A wide measurement range is obtained using the pulsed-power-decay transmission technique, and regardless of the material used to construct the container. A signal in the receiver transducer provides the attenuation measurements, for each echo, a fast Fourier transform (FFT) of the appropriate signal was obtained and compared with the water signals to yield the attenuation as a function of frequency. The data show the feasibility of measuring a kaolin concentration of 5% wt. When using a commercial pulser with the same device setting, no detectable echo was observed. Therefore, new technique measurements may prove useful in detecting solid content in liquid. This study demonstrated that the proposed pulsed-power transmission technique is promising for evaluating low concentrations of solids in fluids and for measuring sedimentation in solid-liquid systems.

As well as scattered area and belonging. This research presents a Real-Time intruder Surveillance System based on a single board computer (SBC). Thus the design and development of a cost effective surveillance management system based SBC that can be deployed efficiently in remote and scattered locations such as universities belonging. The fusion of embedded Python codes with SBC that attached to cameras, Long distance sensors, alerting circuitry and wireless module presents a novel integration based effective cost solution and enhances SBC of much flexibility of improvement and development for pervasive remote locations. The system proves the high integrity of smooth working with web application, it's cost effective and thus can be deployed as many of units to seize and concisely covered remote and scattered area as well as university belonging and departments. The system can be administrated by a remote user sparsely or geographically away from any networked workstation. The proposed solution offers efficient stand alone, flexibility to upgrade and cheap development and installation as well as cost effective ubiquitous surveillance solution. In conclusion, the system acceptable boundaries of successful intruder recognition and warning alert are computed between 1m and 3m distance of intruder from system camera. Recognition rate of 95% and 83% are achieved and the successful warning alert were in the range of 86-97%.

This paper provides an experimental description of a smart algorithm in which the sensitivity node operates. The specification is based on measuring the current that is discharged from the power source in data transmissions. The measurements allow for the definition of an analytical model for the number of data packets to be sent from the terminal sensor node, a function of sensor operation and the level of change of sensor data. Conventional sensor nodes are not effective in terms of productivity, flexibility, energy consumption and work interference. The sensor node is programmed according to the conventional method, which sends the data every minute, and then reprogrammed according to the intelligent algorithm in which the transmitter unit is activated when there is a difference between the averages of ten readings in one minute with the previous average reading. Temperature and humidity were measured over a 12-hour period. The conventional sensor node needed to send 60 packets of data within an hour, which could be repeated data. The use of the smart node algorithm improved current consumption by 93% compared to the commercial node. The integration of the wireless sensor node with the smart algorithm has several advantages, such as the number of packet data sent is lower and of high accuracy, the total power consumed for the node is lower. In addition to the possibility of increasing the number of sensor nodes in the wireless sensor network.
