Accident prediction models for unsignalized intersections
Creators: name: Rodríguez, Luis F.  (Luis Felipe)
Publisher: name: University of British Columbia
Year: 2009

description: The main objective of this thesis is to develop Accident Prediction Models (APM) for estimating the safety potential of urban unsignalized (T and 4-leg) intersections in the Greater Vancouver Regional District (GVRD) and Vancouver Island on the basis of their traffic characteristics. The models are developed using the generalized linear regression modeling (GLIM) approach, which addresses and overcomes the shortcomings associated with the conventional linear regression approach. The safety predictions obtained from GLIM models can be refined using the Empirical Bayes' approach to provide, more accurate, site-specific safety estimates. The use of the complementary Empirical Bayes approach can significantly reduce the regression to the mean bias that is inherent in observed accident counts. The thesis made use of sample accident and traffic volume data corresponding to unsignalized (both T and 4-leg) intersections located in urban areas of the Greater Vancouver Regional District (GVRD) and Vancouver Island. The data included a total of 427 intersections located in the cities of Victoria, Surrey, Nanaimo, Coquitlam, Burnaby and Vancouver. The information available for each intersection included the total number of accidents in the 1993-1995 period, traffic volumes for both major and minor roads given in Average Annual Daily Traffic (AADT) and type of intersection (T or 4-leg). Four categories of models were developed in this study: (1) models for the total number of accidents; (2) separate models for T and 4-leg intersections; (3) separate models for different regions (Vancouver Island, the Lower Mainland and Surrey); and (4) a model for Surrey including intersection control. Five applications of APM were used in this thesis. Four of them relate to the use of the Empirical Bayes refinement: identification of accident-prone locations, developing critical accident frequency curves, ranking the identified accident-prone locations and before and after safety evaluation. The fifth application provides a safety-planning example, comparing the safety of a 4-leg intersection to two staggered T-intersections. These applications show the importance of implementing APM as a tool to assess in a reliable fashion traffic safety, and design different safety strategies.

description: Η αδήριτη ανάγκη για αλλαγή και η αποτυχία των μέχρι τώρα επιχειρούμενων μεταρρυθμίσεων οδηγούν τις εκπαιδευτικές κοινότητες στην πολιτική της αποσπασματικής αλλαγής μέσω της εισαγωγής κοινοτομιών στη σχολική μονάδα. Τα πλεονεκτήματα τους, όπως η ευελιξία, το χαμηλό κόστος και η ανταπόκριση στις πραγματικές ανάγκες του σχολείου, τις καθιστούν ως το αποτελεσματικότερο μέσο για τη βελτίωση της σχολικής μονάδας. Τα προβλήματα που παρουσιάζονται σε όλη τη διάρκεια της εισαγωγής καινοτομιών (υιοθέτηση, εφαρμογή, θεσμοθέτηση) δεν είναι αξεπέραστα, αρκεί ο διευθυντής της σχολικής μονάδας, υιοθετόντας τα χαρακτηριστικά ενός μετασχηματιστικού ηγέτη, να τα επιλύσει. Μέσα σε αυτό το πλαίσιο, η έρευνα της παρούσης εργασίας αξιοποιώντας το υλικό των συνεντεύξεων 10 διευθυντών Γυμνασίων και Γενικών Λυκείων του Νομού Καβάλας και των ερωτηματολογίων των εκπαιδευτικών αναδδεικνύει τον ηγετικό και καθοριστικό ρόλο του διευθυντή στην επιτυχή ή αποτυχή έκβαση των καινοτομιών.
description: The necessity of school change and the failure of the realized reforms force the education to adopt the policy of school's innovations. Their advantages, such as flexibility, low coste and respond to the real needs of school, make them the most valiable instrument of school change. The problems, that appear during the hall procedure, can be solved by the school's principal, in case of he adopts the characteristics of transformational leadership. In these context, this research, using the interviews of 10 high school's principal (in the prefecture of Kavala) and the questionnaires of theirs teachers, shows the importance and the meaning of principal's role in the procedure of school's innovations.

