Gerenciamento de Threads - Slides

O material apresenta o gerenciamento de threads no Windows. Um sistema operacional envolve atividades assíncronas e algumas vezes paralelas, sendo que a noção de processo de software é usada em sistemas operacionais para expressar o gerenciamento e controle de suas atividades. Processo é um dos conceitos fundamentais no projeto de um sistema operacional moderno. Threads podem ser gerenciados pelo sistema operacional ou pela aplicação do usuário. Além desses conceitos, o material destaca a motivação para o uso de threads; o parâmetro CreateThread; e a prioridade e escalonamento.

Gerenciamento de alarmes em plataformas marítimas de produção de hidrocarbonetos: metodologia e estudo de caso

In the operational context of industrial processes, alarm, by definition, is a warning to the operator that an action with limited time to run is required, while the event is a change of state information, which does not require action by the operator, therefore should not be advertised, and only stored for analysis of maintenance, incidents and used for signaling / monitoring (EEMUA, 2007). However, alarms and events are often confused and improperly configured similarly by developers of automation systems. This practice results in a high amount of pseudo-alarms during the operation of industrial processes. The high number of alarms is a major obstacle to improving operational efficiency, making it difficult to identify problems and increasing the time to respond to abnormalities. The main consequences of this scenario are the increased risk to personal safety, facilities, environment deterioration and loss of production. The aim of this paper is to present a philosophy for setting up a system of supervision and control, developed with the aim of reducing the amount of pseudo-alarms and increase reliability of the information that the system provides. A real case study was conducted in the automation system of the offshore production of hydrocarbons from Petrobras in Rio Grande do Norte, in order to validate the application of this new methodology. The work followed the premises of the tool presented in ISA SP18.2. 2009, called "life cycle alarm . After the implementation of methodology there was a significant reduction in the number of alarms
