Research ArticleOpen accessEvery word in the titleFull Capacity Image Steganography Using Seven-Segment Display Pattern as Secret KeyMohammed A. Fadhil Al-Husainy, Hamza Abbass A. Al-SewadiDue to the vast interchange of images over the internet, exchanging secret message hidden in these images would be encouraged and the technique is referred to as image steganography. Hiding the secret data into the least significant bits of the images pixels is a common practice. However, the choice of the hidden key and the efficiency of utilizing all pixels … …Journal of Computer Science, Vol. 14, Issue 6 · 14 Apr 2018 · 7,851 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleThe Efficiency of Seven-Variable Box-Behnken Experimental Design with Varying Center Runs on Full and Reduced Model TypesMary Paschal Iwundu, Joan CosmosResponse Surface Methodology is widely used in the optimization of industrial processes and products that depend on several experimental variables. One of the most tested and efficient second-order Response Surface Methodology designs is the Box-Behnken Design. This research explores the efficiency of a seven-variable Box-Behnken design with varying center runs, on full and reduced quadratic models. Backward Elimination and Forward … …Journal of Mathematics and Statistics, Vol. 18, Issue 1 · 8 Dec 2022 · 7,089 accessesView PDFCite
Case ReportOpen accessEvery word in the titleFree-Living Amoebae and Central Nervous System Infection: Report of Seven CasesAlcalá Martínez Enrique, Gaona Flores Verónica A., Paz Ayar Nibardo, González Guerra EduardoThe Free-Living Amoeba (FLA) is an opportunistic protozoan with a cosmopolitan distribution that can cause Central Nervous System (CNS) infection. It develops in relatively stagnant waters such as swimming pools, lagoons and ponds but only species belonging to the genera Hartmannella, Naegleria, Acanthamoeba and Balamuthia have been found in humans. The resulting pathology is highly lethal due to the lack … …American Journal of Infectious Diseases, Vol. 15, Issue 4 · 14 Dec 2019 · 7,058 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEXTENDED MASS RELATION FOR SEVEN FUNDAMENTAL MASSES AND NEW EVIDENCE OF LARGE NUMBERS HYPOTHESISCurtis J. Forsythe, Dimitar T. ValevA previously derived mass relation has been extended to seven equidistant fundamental masses covering an extremely large mass range from ~10-69 to ~1053 kg. Six of these masses are successfully identified as mass of the observable universe, Eddington mass limit of the most massive stars, mass of hypothetical quantum “Gravity Atom” whose gravitational potential is equal to electrostatic potential e2/S, … …Physics International, Vol. 5, Issue 2 · 16 Jul 2014 · 8,271 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Monte Carlo Study of Seven Homogeneity of Variance TestsHoward B. Lee, Gary S. Katz, Alberto F.
