description: This study contributes to the identification of coupled THM constitutive model parameters via back analysis against information-rich experiments. A sampling based back analysis approach is proposed comprising both the model parameter identification and the assessment of the reliability of identified model parameters. The results obtained in the context of buffer elements indicate that sensitive parameter estimates generally obey the normal distribution. According to the sensitivity of the parameters and the probability distribution of the samples we can provide confidence intervals for the estimated parameters and thus allow a qualitative estimation on the identified parameters which are in future work used as inputs for prognosis computations of buffer elements. These elements play e.g. an important role in the design of nuclear waste repositories.

description: ABSTRACT Digital marketing changes the way companies sell their products. Managers of B2B companies are looking for answers how to deploy digital marketing strategies to boost their sales success. There is scarce research on most suitable online promotional techniques with regard to the B2B segment therefore this thesis should provide an additional view on the topic. The theoretical part aims to understand digital marketing, sales success and B2B specifics. The second part focuses on the following research questions: To understand the usage of online marketing strategies influence the success of B2B companies? What are the main goals that companies should strive to achieve in order to ensure success? What are key online marketing strategies for achieving the goals that lead to success? To understand the appropriate usage of online marketing ensure the success of B2B companies? A mixture of explorative and qualitative approach was used. The methodology for addressing the research questions varied from explaining key concepts, reviewing relevant literature and getting empirical interview data. The analysis is based on semi-structured interviews with marketing agency decision makers, marketing professionals, B2B marketing strategists and senior sales managers in the geographical region of Slovenia and Austria. Key contributions of the thesis can be summed up with the following facts: Majority strongly agrees that digital marketing positively affects the success of B2B companies, Referrals and content marketing positively affect the revenue of B2B companies, Income generation and customer value are the most important company goals, Good corporate website, social media and SEO are crucial, The biggest budget share is allocated to digital advertising.

description: (1) Understanding the effects of manufacturing factors on microbial adhesion is essential for optimizing additive denture base materials and improving their clinical performance. This study evaluated how polymerization time, layer thickness, extended cleaning, and storage conditions influence C. albicans and S. mutans adhesion on a denture base material. (2) Specimens (n = 15/group, d = 8 mm, h = 2 mm) were additively fabricated or poured (reference). Digital light processing was performed with varying polymerization times, layer thicknesses, extended cleaning, and storage. Microbial adhesion was assessed using a luminescence assay. Surface properties were characterized by roughness (Sa/Sz), hardness, and surface free energy (SFE). Statistics: The Shapiro–Wilk test, ANOVA, Bonferroni post hoc test, and Pearson correlation (α = 0.05) were utilized. (3) Polymerization time, layer thickness, cleaning, and storage conditions significantly influenced C. albicans and S. mutans adhesion. Increased layer thickness reduced C. albicans adhesion but promoted S. mutans colonization, emphasizing the role of SFE. Extended polymerization and optimized cleaning reduced microbial adhesion, highlighting the need for tailored processing to enhance microbial resistance and material integrity. (4) Manufacturing factors influenced microbial adhesion, with additive materials reducing the abundance of C. albicans but increasing the abundance of S. mutans, underscoring the importance of material adjustments and extended polymerization to enhance microbial resistance.

