Abstract:

The higher-order structure and attribute hierarchical structure are two popular approaches to defining the latent attribute space in cognitive diagnosis models. However, to our knowledge, it is still impossible to integrate them to accommodate the higher-order latent trait and hierarchical attributes simultaneously. To address this issue, this article proposed a sequential higher-order latent structural model (LSM) by incorporating various hierarchical structures into a higher-order latent structure. The feasibility of the proposed higher-order LSM was examined using simulated data. Results indicated that, in conjunction with the deterministic-inputs, noisy “and” gate model, the sequential higher-order LSM produced considerable improvement in person classification accuracy compared with the conventional higher-order LSM, when a certain attribute hierarchy existed. An empirical example was presented as well to illustrate the application of the proposed LSM.

Abstract:

In this paper, a structural model of a geomedium (a soil) is proposed in the form of a simple cubic lattice of spherical particles (blocks) possessing three translational and three rotational degrees of freedom. The force and couple interactions between the particles are modeled by elastic springs of five types. A long-wavelength continuum mathematical model of the soil has been elaborated by the method of structural modeling. An analytical relationship between its macroconstants and microstructure parameters has been found. It is shown that the obtained model differs from the model of the reduced Cosserat medium, which is often employed to describe granular media. In the low-frequency approximation, it can be reduced to the equations of the higher-order gradient theory of elasticity, which are similar to the Cosserat continuum equations with constrained rotation of particles. These equations contain both terms with mixed derivatives with respect to time and coordinate that take into account the inertia of particles rotation in the medium and lead to the wave dispersion, and terms proportional to the spatial derivatives of the fourth order, which describe the contribution of stresses caused by bending of the medium to the potential energy. In the framework of the higher-order gradient model, expressions for the classical and couple stresses in the considered geomedium are found. Boundary conditions are set that consist in the absence of normal and shear stresses on the upper platform of a half-space medium. A condition for the microstructure parameters has been revealed, under which the couple stresses can be neglected. The proposed here higher-order gradient model with given boundary conditions can be used to investigate the propagation and interaction of elastic waves in a semi-infinite geomedium, which are generated by the high-speed movement of trains, as well as to identify and study potentially dangerous effects caused by such movement.

Abstract:

The objective is to improve the linear constraints for optimizing the helical structure (radius and pitch of the conductor winding) of nonuniform helical antennas for desired characteristics such as signal gain or bandwidth. Presented below are equations that allow various higher-order structural constraints to be used in such optimizations. Their efficacy is demonstrated by analogy, using data for a fully optimized Yagi-Uda antenna, before being applied to data available for helical designs. The comparisons confirm the general validity of the higher-order equations to model some of the most advanced antennas produced to date. A simple calculus-of-variations test confirms that an improved optimization is possible by adding curvature terms to previously published linear constraints.

Abstract:

The traditional methods of evaluating entrepreneurial behavior carry a degree of uncertainty and subjectivity with several uncontrollable independent variables. Faced with this fragility, the modeling of structural equations can be a tool that contributes to the understanding of this behavior. In order to contribute in this direction, this study aimed to develop a structural model for measuring entrepreneurial behavior based on behavioral characteristics and entrepreneurial intent. The research is applied, quantitative, descriptive and exploratory. In order to satisfy the problem raised, data collection instruments already validated were used. The sample consisted of 2,519 respondents. The internal consistency of the scales proved to be reliable for the measurement and evaluation of the constructs. In the descriptive analysis it was identified that the achievement dimension obtained higher score, moreover, more than 90% of the participants present entrepreneurial behavioral characteristics and intend to undertake. Then, behavioral characteristics and entrepreneurial intention were related by developing a structural model for entrepreneurial behavior. It was concluded that the model is apt to measure entrepreneurial behavior. The research was limited to the construction of a model of measurement of entrepreneurial behavior from the instruments answered by undergraduate students from a public higher education institution. Future studies can expand the constructs addressed in the structural model, as well as be replicated in other institutions of higher or basic education in order to compare, deepen and new findings, in addition to considering a longitudinal follow-up. The originality of the study lies in the development of a structural model for measuring entrepreneurial behavior.

