Free settling tests, small angle light scattering (SALS), microtome-slicing techniques, and confocal laser scanning microscopy (CLSM) were performed to examine how the cationic flocculation or freezing and thawing affected the floc structure. The floc size, internal pore size, mass fractal dimensions determined from free-settling test or small angle light scattering test, aeral porosity, bounda...

Biomethanation and dewaterability characteristics of primary sludge (PS), secondary (SS) mixed (MS) fractions were assessed after anaerobic stabilization under parallel batch continuous mixing conditions at 35℃ in order to investigate the performance separate digestion system. Similar methane conversion/yield values obtained PS, SS MS with mixing’s positive effect only PS digestion. Continuous ...

Automatic post-editing (APE) for machine translation (MT) aims to fix recurrent errors made by the MT decoder by learning from correction examples. In controlled evaluation scenarios, the representativeness of the training set with respect to the test data is a key factor to achieve good performance. Real-life scenarios, however, do not guarantee such favorable learning conditions. Ideally, to ...

Batch normalization was introduced in 2015 to speed up training of deep convolution networks by normalizing the activations across the current batch to have zero mean and unity variance. The results presented here show an interesting aspect of batch normalization, where controlling the shape of the training batches can influence what the network will learn. If training batches are structured as...

The sedimentation behavior of fine grained soil is largely dependent on its pore fluid chemistry. Physicochemical properties of the pore fluid, such as ionic strength and pH, could greatly influence the micro structure of kaolinite which in turn influences the sedimentation behavior. Other than ionic effect, adding fly ash can also cause different sedimentation behaviors due to the change of gr...

Background: Various chemical, physical and biologic treatment methods are being used to remove nitrogen and phosphorus from wastewater. Sequencing batch reactor (SBR) is a modified activated sludge process that removes phosphorus and organic material from sanitary wastewater, biologically. Methods: This study was conducted in 2016.The performance of an aerobic-anaerobic SBR pilot device, locat...

Sequencing batch reactor (SBR) technology has found many applications in industrial wastewater treatment in recent years. The aim of this study was to determine the optimal time for a cycle of the sequencing batch reactor (SBR) and evaluate the performance of a SBR for petrochemical wastewater treatment in that cycle time. The reactor was operated with a suspended biomass configuration under ae...