description: Η αλματώδης πρόοδος της τεχνολογίας τις τελευταίες δεκαετίες, έχουν οδηγήσει στη γέννηση ενός νέου είδους πολέμου, τον κυβερνοπόλεμο. Παράλληλα, οι θεωρητικοί του δικαίου προσπαθούν να «χαρτογραφήσουν» τη νέα αυτή μορφή πολέμου. Τα κύρια χαρακτηριστικά του κυβερνοπολέμου είναι η έλλειψη ορίων όσον αφορά το μέγεθος των επιχειρήσεων, η ταχύτητα διεξαγωγής τους, η υπέρβαση της έννοιας των δικαιοδοσιών λόγω του παγκόσμιου χαρακτήρα του Διαδικτύου, ο υψηλός βαθμός μεταβλητότητάς του, η δυσκολία καταλογισμού των επιθέσεων, η έλλειψη άμεσων απωλειών, σε αντίθεση με τον «παραδοσιακό» πόλεμο, το χαμηλό οικονομικό κόστος διεξαγωγής του και το δυσανάλογο κόστος προστασίας του αμυνόμενου και η αδυναμία πρόβλεψης των επιθέσεων. Οι κυριότερες μορφές διεξαγωγής του κυβερνοπολέμου είναι η κυβερνο-κατασκοπεία, η διάδοση προπαγάνδας, οι κατανεμημένες επιθέσεις άρνησης εξυπηρέτησης (distributed denial of service attacks), οι επιθέσεις κατά οργανισμών κοινής ωφέλειας και υποδομών και η διανομή παραβιασμένου τεχνολογικού υλικού. Ο κυβερνοπόλεμος, ως μορφή διεξαγωγής πολέμου, υπάγεται στο Δίκαιο των Ενόπλων Συγκρούσεων, συνεπώς οι κυβερνοεπιχειρήσεις θα πρέπει να διεξάγονται με βάση τις βασικές αρχές του, οι οποίες διασφαλίζουν την (όσο είναι δυνατό) ομαλή και αναίμακτη διεξαγωγή τους. Η κυριότερη συζήτηση γύρω από τον κυβερνοπόλεμο περιστρέφεται γύρω από τη νομιμότητά του ως μέσο επίθεσης και αντεπίθεσης. Οι στόχοι των κυβερνοεπιχειρήσεων θα πρέπει να επιλέγονται με γνώμονα το Δίκαιο των Ενόπλων Συγκρούσεων, φροντίζοντας να διασφαλίζεται η ακεραιότητα των πολιτικών υποδομών.

Year: 2015

description: Flow-type landslides are typically triggered by heavy rainfalls and may cause large losses. Landslide risk may be rationally evaluated and mitigated with probabilistic approaches. In this paper, physical vulnerability of reinforced concrete buildings to landslides is assessed. Fragility analysis was carried out by assuming flow velocity as intensity measure, several damage states, and different mechanical models for beams, columns and masonry infill walls. Uncertainties in landslide impact loading, material properties, members geometry, and capacity models were taken into account. Both earthquake-resistant and gravity-load designed buildings were assessed as being representative of two low-rise building subclasses. Analysis results show that landslide fragility significantly depends on the presence and type of infill walls, which influence both out-of-plane and in-plane failure modes as well as yielding and failure of plastic hinges in columns.

description: Low-skilled labor makes a significant part of the construction sector, performing daily production tasks that do not require specific technical knowledge or confirmed skills. Today, construction market demands increasing skill levels. Many jobs that were once considered to be undertaken by low or un-skilled labor, now demand some kind of formal skills. The jobs that require low skilled labor are continually decreasing due to technological advancement and globalization. Jobs that previously required little or no training now require skilful people to perform the tasks appropriately. The study aims at ameliorating employability of less skilled manpower by finding ways to instruct them for performing constructions tasks. A review of exiting task instruction methodologies in construction and the underlying gaps within them warrants an appropriate way to train and instruct low skilled workers for the tasks in construction. The idea is to ensure the required quality of construction with technological and didactic aids seeming particularly purposeful to prepare potential workers for the tasks in construction without exposing them to existing communication barriers. A BIM based technology is considered promising along with the integration of visual directives/animations to elaborate the construction tasks scheduled to be carried on site.

