A practically oriented, efficient alternative to the Monte Carlo method for measurement uncertainty estimation
Authors: Degenhardt Johannes , Tutsch Rainer , Hu Xiukun , Dai Gaoliang 
Published: February 2025

Abstract
This paper addresses the problem of uncertainty estimation for measurements made with computationally expensive numerical models, which are increasingly applied today. Typically, the Monte Carlo method (MCM) is used for uncertainty propagation in these cases. However, due to its stochastic nature, the MCM is inefficient, requiring a large number of model evaluations and thus resulting in long computation times. In this paper, an efficient alternative to the MCM is introduced. By using systematic samples of the influence quantities which are individually propagated through the measurement model, the overall number of required model evaluations can by drastically reduced. Additionally, the new method offers the possibility to simplify the measurement model for further reduced computational effort. The distributions of the propagated samples are reconstructed using a method specifically designed for systematic samples and combined to the uncertainty distribution of the measurand using convolution. The new method does not only offer increased computational efficiency but also a high information yield, as it estimates the uncertainty distribution of the measurand and the uncertainty contribution of individual influence quantities.

Abstract
Red mud is a highly alkaline industrial solid waste generated by the alumina industry. Its stacking and disposal not only occupy land resources, but also cause environmental pollution. It is of great significance to separate and purify target compounds from complex mixtures of red mud based on their resource utilization properties. Ferrous oxalate and ferric hydroxide were prepared by oriented conversion based on redox reaction and chemical precipitation in this research. The products prepared were characterized by XRD, SEM and IR under different conditions (iron powder, ascorbic acid and photocatalysis). The results show that the two-stage acid leaching process can improve the leaching rate of iron from red mud significantly, and the experimental of oriented conversion of ferrous oxalate and ferric hydroxide from red mud with reproducibility. The sample prepared with ascorbic acid as reducing agent has the best effect. The development of this experiment provides a new idea for the directional classification and purification of ferrous oxalate and iron hydroxide from red mud.

Abstract
Rubber asphalt has excellent durability and can maintain excellent performance under harsh service conditions. In order to further promote the application of rubber asphalt, the dynamic rheological shear test was used to test the complex shear modulus G *, rutting factor G */sin δ, fatigue dissipation factor G * sin δ of rubber asphalt under different test temperatures and loading frequencies. The conclusions are as follows: (1) For the dynamic rheological properties of rubber asphalt, the content of rubber powder is an important factor. When the rubber powder content is 30%, the rheological properties of rubber asphalt are optimal. (2) For the rutting factor and fatigue dissipation factor of rubber asphalt, temperature and frequency are the primary influencing factors. The rutting factor and fatigue dissipation factor of rubber asphalt samples in each group decrease with increasing temperature and increases with increasing frequency. (3) Among the three types of rubber powder-mixed rubber asphalt, the 30% rubber asphalt has higher high-temperature performance and fatigue performance, which can meet the performance requirements of the pavement surface layer.

Abstract
Failure of accessories of high-pressure natural gas compressors is harmful. In this paper, taking the fracture accident of the cylinder support bolt of a natural gas compressor in an oil field as an example, the causes of the fracture failure of the bolt are studied, as the chemical composition, hardness, metallographic structure, and inclusions of the bolt are tested and analyzed, the macro morphology of the fracture is observed and analyzed, the micromorphology of the fracture is observed by scanning electron microscope and energy spectrum analysis, and the installation structure and operating conditions of the bolt are studied. The results show that the fatigue fracture of the bolt at the stress concentration at the root of the thread under the vibration alternating load of the compressor is the reason for the fracture failure of the bolt. It is suggested to strengthen compressor vibration monitoring and take appropriate vibration reduction measures to reduce the impact of compressor vibration.

Authors: Shi Peilei , Xu Guanjun 
Published: February 2025

Abstract
The wheel-edge drive mechanism is a forward-looking technology of new energy electric vehicles, but the wheel-edge drive mechanism increases the unsprung mass due to the addition of the hub drive motor and the planetary wheel reducer, which deteriorates vehicle smoothness and grounding. In light of the problems above, the worm gear two-stage reducer wheel edge drive mechanism is adopted. The 1/4 vehicle vibration model was established in MATLAB/Simulink and simulated for improving the ride comfort of the vehicle and the grounding of the wheel, based on the considerations of the influence of damping coefficient, suspension stiffness, and unsprung mass on smoothness and grounding. The stiffness and damping coefficient of the suspension was optimized in consideration of the calculation results and relevant evaluation indicators. The results indicate that the optimization of suspension system parameters effectively reduces the impact of vertical vibration on vehicle ride comfort.

Published: February 2025

Abstract
Black sludge is commonly found in the acid tanks of cold rolling pickling lines and in the pipelines of acid regeneration units, impacting system efficiency and causing negative effects on equipment and the environment. To address this issue, a method combining black sludge composition analysis and Chemical Oxygen Demand (COD) measurement of rinse water was proposed to study its origin and formation mechanisms. The results showed that the black sludge mainly contains carbon, chlorine, oxygen, and small amounts of iron, with significant organic matter loss between 300-400°C, indicating a high content of alkanes and cycloalkanes. The COD value of rinse water is higher when fresh acid is used, and alkanes and cycloalkanes are the main contributors to the formation of black sludge and the increase in COD values. Strengthening the management of fresh acid can help reduce sludge formation.

