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...

The paper analyzed China's modern rural logistics situation and proposed 23 evaluation indexes from seven aspects to establish an evaluation index system of modern rural logistics construction, and finally applied Analytic Hierarchical Model (AHM) to calculate the importance weight of each index in the evaluation system, which provided basis for decision making of building a modern logistics system...
At present, knowledge has become an important capital for many organizations in the international competition. So knowledge management is gradually becoming the core competence and key of sustainable development for organizations. Many enterprises have already used concepts and methods of knowledge management for operation and achieved remarkable results. Based on the analysis of knowledge management...
The core of fuzzy comprehensive evaluation is membership degree transformation. But the existing transformation methods should be questioned, because redundant data in index membership degree is also used to compute object membership degree, which is not useful for object classification. The paper applied an improved algorithm for membership degree transformation in fuzzy evaluation on urban green...
Investment risks assessment of high-tech projects is a more complex process, involving various factors and it is not entirely the linear relationship between influencing factors and measurement results. Artificial neural network (ANN) has a strong nonlinear mapping ability, with strong learning ability and high classification and prediction accuracy. The paper applied ANN to establish a new risk assessment...
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.
The competition among enterprises have been transformed for the competition among supply chains, so it is very important to establish and maintain the cooperative relations in supply chains for enhancing competitive advantages. In this paper, through the game analysis of supply chain suppliers and core enterprises, we can draw the following conclusions: the establishment of the supply chain full cooperation...
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...
