Résumé :

Increased frequency of extreme weather events has seriously affected forestry operations in south-eastern Europe. A precondition for effective artificial restoration of disturbed forest stands is site-adapted forest reproductive material (FRM). Common garden experiments (provenance trials) may assist in selecting such FRM. The main objective of this study was to establish among-provenance variation pattern using data from a beech provenance trial. Usefulness of the results in selecting seed sources for restoration of European beech stands is discussed. The trial was set up in 2007, at a slope of Medvednica mount facing north-west at 730-750 m above sea level. Plant heights were measured and survival scored in 2008 and 2015. Height increments were calculated and processed to determine variance components due to various effects. Highly significant provenance-by-block interaction was revealed, indicating strong microsite effects on provenance performances. Therefore, corrections were made and provenance mean height increments recalculated. Provenance mean height increment multiplied with survival was used as a measure of a provenance’s adaptedness. Regression tree (RT) analysis was used to determine the pattern of among-provenance variations. A set of provenance clusters was grown using climatic variables related to the provenance stands of origin as criteria. All analyzed effects were significant (provenance: F=2.07, p<0.05; block: F=5.07, p<0.05; provenance by block interaction: F=7.32, p<0.001). Data corrections reduced the interaction effect, thereby increasing reliability of calculated provenance adaptedness indices (AI). Provenances were grouped into 4 clusters due to elevation, mean July temperature and summer heat-to-moisture index (SHM). Cluster 4, containing provenances from the highest altitudes (>750m), had the highest mean AI (143.9±8.4 cm). The lowest mean AI (106.7±14.8 cm) had cluster 1, containing provenances from lower altitudes with lower mean July temperatures (≤18.4°C). Provenances originating from lower elevations with higher mean July temperatures (>18.4°C) were further divided into two clusters due to the SHM variable. Cluster 2 had the second highest mean AI (141.2±1.5 cm) and contained provenances from relatively wetter habitats (SHM≤48.2). Cluster 3, containing provenances from relatively arid habitats (SHM>48.2), had significantly lower mean AI (116.8±8.6 cm). Established among-provenance variation pattern might be used as a tool in selecting seed sources for artificial restoration of beech stands at mount Medvednica. It is advisable to use FRM from higher altitudes and/or from slightly lower altitudes (up to 150 m lower than a restoring site) but featured with warmer and drier conditions compared to the trial. Generally, provenance trials should be utilized as a valuable decision tool in restoring disturbed forest stands but may also be misleading if not well designed and analyzed.

Résumé :

A research was conducted to determine genetic variability and structure of ebony either within provenances or within trees in the same provenance using isozyme analyses. Results of this study are expected to show genetic variability of ebony with different provenances. For the purpose of the study, five provenances of ebony (Maros,Barru, Sidrap, Malili, and Mamuju) were prepared. The isozyme analysis using electrophoresis was applied to determine the genetic variability. The obtained data were statistically analyzed using multivariate and dendrogram analyses with Numerical Taxonomy System (NTSYS) Program applying unwighted pairgroup method and arrithmetic average (UPGMA) approach. Results showed that the variability of genetic provenances of ebony were less than any other tree species. Among the existing provenances, Barru dan Mamuju showed higher genetic variability compared to other provenances. Ebony provenance was generally found to homozygously increase or to performinbreeding. The genetic variability of ebony was mostly derived from the variability in population (95.4%). Grouping individual trees based on their provenances indicated that Malili provenance showed closed relationship to Maros provenance, whilst Mamuju provenance showed closed relationship to Barru and Sidrap provenances.

UDK 582.632.2:581.43/.44(497.6 Kakanj) This paper presents the results of the research of the provenances of beech (Fagus sylvatica L.) in an experiment near Kakanj. Experiments of the provenances were established during the spring of 2007 with 2+0 and 3+0 years-old seedings. The plants were planted in the experimental design of randomized block system in three replications. The results of the survival of plants in 2007, 2008 and 2009, and the root collar diameter of plants and plant height in 2009 are presented in this paper. Studies of the plants’ survival show that the highest percentage of survival rate had the provenance Tešanj – Crni Vrh I, while the lowest percentage of survival rate had provenance Bugojno Vranica - Bistrica. The analysis of the variance showed a statistically significant difference between the provenances, which was confirmed by the Duncan test. Romania provenance Alka - Iulia (10.14 mm) and the Swiss provenance Sihlwald (10.45 mm), had the smallest diameter of the root collar. Provenance from Croatia Dilj Čanglinski (19.43 mm) and provenance Varani kamen (18.46 mm) had the biggest diameter. The greatest average height had a provenance from Croatia Dilj Čanglinski (93.21 cm) and provenance Varani kamen (92.88 cm). The lowest level of height had provenance Alka Romania - Iulia (43.48 cm) and provenance Alesd (52.71 cm).

