This paper considers the parameter identification of neuro-fuzzy based Hammerstein output error auto-regressive (OEAR) systems by combining multiple signal source separation principle and auxiliary model identification idea. The unmeasurable internal variable is replaced by the correlation function of input and output data, then correlation analysis method is adopted to identify the parameters of linear

In the processing and manufacturing industries, there has been a large push to produce higher quality products and ensure maximum efficiency of processes, which requires approaches to effectively detect and resolve disturbances to ensure optimal operations. While many types of disturbances can be compensated by a control system, it cannot handle some large process disruptions. As such, it is important

In modern plants with high levels of automation, acquiring an adequate mental model of the process has become a challenge for operators. Studies indicate that sub-optimal decisions occur when there is a mismatch between the demands of the process and the human's capability. This mismatch leads to high cognitive workload in human operators, often a precursor for poor performance. Recently, researchers

In large-scale regional evacuation, public pre-evacuation time estimation is an important link of evacuation analysis and emergency management. This paper redefines the concept of “pre-evacuation time” based on the characteristics of unconventional emergencies. A new prediction model of traffic loading rate for large-scale evacuations based on a real case survey was proposed. The model takes into account

The incidence of large-scale fires continues to rise, and the effects of radiation from these fires contributes to their continued spread. Water sprays have been widely used as an effective method to contain thermal radiation from fires. Results from previous studies on the sizes of water droplets in the spray barrier have limitations due to the significant computational time or complex analytical

Green synthesis provides new avenues of nanoparticle synthesis using plants. In the present study, we attempted to synthesise ZnO nanoparticles via precipitation using different ratios of ZnO solution to leaf extract of Cymbopogon citratus (3:1, 5:1, and 9:1). The modified ZnO was characterised using Fourier transform infrared spectroscopy, transmission electron microscopy, and X-ray diffraction. The

Bioleaching ability of two acidophiles, viz. Acidithiobacillus ferrooxidans, a gammaproteobacteria, and Acidiphilium acidophilum, an alphaproteobacteria in pure and mixed strains was comparatively evaluated for the recovery of metals from waste printed circuit boards (WPCBs) of computer at pulp density in the range of 7.5-15 g/L. Results indicated a variation in metal leachability, showing improved

In this work, para-amino benzoate ferroxane nanoparticle (PABFNP) was employed as a key functional nanoparticle to improve the polyethersulfone (PES) nanofiltration membrane, and PABFNPs blended with PES (PES/PABFNPs) nanofiltration membranes were thus prepared via phase inversion method. PABFNPs may have good compatibility with PES polymer due to intermolecular attractions including hydrogen bonding

Due to the presence of refractory organic pollutants and toxicity compounds, the choice of the best alternative for the landfill leachate treatment becomes a challenge. In this study the integration of aerobic membrane bioreactor with nanofiltration (MBR-NF) and hybrid Fenton-microfiltration process also with nanofiltration (FMF-NF) were compared for the treatment of landfill leachate. The roles of

Co-pyrolysis of plastic/lignocellulosic biomass mixtures produces an extremely complex assortment of pyrolyzates. In the present work, co-pyrolysis of PVC with cellulose or xylan or milled wood lignin was conducted by employing pyrolysis–two-dimensional gas chromatography–time-of-flight mass spectrometry (Py-GC × GC-TOFMS) with the aim of achieving high throughput and comprehensive analysis of the

The computational cost of using discrete element method (DEM) simulations for particulate processes with fine and cohesive particles is enormously large. To overcome this limitation, various coarse-grain DEM models have been developed which use a smaller number of larger sized particles. Although the computational cost is significantly reduced, the accuracy of the simulations depends on the underlying

In this work, we report a proof-of-concept study on CO2 adsorbents synthesized by a thermally initiated free-radical copolymerization and then coated onto carbon paper and poly tetra fluoroethylene via a spray coating approach. A milli-channel reactor was employed to support the obtained materials for efficient CO2 capture with wet conditions, short cooling and heating cycles (303–348 K). CO2 uptake

The goal of this study was to determine oxidation kinetics for biochar produced from fast pyrolysis of various biomass feedstocks. In particular, the role of inherent ash content on the oxidation rate was evaluated. Thermogravimetric analysis (TGA) and fluidized bed combustion experiments were used to explore oxidation kinetics of six fast pyrolysis produced biochars with diverse ash content. Reaction

Miniaturized solid-state lasers have obtained great development for their outstanding properties. Among the optical gain materials discovered so far, CsPbBr3 perovskite quantum dots (QDs) have been recognized as one of the most promising candidates due to the direct bandgap, narrow emission linewidth and high quantum yield. Herein, we report the fabrication of whispering-gallery-mode (WGM) lasers from

Herein, in order to promote the scaled-up manufacturing of efficient nanostructured electrocatalysts, we pioneer a novel ultrafast wet chemistry engineering to turn bulk Co-Ni foam into S activated hydroxide based nanosheets (CoNi-OH|S), with short period less than six minutes. The uniform nanosheets morphology is in-situ formed through designed nitro-hydrochloric acid enhanced corrosion within 30

Droplet-based microfluidics offers an effective approach for overcoming the drawbacks of high viscosity and costs of ionic liquids (ILs) in practical applications. However, studies on the hydrodynamic behavior of the formation of IL-based Janus microdroplets which can facilitate the multifunctional applications of ILs through unique structures, are still limited due to their complex interfacial properties

NaxV2O5∙yH2O have been considered to be very promising electrode materials in the energy storage field by virtue of their V4+/V5+ mixed valences and co-intercalated Na+/H2O. However, the as-reported NaxV2O5∙yH2O usually present the low content of Na+ and the anisotropy of Li+ diffusion in the plane direction. Herein, we successfully synthesize a tetragonal NaV2O5·H2O nanosheets co-intercalated by high

The frequent detection of chloramphenicol (CAP) in wastewater and surface water gives rise to concerns on its fatal myelosuppression and aplastic anemia. Recently, the combination of ozone and peroxymonosulfate (O3/PMS) has received wide attention in removing pollutants due to the multiple oxidants (i.e., O3, hydroxyl radicals (•OH) and sulfate radicals (SO4•−)) existed therein. This study showed that

Operation of supercapacitors at sub-zero temperatures with reasonable performance is of great importance for their outdoor applications. Herein, the sub-zero performance of supercapacitors assembled from nitrogen-doped porous carbon electrodes with interconnected tubular structure using ionic liquid as electrolyte is reported. The carbon-based electrode materials are synthesized by pyrolysis of po

Silicon is extensively researched as an substitute for carbon as the anode material in Li-ion batteries. However, the cycle life of Si is very short because of its high volume expansion. Herein, we propose SiNx deposited by radio frequency reactive sputtering at room temperature as an anode material. Sputtering presents the advantage of being easily applicable to fabricate all-solid-state thin film
