Published: September 2018

Photoelectric angle encoders, working as position sensors, have a great influence on the accuracy and stability of telescope control systems (TCS). In order to improve the tracking precision of TCS, a method based on subdivision error compensation for photoelectric angle encoders is proposed. First, a mathematical analysis of six types of subdivision errors (DC error, phase error, amplitude error, harmonic error, noise error, and quantization error) is presented, which is different from the previously used analysis based on the Lissajous figure method. In fact, we believe that a mathematical method is more efficient than the figure method for the expression of subdivision errors. Then, the distribution law and period length of each subdivision error are analyzed. Finally, an error compensation algorithm is presented. In a real TCS, the elevation jittering phenomenon occurs, which indicates that compensating for the amplitude error is necessary. A feed-forward loop is then introduced into the TCS, which is position loop- and velocity loop-closed, leading to a decrease of the tracking error by nearly 54.6%, from 2.31” to 1.05”, with a leading speed of 0.25°/s, and by 40.5%, from 3.01” to 1.79”, with a leading speed of 1°/s. This method can realize real-time compensation and improve the ability of TCS without any change of the hardware. In addition, independently of the environment and the kind of control strategy used, this method can also improve the tracking precision presumably because it compensates the measuring error inside the photoelectric angle encoder.

Published: September 2018

Lead-zirconate-titanate (PZT) nanoscale powder was first synthesized by the sol-gel method, then PZT and 0–3 type PZT/chrysotile fiber (CSF)/cement composite (PZTCC) wafers were fabricated after grind-mixing PZT powder with strontium carbonate and/or cement, ductile CSF in tandem with press-sintered process, respectively. The crystal structure (XRD), microstructure (SEM), piezoelectric properties after surface silver penetration, and polarization of the PZT and PZTCC wafer were investigated. Furthermore, self-sensing responses under either impulse or cyclic loading and micro-hardness toughness of PZTCC were also investigated. Results show that the incorporation of CSF and cement admixture weakens the perovskite crystalline peak of PZTCC; reduces the corresponding piezoelectric coefficient from 119.2 pC/N to 32.5 pC/N; but effectively bridges the gap on the toughness between PZTCC and concrete since the corresponding microhardness with 202.7 MPa of PZTCC is close to that of concrete. A good linear and fast electrical response against either impulse or cyclic loading of the PZTCC is achieved with their respective sensitivity, linearity, and repeatability to 1.505 mV/N, 2.42%, and 2.11%. The sensing responses and toughness of PZTCC is encouraging as an intrinsic piezoelectric sensor for real-time health monitoring of ductile concrete structures.
Efficient Interference Estimation with Accuracy Control for Data-Driven Resource Allocation in Cloud-RAN
Authors: Zhao Yanchao , Wu Jie , Li Wenzhong , Lu Sanglu
Published: September 2018

The emerging edge computing paradigm has given rise to a new promising mobile network architecture, which can address a number of challenges that the operators are facing while trying to support growing end user’s needs by shifting the computation from the base station to the edge cloud computing facilities. With such powerfully computational power, traditional unpractical resource allocation algorithms could be feasible. However, even with near optimal algorithms, the allocation result could still be far from optimal due to the inaccurate modeling of interference among sensor nodes. Such a dilemma calls for a measurement data-driven resource allocation to improve the total capacity. Meanwhile, the measurement process of inter-nodes’ interference could be tedious, time-consuming and have low accuracy, which further compromise the benefits brought by the edge computing paradigm. To this end, we propose a measurement-based estimation solution to obtain the interference efficiently and intelligently by dynamically controlling the measurement and estimation through an accuracy-driven model. Basically, the measurement cost is reduced through the link similarity model and the channel derivation model. Compared to the exhausting measurement method, it can significantly reduce the time cost to the linear order of the network size with guaranteed accuracy through measurement scheduling and the accuracy control process, which could also balance the tradeoff between accuracy and measurement overhead. Extensive experiments based on real data traces are conducted to show the efficiency of the proposed solutions.
MEMS Gyroscope Automatic Real-Time Mode-Matching Method Based on Phase-Shifted 45° Additional Force Demodulation
Authors: Bu Feng , Xu Dacheng , Zhao Heming , Fan Bo , Cheng Mengmeng
Published: September 2018