Abstract:

The finite element method (FEM) is widely used in many engineering applications. The popularity of FEM led to the development of several variants of formulations, and hexahedral meshes surged as one of the most computationally effective. After briefly reviewing the reasons and advantages behind the formulation of increasing order elements, including the serendipity variants and the associated reduced integration schemes, a systematic comparison of the most common hexahedral formulations is presented. A numerical benchmark was used to assess convergency rates and computational efficiencies when solving the eigenvalue problem for linear dynamic analysis. The obtained results confirmed the superior performances of the higher-order brick element formulations. In terms of computational efficiency, defined as the ratio between achievable accuracy and computational execution time, quadratic or cubic formulations exhibited the best results for the stages of FE model assembly and solution computation, respectively.

Abstract:

Customer engagement has emerged as a vital component in social media marketing strategies, prompting considerable interest from both marketers and academics. This study investigates customer engagement (CE) in a framework that includes three antecedents and a main outcome (loyalty). Based on the survey method, we test a proposed model on social media users. The data analysis focuses on exploratory and confirmatory factor analyses, as well as structural equation modeling to test the hypotheses, and a multi-group analysis. The results validate CE as a multidimensional construct and support all hypotheses of the conceptual model. As key contributions, the study reveals involvement as the strongest antecedent of customer engagement and emphasizes the importance of CE in predicting and fostering customer loyalty. This paper adds to the existing body of knowledge on customer–brand relationships by establishing the main drivers for customer engagement in digital settings, with valuable theoretical and practical perspectives. Finally, our findings provide managerial recommendations on the development of social media marketing strategies conveyed to enhance customer engagement.

Full text

Abstract:

A standard stress path triaxial test system was applied to carry out conventional triaxial shearing tests for gravelly sands under confining pressures ranging from 50 kPa to 400 kPa at the initial relative densities of 0.15, 0.35, 0.55, and 0.75, respectively. The test results show that all the samples of gravelly sand present strain hardening and shear contraction during the process of shearing test. Additionally, gravelly sands are significantly affected by the initial relative density. The hardening degree of gravelly sand samples rises in line with increasing initial relative densities during shearing tests. When initial relative densities Dr are at 0.15 and 0.35, the volume shrinkage of samples decreases with the increasing confining pressures. Instead, when initial relative densities Dr are at 0.55 and 0.75, the volume shrinkage of samples increases with the growth of confining pressures. To describe these triaxial shearing mechanical properties of gravelly sands, a higher-order dilatancy equation was proposed based on the concept of a super yield surface. A constitutive model which can describe the mechanical properties of gravelly sand was established when the associated flow laws were applied to compare with the results of the triaxial shearing test under the consolidated drained condition. The comparison results showed that the proposed model can reflect the strain hardening and shear contraction characteristics of gravelly sands from low to high confining pressures under different initial relative densities.

Abstract:

The Drinking Motives Questionnaire, previously postulated and documented to exhibit a measurement structure of four correlated factors (social, enhancement, conformity, and coping), is a widely administered assessment of reasons for consuming alcohol. In the current study ( N = 552), confirmatory factor analyses tested the plausibility of several theoretically relevant factor structures. Fit indices corroborated the original four-factor model, and also supported a higher-order factor model involving a superordinate motives factor that explicated four subordinate factors. A bifactor model that permitted items to double load on valence type (positive or negative reinforcement) and source type (external or internal) generated mixed results, suggesting that this 2 × 2 motivation paradigm was not entirely tenable. Optimal fit was obtained for a bifactor model depicting a general factor and four specific factors of motives. Latent factors derived from this structure exhibited criterion validity in predicting frequency and quantity of alcohol usage in a structural equation model. Findings are interpreted in the context of theoretical implications of the instrument, alternative factor structures of drinking motives, and assessment applications.

Abstract:

Unravelling how the human brain structure gives rise to function is a central question in neuroscience and remains partially answered. Recent studies show that the graph Laplacian of the human brain’s structural connectivity (SC) plays a dominant role in shaping the pattern of resting-state functional connectivity (FC). The modeling of FC using the graph Laplacian of the brain’s SC is limited, owing to the sparseness of the Laplacian matrix. It is unable to model the negative functional correlations. We extended the graph Laplacian to the hypergraph p-Laplacian in order to describe better the nonlinear and high-order relations between SC and FC. First we estimated those possible links showing negative correlations between the brain areas shared across subjects by statistical analysis. Then we presented a hypergraph p-Laplacian model by embedding the two matrices referring to the sign of the correlations between the brain areas relying on the brain structural connectome. We tested the model on two experimental connectome datasets and evaluated the predicted FC by estimating its Pearson correlation with the empirical FC matrices. The results showed that the proposed diffusion model based on hypergraph p-Laplacian can predict functional correlations more accurately than the models using graph Laplacian as well as hypergraph Laplacian.

