A pattern language for fire alarm systems
After an object-oriented framework for micro-processor based fire alarm systems had been implemented and the first instantiated system had reached product status an effort was undertaken to clearly document the architecture embedded in the framework. The result of this effort was a small pattern language which is presented in this paper. Important patterns in this language are the Point pattern...

It is imperative, therefore, that people receive content that is comprehensible. Such understanding can be influenced by the message itself, the talker and liste...

It sends early alarm when the fire occurs and helps to reduce the fire damage. Wireless sensor network has become the most important technology in environmental monitoring and home or factory automation in recent years. In this paper, an automatic f...
متن کاملAn Automatic Detection of the Fire Smoke Through Multispectral Images
One of the consequences of a fire is smoke. Occasionally, monitoring and detection of this smoke can be a solution to prevent occurrence or spreading a fire. On the other hand, due to the destructive effects of the smoke spreading on human health, measures can be taken to improve the level of health services by zoning and monitoring its expansion process. In this paper, an automated method is p...
متن کاملNew alarm bells
Some species do appear to practise construction skills — birds in particular — and to require some mental flexibility in starting the process. But ultimately, animals build the way they do because they are genetically programmed to do so, Hansell concludes. But evolution can lead to surprising results. Hansell notes that most of our closest primate relatives create little more than temporary sh...
