Blind source separation (Bss) is one of the most active research areas in neural networks. Previously, we proposed a Bss algorithm which exploited orientation histograms in a joint distribution of observed mixtures. Although the algorithm worked well for simultaneous mixtures of sources, interaural source propagation delays almost always exist in natural environments. In this paper-we extend the algorithm by introducing a bank of band-pass filters and various delays for mixture signals to estimate source propagation delays. It will be shown that the extended algorithm can estimate source delays and separate mixtures satisfactorily. since our algorithm does not contain learning and does not suffer from arbitrariness in permutation of recovered sources as ICA algorithms do, it could be much simpler and easier to construct a real-time Bss system.

sliding mode control (sMC) has been considered as a powerful method for disturbances rejection. On the other hand, we have presented an equivalent-input disturbance (EID) approach to reject disturbances. This paper takes a dual-stage feed drive as an example to compare these two methods. The example shows that, while the EID approach obtains almost the same disturbance rejection performance for matched disturbances as that of the sMC does, it can reject unmatched disturbances. This shows the superiority of the EID approach over sMC method. © 2011 IEEE.

Anisometropia is due to the different refractive power of the left and right eyes, resulting in uneven eye focus and different diopters of the two eyes, resulting in asymmetric hyperopia, myopia and astigmatism. At present, it is not completely clear what causes anisometropia, but it may be caused by different refractive power of both eyes. The difference of binocular refractive power of normal vision people may be as high as 5%, but people with difference more than 5% are prone to binocular vision. The purpose of this study is to measure the changes of clear and blurred brain wave signals of vision. Through the relationship between brain wave signals and visual response, we analyze the attention and meditation curve of brain wave, and complete the fitting prescription lenses of anisometropia. © 2021 IEEE.

The purpose of this study is to develop and investigate a new rough clustering based on optimization. We propose a restructured algorithm using only one variable, instead of the algorithm described using two variables in existing methods. We also perform numerical examples using artificial data and the Iris and Wine datasets. This research has the potential to be used as a method for determining false negatives and false positives in cancer diagnosis.

One key, but little documented and empirically supported, input in the ship design cycle is the expected operating speed profile. This real-world constraint affects many decisions regarding bull form and power systems, from fuel tanks to main propulsion and ship's service machinery selection and operation. These decisions, in turn, ripple through the design of a ship in ways that are often bard to discern, but clearly impact acquisition and life cycle costs. Recent studies of DDG 51 operating speed profiles demonstrate that the Navy regularly operates with speed profiles considerably different than used to design the ship. In general, warships operate in standard engine order telegraph increments (e.g., Ahead 2/3) and at lower speeds than designed for.

Clustering is a typical unsupervised learning method for classifying unsupervised data. One of the clustering meth-ods, even-sized clustering based on optimization (ECBO), is a clustering algorithm that imposes a constraint to equalize the size of each cluster. ECBO has been suggested to be effective in delivery and other problems. However, it is limited to Euclidean space. On the other hand, spectral clustering with a wide range of applicability for partitioning graph data has been proposed. In this paper, we propose even-sized spectral clustering, which imposes a size-equal constraint on spectral clustering, and show that it is an extension of the graph partitioning problem. We also verify the validity of the results through numerical examples.

