</p> <p class="card-text"><strong>Abstract:</strong></p> To be competitive and sustainable, any company has to maximize its value. However, unlike listed companies that can assess their values based on market shares, most Small and Medium Enterprises (SMEs) which are non-listed cannot have direct and live access to this critical information. Traditional accounting reports only give limited insights to SME decision-makers about the real impact of their day-to-day decisions on the company’s performance and value. Most of the time, an SME’s financial valuation is made one time a year as the associated process is time and resource-consuming, requiring several months and external expertise to be completed. To solve this issue, we propose in this paper a value-oriented metamodel that enables real-time and dynamic assessment of the SME’s value based on the large definition of their assets. These assets cover a wider scope of resources of the company and better account for immaterial assets. The proposal, which is illustrated in a case study, discusses the benefits of incorporating assets in the SME valuation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SME" title="SME">SME</a>, <a href="https://publications.waset.org/abstracts/search?q=metamodel" title=" metamodel"> metamodel</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20support%20system" title=" decision support system"> decision support system</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20valuation" title=" financial valuation"> financial valuation</a>, <a href="https://publications.waset.org/abstracts/search?q=assets" title=" assets"> assets</a> </p> <a href="https://publications.waset.org/abstracts/155809/a-value-oriented-metamodel-for-small-and-medium-enterprises-decision-making" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155809.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Linking Milk Price and Production Costs with Greenhouse Gas Emissions of Luxembourgish Dairy Farms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rocco%20Lioy">Rocco Lioy</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%20Dusseldorf"> Tom Dusseldorf</a>, <a href="https://publications.waset.org/abstracts/search?q=Aline%20Lehnen"> Aline Lehnen</a>, <a href="https://publications.waset.org/abstracts/search?q=Romain%20Reding"> Romain Reding</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A study concerning both the rentability and ecological performance of dairy production in Luxembourg was carried out for the years 2017, 2018 and 2019. The data of 100 dairy farms, referring to the Greenhouse gas emissions (ecology) and the profitability (economy) of dairy production, were evaluated, and the average was compared to the corresponding figures of 80 Luxembourgish dairy farms evaluated in the years 2014, 2015 and 2016. The ecological evaluation could confirm that farm efficiency (especially defined as the lowest ratio between used feedstuff and produced milk) is the key driver for significantly reducing the level of emissions in dairy farms. In both farm groups and in the two periods, the efficient farms show almost the same level of emissions per kg ECM (1,17 kg CO2-eq) in comparison with intensive farms (1,13 kg CO2-eq), and at the same time a by far lowest level of emissions related to the production surface (9,9 vs. 13,9 t CO2-eq/ha). Concerning the economic performances, it could be observed that in the years 2017, 2018 and 2019, the intensive farms (we define intensity in the first place in terms of produced milk pro ha) reached a higher profit (incomes minus costs, only consideration for subsidies) than the efficient farms (4,8 vs. 2,6 €-cent/kg ECM), in contradiction with the observation of the years 2014, 2015 and 2015 (1,5 vs. 3,7 €-cent/kg ECM). The most important reason for this divergent behavior was a change in income and cost structure in the considered periods. In the last period (2017, 2018 and 2019), the milk price was considerably higher than in the previous period, and the production costs were lower. This was of advantage for intensive farms, which produce the highest quantity of milk with a high amount of production means. In the period 2014, 2015 and 2016, with lower milk prices but comparable production costs, the advantage was with efficient farms. In conclusion, we expect that in the next future, when especially the production costs will presumably be much higher than in the last years, the profitableness of dairy farming will decrease. In this case, we assume that efficient farms will provide not only an ecologically but also an economically better performance than production-intensive farms. High milk prices and low production costs are no good incentives for carbon-smart farming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=efficiency" title="efficiency">efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=intensity" title=" intensity"> intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy" title=" dairy"> dairy</a>, <a href="https://publications.waset.org/abstracts/search?q=emissions" title=" emissions"> emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=prices" title=" prices"> prices</a>, <a href="https://publications.waset.org/abstracts/search?q=costs" title=" costs"> costs</a> </p> <a href="https://publications.waset.org/abstracts/163573/linking-milk-price-and-production-costs-with-greenhouse-gas-emissions-of-luxembourgish-dairy-farms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163573.