description: Το διαδίκτυο αποτελεί σημαντικό εργαλείο για τους καταναλωτές και τις επιχειρήσεις, ενώ ο όγκος δεδομένων που παράγεται από τις αναζητήσεις χρηστών σε μηχανές αναζήτησης, όπως το Google, είναι τεράστιος και ανεκτίμητος. Οι αναζητήσεις αυτές αποτελούν πολύτιμη πηγή δεδομένων, τα οποία μπορούν να αξιοποιηθούν για την εξαγωγή πληροφοριών και την ανάλυση της καταναλωτικής συμπεριφοράς. Η παρούσα διπλωματική εργασία επικεντρώνεται στην ανάλυση των δεδομένων της τουριστικής κίνησης στην Ελλάδα, εστιάζοντας στη συσχέτιση των αναζητήσεων στο Google με τα πραγματικά έσοδα που καταγράφονται από το ελληνικό κράτος. Στόχος της έρευνας είναι να εξεταστεί εάν τα δεδομένα αναζητήσεων από την πλατφόρμα του Google Trends μπορούν να αξιοποιηθούν για τη δημιουργία ενός μοντέλου που θα προβλέπει με ακρίβεια τα τουριστικά έσοδα της χώρας. Η ανάλυση περιλαμβάνει τη διερεύνηση της σχέσης ανάμεσα στις αναζητήσεις και τα συνολικά τουριστικά έσοδα. Για τον σκοπό αυτό, χρησιμοποιήθηκε η Παραγοντική Ανάλυση για τη σύνθεση των δεδομένων αναζητήσεων σε έναν ενιαίο δείκτη, τον Δείκτη Ζήτησης Τουρισμού ( Tourism Demand Index). Ο δείκτης αυτός αντιπροσωπεύει τη συνολική ελκυστικότητα της Ελλάδας ως τουριστικού προορισμού, όπως αποτυπώνεται μέσα από τις σχετικές αναζητήσεις στο διαδίκτυο. Στη συνέχεια, διερευνήθηκε η συσχέτιση του δείκτη με τα πραγματικά τουριστικά έσοδα, με στόχο να αξιοποιηθεί ο δείκτης ως βασικός παράγοντας στην εκπαίδευση του μοντέλου πρόβλεψης για τα συνολικά έσοδα του τουριστικού τομέα. Η επεξεργασία των δεδομένων πραγματοποιείται μέσω των εργαλείων Power BI και Tableau, τα οποία επιτρέπουν την οπτικοποίηση των δεδομένων και την ανάδειξη των τάσεων που προκύπτουν. Επιπλέον, για τη διαμόρφωση του μοντέλου πρόβλεψης, εφαρμόστηκε τεχνική μηχανικής μάθησης μέσω του εργαλείου Orange Data Mining με τη χρήση νευρωνικών δικτύων, προκειμένου να προβλεφθούν τα μελλοντικά έσοδα με βάση τις διαδικτυακές αναζητήσεις. Από τη μελέτη αυτή προέκυψαν σημαντικά ευρήματα, καθώς αναδείχθηκε μια στατιστικά σημαντική συσχέτιση μεταξύ του Δείκτη Ζήτησης Τουρισμού και των πραγματικών εσόδων. Τα αποτελέσματα υποδεικνύουν ότι τα δεδομένα αναζητήσεων στο Google μπορούν να αποτελέσουν χρήσιμο εργαλείο για τη πρόβλεψη των εσόδων στον τομέα του τουρισμού, παρέχοντας στους φορείς του κλάδου τη δυνατότητα να προβαίνουν σε τεκμηριωμένες αποφάσεις και να βελτιώνουν τη στρατηγική τους

description: Resources are central to value creation processes. Hence, marketing and service research rely heavily on conceptualisations of resources and resource integration for theory building efforts. One of the most widely accepted marketing lenses on resources and resource integration is the service-dominant (S-D) logic. Depicting resources as becoming and contextual, S-D logic argues that their usefulness co-depends on other resources. Some assumptions of S-D logic have been challenged particularly its dichotomous categorisation of operand and operant resources. To inform ongoing S-D logic theorising, our article problematises the multiple and contradictory ontological views upon resources and resource integration present within S-D logic. Moving beyond critique, we propose concrete means for reconciling these contradictions. Seeing a parallel between S-D logic’s ontological inconsistencies and past ontological disagreements in the philosophy of science, we draw on the philosophical perspective of Karen Barad to develop a consistent onto-epistemological foundation for conceptualising the becoming nature of resources in S-D logic. The theory adaptation we perform enhances the applicability and explanatory capacity of S-D logic, while also offering a more robust and rigorous foundation for marketing and service research at large and giving managers new means to make sense of co-dependent resource phenomena.

