    Cosmological evolution of pilgrim dark energy
    (Astrophys Space Sci, 2014) Muhammad Zubair; Muhammad Sharif
    We study pilgrim dark energy model by taking IR cut-offs as particle and event horizons as well as conformal age of the universe. We derive evolution equations for fractional energy density and equation of state parameters for pilgrim dark energy. The phantom cosmic evolution is established in these scenarios which is well supported by the cosmological parameters such as deceleration parameter, statefinder parameters and phase space of ωϑ and ω ϑ . We conclude that the consistent value of parameter μ is μ<0 in accordance with the current Planck and WMAP9 results.

    Digital image encryption
    (University of Management and Technology, 2012) Abdul Moiz Atif; Muhammad Usman Bashir; Muhammad Zubair
    With the advancement of technology, the security of Digital Image is an important issue which is receiving considerable attention in the recent past. In the past few years, several encryption algorithms have been proposed as means to protect digital images against cryptographic attacks. The encryption process transforms the 2-D pixel array into a statistically uncorrelated data set. In this project, a number theory and image based encryption scheme is proposed for the security of data. This technique calculates the sum of matrix of Image and the number of elements in an array. By using these two things we generate a random number which is used for decryption.
