This paper introduced a novel forecasting method, Support Vector Regression with Local Predictor (SVRLP), which aims to forecast the short-term load distribution function. To increase the forecast accuracy, the conventional Support Vector Regression (SVR) is combined with a phase space reconstruction technique, called local predictor. This proposed forecast method can be applied to forecast the load...
The accurate detection and location of a fault is crucial for power systems applications such as protective relaying and phasor measurement. As fault signals have unique mathematical expressions, this paper proposes a computational intelligence based method to estimate the parameters of the fault signal towards the minimum difference between the input signal and the reconstructed one. The optimization...
The deployment of modern DFIG or full converter turbine technologies on a large scale into distribution networks is raising issues for electric utilities with regard to voltage rise and flicker amongst other power quality issues. This paper proposes an real-time reactive power coordination scheme employed with the voltage control technique, the concurrent means for achieving both voltage regulation...
SiO2 nanoparticles as platform for delivery of 3′-triazole analogues of AZT-triphosphate into cells were proposed. The results confirmed the successfulness of the Huisgen's 1,3-dipolar cycloaddition reaction for the preparation of the SiO2∼dNTP nanocomposites. It was shown that polymerase can recognize nucleoside triphosphates in the proposed nanobiocomposites and incorporate them into the growing...
This study is focused on an evaluation of public transit coordination between public bus and railway under different operation strategies between two operators. The policies of the operators in a multimodal and multi-operator transit system are categorised into three different strategies, namely cooperation, competition and independence. Each strategy is analysed in three coordination scenarios of...
A novel all-solid-state microsupercapacitor (MSC) with ∼70-µm-thick three-dimensional electrodes consisting of activated carbon (AC) particles and polymer electrolyte (PE) was fabricated and tested in this study. Unique features of the present MSC design include: (i) a novel electrode material composed of PE and AC particles, which enhances the accessibility of the surface of AC particles by ions...
This paper reports a surface-mount flexible micro-supercapacitor employing a thin parylene-C membrane (10 µm) as the substrate and activated carbon (AC) as the electrodes. A thin parylene-C layer was deposited on a Si wafer by chemical vapor deposition (CVD) without silanization and then peeled off mechanically with the fabricated interdigital electrodes on it. The prototypes show a specific capacitance...
This paper represents a low cost printed Vivaldi antenna at 3–10 GHz bandwidth for Radio telescope Feed system. The idea of this design is to minimize the number of telescope receivers for Square Kilometre Array (SKA) [1]. A minimized tapered slot antenna with a balun feed for receiver systems is proposed. The Vivaldi antenna is design on a relatively low dielectric constant substrate which operates...
The ferromagnetic resonance frequency fFMR of soft magnetic films (SMFs) can be expressed by the Kittel equation. Clearly, high 4pMS and HK are needed to achieve a high fFMR in SMFs. Previous research on achieving high fFMR SMFs has mostly been focused on enhancing uniaxial magnetic anisotropy field HK since it is relatively easier to be enhanced by 1–2 orders of magnitude, compared to saturation...

The structure of the motor for the power generation system is also...
The growth in the use of implanted medical devices, mobile devices and electric vehicles is exciting interest in wireless power transfer system. Wireless power transfer system (WPT) via magnetic resonant coupling was firstly proposed in 2007, and the system can transfer power to the receiving device over a distance of several times of the radius of the coils [1]. The WPT is not sensitive to the biological...
Soft magnetic films (SMFs) are key materials for miniaturization and multifunctionality of radio frequency and microwave components and integrated circuits (ICs) due to the good high-frequency soft magnetic performances and the compatibility to IC processing technologies. Magnetic micro-inductors are one of widely used microwave IC components. The SMFs in magnetic micro-inductors should have a well-defined...

Modern electronic products are heading towards...
This paper mainly discusses the design and implementation of semi-automatically simultaneous localization and mapping (SLAM). SLAM is an important technique for home service robots to move in unknown environments and built the environment map. Different from traditional SLAM method which is operated by a remote controller, the semi-automatically SLAM is operated by human-robot interaction. The semi-automatically...
The tunnel magnetoresistance (TMR) effect has attracted significant attention in recent years not only due to the extensive applications of the magnetic tunnel junctions (MTJs) but also for the understanding of the complex physics of spin dependent transport [1]. There has been an increasing amount of evidence that the TMR of MTJs is strongly influenced by the interface between magnetic electrodes...
Orthoferrites RFeO3(except R=Y, La and Lu) possess two sets of magnetic sublattice, that is, Fe3+ sub-system and R3+ sub-system. Magnetic properties and interactions between the two sub-systems including Fe-Fe, R-Fe, and R-R interactions depend on external parameters, such as temperature, magnetic field, etc.[1-3] So real magnetic materials can exhibt rich low temperature characteristics. We have...
Due to significant application in medical treatment, magnetic record and cryogenic magneto-refrigeration, a great amount of researches on ferromagnetic nanoparticles were executed [1]. With decrease of the scale of ferromagnetic material, the magnetic order and magnetization gradually decrease and such decrease is attributed to the increasing surface disorder or surface spin canting. However, for...

In this paper, two methods to reduce the complexity of multi-parametric programming model predictive control are proposed. We show that the standard multi-parametric programming problem can be modified by approximating the quadratic programming constraints. For a certain control sequence, only constraints on the first element is considered, while constraints on future elements are ignored or approximated...
