Research on third-harmonic injection based on nonlinear active disturbance rejection
Authors: Wu Haozhe , Guo Qingbo 
Published: September 2024

Abstract
With the rapid development of power electronic technology and the permanent magnet industry, Permanent Magnet Synchronous Motor (PMSM) is widely used in high-tech industries such as aerospace and transportation with excellent performance. However, PMSM is a time-varying system with multiple variables and strong coupling, making its control strategy rather complex. It is becoming increasingly important to improve the control strategy. Addressing the issues of easy saturation, poor robustness in PI controllers, and the inconvenience of injecting third-harmonic from the outside into the three-phase three-leg topology to enhance torque density, which leads to insufficient control precision in the PMSM servo system, a nonlinear active disturbance rejection controller (NLADRC) is proposed as the control strategy for the third-harmonic injection-based field-oriented control (FOC). Compared to the PMSM servo system without the injection of third-harmonic, the proposed system exhibits better disturbance rejection capability and higher torque density. Through simulations of the PMSM servo system with the injection of third-harmonic, the proposed control strategy is verified to have good response speed and control performance.

Abstract
The Dynamic Voltage Restorer (DVR) can swiftly and precisely synchronize with the grid’s phase and accurately determine the reference voltage of the DVR in the presence of three-phase unbalanced voltage sag, harmonic distortion, and DC offset in the grid. A stationary reference frame moving average filter phase-locked loop (αβMAF-PLL) can be utilized to efficiently and precisely synchronize the reference voltage of the DVR under less-than-ideal grid conditions. Simulation models of the dynamic voltage restorer under different power network scenarios are created in Matlab/Simulink, with the simulation results confirming the speed and effectiveness of the DVR based on αβMAF-PLL.

Published: September 2024

Abstract
In recent years, heat exchangers have been widely applied in the chemical, petroleum, and power industries, and pipe-type heat exchangers have the advantages of good heat transfer, strong structure, and flexible operation. The side reinforcement of pipe-type heat exchangers is usually achieved using asymmetric pipes, but the existing asymmetric pipes often need help with easy corrosion and difficult processing. To address this issue, this paper proposes a new reed pipe structure based on the reed pipe structure. Focusing on the structural variables of reed pipes and the influence of Reynolds number on the reed pipe flow heat transfer, the empirical correlation formula between each structural variable and Nu and f was fitted using multi-element non-linear regression. The results showed that in terms of heat transfer performance: node number>pharyngeal diameter>pharyngeal length; considering actual production manufacturing, the comprehensive heat transfer performance of the reed pipe has a pharyngeal diameter of 1.3 mm, a pharyngeal length of 3.0 mm, and a node number of 10 is the best.
Research on flow induced vibration characteristics of heat transfer tube plugs in nuclear power plant steam generators

Published: September 2024

Abstract
When the defect of the heat transfer tubes in the steam generator of a pressurized water reactor (PWR) nuclear power plant meets the damage repair standard, plugging must be implemented to prevent the leakage of radioactive coolant materials, but plugging will inevitably affect the flow field state of the original equipment. In order to evaluate the safety of the heat transfer tube plug, this paper takes the heat pipe plugging as the research object, carries out the fluid-solid coupling numerical simulation of the steam generator heat transfer tube plugging based on ANSYS Workbench platform, and analyzes the action law of the fluid at the feedwater end of the bottom of the steam generator on the solid-liquid contact surface in the area. The research shows that the pressure around the plug near the edge of the feedwater end is easy to cause uneven pressure distribution on the pipe-fluid contact surface, thus causing flow-induced vibration of the plug. At the same time, the pressure at the inflow of the pipe is greater due to the scouring of the fluid, which is more likely to cause vibration. In addition, under the action of alternating inflow, the stress value and pressure energy borne by the bottom end of the plug are larger, while the displacement at the top end is larger, and the local stress at the inflow of the plug is the largest. Attention should be paid to the reinforcement of the plug at the inflow, increasing the stiffness of the bottom of the plug, and improving its natural frequency, to prevent it from failing due to resonance.

