Noninvasive detection of artificial heart valve outlet strut fracture using sweep frequency eddy current testing
Authors: Strapacova Tatiana , Capova Klara
Published: December 2018

The paper proposes utilization of eddy current inspection for detection of defects in the artificial heart valve. Artificial heart valves are prosthetic replacements which are used if the function of the natural heart valve is limited. A special type of prosthetic heart valve replacements is the Björk Shiley convexo-concave (BSCC) heart valve. The fractures of the BSCC artificial heart valve usually affect the outlet strut. If the fracture of the strut is not detected in time the patient can die of heart attack. Detection of the fracture in the outlet strut is the concern here. Experimental measurements are performed in order to evaluate the detection capability of the technique and the sensitivity of response signal to dimensional parameters of a fracture. A BSCC heart valve prototype having the electromagnetic characteristics of the Co-Cr (Hayness 25) alloy is inspected with a probe. A non-conductive defect is positioned in the outlet strut and its dimensions are varied. The probe is positioned above the centre of the crack and the frequency of exciting signal is changed in a wide range. The presented results demonstrate that the sweep frequency technique can enhance eddy current inspection of a defect in BSCC heart valve.

Published: December 2018

Purpose of the paper is to study the behaviour of a submerged arc furnace for the production of ferroalloys in order to implement a new voltage-based control system of the furnace. A 3D Finite Element (FE) model has been developed to define an equivalent electric circuit model able to describe the furnace operations. Both field and circuit models are validated by measurements on a furnace installed in an industrial plant. A novel method to control a furnace is proposed.
Fast analysis of metallic antennas by parallel moment method implemented on CUDA
Authors: Kiss Imre , Benkö Péter Tamás , Gyimóthy Szabolcs
Published: December 2018

In this paper a modeling technique enabling the fast analysis of antenna arrangements built-up from metallic parts is presented in detail. A calculation method which accelerates the solution of integral equations discretized by the Method of Moments have been implemented in a massively parallel computing environment, a general purpose video card (GPU). Rao-Wilton-Glisson edge basis functions are used to expand surface currents, while radiated field is computed using the dipole model. Since the entire computation takes place on the GPU exclusively, the overall computational time could be significantly reduced. To obtain such an acceleration, a novel computational technique is proposed for the filling of the impedance matrix, which takes full advantage of the given platform.
Improvement of operating state by switching two phase-advanced capacitors to an ac ampere type linear magnetic levitation system
Authors: Ohji Takahisa , Miao Zhen , Matsushima Koji , Amei Kenji , Sakui Masaaki
Published: December 2018

This paper describes the operating state improved by using phase-advanced capacitors for the ac induction type magnetic levitation(maglev) system. In case many coils are set up in yoke such as this type of maglev, the impedance of electric circuit of the stator has strong inductivity; therefore, a phase-advanced capacitor should be inserted to achieve power-saving operation for the inductive circuit. However, the ferroresonance state occurs as the power-factor of the circuit approaches 1, and then the current steeply increases even if the voltage increases slowly. Thereby, a non-magnetic plate greatly oscillates when it starts to levitate. To improve the starting oscillation, we adopted the method of switching two different capacitors. As a result, both smooth starting of levitation and minimum input power operation functioned successfully.
Influence of the objective function in the process of optimal design of an electromagnetic measurement system
Authors: Cundeva-Blajer Marija , Arsov Ljupco
Published: December 2018

In the paper an analysis of the influence of the objective function during the process of metrological optimal design of an electromagnetic measurement system is made. The case study is a combined measurement transformer. The optimal design of the transformer is made by using an original program based on the genetic algorithm. Four different objective functions comprising the main metrological parameters of the transformer (voltage and phase displacement error of the voltage measurement core and current and phase displacement error of the current measurement core) are posed for the optimal design. Two metrological approaches are embedded in the objective functions: 1) the conservative (with certain measurement errors) and 2) the Guide EA-4/02 "Expression of the Uncertainty of Measurements in Calibration" (GUM) statistical approach. The optimal design solutions derived for the different objective functions are compared and discussed.
MRI signal computing by integral and finite element methods
Authors: Abidi Zakia , Bandelier Bernard , Djennah Mohammed , Rioux-Damidau Françoise
Published: December 2018

A numerical technique, based on the combination of a finite element method and a boundary integral method has been developed to compute the induced signal in MRI antennas. This signal rises from a free movement of precession of the transverse magnetization of the sample to explore. In our modeling, the transverse magnetization represents the magnetic source field. Its flux embraces the antenna to give rise to a sinusoidal current which is very quickly attenuated in time (a few ms); it represents the signal containing all the informations of the sample. We here want to find the geometrical and electromagnetic characteristics of the antennas which permit to have a signal to noise ratio as great as possible. In our computation, we have taken into account leading factors such as the distance between the probe and the organ to be explored and also the geometrical and electromagnetic characteristics of the probe.

