Authors: Zhang Guo , Wu Qingwei , Wang Taoyang , Zhao Ruishan , Deng Mingjun , Jiang Boyang , Li Xin , Wang Huabin , Zhu Yu , Li Fangting
Published: November 2018

The Gaofen-3 (GF-3) satellite is the first C-band multi-polarization synthetic aperture radar (SAR) with the ability of high-accuracy mapping in China. However, the Ground Control Points (GCPs) are essential to ensure the accuracy of mapping for GF-3 SAR imagery at present. In this paper, we analyze the error sources that affect the geometric processing and propose a new block adjustment method without GCPs for GF-3 SAR imagery. Firstly, the geometric calibration of GF-3 image is carried out. Secondly, the rational polynomial coefficient (RPC) model is directly generated after the geometric calibration parameters compensation of each image. Finally, we solve the orientation parameters of the GF-3 images through DEM assisted planar block adjustment and conduct ortho-rectification. With two different imaging modes of GF-3 satellite, which include the QPSI and FS2, we carry out the block adjustment without GCPs. Experimental results of testing areas including Wuhan city and Hubei province in China show that the geometric mosaic accuracy and the absolute positioning accuracy of the orthophoto are better than one pixel, which has laid a good foundation for the application of GF-3 image in global high-accuracy mapping.
Cutting Forces Measurement for Milling Process by Using Working Tables with Integrated PVDF Thin-Film Sensors
Authors: Luo Ming , Chong Zenghui , Liu Dongsheng
Published: November 2018

In the milling process, cutting forces contain key information about the machining process status in terms of workpiece quality and tool condition. On-line cutting force measurement is key for machining condition monitoring and machined surface quality assurance. This paper presents a novel instrumented working table with integrated polyvinylidene fluoride (PVDF) thin-film sensors, thus enabling the dynamic milling force measurement with compact structures. To achieve this, PVDF thin-film sensors are integrated into the working table to sense forces in different directions and the dedicated cutting force decoupling model is derived. A prototype instrumented working table is developed and validated. The validation demonstrates that profiles of the forces measured from the developed instrumented working table prototype and the dynamometer match well. Furthermore, the milling experiment results convey that the instrumented working table prototype could also identify the tool runout due to tool manufacturing or assembly errors, and the force signal spectrum analysis indicates that the developed working table can capture the tool passing frequency correctly, therefore, is suitable for the milling force measurement.

Published: November 2018

Since the 1970s, a great deal of attention has been paid to the development of semiconductor-based biosensors because of the numerous advantages they offer, including high sensitivity, faster response time, miniaturization, and low-cost manufacturing for quick biospecific analysis with reusable features. Commercial biosensors have become highly desirable in the fields of medicine, food, and environmental monitoring as well as military applications, whereas increasing concerns about food safety and health issues have resulted in the introduction of novel legislative standards for these sensors. Numerous devices have been developed for monitoring biological processes such as nucleic acid hybridization, protein–protein interaction, antigen–antibody bonds, and substrate–enzyme reactions, just to name a few. Since the 1980s, scientific interest moved to the development of semiconductor-based devices, which also include integrated front-end electronics, such as the extended-gate field-effect transistor (EGFET) biosensor, one of the first miniaturized chemical sensors. This work is intended to be a review of the state of the art focused on the development of biosensors and chemosensors based on extended-gate field-effect transistor within the field of bioanalytical applications, which will highlight the most recent research reported in the literature. Moreover, a comparison among the diverse EGFET devices will be presented, giving particular attention to the materials and technologies.

Published: November 2018

Ochratoxin A (OTA) has become one a focus of public concern because of its multiple toxic effects and widespread contamination. To monitor OTA in rice, a sensitive, selective, and one-step enzyme-linked immunosorbent assay (ELISA) using a nanobody-alkaline phosphatase fusion protein (Nb28-AP) was developed. The Nb28-AP was produced by auto-induction expression and retained an intact antigen-binding capacity and enzymatic activity. It exhibited high thermal stability and organic solvent tolerance. Under the optimal conditions, the developed assay for OTA could be finished in 20 min with a half maximal inhibitory concentration of 0.57 ng mL−1 and a limit of detection of 0.059 ng mL−1, which was 1.1 times and 2.7 times lower than that of the unfused Nb28-based ELISA. The Nb28-AP exhibited a low cross-reactivity (CR) with ochratoxin B (0.92%) and ochratoxin C (6.2%), and an ignorable CR (<0.10%) with other mycotoxins. The developed Nb-AP-based one-step ELISA was validated and compared with a liquid chromatography-tandem mass spectrometry method. The results show the reliability of Nb-AP-based one-step ELISA for the detection of OTA in rice.

