I am using the cluster GRAHAM for our simulation, and it uses SSH (Secure Shell) to connect to the remote servers. It is found annoying to type the password everytime you try to log in or copy files from the server. Herewith several simple commands, we could domake the password-less connection (for MacOS only).

This is simply a list of different Lattice Boltzmann Method-based solvers.

I just implemented the 2D selective filter¹ in Palabos. Because of the non-local calculation when filtering the collision operator, it takes Miguel and me some time to think about a way to implement it in Palabos.

Working on old version software and hardware is not as easy and direct as it seems to be. I am recently trying to set up the Dantec Dynamics CTA hot-wire anemometer. Because the software could only run on Windows XP or other versions in the same era, I have to install Windows XP on the PC of our lab.

In this article, the calling relationship of dynamics would be shown which helps write your own dynamic classes. The dynamics classes are mainly written in /src/basicDynamics/ and /src/complexDynamics/. Here we will take BGKdynamics and MRTdynamics as examples for illustration.

In this article, the execution of data processors and the related functions are briefly summarized, based on the official documentation.

The mode of phonation relates to three factors: breath pressure, airflow, and glottal resistance. The modes could be decided by the glottal resistance which equals the breath pressure by the airflow. The mode could be:

As a 10-year-chorister, this article resolves some of my confusions. Especially what is claimed at the very beginning, there is no difference nor conflict between the training of the solo voice and that of a chorister. Even though, the voice today in modern music conservatories are different from the one of Josquin, Palestrina, or Gesualdo.

This article discusses the relationship between the diction and the vocal technique.
