Повний текст джерелаThe short review of the Open Geospatial Consortium (OGC) web services have been given in this work from the perspective of server and client applications. The problems of the exchange of spatial data in the complex systems as municipal service have been analysed. Based on analysis of data exchange, the model has been proposed to improve communication and progress of the whole system by implementing OGC web services. Described model of spatial data distribution can be applied to all complex systems, but also within smaller systems such as companies which consist of more sectors or subsystems.

Повний текст джерелаMode-stirred reverberation chambers (RC) are used in the industry to test the immunity or the susceptibility of on-board electronic systems (plane, automobile, smartphone) towards the electromagnetic waves present in their environment. Mode-stirred RCs have to comply with a number of statistical criteria fixed by international standards. The chief criterion relies on a statistically uniform and isotropic field around the object under test. In order to improve and master the statistical properties of these systems for frequencies close to their lowest useable frequency, we suggest making them chaotic to take advantage of universal statistical properties of the resonances of chaotic cavities. We first show how to make chaotic RCs by simple modifications of a conventional RC and how to extend the predictions of the random matrix theory applied to the effective hamiltonien describing the open chaotic systems, to the case of vectorial fields. Then, we compare, by means of simulations and experiments, the distributions of intensity and the fluctuations of the maxima of the field in a conventional RC and in a chaotic RC close to the lowest useable frequency. This work illustrates that the universal spectral and spatial statistical properties of chaotic RCs allow to better comply with the criteria required by the international standards

Повний текст джерелаThe Air Force SEEK EAGLE Office (AFSEO) was chartered by the Secretary of the Air Force in December 1987. The mission of the AFSEO is to provide the United States Air Force increased combat capability through central management of the aircraft-stores certification process and provide in-house engineering and operations research capabilities. Additionally, the AFSEO is required to ensure the future viability of the aircraft-stores organic in-house capability with the insertion of evolving technologies. To accomplish this mission, the AFSEO employs all phases of the test process; from Digital Model and Simulation (DMS) to Open Air Range (OAR) flight tests. The AFSEO desires to prepare for the future DoD environment, and minimize the cost of developing its products that require advanced sensors and telemetry capability. For a number of years, a mainstay in the process has been instrumented aircraft. These aircraft were specially instrumented to support the mission of AFSEO. Similarly, stores were instrumented to obtain environmental data such as loads and vibration. With the rising cost of instrumentation and the national DoD trend to reduce the cost of development and maintenance of instrumentation, a new method will need to be found. Several advanced concepts in ground and airborne instrumentation at Eglin AFB are needed to support the mission of the AFSEO. These include a new generation of telemetry devices, sensors, and data acquisition components to provide rapid and cost effective instrumentation of test aircraft, stores, and suspension equipment. The new generation telemetry will provide integrated circuitry with “peel and stick” subminiature telemetry sensors. These telemetry sensors will provide flutter and structural loads data for aircraft-stores combinations. In conjunction with the telemetry sensors, advanced aircraft platform instrumentation will be needed to match precision flight mechanics to the spatial telemetry measurements for stress, strain, and dynamic activity of stores.

