This chapter will introduce the particle swarm optimization (PSO) algorithm giving an overview of it. In order to formally present the mathematical formulation of PSO algorithm, the classical version will be used, that is, the inertial version; meanwhile
Wukong, the Dark Matter Particle Explorer satellite (暗物质粒子探测卫星), is named after Chinese superhero Monkey King. According to Journey to the West, Monkey King has a pair of sharp eyes which can tell the difference between good and evil. The Wukong satellite is just as sharp-eyed as ...
andαis a coupling constant related to the surface density of the charged elements on the mirror with the dimension of length−1[6]. Having the action at hand, we may then study various issues such as the particle production, the energy flux, the entanglement entropy...
We consider an idealized case of an isolated spherical quartz particle with a concentric, porous carbon shell surrounding the quartz, as shown in Fig. 3. Our geometry consists of three spatial domains. Initially, a solid, impermeable quartz core of radius \(r = R_1\) is surrounded by a ...
Answer to: A bullet of mass 30 g is moving with a speed of 166 km/hr. Calculate its kinetic energy. By signing up, you'll get thousands of...
Taking the local radius, instead of the global radius, as R to evaluate the normal contact response is more representative. Examples of local radius for the sand grains in the study are illustrated in Fig. 4. The local radius of each sand particle was evaluated from two perpendicular ...
It must be noted that the special case of SUI = 1 mainly applies for a homogeneous fluid which is either particle free or contains a particle size distribution where the majority of particles are small compared to the individual opening size. Therefore, we suggest a threshold for the ...

Once again, due to the spherical shape, e.g., sharp corners and small features require very small radii. The explicit time step in DEM is directly dependent on the particle radius and it is most often not feasible with too complex geometries due to this time step dependency. Also, with ...
The strong interplay between experiment and theory relies on confronting precise predictions with accurate data. In the context of high-energy particle physics, the Large Hadron Collider (LHC) and the planned future colliders [1,2,3,4,5,6,7,8] will keep on reducing the experimental ...
