  • Effective Detection of Copy Move Forgery Using Surf
    R A Rakhi, Aldin Justin Sundararaj, R. Catherine Joy, and J. Jenkin Winston

    IEEE
    Copy move forgery is a technique for altering digital images by copying and pasting contents from the original image into different parts of the same image. It is of great importance to detect tampering as the credibility of digital images are being lost. Keypoint based methods proved to be efficient in localizingforgery. The proposed method uses SURF for feature extractionand improved forgery localization method for efficiently localizing forgery. Finally, comparison with the existing keypoint based methods to prove the efficiency of forgery localization in digital images. The tampered image is displayed as binary image for better understanding. The proposed methods efficiently localize forgery even if the tampered region is rescaled, rotated or blurred. The performance is validated by TPR, FPR and F1 score and comparing the same with the existing methods.

    SAGE Publications
    A high altitude test facility was developed for the experimental studies on nozzles for various levels of vacuum. The current study is focused on the performance of the nozzle under various altitude condition and to characterized the high altitude test facility. A supersonic nozzle designed for Mach 2.5 is used for the study. Compressed air is taped from the high pressure plenum having a pressure of 20 bar and is regulated and expanded through the nozzle. The inlet pressures for the study is varied from 4.5 to 10 bar. The nozzle is within the enclosure which is evacuated to 0.7–0.02 bar. Schlieren is used to view the flow condition at the end of the nozzle. A nozzle for 2.5 Mach is designed and tested in HAT facility. The nozzle design is validated with the CFD for various NPR. The high altitude test facility is characterized for various NPR and is found to be optimum flow at 14 NPR for 33 s at an inlet pressure of 4.5.

  • Effect of blast pressure on discrete models using a shock tube
    Aldin Justin Sundararaj, Divya Jose, Alfred Sunny, Sharon Teres John, Nitin Kumar, and Gopalsamy

    IEEE
    There has been a spike in the number of terrorist attacks in the past few years and this has shown the need to study the effect of blast loads on buildings and to be taken into consideration in the design process. This threat shows the need for understanding blast mitigation techniques with materials primarily in the construction of buildings. The eruption of high energy materials produces blast waves. This kind of eruption causes tremendous losses and irreparable damages to both man and man-made structures. The effect of the blast wave is most atrocious closer at the middle or at the point of constructive interference. Shock tubes are used to mimic blast waves. For the purpose of studying the science behind the effects of blast pressure on buildings, experiments were done in the shock tube on discrete configurations are done at various pressures. Various methods are used to vary the strength of shock wave is for example by changing the driver gases or by changing the diaphragm thickness. Discrete models selected are suitably scaled cylinder, cone and cubical blocks with different materials such as Wood, Nylon and Mild steel. Pressures are measured by using PCB Piezo electronic transducers with suitable PCB Piezo electronic signal conditioner and NI data acquisition system. The present work proves that cone was a better option in reducing the impact pressure of shock on the body.

  • Rupture dynamics of shock-tube diaphragm
    J Livil Lyle, K R Guna, Pradeep Kumar, and Aldin Justin Sundararaj

    IEEE
    Diaphragm rupture process in a shock tube was studied through transient simulations. With the help of ANSYS Explicit Dynamics, the rupture process occurring in a shock-tube was simulated. Diaphragms of several thicknesses and scores were analysed. It was possible to predict the pressure difference at which rupture would take place which would help in bring down the cost and time required to setup and carry out experiments in a shock-tube. Experiments has been carried out in a shock tube to validate the simulations results and compared with simulation data.
