La grammaire italienne de Lodewijk Meijer (1672)
Authors: Szoc Sara , Swiggers Pierre 
Published: September 2019

RésuméEn 1672 parut à Amsterdam, chez Abraham Wolfgang (1634–1694), une grammaire de l’italien rédigée en néerlandais. L’auteur de cette grammaire, publiée anonymement, peut être identifié comme Lodewijk Meijer (1629–1681). L’ouvrage, intituléItaliaansche Spraakkonst, se caractérise par une organisation méthodique très explicite, qui se reflète dans la structuration rigide et systématique de la matière, dans l’emploi conséquent d’une terminologie bilingue (latin–néerlandais), dans la description, fort parallèle, des classes de mots, et dans l’application rigoureuse du principe de conformité structurelle (analogiaen latin;gelijkvormigheidten néerlandais). Construite sur une théorie de grammaire générale, l’Italiaansche Spraakkonstest une grammaire particulière de l’italien qui, tout en étant basée sur des sources livresques, fournit une description très complète et didactiquement adéquate. Le noyau de la grammaire est constitué par la description des classes de mots: celles-ci sont définies et décrites selon leur nature, leur sous-classification (formelle et sémantique) et leurs possibilités de combinaison. La théorie des parties du discours dans l’Italiaansche Spraakkonstest organisée autour du nom et du verbe, les deux classes de mots par rapport auxquelles les autres classes sont définies. La présente étude s’ouvre par une mise en contexte historiographique de la grammaire italienne de L. Meijer. Ensuite, la démarche méthodologique et la terminologie déployées dans l’ouvrage sont au centre de l’analyse. L’examen de l’organisation de la matière grammaticale procède de l’articulation globale des classes de mots à l’étude de deux classes, à savoir l’article et l’adnomen(néerlandais:bynaam), ce dernier terme désignant chez Meijer l’ensemble des éléments adjectivaux. Le fait d’avoir érigé lesadnominaen une classe de mots autonome constitue un des apports les plus remarquables de ce grammairien, philosophe et ami de Spinoza (1632–1677), qui s’inscrit dans le courant du rationalisme post-cartésien.
Spotlights on the notion of lexical motivation across languages in the Western linguistic tradition, from the 16th century to the present
Authors: Urban Matthias 
Published: September 2019

SummaryThis article shows that an interest in differences and similarities in patterns of lexical motivation across languages has a long, if discontinuous, history in Western linguistic thought. The aim of the article is to trace this history by presenting examples that highlight the enduring fascination of authors from very different traditions with recurrent patterns of lexico-semantic associations. It also discusses the significance attributed to these patterns, which ranges from their practical value in etymological research to proving the psychic unity of mankind.
The transformation of African–Russian economic relations in the multipolar world-system
Authors: Gerőcs Tamás 
Published: September 2019

SUMMARY
Despite the historical legacy of the Soviet Union, the Russian Federation’s economic presence in Africa today is minuscule in comparison to that of the West or China. The aim of this Briefing is to provide a framework for the trajectory of African–Russian economic ties in the changing international environment. Although the economic, trade and investment affairs could develop more complementarity, it is still an open question whether African countries benefit from the deepening economic ties or whether these inhibit local socio-economic development.

The 2017 CCQM-K147 "Comparison of value-assigned CRMs for niacin (vitamin B3) in milk powder and infant formula matrices" is the first Key Comparison directly testing the chemical measurement services provided to customers by National Metrology Institutes (NMIs) and Designated Institutes (DIs) through certified reference materials (CRMs). CRMs certified for vitamin B3 (as niacin or niacinamide) content in milk powder and infant formula matrices were compared using measurements made on these materials under repeatability conditions. Five NMIs/DIs submitted seven CRMs certified for niacinamide and two CRMs certified for niacin. These materials represent most of the higher-order reference materials available in 2017 for this important nutrimental measurand.
Generalized Gauss Markov Regression (GGMR) and Bayesian methods were used to establish the Key Comparison Reference Function (KCRF) relating the CRM certified values to the repeatability measurements. The niacinamide and niacin results for all nine CRMs were deemed equivalent at the 95 % level of confidence and were used to define the KCRF for vitamin B3 (as niacinamide).
Monte Carlo methods and Bayesian methods were used to estimate 95 % level-of-confidence coverage intervals for the relative degrees of equivalence of materials, %d ± U95 (%d), and of the participating NMIs/DIs, %D ± U95 (%D). The Bayesian method estimates were selected as the final DoE values. For the niacinamide and niacin materials, all of the %D ± U95(%D) intervals, were within (-10 to 10) % of the consensus results and all of these are statistically equivalent. These results demonstrate that the participating institutions can value-assign CRMs for niacinamide and/or niacin in milk powder and infant formula matrices.

