    Funding: This research was partially supported by funds provided by the European Commission in the scope of FoF/H2020-723710 vf-OS, ICT/H2020-825631 ZDMP projects, and by the FCT— Fundação para a Ciência e a Tecnologia in the scope of UIDB/00066/2020 related to CTS—Centro de Tecnologia e Sistemas research unit.In the last decades, the increasing complexity of industrial information technology has led to the emergence of new trends in manufacturing. Factories are using multiple Internet of Things (IoT) platforms to harvest sensor information to improve production. Such a transformation contributes to efficiency growth and reduced production costs. To deal with the heterogeneity of the services within an IoT system, Service-Oriented Architecture (SOA) is referred to in the literature as being advantageous for the design and development of software to support IoT-based production processes.The aim of SOA-based design is to provide the leverage to use and reuse loosely coupled IoT services at the middleware layer to minimise system integration problems. We propose a system architecture that follows the SOA architectural pattern and enables developers and business process designers to dynamically add, query or use instances of existing modular software in the IoT context. Furthermore, an analysis of utilization of modular software that presents some challenges and limitations of this approach is also in the scope of this workpublishersversionpublishe

    The research leading to these results has received funding from the European Unions Horizon 2020 research and innovation program, mainly project ZDMP under grant agreement 825631, and Eur3ka, TALON, and RE4DY, EU H2020 projects under grant agreements 101016175, 101070181, and 101058384 accordingly.Zero-Defect Manufacturing (ZDM) is the next evolutionary step in quality management for manufacturing that makes use of Industry 4.0 technologies to support quality in manufacturing. These technologies help reduce the cost of inspection, allowing for more inspection points throughout the manufacturing process, reducing the size of quality feedback loops, and guaranteeing that no defective product is delivered to the customer. There are several ZDM-related initiatives, but still no harmonized terminology. This article describes the methodological approach to provide a common agreement on the ZDM concept and its associated terminology taking place within an open CENCENELEC Workshop. The methodology has the support of ISO standards for terminology work such as ISO 704, ISO 860, and ISO 10241–1/2. This work shows that the terminology for ZDM has a significant overlap with the terminology of quality management, metrology, dependability, statistics, non-destructive inspection, and condition monitoring. The proposed new terms and definitions can be used to further extend ISO’s and IEC’s already available terminologies and support present and future researchers in the field to conduct their research using a common vocabulary.publishersversionpublishe

    Data Management Component for Virtual Factories Systems

    No full text
    The vf-OS project aims to develop a middleware platform for the virtual factory of the future. The vf-OS is composed of several modules providing interoperability mechanisms for systems to exchange real-time data. Moreover, it enables the managing of data flows, transforming data, providing open API’s to ease integration process. The proposed Data Management Component (DMC) intends to cover the issues related to data handling, pre-processing, extracting, and data flows management for Virtual Factories. It integrates four subcomponents: a data infrastructure middleware element that handles the data communications; a data storage mechanism able to work with high loads and triples; a semantic and mapping function to establish model information integration; and an analytical module composed by machine learning and prediction mechanisms to enable knowledge extraction from the vast amount of data generated by the associated virtual factory system

    The production cross section of electrons from semileptonic decays of beauty hadrons was measured at mid-rapidity (|y| < 0.8) in the transverse momentum range 1 < pt < 8 Gev/c with the ALICE experiment at the CERN LHC in pp collisions at a center of mass energy sqrt{s} = 7 TeV using an integrated luminosity of 2.2 nb^{-1}. Electrons from beauty hadron decays were selected based on the displacement of the decay vertex from the collision vertex. A perturbative QCD calculation agrees with the measurement within uncertainties. The data were extrapolated to the full phase space to determine the total cross section for the production of beauty quark-antiquark pairs