description: In photogrammetry and computer vision the trifocal tensor is used to describe the geometric relation between projections of points in three views. In this paper we analyze the stability and accuracy of the metric trifocal tensor for calibrated cameras. Since a minimal parameterization of the metric trifocal tensor is challenging, the additional constraints of the interior orientation are applied to the well-known projective 6-point and 7-point algorithms for three images. The experimental results show that the linear 7-point algorithm fails for some noise-free degenerated cases, whereas the minimal 6-point algorithm seems to be competitive even with realistic noise.

description: Bicyclic boronates have recently emerged as promising candidates to invoke targeted biomolecular interactions, given their selectivity for specific functionalities. Despite this, the general stability of the C–B bond in vivo, for such heterocycles, remains an intractable challenge that can often preclude their utility in drug discovery. To address this challenge, de novo strategies that allow expedient access to strategically substituted boronates, that enable modulation of the C–B bond are urgently required. Herein we disclose an operationally simple, regioselective cross-coupling/cyclisation reaction of easily accessible vicinal boronic esters with 2-halophenols to rapidly forge 3-substituted bicyclic boronates. The utility of the platform was demonstrated via expedient access to Xeruborbactam derivatives, chemoselective manipulation of formed products and the convergent approach to bicyclic boronates with a pendent biomolecular probe.

description: This document describes some of the key output of training collaboration during the course of the PRACE-3IP project. The main focus is a report on the International HPC Summer School 2014, held on 1-6 June in Budapest, Hungary. The event is part of an annual series of summer schools jointly organised by PRACE and the Science and Engineering Discovery Environment (XSEDE) project from the U.S. since 2010. In the past couple of years, the collaboration has expanded to include new partners from Japan (RIKEN Advanced Institute for Computational Science) and from Canada (Compute/Calcul Canada). The 2014 school has attracted unprecedented levels of interest, where 534 applications were received from Canada, Europe, Japan and the U.S. for the 80 available places. The school was extremely successful in promoting knowledge of high performance computing and its applications in various scientific domains; an overwhelming proportion of participants have rated their experience at the school a success. The school has also encouraged friendships and collaborations among an international mix of participants and presenters from a wide range of backgrounds; a unique characteristic of the school that contributes to the learning experience and sets it apart from many other training events. Hence with the high level of interest from students, interest from new partners and steadily excellent reviews by participants, it is imperative that PRACE continues this collaboration in the future.
 Another focus of this document is to examine approaches to PRACE training collaboration. While some collaborative efforts in the past were conducted on an ad hoc basis (e.g. opportunistic co-location of events), others required more advanced planning and engagement (e.g. the International HPC Summer School series). It is recommended that future PRACE training will facilitate both types of collaborations by engaging with other partner organisations at the budget planning stage as well as providing a defined allocation of resources that can be committed on an ad hoc basis towards collaborative training events.

description: Recently, there is a growing interest in understanding how individuals adapt to changing climate conditions and climate-induced extreme weather events. An underexplored question is whether and how climate-related natural hazards affect household saving behavior. For this purpose, we exploit a natural experiment stemming from the European Flood of August 2002. Combining micro data with geo-coded flood maps allows us to analyze the causal impact of flood exposure on household savings within a differences-in-differences setting. We find that flood exposure depresses household saving behavior in the medium run. The most likely explanation is moral hazard induced by massive government support for affected households.

description: The Targeted Random Sampling (TRS) method is extended to moderate-to-high dimensional time invariant reliability analysis. TRS is an adaptive sampling method rooted in stratified sampling variance reduction technique and represents a specific algorithm for Refined Stratified Sampling. In this work, a Markov Chain is used to sample the space densely in the vicinity of the limit stat and multi-dimensional stratum division is proposed along with a neural network based approximation of the performance function. The method is shown to perform efficiently and accurately for estimation of probability of failure for a 20 dimensional problem.

description: An advanced probabilistic loading model is proposed in this paper to simulate the vehicles running along Ting Kau Bridge based on the weigh-in-motion system installed on the bridge. The weigh-in-motion system collects the information of vehicle speed, heading direction, lane used, axle weight, axle spacing between neighboring axles, etc. The data are employed to develop a statistical traffic load model which is able to incorporate the variation of daily traffic flow within different time intervals and the trend of the annual traffic flow as well as the statistical information. The time-dependent fatigue reliability assessment at critical locations can be carried out.

