RDF to Conceptual Graphs Translations

International audienceIn this paper we will discuss two different translations between RDF (Resource Description Format) and Conceptual Graphs (CGs). These translations will allow tools like Cogui and Cogitant to be able to import and export RDF(S) documents. The first translation is sound and complete from a reasoning view point but is not visual nor a representation in the spirit of Conceptual Graphs (CGs). The second translation has the advantage of being natural and fully exploiting the CG features, but, on the other hand it does not apply to the whole RDF(S). We aim this paper as a preliminary report of ongoing work looking in detail at different pro and the cons of each approach

Quantum Transport in a Nanosize Silicon-on-Insulator Metal-Oxide-Semiconductor

An approach is developed for the determination of the current flowing through a nanosize silicon-on-insulator (SOI) metal-oxide-semiconductor field-effect transistors (MOSFET). The quantum mechanical features of the electron transport are extracted from the numerical solution of the quantum Liouville equation in the Wigner function representation. Accounting for electron scattering due to ionized impurities, acoustic phonons and surface roughness at the Si/SiO2 interface, device characteristics are obtained as a function of a channel length. From the Wigner function distributions, the coexistence of the diffusive and the ballistic transport naturally emerges. It is shown that the scattering mechanisms tend to reduce the ballistic component of the transport. The ballistic component increases with decreasing the channel length.Comment: 21 pages, 8 figures, E-mail addresses: [email protected]

Introducing Preference-Based Argumentation to Inconsistent Ontological Knowledge Bases

International audienceHandling inconsistency is an inherent part of decision making in traditional agri-food chains – due to the various concerns involved. In order to explain the source of inconsistency and represent the existing conflicts in the ontological knowledge base, argumentation theory can be used. However, the current state of art methodology does not allow to take into account the level of significance of the knowledge expressed by the various ontological knowledge sources. We propose to use preferences in order to model those differences between formulas and evaluate our proposal practically by implementing it within the INRA platform and showing a use case using this formalism in a bread making decision support system

Interaction Properties of the Periodic and Step-like Solutions of the Double-Sine-Gordon Equation

The periodic and step-like solutions of the double-Sine-Gordon equation are investigated, with different initial conditions and for various values of the potential parameter $\epsilon$. We plot energy and force diagrams, as functions of the inter-soliton distance for such solutions. This allows us to consider our system as an interacting many-body system in 1+1 dimension. We therefore plot state diagrams (pressure vs. average density) for step-like as well as periodic solutions. Step-like solutions are shown to behave similarly to their counterparts in the Sine-Gordon system. However, periodic solutions show a fundamentally different behavior as the parameter $\epsilon$ is increased. We show that two distinct phases of periodic solutions exist which exhibit manifestly different behavior. Response functions for these phases are shown to behave differently, joining at an apparent phase transition point.Comment: 17pages, 15 figure

Aspects of the population morbidity in some regions of the Republic of Moldova

General Hygiene Department, Nicolae Testemitsanu State University of Medicine and Pharmacy, National Centre of Public Health, Chisinau, the Republic of MoldovaBackground: The health of the Moldovan population requires special attention, due to direct and indirect biological, environmental, behavioural and health factors. Material and methods: We studied population morbidity from the following localities: town Cupcini, village Bratuseni, village Ruseni (Edinet district); town Vadul lui Voda, town Cricova, village Condrita (municipality Chisinău); village Rosu, village Moscovei, village Huluboaia (Cahul district). Statistical data were taken from the statistical report No 12, for the period from 2012 to 2014. Results: Morbidity analysis showed that the overall prevalence of increased average values was recorded in the village Bratuseni, Edinet district – 16119.0±247.70/000. In town Vadul lui Voda, Cricova, village Condriţa (municipality Chisinau), overall prevalence values ranged within 6967.0±813.0 – 8721.3±375.90/000. Meanwhile, village Rosu, village Moscovei, village Huluboaia (Cahul district), mean values of overall prevalence were included within 2379.8±574.8 and 3219.8±152.70/000. Analysis of the general incidence emphasized that the community in the North recorded mean values within 1370.5±0.7 – 11162.4±190.40/000, localities in the center and south - 1877.8±246.3 – 3149.0±187.80/000 and respectively 899.3±95.0 – 1244.8±339.80/000. Conclusions: Population morbidity was growing during 2012-2014. Prevalence of diseases of the circulatory, digestive and urogenital systems was higher in central areas and the osteoarticular system diseases – in northern communities. The incidence of cardiovascular, urogenital and osteoarticular diseases was higher in cities from North, and digestive system diseases – in central areas

