We will derive various view factors for disks and cylinder walls with finite area, based on the analytical view factor from a plate element to a disk.
If two plates with different materials are bonded together, it is called bimetall. Due to the different thermal expansion coefficient (CTE), a bimetallic strip causes deformation by temperature change.
MRG32k3a is one of the common algorithms for random number generation for parallel computing. In this article, we will implement the MRG32k3a algorithm on WebGL2, with skip-ahead functionality.
Analytical derivation of a disk view factor from a plate element, using both area integration and line integration approaches.
Xorshift is one of the simplest and high-speed random number generator (RNG) algorithms. In this article, we explore the concept of Xorshift, and implement Rust code for searching valid Xorshift parameters for 32-bit binary.
Mathematical methods for uniformly distributing points on primitive geometric surfaces including rectangles, triangles, cylinders, discs, spheres, cones, and parabolic surfaces for ray tracing applications.
If you want to calculate the time evolution of ODE, one of the most common and simple methods is the Runge-Kutta method (RK4). In this article, we will confirm that RK4 achieves fourth-order accuracy.
The transformation from ECEF (Earth Centered Earth Fixed) coordinates to geodetic coordinates is a well-known problem in geodesy. For the realistic transformation, the Earth should be approximated by a spheroid, and the transformation in this case is not trivial.
When the interested fluid phenomenon reaches very low density region, we have to be careful whether it is still within the scope of ordinary fluid dynamics. One of the useful indicators to characterize such physical phenomena is a dimensionless quantity called Knudsen number.
Rounding errors are inevitable in floating-point arithmetic. In particular, after multiple operations, how errors propagate is not immediately obvious. In this article, we will look into the floating point definition in IEEE 754-2019 and discuss a basic methodology for the error estimation.