In order to solve the problem where existing mode-matching methods in microelectromechanical systems (MEMS) vibrating gyroscopes fail to meet real-time and reliability requirements, this paper presents a novel method to accomplish automatic and real-time mode-matching based on phase-shifted 45° additional force demodulation (45° AFD-RM). The phase-shifted 45° additional force signal has the same frequency as the quadrature force signal, but it is phase-shifted by 45° and applied to the sense mode. In addition, two-way phase-shifted 45° demodulations are used at the sense-mode detection output to obtain a phase metric that is independent of the Coriolis force and can reflect the mode-matching state. Then, this phase metric is used as a control variable to adaptively control the tuning voltage, so as to change the sense-mode frequency through the negative stiffness effect and ultimately achieve real-time mode-matching. Simulation and experimental results show that the proposed 45° AFD-RM method can achieve real-time matching. The mode frequency split is controlled within 0.1 Hz, and the gyroscope scale factor, zero-bias instability, and angle random walk are effectively improved.

Published: September 2018

We propose a novel tilted long period fiber grating (TLPFG) design, inscribed using a line-by-line inscription technique and an infrared femtosecond (Fs) laser. The responses of this TLPFG to external refractive index, temperature, torsion, and strain were systematically investigated to determine its sensing characteristics. The external refractive index (RI) was measured to be −602.86 nm/RIU at an RI of ~1.432. The TLPFG was used to accurately measure temperatures up to 450 °C with a sensitivity of 103.8 pm/°C. The torsion and strain sensitivity of the device were 48.94 nm/(rad/mm) and −0.63 pm/µε, respectively. These results demonstrate that the proposed TLPFG could be used as sensors in a series of application fields including high temperatures and external environments.

Our paper analyzes close collaboration between a manufacturer of domestic appliances and consumer electronics and its customers. It reflects on the inclusion of open innovation by users that is presented in the paper on the case of the development of the refrigerator door handle, with an emphasis on design and functionality. The main research question we wanted to answer was whether a buyer (customer/consumer) might actively participate in the process of a new product development. It was interesting to test it in a highly dynamic industry setup since white goods are becoming an integral part of consumers’ life style and not just a mere home appliances used for routine housekeeping tasks. Research sample includes 146 respondents. We applied the conjoint analysis and quality function deployment (QFD) in order to test and understand how customers perceive the different attributes of a new product development process.

Published: September 2018

Reasonable design of the overburden thickness of underground space (OTUS) can influence the outdoor thermal environment by affecting the ground plant communities. To optimize the design of the OTUS for improving the outdoor thermal environment, this study summarized the influence mechanism of the OTUS on the outdoor thermal environment and proposed a framework of the optimization design of underground space overburden thickness. A typical row layout residential area in Nanjing, China, was taken as the research object on which to perform a numerical study of the influence of plant communities formed by two types of plant collocations (a middle- and low-level plant collocation and a middle- and high-level plant collocation) on the outdoor thermal environment (airflow field, air temperature, relative humidity and thermal comfort) under three different ratios of trees to shrubs (2:3, 1:2, and 1:3), and to provide suggestions regarding the design of the OTUS according to the designer’s requirements. The conclusions were summarized as follows: (1) If a designer wants to enhance outdoor ventilation, the OTUS should be designed to satisfy the requirements for the middle- and low-level plant collocations and the overburden thickness of the 2/5 underground space development area should be set to 80~100 cm, the overburden thickness of the other 2/5 area should be set to 45~60 cm and the overburden thickness of the remaining 1/5 area should be set to 30~45 cm. (2) If a designer wants to reduce air temperature, increase relative humidity, and improve outdoor thermal comfort, the OTUS should be designed to satisfy the requirements for middle- and high-level plant collocations and the overburden thickness of the 1/4 underground space development area should be set to 80~100 cm, and the overburden thickness of the remaining 3/4 area should be set to 45~60 cm.
Intersection Traffic Prediction Using Decision Tree Models
Authors: Alajali Walaa , Zhou Wei , Wen Sheng , Wang Yu
Published: September 2018

