Komparativ analys av HTTP och AMQP i System Wide Information Management / Comparative analysis of HTTP and AMQP in System Wide Information Management

Håkansson, Anna January 2024 (has links)
Med en ökande tillväxt inom flygtrafikbranschen behöver de bakomliggande flygtrafikledningssystemen uppgraderas för att möta den växande komplexiteten i syfte att säkerställa en ordnad flygtrafik. Här anses det arkitekturella konceptet System Wide Information Management (SWIM) för distribuerade flygledningssystem vara lösningen för att bygga system som är lättare att underhålla och enklare kan kan samverka med varandra. År 2021 fastslog Europeiska unionen att samtliga operativa intressenter inom det aeronautiska informationsutbytet i EU skall tillhandahålla och kunna konsumera SWIM-tjänster och erbjöd då en uppsättning tjänstegränssnittsbindningar för intressenter att hävda foglighet med för att efterfölja de nya regleringarna. Bland dessa finner vi AMQP Messaging och WS Light som utiliserar AMQP respektive HTTP som meddelandeprotokoll. Tidigare forskning har visat att AMQP presterar bättre än HTTP inom de flesta områden, men denna studie undersöker om någon av de två lämpar sig bättre som meddelandeprotokoll för en europabaserad SWIM-implementation genom att analysera resultatet i en SWIM-kontext. Med hjälp av en komparativ analys och kvantitativ dataanalys jämförs de två meddelandeprotokollen i denna studie för att identifiera liknande och åtskiljande karaktärsdrag samt för att svara på om någon av de två lämpar sig bättre för ändamålet. De punkter protokollen jämförs på är struktur, overhead och effektivitet, interoperabilitet och kompabilitet, tillförlitlighet och feltolerans samt förekomster i Eurocontrols SWIM Registry. Studiens resultat visar att AMQP är den lämpligaste kandidaten av de två sett till implementationstrender och prestanda, men att det är bör göras en avvägning innan en intressent väljer vilket gränssnitt denne skall implementera. / With an increasing growth within the aviation industry, the underlying air traffic control systems needs to be upgraded to meet the growing complexity for ensuring an organized air traffic. This is where the architectural concept System Wide Information Management (SWIM) for distributed air traffic control systems is believed to be the solution for building systems that are easier to maintain and can cooperate with ease. In the year 2021, the European Union decided that all operative stakeholders within the aeronautical information exchange in EU shall provide and be able to consume SWIM services, and provided a set of service interface bindings for stakeholders to claim conformance to in order to follow the new regulations. Among these we find AMQP Messaging and WS Light that utilizes AMQP and HTTP, respectively, as messaging protocols. Previous research has shown that AMQP performs better than HTTP in most areas, but this study analyses the result in a SWIM context to see if any of the two is a more suitable messaging protocol in a Europe based SWIM implementation. Through a comparative analysis and a quantitative data analysis the two messaging protocols are compared in this study to identify similar and distinctive characteristics to answer whether one of the two is a better candidate for the purpose. The protocols are compared on their structure, overhead and efficiency, interoperability and fault tolerance, and their occurances in Eurocontrol's SWIM Registry. The result of the study shows that AMQP is the more suitable candidate of the two, in regards to trends in current implementations as well as performance metrics, but a stakeholder should make a trade-off before choosing what service interface binding to implement.

Candido, Humberto Gois. January 2008 (has links)
Orientador: João Antonio Galbiatti / Banca: Teresa Cristina Tarlé Pissarra / Banca: Marcilio Vieira Martins Filho / Banca: David Luciano Rosalen / Banca: Raimundo Leite Cruz / Resumo: O presente estudo trata da avaliação da degradação ambiental da bacia do rio Uberaba, situada no Triângulo Mineiro. Esta bacia possui área de 2.419,04 km2, abrange os municípios de Uberaba, Veríssimo, Conceição das Alagoas e uma pequena porção de Planura. Neste estudo foi produzido o mapa de degradação ambiental contendo quatro níveis: baixo; moderado; acentuado e severo. Os indicadores utilizados nesta avaliação foram: vegetação; topografia; solo/geologia; potencial natural de erosão; mecanização; área agrícola; densidade populacional; pecuarização e área de conflito, aos quais foram atribuídos pesos. Para o nível de degradação "baixo" foram definidos valores <=13 pontos. Para o nível "moderado", valores situados no intervalo de 14 a 16. Entre 17 a 19 pontos para o nível "acentuado", e o nível "severo" com valores >= 20 pontos. Este estudo consolida as conseqüências do uso inadequado dos solos, não respeitando as suas aptidões naturais. As áreas com nível moderado representam 46,97 %. As áreas classificadas com nível acentuado 47,96 %, e severo 4,10 %; juntas, representam 52,06 %, o que revela um indício muito forte no avanço da destruição dos recursos naturais. As áreas classificadas com nível baixo representam apenas 0,97 %, com destaque para o descaso na preservação dos seus recursos naturais. / Abstract: The present study deals with the assessment of the environmental degradation of the river basin Uberaba, located in the Triangle Mineiro. This basin has area of 2,419.04 km2, covering the municipalities of Uberaba, Veríssimo, Conceição of the Alagoas and a small portion of Planura. In this study, the map of environmental degradation was produced contend four levels: low; moderate; accented and severe. The indicators used in this evaluation had been: vegetation; topography; soil/geology; natural potential of erosion; mechanization; agricultural area; population density; cattleraising and area of conflict, which were assigned weights. For the level of degradation "low" were defined values <=13 points. To level the "moderate", values located i n the range of 14 a 16. It enters 17 a 19 points for "the accented" level, and the level "severe" with values >= 20 points. This study consolidates the consequences of the inadequate use of land, not respecting their natural aptitudes. Areas with moderate level represent 46.97 %. The areas classified with accented level marked with 47.96 %, and severe 4.10 %; together, represent 52.06 %, which shows a very strong indication in the advance of the destruction of the natural resources. The areas classified with low level represent only 0.97 %, with emphasis on the neglect the preservation of its natural resources. / Doutor

