13. Automatic dependent surveillance on air traffic control: risk assessment based on fluid stochastic Petri nets modeling. / Vigilância dependente automática no controle de tráfego aéreo: avaliação de risco baseada em modelagem em redes de Petri fluidas e estocásticas.
In last decades, the safety critical systems paradigm has changing to adapt itself to new necessities, such as costs reduction and productivity demand growth. In the Air Traffic System, those changes are ruled by CNS/ATM paradigm (Communication, Navigation, Surveillance / Air Traffic Management), based on new digital Technologies, mainly Satellites, applied

14. SISTEMA DE CONTAGEM DE PESSOAS / PEOPLE COUNTING SYSTEM
There is worldwide an increasing concern about security issues. A great deal of efforts have been undertaken in order to provide surveillance systems. This work proposes an automatic method to determine the number of people moving in an area monitored by a video camera, as well as to detect image changes, which are potentially due to illicit attitudes. A typ

15. Desenvolvimento de um protÃtipo de simulador para monitoramento e vigilÃncia do espaÃo aÃreo.
O presente trabalho propÃe uma Abordagem de Monitoramento e VigilÃncia do EspaÃo AÃreo para a RegiÃo AmazÃnica. A AmazÃnia ocupa mais 50% do territÃrio brasileiro e possui Ãreas inÃspitas e cobiÃadas internacionalmente. As tecnologias de VigilÃncia, com base nos conceitos de ComunicaÃÃo, NavegaÃÃo e VigilÃncia para o Gerenciamento do TrÃfeg

16. Tecnicas de rastreamento e aplicações em analise cinematica de movimentos humanos
The problem of tracking objects from a sequence of video images has been of great interest in the recent years. This interest is motivated, especially, by the wide range of applications such as virtual reality surveillance systems, robotic, human motion analysis, etc. In the human motion analysis, the kinematic variables, (e.g., the covered distance, velocit

17. Computerized surveillance in clinical microbiology with time series analysis.
An automatic surveillance system to detect changes in the incidences of microorganisms diagnosed in the department of clinical microbiology has been developed. The program is incorporated into the laboratory computer system and gives a weekly list of microorganisms whose isolation rates compared with those of a previous period exceed a chosen limit. The syst

18. Rapid micromethod of screening for antibodies to disease agents using the indirect enzyme-labeled antibody test.
We have developed a rapid and simple indirect enzyme-labeled antibody procedure suitable for screening for antibodies to viral, bacterial, and parasitic antigens. Disposable microplates were utilized as antigen carriers and test vehicles. The test worked equally well with serum or whole unclotted blood. Using an automatic pipettor, 96 tests could be performe

19. Screening of Active Lyssavirus Infection in Wild Bat Populations by Viral RNA Detection on Oropharyngeal Swabs
Brain analysis cannot be used for the investigation of active lyssavirus infection in healthy bats because most bat species are protected by conservation directives. Consequently, serology remains the only tool for performing virological studies on natural bat populations; however, the presence of antibodies merely reflects past exposure to the virus and is

20. UK Naval Dockyards Asbestosis Study: radiological methods in the surveillance of workers exposed to asbestos
ABSTRACT In a survey of the effects of exposure to asbestos in the UK Naval Dockyards, small- and large-film chest radiographs of 674 men have been examined. These films have been read under survey conditions by two readers using a simple screening classification, and also in a controlled trial by five readers using the full ILO U/C classification.