Résumé :

AbstractFifteen provenances of European beech (Fagus sylvatica L.) were evaluated for stability and adaptability by height growth at four test sites in Bosnia and Herzegovina (1), Croatia (1) and Serbia (2). Provenance trials were established in spring 2007 by planting 2- and 3-yearold seedlings and arranged in a randomized complete block design. The data from seven 6- year-old and eight 5-year-old provenances were obtained in 2009 and analyzed separately. Finlay and Wilkinson’s regression analysis and Additive main effects and multiplicative interaction model (AMMI model) were used to assess provenance by site interaction (P × S) and to identify beech provenances that have high and stable performance in different environments, at the juvenile stage of development. Analysis of variance showed that effects of provenance, site, and P×S interaction are highly significant (p<0.001) in both age groups. Linear regression model evidenced that most of the provenances had regression coefficients not significantly different from unity (b=1.0), except for provenances Sjeverni Dilj Caglinski (HR24) and Vranica-Bistrica (BA59). The partitioning of the total sum of squares (SS) exhibited that the site effect was the predominant source of variation in both age groups of provenances (50.7% and 38.5%, respectively). Additionally, regression analysis explained 15.8% and 33.2% of provenance by site interaction terms, in provenances age six and five years, respectively, while the AMMI analysis accounted for 62.2% and 78.7% in P×S interaction. The results of AMMI showed that the first principal component (PC1) was statistically significant in both age groups. Adaptability and stability of provenances to the test sites were estimated with AMMI1 and AMMI2 biplots. Provenance Sjeverni Dilj Caglinski (HR24) showed constant performance over tested sites, characterizing with aboveaverage height growth at low yielding environments. Provenances HR25 and BA61 showed the opposite type of adaptation, being adapted to high yielding sites. Provenance Valkonya (HU42) was characterized by IPCA1 score close to zero and above average mean height growth, suggesting general adaptation to the tested environments. The implication of P×S was discussed in light of impact of climate change on beech and selection of most suitable provenances for future reforestation programs.

Résumé :

Provenance tests of forest tree species are important experiments in silviculture and tree breeding. Their results provide information about provenances' growth, adaptability, and other features. The research aimed to determine the dynamics of growth and tree shape of common beech plants per provenances in the international provenance test in Bosnia and Herzegovina to choose the best provenances considering wood production and quality. Research was conducted in the provenance test containing eight provenances from Bosnia and Herzegovina, four from Germany, three from Serbia, two each from Croatia, Romania, and Switzerland, and one from Hungary. Provenance test was established in 2007 by planting 2-year-old and 3-year old seedlings. Height and root collar diameter were measured, and tree shape was assessed in 2019. Data were processed in SPSS 26.0. Descriptive statistics, variance analysis, multiple Duncan's test for all traits, and Pearson's coefficient of corelation among morphological traits and tree shape were calculated. Variance for the height and root collar diameter showed statistically significant differences among different ages of plants and among provenances. Provenance from Croatia (Dilj Čaglinski) had the highest, and provenance from Romania (Alba-Iulia) had the lowest average height. The highest average value of root collar diameter had provenance Dilj Čaglinski, and the lowest value had provenance Sihlwald (Switzerland). The highest percentage of category 10 (ideal tree form) had provenance Bad Wildbad (Germany), and categories 1-4 (no silviculture value) had provenance Alba-Iulia (Romania). Pearson's coefficient showed that height, root collar diameter, and tree shape are highly correlated. Considering all the above, when planning forest-breeding works, it is recommended to continue the research and favor provenances with the best growth and tree shape.

Résumé :

The paper presents the results of the research conducted within the European provenance beech trial, in the Teaching Base of the Faculty of Forestry - Debeli Lug. To assess the inter- -provenance genetic variability of beech, using morphological markers, and comparative analysis of the results obtained in two successive years, 10 trees per each selected provenance were sampled. Thirty leaves were collected from each tree (total of 300 leaves per provenance per year). The inter-provenance differences of all morphological leaf characteristics were statistically significant and can be assumed to be the result of the genetic constitution of the provenances themselves. Based on the comparative analysis of the morphological characteristics of beech leaves from 13 different provenances in two research years, it was found that the mean values of most analyzed morphological characteristics were higher in 2017, compared to the results from 2016. Such results could be explained by the different climatic conditions that prevailed in the provenance trial in research years.

Résumé :

UDK 582.475:581.4(497.6 Olovo) The research has been carried out in a formal experiment with silver fir near Očevje-Olovo, with nine provenances originating from natural BiH population of 22 years of age. The research observed following provenances: communities from the area of Bugojno, Bosanski Petrovac, Olovo-Palež, Olovo-Klis, Pale, Konjic, Fojnica, Sokolac, and Prozor. The analysis of diameter on the root collar found that there are statistically significant differences among the provenances. It was also found that the biggest diameter on the root collar was on the provenances of Fojnica, with 75.6 mm, whereas the smallest was on the provenances of Olovo-Klis, with 65.2 mm. In terms of breast height diameter, some statistically significant differences were also found, so that the biggest diameter was on the provenance of Fojnica, with 47.0 mm, whereas the smallest value of this feature was on the provenance of Pale, with 41.6 mm. The analysis of the height of different provenances for the testing period, 1999 – 2005 (7 years), suggested statistically significant differences among the provenances. The biggest value was on the provenance of Bosanski Petrovac, with 407 cm, whereas the smallest height was on the provenance of Olovo-Klis, with 364 cm. The results obtained during this research provide valuable information, which can be used as indicators for successful differentiation of silver fir.

