The biocidal effects of free nitrous acid (FNA) have found applications in multiple units in an urban wastewater system, including sewer networks, wastewater treatment processes, and sludge treatment processes. However, these applications are associated with chemical costs as both nitrite and acid are needed to produce FNA at the required levels. The recent discovery of novel acid-tolerant ammonia oxidizers offers the possibility to produce FNA from domestic wastewater, enabling the development of next-generation FNA-based technologies capable of achieving self-sustaining FNA production. In this study, we focus on the concept of in situ FNA generation facilitated by acid-tolerant ammonia oxidizers and highlight the multiple benefits it creates, after a brief review of the historical development of FNA-based technologies. We will discuss how wastewater systems can be made more energy-efficient and sustainable by leveraging the potential of acid-tolerant ammonia oxidizers.

The activity model of CaO-FeO-SiO2-WO3 quarternary system is built according to the coexistence theory of slag structure and the reduction thermodynamics of scheelite is discussed by using this model. The activities of SiO2 and WO3 decrease, while the activity of CaO increases with increasing the basicity of slag. Among SiC, carbon and silicon reactants, the reducing capability of SiC is the strongest, while that of carbon is the poorest at high temperature （about 1 873 K）. Increasing the content of silicon or carbon is beneficial for increasing the yield of tungsten. Oxidizability of slag has a significant effect on the yield of tungsten. Controlling basicity and oxidizability of slag can decrease the oxidation loss of tungsten.

In this paper, we obtain a lower semicontinuity result with respect to the strong L1-convergence of the integral functionals F（u,Ω）=Ωf（x,u（x）,εu（x））dx defined in the space SBD of special functions with bounded deformation. Here Su represents the absolutely continuous part of the symmetrized distributional derivative Eu. The integrand f satisfies the standard growth assumptions of order p 〉 1 and some other conditions. Finally, by using this result,we discuss the existence of an constrained variational problem.

To overcome the high computational complexity in real-time classifier design, we propose a fast classification scheme. A new measure called 'reconstruction proportion' is exploited to reflect the discriminant information. A novel space called the 'reconstruction space' is constructed according to the reconstruction proportions. A point in the reconstruction space denotes the case of a sample reconstructed using training samples. This is used to search for an optimal mapping from the conventional sample space to the reconstruction space. When the projection from the sample space to the reconstruction space is obtained, a new sample after mapping to the new discriminant space would be classified quickly according to the reconstruction proportions in the reconstruction space. This projection technique results in a diversion of time-consuming calculations from the classification stage to the training stage. Though training time is prolonged, it is advantageous in that classification problems such as identification can be solved in real time. Experimental results on the ORL, Yale, YaleB, and CMU PIE face databases showed that the proposed fast classification scheme greatly outperforms conventional classifiers in classification accuracy and efficiency.
