Sensor network infrastructure for intelligent building monitoring and management system

Dymora P., Mazurek M., Nieroda S.

The aim of this study was to present that it is possible to design and implement an efficient and functional intelligent building management system based on free tools, own project and self-realization of sensor network system which may be a low cost alternative to commercial ones. The paper presents the designed system consisting of implemented devices on the basis of sensor network technology and own hardware project in a building management system. At the application level there was designed and implemented the building management system which allows communication between the sensors, data exchange between the sensors and the database as well as the system parameters visualization panel used for intelligent building monitoring.

Long-range dependencies in reading memory pages in the man-computer system interaction

This paper shows that the organization of computer system memory as a hierarchical structure can lead to the existence of long-memory effect during the man-computer interaction. As a point of reference, the rate at which the operating system resolves data from hard drive caused by the hardware page faults in the virtual memory mechanism can be given. The existence of such a phenomenon can be considered in terms of statistical mechanics and Hurst parameter.
