Повний текст джерелаThe goal of this thesis is to provide enhanced mechanisms to deploy competitive services in a rapid and cost-effective manner. To achieve this goal, we first propose an automatic service composition model relying on an IMS/Web converged environment. This service composition model is intended to be one in which even non-professional users can easily reuse existing services to create new services. To further improve the automatic service composition feature, three strategies including passive update, active update and hybrid update are proposed and analyzed. We then propose a centralized service exposure framework for a variey of services, including Telecom / Web / Device / user-generated services. This framework aims at enhancing the user-centric and convergence features, and providing the unified access to diverse services.Subsequently, two P2P based service information sharing models are designed to complement the centralized service exposure model : i) A hierarchical P2P based model, which reuses Chord for guaranteeing the service discovery efficiency, meanwhile adopts the concept of abstract service publication and discovery for enabling the ambiguous services searching. ii) A triplex P2P overlay based model, which mainly targets the devices offered services. In this model, we use the gateways to delegate the devices residing in them for the global service exposure, and use a triplex overlay based architecture, which includes an underlying unstructured P2P layer, a Semantic Overlay Network (SON) based overlay and a service dependency overlay, for the service information sharing and discovery

Повний текст джерелаThe aim of this thesis has been to develop and validate the user interface of a service composition tool for creating mobile tourist services in a city environment. The project has been conducted in cooperation with SINTEF and the Norwegian research project UbiCompForAll. As part of this thesis, a number of scenarios were created initially, showing what kind of functionalities accessed using mobile devices might be useful for tourists in the city. Based on these scenarios, the graphical user interface of a composition service tool was created and then assessed through the involvement of several users using a paper prototyping approach. The results from the paper prototyping assessment showed that the proposed interface is generally easy to understand and use, although there were a number of improvements necessary in the areas of information abstraction, module naming and letting users be able to see the final product of the composition. In addition, as part of the assessment of the proposed interface, the realizability of the services specified using this interface was evaluated. An architecture for the service derived from the specification developed by the user was defined. This enabled us to check that all the information necessary for creating the composed services can be provided when using the proposed user interface.

I have designed and implemented a software environment, a Windows application called Hyperscore, that presents a novel, easy-to-learn interface for composing richly textured music through line gestures. The program allows the user to command a set of music-manipulation algorithms written by Mary Farbood [Farbood, 2001]. The interface is both compelling and interesting for musically untrained users, and rich enough that such users, after sufficient practice, can create music that professional musicians find to be of high quality. While many musical composition programs geared for musically untrained users exist, it is its unique user interface, its use of freely drawn line-gestures, zooming navigation, and simple symbolic icons, that helps make this program unique. The program was designed to enable musically untrained children, ages ten or older, to compose three-minute pieces for a string orchestra, given only a week or so of two-hour daily workshops. The program succeeded in this, and has been presented to audiences in Berlin, Dublin, and Glasgow as a part of Toy Symphony. The program has also been made available for download.

Повний текст джерелаMesmo depois de 80 anos de pesquisas intensas, a composição das estrelas de nêutrons permanece desconhecida, uma vez que tanto a matéria densa do interior desses objetos compactos quanto a matéria se movendo em torno deles encontram-se em condições físicas extremas, irreprodutíveis em laboratórios terrestres. Nessa Tese, seguimos quatro diferentes caminhos interconectados para abordar esses objetos extremos. Primeiramente, exploramos a estrutura matemática das estrelas de nêutrons, construindo soluções parametrizadas unicamente pela densidade central, apropriadas para estudar o comportamento estrutural dessas estrelas em diversas situações. Em seguida, adotamos uma abordagem nova, a teoria da informação, para inferir uma hierarquia de equações de estado, mostrando que as estrelas de quarks seriam, por sua conformação, favorecidas na Natureza. Estudando a emissão em raios-X advinda do sistema binário de baixa massa 4U 1608--52, que contém uma estrela de nêutrons, limitamos o tamanho físico da fonte emissora, mostrando que não deve estar longe da superfície da estrela compacta. Para isso, empregamos uma técnica inédita no cálculo dos \"time lags\". Por fim, mostramos que é possível obter restrições à massa do quark estranho e ao \"gap\" de energia da CFL diretamente das observações. Concluímos essa Tese com a afirmação de que a matéria estranha é, estrutural e energeticamente, favorecida pela Natureza, muito embora exista uma barreira entrópica a ser superada e uma densidade central mínima a ser atingida logo após o colapso da estrela progenitora. Se essa barreira foi superada na Natureza, apenas observações futuras mais refinadas dirão.

