Loop Design

This paper deals with in loop design of coupling elements of the wireless charging systems (WChS). The in-loop design is created as a script/User Interface (UI) in MATLAB environment, which is based on finite element models of WChS. Main aim of developed tool is to easily identify the optimal geometrical parameters of the coupling coils. The optimization of the coil’s geometrical and electrical parameters is specified by an algorithm, which is based on definition for transfer of required amount of power and on geometrical restrictions of the target application. The second part of the proposed script/UI is used for user guided design of the electromagnetic shielding. It enables to optimize the shielding parameters in order to reach the limits defined by international standards for safety levels with respect to human exposure. Proposed design methodology together with user interface have been verified though experimental validation. For this purpose, construction of WChS was realized based on the results from in loop design process. Comparisons have been made according to the evaluation of simulation model´s accuracy, that is, the values of self-inductances, mutual inductances, coupling coefficient and gain characteristics have been evaluated (simulations vs. experiments). At the end of the paper the evaluation of the shielding performance was realized, while once more the comparison between simulation and experiments have been made. Received results are showing less than 2% of the relative error. Using presented methodology, the fast optimization actions can be done during design and modelling of WChS.

Purpose This paper aims to analyse the implications of globalisation and the adoption of international standards (International Financial Reporting Standards [IFRS]) for accounting information quality. Design/methodology/approach This paper uses a sample of 329 banks across 29 countries leading up to and beyond the implementation of IFRS to test for related hypotheses. Findings First, banks’ financial statements are prepared on the basis of international standards as national economies are integrated when social norms are diffused. Building on these results, the second test suggests that the relatively high-quality earnings among banks in Africa during the period is attributable to the adoption of and interaction of IFRS with globalisation and the strategy of banks to diversify within and across interest and non-interest income. Originality/value The authors investigate how globalisation and the adoption of IFRS affect accounting information quality.

New Framework

Purpose – The purpose of this paper is to investigate the feasibility of creating a declarative user interface language suitable for rapid prototyping of mobile and Web apps. Moreover, this paper presents a new framework for creating responsive user interfaces using JavaScript. Design/methodology/approach – Very little existing research has been done in JavaScript-specific declarative user interface (UI) languages for mobile Web apps. This paper introduces a new framework, along with several case studies that create modern responsive designs programmatically. Findings – The fully implemented prototype verifies the feasibility of a JavaScript-based declarative user interface library. This paper demonstrates that existing solutions are unwieldy and cumbersome to dynamically create and adjust nodes within a visual syntax of program code. Originality/value – This paper presents the Guix.js platform, a declarative UI library for rapid development of Web-based mobile interfaces in JavaScript.

The Impact

Purpose Library impact and how to evaluate it has been debated for a number of years. While the activity – the busy-ness – of the library is now routinely measured and described, the difference the library makes is less tangible and harder to measure. Libraries in all sectors and worldwide are grappling with this issue, and the purpose of this paper is to summarise international standards available to support them. Design/methodology/approach The first international standard concerning library impact, ISO 16439 Information and documentation – methods and procedures for assessing the impact of libraries, was published in 2014 after several years in development. Findings The standard describes a range of methods for assessing library impact which have been used across the world in a variety of libraries in all sectors. Originality/value This paper summarises the key methods described in the standard, and gives references for further reading.

Study Results

Purpose The purpose of this paper is to investigate the trained and untrained users’ mental models compatibility with search module icons in three Iranian digital library applications, namely, Nika, Azarakhsh, and Simorgh. Design/methodology/approach The population of this survey consisted of two groups including trained and untrained users. The trained user group consisted of 174 samples, all of which were included in the study due to scarcity of the samples. The untrained user group consisted of 8,210 samples, from which 267 cases were selected through stratified sampling. Findings Results showed that the trained users’ mental models were more compatible with the search module icons than those of the untrained users. The comparison of three software applications showed that the mental models of trained and untrained users had the highest compatibility with the search icons of Azarakhsh and the lowest compatibility with those of Nika. Concerning the untrained users’ status in terms of their fields of study, results showed that users majoring technical and engineering field and those in agriculture had, respectively, the highest and lowest mental models compatibility with the icons embedded in the user interface of the studied applications. Originality/value Since the mental models may be incomplete or inaccurate, the study of the trained and untrained users’ mental models compatibility with the search module icons of user interface embedded in various library applications may help in assessing the software’ status and the designers’ level of success in conveying the content. This also may assist information literacy specialists to estimate the required amount of training for trained and untrained users.

This work will demonstrate the development and experimental validation of the stochastic models to predict the composite material’s mechanical and electromagnetic response as a function of the constituent reinforcing materials. First, stochastic micromechanics models will be developed for the case of multiple disparate supporting materials. These micromechanics models will then be validated against traditional finite element models and experimental results over the feasible parameter space. The developed models will then be utilized to define the optimal geometry of the composite flywheel including constraints such as displacement, stress, flux, magnetic field density, and manufacturability.

Practical Implications

Purpose The strategic importance of the purchasing function increases, as its task become more dynamic in various interfaces with different suppliers. Changes in these customer–supplier interfaces pose specific challenges. The purpose of this study is to investigate how the purchasing function handles the interplay of interface changes. Design/methodology/approach This study applies a qualitative single case study design. Data are collected through observations and interviews conducted before, during and after a concrete change of interface taking place between a buying firm and its suppliers and customers. Findings Three main findings are identified to redefine the tasks of the purchasing function. The first concerns the new ways of defining the purchasing tasks. The main issue is to balance tasks with the simultaneous changes influencing other interfaces and relationships. The second is the division and alignment of tasks in intra- and inter-organizational networks with regards to who decides and coordinates what. Third, the inter-connected performance relates to how other actors perform their tasks. For the purchasing function, managing supplier interfaces influences and is influenced by how the firm simultaneously manages its user interface. Practical implications For management, a new way to evaluate the performance of the purchasing function is needed by including relationship management and interactive capabilities. Originality/value This study contributes with new insights into how managing the dynamics of changing interfaces requires interactively defined purchasing tasks, division and alignment of tasks and inter-connected performance vis-à-vis others in the wider network setting.