Authors: Ito Yasuhisa , Igarashi Hajime , Watanabe Kota , Iijima Yosuke , Kawano Kenji
Published: December 2018

This paper presents a non-conforming finite element (FE) method with tetrahedral elements, which is applied to 3-D shape optimization. In the present method, continuity of magnetic flux is directly enforced on the interfaces of different domains in which FE meshes are independently generated. The slave unknowns in one side which are linearly dependent on the unknowns in the other side are eliminated. It is shown that the present method yields accurate solutions to 3-D nonlinear magnetostatic problems. Moreover, evolutional shape optimization of an inductor is shown to be successfully carried out using the present method.
Three dimensional optimization using voxel-based finite element method with homogenization
Authors: Sato Takahiro , Watanabe Kota , Igarashi Hajime , Iijima Yosuke , Kawano Kenji
Published: December 2018

In parameter optimization using the finite element method (FEM), re-meshing with long computational time must be performed many times. Although voxel-based FEM is one of the effective techniques to avoid the re-meshing, it has less accuracy in comparison with the conventional FEM because of stair-shaped boundaries. In this work, to improve the computational accuracy in the voxel-based FEM, a new homogenization method is presented. In the present method, the effective reluctivity of finite elements at material interfaces is determined on the basis of magnetic circuit. The present method is successfully applied to three dimensional shape optimization of an inductor model.

Authors: Choi Myoung-Hyun , Rhyu Se-Hyun , Kim Byung-Taek
Published: December 2018

In this paper, various effective and oscillatory torque components in a line-start permanent magnet (LSPM) motor are analyzed using the principle of superposition through the analytic approach with an equivalent circuit. According to the independent sources, in the asynchronous speed the induced rotor current and braking stator current are derived by using the DQ equivalent circuit and Laplace transformation. Then, two effective components and three oscillatory components of torque are calculated quantitatively by using the analytic torque equations. Finally, to check usefulness of the proposed method, the current and torque characteristics are compared with finite element analysis and measurement results for various speeds.

Authors: Choi Jae-Hak , Kim Dong-Jun , Chun Yon-do , Han Pil-Wan , Koo Dae-Hyun , Lee Ju
Published: December 2018

The approximate optimization based on a response surface modeling has been applied to the optimum design for obtaining flat torque of switched reluctance motor, which has high fluctuating torque due to its inherent salient structure. In order to reduce the fluctuating torque ripple causing noise and vibration, an optimization design technique has been introduced and investigated to find geometric and electric variables by means of combining finite element analysis considering driving circuits and response surface modeling. In this research an effective optimization method based on a response surface modeling has been used to overcome the modeling noise in formulating an objective and constraint and the cumulative numerical inaccuracy.

Authors: Senol Seray , Ustun Ozgur
Published: December 2018

The paper presents a study on the design and analysis of a sub-fractional slot concentrated winding brushless direct current motor (BLDCM) with unequal tooth widths for a light electric vehicle application. This kind of brushless surface permanent magnet (SPM) motor is equipped with easy-to-manufacture features which are crucial for the electrical machinery market, especially for electric motors used in electric vehicles. The structure also responds quite effectively to field weakening operation, because of its inherent higher inductance value. The study is focused on increasing the winding inductance value by using the designs analysed in magnetic analysis software. A selected BLDC motor structure is manufactured and tested to verify the design.

Authors: Park Seong-Cheol , Choi Myoung-Hyun , Yuk Kyeong-Jin , Kim Byung-Taek
Published: December 2018

In this paper, the effects of magnetization on the rotor conductor of a written-pole motor (WPM) are analyzed and then the shape of the conductor to maximize the amount of the magnetization is designed while the magnet on the rotor is magnetized by an exciter pole. The optimization is performed with design variables that are the shape and number of the rotor bars, where an objective function is set to the amount of magnetization satisfying a constraint of the start-up time. The optimal design is verified by sequentially using a finite elements method and response surface method.