Recently, there is a new trend to consider wastewater as a precious resource. since phosphorus is a limited non-renewable element, and MAP (Magnesium Ammonium Phosphate - MgNH4PO4.6H2O) is a valuable slow-release fertilizer, the recovery of phosphorous as MAP has received special attention from scientists all over the world. However, the application of this process with municipal wastewater is still a challenge, due to low concentration of phosphorus and high volume of municipal wastewater. This study investigates the potential of reclaiming MAP from municipal wastewater by combination of adsorption and crystallization. soybean milk residue (okara) was loaded with Zirconium (Zr) to prepare the adsorbent (ZLO). Adsorption and desorption experiments were conducted in a semi-pilot scale ZLO packed colum system. Effects of P: N: Mg molar ratios, chemical sources and temperature on the formation of MAP were examined in an attempt to identify the optimal crystallization conditions. The attained precipitate was characterized using XRD, sEM, FTIR techniques. It was found that the ZLO packed column adsorption-desorption system could pre-concentrate phosphorus from municipal wastewater up to 28.36 times, fitting well the minimum requirement (50 mg P/L) for the economical MAP recovery. Up to 95.19% of dissolved phosphorus in desorption solution was recovered at pH = 9, Mg: N: P molar ratio = 2:2:1, using a combination of MgCl2.6H2O and NH4Cl. The harvested MAP exhibited high purity (92.59%), high P-availability (89% by mass), and extremely low levels of heavy metals. The results prove that it is viable to recover MAP from municipal wastewater by employing ZLO as adsorbent, followed by crystallization. This paves the way for mining phosphorus from municipal wastewater and reducing okara as an agricultural byproduct in a green way. © 2019 Published under licence by IOP Publishing Ltd.

A comprehensive study has been made to explore the role of organic acids on electrocatalytic performances of platinum (Pt) nanoparticles supported on carbon porous materials (CPMs) in proton exchange membrane fuel cells (PEMFCs). In particular, the effects of carboxylic acids (R-COOH), viz. formic acid, acetic acid, propionic acid, and butyric acid on catalytic activity, stability, and durability of anodic Pt/CPM electrocatalyst in direct methanol fuel cells (DMFCs) were investigated. In the presence of doped carboxylic acids, the electrooxidative activity of Pt/CPM follows the trend: HCOOH 3COOH 2H5COOH 3H 7COOH, revealing a consistent increase in the severity of catalyst deactivation with the number of carbons on the alkyl chain of the dopant. The Pt/CPM was found to exhibit electrocatalytic performances and tolerance for poisoning than a commercial Pt/XC-72 catalyst with a similar Pt loading (20 wt%). Moreover, a notable increase in mass activity up to ca. 150% over the spent Pt/CPM catalyst was observed up on removing the organic acid in the feed stream, indicating that catalyst poisoning by deactivation may be revived, even to its "intrinsic" activity. © 2013, Hydrogen Energy Publications, LLC.

ssRN 2023年

作者： Phan, Huy N.Q. Leu, Jyh Hoang Nguyen, Vi N.D. Department of Materials Science and Engineering Feng Chia University Taichung40744 Taiwan Master’s Program of Green Energy Science and Technology Feng Chia University Taichung40744 Taiwan Department of Chemical Engineering Feng Chia University Taichung40744 Taiwan

In this study, the treatment of pharmaceutical wastewater was conducted using electrooxidation (EO) and ozone-assisted electrooxidation (EO/O3) with Pt-coated Ti electrodes (Pt/Ti). The removal of chemical oxygen demand (COD), color, and the UV absorption peak at 300 nm (UV300) was investigated in a batch mode reactor. Highly significant quadratic regression models for both processes were revealed through experimental design and optimization using the Box-Behnken Design (BBD) methodology. Current density, initial pH, and electrolysis time were assigned as independent variables for the statistical models. Under optimal conditions of 110.63 A m−2 current density and an initial pH of 4.5 for 477 minutes, stand-alone electrooxidation achieved the removal of 70.5% of COD, 81.25% color reduction, and a 40.01% decrease in UV300. In contrast, ozone-assisted electrooxidation performed even more effectively, with the removal of 84% for COD, 99.43% for color, and 49.63% for UV300. These results were obtained under optimal conditions of 150 A m−2 current density and an initial pH of 8.79 for 480 minutes. In addition, positive results in the kinetic study also gave this study an appeal. It was seen that ozone-assisted electrooxidation is an effective method for the pharmaceutical wastewater treatment. © 2023, The Authors. All rights reserved.