description: From the design experiences of arch dams in the past, it has significant practical value to carry out the shape optimization of arch dams, which can fully make use of material characteristics and reduce the cost of constructions. Suitable variables need to be chosen to formulate the objective function, e.g. to minimize the total volume of the arch dam. Additionally a series of constraints are derived and a reasonable and convenient penalty function has been formed, which can easily enforce the characteristics of constraints and optimal design. For the optimization method, a Genetic Algorithm is adopted to perform a global search. Simultaneously, ANSYS is used to do the mechanical analysis under the coupling of thermal and hydraulic loads. One of the constraints of the newly designed dam is to fulfill requirements on the structural safety. Therefore, a reliability analysis is applied to offer a good decision supporting for matters concerning predictions of both safety and service life of the arch dam. By this, the key factors which would influence the stability and safety of arch dam significantly can be acquired, and supply a good way to take preventive measures to prolong ate the service life of an arch dam and enhances the safety of structure.

description: The sizing of simple resonators like guitar strings or laser mirrors is directly connected to the wavelength and represents no complex optimisation problem. This is not the case with liquid-filled acoustic resonators of non-trivial geometries, where several masses and stiffnesses of the structure and the fluid have to fit together. This creates a scenario of many competing and interacting resonances varying in relative strength and frequency when design parameters change. Hence, the resonator design involves a parameter-tuning problem with many local optima. As its solution evolutionary algorithms (EA) coupled to a forced-harmonic FE simulation are presented. A new hybrid EA is proposed and compared to two state-of-theart EAs based on selected test problems. The motivating background is the search for better resonators suitable for sonofusion experiments where extreme states of matter are sought in collapsing cavitation bubbles.

Publisher: name: The University of British Columbia
Year: 2015

description: Large-scale fire tests are time intensive and expensive. Thus, usually only a limited number of test results are produced. In order to produce a more reliable description of the parameters of interest, the data set can be extended. This paper shows, as an example, how fire resistance tests investigating different parameters can be connected and further how censored test results can be considered in the evaluation of the results. The goal of the whole investigation is to extend the information of a limited number of fire tests in order to produce a more reliable description of the test results.

description: The paper introduces a systematic construction management approach, supporting expansion of a specified construction process, both automatically and semi-automatically. Throughout the whole design process, many requirements must be taken into account in order to fulfil demands defined by clients. In implementing those demands into a design concept up to the execution plan, constraints such as site conditions, building code, and legal framework are to be considered. However, complete information, which is needed to make a sound decision, is not yet acquired in the early phase. Decisions are traditionally taken based on experience and assumptions. Due to a vast number of appropriate available solutions, particularly in building projects, it is necessary to make those decisions traceable. This is important in order to be able to reconstruct considerations and assumptions taken, should there be any changes in the future project’s objectives. The research will be carried out by means of building information modelling, where rules deriving from standard logics of construction management knowledge will be applied. The knowledge comprises a comprehensive interaction amongst bidding process, cost-estimation, construction site preparation as well as specific project logistics – which are usually still separately considered. By means of these rules, favourable decision taking regarding prefabrication and in-situ implementation can be justified. Modifications depending on the available information within current design stage will consistently be traceable.

Lattices are the orbits of special type of crystallographic groups. For example, Penrose tilings can be obtained from a lattice tiling of E5, by the cut-and project method. Developing a mathematical theory of crystallographic tilings and generalising the method of canonical projection to other crystallographic groups than lattices. Using this method one can hope to construct (interesting), completely new types of aperiodic tilings.