Traffic prediction is a critical task for intelligent transportation systems (ITS). Prediction at intersections is challenging as it involves various participants, such as vehicles, cyclists, and pedestrians. In this paper, we propose a novel approach for the accurate intersection traffic prediction by introducing extra data sources other than road traffic volume data into the prediction model. In particular, we take advantage of the data collected from the reports of road accidents and roadworks happening near the intersections. In addition, we investigate two types of learning schemes, namely batch learning and online learning. Three popular ensemble decision tree models are used in the batch learning scheme, including Gradient Boosting Regression Trees (GBRT), Random Forest (RF) and Extreme Gradient Boosting Trees (XGBoost), while the Fast Incremental Model Trees with Drift Detection (FIMT-DD) model is adopted for the online learning scheme. The proposed approach is evaluated using public data sets released by the Victorian Government of Australia. The results indicate that the accuracy of intersection traffic prediction can be improved by incorporating nearby accidents and roadworks information.
Capsid Structure of dsRNA Fungal Viruses

Published: September 2018

Most fungal, double-stranded (ds) RNA viruses lack an extracellular life cycle stage and are transmitted by cytoplasmic interchange. dsRNA mycovirus capsids are based on a 120-subunit T = 1 capsid, with a dimer as the asymmetric unit. These capsids, which remain structurally undisturbed throughout the viral cycle, nevertheless, are dynamic particles involved in the organization of the viral genome and the viral polymerase necessary for RNA synthesis. The atomic structure of the T = 1 capsids of four mycoviruses was resolved: the L-A virus of Saccharomyces cerevisiae (ScV-L-A), Penicillium chrysogenum virus (PcV), Penicillium stoloniferum virus F (PsV-F), and Rosellinia necatrix quadrivirus 1 (RnQV1). These capsids show structural variations of the same framework, with 60 asymmetric or symmetric homodimers for ScV-L-A and PsV-F, respectively, monomers with a duplicated similar domain for PcV, and heterodimers of two different proteins for RnQV1. Mycovirus capsid proteins (CP) share a conserved α-helical domain, although the latter may carry different peptides inserted at preferential hotspots. Insertions in the CP outer surface are likely associated with enzymatic activities. Within the capsid, fungal dsRNA viruses show a low degree of genome compaction compared to reoviruses, and contain one to two copies of the RNA-polymerase complex per virion.
Land Use and Land Cover Changes and Their Effect on the Flow Regime in the Upstream Dong Nai River Basin, Vietnam
Authors: Truong Nguyen Cung Que , Nguyen Hong Quan , Kondoh Akihiko
Published: September 2018

The upstream Dong Nai River Basin is located in the country’s key economic development region and its water resources are a key component of sustainable regional development. The objective of this study was to assess the impact of land use and land cover changes (LULCC) on the flow regime in this tropical forest basin using a flow–duration curve analysis that has been widely used in Japan. This study combined two different temporal and spatial scales of satellite data, Landsat and Global Inventory Modeling, and Mapping Studies (GIMMS) normalized difference vegetation index (NDVI) to analyze LUCC. Results from the land cover classification of five Landsat images between 1973 and 2014 indicated that the forest area decreased significantly in the period of 1994 to 2005 due to population growth, leading to land conversion for agriculture. Furthermore, secular changes in the annual GIMMS-NDVI data revealed that land cover changes occurred from 1996 and a large amount of forest was lost in 1999; however, due to the rapid regrowth of secondary forest of tropical forests and the development of the crop, the vegetation recovered shortly afterwards in 2000 before decreasing again after 2004. Following large-scale deforestation, the total discharge, maximum flow, and the plentiful, ordinary, low, and small-scale runoff increased sharply and decreased thereafter because of vegetation regrowth.

