If 𝒜 ≪j Dj(𝒲), where Dj(𝒲) is the generalised Jacobson radical of 𝒲, then a sub-module 𝒜 of a module 𝒲 is said to be Dj-small. If W=A+Band AnB≪jDj(A), 𝒜 is Dj- ’supplement of ℬ in 𝒲. 𝒲 is said to be Dj- ’supplemented if every sub-module of 𝒲 has Dj- ’supplement in 𝒲. If for each 𝒜 a sub-module of 𝒲, there exists a sub-module ℬ such that W=A+Band AnB≪jDj(W), then 𝒲 is called Dj-weakly ’supplemented module.

Due to the worldwide expansion of the internet, the consumption and transmission of multimedia materials have risen significantly. This growth in demand necessitated a corresponding increase in data security measures. This work investigates encryption technology and proposes a novel color picture encryption and decryption approach based on the “SEE transform” developed by Sadiq, Emad, and Eman. We used the SEE transform to encrypt the original image, and the corresponding inverse SEE transform for decryption. The SEE transform has been performed to enhance the security of the encryption method. After using the SEE transform, we show that the suggested method considerably improves security measures and immunity to attacks, as demonstrated by comprehensive experiments and statistical analysis.
The Extinction Time Probability Distribution: Some Empirical ExperimentsAl-Azzawi, Hussein F.

The aim is to calculate the parametric and nonparametric probability distribution of the time until extinction for two stochastic predator-prey models namely the Rosenzweig-Macarthur and May models. We assume a climate variability parameter r to change in value each year. The amplitude of the variable r is a normally distributed random variable truncated to the closed interval [r1, r2]. Two such intervals are used with two different values of variance for the normal distribution. Simulation is used to generate the data for each case and the data is analyzed to obtain the best fit probability distribution.

The 𝛶 subclasses S*(τ, λ) and C*(τ, λ), as well as the class of analytic and univalent functions of the form h(w)=w−∑i=2∞|ei|wi, were studied. Sharp coefficients, distortion, as well as a function expression formula in S*(τ, λ) are determined, as well as expression formulae for functions in C*(τ, λ). In addition, convex linear combination over arithmetic average, the classes S*(τ, λ) and C*(τ, λ) are proved to be closed.

In this paper, a concentrating photovoltaic system (CPV) by using a compound parabolic concentrator and a monocrystalline solar module has been designed and studied theoretically under a concentration ratio of 3.16x. The performance the system is studied over the course of the day from 8:00 AM to 16:00 PM for 12 months under Iraq-Baghdad conditions. Current in a short circuit (Isc), voltage in an open circuit (Voc) as well as maximum power (Pm) are calculated with and without a concentrator under constant solar module temperature (25°C). The results indicated that the optimum value of output power can be obtained on June 21, which is about 246.9W for CPV. In the second part, the effect of solar cell temperature within a range of 25 °C−115 °C on its performance has been studied for the optimum day of the year, June 21st. The output power of the device may be viewed in CPV is 246.9 W in comparison to the flat PV module, which gives 83.44W under solar cell temperature of 25°C and decreases to 125.3W and 40W under cell temperature of 115°C for the CPV and flat module, respectively.

Adomian decomposition Tarig transform technique (ADTTM) is a new variant of the A domian decomposition method for solving various models of partial differential equations. The Adomian decomposition method and the Tarig transform are combined in the ADTTM. The research makes extensive use of concrete instances. For many linear and nonlinear models, the new modification provides a useful tool.

As an alternative to antibiotics, nanoparticles are increasingly being employed to target bacteria. Nanotechnology has the potential to revolutionize the treatment of bacterial infections. Biosynthesis is becoming increasingly popular as a cutting-edge method for producing functionally diverse Nanoparticles with enormous therapeutic potential. Various biological resources have already proven their ability to manufacture Nano-particles with unique properties. They have a diverse and distinct pool of possibly therapeutic secondary metabolites that can reduce metallic ions to Nano-particles. Selenium dioxide Nano-particles were made from Cinnamomum cassia extract (NPs). The created Selenium dioxides were examined using a variety of techniques, including XRD, UV-Vis, and TEM. Two bacteria were used to investigate the anti-bacterial effect.
