Influence of a multiaxial stress on the reversible and irreversible magnetic behaviour of a 3%Si-Fe alloy
Authors: Rekik Mahmoud , Hubert Olivier , Daniel Laurent
Published: December 2018

The research presented in this paper is motivated by the design of electrical devices submitted to mechanical stress. It aims at studying the magnetic behaviour of ferromagnetic materials submitted to biaxial stress. It deals with the evolution of the magnetic susceptibility, coercive field and magnetic losses with respect to stress, magnetic field level and frequency. These quantities are of primary importance in the design of rotors for high speed rotating machines.

The work is focused on the magnetic behaviour of a standard grade of Iron-Silicon alloy under the form of thin sheet. Non conventional experiments are performed on cross-shaped samples in order to apply biaxial stress representative of the loadings experienced by rotors of rotating machines. These experiments are performed on a multiaxial testing machine, ASTREE. The magnetic loading is applied using a single U-yoke. The measurement of magnetic induction, magnetic field and strain is conducted by the means of needle-B sensor, H-coil sensors and Digital Image Correlation (DIC) respectively. Both anhysteretic and dissipative responses to magneto-mechanical loadings are considered. The results allow to identify the more critical stress configurations for this material.

Authors: Nishimura Yoshihiro , Suzuki Takayuki , Fukuda Katsumi , Fukuta Masatoshi
Published: December 2018

Ultrasonic Systems are useful for inspecting ceramic materials because ultrasonic waves are easily propagated in such materials. Conventional ultrasonic testing (UT) methods cannot easily identify internal defects. This study built a visualization system for detecting and reconstructing internal defect images using probe array UT. Internal defect images were reconstructed by applying truncated singular value decomposition. We investigated how the sampling frequency and truncation index affect the reconstructed defect images.

Authors: Zhu Zhiwen , Zhang Wendi , Xu Jia
Published: December 2018

Stochastic bifurcation characteristics and optimal control of giant magnetostrictive film (GMF)-shape memory alloy (SMA) composite plate subjected to in-plane stochastic excitation were studied in this paper. Nonlinear difference item was introduced to interpret the hysteretic phenomena of both GMF and SMA, and then the nonlinear dynamic model of GMF-SMA composite plate subjected to in-plane stochastic excitation was developed. The stochastic stability of the system was analyzed, and the condition of stochastic Hopf bifurcation was discussed. The reliability function of the system was solved from backward Kolmogorov equation, and then the probability density of the first-passage time was obtained. Finally, the stochastic optimal control strategy was obtained in stochastic dynamic programming method. Numerical simulation shows that the stability of the trivial solution varies with bifurcation parameters, and stochastic Hopf bifurcation appears in the process; the reliability of the system is improved by stochastic optimal control, and the first-passage time is delayed. GMF-SMA composite plate combines the advantages of both GMF and SMA, and can reduce vibration through passive control and active control effectively. The results of this paper are helpful to application of GMF-SMA composite plate in engineering fields.

Authors: Luo Jinglin , Li Hao , Yan Guirong , Hu Junwen
Published: December 2018

In this paper, an electrodynamic vibration suppressor is proposed that can be used to suppress the main component of structural vibrations. This suppressor includes three main parts: an electrodynamic actuator, a power amplifier and a vibration controller. The intrinsic characteristics of the electrodynamic actuator were studied. After proposing a variable-step feedback harmonic cancellation algorithm, a controller was developed on the basis of this algorithm. To verify the effects of the suppressor, an experiment was conducted on a slender cylinder shell. The results show that the vibration was reduced by approximately 73%.

