We developed a moving window algorithm for wakefield calculations for our SEDG time-domain electromagnetic code NekCEM. When the domain of interest is around a moving bunch within a certain distance, one does not need to carry out full domain simulations. The moving window approach is a natural choice for reducing the computational cost of the conventional low-order methods such as the finite-d...

This paper presents a new algorithm, the Modified Moving Contracting Window Pattern Algorithm (CMCWPM), for the calculation of field similarity. It strongly relies on previous work by Yang et al. (2001), correcting previous work in which characters marked as inaccessible for further pattern matching were not treated as boundaries between subfields, occasionally leading to higher than expected s...

A moving window technique for the finite element time domain (FETD) method is developed to simulate the propagation of electromagnetic waves induced by the transit of a charged particle beam inside large and long structures. The window moving along with the beam in the computational domain adopts high-order finite-element basis functions through p refinement and/or a high-resolution mesh throug...

BACKGROUND Conservative surgical treatment has been the treatment of choice for early breast cancer. It allows feasible oncological treatment with a satisfactory cosmetic approach and fast recovery. However, in some cases mastectomy is necessary. This study proposes a surgical approach with only one surgical access through the same incision, which is in line with precepts mentioned above. It is...