Published: September 2024

Abstract
Air conditioning is an integral part of a moving train, and when it fails, it will affect passenger satisfaction and electrical safety on the train. By analyzing the principle and failure modes of the air-conditioning system of a certain type of domestic rolling stock, a fuzzy fault tree is constructed in this article, which has the 33 minimum cut sets, for further quantitative analysis. Then, according to the experience of relevant technical personnel and the analysis of air conditioning failure data, the occurrence probabilities of the bottom events are evaluated using the popular triangular fuzzy number. This fault tree can be analyzed quantitatively to find out the probability of the top event and the fuzzy probability importance of the bottom events. Accordingly, we can know the parts of the air-conditioning system of rolling stock that are relatively prone to failure. Through the verification and analysis of real data, it is proved that this is an effective method to locate the weak parts in the air-conditioning system, which can help to identify the possible failure modes and causes, and guide failure diagnosis and prediction of the air-conditioning system, as well as optimize the maintenance program.
Convective heat transfer characteristics from a linearly tapered cylinder at a subcritical Reynolds number
Authors: Zhang Yifan , Lu Luyi 
Published: September 2024

Abstract
This study conducted a numerical investigation of the flow past a linearly tapered cylinder in the subcritical flow regime. This study concentrated on the influence of this geometric perturbation on the flow and heat transfer characteristics by comparing them with those of a uniform circular cylinder. It is revealed that the linearly tapered cylinder effectively reduced the mean drag and fluctuating lift coefficients. The tapered cylinder presented different separation angle locations at different spans, gradually moving backward as the diameter increased. The linearly tapered cylinder provided a higher mean Nu than a uniform cylinder at the same Re of 3000, resulting in an increase of about 25.48% of that for a uniform cylinder. Furthermore, the variation in the Nu over time was correlated with the force coefficients. Different views of the 3D contours depicting the Nu made it evident that the Nu had a maximum at both ends of the cylinder. Characterized by high-speed velocities, the Nusselt number was notably higher in the wake region.
Research on heat dissipation optimization of servers in a computer room under different air supply modes
Authors: Huang Tao , Cao Liangqiang , Wu Yahui , Yan Yan , Wang Wenzhe , Yuan Kai 
Published: September 2024

Abstract
The computational fluid dynamics method is used to study the internal heat dissipation of the original computer room, analyze the reasons for unreasonable temperature distribution, and optimization is adopted. According to the optimized computer room, the flow field and temperature field of two air supply modes are studied, and the results under different inlet air temperatures and flow rates are compared. The results show that the local temperature on both sides of the original computer room is too high, which is because the center of the server on both sides is not effectively ventilated and dissipated. The heat dissipation effect is optimized by adding the upper and lower air vents on both sides of the room, respectively. The calculation shows that the optimization effect is obvious. The top-to-bottom air supply mode and bottom-to-top air supply mode can have a good effect on the heat dissipation of the computer room, but the top-to-bottom air supply mode has a better effect on the heat dissipation of the computer room. Considering factors such as energy saving and cooling effect, it is recommended to choose 44000 m3/h of air intake volume under the top-to-bottom air supply mode.

Abstract
Among the myriad challenges facing humanity, air pollution and climate change emerge as the most formidable existential threats to our future. Ironically, both these are direct fallouts of human activities such as indiscriminate consumption of consumer products/services and burning of fossil fuels. Purchase of consumer goods in 2024 is projected to be in excess of $22.6 trillion worldwide. How these consumers buy, use or dispose consumer goods will profoundly impact all life on the planet. Therefore, it is an imperative to embed sustainability in every Rupee of consumer spending. Hence a robust digital solution, CarbonShunya, has been developed with the purpose to empower a billion consumers to make sustainable purchase and lifestyle choices. CarbonShunya is India’s 1st solution that can measure and mitigate the Greenhouse Gas (GHG) footprint of consumer transactions in real-time. It provides consumers with actionable insights at the point-of-purchase and post-purchase to shape a shift in consumer beliefs, attitudes and behavior. This paper presents the methodology, assumptions and processes which have been adopted to develop the CarbonShunya life-cycle assessment framework and solution in Indian context. It also presents a case study, using the CarbonShunya framework, to measure and mitigate GHG impacts of monthly consumer expenditure on several categories of products/services across various states of India, based on a primary survey of over 174 000 households. The results from the case-study provide actionable insights and conclusions for policymakers and practitioners. CarbonShunya has cross-cutting applications across sectors so as to enable consuming economies to embrace conserving behaviors.