Authors: Ando Yoshinori , Baba Akira , Onuma Takuya , Murakami Iwanori , Yamada Kou
Published: December 2018

A magnetic gear can transmit a torque and a motion without the contact by the magnetic force. Today a magnetic gear are studied about increasing transmit torque and decreasing cogging torque. The property of the positioning is another significant property in use of a motion transmission by magnetic gears. Therefore it is important to measure the positioning property. The purpose of this research is to check the relationship between the number of the magnet of the gear and positioning property. Then we have developed three types of gear which have a different number of teeth severally. By using the developed three types of gear, the average and the standard deviation are calculated from experimental results. We reveal the influence of the number of the teeth to positioning property in several operation conditions.
Active control of honeycomb sandwich plate using MFC piezoelectric actuators
Authors: Zhang Chunlin , Zhang Xinong , Xu Minglong , Luo Yajun
Published: December 2018

This paper deals with the vibration control of a cantilever honeycomb sandwich plate by using Macro-Fiber Composite (MFC) piezoelectric actuator. Firstly, the honeycomb plate is equivalent to an orthogonal anisotropic plate. Secondly driving force and bending moment formulas of MFC actuator are derived based on the constitutive relations of the piezoelectric material, the equivalent parameters and bend deformation theory. The result reveals that driving force and bending moment not only depend on the driving voltage and piezoelectric strain constants (d33), but also have relationship with the elastic modulus of honeycomb plate. To simulate the vibration of cantilever honeycomb plate structure, the governing equation of the plate bonded with MFC actuators is derived. Finally, the vibration by proportional derivative (PD) control of system with MFC actuator is simulated. The results show that better control performance is obtained by using MFC actuator when system under impulse excitation and steady state sine excitation. The vibration amplitude is diminished over 75% under PD control.

Authors: Tu Jun , Kang Yihua , Wu Jianbo , Sun Yanhua
Published: December 2018

The problem of inability to calibrate due to uneven thickness in automatic ultrasonic testing used for the upset region of the drill pipe was studied. A water-immersion ultrasonic testing system was established to accomplish the inspection for this area and provide the defects information for post process. A real-time tracking method based on surface reconstruction was present to ensure all of the artificial defects to be accurately detected. An adjusting algorithm for the data was performed to update the detecting results, so that the fitted curve was favorable for calibration. A sample pipe with through-holes was test with the system. The experimental results showed that all of the artificial defects could be detected after surface reconstruction and the adjusted data could provide the basis for the quantification of flaw, all of which had proved the data adjusting algorithm to be effective.

Authors: Wang Cheng , Guan Wei , Gou Jin , Hou Feng , Bai Junqing , Yan Guirong
Published: December 2018

For free and random vibrations of weakly damped systems, a one-to-one relationship between vibration modal shapes of dynamic mechanical systems and linear compound matrix, and a one-to-one relationship between modal responses and principal components are demonstrated using the concept of modal coordinates. Based on this theoretical link, a novel time-domain structural system three-dimensional statistical operational modal analysis technique is proposed then. Numerical simulation processing results show that, the new PCA based method is insensitive to Gauss measurement noise, and enables to identify main contribution modal shapes and eigenfrequencies from the displacement response-only in despite of system boundary, load type, and load position.
Analysis of the eddy-current effect in the Hi-speed axial MFL testing for steel pipe
Authors: Wu Jianbo , Kang Yihua , Tu Jun , Sun Yanhua
Published: December 2018

According to the Lenz's Law, eddy-current essentially exists in MFL(magnetic flux leakage) testing due to the relative movement between steel pipe and excitation coil, apparently affecting the MFL signals with the testing speed rising. Hence, the constitutive equation of eddy-current in the steel pipe was established by using Lenz's Law and it was found that: eddy-current in the arriving zone has the different direction from excitation current, resulting in the reduction of magnetization intensity; but they have the same direction in the leaving zone, where the magnetization intensity is enhanced; and there is few eddy-current formed in the center; besides, the eddy-current density has direct proportion to the testing speed. Further, the effect on the MFL signal was investigated and it was shown that not only the magnitude but also the features are altered. Finally, a confirmation for the aforementioned analysis was conducted by numerical simulations.

