Rayleigh-type waves on a coated elastic half-space with a clamped surface
Authors: Kaplunov J. , Prikazchikov D. , Sultanova L. 
Published: September 2019

Elastodynamics of a half-space coated by a thin soft layer with a clamped upper face is considered. The focus is on the analysis of localized waves that do not exist on a clamped homogeneous half-space. Non-traditional effective boundary conditions along the substrate surface incorporating the effect of the coating are derived using a long-wave high-frequency procedure. The derived conditions are implemented within the framework of the earlier developed specialized formulation for surface waves, resulting in a perturbation of the shortened equation of surface motion in the form of an integral or pseudo-differential operator. Non-uniform asymptotic formula for the speeds of the sought for Rayleigh-type waves, failing near zero frequency and the thickness resonances of a layer with both clamped faces, follow from the aforementioned perturbed equation. Asymptotic results are compared with the numerical solutions of the full dispersion relation for a clamped coated half-space. A similarity with Love-type waves proves to be useful for interpreting numerical data.

(Bi)-orthogonality relation for eigenfunctions of self-adjoint operators
Authors: Ledet L. S. , Sorokin S. V. 
Published: September 2019

The bi-orthogonality relation for eigenfunctions of self-adjoint operators is derived. Its composition is explained in view of the structure of a characteristic equation and of the energy flow components. Application of the bi-orthogonality relation for solving forcing problems is generalized and the connection between the bi-orthogonality relation and the virtual wave method is highlighted. Technicalities are illustrated in a non-trivial example of propagation of free/forced cylindrical waves in a thin elastic plate under heavy fluid loading.This article is part of the theme issue ‘Modelling of dynamic phenomena and localization in structured media (part 1)’.

Published: September 2019

In this paper, we study the spectral properties of a finite system of flexural elements connected by gyroscopic spinners. We determine how the eigenfrequencies and eigenmodes of the system depend on the gyricity of the spinners. In addition, we present a transient numerical simulation that shows how a gyroscopic spinner attached to the end of a hinged beam can be used as a ‘stabilizer’, reducing the displacements of the beam. We also discuss the dispersive properties of an infinite periodic system of beams with gyroscopic spinners at the junctions. In particular, we investigate how the band-gaps of the structure can be tuned by varying the gyricity of the spinners.

A new insight into corrosion inhibition process of mild steel in sulfuric acid medium: a combined experimental and theoretical study
Authors: Boutouil Aziz , Laamari My Rachid , Elazhary Ilham , Anane Hafid , Ben Tama Abdeslem , Stiriba Salah-Eddine 
Published: September 2019

PurposeThis study aims to investigate the inhibition effect of a newly synthesized1,2,3-triazole containing a carbohydrate and imidazole substituents, namely,1-((1-((2,2,7,7-tetramethyltetrahydro-5H-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-5-yl)methyl)-1H-1,2,3-triazol-4-yl)methyl)-1H-benzo[d]imidazole(TTB) on the corrosion of mild steel in aerated 1 M H2SO4.Design/methodology/approachThe authors have used weight loss measurement, potentiodynamic polarization, electrochemical impedance spectroscopy, FT-IR studies, scanning electron microscopy analysis and energy dispersive X-ray (EDX) spectroscopy techniques.FindingsIt is found that, in the working range of 298-328 K, the inhibition efficiency of TTB increases with increasing concentration to attain the highest value (92 per cent) at 2.5 × 10−3M. Both chemisorption and physisorption of TTB take place on the mild steel, resulting in the formation of an inhibiting film. Computational methods point to the imidazole and phenyl ring as the main structural parts responsible of adsorption by electron-donating to the steel surface, while the triazol ring is responsible for the electron accepting. Such strong donating–accepting interactions lead to higher inhibition efficiency of TTB in the aqueous working system.Originality/valueThis work is original with the aim of finding new acid corrosion inhibitors.

Authors: Włodarska Katarzyna , Pawlak-Lemańska Katarzyna , Sikorska Ewa 
Published: September 2019

PurposeThe purpose of this paper is to analyse physicochemical and sensory profiles of apple juices using multivariate methods and to predict the essential sensory properties by means of instrumental measurements.Design/methodology/approachThe studied set included apple juices reconstituted from concentrate (clear and cloudy) and direct (pasteurised and freshly squeezed, not pasteurised). The physicochemical (colour, turbidity, total soluble solids, sucrose, D-glucose, D-fructose content, pH, total acidity, total phenolic, total flavonoid content and antioxidant capacity) and sensory profiles of juices were analysed by principal component analysis and partial least squares (PLS) regression.FindingsAn exploratory study of physicochemical and sensory profiles revealed dimensions differentiating apple juices. The first dimension was related to their physical properties (clarity, sediment and colour coordinates L*, C*, h°), whereas the second dimension referred to their flavour, being positively correlated with sourness and astringency, and negatively with sweetness. The PLS regression analysis revealed the quantitative relationship between sweet and sour flavours and the instrumental measurements. The physicochemical parameters of apple juices contributing positively or negatively to the key sensory attributes were determined based on the regression coefficients.Originality/valueThis study presents a possibility to predict the key sensory attributes of apple juice on the basis of selected physicochemical parameters. This approach could be a supporting tool for sensory analysis that could allow the quality characterisation on a large sample set and hence shorten the time necessary for routine quality control, product design and development.

Archives in the stacks: documentary editions in collections
Authors: Riter Robert B. 
Published: September 2019

Purpose
This paper aims to investigate the role of documentary editions in supporting the development of historical collections in libraries, their function as evidential and informational objects and considerations for their evaluation in collection development. Framed as objects possessing bibliographic and archival characteristics, attention is given to the evaluative challenges these objects present during collection development.

