In response to the challenges inherent in Baijiu classification, characterized by ambiguity and limited methodologies, this study introduces a novel framework for comprehensive Baijiu brewing process management. By integrating mathematical models and machine learning algorithms, our aim is to standardize and enhance the accuracy of the Baijiu brewing process. Through a meticulous analysis of 13 input features using the MRMR algorithm, we identified key variables that significantly influence base wine grades. Subsequently, we compared the efficacy of support vector machine (SVM) algorithms under three kernel functions for base wine grading classification. Additionally, we developed an enhanced particle swarm-support vector machine (IPSO-SVM) algorithm, which incorporates nonlinearly decreasing inertia weights to enhance global and local search capabilities. Evaluation metrics, including accuracy and F1-SCORE, were employed to assess the model's performance. Our experimental results demonstrate that IPSO-SVM significantly improves convergence speed and accuracy, achieving a classification accuracy of 98.31% on the test set with an F1-SCORE of 98.18%. Furthermore, experimental tests conducted at a prominent strong-flavored wine enterprise in China validated the model's effectiveness, revealing no significant difference in grading quality between model and manual Baijiu classification, with a mean error below 1%. This study presents a pioneering approach to digitize and standardize Baijiu classification processes, laying theoretical foundations for the development of intelligent Baijiu classification systems. © 2024 John Wiley & Sons Ltd.

Fourier-transform infrared（FT-IR） spectroscopic experiments were carried out during phosphate adsorption on highly crystalline gibbsite, poorly crystalline 2-line-ferrihydrite and amorphous iron–aluminum–hydroxide mixtures in the molar ratio 1：0, 10：1, 5：1, 1：1, 1：5, 1：10 and 0：1. The OH stretching vibrational bands were utilized to analyze changes in structural and surface OH groups during adsorption, because the position of characteristic P／O vibrational bands can shift depending on reaction conditions, pH or adsorbed phosphate *** and desorption kinetics were studied at pH6 and different initial phosphate concentrations to achieve varying phosphate coverage on the mineral surfaces. For gibbsite the formation of AlHPO4 and Al2HPO4 can be assumed, while for ferrihydrite, a FeHPO4 or Fe2PO4 complex and the precipitation of FePO4 with longer equilibration time were ***2HPO4 or a Fe2PO4 surface complex was deduced for Fe-hydroxides, an AlH2PO4 surface complex was identified for Al-hydroxide, and both displayed either hydrogen bonds to neighboring hydroxyl groups or hydrogen bonds to outer-sphere complexes. Fe：Al-hydroxide mixtures with high Al ratios showed a low phosphate desorption rate, while ferrihydrite and the Fe：Al-hydroxide mixtures with high Fe ratios had almost negligible desorption rates. It was concluded that within the weakly associated amorphous FeO（OH） materials, FePO4 precipitated, which was bound by outer-sphere hydrogen bonds. With high Al ratios, desorption increased, which indicated weaker phosphate binding of both inner-sphere and outer-sphere complexes and hence, either no or minor quantities of precipitate. Ferrihydrite showed a more rigid structure and a lower extent of precipitation compared to amorphous Fe-hydroxide.

Undertaking varying working conditions is common for a machine tool. One single reliability model for determining a single effect is not suitable for the reliability evaluation of machine tools due to the multi-effect of working conditions on the reliability of machine tools. This paper proposes a generalized model using hazard functions and Weibull distribution to assess the reliability of machine tools under different effects of working conditions. This model considers three effects, including the proportional hazard, time, and additive hazard effects. The distribution of time effect is discussed. Furthermore, a secure parameter estimation method is presented to calculate the proposed reliability model. A case study based on field data is presented. The proposed model is compared with classical reliability models. The result shows that the proposed model has better goodness of fit for the realistic cumulative distribution of machine tools.

For vehicle drivetrain system parts such as gears, case hardening heat treatment with carburizing is well used to improve wear and rolling contact fatigue properties. However, distortion would occur during heat treatment processes, which may be a problem in improving the precision of the gear shape. Predicting distortion behavior accurately by heat treatment simulation method could help us achieve a good heat treatment quality and parts' shape accuracy. In this article, heat treatment simulation that is the predicting method from cooling situation to heat treatment distortion and computer fluid dynamics that is the predicting method from flow condition to cooling phenomena are combined. This combined method can estimate heat treatment quality on mass production treatment, especially in stable flow condition or some cooling conditions. However, especially for a continuously variable transmission pulley quenched in high-speed flow oil condition, the accuracy of heat treatment simulation is lower than other conditions. We estimated this to be the effect of turbulence generated in the flow. © 2018 by ASTM International.

Within past 20 years, high surface qualities of cold strip were demanded by automotive industry and electrical engineering. Main purposes of cold rolling processed are to provide high quality surface and generate appropriate roughness for different customs. Emulsion is a common coolant used in cold rolling processes, Properties of base oil in emulsion, concentration, roughness of work roll, rolling speed and reduction are important parameters, which dominate the surface qualities of cold rolled strip. Hence, a powerful cold rolling model which can describe complicate tribological behavior in roll bite is required. In this article, a cold rolling model which integrates roll deformation and mixed lubrication in inlet zone and biting area was developed. The thickness of oil film, fraction of contact area and coefficient of friction in roll bite are calculated. © 2015 Trans Tech Publications, Switzerland.

Characterisation of submicron size entrainment in the aqueous product stream of a 40 mm diameter centrifugal extractor for 30% tbp/nitric acid biphasic system

Annular centrifugal extractor is a favoured solvent extraction contactor where process flowsheet requires a low hold-up, lower residence times and compact layout. However during operation of annular centrifugal extractor, a small entrainment, generally of the order of few hundred ppm, is always observed. To characterise this small entrainment, hydrodynamic experiments in a no-mass transfer mode were conducted on a 40 mm centrifugal extractor with 30%TBP/dodecane and acidified water. The aqueous product stream was analysed by dynamic light scattering based methods and drop size distribution was experimentally measured. The maximum entrained micro-drop size was typically below 1 μm in most of the cases and in the rest it was well below 10 ?m. Thus the original assertion, that small entrainment occurred due to micro-sized drops, was proved right. However due to complex relations of peak locations and relative peak intensities to the physical and operating properties of solvent extraction system, mathematical modelling or correlation of experimental results was not feasible.

Determination of distribution coefficient: A critical Review

引用

International Journal of Environment and Waste Management 2014年第1期14卷 27-64页

Geomaterials (soils and rocks) exhibit peculiar physical, chemical, mineralogical and biological properties, which influence their interaction with the contaminant(s) to a great extent. This interaction can be quantified by employing a parameter 'Distribution coefficient', kd, which plays an important role for determining sorption and desorption characteristics of the contaminant when it interacts with geomaterial(s). Apart from the soil specific properties, kd depends upon the pH of the pore solution, ambient temperature, type and concentration of competitive ions, the presence of microorganisms, etc. Usually, batch, column and lysimetric tests are employed for determining kd. However, it has been observed that kd varies in a wide range and the methodologies adopted for its determination have their limitations and shortcomings. As such, these methodologies are being critically evaluated by researchers so that they may be modified or replaced by new ones, which are easy to adopt and yield reliable results quickly. With this in view, efforts have been made in this paper to highlight the importance and role of parameters that influence determination of kd. Further, details of the studies related to determination of kd as reported by earlier researchers and a commentary on the guidelines for determining it are also presented in this paper.
