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)

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)
Digital images have been spread all over the world. With rapidly development and ease of use of digital image editing tools like Photoshop TM and paint TM, it is important to authenticate or detect the forged regions in any suspicious digital image. In this paper, new and robust method for authenticating and identifying the forged regions in the scanned(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)
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 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)
