1.1 This practice covers the optimization of flame atomic absorption spectrometers and the checking of spectrometer performance criteria.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of th...

Estimation of density and hazard rate is very important to the reliability analysis of a system. In order to estimate the density and hazard rate of a hazard rate monotonously decreasing system, a new nonparametric estimator is put forward. The estimator is based on the kernel function method and op...

The optimization policy of the purchase price and the profit under vendor managed inventory (VMI) is studied. For a salable product, supply chain mode of VMI is established, which is based on deterministic demand, having initial stock and having stock-out cost. With the further analysis of the mode,...

Quality of service (QoS) multicast routing has continued to be a very important research topic in the Internet. A method of multicast routing is proposed to simultaneously optimize several parameters based on multiobjective genetic algorithm, after the related work is reviewed. The contribution lies...