The efforts to improve the stability of membrane filtration in applications for wastewater treatment or the purification of drinking water still dominate the research in the field of membrane technology. Various factors that cause membrane fouling have been explored to find the solution for improving the stability of the filtration and prolong membrane lifetime. The present work explains the filtration performance of a hollow fiber membrane that is fabricated from polyethersulfone-2-(methacryloyloxy) ethyl phosphorylchloline while using a sodium alginate (SA) feed solution. The filtration process is designed in a pressure driven cross-flow module using a single piece hollow fiber membrane in a flow of outside-inside We investigate the effect of Ca and Mg ions in SA solution on the relative permeability, membrane resistance, cake resistance, and cake formation on the membrane surface. Furthermore, the performance of membrane filtration is predicted while using mathematical models that were developed based on Darcy’s law. Results show that the presence of Ca ions in SA solution has the most prominent effect on the formation of a cake layer. The formed cake layer has a significant effect in lowering relative permeability. The developed models have a good fit with the experimental data for pure water filtration with R2 values between 0.9200 and 0.9999. When treating SA solutions, the developed models fit well with experimental with the best model (Model I) shows R2 of 0.9998, 0.9999, and 0.9994 for SA, SA + Ca, and SA + Mg feeds, respectively.

This study presents three new hybrid artificial intelligence optimization models—namely, adaptive neuro-fuzzy inference system (ANFIS) with cultural (ANFIS-CA), bees (ANFIS-BA), and invasive weed optimization (ANFIS-IWO) algorithms—for flood susceptibility mapping (FSM) in the Haraz watershed, Iran. Ten continuous and categorical flood conditioning factors were chosen based on the 201 flood locations, including topographic wetness index (TWI), river density, stream power index (SPI), curvature, distance from river, lithology, elevation, ground slope, land use, and rainfall. The step-wise weight assessment ratio analysis (SWARA) model was adopted for the assessment of relationship between flood locations and conditioning factors. The ANFIS model, based on SWARA weights, was employed for providing FSMs with three optimization models to enhance the accuracy of prediction. To evaluate the model performance and prediction capability, root-mean-square error (RMSE) and receiver operating characteristic (ROC) curve (area under the ROC (AUROC)) were used. Results showed that ANFIS-IWO with lower RMSE (0.359) had a better performance, while ANFIS-BA with higher AUROC (94.4%) showed a better prediction capability, followed by ANFIS0-IWO (0.939) and ANFIS-CA (0.921). These models can be suggested for FSM in similar climatic and physiographic areas for developing measures to mitigate flood damages and to sustainably manage floodplains.

Published: September 2018

Instream ecological flow is an essential determinant of river health. Intra- and interannual distribution characteristics of runoff have been altered to different degrees by dam construction. Historical runoff series with alterations, as basic data for ecological flow calculation, provide minimal instream hydrological process information, which affects the credibility of calculation results. Considering the influence of the alterations in runoff series on ecological flow calculation, the Gini coefficient (GI) is introduced to study the evenness degrees of the intra-annual runoff distribution of four hydrological stations located in the Naolihe basin of the Sanjiang Plain. The hydrological alteration diagnosis system is used to examine the alteration points in the GI series of each hydrological station for selecting reasonable subsequences. Based on the selected subsequences, the ecological flow of each station is calculated using three hydrological methods, and the comprehensive ecological flow is calculated using weighted calculation results from the three hydrological methods. The study results show that ecological flow and natural flow have similar processes with two peaks occurring in the process in May and August, respectively. Also, dams decrease the ecological water requirement damage frequency in dry seasons, but overuse of water resources increases the ecological water requirement damage frequency in flood seasons.

Published: September 2018

The analysis of molecular states of individual cells, as defined by their mRNA expression profiles and protein composition, has gained widespread interest in studying biological phenomena ranging from embryonic development to homeostatic tissue function and genesis and evolution of
cancers. Although the molecular content of individual cells in a tissue can vary widely, their molecular states tend to be constrained within a transcriptional landscape partly described by the canonical archetypes of a population of cells. In this study, we sought to characterize the effects
of an acute (partial hepatectomy) and chronic (alcohol consumption) perturbation on the molecular states of individual hepatocytes during the onset and progression of liver regeneration. We analyzed the expression of 84 genes across 233 individual hepatocytes acquired using laser capture microdissection.
Analysis of the single-cell data revealed that hepatocyte molecular states can be considered as distributed across a set of four states irrespective of perturbation, with the proportions of hepatocytes in these states being dependent on the perturbation. In addition to the quiescent, primed,
and replicating hepatocytes, we identified a fourth molecular state lying between the primed and replicating subpopulations. Comparison of the proportions of hepatocytes from each experimental condition in these four molecular states suggested that, in addition to aberrant priming, a slower
transition from primed to replication state could contribute toward ethanol-mediated suppression of liver regenerative response to partial hepatectomy.
Two species of Caiusa Surcouf (Diptera: Calliphoridae) new to India, with data on larval behaviour and morphology
Authors: Banerjee Ananda , Rognes Knut , Whitmore Daniel
Published: September 2018

