Jul 18, 2026 John Baez, Endre Bokor and Latham Boyle have a new paper which gets at the Standard Model gauge group and its representation on one generation of fermions starting from a Jordan triple ...
Fill-in-the-blanks for AC commutator motors (universal motors). The core principle is that 'series-wound motors rotate in the same direction even if polarity is reversed, so AC is okay'. This time, I ...
Fill-in-the-blank on structure from the first half of FY2023. This is a re-appearance of the same topic as FY2012 (DC Machines 27). Make sure to memorize the 3-piece set in its entirety. This time, ...
ABSTRACT: This extensive research paper provides a thorough investigation of the algebraic structure of complex products in groups, with comprehensive analysis of both commutative and non-commutative ...
ABSTRACT: In the paper, we study a compressible two-fluid model in ℝ 3 , where γ ± >1 . The pressure of the two fluids is equal. Different from previous research, we consider that viscosity ...
It is now common to say that photons can be transmitted along optical fibers or transmission lines. But in many cases, the transmission pulse is defined by a time profile of the field strength, i.e., ...
Many of our academics speak to the media as experts in their field of research. If you are a journalist, please contact the University’s Media and PR Team: ...
In this paper, we review six fundamental problems encountered by GUR models based on modified commutation relations. A brief overview of the soccer ball problem was given in the previous section, in ...
Abstract: Brushless excitation system was introduced four decades ago to get rid of commutator problems of DC Exciter for turbine generator in power plants. But new problems appeared in rotating ...
Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
The commutator direct inversion of the iterative subspace (commutator DIIS or C-DIIS) method developed by Pulay is an efficient and the most widely used scheme in quantum chemistry to accelerate the ...
