China has enacted the ultra-low emission (ULE) transform in coal-fired power plants. Various studies have focused on model simulation of pollutant variations a national scale, while specific data for concrete generation unit was still lacking. We deployed five-year online collection campaign 660 MW to investigate durative reductions dust, NOx, and SO2, increases removal efficiencies. The result...

China has imposed an ultra-low emissions (ULE) standards policy regarding the emission concentrations of thermal power industry, and region Fen-Wei Plain (China), which is important area blue-sky protection, in urgent need accelerating transformation its units to conform with China’s ULE standards. Based on high-resolution industry inventory, this study used Comprehensive Air Quality Model exte...

Ultralow-energy (ULE) ion implantation is increasingly being explored as a method to substitutionally dope graphene. However, complex implantation-related effects such defect creation and surface contamination, how they can be minimized by thermal annealing, remain poorly understood. Here, we address these open questions taking the model case epitaxial graphene grown on Cu(111), which was subse...

In this paper, we develop a numerically efficient scheme for setmembership prediction and filtering for discrete-time nonlinear systems, that takes into explicit account the effects of nonlinearities via local second-order information. The filtering scheme is based on a classical prediction/update recursion that requires at each step the solution of a convex semidefinite optimization problem. T...

To enhance the transparency of CBO’s work and to encourage external review of that work, CBO’s working paper series includes both papers that provide technical descriptions of official CBO analyses and papers that represent original, independent research by CBO analysts. Working papers are not subject to CBO’s regular review and editing process. Papers in this series are available at http://go....

This paper describes the component in the SUNDIAL spoken dialogue system responsible for semantic interpretation of user input. This component, thèbelief mod-ule', constructs interpretations using several sources of knowledge, including static knowledge deenitions and a dynamic model of dialogue context, and addresses the problem of the hypothetical nature of the recognition and parsing results...