Abstract:

A new micromechanics model is presented which is capable of accurately estimating both the effective elastic constants of a periodic multiphase composite and the local stress and strain fields in the individual phases. The model is presently limited to materials characterized by constituent phases that are continuous in one direction, but arbitrarily distributed within the repeating unit cell which characterizes the material’s periodic microstructure. The model’s analytical framework is based on the homogenization technique for periodic media, but the method of solution for the local displacement and stress fields borrows concepts previously employed by the authors in constructing the higher-order theory for functionally graded materials, in contrast with the standard finite element solution method typically used in conjunction with the homogenization technique. The present approach produces a closed-form macroscopic constitutive equation for a periodic multiphase material valid for both uniaxial and multiaxial loading which, in turn, can be incorporated into a structural analysis computer code. The model’s predictive accuracy is demonstrated by comparison with reported results of detailed finite element analyses of periodic composites as well as with the classical elasticity solution for an inclusion in an infinite matrix.

Abstract:

This study examines the relationships among learning orientation, firm innovativeness and financial performance in the context of the Norwegian wood industry. A questionnaire-based survey was sent to the CEOs of firms in the wood industry in Norway (241 usable replies, response rate of 49 percent). Learning orientation and firm innovativeness were conceptualised and analysed as latent second-order constructs by using structural equation modelling. The findings show that learning orientation has a positive effect on firm innovativeness in the traditional manufacturing industry. In addition, learning orientation was found to positively affect financial performance via the full mediating effect of firm innovativeness. Furthermore, firm innovativeness was also found to have an independent positive effect on financial performance. No direct effect of learning orientation on financial performance was found. According to the data, firm age also does not appear to affect the relationship between learning orientation and firm innovativeness.

Abstract:

One of the modern directions for the further development of the applied geometry scientific school of the Igor Sikorsky Kyiv Polytechnic Institute is the structural-parametric shaping of various technical objects. Currently, the general theoretical foundations of this methodology and specialized means of its practical implementation are being developed. The results obtained in the design, manufacture and operation of specific industrial products largely depend on their efficiency. The created mathematical models serve as the basis for software modules, which become components of the applied computer information systems. In these conditions, the issues of developing the necessary methodological support are also important. From the side of the theory of structural-parametric shaping, requirements are imposed on new geometric means in accordance with the principles of universality and unification, variability, openness and development, a system approach, etc. As can be seen from the title of the publication, in our case we are talking about second-order surfaces, which, due to their useful properties, are quite common in many technical objects. Note that the plane is considered a simplified version of these figures. The indicated universality and unification consist in solving a wide range of problems using the same type of methods, techniques, algorithms, etc. Variability is the need to implement for the geometric model of its flexible and productive use, the openness and the development – of easy updating, expansion and improvement its components. The systems approach requires considering the created mean not only as interconnected elements, but also as a part of systems of a higher hierarchical level. The submitted second-order surface model satisfies the rules described above. Its main peculiarity lies in the combination of the vector definition of these items with the structural-parametric methodology. The developed techniques of shaping are suitable for wide practical use during the automated design of various technical objects, the processes of their production and operation.

Abstract:

Purpose The purpose of this study is to validate the higher education service quality (HESQUAL) scale using a confirmatory approach and test an improved structural model that predicts student loyalty from image, perceived value, satisfaction and service quality. In addition to validating the HESQUAL scale using a confirmatory approach, two other main limitations in the extant literature are addressed. Design/methodology/approach The model is tested using data collected from 501 students enrolled in different higher education institutions in Mauritius. A two-stage approach to structural equation modeling is used whereby the measurement model is first tested using confirmatory factor analysis and followed by the assessment of the structural model. Findings Importantly, results indicate that student satisfaction is influenced by technical service quality, image and perceived value, but not by functional service quality. Both dimensions of service quality however are significant predictors of image and perceived value. The study uses a comprehensive measure of service quality and demonstrates that it is worthwhile to consider functional service quality as higher-order model and clearly distinguish between functional and technical quality, as both the technical and functional aspects play an important role in shaping students’ perceptions and behaviors. Originality/value First, in the existing literature, service quality has not been considered as a second-order factor model in structural models of student satisfaction and loyalty, thus lacking either precision or parsimony. Second, the transformative quality aspect of higher education has been largely neglected in previous research testing such predictive models. The model delineates service quality into the functional and transformative (technical) aspects and treats functional service quality as a second-order factor comprising nine sub-dimensions.