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">96</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Net Neutrality and Asymmetric Platform Competition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Romain%20Lestage">Romain Lestage</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20Bourreau"> Marc Bourreau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we analyze the interplay between access to the last-mile network and net neutrality in the market for Internet access.

Malnutrition, on the other hand, is defined as inadequate, imbalanced, or excessive consumption of macronutrients, micronutrients, or both, which is characterized as an abnormal physiological condition. Oral health is impacted by malnutrition, and malnutrition can result from poor oral health. The objective of this paper was to study the association of serum Vitamin D level and body mass index as representatives of malnutrition at micro and macro levels, respectively, on dental caries. Results showed that: 1. The majority of the population studied (70%) are Vitamin D deficient. 2. Having a normal and even a sufficient level of serum Vitamin D and having a normal body mass index increase the chances of children being caries-free and having a lower caries index. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children" title="children">children</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20Caries" title=" dental Caries"> dental Caries</a>, <a href="https://publications.waset.org/abstracts/search?q=malnutrition" title=" malnutrition"> malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20D" title=" vitamin D"> vitamin D</a> </p> <a href="https://publications.waset.org/abstracts/159138/association-between-malnutrition-and-dental-caries-in-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159138.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Environmental Efficacy on Heracleum persicum Essential Oils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahele%20Hasani">Rahele Hasani</a>, <a href="https://publications.waset.org/abstracts/search?q=Iraj%20Mehregan"> Iraj Mehregan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kambiz%20Larijani"> Kambiz Larijani</a>, <a href="https://publications.waset.org/abstracts/search?q=Taher%20Nejadsattari"> Taher Nejadsattari</a>, <a href="https://publications.waset.org/abstracts/search?q=Romain%20Scalone"> Romain Scalone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Essential oils of <em>Heracleum persicum</em> (Apiaceae) have been widely used from many years ago, but the difference of its properties among different populations have not been identified up to now. Hydrodistilation Clevenger type was used to obtaining the fruit essential oils of four populations of <em>H. persicum</em> from different localities in Iran, then they were characterized by GC-FID and GC-MS analyses. Some ecological factors were also measured. The oils of four populations were compared to determine the similarities and differences and the relationships between these factors and ecological factors. Based on the result, 18-32 different components were identified in four populations, while the percentage of the main components was higher in population with lower number of components. According to the statistical analyses of chemical components and ecological factors, it can be concluded that some ecological factors such as altitude, less humidity, high difference between day and night temperature and salty soil would lead to lower number of components in essential oil, whereas they consist the higher percentage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chemotaxonomy" title="Chemotaxonomy">Chemotaxonomy</a>, <a href="https://publications.waset.org/abstracts/search?q=Persian%20hogweed" title=" Persian hogweed"> Persian hogweed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecological%20factors" title=" Ecological factors"> Ecological factors</a>, <a href="https://publications.waset.org/abstracts/search?q=Apiaceae." title=" Apiaceae."> Apiaceae.</a> </p> <a href="https://publications.waset.org/abstracts/47089/environmental-efficacy-on-heracleum-persicum-essential-oils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47089.