Повний текст джерелаThis thesis is concerned with the composition of the urban rhythms generated by urban design and planning. It recognises the temporal limitations of the graphic urban masterplan, with its tendency of being static and singular in the composition of urban expérience. Thus it proposes the integration of rhythm into the urban design and planning process, with the aim to improve the temporal quality of urban design. In order to represent these urban rhythms, as designed in the graphic masterplan, we propose their sonification. A Sonified Urban Masterplan (SUM) tool was developed, allowing the sonification of multiple layers of maps along a number of paths of interest. An urban sonic code was then developed in order to map the relevant graphic urban parameters into sound parameters. This sonification strategy was applied to the city of Paris as a case study, producing a sonified set of maps whose composition could be ‘listened’ to over time. Temporal issues concerning human movement, transport infrastructure, activity distribution, and the structuring of urban form and design elements could be represented and heard. We then investigated the potential of the SUM tool as a design and planning tool. Thus through the integration of sonification in urban design and planning, this thesis permits the spatio-temporal representation and composition of urban form

Повний текст джерелаHigh elevation, mountainous regions have a high concentration of mining activities and resulting acid mine drainage (AMD) that is typically acidic and often contains elevated concentrations of metals. The impacts of AMD on denitrifying microbial communities is not well understood, despite these organisms’ central role in the nitrogen cycle, contribution to greenhouse gas production, and potential to provide ecosystem services through the mitigation of nitrogen pollution. This study examined denitrifying microbes across four regions within the Iron Springs Mining District (13 sites over four time-points) located in Southwest Colorado at high elevation that receive AMD or naturally-occurring acid rock drainage (ARD). Denitrification functional gene sequences ( nirS and nirK coding for nitrite reductase) had a high number of observed OTUs (260 for nirS and 253 for nirK) and were observed at sites with pH as low as 3.2, dissolved oxygen as low as 1.0 mg/L, and metals >10 mg/L (including aluminum, iron, manganese, and zinc). A majority of the nirK and nirS OTUs (> 60%) were present in only one sampling region. Approximately 8% of the nirK and nirS OTUs had a more cosmopolitan distribution with presence in three or more regions. Phylogenetically related OTUs were found across sites with very different chemistry. The total nirS community structure was correlated to iron, conductivity, sodium, and calcium, which may suggest that these factors play an important role in shaping the nirS community. Overall, these findings improve upon our understanding of the potential for denitrification within an ecosystem impacted by AMD and provide a foundation for future research to understand the rates and physiology of these denitrifying organisms.

Повний текст джерелаThe present thesis aims at characterizing the electronic properties of solution-processed hybrid organic-inorganic perovskites (HOIPs) in general, and the HOIP methyl ammonium (MA) lead iodide-chloride (MAPbI3-xClx) films, in particular, at different stages, namely from its formation to its degradation, by means of photoelectron spectroscopy (PES). Firstly, the formation of MAPbI3-xClx films upon thermal annealing is monitored by a combination of PES, time-of-flight secondary ion mass spectrometry, and grazing incidence X-ray diffraction for disclosing changes in electronic properties, film composition, and crystal structure, respectively. Overall, the results point to the essential mediating role of chlorine in the formation of a highly textured perovskite film. The film formation is accompanied by a change of composition which leads to the film becoming more n-type. The accumulation of chlorine at the interface between perovskite and the underlying substrate is also unambiguously revealed. Secondly, the separate effects of water and oxygen on the electronic properties of MAPbI3-xClx film surfaces are investigated by PES. Already low water exposure – as encountered in high vacuum or inert conditions – appears to reversibly impact the work function of the film surfaces. Water vapor in the mbar range induces a shift of the valence band maximum (VBM) away from the Fermi level accompanied by a decrease of the work function. In contrast, oxygen leads to a VBM shift towards the Fermi level and a concomitant increase of the work function. The effect of oxygen is found to predominate in ambient air with an associated shift of the energy levels by up to 0.6 eV. Overall, the findings contribute to an improved understanding of the structure-property relationships of HOIPs and emphasize the impact of least variation in the environmental conditions on the reproducibility of the electronic properties of perovskite materials.