Authors: Li Yong , Liu Xiangbiao , Chen Zhenmao , Zhao Hongda , Cai Wenlu
Published: December 2018

Multilayered Tubular Structures (MTS) such as pipeline are widely employed in such industrial fields as nuclear energy, petroleum, etc. It is vital to non-destructively evaluate MTS periodically before catastrophic accidents take place. As one of the advanced Electromagnetic Nondestructive Evaluation (ENDE) techniques, Pulsed Eddy Current Testing (PECT) has been found advantageous over the other ENDE methods regarding evaluation of integrity of MTS. In this paper, a fast forward model of PECT inspection of MTS is proposed based on the analytical modeling, namely the Extended Truncated Region Eigenfunction Expansion (ETREE). The closed-form expressions of PECT signals of 3D magnetic field and coil Electromotive Force (EMF) have been formulated. The proposed model has been verified by Finite Element Modeling (FEM) and experiments. The advantages of the model in terms of high computational speed and accuracy have been identified.

Published: December 2018

Since the excitement of gecko free-walk on a smooth surface is discovered with the cause of Wan der Waals force, researchers have focused on the development of biomimetic gecko tape. Hierarchical structure and anisotropic adhesion are two of the spotlights. However, little work has been done on integration of these two parameters. This paper presents a model design of orientated micro-and nano-arrays including three levels of setae, branches and spatulae. Finite element method is applied for compression shear test simulation. The anisotropic property is controllable due to the hierarchical surface design.
A large ratio data compression method for pipeline inspection based on EMAT-generated guided wave
Authors: Wei Zheng , Huang Songling , Zhao Wei , Wang Shen
Published: December 2018

In order to meet the engineering requirement of gas pipeline inline inspection for cracking defects, a new ultrasonic guided wave (GW) method based on electromagnetic acoustic transducer (EMAT) has emerged. In consideration of the large amount of original inspection data and the limited capacity of the storing device, the research on rapid and large ratio data compression is needed. This paper proposes a new large ratio data compression method based on subsection adaptive method (SAM) and wavelet neural network (WNN) algorithm. The influences of parameter selection on the compression quality, speed and ratio and the method of enhancing the compression speed of this method is studied. The experiment results indicate that compared with the traditional WWN compression algorithm, the proposed method has higher compression quality and speed, and a large compression ratio of 110:1 is achieved by the proposed method. It is thus suitable for gas pipeline crack inline inspection based on EMAT-generated GW.

Measuring system for volumetric strain measurement in hydrostatic pressure environment
Authors: Jing Zijian , Xu Minglong , Feng Bo
Published: December 2018

A measuring system is presented to improve the volumetric strain measurement in hydrostatic pressure environment for a hydro-compression loading test. The measuring system consists of a new triaxial extensometer, a novel contactless signal transmission system and an IPT (inductive power transfer) equipment. By the extensometer, triaxial deformations of foam specimen can be measured directly, from which the volumetric strain is determined. Sensitivities of the triaxial extensometer are predicted using a simplified analytical model, and verified through experimental calibrations. To avoid the punching and lead sealing techniques on the pressure chamber for hydro-compression loading and transfer the strain data of the triaxial extensometer effectively, a new modus of contactless differential signaling is developed in this paper for elimination of noise caused by the IPT.

Development of a flexible cross-wound eddy current array probe
Authors: Lepage Benoit
Published: December 2018

Cross-wound eddy current sensors have been used for years in the non-destructive testing industry for surface detection of cracks on steel components. The conventional sensor, which is a three dimensional transmit-receive structure comprising two orthogonal coils, can't be directly translated to a flat winding suitable for printed circuit board (PCB) manufacturing. This paper describes a method that makes it possible, through the use of finite element modeling (FEM), to reproduce the cross wound sensor response on a flexible printed circuit board. As a second step, an innovative compact PCB made cross-wound eddy current array (ECA) structure is presented and demonstrated experimentally.