Résumé :

The distribution of pedunculate oak in Bosnia and Herzegovina is important in connecting the southern and eastern provenances of the Balkan Peninsula with provenances from Central Europe. However, due to over-exploitation, pedunculate oak is almost extinct in Bosnia and Herzegovina. This research aims to determine the heredity and production potential of the pedunculate oak from 28 provenances in the Bosnian-Herzegovinian provenance test through the genetic gain of thickness and height growth. The results will be used in selection of best provenances in terms of genetic gain. For this research, height and root collar diameter of pedunculate oak plants in Bosnian-Herzegovinian provenance tests were measured in 2012, 2016 and 2020. The provenance test was established in 2009. It contains 28 provenances from Bosnia and Herzegovina. Heredity and selection differential were assessed using analysis of variance. Possible genetic gain if using five best and one best provenance were determined. The results of the genetic gain for height obtained using data from 2012 and 2020 were low. The results obtained for 2016 indicate that the genetic gain for height, using five best provenances would be 7.62%, and using the best provenance 9.98%. Results of the genetic gain for root collar diameter obtained for 2016 and 2020 were low. For 2012, the genetic improvement using five best provenances would be 4.28%, and using the best provenance 6.32%. The results indicate that by selecting the best provenances of pedunculate oak and their propagation, we can achieve a significant increase in plant height and thickness, i.e., the yield of wood mass. As research concerns juvenile material, it is necessary to continue systematic monitoring, to determine the actual heredity and genetic age, when the trees reach their physiological maturity, and when the annual value oscillations become uniform.

Résumé :

European beech (Fagus sylvatica L.) is one of the most important tree species in Europe. Due to substantial genetic diversity and phenotypic plasticity, beech has successfully adapted to different environments within its natural range. Provenance tests provide a good basis for studying within- and between-provenance genetic variation, due to homogeneous within-trial environmental conditions. The aim of the present study was to determine the within- and between-provenance genetic variability of certain leaf morphological traits among eleven beech provenances, grown in a common garden experiment. Univariate analysis of variance (ANOVA) was used to test for differences among the studied beech provenances. Principal component analysis (PCA) allowed a complex assessment of the relationships among the provenances and an estimation of multivariate relations among the analyzed characters. The results of the study revealed the existence of substantial variability among provenances (p<0.001). Likewise, high genetic variability was observed at the intra-provenance level (p<0.001). The first three principal components (PC1-PC3) explained approximately 81% of the total variance among the European beech provenances tested. The highest contribution on PC1 corresponded to variables related to leaf size: leaf area (-0.882) and leaf width (-0.876). Based on the position of provenances on a PCA scatter plot, it could be assumed that European beech is characterized by a more ecotypic pattern of genetic variation rather than by clinal variation. Also, the presence of considerable genetic diversity within provenances will be important in the light of climate change impact on beech, since it could potentially facilitate rapid adaptation.

Résumé :