Caiusa Surcouf (Diptera: Calliphoridae) is an Old World genus of blow flies, the larvae of which feed on egg masses in the foam nests of various species of rhacophorid tree frogs. Here, we provide the first records for India (West Bengal, Eastern India) of Caiusa coomani Séguy, 1948 and C. karrakerae Rognes, 2015, together with new information on the behaviour and morphology of their larvae. Active surface swimming to disperse from infested nests is documented in blow fly larvae for the first time, as is the presence of a large internal air sac presumably acting as a floating aid. Chiromantis simus (Annandale, 1915) (Anura: Rhacophoridae) egg masses are first recorded as a feeding substrate of Caiusa larvae.
La victoire aujourd’hui, de l'évanescence au dépassement
Authors: Brustlein Corentin
Published: September 2018

La victoire est une notion plus compliquée à définir qu’il n’y paraît. Elle suppose l’atteinte d’objectifs militaires et politiques, mais aussi la perception et l’acceptation d’une nouvelle réalité par l’adversaire. Les guerres asymétriques du début du XXI e siècle – de l’Afghanistan à l’Irak en passant par le Sahel – montrent que la supériorité militaire ne garantit pas la victoire. Il ne faut pas en conclure que l’emploi de la force armée serait nécessairement vain.
Conflits d’Afrique subsaharienne : l’éternel retour ?

Au Sahel, au Soudan du Sud, dans l’Afrique des Grands Lacs, les conflits récurrents témoignent surtout de l’échec des gouvernances héritées de la colonisation. Les pouvoirs politiques n’ont jamais reflété la diversité des communautés de leurs sociétés. La démocratisation des années 1990 ne pouvait dans ces conditions qu’être un trompe-l’œil. Les oligarchies tournent à la prédation de plus en plus violente, et tous les éléments semblent réunis pour que les conflits perdurent.

Published: September 2018

Faute de pouvoir accéder à des zones de guerre, nombre de chercheurs étudient les mouvements insurrectionnels ou terroristes à travers le prisme des vidéos de propagande. L’exemple de Boko Haram illustre les limites d’une telle méthode qui méconnaît les réalités du terrain et accorde trop de poids aux arguments de nature religieuse. La propagande veut donner à croire qu’il existe une Internationale djihadiste. Les dynamiques sociologiques à l’œuvre au Nigeria invitent à nuancer une telle vision.

Published: September 2018

Les landsmanshaftn ou sociétés de secours mutuels, œuvrèrent à l’intégration économique et culturelle des juifs polonais en France, de la fin du 19 e  siècle aux lendemains de la Seconde Guerre mondiale. Après la Shoah, elles deviennent également des réceptacles privilégiés des expériences traumatiques de leurs membres survivants ou nouvellement arrivés de Pologne. Pourtant, elles sont encore peu étudiées comme sources pour l’histoire de la Shoah alors même qu’elles disparaissent depuis les années 1980. L’article explore les possibilités de retrouver le « monde disparu » de ces riches relations de sociabilité et des mémoires de la Shoah qui se sont élaborées au sein de ces landsmanschaftn après la guerre, malgré des sources peu nombreuses et très dispersées.
Les écrits intimes des responsables nazis
Authors: Patin Nicolas
Published: September 2018

