Design and monitoring of serviceable product based on intelligent data acquisition and cumulative diagnosis: Keynote
No full textInternational audienceThis paper presents an innovative vision for designing equipment suitable for integrated services development by intelligent data acquisition all along the lifecycle. After construction, maintaining the equipment's functions required is one major factor on which depend the performances of the equipment during the remaining of its life. The author so considers the recurring problems that can shrink the expected performances of the equipment may be prevented, using information available firstly for monitoring health conditions of the equipment and secondly for maintenance decision support. The author then proposes to optimize data collection and information of the lifecycle by integrating intelligent data acquisition from the beginning of the equipment design. He also proposes an approach for improving the equipment's maintainability using intelligent systems health condition monitoring for enhancing the concept of service built-in product. Finally, he describes an example, implementing the intelligent data acquisition system for a cumulative diagnostic strategy deployment for equipment health condition monitoring and lifecycle management. The proposed diagnosis strategy, so-called “cumulative diagnosis”, is devised for advanced decision support to predictive maintenance
THE EXTRACURRICULAR CLASSES ORGANIZED THROUGH VOLUNTARY WORKS IN THE MOUNTAINOUS REGIONS FOR THE MEDIA STUDENT
No full textThe author of the present paper studies the scale and the outcomes of organizing the extracurricular classes through voluntary works in the mountain areas by evaluating the survey of participants' notion. This paper has 3 important categories: this article takes the reasons of choosing Vietnam's mountainous regions are in accord with voluntary activities into consideration, indicating the tasks and the process of carrying out extracurricular classes for students at faculty of the Multimedia Communication in Thang Long University. This paper aims to display an extracurricular learning model which is possible to carry out regularly for students in journalism and media in general. The purposes of this research do not only benefit the students but also the professor, lecturer and the whole educator because the significance of this work is that: the first is to engage students in their majors then helps them to apply their learned skills in practice, as well as contributes to renewing the traditional education at Vietnamese Universities
A non-abelian quasi-particle model for gluon plasma
No full textWe propose a quasi-particle model for the thermodynamic description of the gluon plasma which takes into account non-abelian characteristics of the gluonic field. This is accomplished utilizing massive non-linear plane wave solutions of the classical equations of motion with a variable mass parameter, reflecting the scale invariance of the Yang–Mills Lagrangian. For the statistical description of the gluon plasma we interpret these non-linear waves as quasi-particles with a temperature dependent mass distribution. Quasi-Gaussian distributions with a common variance but different temperature dependent mean masses for the longitudinal and transverse modes are employed. We use recent Lattice results to fix the mean transverse and longitudinal masses while the variance is fitted to the equation of state of pure SU(3) on the Lattice. Thus, our model succeeds to obtain both a consistent description of the gluon plasma energy density as well as a correct behavior of the mass parameters near the critical point. © 2016 The Author
Field-induced Kosterlitz-Thouless transition in the zero-temperature triangular Ising antiferromagnet
No full textWe investigate the zero-temperature triangular Ising antiferromagnet in a magnetic field by means of transfer matrix and Monte Carlo methods. The finite-size results are compared with predictions obtained from a mapping to the Gaussian model. The results confirm the presence of a field-induced Kosterlitz-Thouless transition to a state with long-range order

Microstructure and characteristics of the metal-ceramic composite (MgCa-HA/TCP) fabricated by liquid metal infiltration
No full textIn this article, a novel MgCa alloy-hydroxyapatite-tricalcium phosphate (HA/TCP) composite was fabricated using the liquid alloy infiltration technique. The feasibility of the composite for biomedical applications was studied through mechanical testing, electrochemical testing, immersion testing, and cell culture evaluation. It was shown that the composite had a strength about 200-fold higher than that of the original porous HA/TCP scaffold but retained half of the strength of the bulk MgCa alloy. The corrosion test indicated that the resulting composite exhibited an average corrosion rate of 0.029 mL cm(-2) h(-1) in the Hank's solution at 37 degrees C, which was slower than that of the bulk MgCa alloy alone. The indirect cytotoxicity evaluation revealed that 100% concentrated (i.e., undiluted or as-collected) extract of the MgCa-HA/TCP composite showed significant toxicity to L-929 and MG63 cells (p < 0.05). In contrast, the diluted extracts with 50 and 10% concentrations of the MgCa-HA/TCP composite exhibited a similar degree of cell viability (p > 0.05), equivalent to the grade I cytotoxicity of the standard ISO 10993-5: 1999.

Bayesian spatial analysis of a national urinary schistosomiasis questionnaire to assist geographic targeting of schistosomiasis control in Tanzania, East Africa.
No full textSpatial modelling was applied to self-reported schistosomiasis data from over 2.5 million school students from 12,399 schools in all regions of mainland Tanzania. The aims were to derive statistically robust prevalence estimates in small geographical units (wards), to identify spatial clusters of high and low prevalence and to quantify uncertainty surrounding prevalence estimates. The objective was to permit informed decision-making for targeting of resources by the Tanzanian national schistosomiasis control programme. Bayesian logistic regression models were constructed to investigate the risk of schistosomiasis in each ward, based on the prevalence of self-reported schistosomiasis and blood in urine. Models contained covariates representing climatic and demographic effects and random effects for spatial clustering. Degree of urbanisation, median elevation of the ward and median normalised difference vegetation index (NDVI) were significantly and negatively associated with schistosomiasis prevalence. Most regions contained wards that had >95% certainty of schistosomiasis prevalence being >10%, the selected threshold for bi-annual mass chemotherapy of school-age children. Wards with >95% certainty of schistosomiasis prevalence being >30%, the selected threshold for annual mass chemotherapy of school-age children, were clustered in north-western, south-western and south-eastern regions. Large sample sizes in most wards meant raw prevalence estimates were robust. However, when uncertainties were investigated, intervention status was equivocal in 6.7-13.0% of wards depending on the criterion used. The resulting maps are being used to plan the distribution of praziquantel to participating districts; they will be applied to prioritising control in those wards where prevalence was unequivocally above thresholds for intervention and might direct decision-makers to obtain more information in wards where intervention status was uncertain
