Concurrent generation and amplification of longitudinal and bending waves using defective phononic crystals

引用

Applied Mathematics and Mechanics(English Edition) 2025年第2期46卷 269-288页

作者： S.H.jo Department of Mechanical Robotics and Energy Engineering Dongguk University

Defective phononic crystals (PnCs) have enabled spatial localization and quantitative amplification of elastic wave energy. Most previous research has focused on applications such as narrow-bandpass filters, ultrasonic sensors, and piezoelectric energy harvesters, typically operating under the assumption of an external elastic wave incidence. Recently, a novel approach that uses defective PnCs as ultrasonic actuators to generate amplified waves has emerged. However, the existing studies are limited to the generation of either longitudinal or bending waves, with no research addressing the concurrent generation of both. Hence, this paper proposes a straightforward methodology for the concurrent generation and amplification of both wave types utilizing defect modes at independent defect-band frequencies. Bimorph piezoelectric elements are attached to the defect, with each element connected to independent external voltage sources. By precisely adjusting the magnitude and temporal phase differences between the voltage sources, concurrently amplified wave generation is achieved. The paper highlights the advantages of the proposed analytical model. This model is both computationally timeefficient and accurate, in comparison with the COMSOL simulation results. For instance,in case studies, the analytical model reduces the computational time from one hour to mere seconds, while maintaining acceptable error rates of 1%in peak frequencies. This concurrent wave-generation methodology opens new avenues for applications in rotating machinery fault diagnosis, structural health monitoring, and medical imaging.

Occasional Tillage in a Field Established under Conservation Agriculture for Tomato Cropping

The Conservation Agriculture (CA) is a current concept drives to save natural resources for agricultural production based on the minimum soil disturbance or no-tillage, crop rotation and permanent maintenance of straw on soil surface. The increasing in soil density is a problem to achieve great copping yield under CA, so occasional one-time tillage is considered as an alternative to continuous no-tillage. In this way, this experiment was carried out to compare occasional tillage and no-tillage interacting with cover crops in a field established under conservation agriculture. Thus, the experimental treatments were set up by two tillage methods, conventional tillage and no-tillage and two cover crops, white lupin and millet setting in a randomized blocks with split plot design with four replications. The traits evaluated in the research were soil fertility, soil resistance to penetration, soil moisture and tomato agronomic performance. No-tillage was more efficient to preserve soil moisture;however soil fertility, soil resistance to penetration and tomato yield were favored by conventional tillage. Regarding to cover crops white lupin increased the soil K concentration and enhanced the tomato growth. Although occasional tillage had better performance to the soil fertility and tomato yield, we highlighted that CA is the better way to increase soil health and soil and water conservation along the time leading to so desired regenerative agriculture.

We study embeddings between generalised Triebel–Lizorkin–Morrey spacesε_(ϕ,p,q)^(s)(R^(d))and within the scales of further generalised Morrey smoothness spaces like N_(ϕ,p,q)^(s)(R^(d)),B_(p,q)^(s,ϕ)(R^(d))and F_(p,q)^(s,ϕ)(R^(d)).The latter have been investigated in a recent paper by the first two authors(2023),while the embeddings of the scale N_(ϕ,p,q)^(s)(R^(d))were mainly obtained in a paper of the first and last two authors(2022).Now we concentrate on the characterisation of the spacesε_(ϕ,p,q)^(s)(R^(d)).Our approach requires a wavelet characterisation of those spaces which we establish for the system of Daubechies’*** we prove necessary and sufficient conditions for the embeddingε_(ϕ1,p1,q1)^(s1)(R^(d))→ε_(2ϕ2,p2,q2)^(s)(R^(d)).We can also provide some almost final answer to the question whenε_(ϕ,p,q)^(s)(R^(d))is embedded into C(R^(d)),complementing our recent findings in case of N_(ϕ,p,q)^(s)(R^(d)).

Lignocellulosic biomass is one of the viable solutions to alleviate the global warming. However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the economic and environmental feasibilities. To cope with this issue, we proposed an integrated process of co-producing 1,6-hexanediol(1,6-HDO) with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To compare the impacts of lignin upgrading and feedstock, Strategy B, which co-produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating costs and indirect carbon emissions due to energy consumption, saving 87% and 83% of the heat and cooling requirements, respectively, in Strategy A. The market competitiveness of Strategy A was evaluated by determining the minimum selling price through techno-economic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments(LCAs).Strategy A was found to be the most favorable both economically(USRDSCHARDOLLAR3,402/ton) and environmentally(-26.9 kg CO_(2)eq.). This indicates that lignin valorization is not only economically but also environmentally preferred. Finally, changes in economic and environmental feasibilities depending on economic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.