Authors: Chang Yu-Hao , Liu Chien-Sheng , Cheng Chih-Chun
Published: November 2018

This study proposes a novel FSM compensation system for four degrees of freedom (DOF) laser errors compensation, which has the advantage of shorter optical path length, fewer elements and an easier set-up process, meaning that it can be used at different locations. A commercial software, Zemax, is used to evaluate the function of the proposed FSM compensation system and the mathematical modelling of the proposed FSM compensation system is established by using a skew-ray tracing method. Finally, the proposed FSM compensation system is then verified experimentally using a laboratory-built prototype and the result shows that the proposed FSM compensation system achieves the ability to compensate the 4 DOF of the laser source.
Motion Synchronous Composite Decoupling with Fewer Sensors on Multichannel Hydraulic Force Control for Aircraft Structural Loading Test System
Authors: Shang Yaoxing , Bai Ning , Jiao Lingzhi , Yao Nan , Wu Shuai , Jiao Zongxia
Published: November 2018

The aircraft full-scale fatigue test is widely used in the modern aircraft industry for the safety of flight. Generally, the aircraft full-scale fatigue test is achieved by structural loading; multiple hydraulic actuators are used to apply load for force control. The fatigue loading test takes approximately several years. A key challenge is how to accelerate the loading frequency to shorten the total test time. Nevertheless, when pluralities of hydraulic actuator simultaneously increase the loading frequency, the mutual coupling force from the low rigidity of the aircraft structure will cause a large loading error, meaning that the test cannot be implemented. Although it is possible to reduce error by adding sensors, the force sensors need to connect several kilometers of cable. This paper proposed a novel motion synchronous composite decoupling control strategy with fewer sensors. The control method compensates the negative coupling effect of the channels by integrating the command signals and feedback signals of all channels. It can suppress coupling force and reduce errors at higher frequencies, thereby shortening the experiment time. Opposed to traditional decoupling control methods, advantages of this strategy are that it only needs force sensors and it does not need additional displacement or velocity and acceleration sensors to collect state variables for building the state space. Furthermore, it has been experimentally verified that the new motion synchronous composite decoupling control method can indeed guarantee sufficient control accuracy when the test frequency is increased. The method has great economic significance for shortening test duration.

Published: November 2018

The Internet of Things (IoT) is by now very close to be realized, leading the world towards a new technological era where people’s lives and habits will be definitively revolutionized. Furthermore, the incoming 5G technology promises significant enhancements concerning the Quality of Service (QoS) in mobile communications. Having billions of devices simultaneously connected has opened new challenges about network management and data exchange rules that need to be tailored to the characteristics of the considered scenario. A large part of the IoT market is pointing to Low-Power Wide-Area Networks (LPWANs) representing the infrastructure for several applications having energy saving as a mandatory goal besides other aspects of QoS. In this context, we propose a low-power IoT-oriented file synchronization protocol that, by dynamically optimizing the amount of data to be transferred, limits the device level of interaction within the network, therefore extending the battery life. This protocol can be adopted with different Layer 2 technologies and provides energy savings at the IoT device level that can be exploited by different applications.
Scaling Effect of Fused ASTER-MODIS Land Surface Temperature in an Urban Environment
Authors: Liu Hua , Weng Qihao
Published: November 2018

There is limited research in land surface temperatures (LST) simulation using image fusion techniques, especially studies addressing the downscaling effect of LST image fusion. LST simulation and associated downscaling effect can potentially benefit the thermal studies requiring both high spatial and temporal resolutions. This study simulated LSTs based on observed Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Terra Moderate Resolution Imaging Spectroradiometer (MODIS) LST imagery with Spatial and Temporal Adaptive Reflectance Fusion Model, and investigated the downscaling effect of LST image fusion at 15, 30, 60, 90, 120, 250, 500, and 1000 m spatial resolutions. The study area partially covered the City of Los Angeles, California, USA, and surrounding areas. The reference images (observed ASTER and MODIS LST imagery) were acquired on 04/03/2007 and 07/01/2007, with simulated LSTs produced for 4/28/2007. Three image resampling methods (Cubic Convolution, Bilinear Interpolation, and Nearest Neighbor) were used during the downscaling and upscaling processes, and the resulting LST simulations were compared. Results indicated that the observed ASTER LST and simulated ASTER LST images (date 04/28/2007, spatial resolution 90 m) had high agreement in terms of spatial variations and basic statistics based on a comparison between the observed and simulated ASTER LST maps. Urban developed lands possessed higher LSTs with lighter tones and mountainous areas showed dark tones with lower LSTs. The Cubic Convolution and Bilinear Interpolation resampling methods yielded better results over Nearest Neighbor resampling method across the scales from 15 to 1000 m. The simulated LSTs with image fusion can be used as valuable inputs in heat related studies that require frequent LST measurements with fine spatial resolutions, e.g., seasonal movements of urban heat islands, monthly energy budget assessment, and temperature-driven epidemiology. The observation of scale-independency of the proposed image fusion method can facilitate with image selections of LST studies at various locations.
Employing Ray-Tracing and Least-Squares Support Vector Machines for Localisation
Authors: Chitambira Benny , Armour Simon , Wales Stephen , Beach Mark
Published: November 2018

