1 dzień temu · Richard Feynman in 1984. In theoretical physics, a Feynman diagram is a pictorial representation of the mathematical expressions describing the behavior and interaction of subatomic particles.The scheme is named after American physicist Richard Feynman, who introduced the diagrams in 1948.The interaction of subatomic particles can be complex and difficult to understand; Feynman diagrams give a ...
8 godz. temu · In differential geometry, a Riemannian manifold (or Riemannian space) (,), so called after the German mathematician Bernhard Riemann, is a real, smooth manifold equipped with a smoothly-varying family of positive-definite inner products on the tangent spaces at each point .. The family of inner products is called a Riemannian metric (or a Riemannian metric tensor, or just a metric).

(If the image is opened in the Wikimedia Commons by clicking twice on it, cycles can be highlighted by hovering over or clicking on them.). In mathematics, the quaternion number system extends the complex numbers.Quaternions were first described by the Irish mathematician William Rowan Hamilton in 1843 and applied to ...
8 godz. temu · A dissimilarities matrix for the 15 macro-environmental variables was calculated using the Euclidean distance measure. The resulting 72*72 (eighteen countries times four time periods) matrix served as input to a multidimensional scaling routine.

This method ... a mathematical system model and problem formulations of task allocation and load balancing in the cloud using formulas and symbols, to enable efficient resource utilization and optimize system performance ...
8 godz. temu · Among the traditional approaches, matrix factorization is the primary method for learning user embeddings. SocialMF and SoRec have achieved notable performance by decomposing the rating and social relationship matrices to obtain user embeddings. Generally speaking, MF-based methods incur high computational costs due to the need for matrix ...
1 dzień temu · Quantum entanglement is the phenomenon of a group of particles being generated, interacting, or sharing spatial proximity in such a way that the quantum state of each particle of the group cannot be described independently of the state of the others, including when the particles are separated by a large distance. The topic of quantum entanglement is at the heart of the disparity between ...