L’oggetto di questa tesi è stato lo studio della mineralogia dei sedimenti fluviali ed eolici attuali generati dall’erosione della catena Himalayana, con lo scopo di definire con precisione le segnature composizionali dei diversi domini tettono-stratigrafici dell’orogene. All’approccio basato sulla identificazione e quantificazione delle associazioni di minerali pesanti (densità > 2.90 g/cm3), sono stati affiancate diverse tecniche analitiche complementari, che comprendono la petrografia e la geochimica del sedimento totale, lo studio di dettaglio al microscopio elettronico a scansione e allo spettroscopio Raman delle caratteristiche minerochimiche dei quattro principali gruppi di minerali pesanti che caratterizzano i sedimenti himalayani e orogenici in generale (anfiboli, epidoti, granati, e pirosseni), l’ analisi dei rapporti isotopici di samario e neodimio scolta in collaborazione con Peter Clift presso l’ Istituto Oceanigrafico Woods Hole, oltre all’ analisi geocronologica su zirconi detritici svolta in collaborazione con Pieter Vermeesch presso l’Università di Londra (UCL) affiancata anche da dati analoghi su rutilo, monazite, e titanite ottenuti con la collaborazione di Xiumian Hu e Ronghua Guo presso l’ Università di Nanjing. Le principali aree di studio hanno compreso il Deserto di Thal nel Pakistan centro-settentrionale e gli affluenti del Fiume Indo nel suo corso di montagna dal Ladakh fino al Punjab e gli affluenti principali del Fiume Yarlung (il nome tibetano del Brahmaputra) in Tibet meridionale. Sono stati studiati anche campioni di arenarie Cenozoiche provenienti sia dalle Alpi Occidentali che dal Tibet meridionale. I risultati presentati in questa tesi sono stati pubblicati a primo nome in un volume speciale della rivista internazionale Minerals, sono stati sottomessi nel mese di Settembre e sempre a primo nome a Sedimentary Geology, o sono in preparazione per una prossima sottomissione ad altra prestigiosa rivista internazionale.
Sediments and sedimentary rocks can be considered as geological archives that faithfully reflect their provenance information if the bias introduced by physical and chemical processes during transport and deposition can be properly recognized and corrected for. The sediment provenance analysis both in modern and ancient settings is crucial to trace the sediment sources, reconstruct paleoclimate and paleoenvironment, and interpret the evolution of the Earth’s surface. Modern sediments, unaffected by diagenesis and eroded, tansported and deposited under climatic conditions that are fully known, can provide valuable information on the interactions among the different controlling factors that govern source-to-sink systems. Rivers draining the Himalayan orogen provide the good opportunity to trace the source fingerprinting that is documented in modern fluvial and eolian sand and how these signatures reflect the erosion patterns of the modern and paleo-river systems. A multidisciplinary approach based on petrography, minerology, geochemistry and geochronology is emphasized in this research, in order to obtain a comprehensive provenance information. Our research area focused on the modern sands from two river system: Yarlung River and Indus River. In the Yarlung River system, the Nian River was chosen to investigate the petrographic, mineralogical and chronological signature of sediments from Tethys Himalaya, Greater Himalaya, Kangmar gneiss dome and Transhimalayan ophiolitic suture. Different tectonic domains are characterized by distinct heavy mineral assemblages, e.g., the first-cycle sillimanite and garnet in Greater Himalaya, and clinopyroxene, olivine and enstatite in the forearc ophiolites. Sand carried by the Nian River and its major tributaries, mainly reflects Tethys Himalayan characteristics, consistent with the geochronological results. Erosion rates were also evaluated and circumscribed in the middle Yarlung River catchment. The average erosion rate in the Nianchu catchment is estimated at 0.07-0.10 mm/a, twice as that in the middle Yarlung and Lhasa River catchments, which is principally ascribed to the high erodibility of Tethys Himalayan strata. In the Indus River system, minerochemical analysis of amphibole, garnet, epidote and pyroxene grains, and geochronological analysis of detrital zircons, associated with analysis on petrography, bulk-sediment geochemistry and isotopic geochemistry, in aolian sand from Thal Desert and fluvial sand in selected tributaries draining one specific tectonic domain in the upper Indus catchment, were carried out to discriminate compositional signatures, decipher the provenance information, and trace the erosional evolution of the western Himalaya syntaxis. The compositional fingerprints of Thal Desert sand are characterized by litho-feldspatho-quartzose to quartzo-feldspatho-lithic detrital modes and very rich amphibole-dominated heavy-mineral assemblages. The high heavy mineral concentration, less negative εNd, abundant zircon ages at 40-100 Ma, and specific mineral varietal fingerprints, consistently reflect that the Kohistan arc has acted as the main sediment source. Karakorum appears to contribute less while Himalaya shows higher influence on the Thal Desert sands than modern river sands from the Indus. As a Quaternary repository of wind-reworked Indus River sand at the entry point in the Himalayan foreland basin, Thal Desert sands document higher erosion rates than today in the glaciated areas formed largely by batholites granitoids of the Asian active margin. The close compositional and chronological connection between the Thal Desert and the ancient Indus Delta and Fan deposits, shed new light on the reconstructing of paleodrainage and the understanding of relationship between climatic and tectonic forcing that controlled the erosional evolution of the western Himalayan-Karakorum orogen.

Résumé :

Relying on computing systems that become increasingly complex is difficult: with many factors potentially affecting the result of a computation or its properties, understanding where problems appear and fixing them is a challenging proposition. Typically, the process of finding solutions is driven by trial and error or by experience-based insights. In this dissertation, I examine the idea of using provenance metadata (the set of elements that have contributed to the existence of a piece of data, together with their relationships) instead. I show that considering provenance a primitive of computation enables the exploration of system behaviour, targeting both retrospective analysis (root cause analysis, performance tuning) and hypothetical scenarios (what-if questions). In this context, provenance can be used as part of feedback loops, with a double purpose: building software that is able to adapt for meeting certain quality and performance targets (semi-automated tuning) and enabling human operators to exert high-level runtime control with limited previous knowledge of a system's internal architecture. My contributions towards this goal are threefold: providing low-level mechanisms for meaningful provenance collection considering OS-level resource multiplexing, proving that such provenance data can be used in inferences about application behaviour and generalising this to a set of primitives necessary for fine-grained provenance disclosure in a wider context. To derive such primitives in a bottom-up manner, I first present Resourceful, a framework that enables capturing OS-level measurements in the context of application activities. It is the contextualisation that allows tying the measurements to provenance in a meaningful way, and I look at a number of use-cases in understanding application performance. This also provides a good setup for evaluating the impact and overheads of fine-grained provenance collection. I then show that the collected data enables new ways of understanding performance variation by attributing it to specific components within a system. The resulting set of tools, Soroban, gives developers and operation engineers a principled way of examining the impact of various configuration, OS and virtualization parameters on application behaviour. Finally, I consider how this supports the idea that provenance should be disclosed at application level and discuss why such disclosure is necessary for enabling the use of collected metadata efficiently and at a granularity which is meaningful in relation to application semantics.