This article evaluates the use of least-squares support vector machines, with ray-traced data, to solve the problem of localisation in multipath environments. The schemes discussed concern 2-D localisation, but could easily be extended to 3-D. It does not require NLOS identification and mitigation, hence, it can be applied in any environment. Some background details and a detailed experimental setup is provided. Comparisons with schemes that require NLOS identification and mitigation, from earlier work, are also presented. The results demonstrate that the direct localisation scheme using least-squares support vector machine (the Direct method) achieves superior outage to TDOA and TOA/AOA for NLOS environments. TDOA has better outage in LOS environments. TOA/AOA performs better for an accepted outage probability of 20 percent or greater but as the outage probability lowers, the Direct method becomes better.

Published: November 2018

We report on thermal and evanescent field sensing from a tellurium oxide optical microcavity resonator on a silicon photonics platform. The on-chip resonator structure is fabricated using silicon-photonics-compatible processing steps and consists of a silicon-on-insulator waveguide next to a circular trench that is coated in a tellurium oxide film. We characterize the device’s sensitivity by both changing the temperature and coating water over the chip and measuring the corresponding shift in the cavity resonance wavelength for different tellurium oxide film thicknesses. We obtain a thermal sensitivity of up to 47 pm/°C and a limit of detection of 2.2 × 10−3 RIU for a device with an evanescent field sensitivity of 10.6 nm/RIU. These results demonstrate a promising approach to integrating tellurium oxide and other novel microcavity materials into silicon microphotonic circuits for new sensing applications.

Authors: Corral-García Javier , González-Sánchez José-Luis , Pérez-Toledano Miguel-Ángel
Published: November 2018

The Internet of Things (IoT) is faced with challenges that require green solutions and energy-efficient paradigms. Architectures (such as ARM) have evolved significantly in recent years, with improvements to processor efficiency, essential for always-on devices, as a focal point. However, as far as software is concerned, few approaches analyse the advantages of writing efficient code when programming IoT devices. Therefore, this proposal aims to improve source code optimization to achieve better execution times. In addition, the importance of various techniques for writing efficient code for Raspberry Pi devices is analysed, with the objective of increasing execution speed. A complete set of tests have been developed exclusively for analysing and measuring the improvements achieved when applying each of these techniques. This will raise awareness of the significant impact the recommended techniques can have.

Authors: Lin Qijing , Zhao Na , Yao Kun , Jiang Zhuangde , Tian Bian , Shi Peng , Chen Feng
Published: November 2018

An ordinary optical fiber ultra-high temperature sensor based on infrared radiation with the advantages of simple structure and compact is presented. The sensing system consists of a detection fiber and a common transmission fiber. The detector fiber is formed by annealing a piece of ordinary fiber at high temperature twice, which changes the properties of the fiber and breaks the temperature limit of ordinary fiber. The transmission fiber is a bending insensitive optical fiber. A static calibration system was set up to determine the performance of the sensor and three heating experiments were carried out. The temperature response sensitivities were 0.010 dBm/K, 0.009 dBm/K and 0.010 dBm/K, respectively, which indicate that the sensor has good repeatability. The sensor can withstand a high temperature of 1823 K for 58 h with an error of less than 1%. The main reason why the developed ordinary optical fiber sensor can work steadily for a long time at high temperature is the formation of β-cristobalite, which is stable at high-temperature.

Cooperative Cyber-Physical Systems (Co-CPSs) can be enabled using wireless communication technologies, which in principle should address reliability and safety challenges. Safety for Co-CPS enabled by wireless communication technologies is a crucial aspect and requires new dedicated design approaches. In this paper, we provide an overview of five Co-CPS use cases, as introduced in our SafeCOP EU project, and analyze their safety design requirements. Next, we provide a comprehensive analysis of the main existing wireless communication technologies giving details about the protocols developed within particular standardization bodies. We also investigate to what extent they address the non-functional requirements in terms of safety, security and real time, in the different application domains of each use case. Finally, we discuss general recommendations about the use of different wireless communication technologies showing their potentials in the selected real-world use cases. The discussion is provided under consideration in the 5G standardization process within 3GPP, whose current efforts are inline to current gaps in wireless communications protocols for Co-CPSs including many future use cases.
Enhanced Accuracy of CMOS Smart Temperature Sensors by Nonlinear Curvature Correction
Authors: Lewis Gareth D. , Merken Patrick , Vandewal Marijke
Published: November 2018

