When solving the cogging torque of complex electromagnetic structures, such as consequent pole hybrid excitation synchronous (CPHES) machine, traditional methods have a huge computational complexity. The notable feature of CPHES machine is the symmetric range of field-strengthening and field-weakening, but this type of machine is destined to be equipped with a complex electromagnetic structure. The purpose of this paper is to propose a hybrid analysis method to quickly and accurately solve the cogging torque of complex 3D electromagnetic structure, which is applicable to CPHES machine with different magnetic pole shapings.

In this paper, a hybrid method for calculating the cogging torque of CPHES machine is proposed, which considers three commonly used pole shapings. Firstly, through magnetic field analysis, the complex 3D finite element analysis (FEA) is simplified to 2D field computing. Secondly, the discretization method is used to obtain the distribution of permeance and permeance differential along the circumference of the air-gap, taking into account the effect of slots. Finally, the cogging torque of the whole motor is obtained by using the idea of modular calculation and the symmetry of the rotor structure.

This method is applicable to different pole shapings. The experimental results show that the proposed method is consistent with 3D FEA and experimental measured results, and the average calculation time is reduced from 8 h to 4 min.

This paper proposes a new concept for calculating cogging torque, which is a hybrid calculation of dimension reduction and discretization modules. Based on magnetic field analysis, the 3D problem is simplified into a 2D issue, reducing computational complexity. Based on the symmetry of the machine structure, a modeling method for discretized analytical models is proposed to calculate the cogging torque of the machine.

The purpose of this paper is to focus on the machine design and control strategy of the permanent magnet synchronous generator (PMSG) system, especially utilized in variable speed applications, in order to stabilize the output voltage on the dc link over a wide speed range.

Different ac/dc power converter topologies are comparatively studied, each with an accordingly designed PMSG, so as to investigate the influence of the armature winding inductance as well as the relationship between the PMSG and power converter topologies.

Pulse width modulation (PWM) rectifier is preferable for the said application due to its good performance and controllability. Moreover, by employing the PWM rectifier, relatively large inductance of the PMSG is considered for both short-circuit current reduction and field regulation.

Field-regulating control is realized with a space vector PWM (SVPWM) rectifier, which can weaken the PMSG magnetic field during high-speed operation, while even properly enhance the field at low speed, ensuring a small change of the PMSG output voltage and a stable dc voltage.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

In order to keep the advantages of PM generators and eliminate its disadvantage – difficulty in regulating the magnetic field, hybrid excitation is an effective way. The purpose of this paper is to propose a novel way to achieve hybrid excitation by use of tooth harmonic field.

Unlike weakening the tooth harmonics field and EMF in traditional machines, in this paper the tooth harmonics field is proposed to form a novel hybrid excitation permanent magnet synchronous generator (HEPMSG).

The generation mechanism of tooth harmonic electromotive force (EMF) of rotor winding is introduced, and its influencing factors are discussed in detail. The matching design of tooth harmonic winding and field winding for maximum output field current of tooth harmonic excitation system is analyzed.

This machine can achieve not only effective adjustment of the air-gap magnetic field, but also elimination of the brushes and slip rings.

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

The purpose of this paper is to focus on various control strategies for permanent magnet synchronous generator (PMSG) systems, in order to stabilize the dc link output voltage over a wide operation speed range.

Two control methods, namely, the flux regulation control (FRC) which adjusts the stator flux linkage and then indirectly stabilize the dc link voltage, and the direct voltage control (DVC) which directly stabilize the dc link voltage by regulating the power angle, are proposed in this paper. Both methods can be realized by either approach of the conventional space vector pulse width modulation (SVPWM) or the proposed single voltage vector modulation (SVVM).

The FRC can optimize the field in the PMSG, however, the realization is complicated. The DVC need not estimate and regulate the stator flux linkage, hence is easy to implement. On the other hand, the SVPWM can provide smooth armature current and dc link voltage, while the SVVM applies only one voltage vector during each control cycle, hence, is simple to realize and requires the minimum switching on the PWM rectifier. All cross-combinations between the two control methods and the two realization approaches work well.

The proposed FRC and DVC methods are simpler than the conventional field oriented control, while the proposed SVVM is a novel and efficient approach to generate the PWM status. Optimal cross-combination, either of SVPWM-FRC, SVVM-FRC, SVPWM-DVC and SVVM-DVC, can be chosen to satisfy the system characters and requirements.

The present study aims to seek the strategic analysis of the entrepreneurship of agricultural colleges (AC).

In terms of approach, this research was a combination of exploratory and hybrid methods. The present study was conducted in four stages. In the first stage, an open-ended questionnaire was designed to identify the strengths, weaknesses, opportunities and threats of entrepreneurship in AC (qualitative method). In the second stage, the Delphi-Fuzzy questionnaire was designed based on the results obtained from the first stage. In the third stage, the criteria of strengths, weaknesses, opportunities and threats of entrepreneurship of AC were analyzed based on the pairwise comparison (quantitative method) by the sample using a fuzzy hierarchical analysis process (FHAP). In the fourth stage, presented strategies were ranked based on pairwise comparison using FHAP.