Authors: Nakamoto Hiroyuki , Takenawa Satoru , Kida Yasuaki
Published: December 2018

We propose a magnetic type tactile sensor that can measure a three-axis displacement and a three-axis force. The simple structure comprises two layers, an elastic layer and a substrate layer. The elastic layer is made of an elastic material and houses a cylindrical permanent magnet inside. The substrate layer is a glass epoxy board and has four giant magneto resistance(GMR) elements. The elements measure changes of magnetic field strength based on the displacement of the magnet, and the three-axis displacement and force are calculated from the outputs of the elements. Features of this sensor are a wiring reduction, simple structure, and low cost. In this paper, we describe a structure of the sensor. We design a sensor which has two magnets inside, and confirm the performances of a prototype through the laboratory experiments.

Published: December 2018

An accurate 3-D nonlinear transient finite-element model of an eddy current brake (ECB) has been developed, with consideration of the skin effect, eddy current distribution, nonlinear magnetization-saturation and rotation. Based on the analysis of the eddy current path (ECP) and penetration depth, the influence of principal parameters related to the braking process is analyzed. After analysis and comparison with the common round pole, a novel pole with sector shape has been developed, which brings about a significant increase of braking torque. An eight-pole ECB device with a peak torque of 4220 N · m under an excitation current of 88 A has been designed and tested for use in high-speed trains. The test results agree well with simulations.
Application of dynamic differential evolution for inverse scattering of a two-dimensional dielectric cylinder in slab medium
Authors: Huang Chung-Hsin , Li Ching-Lieh , Tuen Lung-Fai
Published: December 2018

In this paper, we apply the DDE algorithm to solve the inverse scattering problem for which a two-dimensional (2-D) dielectric cylinder with unknown cross section is buried in a dielectric slab medium. Finite difference time domain method (FDTD) is used to solve the scattering electromagnetic wave of a dielectric cylinder. The inverse problem is resolved by an optimization approach and the global searching scheme dynamic differential evolution (DDE) is then employed to search the parameter space. By properly processing the scattered field, some EM properties can be reconstructed. One is the location of the dielectric cylinder; the others are the shape of the dielectric cylinder and permittivity of the dielectric cylinder. This method is tested by several numerical examples, and it is found that the performance of the DDE is robust for reconstructing the dielectric cylinder. Numerical simulations show that even when the measured scattered fields are contaminated with Gaussian noise, the quality of the reconstructed results obtained by the DDE algorithm is very good.

Published: December 2018

This paper is concerned with the development of a soft palpation sensor for detection of prostatic cancer and hypertrophy. The sensor is a layered medium with two polyvinylidene fluoride (PVDF) films embedded in the matrix sponge rubber. It is pressed against the prostates and the output voltage signals from the polymer films are measured. The temporal mean values, {I}_1 and {I}_2 , of absolute voltage signals from the films are calculated and their ratio {I}_1/{I}_2 is used as the sensor output. First, the fundamental characteristics of a rectangular sensor with a plane surface are examined. Then, the surface geometry of the sensor was designed so that it clearly indicates the nature on the stiffness of the soft material. Finally, a compact cylindrical sensor attached to the doctor’s forefinger is described and experimental studies of its performance as a palpation sensor are presented. Some representative clinical data on the normal and hardened prostate glands are also presented.
Nonlinear waves in thermo-magnetoelasticity II. Wave generation in a perfect electric conductor
Authors: Ghaleb A.F. , Ayad M.M.
Published: December 2018

Relying on a nonlinear continuum model of thermo‐magnetoelasticity previously introduced by the authors, in which the heat capacity of the medium depends on strain and magnetic field, we investigate the effect of this dependence on the one‐dimensional propagation of nonlinear, thermo‐magnetoacoustic waves in an anisotropic (but centrosymmetric) half‐space of a perfect electric conductor permeated by a constant magnetic field. The obtained formula for the relative variation of the phase velocity of the wave due to this dependence may be used, in combination with the proper experimental data, to predict the value of a material constant.

