TL;DR: This paper reviews and compares 6LoWPAN and LPWAN in terms of network architecture, protocol stack, applications and security.
Abstract: By 2020, 50 billion devices (things) are expected to be connected to the Internet to form the Internet of Things (IoT) world. In general, two main categories of networks are used in the IoT: short-range and long-range low-power networks. IPv6 over low-power wireless personal area networks (6LoWPAN) are considered to be a crucial network in short-range low-power networks where 6LoWPAN motes will account for the majority of short-range low-power things. Also, LoRaWAN and SigFox are two major networking landscapes and players in long-range, low-power networks or oftentimes called low-power wide area networks (LPWAN). This paper reviews and compares 6LoWPAN and LPWAN in terms of network architecture, protocol stack, applications and security. In general, LPWAN networks are more demanding in terms of node and link constraints than 6LoWPAN networks (e.g. very low payload size, very low data rate and very limited resources). Also, as yet, LPWAN networks do not have IPv6 addressing capabilities. Each network category has its unique characteristics and strengths and each category has its important role in the IoT world.

TL;DR: In this article, the authors examined the practicality of estimating the number of broken rotor bars using stator current and axial leakage flux measurements and compared with theoretical predictions and empirical results from other researchers.
Abstract: Spectrum analysis of the stator current is commonly used for detecting broken rotor bar faults in induction motors. In this paper we examine the practicality of estimating the number of broken bars using stator current and axial leakage flux measurements. The work is based on experimental current and flux measurements taken from induction motors as the number of broken rotor bars is progressively increased. The test results are compared with theoretical predictions and empirical results from other researchers. The effect of partial load operation is also examined.

TL;DR: Backtracking search algorithm (BSA) is applied to solve the ORPD problem to minimise the power losses and/or improve the voltage profile under control and dependent variable constraints.
Abstract: Optimal reactive power dispatch (ORPD) problem has a mounting effectuation on secure and economical operation of electrical power systems. It is well-known as a non-linear, multimodal and mixed-variable problem which has been solved using various computation intelligence-based techniques in the last decades. In this paper, as a new approach, backtracking search algorithm (BSA) is applied to solve the ORPD problem to minimise the power losses and/or improve the voltage profile under control and dependent variable constraints. The BSA is a new evolutionary algorithm for solving real-valued numerical optimisation problems. It has a simple structure and single control parameter. It memorises a population from a randomly chosen previous generation for use in generating the search-direction matrix. This grants BSA the advantage of experiences gained from previous generations to generate the offsprings. The proposed BSA is applied to the IEEE standard 30-bus system, and a real power system at West Delta ...

TL;DR: In this paper, a review of the application of soft magnetic composite (SMC) materials in electrical machines is presented, both successful experiences and existing difficulties are discussed, and possible further work required for the commercial success of SMC machines is proposed.
Abstract: Soft magnetic composite (SMC) materials and their uses in electrical machines have undergone significant development in the past decade. The major advantages of the materials include isotropic magnetic and thermal properties, very low eddy current loss and relatively low total core loss at medium and higher frequencies, and low cost fabrication with good tolerance and surface finish using the well developed powder metallurgical techniques that require no further machining. It is even anticipated that the application of SMC may lead to a revolutionary development in the electrical machine manufacturing industry. This paper reviews the application of SMC in electrical machines. Both successful experiences and existing difficulties are discussed, and possible further work required for the commercial success of SMC machines is proposed.

TL;DR: In this paper, a three-phase permanent magnet claw pole motor with soft magnetic composite stator was developed, taking advantage of the unique properties of the material, such as the three-dimensional finite element analysis of magnetic fields for parameter calculation and dimension optimisation, rotational core loss models combined with finite element method for core loss prediction, and hybrid thermal model with distributed heat sources for the temperature rise calculation.
Abstract: This paper reports the development of a three-phase permanent magnet claw pole motor with soft magnetic composite stator, taking advantage of the unique properties of the material. Advanced design and performance analysis methods were employed, such as the three-dimensional finite element analysis of magnetic fields for parameter calculation and dimension optimisation, rotational core loss models combined with finite element method for core loss prediction, and hybrid thermal model with distributed heat sources for the temperature rise calculation, etc. The design and analyse methods are validated by experiment on the prototype driven by a brushless DC drive scheme.