Published: September 2019

Abstract

Objective. Brain computer interfaces (BCIs) are slowly making their appearance on the consumer market, accompanied by a higher popularity among the general public. This new group of users requires easy-to-use headsets with robustness to non-precise placement. In this paper, an optimized fixed montage EEG headset for VEP BCIs is proposed. Approach. The proposed layout covers only the most relevant area with large sensors to account for slight misplacement. To obtain large sensors, without having them physically available, we tie multiple sensors together and simulate the effect by averaging the signal of multiple sensors. Main results. In simulations based on recorded 256-channel EEG data, it is shown that a circular center-surround configuration with sensor tying, leading to only eight channels covering a large part of the occipital lobe, can provide high performance and good robustness to misplacement. Automatically optimized layouts were unable to achieve better performance, demonstrating the utility of this manual design. Finally, the performance and benefits of sensor tying in the manual design are then validated in a physical experiment. Significance. The resulting proposed layout fulfills most requirements of an easy to use consumer EEG headset.

Published: September 2019

Abstract
In order to study the feasibility of electromagnetic ultrasonic method on the welding residual stress detection in Q345R plate, experiments and numerical simulations were carried out. The welding residual stress in the plate was firstly measured by electromagnetic acoustic transducer (EMAT). Then, finite element model of welding process was established to predict the residual stress in plate, who’s rationality was verified by blind hole experiment. At last, the average of numerical simulation results at five points along the plate’s thickness direction was compared with the electromagnetic ultrasonic measurement results. The results show that the residual stress measured by EMAT is consistent with those from numerical simulation in direction of the weld. However, in the vertical direction of the weld, the deviation between EMAT results and numerical simulation is relatively large near the weld fusion line. This phenomenon is also found in the junction between the heat affected zone and the base metal.

Abstract
Based on electrostatic micro-actuator, energy method is used to analyses its static and dynamic Pull-in mechanism. In addition, the model of electrostatic micro-actuator perforated-plate is used for example analysis to derive its dynamic Pull-in parameter without and with considering squeeze damping effect. By comparing the parameter values from MATLAB calculation and ANSYS simulation under the two circumstances mentioned above, the effects of damping ratio on Pull-in parameter can be obtained. The results show that, the dynamic Pull-in displacement is more than the static Pull-in displacement. And with the existence of squeeze damping effect, Pull-in voltage will increase. When the damping ratio reaches a certain extent, the dynamic Pull-in voltage value will be as large as the static Pull-in voltage value.

Published: September 2019

Abstract
Two port proportional slip-in cartridge valves are critical components of the heavy duty press hydraulic system. Their performance, especially the static flow rate under different valve opening size and the valve response time, is important to the press velocity control precision. So, it is necessary to build an accurate model of the valve to analyse different parameters’ influences on the valve performance. Based on the analysis of the valve structure and working principle, the valve model is established by the AMESim. The valve flow rate under different valve opening size ratio is calculated using the simulation model. The rated flow rate calculated by the simulation model is 0.33% less than the sample value, and the variation trend of the calculated flow rate curve is consistent with the manual curve. This demonstrates the considerable effectiveness of the valve simulation model. Then, the influences of the spring stiffness, the pilot oil pressure and the pilot valve gain on the valve poppet response time are analysed using the simulation model, respectively. This research may offer the basis for the whole hydraulic system building and control strategy designing.

Published: September 2019

Abstract
To meet the requirements of large metal tank weld inspection, a robot design scheme was proposed to walk on the outer surface of the tank and carry TOFD probe. The wall-climbing module, connecting frame module and TOFD weld inspection module are specifically designed. In this paper, the permanent magnetic adsorption principle and four-wheeled mechanism are both adopted in the wall-climbing module, meanwhile, the magnetic wheel’s adsorption force is analyzed under multiple parameters. The main parameters affecting the adsorption force are obtained. To ensure the minimum size and the lightest quality of magnetic wheel, the adsorption force is also optimized based on the main parameters which are related to the permanent magnet itself. The above work provides a reference value for the research and development of intelligent weld inspection products of large metal tanks.