Design/methodology/approach
This paper provides an archival and bibliographic analysis of documentary editions through examining and discussing their archival and bibliographic elements. Consideration is given to how these elements are expressed as information and evidence, how they operate as scholarly and archive-like objects and how they acquire value as collected objects. This approach clarifies the informational and evidential characteristics of these works, offering a framework for their evaluation in libraries.

Findings
Documentary editions possess archival and bibliographic characteristics, requiring that evaluators critique the scholarly value and archival integrity of their content. This has implications for the curation of archival objects in library collections, where library and archival expertise can support a more nuanced assessment of these works.

Originality/value
The blurred documentary character of these works has been identified by scholars (Cox, 1991). This paper presents evaluative considerations. Here, these characteristics are clarified, and an approach for evaluating these works is offered.

Authors: Reid David McHardy , Chi Guotai , Zhao Zhi Chong , Alon Ilan 
Published: September 2019

PurposePerformed over a five-year time horizon, this paper aims to analyze the progression rates of technological innovation across 15 sub-provincial Chinese cities. The authors quantify and rate innovation performance, then rank the cities based on a purpose-built index designed to gauge the rate of technological progress.Design/methodology/approachUsing the inferior constraint method, and a variety of national sources of data, the authors construct an innovation index based in part on new product sales revenue, proportion of college students, research and development expenditure of industrial enterprises in relation to gross industrial output value, contract deals in technical markets per capita, hazard-free treatment rate of waste, enterprises with technical development agencies accounts for industrial enterprises, number of high-tech enterprises and invention patent ownership per million population.FindingsThe findings provide a methodology for indexing cities, with 15 Chinese provincial cities as examples. Among the top five cities with the highest technological innovation index were Shenzhen, Nanjing, Guangzhou, Hangzhou and Wuhan. In the bottom were Shenyang, Changchun, Dalian, Xi’an and Harbin.Research limitations/implicationsThis study applied a new model of innovation at the city level for China. Application to other industries (real estate, manufacturing, etc.) and countries will extend boundaries of this model and show its wider applicability.Practical implicationsCompanies can use this research and methodology when seeking new investments in high tech and innovative products. Locations offering more hospitable environments should be prioritizedceteris paribus.Originality/valueOne weakness of much of the international business and competitiveness literature is that it often views the country as the primary unit of analysis. In this way, nuanced views of the institutional environments within countries are often overlooked. This paper proposes a measure of regional rates of innovativeness across China.

An integrated model of destination sustainable competitiveness
Authors: Nadalipour Zahra , Imani Khoshkhoo Mohammad Hossein , Eftekhari Abdolreza Roknoddin 
Published: September 2019

PurposeThis study aims at developing a framework to investigate and analyze sustainable competitiveness in tourism destinations.Design/methodology/approachThis study has a qualitative approach, and it has been conducted by use of a comprehensive literature review. First, the key concepts of the study such as destination competitiveness, sustainable development, stakeholders’ attitude and performance and tourist loyalty were identified. Then, an integrative review was conducted on literature regarding the mentioned keywords. More related resources were selected and critically reviewed to explore gaps. For this purpose, a search was conducted at databases such as Emerald, Elsevier and ScienceDirect.FindingsAn appropriate framework for tourism sustainable development and, in particular, for its sustainable competitiveness, requires considering economic, sociocultural and ecological dimensions on the one hand, and considering all stakeholders participating in tourism process on the other hand.Research limitations/implicationsThe model suggested in this study can be applied by managers and policymakers in various destinations to investigate true competitiveness situation of their tourist destinations. It also can be theoretically a start point to raise further issues and studies on destination competitiveness by adopting a new sustainability approach.Originality/valueFrom reviewing previous studies, it is clear that most models developed on destination competitiveness only consider creation of competitiveness and destination’s characteristics. In addition, a sustainability approach has rarely been considered in these studies. A model or a framework specially designed for evaluating and investigating sustainability of destination competitiveness has not been developed yet. In this sense, the proposed framework in this study is a new one. What differentiates this model with previous ones is the sustainability approach to the competitiveness and taking all stakeholders of the competition process into account.
A domain knowledge incorporated text mining approach for capturing user needs on BIM applications
Authors: Zhou Shenghua , Ng S. Thomas , Lee Sang Hoon , Xu Frank J. , Yang Yifan 
Published: September 2019

Purpose
In the architecture, engineering and construction (AEC) industry, technology developers have difficulties in fully understanding user needs due to the high domain knowledge threshold and the lack of effective and efficient methods to minimise information asymmetry between technology developers and AEC users. The paper aims to discuss this issue.

Design/methodology/approach
A synthetic approach combining domain knowledge and text mining techniques is proposed to help capture user needs, which is demonstrated using building information modelling (BIM) apps as a case. The synthetic approach includes the: collection and cleansing of BIM apps’ attribute data and users’ comments; incorporation of domain knowledge into the collected comments; performance of a sentiment analysis to distinguish positive and negative comments; exploration of the relationships between user sentiments and BIM apps’ attributes to unveil user preferences; and establishment of a topic model to identify problems frequently raised by users.

Findings
The results show that those BIM app categories with high user interest but low sentiments or supplies, such as “reality capture”, “interoperability” and “structural simulation and analysis”, should deserve greater efforts and attention from developers. BIM apps with continual updates and of small size are more preferred by users. Problems related to the “support for new Revit”, “import & export” and “external linkage” are most frequently complained by users.

Originality/value
The main contributions of this work include: the innovative application of text mining techniques to identify user needs to drive BIM apps development; and the development of a synthetic approach to orchestrating domain knowledge, text mining techniques (i.e. sentiment analysis and topic modelling) and statistical methods in order to help extract user needs for promoting the success of emerging technologies in the AEC industry.
