To protect digital audio transmissions from unauthorized access and modification, this paper proposes a voice encryption scheme based on chaotic systems. The proposed approach combines multiple chaotic maps into a cryptographic scheme that is applied at the byte level. The input sound is first divided into four equal-length parts. The Rossler system, Lorenz system, Henon map, and Baker map are chaotic systems used to encode each fragment. Four segments are combined, and subsequently, a logistic map is applied to the encoded audio to introduce a flipping step, ensuring a strong spread and confusion throughout the entire signal. During the decoding phase, XOR processes and switching are systematically reversed using saved

The accuracy in oil reserve estimation is very important, as decisions should be made based on this value. The present paper will deal with estimating oil reserves by using deterministic and probabilistic approaches. The case study is the Mishrif formation of the Buzrgan oil field that located in Missan Governorate, southern Iraq. The deterministic approach is represented by the material balance equation, while the probabilistic approach is represented by Monte Carlo simulation. The data used in the material balance equation are production, PVT, and pressure data, along with needing to calculate bulk volume and porosity, while the Monte Carlo simulation needs volumetric equation parameters, which are porosity, fluid satu

This paper investigates the performance evaluation of two state feedback controllers, Pole Placement (PP) and Linear Quadratic Regulator (LQR). The two controllers are designed for a Mass-Spring-Damper (MSD) system found in numerous applications to stabilize the MSD system performance and minimize the position tracking error of the system output. The state space model of the MSD system is first developed. Then, two meta-heuristic optimizations, Simulated Annealing (SA) optimization and Ant Colony (AC) optimization are utilized to optimize feedback gains matrix K of the PP and the weighting matrices Q and R of the LQR to make the MSD system reach stabilization and reduce the oscillation of the response. The Matlab softwar

This study aimed to assess the possible association of oxytocin (OXT) gene with reproductive traits in two groups of Awassi ewes that differ in their reproductive potentials. Sheep were genotyped using PCR—single-stranded conformation polymorphism approach. Three genotypes were detected in exon 2, CC, CA, and AA, and a novel SNP was identified with a missense effect on oxytocin (c.188C > A → p.Arg55Leu). A significant (p < 0.01) association of p.Arg55Leu with the twinning rate was found as ewes with AA and CA genotypes exhibited, respectively a lower twinning ratio than those with the wild-type CC genotype. The deleterious impact of p.Arg55Leu was demonstrated by all in silico tools that were utilized to assess the effect of this varian

The gypseous soil may be one of the problems that face the engineers especially when it used as a foundation for hydraulic structures, roads, and other structures. Gypseous soil is strong soil and has good properties when it is dry, but the problem arises when building hydraulic installations or heavy buildings on this soil after wetting the water to the soil by raising the water table level from any source or from rainfall which leads to dissolve the gypsum content.

Cement-stabilized soil has been successfully used as a facing or lining for earth channel, highway embankments and drainage ditches to reduce the risk of erosion and collapsibility of soil. This study is deliberate the treatment of gypseous soil by u