description: Σύμφωνα με την υπάρχουσα βιβλιογραφία το κλίμα της Γης μεταβάλλεται και πλέον η υπερθέρμανση του πλανήτη είναι αισθητή και επιβεβαιωμένη σε πολλές περιοχές. Οι αιτίες του φαινόμενου είναι πολλές, αφενός η ανθρωπογενής παρέμβαση μέσω της αύξησης των αερίων του θερμοκηπίου, και αφετέρου η εξέλιξη και η αλλαγή των φυσικών παραγόντων μεταβολής του κλίματος.Στην παρούσα εργασία σκοπό είχαμε να εξετάσουμε τις κλιματικές τάσεις μετεωρολογίας και τη μεταβλητότητα του κλίματος στην Ελλάδα και στην Ευρώπη κατά την περίοδο 1958-2001, αλλά και κατά τις δύο υποπεριόδους 1958-1979 και 1980-2001. Συγκεκριμένα εξετάστηκε η επίδραση φυσικών παραγόντων μεταβολής, όπως η ηλιακή δραστηριότητα και η ταλάντωση του βόρειου Ατλαντικού (North Atlantic Oscillation (NAO)), χρησιμοποιώντας δεδομένα των αναλύσεων παρατήρησης ERA-40 του European Centre for Medium-Range Weather Forecasts (ECMWF). Αυτό που τελικά διαπιστώσαμε είναι τάσεις θέρμανσης σε ένα μεγάλο κομμάτι της Ευρώπης, που οφείλεται σε μεγάλο ποσοστό στην επίδραση της ΝΑΟ, ενώ τα αποτελέσματα της επίδρασης της ηλιακής δραστηριότητας δεν είναι τόσο έντονα και χρειάζεται περισσότερη έρευνα στο συγκεκριμένο τομέα.
description: According to the existing bibliography, the climate of Earth is being altered and henceforth the overheat of our planet is acknowledgeable and confirmed in a lot of regions. This phenomenon has been caused not only by the increase of greenhouse gases due to human intervention, but also by the development and the change of natural factors of climate change. The basic goal of this work is to examine the climatic tendencies of meteorology and the variability of climate in Greece and in Europe during the period 1958 to 2001, and at the same time during the two sub-periods: 1958-1979 and 1980-2001. We have specifically examined the effect of natural factors of change such as the solar activity and the North Atlantic Oscillation (NAO), using ERA-40 observation data analysis by the European Centre for Medium-Range Weather Forecasts (ECMWF). Finally, we have concluded that there are tendencies of an increase in temperature in a large part of Europe, which is owned to the large effect of NAO, while the effect of the solar activity is not so much intense. However, more research is needed in this particular field.

description: At very high laser intensities, achieved with modern, diode-pumped solid state lasers having high beam quality and high pulse power, even transparent materials such as glass can be easily machined with high efficiency and precision. Examples are given by the subsurface engraving, the cutting and the drilling of glass, where the physical effect of nonlinear absorption in transparent media is used. This enables machining processes and results which are not feasible with any other tool known before.

description: Due to differenees in thermal expansion, crazing and delamination effects are observed in multiphase materials such as glasspolymer composites. For a composite consisting of spherical particles homogeneously embedded in a matrix phase, the radial and tangential stresses occurring have been simulated. Two-dimensional calculations were used as a basis for optimizing the optical transparency of the material which was found to be strongly affected by the mechanical properties of the constituents of the composite and the resulting stresses. Further, the influence of the shape and the size distribution of the particles on the emergence of scattering surfaces inside the material is described. With the Christiansen-Shelyubskii method the maximum transparency of a potential material depending on whether it is a gradient material or not can be predicted.