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">430</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Heat Transfer Enhancement by Localized Time Varying Thermal Perturbations at Hot and Cold Walls in a Rectangular Differentially Heated Cavity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Thiers">Nicolas Thiers</a>, <a href="https://publications.waset.org/abstracts/search?q=Romain%20Gers"> Romain Gers</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Skurtys"> Olivier Skurtys</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we study numerically the effect of a thermal perturbation on the heat transfer in a rectangular differentially heated cavity of aspect ratio 4, filled by air. In order to maintain the center symmetry, the thermal perturbation is imposed by a square wave at both active walls, at the same relative position of the hot or cold boundary layers. The influences of the amplitude and the vertical location of the perturbation are investigated. The air flow is calculated solving the unsteady Boussinesq-Navier-Stokes equations using the PN - PN-2 Spectral Element Method (SEM) programmed in the Nek5000 opencode, at RaH= 9x107, just before the first bifurcation which leads to periodical flow. The results show that the perturbation has a major impact for the highest amplitude, and at about three quarters of the cavity height, upstream, in both hot and cold boundary layers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20numerical%20simulation" title="direct numerical simulation">direct numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer%20enhancement" title=" heat transfer enhancement"> heat transfer enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=localized%20thermal%20perturbations" title=" localized thermal perturbations"> localized thermal perturbations</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20convection" title=" natural convection"> natural convection</a>, <a href="https://publications.waset.org/abstracts/search?q=rectangular%20differentially-heated%20cavity" title=" rectangular differentially-heated cavity"> rectangular differentially-heated cavity</a> </p> <a href="https://publications.waset.org/abstracts/109171/heat-transfer-enhancement-by-localized-time-varying-thermal-perturbations-at-hot-and-cold-walls-in-a-rectangular-differentially-heated-cavity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109171.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Characterization of Sorption Behavior and Mass Transfer Properties of Four Central Africa Tropical Woods </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Merlin%20Simo%20Tagne">Merlin Simo Tagne</a>, <a href="https://publications.waset.org/abstracts/search?q=Romain%20R%C3%A9mond"> Romain Rémond</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study provides the sorption isotherm, its hysteresis and their mass transfer properties of four Central Africa Tropical woods largely used for building construction: frake, lotofa, sapelle and ayous. Characterization of these three species in particular and Central Africa tropical woods, in general, was necessary to develop conservation and treatment of wood after first transformation using the drying. Isotherms were performed using a dynamic vapor sorption apparatus (Surface Measurement Systems) at 20 and 40°C. The mass diffusivity was determined in steady state using a specific vapometer. Permeability was determined using a specialized device developed to measure over a wide range of permeability values. Permeability and mass transfer properties are determined in the tangential direction with a ‘false’ quartersawn cutting (sapelle and lotofa) and in the radial direction with a ‘false’ flatsawn cutting (ayous and frake). The sample of sapelle, ayous and frake are heartwood when lotofa contains as well as heartwood than sapwood. Results obtained showed that the temperature effect on sorption behavior was low than relative humidity effect. We also observed a low difference between the sorption behavior of our woods and hysteresis of sorption decreases when the temperature increases. Hailwood-Horrobin model’s predicts the isotherms of adsorption and desorption of ours woods and parameters of this model are proposed. Results on the characterization of mass transfer properties showed that, in the steady state, mass diffusivity decreases exponentially when basal density increases. In the phase of desorption, mass diffusivity is great than in the phase of adsorption. The permeability of ours woods are greater than Australian hardwoods but lower than temperate woods. It is difficult to define a relationship between permeability and mass diffusivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tropical%20woods" title="tropical woods">tropical woods</a>, <a href="https://publications.waset.org/abstracts/search?q=sorption%20isotherm" title=" sorption isotherm"> sorption isotherm</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion%20coefficient" title=" diffusion coefficient"> diffusion coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20permeability" title=" gas permeability"> gas permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=Central%20Africa" title=" Central Africa"> Central Africa</a> </p> <a href="https://publications.waset.org/abstracts/14845/characterization-of-sorption-behavior-and-mass-transfer-properties-of-four-central-africa-tropical-woods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14845.