Повний текст джерелаIn hot dense plasmas, the free-electron and ion spatial distribution may strongly affect the atomic structure. To account for such effects we have implemented a potential correction based on the uniform electron gas model and on a Thomas-Fermi Approach in the Flexible Atomic Code (FAC). This code has been applied to obtain energies, wave-functions and radiative rates modified by the plasma environment. In hydrogen-like ions, these numerical results have been successfully compared to an analytical calculation based on first-order perturbation theory. In the case of multi-electron ions, we observe level crossings in agreement with another recent model calculation. Various methods for the collision cross-section calculations are reviewed. The influence of plasma environment on these cross-sections is analyzed in detail. Some analytical expressions are proposed for hydrogen-like ions in the limit where Born or Lotz approximations apply and are compared to the numerical results from the FAC code. Finally, from this work, we study the influence of the plasma environment on our collisional-radiative model so-called -Foch-. Because of this environment, the mean charge state of the ions increases. The line shift is observed on the bound-bound emission spectra. A good agreement is found between our work and experimental data on a Titanium plasma

Повний текст джерелаNeste trabalho desenvolvem-se generalizações das funções de Shannon e de Simpson e estudam-se as suas propriedades, nomeadamente de caracterização de valores extremos. Aquelas funções, definidas desde o final dos anos quarenta, têm sido utilizadas em ecologia quantitativa como medidas (ou índices) de diversidade, equitabilidade e de dominância. Apresentam uma única solução crítica designada por solução equitativa, que é interpretável como um ponto de equilíbrio de um sistema dinâmico. Nos anos oitenta, aquelas funções foram introduzidas na Ecologia da Paisagem como medidas (ou índices) de avaliação da diversidade de mosaicos de paisagem. Essas medidas só introduzem informação de ordem corológica - proporções de ocupação do solo por k diferentes habitats - e ignoram qualquer caracterização de ordem topológica das componentes do mosaico, por exemplo relativa à biodiversidade característica dos diferentes elementos do mosaico de paisagem. Os desenvolvimentos que agora se apresentam visam contribuir para o preenchimento dessa lacuna. Nas generalizações estudadas o lugar das soluções de equilíbrio passa a depender da valorização atribuída a cada componente e, como consequência, a solução equitativa passa a ser apenas uma solução, dentro da variedade dos equilíbrios da generalização efectuada. As funções aqui apresentadas, que designamos por índices de diversidade sistémica e índices de valor sistémico do mosaico de paisagem permitem aprofundar o estudo das soluções de composição de um mosaico por k componentes, distintas e espacialmente intersubstituíveis. Daí a designação conjunta de índices para o diagnóstico de proporções do ecomosaico. Os resultados teóricos estabelecidos permitem controlo conceptual e analítico sobre as relações envolvidas na caracterização quantitativa das componentes do mosaico e do seu efeito no valor do índice. Ilustra-se computacionalmente o estudo feito, com um conjunto de simulações envolvendo 4 variáveis. Os índices são utilizados num exemplo relativo ao diagnóstico do mosaico de paisagem no Norte do concelho de Nisa colocado a propósito da expansão do eucaliptal (Eucalyptus globulus) no período 1970-1990. S5o apresentadas outras perspectivas com que estas funções podem vir a ser utilizadas noutros campos da Ecologia, em particular permitindo revisitar o paradigma diversidade-estabilidade---------------------------------------ABSTRACT - In this work we build generalizations of Shannon and Simpson's functions with emphasis on the study of extreme values and the characterization of extreme points. Shannon and Simpson's functions were defined in the late forties and have been used in quantitative ecology as measures (or indices) of diversity, evenness and dominance. They present a single critical solution, the equitable solution, which may be interpreted as the equilibrium point of a dynamic system. About the beginning of the eighties, those functions were introduced in Landscape Ecology, as measures (or indices) of diversity in landscape mosaics. Those measures just deal with information at the chorological level of landscape - the proportions of area of k different habitats - and ignore any characterization of the topological level of the elements of the mosaic, such as the biodiversity of the different ecosystems. This work makes a contribution toward solving that omission. In the generalizations we have studied the equilibrium points depend on the values attached to each element, and, as a consequence, the equitable solution is just a solution in the equilibrium manifold of the respective generalization. We name the new functions as systemic diversity indices and systemic value indices of the landscape mosaic, and they allow for the study of the relative composition of a mosaic with k distinct components, spatially interchangeable. We name globally those indices as indices for the diagnosis of proportions of composition of the ecomosaic. The theoretical results allow for conceptual and analytical control over the quantitative relationships involved in the value of the indices. We present simulations of the behavior of the new functions reaching a total of 4 variables in presence. The indices are used in an example relative to the diagnosis of a landscape mosaic at the North of Alentejo (Nisa), motivated by the expansion of Eucalyptus globulus in the region, in the period 1970-1990. We refer to other fields of Ecology where these functions could be used, in particular allowing revisiting the paradigm diversity-stability.

