This paper presents a prediction model to predict biogas production for anaerobic digestion process of food waste. There exist sophisticated biogas production models in published literature, but the application of these models in anaerobic digestion process of food waste is often impractical because of its high complexity. Considering the shortcomings of the accuracy of these biogas production prediction...
Existing clustering algorithms need to specify the number of clusters and to select initial points using human input, which lead to inferior clustering and optimisation outputs. Here, an improved grey decision-making model based on the thought of affinity propagation algorithm and grey correlation analysis is proposed to solve these problems. According to the panel data class and the inter-class candidate...
Solving linear equations is key in many scientific research and engineering computing, in order to solve effectly large-scale linear matrix equalities, the traditional algorithm for solving linear equations is analysed and iterative methods is introduced to improve efficiency and reduced storage and algorithm simple. The methods suggested conjugate methods is an effective in storage and compution.
Harmonic wave is harmful to electric power system and equipment. In this paper a harmonic parameter estimation method based on ESPRIT (Estimating Signal Parameter via Rotational Invariance Techniques; ESPRIT) method is proposed. This method is able to depress noise and has better differentiation capability and estimation precision and stability. Design based on DSP of the harmonic detection test device...
Series capacitors compensations may cause subsynchronous resonance (SSR) of steam turbine-generators. Using the principle which is depressed SSR by STATCOM and choosing appropriate measured data to design the subsynchronous damping control (SSDC) based on improved particle swarm optimization algorithm which is presented in this paper. Regard the controller parameter of STATCOM as adaptive parameter...
Data updating is a significant stage in the life of a geographical information system (GIS). When the fundamental GIS database has been updated by mapping organizations, the updates in it should be delivered in time to the end users for updating their own GIS database constructed based on the fundamental GIS database. However, at the present time, the updating service of fundamental GIS database is...