Abstract:

Structural equations are extensively used in studies dealing with abstract variables. The authors can choose between first and higher-order constructs but some researchers omit to pursue a rigorous method. Therefore, it is important to know: when is the higher-order construct preferred to the first-order one? In this study, the authors have illustrated this procedure for perceived value and trust. They collected data with students, inviting them to navigate in a website and to fill-in a questionnaire. Results show the superiority of the second-order reflective model for perceived value and trust. The decision is taken relying on theoretical and empirical justifications. The authors have also proven the predictive ability of their variables by confirming their positive relationship with commitment. The latter predicts behavioral intentions. Second-order reflective constructs invite managers to pay attention to all the first-order factors because a negative perception of one of the factors contributes to the deterioration of the second-order construct.

Abstract:

The frequency responses of free vibrated composite sandwich panel structure are investigated numerically by considering the geometrical nonlinearity via generalised Green–Lagrange strain kinematics in the framework of the equivalent single layer theory. The consistency and the accuracy of the current finite element solutions have been checked by solving a wide variety of examples taken as same as the reference. After the model standardisation, it is further extended to show the influence of various geometrical design parameters (side-to-thickness ratio, core-to-face thickness ratio, curvature ratio, lamination scheme and support condition) on the nonlinear frequencies of the sandwich composite flat/curved panel structure evaluated when computed using higher-order kinematic model. Also, the sandwich structural responses obtained using the equivalent higher-order kinematic model not only easy to implement but also the computational cost is low without hampering the accuracy of structural response.

Abstract:

Purpose – Several dimensions of public governance occur while approaching the Shadow Economy (SE) phenomenon. The purpose of this paper is to study the SE by means of the European governance analysis by highlighting the main features of implications of the policy options. A statistical significance on the nexus between public governance and the SE appears with respect to the indicators taken into consideration except for the dimensions related to the tax system, which appear to be moderate in magnitude in terms of their effects. Design/methodology/approach – In order to evaluate data from 32 European Union countries during 2011, a hierarchical component model (HCM) in the context of the structural equation model (SEM) partial least squares (PLS) is utilised. Two different procedures are considered: a two-stage approach (TSA) and the repeated indicators approach (RIA). Findings – The two procedures (RIA and TSA) proposed in the model have about the same impact on the SE. Evidence suggests that the manifest variables joined to the regulatory system, business regulation and wealth level significantly affect the SE. In contrast, different dimensions connected to the tax system need to be considered to avoid that there be no significant effects on the SE from taxes. Research limitations/implications – A critical evaluation of the policy implications of the results are included, by focusing on the effects on the SE. Practical implications – This paper suggests where more emphasis should be placed when referring to the statistical results in dealing with the SE. Originality/value – To the authors’ knowledge, this is the first attempt to explore the SE while using an HCM (also known as higher order model) performed in a SEM-PLS procedure. The model proposed discerns the relevance and the marginal impact of several dimensions of policy interventions.

AbstractThis study examined the factor structure and model specifications of the Interaction Anxiousness Scale (IAS) with confirmatory composite analysis (CCA) using partial least squares-structural equation modeling (PLS-SEM) with a sample of Italian adolescents ($$n = 764$$ n = 764 ). The CCA and PLS-SEM results identified the reflective nature of the IAS sub-scale scores, supporting an alternative measurement model of the IAS scores as a second-order reflective–reflective model.

Abstract:

A novel higher-order coupled finite-boundary element scheme is presented for the computation of the thermoacoustic responses of the layered panel structure under the harmonic excitation. The thermally pre-stressed vibrating composite panel model is derived mathematically using the higher-order shear deformation mid-plane kinematics. The eigen frequencies and the corresponding vibrational mode shapes are computed via the finite element method using Hamilton’s principle. Similarly, the surrounding medium is modeled via Helmholtz wave equations and solved numerically using the boundary element steps for the computation of the acoustic responses. The frequency and sound radiation output are computed numerically by means of an own computer code prepared in MATLAB environment. To avoid excess thermal loading during analysis, the critical buckling temperature of the composite panel structure is obtained and the range of thermal loading is selected accordingly. The model accuracy is demonstrated through the proper comparison studies of different structural responses (critical buckling temperature, natural frequency and radiated sound power level) of the curved composite panel with the available benchmark solutions. The reliability and the usefulness of the proposed novel scheme have been revealed by solving several numerical illustrations for different lamination schemes, panel geometries including the geometrical parameters.