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">496</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Murine Pulmonary Responses after Sub-Chronic Exposure to Environmental Ultrafine Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yara%20Saleh">Yara Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastien%20Antherieu"> Sebastien Antherieu</a>, <a href="https://publications.waset.org/abstracts/search?q=Romain%20Dusautoir"> Romain Dusautoir</a>, <a href="https://publications.waset.org/abstracts/search?q=Jules%20Sotty"> Jules Sotty</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurent%20Alleman"> Laurent Alleman</a>, <a href="https://publications.waset.org/abstracts/search?q=Ludivine%20Canivet"> Ludivine Canivet</a>, <a href="https://publications.waset.org/abstracts/search?q=Esperanza%20Perdrix"> Esperanza Perdrix</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Dubot"> Pierre Dubot</a>, <a href="https://publications.waset.org/abstracts/search?q=Anne%20Platel"> Anne Platel</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabrice%20Nesslany"> Fabrice Nesslany</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillaume%20Garcon"> Guillaume Garcon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Marc%20Lo-Guidice"> Jean-Marc Lo-Guidice</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Air pollution is one of the leading causes of premature death worldwide. Among air pollutants, particulate matter (PM) is a major health risk factor, through the induction of cardiopulmonary diseases and lung cancers. They are composed of coarse, fine and ultrafine particles (PM10, PM2.5, and PM0.1 respectively). Ultrafine particles are emerging unregulated pollutants that might have greater toxicity than larger particles, since they are more abundant and consequently have higher surface area per unit of mass. Our project aims to develop a relevant in vivo model of sub-chronic exposure to atmospheric particles in order to elucidate the specific respiratory impact of ultrafine particles compared to fine particulate matter. Quasi-ultrafine (PM0.18) and fine (PM2.5) particles have been collected in the urban industrial zone of Dunkirk in north France during a 7-month campaign, and submitted to physico-chemical characterization. BALB/c mice were then exposed intranasally to 10µg of PM0.18 or PM2.5 3 times a week. After 1 or 3-month exposure, broncho alveolar lavages (BAL) were performed and lung tissues were harvested for histological and transcriptomic analyses. The physico-chemical study of the collected particles shows that there is no major difference in elemental and surface chemical composition between PM0.18 and PM2.5. Furthermore, the results of the cytological analyses carried out show that both types of particulate fractions can be internalized in lung cells. However, the cell count in BAL and preliminary transcriptomic data suggest that PM0.18 could be more reactive and induce a stronger lung inflammation in exposed mice than PM2.5. Complementary studies are in progress to confirm these first data and to identify the metabolic pathways more specifically associated with the toxicity of ultrafine particles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20pollution" title="environmental pollution">environmental pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20affect" title=" lung affect"> lung affect</a>, <a href="https://publications.waset.org/abstracts/search?q=mice" title=" mice"> mice</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrafine%20particles" title=" ultrafine particles"> ultrafine particles</a> </p> <a href="https://publications.waset.org/abstracts/71627/murine-pulmonary-responses-after-sub-chronic-exposure-to-environmental-ultrafine-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71627.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">238</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Evolutions of Structural Properties of Native Phospho Casein (NPC) Powder during Storage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Nasser">Sarah Nasser</a>, <a href="https://publications.waset.org/abstracts/search?q=Anne%20Moreau"> Anne Moreau</a>, <a href="https://publications.waset.org/abstracts/search?q=Alain%20Hedoux"> Alain Hedoux</a>, <a href="https://publications.waset.org/abstracts/search?q=Romain%20Jeantet"> Romain Jeantet</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillaume%20Delaplace"> Guillaume Delaplace</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Spray dryed powders containing some caseins are commonly produced in dairy industry. It is widely admitted that the structure of casein evolves during powder storage, inducing a loss of solubility. However few studies evaluate accurately the destabilization mechanisms at molecular and mesoscopic level, in particular for Native Phospho Casein powder (NPC). Consequently, at the state of the art, it is very difficult to assess which secondary structure change or crosslinks initiate insolubility during storage. To address this issue, controlled ageing conditions have been applied to a NPC powder (which was obtained by spray drying a