In this paper, we demonstrate an improvement in the accuracy of a low-cost smart temperature sensor, by measurement of the nonlinear curvature correction at multiple temperature references. The sensors were positioned inside a climate chamber and connected outside to a micro-controller via a network cable. The chamber temperature was increased systematically over a wide range from −20 °C to 55 °C. A set of calibration curves was produced from the best fitting second-order polynomial curves for the offset in temperature between the sensor and reference. An improvement in accuracy of ±0.15 °C is with respect to the mentioned temperature range, compared to the significantly higher value reported of ±0.5 °C by the manufacturer for similar conditions. In summary, we demonstrate a significant improvement in the calibration of a low-cost, smart sensor frequently used in research and academic projects over a useful range of temperatures.
The Impacts of Cocoa Sustainability Initiatives in West Africa
Authors: Ingram Verina , Van Rijn Fedes , Waarts Yuca , Gilhuis Henk
Published: November 2018

To tackle the multiple challenges facing the cocoa sector, voluntary sustainability standards and corporate initiatives, largely focusing on farm and farmer group scale, are often implemented by public–private–civil society partnerships of stakeholders further in the value chain. This paper looks at the social, economic, and environmental effects of such initiatives, based on empirical evidence from large-scale, mixed-method studies using a suite of socioeconomic, agronomic, and environmental indicators to compare the situation of UTZ certified with non-certified farmers in 2012 and 2015 in Ghana, and 2013 and 2017 in Ivory Coast. The results show that, on average, outcomes are mixed and generally modest. However, significant cocoa productivity and income increases were experienced by certified farmers receiving a full package of services. However, the type and intensity of services has changed over time, decreasing for half of the farmers, and productivity and income increases are levelling off. These findings suggest that whilst partnerships have created new governance arrangements with an increased focus on sustainable value chains, initiatives which result in a living income and optimise productivity, whilst limiting environmental impacts, require sectoral transformation, continued partnerships, plus a range of other policy instruments to address the persistent, wicked problems in cocoa production.

Published: November 2018

Today, the casino industry generates various economic effects and is being developed as the major tourism solution that can overcome the limitations of the tourist industry. With the economic benefits from the growth of casino industry in the world economy, we are to implement the policies to facilitate the growth of the industry, therefore, the scale of the international casino industry is on the rise, but the competitiveness on the national level is getting intensified. In order to survive in casino industry, it is necessary to make efforts to establish an economically sustainable casino company. To this end, in-depth study of the financial value of the casino industry for its customers is required and these efforts are important to enhance the competitiveness of the casino industry. In this study, we have made a meaningful approach to apply the customer’s life value to the casino industry. CLV means the financial value obtained by converting the profit to be obtained for a certain period of time from the customers into the present value based on the discount rate. Thus, the purpose of this study was to develop a model and indicators that can be objectively evaluated by finding the life value factor of a customer suitable for the casino industry. As a result, we formed the five components of customers’ lifetime value assessment model, thereby laying the foundation for management of the customers’ specific strategies and customers’ care. Based on the results of the study, the foundation for the competitive advantage in the casino industry could be established as we could contribute to ensure the substantiality of the competitiveness in casino industry.
Funding Sustainable Cities: A Comparative Study of Sino-Singapore Tianjin Eco-City and Shenzhen International Low-Carbon City
Authors: Zhan Changjie , De Jong Martin , De Bruijn Hans
Published: November 2018

China has gone through a rapid process of urbanization, but this has come along with serious environmental problems. Therefore, it has started to develop various eco-cities, low-carbon cities, and other types of sustainable cities. The massive launch of these sustainable initiatives, as well as the higher cost of these projects, requires the Chinese government to invest large sums of money. What financial toolkits can be employed to fund this construction has become a critical issue. Against this backdrop, the authors have selected Sino-Singapore Tianjin Eco-city (SSTEC) and Shenzhen International Low-Carbon City (ILCC) and compared how they finance their construction. Both are thus far considered to be successful cases. The results show that the two cases differ from each other in two key aspects. First, ILCC has developed a model with less financial and other supports from the Chinese central government and foreign governments than SSTEC, and, hence, may be more valuable as a source of inspiration for other similar projects for which political support at the national level is not always available. Second, by issuing bonds in the international capital market, SSTEC singles itself out among various sustainable initiatives in China, while planning the village area as a whole and the metro plus property model are distinct practices in ILCC. In the end, the authors present a generic financing model that considers not only economic returns but also social and environmental impacts to facilitate future initiatives to finance in more structural ways.
The Spin-Off as an Instrument of Sustainable Development: Incentives for Creating an Academic USO
Authors: Vega-Gomez Francisco-Isidoro , Miranda F. Javier , Chamorro Mera Antonio , Pérez Mayo Jesús
Published: November 2018