Повний текст джерелаA informação geográfica está cada vez mais presente em diversas áreas de conhecimento, sendo que cerca de 80 % das bases das bases de dados inclui informação espacial. Processos de visualização de informação geográfica e aplicação de algoritmos com componente geográfica são já comuns no dia-a-dia de qualquer utilizador da internet. O acentuado desenvolvimento das tecnologias de informação e comunicação tem resultado no aparecimento de tecnologias cada vez mais eficientes, e com capacidade de lidar com grandes volumes de dados com componente geoespacial. Apesar dos esforços dos últimos anos no desenvolvimento das tecnologias de código aberto e licença livre (open source) relacionados com esta área, são ainda escassas as opções que não impliquem instalação de software e que sejam acessíveis a diversos públicos. Os Censos em Portugal representam a maior fonte de informação sobre população, família e habitação disponível, tendo esta um carácter espacial muito definido e compreendendo informação com potencial interesse para diversos tema de investigação. Assim, o que se propõem neste projecto é a criação de um protótipo de plataforma na web que permita ao utilizador fazer análise espacial sobre os seus dados e/ou um conjunto de dados dos censos disponibilizado pela plataforma. Os métodos incluem visualização, análise de autocorrelação espacial e criação de modelos de regressão espacial com base nos dados mencionados. Além da evidente funcionalidade a atingir, pretende-se ainda fazer um levantamento das tecnologias (software e ferramentas) Open Source disponíveis para a construção de um Web Sig (desde a base de dados, ao sevidor de dados espaciais e disponibilização e análise dos mesmos), bem como das suas potencialidades e limitações actualmente. Finalmente, pretende-se fazer uma integração de três elementos: uma compreensão dos métodos estatísticos de análise espacial referidos, uma exploração das tecnologias (ao nível de software) Open Source disponíveis para os fins definidos e a definição de estruturas de arquitectura de acordo com a finalidade proposta.
Geographic information is increasingly more present in several areas of knowledge, resulting in the fact that around 80% (Zhang et al., 2010) of the databases include spatial information. Processes of visualization and application of algorithms to spatial data are already common in the daily routine of any internet user. The accentuated development of information and communication technologies have resulted in the appearance of increasingly more efficient technologies with the capacity of dealing with big data volumes with a geospatial component. Despite the effort over the last years in the development of Open source technologies related with this area, options that do not require the installation of software and that are accessible to a diverse range of publics are still lacking. In Portugal, Census represent the biggest source of information about population, family, housing available having a defined spatial character and comprehending information with potential interest in a wide range of investigation themes. As a result of the above, what is proposed in this project is the creation of a platform on the internet that allows the users to perform spatial analysis over their and/or a default data set from Census made available by the platform. The methods to be applied include visualization, spatial autocorrelation analysis and building spatial regression models over a defined dataset. Besides the evident functionality to achieve it is also pretended to gather an overview over the open source technologies available for the construction of a Web Gis (from the database to the geospatial data server and the display and analysis of the mentioned data) as well as their potentialities and limitations at the moment. Finally it is aimed to integrate three elements: an understanding of spatial analysis methods to be applied to geospatial data in areal sections, an exploration of the technologies available for the proposed goals mainly within the Open Source software area and the definition of system architectures according to the proposed objectives.

Повний текст джерелаIn this paper we investigate the use of general topological spaces in connection with a generalised variant of membrane systems. We provide an approach which produces a fine grain description of local operations occurring simultaneously in sets of compartments of the system by restricting the interactions between objects. This restriction is given by open sets of a topology and multisets of objects associated with them, which dynamically change during the functioning of the system and which together define a notion of vicinity for the objects taking part in the interactions.

Повний текст джерелаThis thesis looks at aspects relating to vegetated open space in the quaternary catchment of the Lourens River, Cape Town, South Africa in 2005 and at GoogleEarth as a source of imagery for research. The research questions were: “Is GoogleEarth a suitable source of imagery for spatial analysis of landscapes?”; “What was the potential access (proximity) to vegetated open space of at least 900 m2 in the Lourens River quaternary catchment in 2005?”; “How many vegetated open spaces with an area of at least 900 m2 were present in the Lourens River quaternary catchment in 2005?” and “What spaces within the urban edge in the Lourens River quaternary catchment can be said to have some protection from development?” Open space has multiple benefits for humans in terms of health and social interaction.In urban areas, it is also important for biodiversity conservation. In Cape Town, this is critical since the city has critically endangered national vegetation types that only occur within its boundaries and 319 IUCN Red List species within its boundaries.Proximity does not reflect use of open space which is affected by the size of the open space, quality of the open space, neighbourhood attributes and individual and collective perceptions of the open space. Quality of vegetated open space is dependent on its facilities and maintenance which are largely determined by its management. In Cape Town, open space management is mainly mowing/brush cutting all spaces which has a negative impact on biodiversity retention. Mowing is continued because of popular demand so action needs to be taken to change popular perceptions.Google Earth is readily available and widely used. It is used for research in diverse disciplines. Local Internet connection problems complicated this study. Alignment and projection problems were encountered in this study. Thus Google Earth geospatial issues make it a poor choice of imagery source for large scale spatial analysis of landscapes.Open space was digitized in Google Earth and transferred to a propriety GIS for editing. Vegetated spaces with a minimum of 900 m2 and a width of at least 15 m were selected from the approximately 1025 digitised spaces. Google Earth imagery was used because it is readily available. Euclidean distances of 300 m, 500 m, 800 m and 900 m (taken from literature) were used to buffer the digitized vegetated open spaces and other data on schools, train stations, bus routes and taxi routes in and within 900 m of the catchment. Buffer analysis was carried out. Data from the City of Cape Town and a schools layer were used to determine the number of cemeteries,community parks, nature reserves and school grounds – space regarded as having some protection from development - within the urban edge of the city and what area they covered.Within or partially within the Lourens River quaternary catchment, 593 vegetated open spaces of at least 900 m2 were identified. The analysis showed that only two houses were beyond 300 m from a vegetated open space. There was vegetated open space within 300 m of all the schools, stations, bus and taxi routes within the catchment and in close proximity to the catchment. Within the urban edge, only 124 spaces were found to be protected, of which only one was a nature reserve.Most of the open spaces are not formally designated as open space and are vulnerable to development. Much development has taken place since 2005 in the Lourens River quaternary catchment so action is needed to ensure proximity to vegetated open space remains a positive feature of the area.Expanding the present research to cover a larger area would provide additional baseline data. Further research could consider the loss of open space over time and the impact of management on the quality of designated open space.