From the analysis of weaknesses, strengths, opportunities and threats facing AC for entrepreneurship, 12 strategies were presented in 4 groups of aggressive, conservative, competitive and defensive.

The literature review showed that no research has been done so far to identify strengths, weaknesses, opportunities and threats facing university entrepreneurship, especially AC. So the present study analyzes the weaknesses, strengths, opportunities and threats and proposes practical strategies for moving toward the formation of entrepreneurship AC. According to the gaps in providing SWOT of the AC, the results of this research can pave the way for policy makers and planners in this field.

Uninterruptible Power Supply (UPS) systems are typically designed to provide power to computers for five to thirty minutes after all utility company power has failed. In addition to providing blackout and brownout protection, many UPS systems also protect against spikes, surges, sags, and noise, and some also offer many of the features found in power distribution units (PDUs). The major components or subsystems of a typical UPS system are detailed, and a sample bid specification is appended. Three sidebars discuss UPSs and air conditioning, the maintenance bypass switch (MBS), and literature for further reading.

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

Knight's Industrial Law Reports goes into a new style and format as Managerial Law This issue of KILR is restyled Managerial Law and it now appears on a continuous updating basis rather than as a monthly routine affair.

The purpose of this paper is to explore the role of international law in disaster prevention and management, with a particular focus on the emerging field of international disaster law (IDL), and its relationship with international human rights law. It further introduces the four articles of the special column of this journal issue, dedicated to disasters and international law.

The analysis is based upon primary sources of legislation and policy, as well as academic literature on disasters and international law.

Although the field of IDL is in its infancy, the authors argue that this emergent area does have the potential to gain widespread recognition as a distinct field of law, and that this may benefit the wider disaster management community.

The paper introduces key legal features and themes relating to international law and disasters, highlighting their relevance for disaster management. The added value is to widen the discussion on aspects of disasters regulated by international law, thus facilitating the future exchange with other academic subjects and operational fields.

The purpose of this study is to propose a modeling method of the equivalent circuit for a new type of high-temperature superconducting partial-core transformer (HTS-PCT) made of ReBCO-coated conductors.

The modeling process is based on the “Steinmetz” equivalent circuit. The impedance components in the circuit are obtained by the calculations of the core losses and AC losses of the HTS windings by using theoretical methods. An iterative computation is also used to decide the equivalent resistances of the AC losses of the primary and secondary HTS windings. The reactance components in the circuit are calculated from the energy stored in the magnetic fields by finite element method. The validation of the modeling method is verified by experimental results

The modeling method of the equivalent circuit of HTS-PCT is valid, and an equivalent circuit for HTS-PCT is presented.

The equivalent circuit of HTS-PCT could be obtained by the suggested modeling method. Then, it is easy to analyze the characteristics of the HTS-PCT by its equivalent circuit. Moreover, the modeling method could also be useful for the design of a specific HTS-PCT.

The study proposes a modeling method of the HTS-PCT made of the second-generation HTS tapes, i.e. ReBCO-coated conductors.

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Microfinance institutions (MFIs), including Islamic microfinance institutions (IMFIs) in Muslim countries, have spread across the globe and transformed into a new industry. However, how IMFIs in Indonesia evolved to become an important sector serving society has not been rigorously explored. Therefore, the purpose of this paper is to address the lacuna on the emergence of an industry by examining the development of Islamic microfinance sector in Indonesia.

The paper adopts the historical research method to narrate the evolution of this specific sector based on the data collected through oral history and published academic research documents during various periods of Indonesia’s economic and political milieu.

This paper demonstrates that the emergence and development of IMFIs in Indonesia has been shaped within the wider process of socio-political changes, particularly, the role of Islamic movement and politics in Indonesia.

Most studies investigating the emergence and transformation of institution or industry adopt the static approach, which has been criticised as it fails to consider the process of emergence, growth path and the survival of organisations. Hence, this paper contributes to the literature by analysing the institutional evolution by locating the institution inside its wider environmental context by using Bourdieu’s concept of field to narrate the historical development of IMFIs from its emergence and evolution to become a significant new industry in the country.

This study offers a Bourdieu-oriented analysis of the tax compliance practice for indigenous entrepreneurs in New Zealand. It examines the intersection of accounting and tax for Māori entrepreneurs and their relational interactions with the Inland Revenue Department (IRD)/state/Crown and accountants by considering the contextual factors of history, culture and society of Māori.

Qualitative research was adopted using face-to-face in-depth interviews with 34 participants and reviewing government documents. The authors analyse the tax compliance practice by drawing on Bourdieu's concepts of field, capital and habitus to conceptualise the tax field as a site of struggle for power and control by the IRD, accountants and indigenous entrepreneurs.