Que peuvent nous apprendre les journaux intimes des responsables nazis ? Au-delà de ce qu’ils révèlent du for intérieur, ils dessinent une certaine lecture des événements historiques, de la prise du pouvoir à la dictature national-socialiste. En creux, ces sources disent également quelque chose de la Shoah : alors qu’ils ne l’évoquent que très rarement directement, ils montrent, pour les membres de la génération du front de 1914-1918, un recouvrement des crimes de 1939-1945 par les catégories d’analyse antérieures, les journaux servant alors, dans leur continuité, de ressort intime d’automystification. Pour les membres de la génération suivante, l’écriture intime fonctionne comme un outil permettant d’écrire la grande chronique d’une période perçue comme épique.
Que savait-on du sort des juifs déportés au sein de la police française ?
Authors: Joly Laurent
Published: September 2018

Qu’imaginaient et que savaient les policiers français du sort des juifs qu’ils arrêtaient et livraient aux nazis sous l’Occupation ? Un témoignage exceptionnel, rédigé par un sous-officier des Renseignements généraux à Paris, Louis Sadosky, révèle que dès avril 1942, lors d’un séjour à Berlin, ce policier fut informé du projet de Hitler de « destruction complète et à jamais » de l’ensemble des juifs européens. Sadosky savait. Pourtant, une fois de retour à Paris, il semble avoir occulté cette information. Jusqu’à la Libération, il traque impitoyablement les juifs de la capitale. Quant à ses collègues, la plupart ont conscience que la déportation est un voyage sans retour. Ils savent que la mort est probablement au bout.

Dans la République fédérale d’Allemagne, les anciens policiers de carrière de la Gestapo ont tenté de refaire carrière dans les administrations publiques en faisant valoir leurs droits de fonctionnaires. Les requêtes individuelles adressées au ministère fédéral de l’Intérieur sont toutefois déboutées en raison de la qualification de la Gestapo comme organisation criminelle par le Tribunal militaire international de Nuremberg en 1946. L’article présente les sources administratives de ce contentieux pour les années 1950 en montrant qu’il s’agit d’un lieu d’élaboration, parmi d’autres, d’un discours de distanciation et de disculpation face aux crimes commis par les policiers du régime nazi.
¿Para qué sirve la enseñanza de la historia? Perspectivas de docentes y estudiantes británicos
Authors: Chapman Arthur , Burn Katharine , Kitson Alison
Published: September 2018

Se sabe relativamente poco acerca de las ideas de los maestros en formación sobre la naturaleza y el propósito de la enseñanza de la historia. Este artículo revisa la investigación sobre este tema y presenta un análisis de cómo el currículum nacional inglés ha conceptualizado los objetivos de la enseñanza de la historia desde el año 1991. Los datos derivados de una discusión en línea permiten explorar el pensamiento de 40 docentes de historia en prácticas y analizarlos cualitativamente para conocer la variedad de ideas presentes en esta muestra. Los estudiantes tuvieron una amplia gama de puntos de vista sobre los objetivos y propósitos de la enseñanza de la historia y se identificaron las divergencias y convergencias entre el pensamiento de los estudiantes y el pensamiento de los políticos ingleses y de los líderes de opinión. Se concluye que quienes desarrollan los currículos deben prestar mucha más atención que en el pasado al pensamiento de los actuales y futuros profesores de historia, que son en último término los responsables del diseño de las propuestas curriculares.

La pertinencia del concepto de histéresis en las disciplinas humanistas
Authors: Martínez-Val Juan , Arroyo-Almaraz Isidoro , García-García Francisco
Published: September 2018

Se estudia la conveniencia de incluir el concepto de histéresis en las disciplinas humanistas, así como la necesidad de incorporar el análisis de los fenómenos donde aquél participa. La histéresis se produce en los más diversos campos de la acción y el pensamiento humanos, y su estudio contribuiría a completar y perfeccionar la visión que tenemos de los mismos. Al realizar la inclusión que aquí se propone, se operan varios cambios de orden epistemológico, operativo y conceptual. En las disciplinas humanistas, los conceptos vienen asumiendo por tradición el papel de herramientas analíticas en bastante mayor medida que el de contenidos sobre los que efectuar el análisis. La histéresis manifiesta su alcance como hecho a analizar y también como herramienta de análisis, pero en el caso presente hemos tenido en cuenta más aspectos del segundo enfoque que del primero. De aquí que nos hayamos centrado en ubicar su campo epistemológico.