Authors: Cai Chaozhi , Guo Lubin , Liu Jiachen , Wei Zhenyu 
Published: September 2019

Abstract
In this paper, the distributed parameter calculation model of the combustor of the high-speed and high-temperature heat-airflow test system is presented. The three-dimensional geometric model of combustor is established by using commercial software ANSYS 15.0, and the grids are divided. In order to understand the NO emission characteristics of the combustor of the high-speed and high-temperature heat-airflow test system, the combustion of fuel in the combustor is simulated by using the computational fluid dynamics simulation module of ANSYS 15.0. The simulation results show that the combustor produces the most thermodynamic NO near the theoretical oil-gas ratio, but less thermodynamic NO when the air is insufficient or excessive. Therefore, in order to effectively control the production of thermodynamic NO, it should be considered from lean or rich oil combustion.
Damage identification of wind turbine blade based on dynamic characteristics
Authors: Gu Yongqiang , Feng Jinfei , Jia Baohua 
Published: September 2019

Abstract
The wind turbine blade is an elongated structure composed of composite materials. Due to the harsh working environment and the vibration and deformation during operation, the blade is easily damaged, which seriously affects the smooth operation of the wind turbine, and has great potential safety hazards. The finite element software ANSYS is used to study the vibration characteristics under the condition of blade rotation, and different damage modal analysis can be carried out for different positions. The BP neural network is established by MATLAB to quantify the damage degree of the blade. The analysis results show that the damage and damage degree can be recognized by the change of natural frequency before and after the damage of the blade. The damage location can be identified by change rate of strain mode before and after the damage of the blade. The damage degree of the blade can be quantified and judged. The relative error rate is between -4.36% to 2.73%, and the recognition effect is more accurate.

Authors: Wu Hao , Zhang Fujun , Wang Zhengkai , Gao Hongli 
Published: September 2019

Abstract
Spark ignition is an important method to achieve combustion of in-cylinder mixture. The inductive charging ignition is considered to be a simple and effective ignition method. This study presents a circuit simulation model of this ignition system in MATLAB/Simulink and the effects of charging voltage, charging time and multi-pulse charging interval on ignition energy were calculated and the ignition energy value was obtained. The experimental study of the ignition system in a constant volume vessel was carried out to explore the influence of ignition energy on the initial combustion of kerosene. The results show that the simulation results match well with the experimental results. With the increase of ignition energy, the initial flame propagation of kerosene shows speed fluctuations and the higher ignition energy makes the propagation speed of flame fluctuate more obviously.

Authors: Geng Jiao , Liu Kang , Qi Hu , Wang Dongyan 
Published: September 2019

Abstract
In order to study the performance of the precast concrete slab with additional reinforcement at slab end, the vertical monotonic loading test was carried out on four double-span continuous slab specimens. By observing the failures and making a comparison between additional reinforcement end and extended reinforcement end in terms of stiffness and bearing capacity under vertical unidirectional loading, it can be concluded that the bearing capacity of the composite floor slab end with neither protruding rebars nor additional reinforcement is obviously lower, but the additional reinforcement at slab end could evidently enhance the bearing capacity and stiffness, even higher than that of slabs extending rebars into supports.
Application of high-order differential energy operator in bearing fault diagnosis
Authors: Xu Yuanbo , Cai Zongyan , Ding Kai 
Published: September 2019

Abstract
An alternative energy operator demodulation method named high-order differential energy operator is proposed in this paper. The high-order differential energy operator, unlike previous demodulation techniques, can detect the weak fault bearing signature from a heavily contaminated signal because it can increase the signal-to-noise ratio. Furthermore, this energy operator is also able to suppress vibration interferences. Thus, the operator is more robust than the classical Teager energy operator (TEO) and its improved versions (DESA-1 and DESA-2 for short). Besides, it is also a non-parameter and non-filtering method, so it is easy and straightforward to apply. Finally, the built-in amplitude demodulation (AD) capability eliminates the enveloping step required by most AD methods like TEO and Hilbert transform (HT). The results of simulation tests and bearing fault experiments demonstrate that this method can effectively extract fault features, certifying its superiority in comparison with previous demodulation methods. Therefore, it is more likely to be useful and practical in the field of bearing fault diagnosis, especially in the presence of intense noise and interferences.
Noise controlling by means of intensity of acoustic radiation measurements
Authors: Vodola Vincenzo 
Published: September 2019

Abstract
Noise control in working places often involves the design of acoustic treatment of enclosures and the design of proper devices able to reduce vibration of surfaces in machinery and structural borne propagation. However, in order to optimize the efficiency of the treatment, it would be very useful to properly relate the vibration with total sound emission. From a general point of view, it is quite important to determine the relation between vibration surfaces and total sound (or noise) emission. The same problem could be also studied for several other sources, such as loudspeakers or musical instruments. We employ the Intensity of Acoustic Radiation (IAR), a novel, corresponding parameter introduced recently, that relates modal analysis with sound production. This parameter is defined as the space-averaged amplitude of cross-spectrum between sound pressure caused by the movement of the vibrating surface and the velocity of the vibration of the surface itself. To measure IAR, an omnidirectional microphone is placed in a fixed position at a short distance over the surface, while an accelerometer is mounted at the same points utilized during modal analysis. IAR showing a very high correlation between Frequency Response Function (FRF) and sound production of the surfaces is, therefore, able to describe the relationship between vibration and noise emission.