description: Corporate Social Responsibility (CSR) is a business approach that contributes to sustainable development by delivering economic, social and environmental benefits to all stakeholders. The effect of corporate social responsibilities of a business on their financial performance has been a subject of intense argument and its empirical analysis result shows inconsistent findings. This study aims to examine the effects of CSR and the financial performance of Ethiopian leather industries. A theoretical framework is proposed based on a stakeholder approach by defining five stakeholders (i.e., employee, customer, supplier, community & environment) and taken as the independent variables. This study uses a questionnaire survey for the measurement of CSR and a three consecutive (2014–2016) years’ average return on the asset enables us to measure firms’ financial performance data, analyzed using a multiple regression models. Finally, this study reveals that a statistically significant positive effect of employee CSR, supplier CSR, environment CSR and aggregate CSR on financial performance whereas customer and community CSR factors are negatively related to return on asset

Πραγματοποιήθηκαν 3 μετρήσεις: πριν την παρέμβαση, μετά το τέλος της και τρεις μήνες μετά για τον έλεγχο διατήρησης των αποτελεσμάτων. Όλες οι κλίμακες είχαν υψηλό βαθμό εσωτερικής συνοχής (α>.66). Από την ανάλυση διακύμανσης με επαναλαμβανόμενες μετρήσεις φάνηκε ότι δεν υπήρχαν διαφορές ανάμεσα στους μέσους όρους των ομάδων αξιολογημένων στις 3 χρονικές στιγμές.
description: The purpose of the present study was to examine the influences of physical exercise, aesthetic interference and their combination on a series of dependent variables: body cathexis, general self-esteem, perceived sport competence, physical condition, body attractiveness, physical strength and physical self-worth. Eighth (80) women aged 18-35 (average = 23.61 years old) classified in 4 groups of 20 (twenty) individuals each participated in the research: a] the control target group who accepted no interference, b] the first sample group who physically exercised, c] the second sample group who underwent facial make-up and d] the third sample group who underwent physical exercise and make-up. Three (3) estimations took place: one prior to the interference, one after its completion and the final three months later for the checking of the maintenance of the results. The internal consistency of subscales was at an acceptable level (a > .66). The results deriving from the analysis of repeated measurements showed that there weren't differences among the averages of the groups evaluated at the three time moments.

description: Glasses from the Na2o-B2O3-SiO2 system, doped with AI2O3, ZrO2 and TiO2, were thermally (in the temperature range of 420 to 700 °C) and chemieally treated. During thermal treatment, separation of the borate phase from the silica skeleton occurrred resulting in the formation of an interconnected microstructure. The borates were in the form of small drops joined to each other. In the course of chemical treatment the borates were leached in water and water solutions of acids or bases with the glass becoming very porous. The experiments showed that ZrO2 and TiO2 caused an increase in pore diameter at defmite leaching times. AI2O3, however, decreased it, so that glasses doped with AI2O3 have a greater specific surface. In this case a double-pore distribution occurred. Porous glasses may find application in many branches of science and engineering. The applications depend on the internal arrangement, size and shape of pores. These parameters may be in a wide range modified by a change of the chemical composition. Testing structure and properties of microporous glasses from the system Na2O-B2O3-SiO2 with different additions was the main aim of this work. The following testing methods were applied: DTA, XRD, TEM, infrared spectroscopy and sorption porosimetry.

description: Synthesis of new materials that can host magnetic skyrmions and their thorough experimental and theoretical characterization are essential for future technological applications. The $β$-Mn-type compound FePtMo$_3$N is one such novel material that belongs to the chiral space group $P4_132$, where the antisymmetric Dzyaloshinkii-Moriya interaction is allowed due to the absence of inversion symmetry. We report the results of small-angle neutron scattering (SANS) measurements of FePtMo$_3$N and demonstrate that its magnetic ground state is a long-period spin helix with a Curie temperature of 222~K. The magnetic field-induced redistribution of the SANS intensity showed that the helical structure transforms to a lattice of skyrmions at $\sim$13~mT at temperatures just below $T_{\text C}$. Our key observation is that the skyrmion state in FePtMo$_3$N is robust against field cooling down to the lowest temperatures. Moreover, once the metastable state is prepared by field cooling, the skyrmion lattice exists even in zero field. Furthermore, we show that the skyrmion size in FePtMo$_3$N exhibits high sensitivity to the sample temperature and can be continuously tuned between 120 and 210~nm. This offers new prospects in the control of topological properties of chiral magnets.