Authors: Chiampi M. , Fuerntratt G. , Magele Ch. , Ragusa C. , Repetto M.
Published: December 2018

The use of a decision making scheme based on fuzzy logic applied to the design of electromagnetic devices is presented. In the Multi-Objective Optimisation, the different scalar objectives are merged together firstly by means of a fuzzyfication process and then by the application of a fuzzy logical operator. This scheme can be easily coupled to any search optimisation (zeroth order algorithm) since it does not require differentiation of the scalar functions. Two different implementations of the procedure, coupled to Simulated Annealing and to Genetic Algorithm stochastic search are presented. The two procedures are tested versus a two solenoids SMES (Superconducting Magnetic Energy Storage) Multi-Objective Optimisation problem.

Published: December 2018

A large number of methods for the design optimization have been proposed in recent years. However, it is not easy to apply these methods to practical use because of many iterations. So, in the design optimization, physical and engineering investigation of the given model are very important, which results in an overall increase in the optimization speed.

This paper describes a novel optimization procedure utilizing the conformal transformation method. This approach consists of two phases and has the advantage of grasping the physical phenomena of the model easily. Some numerical results that demonstrate the validity of the proposed method are also presented.

Authors: Yang J.S.
Published: December 2018

One-dimensional equations for the extension and flexure with shear deformations of a piezoelectric beam with rectangular cross section are derived from the three‐dimensional equations for linear piezoelectricity by double power series expansion in the thickness and width directions. The equations are reduced to the case of elementary flexure without shear deformations. As an application of these equations, the buckling of a ceramic piezoelectric beam is discussed.

Published: December 2018

A multilayer shielding system with five concentric cylinders of P-80 high-permeability material has been design and constructed in the Magnetometry Laboratory of our institute. The paper presents the results of the functional study of the shielding system. The P‐80 annealed alloy was especially elaborated for this application. The d.c. shielding effectiveness of the system is 3\times 10^{3} along the longitudinal axis and 5\times 10^{4} for the transversal direction. The a.c. shielding factor is studied for different frequencies. The remanent magnetic field inside the inner cylinder is in the order of units of nT, as a function of the deperming procedures. A mechanical device situated inside the shields allows the determination of the offset and magnetic noise of the fluxgate sensors, even in urban magnetically polluted conditions.

Pulse voltage operation of two-to-four-phase voltage-induction-type electrostatic motor
Authors: Yamashita Norio , Yamamoto Akio , Higuchi Toshiro
Published: December 2018

This paper analyzes pulse voltage operations of a two-to-four phase voltage-induction-type electrostatic motor (VITEM) to clarify the appropriate driving sequences. The paper also evaluates transient charge effects that can possibly enhance the thrust force. VITEM has been studied as a novel centimeter-sized electrostatic film motor whose power to the slider is supplied indirectly through its induction electrodes. Since a smooth synchronous driving was aimed in the past studies, high-frequency AC voltages have been used for the driving. This paper demonstrates that straightforward usage of simple pulse sequences cannot realize continuous stepping driving, and proposes several different sets of modified pulse sequences to realize continuous stepping driving using low-switching-rate pulse voltages. In the experiments, the motor showed continuous stepwise driving with a step width of about half of the electrode pitch. In addition, transient characteristics of charges on films were evaluated experimentally under the pulse driving condition, and contribution for thrust force enhancement was clarified.

Published: December 2018

Setelah jatuhnya rezim otoritarian, Pemerintah Indonesia mengehendaki adanya suatu praktik negara, dimana kekuasaan pemerintah dijalankan berdasarkan konstitusi Undang-Undang Dasar 1945 (UUD 1945). Sejalan dengan itu, konstitusi mengamanatkan pemerintah untuk menjaga keseimbangan keuangan negara sebagai salah satu upaya mewujudkan sistem pemerintahan yang transparan dan bertanggungjawab. Implikasinya, penerimaan negara menjadi salah satu aspek kunci dari kedaulatan negara dan oleh karena itu harusdiawasi secara ketat. Dalam rangka mengakomodasi mandat konstitusional tersebut. Pemerintah Indonesia membentuk Badan Pemeriksa Keuangan (BPK-RI) untuk menjadi garda terdepan dalam mengawal jalannya keuangan negara dan menutup kemungkinan terjadinya korupsi dan penyalahgunaan. Dalam rangka memperkuat peran BPK sebagai Supreme Audit Institution, maka kerja sama yang efektif dan profesional harus dilakukan oleh BPK dengan melibatkan Komisi Pemberantasan Korupsi (KPK-RI) dan Pusat Pelaporan dan Analisis Transaksi Keuangan. Pertanyaan yang hendak dijawab dalam penelitian ini adalah bagaimana formulasi kerja sama yang perlu diciptakan oleh BPK bersama KPK dan PPATKdalam rangka mewujudkan pengelolaan keuangan negara yang baik. Lebih jauh, penelitian ini akan menawarkan desain alternatif yang dapat mengasimilasikan tiga institusi tersebut dalam upaya pemberantasan kosupsi di Indonesia. Penelitian ini akan dipertajam dengan beberapa metode pendekatan, antara lain pendekatan konseptual, pendekatan perundang-undangan, dan pendekatan sejarah. Penulis berpendapat bahwa harus diciptakan suatu mekanisme kerja sama yang menempatkan laporan BPK sebagai basis pelaksanaan investigasi KPK. Selanjutnya, laporan hasil investigasi serta data intelejen PPATK terhadap transaksi mencurigakan yang melibatkan keuangan negara harus diposisikan sebagai kerangka acuan dalam memulai penyidikan KPK. Selanjutnya, BPK bersama KPK dan PPATK perlu menyusun kembali Memorandum of Understanding (MoU) perihal pemberantasan korupsi. Terakhir, independensi BPK secara organisasi, personal dan finansial perlu diperkuat untuk menunjang performa BPK dalam upaya penyelamatan keuangan negara.

