The blast furnace gas is an important secondary energy for the iron and steel production. Establishing an effective model to describe the state of BFG system is of great significant to maintain the system balance and stability. Considering the strong coupling characteristics of the blast furnace gas system and the high level noises in the industrial data, a simplex unscented Kalman filter-based Wang-Mendel...
Based on data mining, the main impact factors of urban life water consumption are made gray relational analysis with the water consumption. The main driving factors of urban life water consumption are discussed. By the gray forecasting of the development trends of the main impact factors, a grey prediction of GM (0, N) model on urban life water is established. An instance proves to fit the data better...
Analysis the positive and negative sentiments about each topic of the product are very useful to the customers and manufacturers. In this paper we propose a new topic sentiment mixture model which we call Semi-supervised Co-LDA model to obtain the positive and negative opinions from the reviews about each product. The Semi-supervised Co-LDA can model the topic and sentiment of the product reviews...
In order to mining the organizational setting and interactions among coworkers from workflow logs, we define metrics to establish the relationships among originators by analyzing the information in the workflow logs. Generate relation networks from the workflow logs by applying the handover of work metric. By applying these methods, we can construct the corresponding relation networks which reflects...
The paper studies semi-global practical input-to-state stability (SGP-ISS) of a parameterized family of discrete-time systems that may arise when an approximate discrete-time model of a sampled-data system with disturbances is used for controller design. It is shown under appropriate conditions that if the solutions of the time varying family of discrete-time systems with disturbances converge uniformly...
As one of the candidates of the next generation non-volatile memory(NVM), phase change memory(PCM) has been paid more attention. However, there are still many open issues such as numerical simulation to study. Phase transition is a temperature based process, which can be simulated by temperature profile generated by the device simulator coupled with the phase transition model. In this work, a phase...
The Technical Barriers to Trade (TBT) is an important problem faced to the export of China. Based on the number differences of TBT notifications between countries, we propose the concept and computational method of the technical barrier coefficient. By means of price-production and price-demand functions, a trade model with a developed country and an under-developing country is designed. The available...
This Individualpsilas representative activity-travel pattern is the foundation of analyzing travel time, space and mode. Based on the actual data of 2004psilas resident trip survey in one metropolis of north China, by using the systematic cluster analysis, thousands of citizens are divided into groups with representative activity-travel patterns according to representative social-economic attributes...
The ultimate bearing capacity of single driven pile increases with time after pile installation, and it is of great importance to foundation design. Although various methods have been established to study this time-dependent ultimate bearing capacity of driven pile, they have different occasions for application, and the deduced results of them may differ greatly. In this paper, four typical types...