description: Natural glass is a well-known phenomenon found in different geological formations on both the earth and the lunar surface. This demonstrates that the vitreous state has been resistant to change on these surfaces for more than a hundred million years. Glass formation is determined by magmatic, metamorphic and sedimentary processes. The quantities of naturally produced glass vary between 10^-6 and 10^9 g, and the occurrence is given in microscopie glassy inclusions as well as in 'glassy mountains'. The chemical composition of natural glass is mainly rhyolitic and peraluminous. Industrially produced glass usually contains less AI2O3 (< 10 wt%) than glass found in its natural state. The transformation of the glassy state occurs in different processes (in many cases at constant volume): crystallization ('devitrification'), solution (corrosion), or hydratization and pallagonitization. By these processes, glass is transformed into sheet silicates, zeolithes, feldspars etc. and amorphous gels of silicon, iron, manganese etc. Natural glass has been under consideration for use as a suitable material for isolating complex and dangerous wastes. To help solve problems of waste management particular to industrial production, and to achieve a greater productive use of natural glass resources, glass scientists and engineers as well as geoscientists will have to cooperate in the future.

description: We propose a quantum absorption refrigerator using the quantum physics of resonant tunneling through quantum dots. The cold and hot reservoirs are fermionic leads, tunnel coupled via quantum dots to a central fermionic cavity, and we propose configurations in which the heat absorbed from the (very hot) central cavity is used as a resource to selectively transfer heat from the cold reservoir on the left, to the hot reservoir on the right. The heat transport in the device is particle---hole symmetric; we find two regimes of cooling as a function of the energy of the dots---symmetric with respect to the Fermi energy of the reservoirs---and we associate them to heat transfer by electrons above the Fermi level, and holes below the Fermi level, respectively. We also discuss optimizing the cooling effect by fine-tuning the energy of the dots as well as their linewidth, and characterize regimes where the transport is thermodynamically reversible such that Carnot Coefficent of Performance is achieved with zero cooling power delivered.

description: We study the optimal design of switching measurements of small Josephson junction circuits which operate in the macroscopic quantum tunnelling regime. Starting from the D-optimality criterion we derive the optimal design for the estimation of the unknown parameters of the underlying Gumbel type distribution. As a practical method for the measurements, we propose a sequential design that combines heuristic search for initial estimates and maximum likelihood estimation. The presented design has immediate applications in the area of superconducting electronics implying faster data acquisition. The presented experimental results confirm the usefulness of the method.

description: Α study on viscosity and flow behavior of dried water glasses using an extrusion method is first reported. The rheological properties of water glass samples with water concentrations in the range from 22.2 to 36.4 wt% and also some glycerin-containing samples were studied. The extrusion method used enables the determination of viscosities in the range from 10^7 to 10^10 dPa s. By comparison to glass melts, relatively low temperatures in the range from 50 to 85 °C are used. During extrusion of dried water glasses, the viscosity decreases significantly with increasing shear rate. Lower water concentrations lead to a more pronounced deviation from Newtonian flow behavior. This is attributed to nonlinear flow behavior rather than to localized viscous heating effects by mechanical deformation work. Furthermore, the effect of composition on the viscosity-temperature dependence is studied. The higher the water concentration, the lower is the viscosity. Glycerin additions intensify this effect. Generally, the viscosity decreases with increasing temperature. Vogel-Fulcher-Tammann parameters are obtained by ftting the data of extrusion experiments and the corresponding Tg values.

