What is Blender Blender is an open source 3D modeling program, which I have been learning in order to use digital painting MattePainting techniques in creating short films, such as asset creation and 2.5D compositing in scene widening, and the corresponding commercial modeling programs are Maya, 3DCoat, 3dsMax, SideFx, Houdini. The advantage of Blender over commercial modeling programs is that first, it is an open source program, and second, the whole modeling system has a self-contained workflow, from modeling, mapping, bone binding, animation, compositing, and rendering output, all can be done in Blendr. The current version of Blender has been in continuous iteration, and the whole system has started to use more and more advanced technologies, such as the use of EEVEE real-time rendering engine, which reduces production costs when making and rendering animations. ...

For a short video please click here About distributed computing projects I first encountered distributed computing projects during my high school graduation, and ran Boinc distributed computing platform on my laptop, the most famous of which is [seti@home](https://setiathome.berkeley .edu), the Boinc platform was developed for this project. The idea of distributed computing is that the master server splits a task into several small tasks, assigns these small tasks to the clients for computing, and sends the results of the small tasks to the master server after the clients finish computing, and the master server aggregates the results of these computations to get the execution results of the task. ...

SIR Modeling The SIR classical model is mainly used in the field of infectious diseases to predict future trends in the number of infections. S[t] denotes susceptible susceptible population I[t] denotes infected population already infected R[t] indicates recovered recovered population Reference: MathWorld: SIR Model Kermack-McKendrick Model Kermack-McKendrick Model The original Kermack-McKendrick model was designed to account for changes in the number of people infected over time, like the plague that occurred in 1665-1666 and the cholera that occurred in 1865. The model assumes that the total population is fixed, that the incubation period for infectious diseases is instantaneous, that the duration of infection is the same as the disease cycle, and that the population is assumed to be non-differentiable, without differences by gender or race. ...
