RATIONALEAmong the six positional isomers of dihydroxybenzoic acid (DHB), 2,5‐DHB is a more favorable matrix for use in matrix‐assisted laser desorption/ionization (MALDI) than the other isomers because of its high ion‐generation efficiency at 337 and 355 nm. The generation of hydroquinone or p‐benzoquinone through the decarboxylation of 2,5‐DHB has been suggested to play a crucial role in the ion‐generation...
Allocation of time slots for RFID readers so as to avoid collision has been an active research problem in recent years. Various techniques have been proposed and demonstrated with success in small scale reader networks. In this paper, a heuristic algorithm and three simulated annealing (SA) algorithms for solving this problem are studied. Clearly, heuristic algorithm converges faster to a local solution...
