586 | A strategy for a payoff-switching differential game based on fuzzy reasoning | In this paper, a new concept of a payoff-switching differential game is introduced. In this new game, any one player at any time may have several choices of payoffs for the future. Moreover, the payoff-switching process, including the time of payoff switching and the outcome payoff, of any one player is unknown to the ... | [

1028 | Novel approach to super-resolution pits readout | We proposed a novel method to realize the readout of super-resolution pits by using a super-resolution reflective film to replace the reflective layer of the conventional ROM. At the same time, by using Sb as the super-resolution reflective layer and SiN as a dielectric layer, the super-resolution pits with diameters o... | [

1441 | Handles and exception safety, Part 1. A simple handle class | Every C++ program that uses inheritance must manage memory somehow. The most obvious way to do so is directly, but programmers who create complicated data structures often have trouble figuring out what parts of those data structures are safe to delete when. The classical method of dealing with such complexity is to hi... | [