Résumé :

The Datalog programming language has recently found increasing traction in research and industry. Driven by its clean declarative semantics, along with its conciseness and ease of use, Datalog has been adopted for a wide range of important applications, such as program analysis, graph problems, and networking. To enable this adoption, modern Datalog engines have implemented advanced language features and high-performance evaluation of Datalog programs. Unfortunately, critical infrastructure and tooling to support Datalog users and developers are still missing. For example, there are only limited tools addressing the crucial debugging problem, where developers can spend up to 30% of their time finding and fixing bugs. This thesis addresses Datalog’s tooling gaps, with the ultimate goal of improving the productivity of Datalog programmers. The first contribution is centered around the critical problem of debugging: we develop a new debugging approach that explains the execution steps taken to produce a faulty output. Crucially, our debugging method can be applied for large-scale applications without substantially sacrificing performance. The second contribution addresses the problem of incremental evaluation, which is necessary when program inputs change slightly, and results need to be recomputed. Incremental evaluation allows this recomputation to happen more efficiently, without discarding the previous results and recomputing from scratch. Finally, the last contribution provides a new incremental debugging approach that identifies the root causes of faulty outputs that occur after an incremental evaluation. Incremental debugging focuses on the relationship between input and output and can provide debugging suggestions to amend the inputs so that faults no longer occur. These techniques, in combination, form a corpus of critical infrastructure and tooling developments for Datalog, allowing developers and users to use Datalog more productively.

Résumé :

Traditionally, an archival fonds is conceptualized as an aggregate of records which are mutually relevant. This mutual relevance is often attributed to the origin of member records in a common context – with this context typically understood as the context of an organization, and more specifically, a department. It is considered difficult to identify mutually relevant records in modern organizations. This difficulty is often attributed to frequent administrative changes which disrupt departmental contexts. This thesis tests a technique that aims to use the information within the records to identify a context common to a set of records. It involves extracting the name of the creator and the name of the modifier from each record, then subjecting this information to a community detection algorithm. It was hypothesized that groups of individuals who frequently modify one another’s records constitute a common context. After applying various community detection algorithms to the records of an organization, the resulting groups of records were presented to the staff of the organization for feedback. Staff clearly indicated that groups of records produced by the community detection algorithms were not mutually relevant. These results can be explained with reference to the works of Jenny Bunn, who argued that an autonomous community only comes into existence when constituent members engage in both “being” and “doing.” During the interviews with staff, it was clear that some algorithms produced groups of people characterized by established relationships (“being”) while others produced groups in pursuit of a joint activity (“doing”). The absence of overlap suggests there were no autonomous subcommunities in this study, and therefore, no common context by which records can be bound. Mutually relevant records can also be formed by employees in their attempts to keep records orderly. To explore this further, it was argued that constructing a folder structure is akin to constructing a narrative, with the narrative components taking the form of records. When numerous employees attempt to organize the same records using different narratives, the aggregate may seem disorderly. This thesis suggests that disentangling these narratives is a method by which order may be restored.

Résumé :

Trace element composition of archaeological artifacts is commonly used for provenance studies. Limestone has generally studied by geologists and there are a few researches done by various archaeological sciences. Although it is a common material for buildings and sculpture it is been thought that limestone used had not imported like marbles. Limestone figurines from Datç
a/Emecik excavations are classified as Cypriote type, which was very popular through 6th century B.C. in the Mediterranean region. Since this type of figurines was found at Emecik numerously to determine its provenance was an important problem. Emecik figurines were examined for their some major, trace elements and REE compositions and results were compared with geological samples which were taken from a near by quarry. Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES), Inductively Coupled Plasma-Mass Spectrometry (ICPMS) have been used for analysis. The methods have been optimized by using standard reference material NIST 1d, NCS DC 73306, and IGS40.

Résumé :

Advances in mass spectrometry in the second half of this century allowed very accurate measurements of isotopic compositions of various elements. In turn it was discovered that due to the radiogenic origin of some of these isotopes their composition often reflects the geochemical history of minerals and rocks. Terrestrial lead is composed of four isotopes, of which three are radiogenic in origin as daughters of uranium and thorium. In geochronology the isotopic composition of minerals helps in dating the ore and rock formations. However, if there is enough diversity amongst the isotopic compositions of different deposits, then their lead isotope composition can be used as a simple and unique 'fingerprint', which can be scientifically measured. This feature can be used as a powerful tool in the identification of sources of ancient metals, because it passes unchanged through the smelting and refining processes. However, one of the most important requirements for such 'lead isotope provenance studies' is empirical investigation of the 'fingerprints' of ore deposits which are relevant to a given archaeological research. In this dissertation the scientific foundations of lead isotope provenance studies are described and examined in detail. All available evidence concerning the possibility of distinguishing isotopically between different European ore deposits is examined and methods of visual and numerical evaluation of the lead isotope data are suggested. Two examples of applications to specific archaeological problems are also given: the identification of sources of metals used for production of Bronze Age Cretan weapons and of non-ferrous metals in the Roman Period in Southern Poland. The interpretation of lead isotope data for archaeological objects is based on nearly 1500 isotopic analyses of ores.