Повний текст джерелаHealth is an indispensable attribute of human life. In modern age, utilizing technologies for health is one of the emergent concepts in several applied fields. Computer science, (geographic) information systems are some of the interdisciplinary fields which motivates this thesis. Inspiring idea of the study is originated from a rhetorical disease DbHd: Database Hugging Disorder, defined by Hans Rosling at World Bank Open Data speech in May 2010. The cure of this disease can be offered as linked open data, which contains ontologies for health science, diseases, genes, drugs, GEO species etc. LOD-Linked Open Data provides the systematic application of information by publishing and connecting structured data on the Web. In the context of this study we aimed to reduce boundaries between semantic web and geo web. For this reason a use case data is studied from Valencia CSISP- Research Center of Public Health in which the mortality rates for particular diseases are represented spatio-temporally. Use case data is divided into three conceptual domains (health, spatial, statistical), enhanced with semantic relations and descriptions by following Linked Data Principles. Finally in order to convey complex health-related information, we offer an infrastructure integrating geo web and semantic web. Based on the established outcome, user access methods are introduced and future researches/studies are outlined.

Повний текст джерелаAir pollution is a critical issue in contemporary times. For this reason, officials and environmental managers are in need of suitable tools for visualization, manipulation and analysis of environmental data. Environmental concerns in Europe have encouraged the European Environmental Agency (EEA) to create the European Pollutant Release and Transfer Register (E-PRTR). The E-PRTR is vital and valuable because society will benefit if the data are used to improve monitoring and consequently advance environmental management. However, the data are not accessible in an interoperable way, which complicates their use and does not allow for a contribution to environmental monitoring. This paper describes a Web GIS system developed for the monitoring of industrial emissions using environmental data released by the EEA. Four research objectives are addressed: (1) design and create an interoperable spatial database to store environmental data, (2) develop a Web GIS to manipulate the spatial database, facilitate air pollution monitoring and enhance risk assessment, (3) implement OGC standards to provide data interoperability and integration into a Web GIS, (4) create a model to simulate distribution of air pollutants and assess a population’s exposure to industrial emissions. The proposed approach towards interoperability is an adoption of servicebased architecture for implementation of a three-tier Web GIS application. This system’s prototype is developed using open source tools for the Valencian Community of Spain.

Spatial analysis through visualization, exploration and modelling allow for a deeper comprehension of the spatial and temporal dynamics of diseases and may be used to suggest and support epidemiologic hypotheses. The Internet is nowadays the preferred means for the electronic sharing of data and it still evolving. Its advent has also pushed for the development of powerful proprietary and Open Source (OS) technologies to provide a standard platform for the management, visualization and analysis of spatial epidemiologic data.

Повний текст джерелаIn the Ethiopian rural region of Amhara, variable atmospheric conditions and climate change are affecting the agricultural productivity and the consequences might be irreversible. However, scientific and technological advances nowadays can be more and more helpful to improve the situation. The purpose of the present work is to build the effective strategies that permit the utilization and integration of GIS technologies in the institutional and humanitarian works that are being carried out in the region. Our challenge will be to raise the geographical awareness and optimize the use of resources and tools in the region, involving the farmer communities as key stakeholders in the whole process. The work explains the first steps taken regarding the necessity of building GIS capacity for risk mapping, the data collection related to food security and the use of GIS technologies, being the training of the local staff the key point that leads to further steps such as the implementation of the mechanisms to share spatial information known as Spatial Data Infrastructures. By using SDI, combined with GIS software to access and manage the information, we may improve the understanding and interoperable utilization of geo-spatial data, and therefore contribute to the development of such a needy nation. All that, developed under the umbrella of an Inter-University Cooperation Program.