In recent years, universities and public authorities have increasingly focused on creating USOs (university spin-offs) as a method of transferring research results to society and of achieving the sustainable development sought by European institutions. However, the success of these policies depends on the appeal of creating a USO for academics. The aim of this research was to examine the relative importance of certain factors that may boost academic entrepreneurship and, therefore, to guide public policies. To do this, a qualitative study was carried out among 42 researchers from Spanish universities and research centres to understand their motivations for creating a USO. A quantitative study was then carried out, based on Conjoint Analysis and with a sample of 1726 academics, to identify the relative importance of six conditions that influence their predisposition to become entrepreneurs. This technique is seldom used in the field of entrepreneurship and, to the best of our knowledge, has never been used before to analyse academic entrepreneurship. The results of the study show that personal economic benefit is clearly the factor that heightens the intention to create a USO the most. Research benefit, CV benefit, support programmes, teaching reduction and personal cost are of lesser importance. The study also concludes that there are few differences according to the academic’s profile.
An Introduction to the Hyperspace of Hargreaves-Samani Reference Evapotranspiration
Authors: Haie Naim , Pereira Rui M. , Yen Haw
Published: November 2018

Climate change has been shown to directly influence evapotranspiration, which is one of the crucial watershed processes. The common approach to its calculation is via mathematical equations, such as 1985 Hargreaves-Samani (HS85). It computes reference evapotranspiration (ETo) through three climatic variables and one constant: RA (extra-terrestrial radiation), TC (mean temperature), TR (temperature range) and KR (empirical coefficient). To make HS85 more accurate, one of its authors proposed an equation for KR as a function of TR in 2000 (HS00). Both models are 4D and their internal behaviours are difficult to understand, hence, the data driven applications prevalent among experts and managers. In this study, we introduce an innovative research by trying to respond to two questions. What are the relationships between TC and TR? What are the internal patterns of HS hyperspace (4D domain) and the changes in ETo possibilities of the two models? In the proposed approach, thresholds for the four variables are utilized to cover majority of the agroclimatic situations in the world and the hyperspace is discretized with more than 50,000 calculation nodes. The ETo results show that under various climatic conditions, the behaviour of HS is nonlinear (more for HS00) leading to an increased uncertainty particularly for data driven applications. TC and TR show patterns useful for regions with less data.
An Integrative View of Emotion and the Dedication-Constraint Model in the Case of Coffee Chain Retailers
Authors: Kim Daekil , Kim Byoungsoo
Published: November 2018

Following the phenomenal growth of and competition among coffee chain retailers, the coffee chain market has expanded substantially thanks to rising income levels, the increasing young population, and rapidly changing lifestyles. Attracting consumers’ attention and enhancing their loyalty behaviors has become very difficult for coffee chain retailers. This study seeks to understand the mechanisms through which emotions and the dedication-constraint model lead to brand loyalty and willingness to pay more to certain coffee chain retailers. Emotion responses and dedication-constraint model-based factors are major roles in the formation of loyalty behaviors, but few studies have combined them. To fill this knowledge gap, this study synthesizes emotional responses and the dedication-constraint model to develop a theoretical model. Based on the ambivalent view of emotions, it also examines how positive and negative emotions affect the combination of brand loyalty and willingness to pay more to certain coffee chain retailers. Moreover, it identifies the antecedents of affective and calculative commitments. Our findings indicate that affective commitment had significantly positive effects on positive emotion, brand loyalty, and willingness to pay more. It negatively affects negative emotion. Calculative commitment had significantly positive effects on positive emotion, brand loyalty, and willingness to pay more. However, contrary to our expectations, calculative commitment was positively related to negative emotions. Furthermore, service quality, quality of physical environment, and price fairness significantly affect affective commitments, while only price fairness significantly affects calculative commitments.

Authors: Zhang Mei
Published: November 2018

The aim of this paper is to examine systematically the intergenerational justice and solidarity on sustainability in China, which is fundamental for achieving social/cultural change, whereas this is threatened by environmental unsustainability. A questionnaire survey with a sample size of 752 was carried out in Nanjing, Yangtze River Delta, China, with different age groups, and in the meantime, a series of qualitative studies was carried out through in-depth interviews and focus groups. It is shown that: with increasing age, people are more concerned about general and large-scale sustainability issue, whereas for smaller scale and immediate sustainability issues, there is no clear tendency with increasing age; older generations are more concerned about the causes of climate changes; in terms of responsibility for environmental problems, there are statistically-significant view changes with increasing age; for priority considerations in sustainability, among age groups, at the personal level, there is generally no statistically-significant difference, whereas at the public level, there are some statistically-significant differences; for preserving the future, there is generally no statistically-significant difference among age groups. Overall, there are considerable differences in intergenerational justice on sustainability, although there are still indications of solidarity among generations.
Improving Water Use Efficiency under Deficit Irrigation in the Jordan Valley
Authors: Shammout Maisa’a W. , Qtaishat Tala , Rawabdeh Hala , Shatanawi Muhammad
Published: November 2018

