In this paper, an empirical evaluation of acoustical signals for leakage detection and quantification in underground plastic pipes for main water distribution networks is presented. Several experiments have been carried out to collect acoustic signals generated from various leakage volumes. Upon signals analysis, it is noticed that the acquired signals are so weak and they are buried in the background...
In this paper, an actual deployment of a wireless sensor network is described. The purpose of the sensor network is to monitor and analyze air quality in Doha. Small scale wireless sensor stations communicate with a backend server to relay their measurements in real-time. Data stored on the server is subjected to intelligent processing and analysis in order to present it in different formats for different...
This paper presents an ambient real-time air quality monitoring system. The system consists of several distributed monitoring stations that communicate wirelessly with a backend server using machine-to-machine communication. Each station is equipped with gaseous and meteorological sensors as well as data logging and wireless communication capabilities. The backend server collects real time data from...
Stand alone wind-Diesel power systems can be an attractive solution for the supply of remotely located consumers or the provision of enhanced energy independence particularly in the Near-East region. This paper presents a dynamic behavior of a hybrid power system containing a wind turbine induction generator and a Diesel generator set supplying electrical demands for the main hospital in Gaza-Strip...
Hybrid wind-Diesel systems can be an attractive solution for the supply of remotely located consumers or the provision of enhanced energy independence in the Near-East region, especially in Gaza strip. Such stand-alone system contains a wind turbine, batteries as short term storage as well as hydrogen storage tanks as long term storage devices. The proposed system leads to a remarkable reduction in...