concentrate containing a higher content of casein (90%), whey protein (8%) and lactose (few %)). Evolution of structure and loss of solubility, with the effects of temperature and time of storage were systematically reported. Methods: FTIR spectroscopy, Raman and Circular Dichroism were used to monitor changes of secondary structure in dry powder and in solution after rehydration. Besides, proteomic tools and electrophoresis have been performed after varying storage conditions for evaluating aggregation and post translational modifications, like lactosylation or phosphorylation. Finally, Tof Sims and MEB were used to follow in parallel evolution of structure in surface and skin formation due to storage. Results + conclusion: These results highlight the important role of storage temperature in the stability of NPC. It is shown that this is not lactosylation at the heart of formation of aggregates, as advanced in others publications This is almost the rise of multitude post translational modifications (chemical cross link), added to disulphide bridges (physical cross link) wich contribute to the destabilisation of structure and aggregation of casein. A relative quantification of each kind of cross link, source of aggregates, is proposed. In addition, it has been proved that migration of lipids and formation of skin in surface during the ageing also explains the evolution of structure casein and thus the alterations of functional properties of NPC powder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=casein" title="casein">casein</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20link" title=" cross link"> cross link</a>, <a href="https://publications.waset.org/abstracts/search?q=powder" title=" powder"> powder</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a> </p> <a href="https://publications.waset.org/abstracts/48852/evolutions-of-structural-properties-of-native-phospho-casein-npc-powder-during-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48852.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">379</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Identification of Failures Occurring on a System on Chip Exposed to a Neutron Beam for Safety Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Thomet">S.

Romain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a hardware module dedicated to understanding the fail reason of a System on Chip (SoC) exposed to a particle beam. Impact of Single-Event Effects (SEE) on processor-based SoCs is a concern that has increased in the past decade, particularly for terrestrial applications with automotive safety increasing requirements, as well as consumer and industrial domains. The SEE created by the impact of a particle on an SoC may have consequences that can end to instability or crashes. Specific hardening techniques for hardware and software have been developed to make such systems more reliable. SoC is then qualified using cosmic ray Accelerated Soft-Error Rate (ASER) to ensure the Soft-Error Rate (SER) remains in mission profiles. Understanding where errors are occurring is another challenge because of the complexity of operations performed in an SoC. Common techniques to monitor an SoC running under a beam are based on non-intrusive debug, consisting of recording the program counter and doing some consistency checking on the fly. To detect and understand SEE, we have developed a module embedded within the SoC that provide support for recording probes, hardware watchpoints, and a memory mapped register bank dedicated to software usage. To identify CPU failure modes and the most important resources to probe, we have carried out a fault injection campaign on the RTL model of the SoC. Probes are placed on generic CPU registers and bus accesses. They highlight the propagation of errors and allow identifying the failure modes. Typical resulting errors are bit-flips in resources creating bad addresses, illegal instructions, longer than expected loops, or incorrect bus accesses. Although our module is processor agnostic, it has been interfaced to a RISC-V by probing some of the processor registers. Probes are then recorded in a ring buffer. Associated hardware watchpoints are allowing to do some control, such as start or stop event recording or halt the processor. Finally, the module is also providing a bank of registers where the firmware running on the SoC can log information. Typical usage is for operating system context switch recording. The module is connected to a dedicated debug bus and is interfaced to a remote controller via a debugger link. Thus, a remote controller can interact with the monitoring module without any intrusiveness on the SoC. Moreover, in case of CPU unresponsiveness, or system-bus stall, the recorded information can still be recovered, providing the fail reason. A preliminary version of the module has been integrated into a test chip currently being manufactured at ST in 28-nm FDSOI technology. The module has been triplicated to provide reliable information on the SoC behavior. As the primary application domain is