The Jordan Valley is the prime irrigated agricultural area in Jordan which suffers shortage of water putting severe limitation on water allocation to farmers. To alleviate the problem, deficit irrigation was proposed for some vegetables such as bell pepper. Two field experiments in two growing seasons were conducted using bell pepper (Capsicum Annuum L.) to assess the effect of deficit irrigation on yield, water use efficiency (WUE), and water productivity (WP). The treatments were three irrigation levels: 100% (T1), 80% (T2), and 60% (T3) of the calculated crop evapotranspiration (ETc) using class A pan method. A cost–benefit analysis was carried out to determine the best economically suitable season for crop growth. The yields in both seasons were higher under T1, but there was no difference in WUE and WP between T1 and T2. The yield, WUE, and WP for T3 were significantly lower than for T1 and T2. Therefore, it is recommended to irrigate at 80% of ET. The best results were obtained for the total gross margin and the net present value in the winter season. Using deficit irrigation reduces water usage without significant yield loss, meanwhile maintaining relatively high WUE and supporting the sustainability of agriculture in the Jordan Valley.

Published: November 2018

Un nouveau gisement de ferritungstite est décrit ; ce minéral a été déterminé sur des échantillons de wolframite provenant du filon de la Bertrande, situé à une trentaine de kilomètres NE de Limoges et à deux kilomètres NNE de Saint-Sulpice-Laurière. La ferritungstite est, selon les auteurs, un tungstate de fer, un tungstate de fer et de calcium ou encore un tungstate de fer et d'aluminium. Des analyses effectuées sur le minéral de la Bertrande montre la présence de W, Fe, Ca, Al sur du matériel soigneusement trié. Mais l'analyse ponctuelle à la microsonde électronique montre seulement 1,4 % de CaO et absence d'Al₂O₃. La ferritungstite serait essentiellement un tungstate de fer hydraté, les autres éléments étant probablement dus à des impuretés.
MANAGEMENT APPROACHES FOR INDUSTRY 4.0 – THE ORGANIZATIONAL CULTURE PERSPECTIVE
Authors: Mohelska Hana , Sokolova Marcela
Published: November 2018

The Industry 4.0 concept describes a decentralized production chain that extends from design to the supply chain, production, distribution as well as customer service. Cyber Physical Systems (CPS) employ software and internet-connected machines that communicate in real-time to reduce error rates and increase efficiency. The basis is the co-operation of separate control units that are capable of autonomous decision-making, managing the assigned technological unit and in particular becoming an independent and full member of comprehensive production units. The Industry 4.0 concept requires continuous innovation and education that not only depends on the peoples’ skills but also on organizational culture. Appropriate managerial approaches play a vital role in the development of organizational culture. Most studies discuss technical aspects, but do not pay attention to managerial approaches and organizational culture, which are a major factor influencing the success of this concept. The aim of the paper is to examine the level of organizational culture in the Czech Republic and to seek appropriate managerial approaches for the development of organizational culture that can support the environment for innovation in the organization and therefore facilitate the entrepreneurship in the Industry 4.0 concept. A partial goal will be, among other things, to identify the implications of Industry 4.0 for human resources. In order to determine organizational culture in organizations, a large study was carried out in the form of a questionnaire survey − the Czech translation of Wallach᾽s Questionnaire (1983). According to the findings, the respondents perceive the organizational culture in the organizations under review is more bureaucratic and supportive than innovative. In their view the signs of innovative culture are not so striking. It is necessary to change managerial approaches to support innovative solutions.

Authors: Serra Wilson S. , Loureiro Marcelo
Published: November 2018

In this article we describe a new species of the annual fish genusAustrolebiasfrom the lower Uruguay river basin. The fusion of the urogenital papilla to the first anal fin ray in males and the pigmentation pattern, indicates a close relationship with the clade formed byA.bellottii,A.melanoorus, andA.univentripinnis. The new species can be differentiated from those by the following combination of characters: presence of well-defined light bands contrasting with the sides of the body, the distal portion of the anal fin dark gray, pelvic fins dark bluish green and bases united at about 50–80% on their medial margins, pectoral fins with iridescent blue sub-marginal band, and general coloration of body bluish green. The new species can only be found in wetlands of the Queguay river, an area included in the Uruguayan protected areas system and represents so far the only annual fish species endemic to the lower Uruguay river basin.
La lecture comme enfermement
Authors: Minzetanu Andrei
Published: November 2018

