Abstract

Purpose

The aim of this paper is reviewing the discipline development course of the history of socialist political economy with Chinese characteristics and recognising the changes of its development and its historic mission in the new stage will be beneficial to the construction of socialist political economy with Chinese characteristics from the perspective of doctrinal history.

Design/methodology/approach

In this paper from the aspect of discipline formation and development, the history of China’s socialist political economy has experienced two stages: emergence and formation (the first stage) and steady development (the second stage). It has explored new research fields and improved the quality of research levels. However, the role of studying the history of socialist political economy with Chinese characteristics has not been fully played regarding satisfying the needs of constructing socialist political economy with Chinese characteristics.

Findings

In this study when the construction of socialist political economy with Chinese characteristics entered a new era, the study of the history of socialist political economy also entered a new stage, showing new features in terms of research objectives, principles, scale and methods.

Originality/value

Therefore, the research on the history of socialist political economy with Chinese characteristics should be highly emphasised, and the focus on serving the construction of socialist political economy with Chinese characteristics should be its historic mission and core task. Also, researchers should pay attention to changing ideas, laying a good foundation, highlighting key points, building platforms and broadening horizons.

Abstract

Purpose

This paper aims to promote an expanded two‐way dialog between Chinese and Western leaders and executives which recognizes that “wisdom” can flow in both directions.

Design/methodology/approach

Interviews were undertaken with three Chinese executives and analyzed against a model of performance excellence.

Findings

An understanding of some of the similarities and differences of Western and Chinese business practices and a conclusion that there are lessons for Western businesses to learn.

Research limitations/implications

The work involved interviews with only three Chinese executives and thus represents a tiny sample.

Practical implications

Illustrates some of the practices that might be worth considering by the West as we climb out of the current economic depression and re‐focus business efforts for a longer‐term future.

Originality/value

The paper adopts a novel approach of analyzing interview outcomes against a reference model. The core value is, however, in highlighting the benefits that might arise from extended dialog.

Abstract

Purpose

This paper aims to propose a fast and robust 3D point set registration method for pose estimation of assembly features with few distinctive local features in the manufacturing process.

Design/methodology/approach

The distance between the two 3D objects is analytically approximated by the implicit representation of the target model. Specifically, the implicit B-spline surface is adopted as an interface to derive the distance metric. With the distance metric, the point set registration problem is formulated into an unconstrained nonlinear least-squares optimization problem. Simulated annealing nested Gauss-Newton method is designed to solve the non-convex problem. This integration of gradient-based optimization and heuristic searching strategy guarantees both global robustness and sufficient efficiency.

Findings

The proposed method improves the registration efficiency while maintaining high accuracy compared with several commonly used approaches. Convergence can be guaranteed even with critical initial poses or in partial overlapping conditions. The multiple flanges pose estimation experiment validates the effectiveness of the proposed method in real-world applications.

Originality/value

The proposed registration method is much more efficient because no feature estimation or point-wise correspondences update are performed. At each iteration of the Gauss–Newton optimization, the poses are updated in a singularity-free format without taking the derivatives of a bunch of scalar trigonometric functions. The advantage of the simulated annealing searching strategy is combined to improve global robustness. The implementation is relatively straightforward, which can be easily integrated to realize automatic pose estimation to guide the assembly process.

Abstract

Purpose

Aiming at improving the mechanical efficiency, the applicability and the working life of high water-based hydraulic motor (HWBHM) under working conditions at low speed and high pressure, the friction performance of different matching materials for piston slipper – crankshaft pair with high water-based hydraulic fluid (HWBHF) under working conditions at low speed and high pressure – were studied.

Design/methodology/approach

The friction experiments for different materials (316L, 316L with surface coating OVINO – tetrahedral amorphous carbon [TAC; 316L-TAC] – 316L with surface coating OVINO-graphite intercalated compound [GIC; 316L-GIC] and polyetheretherketone [PEEK] reinforced with 30 per cent carbon fiber [PEEK-30CF]) under HWBHF lubrication were implemented on a pin-disk friction abrasion machine to determine the variations of coefficient of friction (CoF) and wear rate for each matching materials. In addition, the roughness and the morphology of worn surface of different matching materials were quantitatively characterized.

Findings

The study revealed that material combinations have different friction performances. Test results showed that the abrasion of matching type stainless steel (SS) and SS is rather serious, and the method of surface coating could improve the friction performance of SS when friction with other materials. For matching type of SS with surface treatment (SS-ST) and SS-ST, 316L-GIC and 316L-GIC have relatively stable CoF, and the wear rate was smaller than other matching materials, while 316L-TAC and 316L-TAC has the smaller CoF than that of 316L-GIC. Matching materials 316L-GIC with PEEK-30CF of matching type SS-ST and PEEK-30CF has more stable COF and better wear resistance than those of other matching materials.

Originality/value

This research has laid a foundation for the improvement of service life and working efficiency of friction pair in HWBHM under working conditions at low speed and high pressure.

Abstract

Purpose

The purpose of this paper is to study the managing of emergencies pertinent to public health which is critical to the well‐being of a society; as such, the management mechanisms employed should be of great interest and significance for research.

Design/methodology/approach

This paper first relies on extensive literature to describe the mechanism used in the USA from three aspects – organizational structure, management system, and logistics network. For the purpose of comparison, the Chinese version of the mechanism is presented from the same three aspects. The two management systems are then compared both qualitatively and quantitatively.

Findings

Deficient areas in Chinese public‐health management mechanism as well as challenging issues associated with supply chain design and coordination for emergency supplies in the context of large‐scale public health emergencies with low frequency but catastrophic impacts are found. Specifically, the following three important research problems are revealed from the comparative study: how to establish an efficient organizational structure that incorporates all the relevant entities in public‐health emergency management? How to establish an information system for emergency management that integrates disease surveillance, control, and prevention? How to design an efficient and cost‐effective logistics network to ensure prompt and sufficient delivery of emergency supplies?

Originality/value

To date, this research has been the first of its kind that compares two countries' emergency management systems in the context of public health management.

Abstract

Purpose

This paper aims to present an 8 kW LLC resonant converter designed for plasma power supply with higher efficiency and lighter structure. It presents how to solve the problems of large volume and weight, low performance and low efficiency of traditional plasma power supply.

Design/methodology/approach

At present, conventional silicon (Si) power devices’ switching performance is close to the theoretical limit determined by its material properties; the next-generation silicon carbide (SiC) power devices with outstanding advantages can be used to optimal design. This 8 kW LLC resonant converter prototype with silicon carbide (SiC) power devices with a modulated switching frequency ranges from 100  to 400 kHz.

Findings

The experimental results show that the topology, switching loss, rectifier loss, transformer loss and drive circuit of the full-bridge LLC silicon carbide (SiC) plasma power supply can be optimized.

Research limitations/implications

Due to the selected research object (plasma power supply), this study may have limited universality. The authors encourage the study of high frequency resonant converters for other applications such as argon arc welding.

Practical implications

This study provides a practical application for users to improve the quality of plasma welding.

Originality/value

The experimental results show that the full-bridge LLC silicon carbide (SiC) plasma power supply is preferred in operation under conditions of high frequency and high voltage. And its efficiency can reach 98%, making it lighter, more compact and more efficient than previous designs.
