This paper presents three laboratory experiments, which have been carried out using the Molybdenum-99 (Mo(99)) radiotracer to measure the residence time distribution (RTD), the mixing time and the flow rate in a water flow rig. The results of the RTD measurement experiment are preprocessed using the MATLAB software for background correction, radioactive(More)
This paper presents two innovative techniques developed and implemented for the automation of the landmine detection in a data scanned by the laser Doppler vibrometer (LDV) based acoustic to seismic (A/S) landmine detection system. These techniques are based on the intensity component of the color landmine images or on grayscale versions of these images.(More)
This paper introduces a cepstral approach for the detection of landmines from acoustic images. This approach is based on transforming the 2D landmine images to 1D signals using a spiral scan to make object pixels as close as possible to each other after the scan. The Mel-frequency cepstral coefficients (MFCCs) and polynomial shape coefficients are extracted(More)
This paper presents a proposed approach for Residence Time Distribution (RTD) signal identification. The RTD signals were obtained from measurements carried out using radiotracer technique. In this approach, firstly signal processing is performed for background correction, radioactive decay correction, starting point correction, filtering and signal(More)
One of the important applications of radioisotope in industry is the residence time distribution (RTD) measurement. RTD can be used for optimizing the design of the industrial system at the design stage and determination of the system malfunctions. The RTD signal may be subject to different sorts of noise; this leads to errors in the RTD calculations and(More)
Radiotracers can be used in several industrial applications by injecting the radiotracer into the industrial system and monitoring the radiation using radiation detectors for obtaining signals. These signals are analyzed to obtain indications about what is happening within the system or to determine the problems that may be present in the system. For(More)
There are many different data hiding techniques, the Least Significant Bit (LSB) based steganography algorithm is considered as one of the most popular algorithms in the spatial domain. In this paper, the proposed algorithm embeds data in each component of color image, where the signature of the transmitter and the length of the secret text are hidden in(More)
Gamma radiography plays an important role in checking the quality of welded components in many industries. Determination of the region of interest (ROI) which contains only the welding area from the whole radiography image is important process for elimination of irrelevant information, leaving only the area of interest in the image. This paper presents(More)
This paper concerns the development of a practical distributed on-line neurocontrollers for temperature processes using microcontrollers. The suggested controllers are composed of a network of microcontrollers that are coordinated by a supervisor microcontroller interfaced with the user via LCD and remote control system. This distributed control system(More)
In this paper a new identification technique for buried landmine objects is presented. Most of the existing supervised identification methods are based on traditional statistics, which can provide ideal results when sample size is tending to infinity. However, only finite samples can be acquired in practice. In this paper, a proposed learning method,(More)
