AUTOMATED IMAGE LOCALIZATION AND DAMAGE LEVEL EVALUATION FOR RAPID POST-EVENT BUILDING ASSESSMENT

Xiaoyu Liu (13989906) 25 October 2022 (has links)
<p>    </p> <p>Image data remains an important tool for post-event building assessment and documentation. After each natural hazard event, significant efforts are made by teams of engineers to visit the affected regions and collect useful image data. In general, a global positioning system (GPS) can provide useful spatial information for localizing image data. However, it is challenging to collect such information when images are captured in places where GPS signals are weak or interrupted, such as the indoor spaces of buildings. An inability to document the images’ locations would hinder the analysis, organization, and documentation of these images as they lack sufficient spatial context. This problem becomes more urgent to solve for the inspection mission covering a large area, like a community. To address this issue, the objective of this research is to generate a tool to automatically process the image data collected during such a mission and provide the location of each image. Towards this goal, the following tasks are performed. First, I develop a methodology to localize images and link them to locations on a structural drawing (Task 1). Second, this methodology is extended to be able to process data collected from a large scale area, and perform indoor localization for images collected on each of the indoor floors of each individual building (Task 2). Third, I develop an automated technique to render the damage condition decision of buildings by fusing the image data collected within (Task 3). The methods developed through each task have been evaluated with data collected from real world buildings. This research may also lead to automated assessment of buildings over a large scale area. </p>

No. of bitstreams: 1 Antonio Reinaldo Rabelo Filho.pdf: 1182565 bytes, checksum: 04d7e2e5109cb7d7b401525d148c9d80 (MD5) Previous issue date: 2009-12-21 / The present study aims at ascertaining the specific aspects regarding the levying of the Tax on Communication Services, by means of distinguishing between the service communications tax s event of assessment s nucleus to provide communication services and other related conducts. Subsequently, we also analyze the tax system in order to outline the premises needed to comprehend the Tax on Communication Services event of assessment. By means of these studies, we conclude that to provide communication services , as said tax s event of assessment s nucleus, must be understood as the conduct of offering the necessary and sufficient conditions to transport a message. Furthermore, we define the concepts of radio broad-casting, publicity and paid television, in order to conclude that radio broad-casting is taxed by the Tax on Communication Services. Regarding to publicity and advertising, the tax doesn´t levy on their production but only on the service rendered for their transportation if it was the utility hired. However, we understand that paid television, when monthly paid for by its users, does not meet the necessary requirements to be levied by the Tax on Communication Services. Regarding the telecommunication services, we initiated our research with an overview of the Brazilian telecommunications system prior to the privatization process, which resulted in the General Telecommunications Law GTL. Afterwards, we focused on the utilities and features provided by not only the communication service providers, but also of those provided by third-parties. From this we noticed that when there is economic autonomy and private usage, put at the user s disposal by means of an affirmative obligation established in law, the correct event of assessment is that of the Service Tax. However, it is necessary to previously verify if it is something accessory and contemplated in the concept of offering the necessary and sufficient means of transporting messages from third-parties, in return for payment. If the answer is positive than the activity may be levied by the Tax on Communication Services. Lastly, we conclude that it is necessary to dissociate the utilities offered by means of the internet, or even cellular phones, from the concept of providing services, which is the event of assessment of the Tax on Communication Services and of the Service Tax, insofar as the assignment of the rights pertaining to a program or content, even if only on a temporarily basis, does not align itself with the conduct of executing said content or of transporting it to a third-party. In brief, we understand that the correct comprehension of each of the legal relationships displayed will give the interpreter the necessary instruments to define the applicable tax norms / O objetivo do presente trabalho é estabelecer os contornos específicos da regra-matriz de incidência tributária do imposto sobre prestação dos serviços de comunicação, a partir da diferenciação entre o conceito atinente ao núcleo da hipótese de incidência prestar serviços de comunicação e outras realidades por vezes conexas. Posteriormente, estudamos o sistema tributário e fixamos as premissas para a compreensão da regra-matriz de incidência tributária do ICMS-comunicação. A partir dessas considerações, concluímos que prestar serviço de comunicação , como núcleo da hipótese de incidência da referida exação, precisa ser entendido como a atividade de oferecer as condições necessárias e suficientes para que uma mensagem seja transportada. Mais adiante, definimos os conceitos de serviços de radiodifusão, publicidade e TV por Assinatura, para concluir que a prestação dos serviços de radiodifusão são tributados pelo ICMS-comunicação. Quanto ao serviços de publicidade e propaganda, o imposto não incide sobre a sua produção, mas sobre os serviços oferecidos para o seu transporte ou veiculação, se for essa a utilidade contratada. Para a TV por assinatura, remunerada via prestação mensal cobrada dos seus usuários, entendemos que a materialidade não reúne as notas suficientes para ser incluída no espectro de incidência do ICMS-comunicação. Sobre os serviços de telecomunicações, iniciamos nossa pesquisa com um escorço histórico acerca do sistema de telecomunicações brasileiro antes do processo de privatização, que culminou com a edição da Lei Geral das Telecomunicações LGT. Após, nos dedicamos a analisar o oferecimento de utilidades e funcionalidades não apenas por parte das próprias operadoras dos serviços de comunicação, mas também por terceiros. Com isso percebemos que, onde se vislumbrar autonomia econômica e utilidade própria, posta à disposição por intermédio da realização de um fazer prevista na legislação de regência, está-se diante da hipótese de incidência do ISS. Todavia, é necessário, antes, perceber se está-se diante de algo acessório e inserido no conceito de disponibilização dos meios necessários e suficientes para transporte de mensagens de terceiros, mediante pagamento. Se positiva a resposta, estaremos diante de realidade que pode ser tributada pelo ICMS. Por fim, concluímos que é preciso que se afaste do conceito de prestação de serviços, hipótese de incidência do ICMS ou do ISS, as utilidades oferecidas por meio da internet ou mesmo aparelhos celulares. Isso porque a cessão do direito de uso de um programa ou conteúdo, ainda que de forma temporária, não se compagina com a atividade de executar aquele conteúdo ou de transportá-lo a terceiro. Em resumo, entendemos que o correto entendimento de cada uma das relações jurídicas postas é que dará ao aplicador o cabedal necessário para a definição da norma tributária aplicável