Over a wide temperature range, the measured peak potentials decreased linearly with temperature. The peak potentials are most negative for the 15Na2O - 85SiO2 melt and least negative for the 16Na2O - 10MgO - 74SiO2 melt. The effect of the glass composition on the Sn2+/Sn4+ redox equilibrium is much less pronounced than in the case of the Fe2+/Fe3+ equilibrium.

description: We revisit the problem of an elastic line (e.g. a vortex line in a superconductor) subject to both columnar disorder and point disorder in dimension $d=1+1$. Upon applying a transverse field, a delocalization transition is expected, beyond which the line is tilted macroscopically. We investigate this transition in the fixed tilt angle ensemble and within a one-way model where backward jumps are neglected. From recent results about directed polymers and their connections to random matrix theory, we find that for a single line and a single strong defect this transition in presence of point disorder coincides with the Baik-Ben Arous-Peche (BBP) transition for the appearance of outliers in the spectrum of a perturbed random matrix in the GUE. This transition is conveniently described in the polymer picture by a variational calculation. In the delocalized phase, the ground state energy exhibits Tracy-Widom fluctuations. In the localized phase we show, using the variational calculation, that the fluctuations of the occupation length along the columnar defect are described by $f_{KPZ}$, a distribution which appears ubiquitously in the Kardar-Parisi-Zhang universality class. We then consider a smooth density of columnar defect energies. Depending on how this density vanishes at its lower edge we find either (i) a delocalized phase only (ii) a localized phase with a delocalization transition. We analyze this transition which is an infinite-rank extension of the BBP transition. The fluctuations of the ground state energy of a single elastic line in the localized phase (for fixed columnar defect energies) are described by a Fredholm determinant based on a new kernel. The case of many columns and many non-intersecting lines, relevant for the study of the Bose glass phase, is also analyzed. The ground state energy is obtained using free probability and the Burgers equation.

description: Soil aggregation is the process by which aggregates of different sizes arejoined and held together by different organic and inorganic materials. Thereare several models of aggregation. Aggregate stability is affected by soilprimary characteristics and by the management factors. There are twomethods of measuring aggregate stability: the method which analyze thebreakdown of aggregates due to the wetting action which refers to macroaggregateand the method which measures the water dispersible clay, whichrefers to both micro-aggregates and macro-aggregates. The purpose of thispaper is to examine, which aggregate class is less stable using waterdispersible clay as criterion and also examine which is the role of organicmatter and Fe and Al oxides. In conclusion clay, organic matter and Fe and Aloxides are the aggregation factors, the negative effect of liming was confirmedwhile the water dispersible clay was increased, the positive effect of organicsubstance and it was found that the bigger part of dispersible clay isoriginates from macro-aggregates.

description: A ballistic strip of graphene (width W>> length L) connecting two normal metal contacts is known to have a minimum conductivity of 4e^{2}/pi h at the Dirac point of charge neutrality. We calculate what happens if one of the two contacts becomes superconducting. While the ballistic conductance away from the Dirac point is increased by Andreev reflection at the normal-superconductor (NS) interface, we find that the minimum conductivity stays the same. This is explained as a manifestation of pseudo-diffusive conduction at the Dirac point. As a generalization of our results for a ballistic system, we provide a relation between the conductance G_NS of an arbitrarily disordered normal-superconductor junction in graphene and its value G_N when both contacts are in the normal state.

description: Corrosion of refractory silica brick used to line the crown of many glass-melting furnaces is a serious problem in furnaces using oxygen-fuel rather than air-fuel mixtures. To better understand and to quantify this process analytical models are utilized to evaluate the importance of four potential rate-limiting processes: a) gas-phase transport of NaOH to the crown surface; b) diffusion of sodium-containing reactants through a liquid product layer that forms on the brick face; c) gas-phase diffusion of NaOH into refractory pores; and d) chemical-kinetic limitations at the silica grain surface. Predictions are compared with reported corrosion rates and product compositions previously determined by post-mortem analysis of refractory samples. It is concluded that corrosion occurs largely by reaction and removal of material from the exposed brick face, rather than by transport of reactants into the porous bricks. The observed presence of corrosion products deep within the brick pores is shown to be consistent with capillary suction of high-viscosity liquid products from the hot face into the interior. The results further suggest that mechanisms (b) and (c) do not substantially limit the rate of corrosion, but that mechanisms (a) and (d) may both be important. Comparison of measurements with equilibrium predictions of corrosion-product composition indicate that the corrosion reactions are likely to be close to equilibrium at the conditions and lifetimes typical of full-scale furnaces, but that significant departures from equilibrium may occur in short-duration tests. Although computed corrosion rates based on mass transport through a gas boundary layer are somewhat greater than those observed, the results are very sensitive to the gas-phase concentration of NaOH and to the refractory temperature, both of which contain significant uncertainties.

