Commencing with the consideration of the topology switching of the 6-pulse bridge, a mathematical framework for small-signal description is established based on switching system theory. By precisely ...
The convergence performance can be well improved by utilizing an adaptive genetic algorithm based on cloud theory. Numerical results based on a typical shipboard power system are used to demonstrate ...
This theory is an extension of that originally proposed by Ulmer 128 who defined this ... In this model, there is a two way interaction, with change at “lower” levels also affecting activity at ...
In practice, computable general equilibrium (CGE) models have been applied to simulate scenarios where geopolitics drives trade fragmentation. A notable example is the use of the GTAP model to assess ...
What lies at the heart of a black hole has puzzled physicists for decades. Now, a team led by physicist Enrico Rinaldi has ...
Michela Buttignol / Investopedia Rational choice theory assumes that individuals make informed decisions instead of random choices. Rational choice theory states that individuals seek to achieve ...
In a new paper published in The Journal of Chemical Theory and Computation, researchers from IBM Quantum and Lockheed Martin ...
Google DeepMind CEO Demis Hassabis had appeared to hint at simulation theory, but he now says that the universe might not ...
The gravitational field—described by Einstein’s theory of general relativity—is a manifestation of the very fabric of reality, spacetime. On the other hand, the Standard Model uses ...
Every healthcare company claims to be working in the patient's best interest, and yet prices only seem to rise.