Résumé :

The Service-Oriented Computing (SOC) paradigm, realizing a software design philosophy and architecture - the service-oriented architecture (SOA) - provides the means to develop service-oriented systems by exploiting and composing loosely coupled services. As service-oriented systems become increasingly large-scale and infrastructure-heterogeneous, their execution leads to excessive data production stressing the need for service providers to exhibit accountability about the systems' qualities and actions. Accountability requires that systems faithfully document their execution, being able to answer questions about how the data was produced and processed, referred to as data provenance. Provenance awareness is the functionality providing access to provenance by allowing users to query data about past processes and answer provenance questions. The SOC paradigm promotes composability. For a composite service, the independent audits of atomic services do not simply compose to a connected queryable picture of the provenance across the end-to-end pathways of a composition's execution. Taking into account the inherent complexity of service discovery, selection and dynamic composition aspects of SOC, we realize that we need to carefully design for provenance awareness support by modeling explicitly the provenance data structures and infrastructure independently of specific applications. This thesis proposes a set of formal models, analysis methods, and tools to address this need. We contribute a formal specification and analysis framework for provenance-awareness of service compositions introducing: a faceted classification of provenance questions to formally express provenance requirements acting as analytical metrics for provenance-awareness, a provenance data model capturing the provenance structures of service compositions, a template provenance infrastructure metamodel allowing one to design the provenance infrastructure of atomic and composite services, and a modeling and analysis environment that verifies through simulation and analysis whether the provenance infrastructure system design satisfies a set of provenance requirements. As a proof of concept, we provide a prototype tool implementation of our framework.

Résumé :

Beacon Supergroup rocks of probable Devonian age, containing conglomerate clasts of lithologies unknown in outcrop in southern Victoria Land (SVL) occur in the St Johns Range to Bull Pass Region, SVL, Antarctica. The Lower Taylor Group sedimentary rocks, herein called the Sperm Bluff Formation, unconformably rest on the regionally extensive Kukri Erosion Surface that truncates local basement. The basement complex includes three Plutonic Suites, Dry Valley (DV) 1a, DVIb and DV2 of the Granite Harbour Intrusives that intrude metasedimentary rocks of the Koettlitz Group. Allibone et al. (1993b) suggested a SVL terrane accretion event may have occurred about the same time as accretion of a terrane known as the Bowers terrane in northern Victoria Land (NVL) based on changing chemistry of the CambroOrdovician granitoids. Further, it is suggested that conglomerate clasts of the Sperm Bluff Formation may have been derived from this postulated terrane (Allibone et al., 1993b; and Turnbull et al., 1994). Following extensive fieldwork provenance studies and basin analysis of the sedimentary Sperm Bluff Formation are used here to test these ideas. The Sperm Bluff Conglomerate of Turnbull et al. (1994) is re-interpreted as the Sperm Bluff Formation and described using a lithofacies-based approach. The Sperm Bluff Formation is divided into six lithofacies including 1) Conglomerate Lithofacies; 2) Pebbly Sandstone Lithofacies; 3) Crossbedded Sandstone Lithofacies; 4) Parallelbedded Lithofacies; 5) Low-angle Crossbedded Lithofacies; and 6) Interbedded Siltstone/Sandstone Lithofacies. The intimate field association of the Conglomerate, Pebbly Sandstone and Crossbedded Sandstone Lithofacies ties them to the Conglomerate Lithofacies Association whereas the other three units are independent. The Conglomerate Lithofacies Association is interpreted to represent a wavedominated deltaic environment, based on the presence of broad channels, pervasive crossbedding, paleocurrent and trace fossil data. Both Parallel-bedded and Low-angle Crossbedded Sandstone Lithofacies are interpreted as a foreshore-shore face shallow marine setting on the basis of low-angle crossbeds and trace fossil assemblages. The Interbedded Siltstone and Sandstone Lithofacies is interpreted as an estuarine environment based on alternating siltstone/sandstone beds and the presence of flaser and lenticular bedding, small crossbedded dune sets, mud drapes, syneresis cracks and diverse paleocurrent directions. An estuarine setting is tentatively favoured over a lagoonal setting due to the presence of syneresis cracks small channels and the proximity to a river delta. I suggest that the Sperm Bluff Formation is likely a lateral correlative of the Altar Mt Formation of the Middle Taylor Group, in particular the Odin Arkose Member. This interpretation is based on arkosic nature of the sedimentary rocks, regional paleocurrent patterns, the presence of salmon pink grits at Gargoyle Turrets and trace fossil assemblages. The upper most lithofacies at Mt Suess, the Low-angle Crossbedded Sandstone Lithofacies that only occurs at this site is- suggested as a lateral correlative to the Arena Sandstone, which stratigraphically overlies the Altar Mt Formation, based on quartzose composition, clay matrix, stratigraphic position and trace fossils present. Provenance analysis was carried out on sedimentary rocks and conglomerate clasts using clasts counts of conglomerates, petrographic analysis of clasts, point counts of sandstones and clasts, geochemistry and V-Pb detrital zircon analysis. Conglomerate clasts lithologies include dominantly silicic igneous clasts and finely crystalline quartzite clast amongst other subordinate lithologies such as vein quartz, schist, schorl rock, gneiss and sandstone. Despite past identification of granitoid clasts in the Sperm Bluff Formation (Turnbull et al., 1994), none were found. Rhyolitic clasts of the Sperm Bluff Formation have compositions typical of highly evolved subduction related rocks, although they have undergone post-emplacement silicification. Wysoczanski et al. (2003) date rhyolite and tuff clasts between 497±17 Ma and 492±8 Ma, placing them within error of all three Dry Valley Magmatic Suites and removing the likelihood of correlation to NVL volcanic rocks. Petrographic analysis suggests they are components of a silicic magmatic complex. Chemically the volcanic clasts appear to represent a single magmatic suite (Sperm Bluff Clast Suite), and are clearly related to the Dry Valley Plutonic Suites. Although clasts are not constrained beyond doubt to one Suite, DV2 is the best match. Quartzite clasts of the Sperm Bluff Formation are too pure and old to be derived from a local source. Detrital zircon V-Pb ages for the quartzite suggest zircons were derived from the East Antarctic Craton, and that the quartzite source rocks were deposited prior to the Ross-Delamarian Orogeny. Quartzite with a similar age signature has not been identified; however, the Junction Formation sandstone of northwest Nelson has a similar age spectrum. Sandstones from the Sperm Bluff Formation indicate derivation from a felsic continental block provenance, which contain elements of volcanic, hyperbyssal and plutonic rocks. They are arkosic to quartzose in composition and conspicuously lack plagioclase. Detrital zircon analyses give a strong 500 Ma peak in all 3 samples, characteristic of a Ross-Delamarian Orogen source, with few other peaks. The dominance of a single peak is highly suggestive oflocal derivation. The sedimentary rocks of the Sperm Bluff Formation are interpreted to be derived predominantly from the basement rocks they now overlie. The presence of the regionally extensive Kukri Erosion Surface at the lower contact of the Beacon Supergroup rocks implies an intermediate source must have existed. This most likely contained all components of the formation. I suggest that the DV2 Suite was emplaced in a subsiding, extensional intra-arc setting. Erosion of the uplifted arc region probably occurred from Late Ordovician to Silurian times with deposition of sediments in a subsiding intra-arc basin. Erosion of the rhyolitic complex in this region probably occurred, however, it is likely that some was preserved. Inversion of this basin prior to the Devonian probably provided the means for these sediments to be deposited as the Sperm Bluff Fonnation.