The influence of ICT megatrends on global megatrends
Authors: Vukanović Zvezdan
Published: December 2018

In this paper, the author analyses the significant influence of IT on global megatrends. Of the five leading global megatrends, two are in the
field of ICT, digital media and new technologies. The main reasons for the impact of IT megatrends are twofold: (1) the digital convergence of the media, ICT and telecommunications industries, (2)the exponential increase in information, computing power and internet transfer data. Digital convergence will significantly contribute to changing business models. In an applicative sense, the author considers the concepts of Industry 4.0 - The Fourth Industrial Revolution (4IR), to be the most significant as it marks the paradigmatic change of information, the conceptual and processual transformation of data and services ecosystems
in the domains of robotics, the Internet of Things (IoT), Internet of Services, Automated Intelligence, Collaborative Robots (Cobots), Industrial Robots, Augmented Reality, and Virtual Reality. In business and strategic terms, digital media business models will transition, under the influence of digital convergence, to a multi-platform, complementary, interoperable and networked media and ICT ecosystem with a
specific focus on the production and distribution of media products, services and applications within the user interface, hypermedia, immersion, mass customization, personalized, augmented and ambient media
business space and environment.
From decentralization to re-centralization: Tendencies of regional policy and inequalities in Central and Eastern Europe
Authors: Loewen Bradley
Published: December 2018

The issue of decentralization in the postsocialist countries of Central and Eastern Europe (CEE) has faded from the research agenda since the democratic transition and EU accession. Conventionally presented as a global policy goal for supporting local democracy, improved governance and reduced regional inequalities, decentralization has been met with uncertain results in less developed regions. EU Regional Policy, initially supporting decentralization and related regionalization processes in CEE, has met challenges in lagging regions facing institutional legacies and capacity limitations. Perceived failures of decentralization point to a trend of re-centralization of regional policy in CEE countries, on the part of both national and EU levels, potentially exacerbating the trend of increasing regional polarization within countries. The cases of Estonia and Hungary illustrate these tendencies, drawing attention to national responses and the need for a continued dialogue on institutional development and EU Regional Policy reform in order to better target regional inequalities.
Authoritarian Neoliberalism: Its Ideological Antecedents and Policy Manifestations from Carl Schmitt’s Political Economy of Governance
Authors: Juego Bonn
Published: December 2018

The regime of authoritarian neoliberalism is underway. In contemporary political economy of governance, this regime has been construed as a crisis response of the capitalist class to manage the conflict-ridden consequences of economic globalization; and, as an ideological project of a section of the ruling elites to justify the embedding of market-oriented development processes in a politically repressive government institution. To contribute to recent scholarship attempts at defining the character and tendencies of this emergent regime, the article traces one of its key ideological antecedents from Carl Schmitt’s earlier formulation for a “strong state, free economy”. It then presents a survey of how this concept articulating the compatibility of authoritarianism and capitalism has manifested in related theories and actual policies since the long twentieth century – notably in: German ordoliberalism, Thatcherism and Reaganomics, the Kirkpatrick Doctrine and Political Development Theory, the Asian Values discourse, and the Effective State and Good Governance agendas. The governing authority in this regime can be called an authoritarian-neoliberal state.