    Duchenne muscular dystrophy is one of the most common forms of childhood muscular dystrophies. Its incidence is 1 in 3.5–6 thousand newborn boys according to various sources. The disease is caused by the mutation in the DMD gene coding the dystrophin protein, it leads to the dystrophin absence or malfunction. The disease is characterized by proximal muscle weakness and gastrocnemius muscles pseudohypertrophy. In average, patients lose the ability to walk by themselves by the age of 11 and become nonambulatory. The authors have present modern epidemiological data and etiopathogenesis features of Duchenne muscular dystrophy, and have described clinical signs of different disease stages. The algorithm and key points of differential diagnosis are indicated. Special attention was given to the patients’ management: pathogenetic treatment and rehabilitation of pediatric patients.Мышечная дистрофия Дюшенна — одна из наиболее частых форм мышечных дистрофий детского возраста. По разным источникам, заболеваемость миодистрофией Дюшенна оценивается как 1 на 3,5–6 тыс. новорожденных мальчиков. В основе заболевания лежит мутация гена DMD, кодирующего белок дистрофин, приводящая к отсутствию или недостаточной функции дистрофина. Заболевание характеризуется слабостью проксимальных и псевдогипертрофией икроножных мышц, и в среднем к 11 годам пациенты теряют возможность самостоятельно передвигаться и становятся неамбулаторными больными. Авторами представлены современные эпидемиологические данные и особенности этиопатогенеза мышечной дистрофии Дюшенна, описаны клинические характеристики разных стадий болезни. Подробно представлен алгоритм и указаны ключевые этапы дифференциально-диагностического поиска. Особое внимание уделено вопросам лечения пациентов, в том числе патогенетическому лечению, реабилитации пациентов детского возраста

    Measurement of charged jet suppression in Pb-Pb collisions at √sNN = 2.76 TeV

    A measurement of the transverse momentum spectra of jets in Pb-Pb collisions at sNN−−−√=2.76 TeV is reported. Jets are reconstructed from charged particles using the anti-kT jet algorithm with jet resolution parameters R of 0.2 and 0.3 in pseudo-rapidity |η|<0.5. The transverse momentum pT of charged particles is measured down to 0.15 GeV/c which gives access to the low pT fragments of the jet. Jets found in heavy-ion collisions are corrected event-by-event for average background density and on an inclusive basis (via unfolding) for residual background fluctuations and detector effects. A strong suppression of jet production in central events with respect to peripheral events is observed. The suppression is found to be similar to the suppression of charged hadrons, which suggests that substantial energy is radiated at angles larger than the jet resolution parameter R=0.3 considered in the analysis. The fragmentation bias introduced by selecting jets with a high pT leading particle, which rejects jets with a soft fragmentation pattern, has a similar effect on the jet yield for central and peripheral events. The ratio of jet spectra with R=0.2 and R=0.3 is found to be similar in Pb-Pb and simulated PYTHIA pp events, indicating no strong broadening of the radial jet structure in the reconstructed jets with R<0.3.

    Beauty production in pp collisions at √s=2.76 TeV measured via semi-electronic decays

    The ALICE Collaboration at the LHC reports measurement of the inclusive production cross section of electrons from semi-leptonic decays of beauty hadrons with rapidity |y| < 0.8 and transverse momentum 1 < pT < 10 GeV/c, in pp collisions at √s = 2.76 TeV. Electrons not originating from semi-electronic decay of beauty hadrons are suppressed using the impact parameter of the corresponding tracks. The production cross section of beauty decay electrons is compared to the result obtained with an alternative method which uses the distribution of the azimuthal angle between heavy-flavour decay electrons and charged hadrons. Perturbative QCD predictions agree with the measured cross section within the experimental and theoretical uncertainties. The integrated visible cross section, σb→e = 3.47 ± 0.40(stat) +1.12 −1.33(sys) ± 0.07(norm) μb, was extrapolated to full phase space using Fixed Order plus Next-to-Leading Log (FONLL) calculations to obtain the total bb production ¯ cross section, σbb¯ = 130 ± 15.1(stat) +42.1 −49.8(sys) +3.4 −3.1(extr) ± 2.5(norm) ± 4.4(BR) μb