description: This conceptual paper discusses opportunities and challenges towards the digital representation of structural health monitoring systems using the Industry Foundation Classes (IFC) standard. State-of-the-art sensor nodes, collecting structural and environmental data from civil infrastructure systems, are capable of processing and analyzing the data sets directly on-board the nodes. Structural health monitoring (SHM) based on sensor nodes that possess so called “on-chip intelligence” is, in this study, referred to as “intelligent SHM”, and the infrastructure system being equipped with an intelligent SHM system is referred to as “intelligent infrastructure”. Although intelligent SHM will continue to grow, it is not possible, on a well-defined formalism, to digitally represent information about sensors, about the overall SHM system, and about the monitoring strategies being implemented (“monitoring-related information”). Based on a review of available SHM regulations and guidelines as well as existing sensor models and sensor modeling languages, this conceptual paper investigates how to digitally represent monitoring-related information in a semantic model. With the Industry Foundation Classes, there exists an open standard for the digital representation of building information; however, it is not possible to represent monitoring-related information using the IFC object model. This paper proposes a conceptual approach for extending the current IFC object model in order to include monitoring-related information. Taking civil infrastructure systems as an illustrative example, it becomes possible to adequately represent, process, and exchange monitoring-related information throughout the whole life cycle of civil infrastructure systems, which is referred to as monitoring information modeling (MIM). However, since this paper is conceptual, additional research efforts are required to further investigate, implement, and validate the proposed concepts and methods.

title: ‘To See A World in a Grain of Sand’: The Glass of Nubia in the Meroitic Period and its Relationship to Glass of The Ancient Mediterranean World

description: Glass has been manufactured since the Bronze Age but ancient Nubian glassware has hitherto been little studied. Despite pioneering work in the field of archaeological science, scholarship has tended to analyse Nubian material culture from an Egyptocentric art historical or textual perspective, focusing on the perceived influence of Egypt over Nubia. This study uses chemical analysis to investigate the processes of glass manufacture in Nubia, studying artefacts from the Lower Nubian sites of Faras and Qasr Ibrim and Upper Nubian sites of Gabati and Meroe dating from the Meroitic Period (c.400BCE-400CE) and X-Group/Ballana Culture (c.400-600CE). This investigation moves beyond simple artefact reclassification by providing a new assessment of Nubian glass production from a materials science view point. The identification of the chemical makeup of glass allows the tracking of similar raw materials used throughout Nubia, Egypt, and around the Mediterranean. Results of this analysis will be compared with published analyses of Mediterranean, Egyptian, Nubian, and Near Eastern material in order to quantify any similarities and/or differences. This reveals possible interrelationships between trade, technological understanding, and manufacturing choices made in Egyptian, Nubian and other cultures. This study has shown the extent to which the same primary production centre was providing non-leaded glass to numerous sites around the Mediterranean and down into Nubia. It has also enabled the identification of different types and groups of glass present there, shown the extent and variation of its glass, and has shown that glass was moving to Nubia from India. Recycling has also been identified and isotope analysis has enabled the discovery that the lead used in these Nubian glass objects came from sources in Turkey. While it has been acknowledged that there are gaps in our geographical and chronological knowledge of ancient glass compositions, in particular the early Iron Age to Hellenistic periods in the Mediterranean, the research undertaken in this study has begun to fill some of these gaps by exploring Nubia’s contribution.

description: In many engineering applications, the assessment of reliability has to be done within a limited amount of information, which does not allow to use exact values for the distributional hyperparameters. This is achieved defining probability boxes and assessing the reliability computing the failure probability bounds. Probability boxes are often obtained from known probability distribution functions represented by interval hyper-parameters. In the applications, not only it is of interest estimating the failure probability bounds, but it is also required to identify the extreme realizations leading to the estimated bounds. In this paper, we propose a strategy, based on the Kolmogorov-Smirnov test, to identify the parental distribution function that best fit the distribution of extreme realizations, obtained from the minmax propagation. From the results obtained comparing the strategy with a direct search, it has emerged that the proposed method is generally applicable and efficient.

description: The stress state of a piecewise-homogeneous elastic body, which has a semi-infinite crack along the interface, under in-plane and antiplane loads is considered. One of the crack edges is reinforced by a rigid patch plate on a finite interval adjacent to the crack tip. The crack edges are loaded with specified stresses. The body is stretched at infinity by specified stresses. External forces with a given principal vector and moment act on the patch plate. The problem reduces to a Riemann-Hilbert boundary-value matrix problem with a piecewise-constant coefficient for two complex potentials in the plane case and for one in the antiplane case. The complex potentials are found explicitly using a Gaussian hypergeometric function. The stress state of the body close to the ends of the patch plate, one of which is also simultaneously the crack tip, is investigated. Stress intensity factors near the singular points are determined.