A partir d'une comparaison entre deux théories de la lecture - celle de Michel Charles et celle de Pierre Bayard -, et à partir de ce que la psychologie sociale appelle un "biais de confirmation", cet article essaie de comprendre la manière dont la lecture peut contribuer à une forme d'enfermement du lecteur, à un certain dogmatisme. Ce dernier est envisagé ici sous la forme de ce que l'épistémologie des vertus considère comme un "vice intellectuel". L'analyse repose sur un exemple concret, sur les pratiques de lecture de l'essayiste E. Cioran telles qu'on les retrouve dans ses Cahiers (1957-1972). Cet article s'inscrit dans une réflexion plus générale consacrée aux conditions de possibilité d'une lecture vertueuse.
Médiateurs ambidextres – Les deux sens de la traduction. L’exemple franco-tchèque de H. Jelínek (1878-1944)
Authors: Galmiche Xavier
Published: November 2018

Le champ de la traductologie, renouvelé de fond en comble au cours de ces dernières décennies, a parfois mis en avant les figures de traducteurs. Nous choisissons de nous intéresser à ceux que l’on peut appeler les « traducteurs ambidextres », c’est-à-dire traduisant de la « main droite » – d’une langue étrangère vers leur langue maternelle, et de la « main gauche » – dans l’autre sens. Pour explorer ce terrain mal défriché, nous nous limitons à une étude de cas et aux traductions du français en tchèque mais surtout du tchèque en français d’un traducteur particulier, H. Jelínek (1878-1944), qui fut l’un des « médiateurs culturels » les plus influents du XX e siècle entre la Bohême puis la Tchécoslovaquie et la France Bohême (il rassembla notamment la première anthologie en français de la « poésie tchèque moderne », parue en 1930). Pour comprendre les enjeux de son travail de traducteur ambidextre, nous recherchons quelques textes qui ont été traduits avant ou après lui et comparons les mérites des différentes versions.
Bachelard, philosophe du jour, philosophe de la nuit
Authors: Le Ru Véronique
Published: November 2018

L’œuvre de Bachelard se partage en une philosophie des sciences qui a fait date par son engagement rationaliste, et en une « métaphysique de l’imagination », expression qu’utilise Bachelard lui-même dans L’Air et les songes pour désigner le but avoué de l’ensemble des textes de poétique qu’il a produits. Notre propos est de mettre en évidence le caractère double de son œuvre, non pas dans une visée simplement descriptive, mais véritablement problématique : nous voudrions montrer que cette caractéristique s’explique par le principe du double qui travaille la réflexion de Bachelard à la racine à la fois dans son œuvre épistémologique et dans son œuvre de poétique.
Vermeer, Béatrice et le Guide : la peinture comme mystère littéraire
Authors: Edwards Paul
Published: November 2018

Cet article s’intéresse aux similarités entre deux tableaux : la Jeune Fille à la perle de Johannes Vermeer, et le Portrait de Béatrice Cenci par Guido Reni, dit le Guide (selon l’attribution du XIX e siècle). L’expression du visage semble indéterminée, et c’est à ce titre que ces œuvres peintes ont provoqué l’imagination littéraire ; Russell Hoban et Tracy Chevalier se sont penchés sur le premier tableau et le mystère de son expression, P.B. Shelley et Hawthorne sur le deuxième. Dans Le Faune de marbre , Hawthorne évoque le tableau du Guide pour écrire une théorie de l’art où la « suggestion » tient une part essentielle. Dans Les Cenci , Shelley met en scène Béatrice, et son visage devient l’objet de projections de la part de ses ennemis. Quel discours s’élabore lorsque le visage d’une femme devient signe ambivalent, écran où sont projetées l’innocence et la culpabilité, s’inscrivant contre la personne même et sa capacité à s’exprimer ?
Il est interdit de regarder : Marguerite au sabbat par Eugène Delacroix
Authors: Stead Evanghelia
Published: November 2018

Bien connues, les dix-sept lithographies conçues par Eugène Delacroix d’après le Faust de Goethe, insérées dans un livre imposant paru en 1828 sous la double enseigne du libraire Auguste Sautelet et de l’imprimeur-lithographe Charles Motte, constituent une série souvent analysée par les historiens de l’art dans la perspective de l’œuvre du peintre. En modifiant cette approche, l’article la considère sous l’angle de son support , le livre dans lequel elle a été insérée, et en relation avec ce qui l’entoure , le texte de la tragédie et les propos de Delacroix, en valorisant un faire de l’imagination , d’inspiration multiple et de facture inter-iconique. Grâce au collationnement d’une quinzaine d’exemplaires du livre, conservés dans les dépôts publics de plusieurs pays, on découvre en quoi la quinzième lithographie, l’apparition de Marguerite au sabbat, est exceptionnelle . L’interprétation proposée se fonde sur le rôle de l’ imagination dans ce Faust français, la pratique graphique de Delacroix, le passage afférent, et Le Voyage en Italie de Goethe. Quelques rectifications sur la manière usuelle de considérer cette œuvre sont apportées.
Thomas Clerc Pierre Huyghe. L’écrivain timekeeper en situation d’exposition
Authors: Villemur Frédérique
Published: November 2018