Abstract:

Abstract Ribosomal protein S1 plays important roles in the translation initiation step of many Escherichia coli mRNAs, particularly those with weak Shine-Dalgarno sequences or structured 5′ UTRs, in addition to a variety of cellular processes beyond the ribosome. In all cases, the RNA-binding activity of S1 is a central feature of its function. While sequence determinants of S1 affinity and many elements of the interactions of S1 with simple secondary structures are known, mechanistic details of the protein's interactions with RNAs of more complex secondary and tertiary structure are less understood. Here, we investigate the interaction of S1 with the well-characterized H-type pseudoknot of a class-I translational preQ1 riboswitch as a highly structured RNA model whose conformation and structural dynamics can be tuned by the addition of ligands of varying binding affinity, particularly preQ1, guanine, and 2,6-diaminopurine. Combining biochemical and single molecule fluorescence approaches, we show that S1 preferentially interacts with the less folded form of the pseudoknot and promotes a dynamic, partially unfolded conformation. The ability of S1 to unfold the RNA is inversely correlated with the structural stability of the pseudoknot. These mechanistic insights delineate the scope and limitations of S1-chaperoned unfolding of structured RNAs.

Abstract:

Abstract Human telomeres contain the repeat DNA sequence 5′-d(TTAGGG), with duplex regions that are several kilobases long terminating in a 3′ single-stranded overhang. The structure of the single-stranded overhang is not known with certainty, with disparate models proposed in the literature. We report here the results of an integrated structural biology approach that combines small-angle X-ray scattering, circular dichroism (CD), analytical ultracentrifugation, size-exclusion column chromatography and molecular dynamics simulations that provide the most detailed characterization to date of the structure of the telomeric overhang. We find that the single-stranded sequences 5′-d(TTAGGG)n, with n = 8, 12 and 16, fold into multimeric structures containing the maximal number (2, 3 and 4, respectively) of contiguous G4 units with no long gaps between units. The G4 units are a mixture of hybrid-1 and hybrid-2 conformers. In the multimeric structures, G4 units interact, at least transiently, at the interfaces between units to produce distinctive CD signatures. Global fitting of our hydrodynamic and scattering data to a worm-like chain (WLC) model indicates that these multimeric G4 structures are semi-flexible, with a persistence length of ∼34 Å. Investigations of its flexibility using MD simulations reveal stacking, unstacking, and coiling movements, which yield unique sites for drug targeting.

Abstract:

Objective: To evaluate the structural validity of the Wechsler Intelligence Scale for Children–Fourth Edition (WISC-IV). Method: Confirmatory factor analyses were applied to a sample of 233 students diagnosed with ADHD by school multidisciplinary evaluation teams to evaluate the relative fit of the following competing models: (a) one factor, (b) two oblique verbal and nonverbal factors, (c) three oblique verbal, perceptual, and combined working memory/processing speed factors, (d) four oblique verbal, perceptual, working memory, and processing speed factors, (e) a higher-order model with four first-order factors, and (f) a bifactor model with four domain-specific factors. Results: A higher-order four-factor model fit the data best, which was composed of a general intelligence factor and four domain-specific factors that matched the four factors specified in the WISC-IV technical and interpretive manual. Moreover, the general intelligence factor explained more than two times the total variance contributed by all four domain-specific factors combined. Conclusions: Results substantiate previous research on the WISC-IV, indicating that the general intelligence factor contributes the most reliable information. Consequently, it is recommended that interpretation of the WISC-IV remain at the Full-Scale IQ score level.

Abstract:

The solutions of Riemann problems of a particular higher-order model—the Payne-Whitham (PW) model—are studied using Roe’s flux splitting scheme as presented by Leo and Pretty. Despite numerous works on higher-order models, little is known about Riemann solutions of these models and how relaxation and anticipation affect these solutions. Riemann solutions of the PW model are computed and compared with those of the Lighthill-Whitham-Richards (LWR) model having the same initial (density) data. It was found that faster relaxation forces the PW model to behave much like the LWR model, that strong anticipation has a stabilizing effect on traffic, and that shock waves travel at different speeds in the PW model than they do in the LWR model. These findings provide a basic checklist for experimental validation of PW-like higher models.

