2020.08.29(pm): Data Augmentation
This post was written by referring to the contents of a deep learning book from the founder of Keras. : https://www.manning.com/books/deep-learning-with-python Overfitting occurs when there are too few samples to learn. This is because you cannot train a generalizable model on new data. Given a lot of data, the model can learn all possible aspects…

2020.06.21(pm): Reynolds Transport Theorem
It is very important to know the difference between Euler’s method and Lagrange’s. This is key to a deep understanding of the mechanics problem. Lagrange coordinate system The Lagrange coordinate system is also called the material coordinate system or reference coordinate system. The Lagrange coordinate system is called a material coordinate system because it is…

2020.06.14(pm): fin efficiency and fin effectiveness
Heat transfer is an area that deals with changes in temperature and the flow of heat energy. There are three basic mechanisms of heat transfer: conduction, convection, and radiation. ConductionIt is the transfer of energy from active particles to neighboring more active particles by the interaction of particles in the object. ConvectionHeat transfer between a…

2020.05.24(pm): Finding the diameter of a pipe using hydrodynamics
Good afternoon. I’m thinking seriously about the fluid mechanics issue today. Recently, there is a problem I am trying to solve, and the situation is as follows. Let’s look at the picture. The situation is that after a lubricant flows from a certain facility, it is gathered through two pipes to the collector. However, rather…