Résumé :

AbstractThe literature of multimedia forensics is mainly dedicated to the analysis of single assets (such as sole image or video files), aiming at individually assessing their authenticity. Different from this, image provenance analysis is devoted to the joint examination of multiple assets, intending to ascertain their history of edits, by evaluating pairwise relationships. Each relationship, thus, expresses the probability of one asset giving rise to the other, through either global or local operations, such as data compression, resizing, color-space modifications, content blurring, and content splicing. The principled combination of these relationships unveils the provenance of the assets, also constituting an important forensic tool for authenticity verification. This chapter introduces the problem of provenance analysis, discussing its importance and delving into the state-of-the-art techniques to solve it.

Résumé :

We address the problem of handling provenance information in ELHr ontologies. We consider a setting recently introduced for ontology-based data access, based on semirings and extending classical data provenance, in which ontology axioms are annotated with provenance tokens. A consequence inherits the provenance of the axioms involved in deriving it, yielding a provenance polynomial as an annotation. We analyse the semantics for the ELHr case and show that the presence of conjunctions poses various difficulties for handling provenance, some of which are mitigated by assuming multiplicative idempotency of the semiring. Under this assumption, we study three problems: ontology completion with provenance, computing the set of relevant axioms for a consequence, and query answering.

Scientific workflows rely on provenance to be understandable, reproducible and trustworthy. Nowadays, there is a growing demand for interoperability between provenance data generated from heterogeneous workflow management systems. To address this issue, some provenance models have been proposed by extending PROV to support specific requirements of scientific workflows. In this paper, we present two prominent provenance models for scientific workflows, PROV-Wf and ProvOne, which are specializations of PROV, and compare their elements and relationships. Our goal is to provide an overview of each one and to support the choice for the most suitable for a specific context.

Résumé :

Managing contextual and provenance information plays a key role in the scientific domain. Activities which are carried out in this domain are often collaborative and distributed. Thus, aiming to examine and audit results already obtained, researchers need to be aware of the actions taken by other members of the group. Contextual and provenance information are essential to enhance the reproducibility and reuse of experiment. The goal of this work is to present a conceptual framework that provides guidelines capable of supporting the modeling of provenance and context in a software ecosystem platform to support scientific experimentation. Preliminary results are also presented when the proposed solution is used to design software ecosystem platform components.