Published: December 2018

An experimental study in ultrasonic propagation characteristics of a magnetic fluid under AC magnetic fields was conducted. Sound velocities in a magnetic fluid increased with elapsed time of the AC magnetic fields. Moreover, rapid decreases in sound velocities in a magnetic fluid were observed when the AC magnetic fields were stopped. These results were similar to those for DC magnetic fields. Dependence of frequencies and magnitudes of AC magnetic fields on sound velocities in a magnetic fluid was observed. Moreover, anisotropy was found in each frequency of the AC magnetic fields.

Authors: Murakami Iwanori , Imai Hiroshi , Ando Yoshinori , Yamada Kou
Published: December 2018

To date, the majority of artificial hearts have been nonpulsatile types. Natural hearts, however, are pulsatile, and the long-term biocompatibility of the nonpulsatile types has not been confirmed. We set out to develop a magnetic pump with a pulsatile flow. Because it is pulsatile, we were able to make this pump as small and compact as a natural heart. It consists of a motor, a bellows, and a permanent magnet. The pulsatile flow artificial heart relies on magnetic force. To determine the basic characteristics of the pump, we measured the flow, pressure and magnetic force. We describe the structure of the pump, it's manufacturing method, and it's principle of operation. The use of the bellows allows us to realize a structure where the fluid chambers and drive are separate. When the pump pulsated at 0.6 [Hz], the rate of flow was 0.618 [l/min]. The differential pressure between inflow and outflow was 3.5 [kPa]. The magnetic attractive force was 243.4 [N] and the magnetic repulsive force was 67.3 [N]. We confirmed that the pump was able to pump water by pulsating steadily.

Authors: Tsuchimi Daisuke , Sasaki Kana , Okuyama Takeshi , Tanaka Mami
Published: December 2018

A palpation is a useful method to detect cancer and to evaluate skin or under skin conditions. However, the palpation is a skillful method. Doctor's mental and physical conditions affect diagnoses by the palpation. Additionally, it is hard to share the feeling of palpation with other people because palpation is subjective skill. Therefore, the development of the sensor that can measure the skin and under skin condition of the body like softness as a doctor's palpation is demanded. In this paper, we focus on a haptic perception mechanism of human for evaluating the softness. Six objects are made to conduct sensory tests. The silicone rubber part of the objects has two kinds of thickness and three kinds of Young's modulus. Relationships between physical properties of evaluated objects and the softness that human feel in active touch are investigated. After that, to control the contact condition between objects and finger, a passive touch evaluation system is fabricated. Using the system, relationships between the stiffness of the objects and evaluated haptic softness are investigated under passive touch condition.

Authors: Jedryczka Cezary , Wojciechowski Rafal M. , Demenko Andrzej
Published: December 2018

The paper focuses on the analysis of the asynchronous torque of the line start permanent magnet synchronous motor (LSPMSM) with the asymmetrical squirrel cage winding. In order to calculate the asynchronous torque the parametrical field-circuit models of LSPMSM have been elaborated on. Further, the models have been applied to investigate the impact of squirrel cage asymmetry on the asynchronous torque. The evaluated asynchronous torque vs. rotor speed characteristic of proposed motor with asymmetrical cage has been compared with the characteristics of reference asynchronous motor and LSPMSM with symmetrical cage winding. It has been found that deepening of chosen bars of the cage improves the starting properties of the LSPMSM.