PRELIMINARY RESULTS ON THE ACTION OF PLANT EXTRACTS ON GERMINATION AND ROOT GROWTH PROCESSES IN SEEDS OF PLANT SPECIES GROWN ON SANDY SOILS

In the context of global climate change, Romania is also seeing changes related mainly to the annual average temperature increase of about 1.6 ° C, the increase in summer temperatures (July and August), which led to changes in the biology of the diseases and pests. Combating crop pests is done through several methods: physical-mechanical (thermal disinfections of seeds), chemical (using pesticides), agro-technical (through soil works, including weeds) but also biological (by using natural and of antagonistic organisms). Bioproducts are biological means made on the basis of natural compounds (plant extracts) with a complex action on crop plants, biopreparations that have been shown to be stimulants of vegetative growth. Application of bioproducts is done by treatments, which are either seed treatments or treatments in vegetation (sprays with different volumes of liquid). In 2016 at CCDCPN Dăbuleni, were tested the basil oil for cowpea seeds, mint oil for peanut seeds, santal oil  for green melon seeds to germination and root growth.

Brainwaves and Sound Synchronization in a Dance Performance

In a previous work (Lucchiari and Folgieri, 2015) we considered communication among young people. New digital-natives do not communicate in a traditional way, but they choose different means and ways. It is not a surprising conclusion that a large part of digital-natives considers obsolete both Web sites\u2019 structure and Internet navigation modes, learning instruments and paradigms and communication tools, choosing, instead, fast and immediate media like mobile phone communication, social networking and so on (Croitoru et al. 2011). Notwithstanding we could think they lack of communication skills, actually, they communicate with each other much more than ever done, using not only the verbal language, but also images, videos, sounds, and especially emotions. We named this phenomenon telepatheia or, better, sympateia, meaning that they seem to keep in contact independently by the mean. Of course, on our intention, this does not mean that we are observing a new organic evolution, but surely a kind of evolution can be traced: an era in which human and machines are evolving, influencing one each other, determining a specific kind of communication strongly influenced and related to technology. In this paper, starting from our previous studies and from our concept of \u201csympateia\u201d, we performed a new experiment related to brain rhythms synchronization. Through our experiment, described in the following chapter, We want to explore the communication mechanisms of telepathy (in the ancient Greek assumption of \u201ctelepatia\u201d\uf020that is [tele]=\u201ddistance\u201d and [pateia]=\u201demotion, feeling\u201d). This does not mean that we are trying to make humans telepathic, but we aim to deeply understand communication mechanisms among humans through human-computer interaction BCI devices. This means to change the point of view of brain and Information Technology researches, stressing the point of view of self-understanding of the own brain

Deposition temperature influence on the wear behaviour of carbon-based coatings deposited on hardened steel

An evaluation regarding the influence of substrate material characteristics and deposition parameters on the tribological behaviour of carbon-based is presented. Chromium nitride interlayers and carbon-based thin films were deposited on hardened AISI 5115 case hardening steel, by magnetron sputtering. The physical vapour deposition (PVD) deposition was performed at three different temperatures: 180 °C, 200 °C and 250 °C. The chemical composition of the samples was assessed by Rutherford Backscattering Spectroscopy (RBS), the structure by X-ray Diffraction (XRD), and the surface morphology by Atomic Force Microscopy (AFM). The surface chemistry was analysed by X-ray Photoelectron Spectroscopy (XPS) and Raman Spectroscopy. The coatings are homogeneous, amorphous, with a smooth surface. The mechanical behaviour has been assessed on a pin-on disk rotational tribometer (wear characteristics), on a micro scratch tester (adhesion to the substrate), by ball-cratering (film thickness); by nanoindentation (hardness and the modulus of elasticity). A strong correlation between the substrate characteristics, but more importantly, of the deposition temperature, on one hand, and the mechanical characteristics, on the other hand, has been observed. The fracture toughness is positively influenced by the presence of the ceramic interlayer (chromium nitride). The modulus of elasticity and friction coefficient (both in dry conditions and lubricated) are decreased for higher deposition temperatures, however the higher deposition temperature negatively affects the hardness of the steel substrate.We hereby acknowledge the structural funds project PRO-DD (POSCCE, O.2.2.1., ID 123, SMIS 2637, ctr. no 11/2009) for providing some of the infrastructure used in this work