description: In this paper, we investigate two major immunization strategies, random immunization and targeted immunization, of the susceptible-infected (SI) Model on the Barabási-Albert (BA) networks. For the heterogenous structure, the random strategy is quite ineffective if the vaccinated proportion is quite small, while the targeted one which prefers to vaccinate the individuals with the largest degree can sharply depress the epidemic spreading even only a small amount of population are vaccinated. The analytical solution is also obtained,which can capture the trend of velocity change versus the amount of vaccinated population.

This, in particular, provides a proof of the existence of a minimal model for a rank one foliation on a threefold for a wider range of singularities, after McQuillan.

description: We study chirality of the vorticity of the Universe within the Einstein-Cartan cosmology. The role of the spin of fermion species during the evolution of the Universe is studied by averaged spin densities and Einstein-Cartan equations. It is shown that spin density of the light Majorana neutrinos acts as a seed for vorticity at early stages of the evolution of the Universe. Its chirality can be evaluated in the vicinity of the spacelike infinity. It turns out that vorticity of the Universe has right-handed chirality.

description: Osumilite-type phases, which have high temperature stability and low linear thermal expansion coefficients, were crystallized from modified basalt glass composition. To satisfy the compositional requirements of osumilite molecules, a deliberate amount of kaolin, sand, magnesite and TiO2 should be added to the basalt. The crystallization process was investigated by DTA, X-ray diffractometry and SEM. The effect of compositional changes on bulk crystallization and growth morphology was also studied. The linear thermal expansion coefficient was measured to characterize the produced glass-ceramics.

microbunching

description: The micro-bunching instability is a longitudinal instability that leads to dynamical deformations of the charge distribution in the longitudinal phase space. It affects the longitudinal charge distribution, and thus the emitted coherent synchrotron radiation spectra, as well as the energy distribution of the electron bunch. Not only the threshold in the bunch current above which the instability occurs, but also the dynamics above the instability threshold strongly depends on machine parameters, e.g. accelerating voltage, momentum compaction factor, and beam energy. All this makes the understanding and potential mitigation or control of the micro-bunching instability an important topic for the next generation of light sources and circular e+e− colliders. This contribution will give an overview of the micro-bunching instability and discuss how technological advances in the turn-by-turn and bunch-by-bunch diagnostics are leading to a deeper understanding of this intriguing phenomenon.

description: The giant magnons are classical solitons of the O(N) sigma-model, which play an important role in the AdS/CFT correspondence. We study quantum giant magnons first at large N and then exactly using Bethe Ansatz, where giant magnons can be interpreted as holes in the Fermi sea. We also identify a solvable limit of Bethe Ansatz in which it describes a weakly-interacting Bose gas at zero temperature. The examples include the O(N) model at large N, weakly interacting non-linear Schrodinger model, and nearly isotropic XXZ spin chain in the magnetic field.

description: We examine the concurrence and entanglement entropy in quantum spin chains with random long-range couplings, spatially decaying with a power-law exponent $α$. Using the strong disorder renormalization group (SDRG) technique, we find by analytical solution of the master equation a strong disorder fixed point, characterized by a fixed point distribution of the couplings with a finite dynamical exponent, which describes the system consistently in the regime $α> 1/2$. A numerical implementation of the SDRG method yields a power law spatial decay of the average concurrence, which is also confirmed by exact numerical diagonalization. However, we find that the lowest-order SDRG approach is not sufficient to obtain the typical value of the concurrence. We therefore implement a correction scheme which allows us to obtain the leading order corrections to the random singlet state. This approach yields a power-law spatial decay of the typical value of the concurrence, which we derive both by a numerical implementation of the corrections and by analytics. Next, using numerical SDRG, the entanglement entropy (EE) is found to be logarithmically enhanced for all $α$, corresponding to a critical behavior with an effective central charge $c = {\rm ln} 2$, independent of $α$. This is confirmed by an analytical derivation. Using numerical exact diagonalization (ED), we confirm the logarithmic enhancement of the EE and a weak dependence on $α$. For a wide range of distances $l$, the EE fits a critical behavior with a central charge close to $c=1$, which is the same as for the clean Haldane-Shastry model with a power-la-decaying interaction with $α=2$. Consistent with this observation, we find using ED that the concurrence shows power law decay, albeit with smaller power exponents than obtained by SDRG.