Authors: Rekanos I.T. , Tsiboukis T.D.
Published: December 2018

The application of the generalised radial basis functions neural networks to the solution of inverse problems in electromagnetism is investigated. A training strategy for the implementation of such networks is presented. The attractive property of these networks to work as universal approximators and the simplicity of their training process is examined in two application problems. In the first problem the evaluation of the conductivity profile of a layered planar structure is performed after the inversion of the impedance of a circular air cored probe coil, of rectangular cross section, which is placed above the considered structure. The second problem involves the introduction of the generalised radial basis functions to the estimation of geometrical parameters of inaccessible structures via a set of field or potential measurements. The results obtained from these applications illustrate the efficiency and accuracy of the estimation and generalisation abilities of the generalised radial basis functions networks.
Parallel genetic algorithm and its application to linear synchronous motor optimization
Authors: Lysenko L.I. , Omelyanenko V.I. , Sergeev S.A.
Published: December 2018

The problem of globally optimizing linear synchronous motor (LSM) design parameters in order to minimize power consumption is of great practical interest to those involved in engineering MAGLEV trains. The paper describes an optimization technique based on a Parallel Genetic Algorithm in which separate subpopulations of possible solutions in the search space are interpreted not as demes but as individuals with the subpopulation-points co-ordinate matrices identified as the individual chromosome sets. The second exclusive detail of the algorithm results from using a deformed polyhedron method as a means of improving the algorithm ability to fine-tune the solution. The subpopulation points are treated as polyhedron apices, after which search heuristics borrowed from the Nelder–Mead method are applied to polyhedrons to provide their adaptation. The developed algorithm was examined via a ten-dimensional multiextrema test function before being applied to the multicriteria problem of LSM optimization. In both cases, it has coped with the tasks quite successfully, and has improved on results reported earlier. The paper also explores the lower bound of a feasible domain in the LSM criteria space.

Published: December 2018

Permasalahan mengenai korupsi selalu menjadi berita utama di masyarakat. Besarnya dampak yang ditimbulkan, menjadikan korupsi harus segera dibenahi. Salah satu upaya yang dapat dilakukan adalah melalui pendidikan karakter dan penanaman nilai moral anti korupsi. Berbagai buku telah diterbitkan untuk meningkatkan pengetahuan dan kesadaran masyarakat melalui literasi. Namun sangat disayangkan, bahwa minat baca di Indonesia masih sangat rendah, yaitu 25, 1 %. Selaras dengan hal tersebut, teknologi augmented reality sangat potensial untuk dikembangkan dalam bentuk buku cerita anti korupsi. Hal tersebut dikarenakan fitur realita 3D dapat dimunculkan pada media 2D dimana memberikan kesan yang menambah ketertarikan dan minat pembaca. Dengan adanya aplikasi teknologi augmented reality diharapkan dapat meningktkan kualitas pendidikan, khususnya pada bidang anti-korupsi. Dari hasil pengujian black box yang dilakukan, aplikasi augmented reality ini dapat menjalankan fungsi-fungsinya sesuai yang diharapkan.

Authors: Pal Palash Kumar , Bhattacharjee Bharati , Ghosh Arnab Kumar , Chattopadhyay Aindrila , Bandyopadhyay Debasish
Published: December 2018

The current study aimed to demonstrate the potentially adverse effects of adrenaline, an endogenous stressor, on the melatonergic system, oxidative status, antioxidative responses and inflammatory markers in different parts of gastrointestinal tract of Wistar rat. These included stomach, duodenum and colon and they were incubated with different concentrations (2.5, 5.0 and 10.0 µg/mL) of adrenaline for 1h, respectively. The levels of melatonin, gene expressions of arylalkylamine N-acetyltransferase (AANAT) and melatonin receptor 1 (MT1) as well as other stress-induced parameters including NF-kB expression, levels of cAMP, calcium, malondialdehyde, protein carbonyl content, reduced glutathione, nitrate, superoxide dismutase, catalase, glutathione peroxidase and glutathione S-transferase, tumour necrosis factor-α, IL-1β, IL6 and IL10 were systemically measured in these tissues. An adrenaline dose-dependent decrease in level of melatonin, AANAT, MT1 and NF-kB in these tissues were observed. In contrast, the profound increases in the levels of cAMP, calcium and all oxidative stress markers, inflammatory cytokines (except IL10), and activities of antioxidant enzymes (except superoxide dismutase) were observed after adrenaline treatment. A maximum effect was found in tissues treated with 5 µg/mL of adrenaline. The Correlation studies between melatonin level and other parameters (any two at a time) indicated a potentially physiological interplay between adrenaline stress and melatonin tissue levels. Collectively, the results provided the novel data on the adverse effects of adrenaline on the endogenous melatonergic system, antioxidant and inflammatory responses in the gastrointestinal tissues of rats.