Повний текст джерелаTheoretical investigations of spectroscopic and magnetic properties of metallic systems in the bulk, as well as in nanostructured materials, have been performed within the density functional theory. The major part of the present work studies the differences between binding energies of electrons tightly bound to the atoms, the so-called core electrons (in contrast with the valence electrons), that is, core-level binding energy shift (CLS).
By comparison between corresponding elemental core-levels for atoms situated in different chemical environments we obtain fundamental understanding of bonding properties of materials. The method of choice was the complete screening picture, which includes initial and final state effects on the same footing. The usefulness of CLS stems from that it is sensitive to differences in the chemical environment of an atom, which can be affected on one hand by the global composition of e.g. disordered materials, surfaces and interfaces, and on the other hand by the very local environment around an atom. Here CLSs have been obtained for both components in the fcc random alloys AgPd, CuPd, CuNi, CuPt, CuAu, PdAu, NiPd and NiPt. Moreover the model was extended to the Auger kinetic energy shift for the LMM Auger transition in AgPd alloys. Studies were also applied to the near surface and interface regions of PdMn nano structures on Pd(100), thin CuPd and AgPd films on inert Ru(0001), and at interfaces. The disorder broadening on CLS due to local environment effects was calculated in selected alloys.
A part of the thesis concern investigations related to the magnetic ordering in Invar alloys, including the influence of local environment effects. A study was made for the dependence of effective exchange parameter on the electron concentration, volume and local chemical composition.

"On the Chemical Composition of Metal-Poor Stars : Impact of Stellar Granulation and Departures from Local Thermodynamic Equilibrium on the Formation of Spectral Lines." Doctoral thesis, Uppsala University, Department of Astronomy and Space Physics, 2006. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-7121.
Повний текст джерелаThe information about the chemical compositions of stars is encoded in their spectra. Accurate determinations of these compositions are crucial for our understanding of stellar nucleosynthesis and Galactic chemical evolution. The determination of elemental abundances in stars requires models for the stellar atmospheres and the processes of line formation. Nearly all spectroscopic analyses of late-type stars carried out today are based on one-dimensional (1D), hydrostatic model atmospheres and on the assumption of local thermodynamic equilibrium (LTE). This approach can lead to large systematic errors in the predicted stellar atmospheric structures and line-strengths, and, hence, in the derived stellar abundances. In this thesis, examples of departures from LTE and from hydrostatic equilibrium are explored. The effects of background line opacities (line-blocking) due to atomic lines on the statistical equilibrium of Fe are investigated in late-type stars. Accounting for this line opacity is important at solar metallicity, where line-blocking significantly reduces the rates of radiatively induced ionizations of Fe. On the contrary, the effects of line-blocking in metal-poor stars are insignificant. In metal-poor stars, the dominant uncertainty in the statistical equilibrium of Fe is the treatment of inelastic H+Fe collisions. Substantial departures of Fe abundances from LTE are found at low metallicities: about 0.3 dex with efficient H+Fe collisions and about 0.5 dex without. The impact of three-dimensional (3D) hydrodynamical model atmospheres on line formation in red giant stars is also investigated. Inhomogeneities and correlated velocity fields in 3D models and differences between the mean 3D stratifications and corresponding 1D model atmospheres can significantly affect the predicted line strengths and derived abundances, in particular at very low metallicities. In LTE, the differences between 3D and 1D abundances of C, N, and O derived from CH, NH, and OH weak low-excitation lines are in the range -0.5 dex to -1.0 dex at [Fe/H]=-3. Large negative corrections (about -0.8 dex) are also found in LTE for weak low-excitation neutral Fe lines. We also investigate the impact of 3D hydrodynamical model stellar atmospheres on the determination of elemental abundances in the carbon-rich, hyper iron-poor stars HE 0107-5240 and HE 1327-2326. The lower temperatures of the line-forming regions of the 3D models compared with 1D models cause changes in the predicted spectral line strengths. In particular we find the 3D abundances of C, N, and O to be lower by about -0.8 dex (or more) than estimated from a 1D analysis. The 3D abundance of Fe is decreased but only by -0.2 dex. Departures from LTE for Fe might actually be very large for these stars and dominate over the effects due to granulation.