Authors: Altork Yousef , Salem Duaa 
Published: September 2024

Abstract
Adsorption chillers are environmentally friendly cooling systems that use non-hazardous refrigerants, such as CFCs or HCFCs, and are efficient and adaptable for various applications, particularly in utilizing waste heat or low-grade heat sources. The economic viability of a solar water-lithium bromide absorption system in large commercial university building with higher electricity rates in Jordan’s central province was assessed using the Payback Period (PBP) methodology. The system’s PBP was found to be 9.65 years, affirming its economic feasibility. To enhance economic viability, adjustments to the Coefficient of Performance (COP) were explored. Technical evaluations incorporating actual thermodynamic data revealed a COP of 0.785, an improvement from the assumed 0.70. Strategies such as lowering the condenser’s working temperature or increasing the evaporator’s operating temperature positively impacted the system’s performance. Notably, at a condenser temperature of 47.5°C, the COP reached 0.77 with a cooling capacity of 21.48 kW, while at an evaporator temperature of 15°C, the COP and cooling capacity were 0.78 and 21.36, respectively. The study demonstrated that increasing the generator temperature led to a rise in COP, with the highest values of 0.785 and 22.68 kW achieved at 95.0°C. Furthermore, a techno-economic analysis revealed a reduced payback period of 8.66 years, emphasizing the influence of increased COP on the absorption air conditioning system’s economic performance.
Effect of co-doping of CeO2 and Sc2O3 on mechanical properties and CMAS corrosion resistance of YSZ ceramics
Authors: Yuan Pei-Lin 
Published: September 2024

Abstract
Given the escalating demand for advanced materials capable of withstanding extreme temperatures in the aerospace and automotive industries, the development of enhanced thermal barrier coatings is critical. This study introduces a novel thermal barrier coating material synthesized via the co-doping of yttria-stabilized zirconia (YSZ) ceramics with ceria (CeO2) and scandia (Sc2O3). The aim is to enhance mechanical properties and resistance to calcium-magnesium-alumino-silicate (CMAS) corrosion, both crucial for high-temperature applications in aerospace and automotive industries. Through a comprehensive experimental approach involving solid-phase sintering, microhardness, fracture toughness, and nanoindentation tests, the research evaluates the effects of co-doping on the ceramics’ performance. Results demonstrate that CeO2 and Sc2O3 co-doping remarkably improves the corrosion resistance of CMAS and mechanical properties of YSZ, suggesting potential for next-generation thermal barrier coatings in high-temperature environments.
‘Start with the cage’: coercive control and the Roman husband
Authors: Cowan Eleanor 
Published: September 2024

ABSTRACT
This chapter investigates domestic violence in the ancient world by making use of the expanded understanding of the abusive relationship between perpetrator and victim offered by the concept of coercive control. Coercive control describes a pattern of behaviour which may include acts of physical violence, but also non-physical emotional, psychological and financial abuse. I offer four case-studies, each of which takes as its starting point a behaviour associated with coercive control: (1) patriarchal entitlement; (2) patterns of abuse; (3) intimate partner homicide; and (4) non-physical abuse. A broader definition of domestic violence allows us better to understand the abuse (physical and non-physical) experienced by victims in the ancient world and encourages greater sensitivity to the experience of modern victim-survivors of domestic abuse and the ways in which these modern readers (including our students) may interpret ancient evidence.

Published: September 2024

Abstract
Recurrent pregnancy loss represents a common disorder that affects up to 2% of the women aiming at childbirth with long-term consequences on family and society. Factors contributing to it in more than half of the cases are still unknown. Comparative proteomic analysis can provide new insights into the biological pathways underlining the pathogenesis of recurrent pregnancy loss. Until now, chorionic villi, decidua, placenta, endometrium, and maternal blood from women with recurrent pregnancy loss have been analyzed by comparative proteomics studies. In this review, we aimed to provide a critical evaluation of the published comparative studies of recurrent pregnancy loss on human samples, gathered by systematic literature search using PubMed and Google Scholar databases. We provide a detailed overview of the analyzed materials, proteomics platforms, proposed candidate biomarkers and altered pathways and processes linked with recurrent pregnancy loss. The top, most identified and validated biomarker candidates from all studies are discussed, followed by bioinformatics analysis of the available high-throughput data and presentation of common altered processes and pathways in recurrent pregnancy loss. Finally, future directions aimed at developing new and efficient therapeutic strategies are discussed as well.

Abstract

Aims
The study aimed to synthesize evidence of daily physical activity (PA) following Behavior-change technique (BCT)-based interventions compared to any control in individuals with peripheral arterial disease/intermittent claudication (PAD/IC); and examine the relationship between BCTs and daily PA.

