In this paper, we principally introduce the concept of quasi-principally κ-projective semimodules, on the basis of the theories of k-projective semimodules and
In this paper, we shall introduce and characterize simultaneous quasi-Chebyshev (and weakly-Chebyshev) subspaces of normed spaces with respect to a bounded set
Quench is important and dangerous to superconducting RF cavities. This paper illustrates the mechanism of quench and how a quench detector works, and analyzes t