automotive and safety, the efficiency of the module will be evaluated by exposing the test chip under a fast-neutron beam by the end of the year. In the meantime, it will be tested with alpha particles and electromagnetic fault injection (EMFI). We will report in the paper on fault-injection results as well as irradiation results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fault%20injection" title="fault injection">fault injection</a>, <a href="https://publications.waset.org/abstracts/search?q=SoC%20fail%20reason" title=" SoC fail reason"> SoC fail reason</a>, <a href="https://publications.waset.org/abstracts/search?q=SoC%20soft%20error%20rate" title=" SoC soft error rate"> SoC soft error rate</a>, <a href="https://publications.waset.org/abstracts/search?q=terrestrial%20application" title=" terrestrial application"> terrestrial application</a> </p> <a href="https://publications.waset.org/abstracts/128987/identification-of-failures-occurring-on-a-system-on-chip-exposed-to-a-neutron-beam-for-safety-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128987.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">229</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Narratives of Self-Renewal: Looking for A Middle Earth In-Between Psychoanalysis and the Search for Consciousness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marilena%20Fatigante">Marilena Fatigante</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Contemporary psychoanalysis is increasingly acknowledging the existential demands of clients in psychotherapy. A significant aspect of the personal crises that patients face today is often rooted in the difficulty to find meaning in their own existence, even after working through or resolving traumatic memories and experiences. Tracing back to the correspondence between Freud and Romain Rolland (1927), psychoanalysis could not ignore that investigation of the psyche also encompasses the encounter with deep, psycho-sensory experiences, which involve a sense of "being one with the external world as a whole", the well-known “oceanic feeling”, as Rolland posed it. Despite the recognition of Non-ordinary States of Consciousness (NSC) as catalysts for transformation in clinical practice, highlighted by neuroscience and results from psychedelic-assisted therapies, there is few research on how psychoanalytic knowledge can integrate with other treatment traditions. These traditions, commonly rooted in non -Western, unconventional, and non-formal psychological knowledge, emphasize the individual’s innate tendency toward existential integrity and transcendence of self-boundaries. Inspired by an autobiographical account, this paper examines narratives of 12 individuals, who engaged in psychoanalytic therapy and also underwent treatment involving a non-formal helping relationship with an expert guide in consciousness, which included experience of this nature. The guide relies on 35 yrs of experience in Psychological, multidisciplinary studies in Human Sciences and Art, and demonstrates knowledge of many wisdom traditions, ranging from Eastern to Western philosophy, including Psychoanalysis and its development in cultural perspective (e.g, Ethnopsychiatry). Analyses focused primarily on two dimensions that research has identified as central in assessing the degree of treatment “success” in the patients’ narrative accounts of their therapies: agency and coherence, defined respectively as the increase, expressed in language, of the client’s perceived ability to manage his/her own challenges and the capacity, inherent in “narrative” itself as a resource for meaning making (Bruner, 1990), to provide the subject with a sense of unity, endowing his /her life experience with temporal and logical sequentiality. The present study reports that, in all narratives from the participants, agency and coherence are described differently than in “common” psychotherapy narratives. Although the participants consistently identified themselves as responsible agentic subject, the sense of agency derived from the non-conventional guidance pathway is never reduced to a personal, individual accomplishment. Rather, the more a new, fuller sense of “Life” (more than “Self”) develops out of the guidance pathway they engage with the expert guide, the more they “surrender” their own sense of autonomy and self-containment. Something, which Safran (2016) identified as well talking about the sense of surrender and “grace” in psychoanalytic sessions. Secondly, narratives of individuals engaging with the expert guide describe coherence not as repairing or enforcing continuity but as enhancing their ability to navigate dramatic discontinuities, falls, abrupt leaps and passages marked by feelings of loss and bereavement. The paper ultimately explores whether valid criteria can be established to analyze experiences of non-conventional paths of self-evolution. These paths are not opposed or alternative to conventional ones, and should not be simplistically dismissed as exotic or magical. <p class="card-text"><strong>Keywords:</strong> <a