En este artículo llevamos a cabo una extensa revisión de la literatura científica en lo relativo a los vínculos entre materialismo y felicidad, desde un enfoque multidisciplinar que incluye la psicología, la comunicación, la economía y la ética. La línea dominante en la bibliografía insiste en vincular un mayor materialismo con una menor auto-percepción de felicidad y de bienestar, y con una mayor propensión a la depresión. En esta revisión atendemos a los aspectos que así lo evidencian, al rumbo actual de las investigaciones y a los retos aún pendientes de clarificación por parte de la comunidad investigadora.
Regímenes de movilidad y expropiación del tiempo: la espera como cronopolítica
Authors: Abad Miguélez Begoña
Published: September 2018

La gestión de la movilidad/circulación de la población es una cuestión de biopolítica que implica la producción jerárquica y desigual de las condiciones de dicha movilidad. En esta distribución desigual no solo se ordenan los espacios sino también los tiempos, ritmo y velocidad, de ahí que se pueda hablar de una cronopolítica asociada a la gestión política de la movilidad. Este aspecto del tema que nos ocupa, pese a su relevancia, no ha sido objeto de un estudio exhaustivo y detallado. El objetivo de este artículo es, precisamente, abordar la dimensión temporal de la gestión política de la movilidad desde el análisis y la reflexión teórica. Para ello, partiremos de la relación entre la gestión de la movilidad y la expropiación del tiempo, entendida como forma de dominación, para centrarnos seguidamente en una forma específica de dicha relación: la inmovilidad impuesta como desaceleración o espera crónica.

Diferencias de bienestar y política demográfica en el mediterráneo
Authors: Abellán García Antonio
Published: September 2018

Diferencias de bienestar y política demográfica en el Mediterráneo. El fuerte crecimiento demográfico de los países de la ribera meridional y oriental, el incremento consiguiente de su fuerza laboral, el escaso nivel de desarrollo económico y la percepción de las diferencias de bienestar con la otra ribera, son determinantes de un potencial emigratorio. Este potencial, la azarosa evolución política de los países meridionales, así como una demografía europea de incierto futuro y la intencionada dualidad Norte-Sur o Islam-Occidente, plantean una situación conflictiva en el mediterráneo. Las medidas instrumentadas para atenuar los contrastes demográficos y económicos no han dado resultados suficientes, por lo que es necesario un nuevo enfoque que considere que las políticas de población son políticas de desarrollo.

Phantoms and Phantasms: The Dialectical Image and the Practice of Translation in Contemporary American Poetry
Authors: Lavis Timothy A.
Published: September 2018

This paper employs an essentially Benjaminian method to examine recent translations of canonized poetry by contemporary American poets. In doing so, I posit a broadly applicable methodology for the critical study of translational texts. This methodology draws on Benjamin's concept of the dialectical image as well as Kenneth Goldsmith's recent problematization of the act of translation in order to consider the relationship between an original text and its translations—the commonalities and dissonances between the literary work and its reiterations. In doing so I suggest that this relationship between the text and its translations can be a productive site of examination for contemporary literary scholarship. Offering a case study for this methodology, this article explores the recent translations of Guillaume Apollinaire by Donald Revell and Ron Padgett as well as Anne Carson's translation of Sappho. Therein, I consider the ways these translational texts characterize and connect with the poetic past while responding to Marjorie Perloff's recent call for literary scholarship that engages foremost with literary concerns.
Management Accounting in Pricing Decisions for Real Estate of Real Estate Enterprises in Vietnam
Authors: Hương Pham Thanh
Published: September 2018

In Real Estate Enterprises (REEs), managers always have to make decisions while running their business in various forms. Among the manager’s decisions on real estate business, the pricing decision for real estate is one of the difficult decisions for managers in the REEs. Pricing decisions for real estate are often strategic decisions, which play an important role for the existence and development of REEs. Thus, enterprise managers often consider this to be the most important task for its historical mission and decisive factor of other tasks. This paper focuses on analyzing and evaluating the actual situation of Vietnam’s REEs in making pricing decisions for real estate, then proposing some recommendations for improving the information system and pricing decisions for real estate making process for creating the highest economic efficiency for the REEs in the current market conditions.

