Abstract

Purpose

The paper aims to elaborate the method and algorithm of analysis of induction motor working in cryogenic temperature.

Design/methodology/approach

This paper presents the design and investigation of performance characteristics of three‐phase high voltage squirrel‐cage submerged motor. The motor is intended to work at cryogenic temperature −161°C in liquefied natural gas (LNG). The time‐stepping finite element method of transients analysis in induction motor working in cryogenic temperature has been presented. The nonlinearity of the magnetic circuit, the movement of the rotor and skewed slots have been taken into account.

Findings

The study finds that presented method and elaborated software are used to determine the steady state and dynamic performance of the high voltage squirrel‐cage submerged motor. The results of simulations and measurements of constructed model motor have been presented.

Research limitations/implications

The problem has been considered as the 2D one. In order to take into account the skewed slots of the rotor the multi‐slice finite element method has been used.

Practical implications

Investigation presented in the paper has been performed in order to study the influence of the temperature on motor characteristics and to verify design calculations. No‐load current, starting torque and short‐circuit current during short‐circuit test, obtained on the basis of measurements and received from calculations, are in good concordance.

Originality/value

The paper proposes a method to determine the steady state and dynamic performance of the high voltage squirrel‐cage submerged motor working in cryogenic temperature.

Abstract

Purpose

The purpose of this paper is to compare torque calculation methods when a non‐conforming movement interface is implemented by means of Lagrange multipliers.

Design/methodology/approach

The following methods are here used for computing the torque in a synchronous machine and in a switched reluctance motor: Arkkio's method (AM), local Jacobian matrix derivative (LJD) method, Maxwell stress tensor method (MST) and co‐energy variation method.

Findings

This paper shows that, the numerical stability produced by Lagrange multipliers yields a stable torque result, even in thin airgap machines if AM, LJD method or MST method are used.

Originality/value

This work presents a comparative study to indicate the performance of the most commonly used torque calculation methods, when a non‐conforming technique is used, considering a small displacement of the rotor, which is necessary for dynamic cases or coupling with circuit.

Abstract

Purpose

University Accountancy faculty need criteria to assist with the selection of textbooks, to ensure that the subject matter is congruent with the level at which students are taught. Readability is one such criterion. The purpose of this study is to assess the readability of two Managerial Accounting and two Financial Management textbooks, using three different readability evaluation methods.

Design/methodology/approach

The sample for the study included 281 Accounting students from an Eastern seaboard university. Each student was requested to complete two passages – one from a Management Accounting textbook and one from a Financial Management textbook. The Gunning Fog Index, Flesch Reading Ease and Cloze Procedure readability evaluation methods were used to measure readability.

Findings

The findings suggest varying levels of readability among the textbooks. Results from the Cloze Procedure reveal that three of the four textbooks were being read at the Frustration Level and the fourth marginally above the Frustration Level. The readability formulae returned varying results demonstrating that some of the textbooks were at a level that the students ought to be able to read.

Research limitations/implications

Only two Managerial Accounting and two Financial Management textbooks of many published were assessed, and only three readability evaluation methods were used.

Social implications

The findings have implications for university faculty, authors, publishers, editors and students.

Originality/value

The readability of Managerial Accounting and Financial Management textbooks used at South African universities, has received scant attention in the literature. The analysis of the readability of the accounting textbooks, presents a synthesis that adds important knowledge in this under‐researched topic.

Abstract

The cloze procedure has been seen by accounting researchers as a useful tool for investigating the communicative effectiveness of accounting narratives. Compared with text‐based readability measures, such as the Flesch test, the cloze procedure has often been viewed as an alternative and superior method of measuring understandability. Provides a critical review of the accounting and educational cloze‐based literature. In particular, questions the validity of the cloze procedure, the cloze procedure’s measurement of understandability, and the correctness of the criterion reference scores traditionally used to interpret cloze scores. Concludes that these legitimate concerns about the cloze procedure must be taken into account when the results of cloze‐based accounting research studies are evaluated. Repeats calls for further research to establish the validity of the cloze procedure in the accounting domain and to support the results of existing studies.

Abstract

A model coupling magnetic and electric equations is developed in this paper. The unknowns in this model are the magnetic vector potential and the mesh currents. The nature of the resulting matrix system does not permit the use of the classical Cholesky algorithm. A new decomposition, based on the Cholesky method, is introduced to solve it. To illustrate the efficiency of the method, an example of an iron core coil is modelled. Both calculation time and memory storage are compared with classical methods.

Abstract

A basic difficulty encountered in applying the finite element method to unbounded wave problems is that the domain in which the field is to be computed is unbounded, while finite element models are of finite size. There are several ways to overcome this difficulty. The widely used method is to truncate the finite element model at a finite position and apply suitable boundary conditions there. The relevant boundary conditions must absorb the outgoing wave and have been called absorbing boundary conditions (ABC's).

Abstract

Academic integrity is of great importance to insure a consistent determination of what constitutes plagiarism across regions of the world. Academic integrity research spans a global scale and regardless of where the researcher is from, they are building on a pool of research findings that have no physical boundaries. Basic agreed upon research standards and fundamentals must be established to ensure the validity and reliability of the body of academic research. Problematic to the situation are differences in cultural definitions of what constitutes plagiarism. Therefore, this study aimed to build the body of knowledge on the current condition of plagiarism levels as well as perform a sample comparison of some patterns in Eastern and Western culture. A document analysis was conducted for two universities, one in the USA and one in Saudi Arabia. In addition, a survey was conducted in an academic context in Saudi Arabia to investigate students’ and faculty’s understanding of what constitutes plagiarism. It was predicted that Saudi Arabia is shifting towards a Westernized definition of plagiarism; results partially supported this hypothesis.

Abstract

Purpose

The purpose of this study is to examine the relationship between the understandability of an accounting textbooks written in English and the language learning motivation of international students. Previous research assumed that native speakers of a language and second-language speakers would understand a given accounting text similarly and little attempt has been made to ascertain any individual differences in users’ capacity to read and understand a foreign language.

Design/methodology/approach

The 107 participants in this study comprised of full-time English as a Second Language postgraduate commerce students studying at a major Australian university. The authors used two-part questionnaire to examine the motivation of participants and the understandability of an accounting textbook using the Cloze test.

Findings

The results suggest that most international students have difficulty in understanding the textbook narratives used in this study. Furthermore, the results show that students’ motivation to learn a foreign language impacts on the understandability of an accounting textbook.

Practical implications

This study will help the educators, textbook publishers and students to understand the needs of ESL students. It is expected to provide guidance for authors and instructors to enhance the effectiveness of the accounting courses.

Originality/value

The accounting literature shows that there have been efforts by accounting researchers to measure the understandability of accounting texts or narratives. This research provided valuable insights of the learning challenges of international students and valuable recommendations to educators and publishers to enhance the delivery.

Abstract

A semi‐analytical integration technique to evaluate the singular integration in 3‐D boundary element method for electromagnetic field computation is reported. The technique has been applied in a hybrid finite element—boundary integral model to evaluate the singular integral terms when constructing the “outside stiffness matrix” in the case of small air‐gaps, and it has also been used to calculate the exterior magnetic field in the proximity of the boundaries. The comparison with the conventional Gaussian quadrature has been carried out by modelling a 3‐D magnetostatic problem with a small air‐gap.