Abstract:

Higher-order thinking skills (HOTS) are one of the important components that students must master to be successful in the 21st century. The HOTS of students in several regions in Indonesia is low because HOTS-based learning and the instruments are not appropriate. This study aims to determine the validity and reliability of the HOTS assessment content, empirical, and constructs referring to bloom theory in laboratory work. The development model used is the Plomp development model, which consists of five stages: initial investigation, design, realization/construction, test, evaluation and revision, and implementation. The HOTS assessment was proven relevant by experts and then distributed to 70 Physics Education students. The HOTS assessment was analyzed by rash model theory analysis with the Winstep program to obtain empirical validity. SEM (Structural Equation Model) was used to obtain construct validity. The results showed that the HOTS assessment was valid and reliable. The results show that the assessment has been able to measure every aspect of HOTS well in laboratory work so that it can be used.

Abstract:

The acoustic radiation responses of laminated sandwich baffled flat panels subjected to harmonic loading in an elevated thermal environment are investigated via a novel coupled finite and boundary elements formulation based on the higher-order shear deformation shell theory. The structural stiffness and mass tensors are obtained using competent finite element steps engaging the Hamilton’s principle followed by computation of acoustic responses by resolving the Helmholtz partial differential equation. An in-house MATLAB code is developed based on the present formulation for the computation of all the desired responses. The accuracy and robustness of the present scheme are recognized by the close conformance of the critical buckling temperature, natural frequencies and the sound power level values with the available benchmark solutions alongside the values obtained via a simulation model implemented using commercially available finite element (ANSYS) and boundary element (LMS Virtual.Lab) packages. Subsequently, the present model is employed to solve wide variety of numerical illustrations and the useful inferences related to the influence of elevated temperature, core-to-face thickness ratio, core-to face modular ratio and lay-up scheme on the sound emission characteristics of sandwich composite flat panels are deliberated in detail.

Abstract:

A simple linear-chain model is utilized in calculation of the mechanical and structural properties of metallic glasses. The model calculations of composition-dependent elastic constants show good agreement with the experimental data available for binary metallic glasses. The model is capable of distinguishing different structural characteristics of glassy systems and provides excellent agreement with the radial distribution functions of amorphous cobalt, metal–metalloid, and binary transition metal glasses. The model is not limited to binary systems and can be readily applied to ternary and higher order metallic glasses.

Abstract:

This paper presents the results from a new set of 3-D physical model tests performed in a 6.5 m wide flume at the Centre for Harbour and Coastal Studies in Madrid. These results will contribute to enhance the existing knowledge obtained in previous studies. Among other variables, they cover concrete-cubes armours and the submergence is increased, with a higher model scale. Damage criterions are discussed and proposed for both types of armour. The latter takes into account the different damage growth observed between rock and cubes-armours. Lower thresholds are proposed for cubes in order to increase the safety, though still allowing some movements before considering the damage is reached.

Further, we introduce the unstructured latent structural model and the higher order latent structural model. We also show how to extend these models to consider polytomous attributes, the testlet effect, and longitudinal diagnosis. Finally, we present an empirical example as a tutorial to illustrate how to use JAGS codes in R.

Abstract:

In this paper, a two-dimensional time-domain numerical flume has been established to model and investigate nonlinear interactions between nonlinear surface waves and a submerged inclined thin plate. The model solves the Laplace equation and the fully nonlinear free surface boundary conditions within the framework of potential flow theory based on the high-order boundary element method. The mixed Euler–Lagrangian method is applied to update the water surface at each time step, and the fourth-order Runge–Kutta method for time stepping. A so-called four-point method was employed to separate the second-order harmonic free and bounded wave that has the same wave frequency but different wave celerity in front of and behind the submerged plate. It is found that the amplitude of the second-order harmonic free wave increases with the inclination angle of the submerged plate, and the level/amount of the increase is larger for a larger wave steepness. In addition, the amplitudes of both the second-order reflected and transmitted waves are found to increase with the wave steepness, and their empirical relationships are derived for potential use in practical engineering.
