之外的人员或组织。