description: Control of glass flow in a glass tank is a key technology in the glass melting process. The flow and temperature distributions of the glass melt greatly affect the quality of glass products. However, these phenomena have not been well understood due to the difficulty involved in the measurement as a result of the high temperature of the glass melt. Α small melting furnace was developed that was heated by electrodes. The glass flow was measured and analyzed by 3-D computer simulation. The numerical results show good agreement with the experimentally measured values. It is shown that it is possible to control the glass convection using a variety of the electric boosting conditions, the heat loss through walls and the charged glass batch. The quality of glass melt was evaluated by analyzing the temperature histories of virtual particles the furnace was charged with. It is found that the temperature of the particles is high and stable near the throat, as shown by the experimental data.

description: Cyber-Physical Systems (CPS) play a crucial role in the era of the 4thIndustrial Revolution. Recently, the application of the CPS to industrial manufacturing leads to a specialization of them referred as Cyber-Physical Production Systems (CPPS). Among other challenges, CPS and CPPS should be able to address interoperability issues, since one of their intrinsic requirement is the capability to interface and cooperate with other systems. On the other hand, to fully realize theIndustry 4.0 vision, it is required to address horizontal, vertical, and end-to-end integration enabling a complete awareness through the entire supply chain. In this context, Semantic Web standards and technologies may have a promising role to represent manufacturing knowledge in a machine-interpretable way for enabling communications among heterogeneous Industrial assets. This paper proposes an integration of Semantic Web models available at state of the art for implementing a5C architecture mainly targeted to collect and process semantic data stream in a way that would unlock the potentiality of data yield in a smart manufacturing environment. The analysis of key industrial ontologies and semantic technologies allows us to instantiate an example scenario for monitoring Overall Equipment Effectiveness(OEE). The solution uses the SOSA ontology for representing the semantic datastream. Then, C-SPARQL queries are defined for periodically carrying out useful KPIs to address the proposed aim.

Amber chromophore formation in sulphur- and iron-containing soda-lime-silica glasses
Creators: name: Beerkens, Ruud G. C.
Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 2003
Subjects: subject: 660

description: During cooling of reduced soda-lime-silica glass melts, doped with iron oxides and sulphur species, ferrous iron (Fe2+) reacts with sulphite (SO3 2-), and the Fe3+ (ferric iron) and also the S2- (sulphide) concentration will increase. The sulphite concentration in the amber glass melt after fining is sufficient to produce ferric iron and sulphide, required for amber chromophore formation during the cooling process. The product of the concentrations of Fe3+ and sulphide will strongly increase during coohng below about 1000 K. This mechanism implies that a necessary condition for amber formation is the availability of sufficiently large iron concentrations in the presence of a sufficient sulphite content in the high-temperature glass melt. The formation of a chromophore, based on Fe3+ - S2- - 3O2- - nNa+ complexes in the silicate glass will lead to amber colouring. Α strong dependency of the amber intensity of the glass on the maximum temperature of melting, the alkali concentration of the glass, the total iron concentration and on the oxidation-state of the melt has been found experimentally. The charge of the networkmodifying alkali ions stabilizes the ferric iron-sulphide-oxide-alkali chromophores. In strongly reduced melts, hardly any sulphite can be formed and during cooling, the amber chromophore formation is limited. Experiments show a decrease in ferric iron concentrations and in the amber intensity when over-reducing glasses. Α decrease in the amber intensity of amber glasses with increasing water content is probably caused by lower sulphite retention after fining of waterrich melts.