Повний текст джерелаThis study provides an approach to the comprehension of the mesoscale structure in the habitat patterns of three major tropical tunas species, yellowfin (Thunnus albacares; YFT), skipjack (Katsuwonus pelamis; SKJ) and bigeye (Thunnus obesus: BET). These species, mainly caught by the purse seiner's fishery worldwide, represent 20% and 13% of the world total production for the Indian and the Eastern Pacific oceans respectively. Single set records from this fishing gear in both, the Indian and in the Eastern Pacific oceans, were used to separately evaluate the environmental characteristics of their fishing grounds for three fishing modes: free school (FS), log (LOG) and fish aggregated devices (FADs) and several individual sizes. Prior to the analyses, a statistical expert-based method was applied to detect and classify thermal fronts at basin scale whereas the anticyclonic and cyclonic eddies are detected, based on the winding angle method. The distances of the catch positions from these structures were then calculated. We found that strong fronts are mostly found in coastal regions and weak fronts in the open ocean. This allows the consideration of the frontal intensity helps to spatially differentiate mechanisms of frontogenesis than may attract tunas. In addition to these mesoscale components, classic, temporal and fishery-related variables were added to describe the fishing environment. We used the Boosted Regression Tree (BRT) method to create a three step modeling scheme for each study area in order to explore the responses of the catch level and size for the different fishing modes, also considering the effect of randomly distributed catch positions, in order to separately estimate the mesoscale effects. The relative dominance of each species is also explored and globally shows similar results than for the catch level. All BRT models show that the catch level was better explained by the environment for free school (FS) than for FADs fishing modes and that the differences in distribution were more important among fish-sizes than among species. We quantify for the first time the strong influence of the mesoscale in determining tuna's habitat, confirmed by the poor explanation obtained in all random models, mainly for the IO. For both oceans, small individual were strongly related with the proximity to mesoscale eddies (<200 km) whereas the larger individuals area found at larger distances. A low influence of mesoscale fronts was found mainly for the Indian ocean whereas the opposite pattern was observed for the EPO, except in the coastal regions where strong fronts become important. Different environmental conditions were observed in well defined sub-regions as the coastal upwelling, the equatorial tongue, and the Costa Rica Dome. Contrarily to the Indian ocean were the fishing grounds are relatively homogeneous in term of Sea Surface Temperature and chlorophyll concentration, these two parameters highly influence the tuna distribution in the EPO. In the Indian Ocean, the total percentages of relative contribution by category of variables for all models were 34% for the mesoscale, 39% for the classical variables and 27% for others (temporal and fisheries related). For the Eastern Pacific, even if mesoscale remains important (37%), the most relevant ones were the classical variables with 55% of the total relative contribution (8% for others).

Повний текст джерелаSaproxylic species living in old hollow trees have low dispersal rate. Many of the species are threatened since their micro habitats are rare. To prevent some of these species from going extinct their habitats have to have the right management. In some areas artificial environment could be a solution. The aim of this study was to investigate if the insects that are dependent on tree cavities with wood mould would colonize an artificially created habitat: large wooden boxes filled with artificial wood mould placed on tree trunks. The boxes were filled with substrates like oak saw dust, oak leaves, dead hens, hen excrements, medicago (Medicago falcata flour) or potatoes. Over three years, 136 species and 10 380 specimens were caught in 47 boxes. The groups classified as specialists were in general statistically significant more often than groups classified as generalists. Dead hen was the substrate with the highest number of species, although differences were small. In conclusion, a large number of species, including red listed ones and saproxylic specialists used the boxes. A dead hen in the box gave some extra species and 1800 meters was too long for some of the species to disperse. Hence, the prospects for using artificial environments are good especially to reduce habitat availability gaps in time and space.