Leading places on the map: Opening up leadership practices in two Estonian peripheral places
Authors: Grootens Martiene
Published: December 2018

This paper sheds light on processes of place leadership that are enacted through visibility practices. While this strategy to “lead places on the map” has had some intended effects, such as increased tourism and lobby opportunities, this external orientation led to other consequences as well. First of all, it has led leadership to include a wider array of actors than the “traditional” place leaders that are bounded to a certain territory. Secondly, it points to the limitation of leadership in places that are in-between networks or “off the map”, thirdly, to the tension between a homogeneous outward image and the inherent heterogeneous nature of all places. Overall, this paper goes beyond a functionalistic understanding of place leadership and provides a more political understanding of how places are led. This contribution is based on fieldwork conducted on the Estonian island of Kihnu and the Estonian town of Järva-Jaani.
Integrating regional development and planning into “spatial planning” in Finland: The untapped potential of the Kainuu experiment
Authors: Purkarthofer Eva , Mattila Hanna Merikki
Published: December 2018

With Finland’s accession to the European Union in 1995, a regional level of administration responsible for regulation-based land-use planning and incentive-driven regional development policy was introduced. The administration of both policies on the same spatial scale and within the same organisation suggests increased coordination of spatial impacts and a move towards an integrated conception of spatial planning. In practice, however, the relationship of these two fields remains ambiguous. In the Finnish case, one potential explanation for this detachment lies in the de facto weakness of the regional scale. In the Kainuu region in Northeastern Finland, ambitions to strengthen the regional scale resulted in a self-government experiment between 2005 and 2012. This article addresses the implementation of this experiment, its implications for integrated regional governance and the lessons to be learned for the upcoming regional reform in Finland.
Introduction to the Special Issue: Territoriality and Governance in the Globalizing European Eastern Peripheries
Authors: Loewen Bradley , Raagmaa Garri
Published: December 2018

This special issue focuses on the governance of peripheries in CEE from a multiscalar perspective to identify current policy responses and practices at the European, regional, cross-border and local levels. We attempt to unite various paradigms of peripheries by taking a governance approach – paradigms that, when used independently, threaten to further fragment our understanding of non-core territories across CEE. The introductory paper progresses from discussing the territorial basis of peripheries, through rescaling processes and issues of governance, to the introduction of selected papers included in this issue.
Indicators for Public Sector Innovations: Theoretical Frameworks and Practical Applications
Authors: Kattel Rainer , Cepilovs Aleksandrs , Lember Veiko , Tõnurist Piret
Published: December 2018

The paper maps and analyzes all existing practical exercises aiming to develop indicators for public sector innovations. To our knowledge this is the first attempt to comprehensively gather information about various international efforts. We only considered such exercises where actual indicators were developed and used at least once. We map five such exercises through extensive desk research and 13 interviews with surveyed project members. The paper shows that all existing attempts to measure public sector innovations operate within a rather limited conception of the public sector (efficiency), neglecting other possible logics (e.g. legitimacy); the existing exercises also neglect large areas of public sector activities, e.g. cooperation with business and third sectors (such as service co-creation, public-private partnership practices). This narrow focus often dictates that indicators and their technical assumptions are copied from the private sector; none of the five analyzed exercises utilized public administration experience and research (e.g. on performance measurement). The paper argues that instead of trying to come up with quantified indicators, public sector innovations should be assessed in complex evaluation frameworks.