L’intervention de l’écrivain Thomas Clerc dans l’exposition de Pierre Huyghe au Centre Pompidou en 2013, conçue comme une performance revisitée de L’écrivain public (1995) de Huyghe, interroge le statut de l’auteur-performeur et celui de témoin doublé du statut de spectateur dans la personne de l’écrivain écrivant au cœur d’une exposition dont il fait lui-même partie. Nous interrogeons le déplacement de la fonction de l’écrivain public dans celui du traducteur de sensations et d’émotions propres à un lieu d’art, en situation d’immersion. Faut-il lire ce qui fait événement en un seul et même acte sous la plume de l’écrivain comme autant de traces venant inquiéter le réel dans un travail d’enquête sur le temps d’exposition ? Nous questionnons la fonction d’interprète et d’acteur d’une œuvre exposée à travers la figure de l’écrivain à l’œuvre.
Sur la bibliothèque de Rabelais
Authors: Pédeflous Olivier
Published: November 2018

Cet article se veut une contribution à la reconstitution de la bibliothèque de Rabelais, prenant en compte les travaux d’Abel Lefranc, Seymour de Ricci, Jean Porcher ou Romain Menini. Ce qu’il reste de cette bibliothèque n’excède pas 25 volumes, dont 1 incunable et 2 manuscrits. L’article propose d’ajouter 5 nouveaux titres aux listes classiques. Cette enquête confirme et accentue la prédominance des ouvrages grecs ou traduits du grec dans la collection de Rabelais. Bibliothèque de travail, malheureusement dispersée après sa mort dans des conditions inconnues, elle fut lentement patrimonialisée et devint objet de collection frénétique aux xixe et xxe siècles.
La bibliothèque du traducteur
Authors: Menini Romain
Published: November 2018

Pour connaître la bibliothèque de Jacques Amyot (1513-1593), nous disposons de l’inventaire qui fut réalisé après le décès de l’évêque. Cette liste, dont la plupart des exemplaires reste à identifier, n’est cependant pas suffisante pour se faire une idée exacte de la collection de livres qui fut celle du « sçavant translateur ». À cette fin, les annotations marginales portées par Amyot dans ses exemplaires de travail peuvent s’avérer extrêmement utiles. L’étude pose les bases d’une reconstitution de ce qui fut la bibliothèque de travail du grand traducteur de Plutarque.
Essai de théorisation de la pratique théâtrale en français langue étrangère : créativité artistique et apprentissage
Authors: Parisse Lydie
Published: November 2018

Le but de cet article est de présenter un atelier de pratique théâtrale mené à l’université avec des étudiants de français langue étrangère de niveau B2-C1. À partir de leurs journaux de bord, il s’agit d’observer comment se déroule le processus d’apprentissage, et ce qu’apporte la pratique du jeu. Nous constatons qu’il existe des similitudes entre deux processus : la créativité artistique d’une part, la démarche d’apprentissage d’autre part. Nous étudierons la logique négative telle que l’a théorisée Grotowski : elle consiste à se dépouiller de ses habitus, et à apprendre à désapprendre. Pour ce faire, nous établirons des parallèles avec les grands théoriciens du jeu de l’acteur.
Silence numérique et injonction de discours : vers un discours socio-affectif-cognitif intégratif en pratique d’une langue étrangère
Authors: Rémon Joséphine
Published: November 2018

À travers l’étude d’un corpus de productions écrites sur un forum d’enseignement à distance, nous mettons en lumière la tension entre injonction de discours et non-discours. Différents régimes donnent forme au positionnement dans cette dialectique : le régime du refus du non-discours, le régime du déni du non-discours, le régime de l’anticipation du non-discours. Au-delà de cette tension, nous voyons émerger un rapport apaisé au silence avec des contributions d’apprenants en ligne qui mêlent le socio-affectif et le cognitif.
Countable recognizability and residual properties of groups
Authors: de Giovanni Francesco , Trombetti Marco
Published: November 2018

A class of groups

\mathfrak X

is said to be countably recognizable if a group belongs to

\mathfrak X

whenever all its countable subgroups lie in

\mathfrak X

. It is proved here that the class of groups whose subgroups are closed in the profinite topology is countably recognizable. Moreover, countably detectable properties of the finite residual of a group are studied.
Algebraic cycles on a very special EPW sextic
Authors: Laterveer Robert
Published: November 2018

Motivated by the Beauville–Voisin conjecture about Chow rings of powers of

K3

surfaces, we consider a similar conjecture for Chow rings of powers of EPW sextics. We prove part of this conjecture for the very special EPW sextic studied by Donten-Bury et al. We also prove some other results concerning the Chow groups of this very special EPW sextic, and of certain related hyperkähler fourfolds.