Methods and results
Systematic search of 11 databases from inception to 30/11/2022 was conducted, plus weekly email alerts of new literature until 31/8/2023. Studies comparing BCT-based interventions with any control were included. Primary analysis involved a pairwise random-effects meta-analysis. Risk of bias was assessed using the Cochrane-RoB-2 and ROBINS-I tools. Certainty of evidence was evaluated with the GRADE system. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline was followed. Outcome measures were short-term (&lt;6 months) change in daily PA, and maintenance of the daily PA (6 months or longer) reported as standardized mean differences (SMDs) with 95% confidence intervals (95%CIs). Forty-one studies (4339 patients; 26 RCTs/3357 patients; 15 non-RCTs/982 patients; study mean age 60.3 to 73.8, 29.5% female) were included. Eleven RCTs (15 comparisons, 952 participants) suggested that BCT-based interventions increased daily PA in the short term compared to non-SET [increase of 0.20 SMD (95%CI: 0.07 to 0.33), ∼473 steps/day] with high certainty. Evidence of maintenance of daily PA (≥6 months) is unclear [increase of 0.12 SMD (95%CI: −0.04 to 0.29); ∼288 steps/day; 6RCTs, 8 comparisons, 899 participants], with moderate certainty. For daily PA, compared to SET it was inconclusive both for &lt; 6months change [−0.13 SMD, 95%CI: −0.43 to 0.16); 3RCTs, 269 participants; low certainty] and ≥6months [−0.04 SMD, 95%CI: −0.55 to 0.47); 1 RCT, 89 participants; very low certainty]. It was unclear whether the number of BCTs or any BCT domain was independently related to an increase in PA.

Conclusion
BCT-based interventions improve short-term daily PA in people with PAD/IC compared to non-SET controls. Evidence for maintenance of the improved PA at 6 months or longer and comparison with SET is uncertain. BCT-based interventions are effective choices for enhancing daily PA in PAD/IC.
Assembly and annotation of a chromosome-level reference genome for the endangered Colorado pikeminnow (Ptychocheilus lucius)
Authors: Mussmann Steven M 
Published: September 2024

Abstract
Advancements in genome sequencing technology have brought unprecedented accessibility of high-throughput sequencing to species of conservation interest. The potential knowledge gained from application of these techniques is maximized by availability of high-quality, annotated reference genomes for endangered species. However, these vital resources are often lacking for endangered minnows of North America (Cypriniformes: Leuciscidae). One such endangered species, Colorado pikeminnow (Ptychocheilus lucius), is the largest North American minnow and the top-level native aquatic predator in the Colorado River Basin of the southwestern United States and northwestern Mexico. Over the past century, Colorado pikeminnow has suffered habitat loss and population declines due to anthropogenic habitat modifications and invasive species introductions. The lack of genetic resources for Colorado pikeminnow has hindered conservation genomic study of this unique organism. This study seeks to remedy this issue by presenting a high-quality reference genome for Colorado pikeminnow developed from Pacific Biosciences HiFi sequencing and Hi-C scaffolding. The final assembly was a 1.1 Gb genome comprised of 305 contigs including 25 chromosome-sized scaffolds. Measures of quality, contiguity, and completeness met or exceeded those observed for Danio rerio (Danionidae) and 2 other Colorado River Basin leuciscids (Meda fulgida and Tiaroga cobitis). Comparative genomic analyses identified enrichment of gene families for growth, development, immune activity, and gene transcription; all of which are important for a large-bodied piscivorous fish living in a dynamic environment. This reference genome will provide a basis for important conservation genomic study of Colorado pikeminnow and help efforts to better understand the evolution of desert fishes.

Abstract
Garlic is a widely utilized condiment and health product. However, garlic bulbs are prone to quality deterioration resulting in decrease of economic value during postharvest. In this study, the storability of 501 garlic accessions worldwide was evaluated based on the examination of decay index (DI), decay rate, sprouting rate, and bud-to-clove ratio in two consecutive years. The DI was employed as a primary index for evaluating the storability of garlic. Among these garlic, 43 accessions exhibited strong storability with DI of 0%–5%. Phenotypic and cytological observations revealed that strong storability accessions displayed delayed sprouting and decay, a slow rate of nutrient transfer to vascular bundles. Through genome-wide association study (GWAS), 234 single-nucleotide polymorphism loci (SNPs) were associated with the storability, which were located in or near 401 genes, which were annotated the functions of resistance, storage substances transport, etc. A total of 44 genes were screened using selective sweep analysis. Transcriptomic analysis was performed at four periods after storage in the 8N035 accession with strong storability and 8N258 accession with weak storability. Compared with 8N035, the upregulated genes in the 8N258 were enriched in photosynthesis and stress response, whereas the downregulated genes were enriched in response of biotic and abiotic stress and defense response. A co-expression network and GWAS identified three hub genes as key regulatory genes. Conjoint analysis of GWAS, selective sweep, and transcriptomic analysis identified 21 important candidate genes. These findings provided excellent resources with storability and vital candidate genes regulating storability for biological breeding of garlic.