Abstract
Melting and decontamination of decommissioned waste metals from nuclear power plants requires cutting and disintegration first, dry cutting process can effectively avoid the generation of waste liquid and aerosol in large amounts and a complex treatment process. Low-level radioactive 316 L austenitic stainless steel decommissioned from nuclear power plants has a large amount and poor cutting performance, decontamination enterprises need to balance and improve productivity, cost, and waste knife disposal in the sawing disintegration process. Taking AlCrN coating circular saw knife and TiN thin coating circular saw knife as the research object, the durability test of dry sawing 316L stainless steel pipe with two factors and two levels was carried out. The tool wear mechanism and the applicability of the maximum durability of AlCrN coated circular saw knife are analyzed, the empirical formula of tool durability in the form of a selective subset equation is established, a list algorithm of maximum productivity durability and minimum cost durability based on TableCurve 3D interpolation function is proposed. The results show that under the cutting conditions of low rotational speed and large feed rate, the two kinds of coated knives have the highest productivity durability and the lowest cost durability, at this time, the AlCrN coated tool has slightly better durability and slightly worse economy. The empirical formula of tool durability in the form of a selective subset equation has the advantages of fewer sample points, diverse expressions, and high model accuracy. The list algorithm overcomes the limitations of the traditional algorithm that the feed per tooth needs to be selected first, the relationship between cutting speed and durability must be expressed as a power function, the calculation results need to be rounded, and the equation is likely to have no solution. The calculation results are in line with engineering practice.

Published: February 2025

Abstract
A dump truck with a maximum designed total mass of 25000 kg was selected to measure the real driving emission characteristics of pollutants and carbon dioxide (CO2) under different altitudes of 0 meters, 800 meters and 1600 meters, with the same simulated road, driver and vehicle model but different vehicle loading of 0% and 40% by using the engine-in-the-loop (EIL) methodology. The results indicate that the EIL methodology can qualitatively and quantitatively analyze the impact of altitude on real driving emissions. The emissions of carbon monoxide (CO) and total hydrocarbons (THC) show a trend of first decreasing and then increasing with increasing altitude, while the emissions of particulate number (PN) show a trend of first sharply increasing and then slightly decreasing with increasing altitude. The variation pattern of nitrogen oxide (NOx) emissions with altitude is not significant. Under different altitude conditions, the specific emissions of CO2 and THC decrease with increasing vehicle loading, while the specific emissions of PN and CO increase with increasing vehicle loading. However, the variation pattern of NOx emissions with vehicle loading is not obvious. In addition to being strongly correlated with exhaust temperature, the peak value of NOx emissions is highly correlated with road slope and vehicle acceleration. Cold start increases the specific emissions of CO2 and pollutants, especially for PN and CO.

Liquid Chromatograph-High Resolution Mass Spectrometry Analysis of the Fluorinated Proteins in Antarctic (Euphausia Superba) Krill Muscle
Authors: Jiang Zhongquan , Shen Xiaosheng 
Published: February 2025

Abstract
This study aims to analyze the fluorinated proteins in Antarctic krill (Euphausia superba) muscle using liquid chromatography-high resolution mass spectrometry (LC-HRMS) to explore the binding form, composition, binding mechanism, and molecular weight range of fluorine with proteins, providing a scientific foundation for improving the defluorination efficiency of Antarctic krill. Polypeptides from Antarctic krill muscle were enzymatically extracted using trypsin, fractionated by ultrafiltration and gel filtration chromatography (GFC), and purified by C18 reversed-phase high-performance liquid chromatography (RP-HPLC). Fluorine content and molecular weights of the polypeptide fractions were determined by ion chromatography (IC) and HPLC-Q/Orbitrap MS. Among the three separated polypeptide fractions AKP-I, AKP-II, and AKP-III, AKP-II had the highest fluorine content of 1219.52 µg/g, accounting for 63% of the total fluorine, followed by AKP-I with 495.04 µg/g, accounting for 26%, and AKP-III with the lowest fluorine content of 209.44 µg/g, accounting for 11%. The molecular weight of fluorophosphorus peptides in AKP-II was measured to be approximately 2000 Da. The results indicate that fluorine in Antarctic krill muscle is accumulated through ion exchange adsorption between fluorapatite (FHAP) and the amino acid side chains, maintaining a stable fluorine content. This study provides new insights into the binding mechanism of fluorine in Antarctic krill muscle and offers a scientific basis for the development of targeted defluorination methods.

Authors: Tian Hongyun , Luo Pan , Shuai Jing , Xie Linna , Xi Tingting , Huang Yongbing 
Published: February 2025

Abstract
This study aimed to utilize chelating agents for the remediation of heavy metal (HM)-contaminated river sediments. The removal efficiency and mechanisms of the green chelating agents glutamic acid (GLDA) and methyl glycine diacetic acid (MGDA) were analyzed under various conditions. The research findings indicate that the removal efficiency for Cd is GLDA> EDTA=MGDA, the removal efficiency for Cu is MGDA=GLDA> EDTA, and for Ni, the removal efficiency is MGDA> GLDA> EDTA. The green chelating agents GLDA and MGDA can remove HMs from river sediments efficiently without harming the environment, serving as alternatives to EDTA. Chelating agents achieve this effect by altering the speciation of HMs in river sediments, with system pH being the primary influencing factor. The supernatant treated with Na2S contained HMs at levels compliant with national discharge standards, making it suitable for direct discharge.