O presente estudo teve como objetivos caracterizar o perfil dos profissionais médicos que atuam nas ESFs dos municípios da área de abrangência da DIR XVIII, Ribeirão Preto, SP e a utilização do Sistema de Informação da Atenção Básica por este profissional, no seu trabalho na Equipe de Saúde da Família. Utilizou-se um estudo tipo Survey, no qual a coleta de dados foi realizada por meio de questionários auto-administrados compostos por perguntas de respostas fechadas, do tipo múltipla escolha, perguntas de respostas tipo abertas e perguntas que utilizavam a Escala de Avaliação Gráfica. A análise dos resultados possibilitou a caracterização do perfil dos profissionais, na maioria do sexo masculino (60%), em média com 38 anos de idade, possuidor de pós-graduação (85%), predominantemente do tipo lato sensu, concentrada em residência e especialização nas áreas de clínica médica, pediatria e ginecologia. Os profissionais tinham em média 11 anos de profissão, encontrando-se na fase de afirmação profissional e atuando há cerca de 03 anos em PSF. A maioria possuindo vínculos empregatícios precários sem estabilidade (61%), trabalhando em outros locais além do PSF (65%). Os profissionais referiram conhecer o SIAB (85%), com um grau de conhecimento, em média, de 53% e possuírem uma visão positiva sobre ele, atribuindo-lhe muita importância para o desenvolvimento do seu trabalho na Equipe de Saúde da Família, em média 64,89%, e para a caracterização da população atendida, em média 62,78%, merecendo ressalvas de vários profissionais quanto à limitação do sistema em relação aos dados coletados a nível local. A necessidade de treinamento foi relevada como possibilidade de capacitação na busca por um maior conhecimento no uso do sistema. Do total de respondentes, apenas 29,4% referiram ter feito treinamento. Outro ponto importante referia-se à readequação da agenda de atividades da ESF, com o objetivo de proporcionar a efetivação de um espaço de discussão acerca do sistema e às informações por ele geradas. O autor acredita que com a implementação de propostas emergidas de um estudo entre os diversos atores envolvidos no processo saúde-doença, em que sejam contemplados não somente os profissionais de linha de frente, mas também coordenadores e gestores e principalmente os usuários, será possível atingir níveis de qualidade melhores em relação às informações geradas pelo sistema e assim se poderão propor e efetivar ações que busquem o alcance do objetivo maior, que é o de atender a população com mais qualidade e, conseqüentemente, proporcionar uma melhor qualidade de vida para o cidadão. / The present study has as objective to characterize the profile of the medical professionals who act in the ESFs of the cities of the geographic area of DIR XVIII, Ribeirão Preto, SP and the use of the System of Information of the Basic Attention for this professional, in its work in the Team of Health of the Family. It was used a type of study Survey, in which the collection of data was carried through by means of auto-managed questionnaires composites for questions of closed answers, of the multiple type choice, questions of open answers type and questions that used Graphical Evaluation Scale. The analysis of the results made possible the characterization of the profile of the professionals, in the majority of the masculine sex (60%), on average with 38 years of age, and of after-graduation (85%), predominantly of the type lato sensu, intent in residence and specialization in the areas of medical clinic, pediatrics and gynecology. The professionals had on average 11 years of profession, meeting in the phase of professional affirmation and acting about 3 years in PSF. The majority possessing precarious employment bonds without stability (61%), working in other places beyond the PSF (65%). The professionals had related to know the SIAB (85%), with a knowledge degree, on average, of 53% and to possess a positive vision on it, attributing much importance to it for the development of its work in the Team of Health of Family, on average 64.89%, and for the characterization of the taken care of population, on average 62.78%, deserving exceptions of some professionals how much the limitation of the system in relation to the collected data locally. The training necessity was raised as possibility of qualification in the search for a bigger knowledge in the use of the system. Of the total of respondents, only 29.4% had related to have done training. Another important point mentioned referred to needs adjusting the agenda of activities of the ESF, with the objective to provide time to discuss about the system and the information it generated. The author believes that with the implementation of emerged proposals of a study he enters the diverse involved actors in the process health-illness, where is contemplated not only the professionals of front line, but coordinating and also managing and mainly the users, the information generated for the system will be possible to reach better levels of quality in relation and thus if it will be able to consider and to accomplish action that they consequently search the reach of the main objective, that is to take care of the population with more quality, and, to provide a better quality of life for the citizen.

