Accordingly, the paper studies the final value problem in the field of ODE problems and analyses the differences and relations between initial and final value problems. The more general new concept of the endpoints-value problem which could describe both initial and final problems is proposed. Further, we extend the concept into inner-interval value problem and arbitrary value problem and point out that both endpoints-value problem and inner-interval value problem are special forms of arbitrary value problem. Particularly, the existence and uniqueness of the solutions of final value problem and inner-interval value problem of first order ordinary differential equation are proved for discrete problems. The numerical calculation formulas of the problems are derived, and for each algorithm, we propose the convergence and stability conditions of them. Furthermore, multivariate and high-order final value problems are further studied, and the condition of fixed delay is also discussed in this paper. At last, the effectiveness of the considered methods is validated by numerical experiment.","PeriodicalId":119237,"journal":{"name":"Commun. Stat. Simul.

In this method, the state space model of the EMU brake pad performance degradation is firstly established. And then based on the observed data, the brake pad performance degradation trend is extracted by the fixed interval forward - backward smoothing algorithm. Based on it, the future degradation state can be predicted by Kalman predictor. Based on the obtained state estimation values, abnormal failure tolerance range (AFTR) can be determined applying Grubbs criterion to judge whether the brake pad is being in abnormal state before reaching the final failure or not as a new sample appears. In addition, the cumulative failure probability of the brake pad is estimated in the degradation process. Finally, the thickness data of a certain type of EMU brake pad is applied to predict the future degradation state and determine the abnormal condition, and the result shows that the proposed method is more efficient and accurate.","PeriodicalId":119237,"journal":{"name":"Commun.

In China, the level of regional industry ecological development differs from each other due to different economic level of regions. This paper establishes eco-industrialization index system from aspects of resource consumption, pollution emission, pollution abatement, economic and social development to reveal the connotation and characteristics of industry eco-industrialization, taking Shaanxi Province as an example, and adopts the principal component analysis to evaluate the industry eco-industrialization level of 2001-2015 in Shaanxi. The study shows that the level of industry eco-industrialization in Shaanxi Province is steadily improving, but the environmental protection and pollution control work still needs to be further strengthened. The current development process of industry eco-industrialization still faces hindrances from imperfection of environmental laws, insufficiency of government supervision, shortage of environmental protection planning, high energy consumption and ineffective implementation of cleaner production. Aiming at the hindrances, the paper suggests that Shaanxi should enhance the level of industry eco-industrialization by accelerating the construction of industrial ecological system, establishing environmental planning pilot system, improving resource utilization and promoting the key technological innovation and system integration of industry eco-industrialization.","PeriodicalId":119237,"journal":{"name":"Commun.