description: What is nowadays called (classic) Clifford analysis consists in the establishment of a function theory for functions belonging to the kernel of the Dirac operator. While such functions can very well describe problems of a particle with internal SU(2)-symmetries, higher order symmetries are beyond this theory. Although many modifications (such as Yang-Mills theory) were suggested over the years they could not address the principal problem, the need of a n-fold factorization of the d’Alembert operator. In this paper we present the basic tools of a fractional function theory in higher dimensions, for the transport operator (alpha = 1/2 ), by means of a fractional correspondence to the Weyl relations via fractional Riemann-Liouville derivatives. A Fischer decomposition, fractional Euler and Gamma operators, monogenic projection, and basic fractional homogeneous powers are constructed.

description: The Training Work Package (WP4) of the PRACE Third Implementation Phase (PRACE-3IP) project was responsible for the face-to-face training of PRACE. It seamlessly continued the training activities of PRACE-2IP starting from September 2013. Between September 2013 and June 2014 the six PRACE Advanced Training Centres delivered 77 courses with 1448 participants with high level of satisfaction of the participants, expressed through a very positive (8.38) overall rating on average for each course. Similarly, the three PRACE seasonal schools of this period, namely the PRACE Autumn School 2013 in Slovenia, the Winter School 2014 in Israel and the Spring School 2014 in Austria, attracted 152 attendees in total and obtained overall ratings of 7.0, 8.4 and 7.1, respectively. Both forms of face-to-face training are complementary, they contribute to the success of PRACE training activities, and should be continued in the future PRACE HPC training.
 In accord with the PRACE-3IP goals most training events address also industrial users, and motivate them by showing the importance and benefits of HPC for the practice.
title: Characterising Bronze Age copper from the Great Orme mine in North Wales to determine and interpret its distribution
Creators: name: Williams, RA

description: The Great Orme copper mine on the coast of North Wales is one of the largest surviving Bronze Age mines in Europe. However, linking the mine to metal artefacts has been impeded by influential claims in the literature of the 1990s that the mine could only produce low impurity metal, which is uncommon in Bronze Age Britain. This has marginalised the importance of the mine as a metal source combined with the claim that the mine was only large because it was worked on a small scale for nearly a millennium. In addition, the past use of lead isotopes has produced confusing evidence due to the mine’s radiogenic ores and a lead ore vein crossing the copper deposit. The main objective of this thesis is to resolve the confusion and contradictions in the literature and allow the distribution of Great Orme metal to be determined and interpreted. Applying an interdisciplinary approach, involving ore geology, mineralogy, geochemistry and pyrotechnology, a new methodology has been developed. This is based on the concept of establishing mine-based metal groups rather than using the existing artefact-based metal groups. Ore samples, taken throughout the Bronze Age mine workings along with metal produced from controlled smelting experiments, have been analysed using a variety of analytical techniques. The full range of the probable chemical composition field and the lead isotope field of Great Orme metal has been established. Confidence in this mine-based metal group has been increased by its consistency with the bronze tool fragments excavated in the mine and with copper prills from the nearby Pentrwyn Bronze Age smelting site. The results have shown that, contrary to the low impurity claims in the literature, the Great Orme mine mainly produced copper with significant nickel-arsenic impurities. Applying the mine-based metal group model to existing data on all Bronze Age metalwork assemblages suggests there was a zenith with large-scale production in the Acton Park assemblage phase (1600/1500-1400 BC), followed by many centuries of very low production. Distribution maps of artefacts that have been newly correlated with Great Orme metal have revealed possible distribution networks across Britain and into mainland Europe. In particular, there are strong links into Brittany but also stretching as far as the Baltic area, possibly related to the amber trade. The implications for mine organisation are reviewed including a potential link to the invention of the palstave, an iconic symbol of the Middle Bronze Age, and possible support or control from the agriculturally richer area of north-east Wales with its strategic position into wider communication networks.