The role of system administrators in information systems success

Edlund, Sara, Lövquist, Andreas January 2012 (has links)
Limited research has been conducted on how system administrators actually can affect information systems (IS) after they have been implemented; hence, this study examines how system administrators can affect IS success in an implemented IS. The study identified a system administrator´s affect on the three IS quality dimensions in the DeLone and McLean IS success model. The empirical findings was based on a single case study where the data was collected through interviews with the system administrator and the system assistants, but also through a questionnaire answered by the users of the IS. The empirical findings suggested that the system administrator can affect IS success through the IS quality dimensions both directly and indirectly. The system administrator´s affect on IS success proved to be highly dependent on the external system vendor and the structure of the internal support unit.

A study on the adoption and diffusion of information and communication technologies in the banking industry in Thailand using multiple-criteria decision making and system dynamics approaches.

Intrapairot, Arunee January 2000 (has links)
The main objective of this study is to develop requisite models for information and communication technology (ACT) adoption and diffusion in the banking industry in Thailand. The research, combining two study areas of multiple criteria decision-making (MCDM) and system dynamics (SD), is conducted using two research methodologies: system development and a case study of the Siam Commercial Bank PCL in Thailand.The study shows how to combine the two decision-making tools of MCDM and system dynamics effectively. The requisite group models of ICT adoption and diffusion provide ways to select the most preferred technology and to allow forward planning to diffuse the adopted technology more effectively. With an embedded decision support tool, decision-makers are able to apply the models with their available information, intuition, knowledge, and experience to improve their decision-making and enhance their learning.Initially, the research revealed that the Siam Commercial Bank currently employs various types of information and communication technologies (ICT) to facilitate work processes, fulfil customers' requirements, and retain its competitive advantage. However, the bank still confronts problems relating to technology adoption and diffusion.A requisite group model of ICT adoption was developed using MCDM as a decision making tool. The model illustrated how to select the most preferable technological alternative that fulfilled the mission of the bank. Results from the MCDM analysis revealed that the preferred technology was Extranet banking followed by a data warehouse. The requisite group model of ICT diffusion was further developed using the system dynamics approach in order to enhance understanding of system behaviour of the selected technology and then provide ways to diffuse it more effectively. The model analyses were divided into three sub-models of information ++ / and communication technologies (ICT), a data warehouse, and Extranet banking.The generic model of ICT can be applied to any particular technology. Results revealed that the pattern of technology diffusion follows the S curve and the dominant variables that may impact on technology diffusion are training, a backlog of problems, and market potential. Furthermore economic returns are obtained only after spending substantially on technological investment. Thus, it is necessary to balance between technological investment and economic returns. The model of diffusion of a data warehouse was developed highlighting the necessity of quality and quantity of knowledge workers. Therefore, training support is an important factor to diffuse this technology. On the other hand, the model of diffusion of Extranet banking revealed that the success of this technology comes from the acceptance by customers. Thus, perceived relative advantages, positive features of the technology and promotional advertising should be taken into consideration. The S curve pattern of technology diffusion is also confirmed by the two technologies.The policy for technology adoption involves the selection of technology, which best fits with identified criteria. The policy analyses of the three technologies confirm that the core important policies that increase technology diffusion and economic gains are increasing positive features of technology, decreasing perceived complexity, increased perceived relative advantages and increasing co-operation between IT people and users. If technology is to support the work performance in an organisation, training support is the dominant policy, whereas if technology facilitates customers directly, marketing strategy such as promotional advertising is vital.The study implied that the banking industry in Thailand is able to use ICT as levers for competitive advantage. ++ / However, technological investment in each bank differs depending on size, objectives and readiness in terms of capital and human resources.All the findings have implications for the bank and could be applied to other banks and general policy makers in various business enterprises.
