No full textGeneral simulated scenes
These scenes followed a pre-defined script (see the Thesis for details), with common movements corresponding to general experiments. People go to or stand still in front of "J9", and/or go to the side of Argonauta reactor and come back again.
The first type of movement is common during Irradiation experiments, where a material sample is put within the "J9" channel; and also during neutrongraphy or gammagraphy experiments, where a sample is placed in front of "J9". Here, the detailed movements of putting samples on these places were not reproduced in details, but only the whole bodies' movements were simulated (as crouching or being still in front of "J9").
The second type of movement may occur when operators go to the side of Argonauta to verify some operational condition.
- Scene 1 (Obs.: Scene 1 of the "General simulated scenes" class):
Comprises one of the scenes with two persons. Both of them use clothes of light colors. Both persons remain still in front of "J9"; one goes to the computer and then come back, and both go out.

No full textScenes for Spectrography experiment
Scenes were recorded following the tasks involved in spectrography experiments, which are carried out in front of "J9" output radiadion channel, the latter in open condition. These tasks may be executed by one or two persons. One person can do the tasks, but requiring him to crouch in front of "J9" to adjust the angular position the experimental appartus (a crystal to bend the neutron radiation to the spectograph), and then to get up to verify data in a computer aside; these movements are repeated until achieving the right operational conditions. Two people may aid one another in such a way one remais crouched while the other remains still in front of the computer. They may also interchange tasks so as to divide received doses.
Up to now, there are available two scenes with one person and one scene with two persons. These scenes are described in the sequel:
- Scene 1:
Comprises one of the scenes with one person performing spectography experiment.

Argonauta Video Database: Projection and Homography matrices. Projection Left Camera
No full textDescription of the Annotation files:
Annotation files are supplied for each video, for benchmarking. Annotations correspond to ground truths of peoples' positions in the image plane, and also for their feet positions, when they were visible.
Annotations were performed manually, with the aid of a code developed by (Silva et al., 2014; see the Thesis for details). Targets (people or feet) are marked at variable frame intervals and then linearly interpolated

Avaliação e Otimização de um Tanque Decantador de Placas Paralelas Verticais Empregando-se Traçadores Radioativos
Get PDFÉ apresentada metodologia para estudos e avaliações em tempo real, de unidades para dedantação de particulados sólidos em estações de tratamento de esgoto (ETE) empregando-se traçadores radioativos. Um tanque decantador foi construído e os testes foram realizados usando-se 110mAg e 140La na marcação da fase sólida do esgoto e a técnica permitiu levantar-se a curva resposta da unidade e as funções distribuição do tempo de residência (RTD) para diversas situações experimentais e também identificar problemas operacionais que interferem na qualidade final do processo de tratamento do efluente. Os resultados serviram como diretriz para elaborar uma nova configuração da unidade, tornando-a mais eficiente
A mobile computer system to support first responders to a radiological emergency
Get PDFDecision-making in emergency situations is characterized by its speed, pressure, and especially the uncertainty of information. Uninformed decisions or decisions based on unreliable data may lead to inappropriate actions. Although several studies that aim to combine different databases and provide full information to emergency response operation commanders can be found, only few of them are dedicated to radiological emergencies situations and even less are those that aim to provide support for the emergency first responder. We developed a system to support first responders to deal with radiological emergencies using cognitive task analysis techniques to elicit the tacitly knowledge of practitioners to grasp what information is really needed during radiological emergency response

Análise da disponibilidade da instrumentação nuclear de um reator de pesquisa
Get PDFThe maintenance of systems and equipment is a central question related to
Production Engineering. Although systems are not fully reliable, it is often necessary to
minimize the failure occurrence likelihood. The failures occurrences can have disastrous
consequences during a plane flight or operation of a nuclear power plant. The
elaboration of a maintenance plan has as objective the prevention and recovery from
system failures, increasing reliability and reducing the cost of unplanned shutdowns.
It is also important to consider the issues related to organizations safety, especially
those dealing with dangerous technologies.
The objective of this thesis is to propose a method for maintenance analysis of a
nuclear research reactor, using a socio-technical approach, and focused on existing
conditions in Brazil. The research reactor studied belongs to the federal government and
it is located in the city of Rio de Janeiro. The specific objective of this thesis is to
develop the availability analysis of one of the principal systems of the research reactor,
the nuclear instrumentation system. In this analysis, were taken into account not only
the technical aspects of the modules related to nuclear instrumentation system, but also
the human and organizational factors that could affect the availability of the nuclear
instrumentation system. The results showed the influence of these factors on the
availability of the nuclear instrumentation system.A manutenção de sistemas e equipamentos é uma questão central na Engenharia
de Produção. Embora nenhum sistema seja imune a falhas, geralmente é necessário
minimizar a probabilidade delas ocorrerem. A ocorrência de falhas pode ter
consequências desastrosas como num vôo de um avião ou na operação de uma usina
nuclear. A elaboração de um plano de manutenção tem por objetivo a prevenção e
recuperação das falhas do sistema, aumentando a confiabilidade deste e diminuindo os
custos decorrentes das paradas não planejadas. É fundamental também para as questões
relacionadas à segurança das organizações, principalmente naquelas que lidam com
tecnologias perigosas.
Esta tese tem por objetivo propor um método para a análise da manutenção de
um reator nuclear de pesquisa, utilizando uma abordagem sócio-técnica, e com foco nas
condições existentes atualmente no Brasil. O reator de pesquisa estudado pertence a um
órgão público, localizado na cidade do Rio de Janeiro. A proposta da tese se consistiu
em analisar a disponibilidade de um dos principais sistemas que fazem parte do reator
de pesquisa, o sistema de instrumentação nuclear. Nesta análise, foram levados em
consideração não apenas os aspectos técnicos dos módulos que compõem o sistema de
instrumentação nuclear, mas também os fatores humanos e organizacionais que
poderiam afetar a disponibilidade deste sistema. Os resultados obtidos mostraram a
influência destes fatores na disponibilidade do sistema de instrumentação nuclear