Published: September 2018

Based on the multi-index data of 11 cities in Guangdong-Hong Kong-Macao Greater Bay in 2016, the urban economic quality was calculated by TOPSIS method. Applying the modified gravitational model, the economy spatial linkage characteristics of core city-to-periphery city and periphery city-to-periphery city were analyzed. In addition, based on the method of network density analysis, centrality measures, core-periphery structure analysis to make a further verification about facts carried out from spatial connection analysis. This study shows that the Guangdong-Hong Kong-Macao Bay has an obvious core-periphery structure, and the overall economic network connection of Greater Bay is not strong. Guangdong-Shenzhen-Hong Kong is the core urban agglomeration in the Greater Bay Area. Dongguan and Foshan are transforming from marginal cities to semi-marginal cities. The marginal cities are limited by geographical distance or the economic environment, which leads to their development far behind the overall development of the Greater Bay Area. Finally, combined with the new wooden barrel theory and location advantage analysis method, advices were carried out to build a higher-level of the Greater Bay Area in future by dividing the Greater Bay Area into three major urban agglomerations. Urban agglomerations were proposed to meet the resources and industrial demands of the core urban imperfections and drive the economic development of the marginal cities at the same time.

The symbiotic system of Legumes and root-nodule bacteria is a significant process for enriching barren and dry soils and supporting plant growth. The aim of this study was to isolate root-nodule bacteria from Medicago falcate and to select high activity strains with resistance to environmental stress. As a result, only MSZ-25 strain grew in the medium containing 0.8M NaCl, with pH4.8-9.8 and at temperatures of 4-45°С. All rhizobial isolates were tolerant to the concentrations of 0.01-0.1% Pb(NO3)2, 0.01% ZnSO4, CdCI2, CuCI2 and NiCI2. The strains were also resisted to penicillin 10μ/ml, erythromycin 10μ/ml, and chlorampenicol 10μ/ml but the growths of all isolates were inhibited by kanamycin 30μ/ml, novobiocin 30μ/ml and tetracycline 10μ/ml.
IN-PROCESS CONTROL WITH A SENSORY TOOL HOLDER TO AVOID CHATTER
Authors: BLEICHER Friedrich , SCHÖRGHOFER Paul , HABERSOHN Christoph
Published: September 2018

Hydro-, steam- and gas- turbines, aircraft components or moulds are milled parts with complex geometries and high requirements for surface quality. The production of such industry components often necessitates the use of long and slender tools. However, instable machining situations together with work pieces with thin wall thickness can lead to dynamic instabilities in the milling processes. Resulting chatter vibrations cause chatter marks on the work piece surface and have influence on the tool lifetime. In order to detect and avoid the occurrence of process instabilities or process failures in an early stage, the Institute for Production Engineering and Laser Technology (IFT) developed an active control system to allow an in-process adaption of machining parameters. This system consists of a sensory tool holder with an integrated low cost acceleration sensor and wireless data transmission under real time conditions. A condition monitoring system using a signal-processing algorithm, which analyses the received acceleration values, is coupled to the NC- control system of the machine tool to apply new set points for feed rate and rotational speed depending on defined optimisation strategies. By the implementation of this system process instabilities can be avoided.

Published: September 2018

A central problem in automated assembly is the ramp-up phase. In order to achieve the required tolerances and cycle times, assembly parameters must be determined by extensive manual parameter variations. Therefore, the duration of the ramp-up phase represents a planning uncertainty and a financial risk, especially when high demands are placed on dynamics and precision. To complete this phase as efficiently as possible, comprehensive planning and experienced personnel are necessary. In this paper, we examine the use of machine learning techniques for the ramp-up of an automated assembly process. Specifically we use a deep artificial neural network to learn process parameters for pick-and-place operations of planar objects. We describe how the handling parameters of an industrial robot can be adjusted and optimized automatically by artificial neural networks and examine this approach in laboratory experiments. Furthermore, we test whether an artificial neural network can be used to optimize assembly parameters in process as an adaptive process controller. Finally, we discuss the advantages and disadvantages of the described approach for the determination of optimal assembly parameters in the ramp-up phase and during the utilization phase.