Résumé :

Data provenance consists in bookkeeping meta information during query evaluation, in order to enrich query results with their trust level, likelihood, evaluation cost, and more. The framework of semiring provenance abstracts from the specific kind of meta information that annotates the data. While the definition of semiring provenance is uncontroversial for unions of conjunctive queries, the picture is less clear for Datalog. Indeed, the original definition might include infinite computations, and is not consistent with other proposals for Datalog semantics over annotated data. In this work, we propose and investigate several provenance semantics, based on different approaches for defining classical Datalog semantics. We study the relationship between these semantics, and introduce properties that allow us to analyze and compare them.

Résumé :

Portable X-ray fluorescence (pXRF) technology collects geochemical data at a fraction of the cost of traditional laboratory methods. Although the pXRF spectrometer provides concentrations for 41 elements, only a subset of these elements meet the criteria for definitive, quantitative, and qualitative data. However, high-quality pXRF data obtained by correct application of analytical protocols, can provide robust insight to stratigraphy and sediment characteristics that are often not observed by, for example, visual core logging, grain size analysis, and geophysical logging. We present examples of geochemical results obtained from pXRF analysis of drill core samples from three boreholes located in Canada, that demonstrate: 1) Definitive stratigraphic boundaries observed in geochemical changes obtained from 380 analyses collected over 150 m of core, which intersects three Ordovician sedimentary formations and Precambrian granite. These boundaries could not be reconciled by traditional visual core logging methods. 2) Significant elemental concentration changes observed in 120 samples collected in each of two ~120 m deep boreholes located in a confined paleo-glacial foreland basin. The collected geochemical data provide insight to sediment provenance and stratigraphic relationships that were previously unknown. 3) Abrupt changes in the geochemical signature in a subset of 135 samples collected from a 151 m deep borehole intersecting Quaternary glacial derived till, sands, and ahomogeneous silt and clay succession. These data provide a platform for discussion on ice sheet dynamics, changes in depositional setting, and changes in provenance. Results from each of these studies highlights previously unknown (invisible) geological information revealed through geochemical analyses. A significant benefit of using pXRF technology is refining sampling strategies in near real time and the ability to increase sample density at geochemical boundaries with little increase in analysis time or budget. The data also provide an opportunity to establish a chemostratigraphic framework that complements other stratigraphic correlation techniques, including geophysical methods. Overall, data collected with pXRF technology provide new insights into topics such as spatial correlations, facies changes, provenance changes, and depositional environment changes.

Résumé :

Fort Huachuca Environmental and Natural Resources Division (ENRD) sent funds to ERDC-CERL to develop a historic context that assists Fort Huachuca personnel in identifying the likely history and provenance of numerous historic range features located across Fort Huachuca's training lands. The historic context will be used by cultural resources personnel to evaluate and manage the resources appropriately. Various historic training range features (e.g., structures, fragments, and items left over from previous activities) are located across the ranges of Fort Huachuca, representing its long and storied history. To help identify and catalog these features, ERDC-CERL conducted a field survey of the training ranges in 2016 in or-der to photograph the historic range features. Forty-one historic range features were identified. Researchers conducted archival research, literature reviews, and image analysis of historic and current maps and photographs to identify the 41 historic range features and place them within a chronological context of Fort Huachuca's training ranges. The report concludes with guidance on how to identify and associate sites and features within the overall historic training range chronology and evaluate them appropriately for significance and National Register of Historic Places (NRHP) eligibility.

Résumé :

L’objectif principal de ce rapport est de présenter une analyse descriptive de la mobilité sociale des diplômés du baccalauréat des différentes universités du Québec selon le domaine d’études, mobilité étant ici captée par la transmission intergénérationnelle du revenu. À partir de données administratives sur l’ensemble des étudiants du Québec, il est possible d’observer les taux de diplomation ainsi que les revenus des diplômés une fois sur le marché du travail, le tout par quintile de revenu parental. Au niveau de la fréquentation universitaire de premier cycle au Québec, nous observons une surreprésentation des étudiants provenant de milieux plus aisés. Nos résultats suggèrent également que le taux de diplomation des étudiants au baccalauréat est plus faible pour les étudiants provenant de familles à faible revenu et augmente avec le quintile de revenu parental. Notre analyse de la mobilité intergénérationnelle, à l’aide d’une matrice de transition, suggère que les jeunes diplômés universitaires ont une assez bonne mobilité relativement à la population comprenant tous les niveaux de scolarité, et que les étudiants provenant de milieux moins favorisés ont une mobilité nettement supérieure à leur population de référence. Nous calculons aussi, par université et domaine d’études, une mesure de mobilité intergénérationnelle qui tient compte de l’accès aux études universitaires et de la mobilité ascendante (passer du quintile inférieur de revenu au quintile supérieur). On constate que la mobilité ascendante varie d’une université à l’autre, mais également par domaine d’études, les institutions spécialisées en ingénierie et les programmes en science, technologie, ingénierie et mathématiques démontrant les mobilités ascendantes les plus élevées. Une limite importante de nos données est que l’horizon de temps suivant l’obtention du diplôme est limité, de telle sorte que les revenus d’emploi observés ne sont pas nécessairement représentatifs du revenu permanent des diplômés.
