We present a methodology for implementing digital signal processing (DSP) operations such as filtering with biomolecular reactions. From a DSP specification, we demonstrate how to synthesize biomolecular reactions that produce time-varying output quantities of molecules as a function of time-varying input quantities. Unlike all previous schemes for biomolecular computation, ours produces designs that...
In workflow systems, time performance of workflow instances is key to business management and scheduling. Firstly, the concept of active transition was proposed and its performance equivalent model was analyzed under resources-limited circumstances. Then, the concept of active pattern was proposed and time performances of four basic active patterns were deduced. Finally, an example was given to demonstrate...
Different information retrieval models produce different retrieval results, and have different efficiencies. The paper firstly introduced the basic information retrieval process, and then listed three types of information retrieval models according to two dimensions and their relationships, and lastly gave out related calculation formulas for performance measure of information retrieval models.
For a three-echelon stochastic inventory system in the supply chain, it is difficult to get optimal inventory control policies by analytical methods. The paper sets up an optimization model, which is built on the basis of the discrete event system simulation theory. The simulation-based optimization method is used to solve the problem by combining the simulation model and the particle swarm optimization...