This study demonstrates how the tax field is structured as a game between tax reporting, taxpaying and monitoring functions. The position within the field is determined by the actor's access to the relevant capitals and habitus. It identifies how accounting, given its centrality to tax compliance, facilitates the power relations between the IRD, accountants and Māori entrepreneurs. The Eurocentric accounting-based tax reporting and the contextual factors illuminate how indigenous entrepreneurs are being dominated in the tax field. They experienced cultural dissonance with conflicting responsibilities when traversing the collectivistic indigenous and tax fields. Their collectivism involves sharing resources as they cherish whanaungatanga (relationship, kinship) and manaakitanga (kindness, generosity), which are at odds and are not valued in the tax field.

It is an empirical illustration of the connection between accounting, tax and power for indigenous taxpayers and their relationship with the IRD/Crown and accountants. It has practical implications for developing and enhancing tax compliance in jurisdictions with indigenous taxpayers. Such an understanding is helpful for policymakers, government, business agencies and the accounting professions when assisting, empowering and educating indigenous groups regarding tax compliance.

This paper responds to the call for accounting research with modern-day indigenous peoples rather than historical ones. The paper fills a gap in the accounting and tax literature by examining the tax compliance practice of indigenous small and medium enterprise (SME) entrepreneurs using Bourdieu's framework. It identifies how the role of accounting creates, maintains and reinforces power structures in the tax field. Tax/accounting reporting based on Eurocentric rules disempowers and alienates indigenous entrepreneurs. They misrecognise their actions in reproducing the existing power structures in the tax field due to deeply held historical and cultural factors about the fear of the Crown/state and their practice of rangitaratanga (esteeming authorities).

The purpose of this paper is to provide a parallel review of the role and processes of monitoring and regulation of corporate identities, examining both the communication and the performance measurement literature.

Two questions are posed: Is it possible to effectively monitor and regulate corporate identities as a management control process? and, What is the relationship between corporate identity and performance measurement?

Corporate identity management is positioned as a strategically complex task embracing the shaping of a range of dimensions of organisational life. The performance measurement literature likewise now emphasises organisational ability to incorporate both financial and “soft” non‐financial performance measures. Consequently, the balanced scorecard has the potential to play multiple roles in monitoring and regulating the key dimensions of corporate identities. These shifts in direction in both fields suggest that performance measurement systems, as self‐producing and self‐referencing systems, have the potential to become both organic and powerful as organisational symbols and communication tools. Through this process of understanding and mobilising the interaction of both approaches to management, it may be possible to create a less obtrusive and more subtle way to control the nature of the organisation.

This paper attempts the theoretical and practical fusion of disciplinary knowledge around corporate identities and performance measurement systems, potentially making a significant contribution to understanding, shaping and managing organisational identities.

This chapter examines the UK and the Nigerian approach to reducing emission of greenhouse gases (GHGs) into the environment as a result of gas flaring utilising the market-based regulation. Determining how different jurisdictions fare in the quest to reduce GHG emissions associated with the oil and gas industry is essential because: policy makers have realised the advantages of market-based regulation over the command-and-control regulation; and in the light of various pledges different countries have made in different forum to reduce the emission of GHGs, particularly in the wake of the recently held Paris climate change conference.

Library-based approach is used, providing conceptual and theoretical understanding of climate change, GHG emissions and various market-based regulatory tools utilised in the United Kingdom and Nigeria in regulating emission associated with operations in the oil and gas industry.

The study reveals the significance of environmental regulations that encourage region integration and flexibility in the implementation of environmental policies. Moreover, it finds that the Paris Agreement re-affirms the utilisation of market-based regulations and indicates a future for investment in the oil and gas industry.

The study revealed that there are lacunas in regulations and strategies for the implementation of environmental regulations which need to be addressed in order to achieve zero or a significant decrease in gas flaring.

This study provided an ample opportunity to theoretically examine market-based regulatory tools utilised in the oil and gas industry in a developed country in relation to a developing country.

This study aims to identify institutional work mechanisms that public actors employ in market shaping.

The paper uses an abductive theorizing process, combining a literature review with an empirical exploration of three different market-shaping contexts.

The study identifies 20 granular mechanisms of institutional work that market-shaping public actors employ. These mechanisms are all potentially employable in creating, maintaining or disrupting markets. Institutional work vis-à-vis individual institutions may differ in direction from the institutional work vis-à-vis the market system. Public actors are not a homogeneous group but may have different values and support competing institutional logics even when operating in the same market.

The empirical data were limited to three cases in three small open economies. Data collected from other markets and with other methods would provide more rigorous insight into market-shaping public actors.

The findings revealed institutional work mechanisms that public actors can use to shape markets. Companies wanting to engage public actors in market shaping should be aware of the values and institutional logics that influence market-shaping public actors.

The paper unites and expands on the scattered knowledge regarding institutional work in market shaping. It illuminates and dissects the role of public actors in market shaping, challenging the reactive stance that is often assigned to them. The study provides a better understanding of how conflicting market views affect markets. It also brings insights into the interplay between market-shaping actions and the multiple levels of market systems.
