Complex Envelope Approximate Crank-Nicolson Method and Its Open Boundary Implementation for Bandpass Problem [PDF]
IEEE Access, 2021 To efficiently simulate the bandpass electromagnetic problems by employing the finite-difference time-domain (FDTD) algorithm, unconditionally stable implementation is proposed based upon the complex envelope method and the Crank-Nicolson Direct ...

Mathematical models of the Bandpass problem and OrderMatic computer game [PDF]
Mathematical and Computer Modelling, 2010 A new combinatorial optimization problem, the Bandpass problem, was defined in Bell and Babayev (2004) [4]. Recently, this problem was investigated in detail in Babayev et al. (2009) [5]. In this paper, we first present some new mathematical models of the Bandpass problem. Then related to this problem, we introduce a software called OrderMatic which is

The three column Bandpass problem is solvable in linear time
Theoretical Computer Science, 2010 AbstractThe general Bandpass problem is NP-hard and was claimed to be NP-hard when the number of columns is three. Previously we designed a polynomial time row-stacking algorithm for the three column case, to produce a solution that is at most 1 less than the optimum. We show in this paper that for any bandpass number B≥2, an optimal solution is always

An approximation algorithm for the Bandpass-2 problem [PDF]
CoRR, 2013 The general Bandpass-$B$ problem is NP-hard and can be approximated by a reduction into the weighted $B$-set packing problem, with a worst case performance ratio of $O(B^2)$. When $B = 2$, a maximum weight matching gives a 2-approximation to the problem. In this paper, we call the Bandpass-2 problem simply the Bandpass problem. The Bandpass problem can

A novel detection method applied on low-frequency harmonics of Tokamak power supply
Energy Reports, 2021 Non-characteristic low-frequency harmonics generated by non-linear devices have properties of small amplitude and non-stationary state, and contain complex side-lobe inter-harmonics, which is difficult to achieve the precise and real-time extraction for ...
