Iraq is rich in renewable energy resources while suffering from a severe shortage of electrical power supplying hours, accordingly the current study aims at design a ground source heat pump system (two-ton compression air conditioning systems) utilizing from shallow subterranean energy in order to rationalization electricity consumption. The results refer to huge contribution of shallow geothermal energy source in rationalization in electric power consumption. The results show a doubling in coefficient of performance and reduction in active electric power to more than the half of its original value.

Bayesian analysis for the shape parameter of Exponentiated Rayleigh distribution or (Burr type x) has been considered in this paper, under two priors distributions [Inverted Levy and Quasi] using doubly type II censored data, with two loss functions [Weighted and Precautionary], we conducted a simulation study that evaluate the effectiveness of four estimators by six presumption experiments for varied values of distribution parameters and three sample sizes using mean squared error [MSE]. In general the best estimator of the shape parameter ???? of the (ERD) using Doubly type II censored data is under Inverted Levy prior under Precautionary loss function in all sample sizes

The effect of weathering on physical properties of pure Poly methyl Methacrylate (PMMA) film and PMMA/ Safranin (S) films for Greenhouse applications has been studied. The solution casting method was used to prepare pure PMMA and PMMA/S films with dye solution (18ml), The concentration of Safranin solution was (1×10-4 mole/liter).
Weathering process will be done for these samples at different exposure sun light times (76, 152 and 228) h. Weathering affected on maximum absorption wavelength of Safranin to shift to lower wavelength (520nm) and decrease the absorbance. Also, the optical energy gap will decrease for pure PMMA from (5eV) to (4.8eV) and PMMA/S (18ml) from (5.02eV) to (4.82eV). FTIR results showed that there is no chemical interaction occurs between Safranin and PMMA Polymer, only physical interaction will be occurred. After weathering, the peaks in FTIR spectra shifted slightly and transmitted decreases with increasing the weathering time. These will confidently photostability of these films under weathering conditions and possibility to use them in greenhouse application. It can be concluded that the PMMA /S (18ml) film is better in green house applications in terms of absorption, energy gap and Sun light transmittance, where it is the highest possible transmitted from (10 A.M.) to (3 P.M.).

Image encryption is an essential area of visual cryptography that helps protect images when they are shared over the internet. There are many cryptography algorithms applied for many years in encrypting images. In recent years, techniques from chaotic systems have been combined with DNA coding to help encrypt images and protect them from unauthorized use. In this study, we proposed a new method for image encryption based on a new four-dimensional chaotic system and DNA encoding. The proposed method consists of two stages: the pixel positions are scrambled depending on which chaotic sequences are generated from the new chaotic system; and then, an XOR operation is performed on the image scrambled by using the DNA encoding sequence to get the final encryption image. Analyses such as entropy, NPCR, UACI, and key space are used to evaluate the algorithm's performance. The algorithm attains average entropy of 7.99, which is close to the ideal value of 8 with NPCR and UACI of 99.64 and 33.02, respectively. In addition, the key space is 2627. The simulation results show that the proposed method offers high security, good encryption, and is resistant to many types of attacks

In this paper, a Bayesian analysis is made to estimate the Reliability of two stress-strength model systems. First: the reliability of one component strengths X under stress Y. Second: reliability of one component strength under two stresses. Where X and Y are independent Generalized Exponential-poison random variables with (α, λ, θ) and (β, λ, θ), parameters respectively. The analysis is concerned based on complete data samples using gamma prior under eight different loss functions (Quadratic, Squared error, Weighted, Linear exponential, precautionary, De Groot, Entropy, and non-Linear exponential). The estimators are compared by Mean squared error criteria due to a simulation study and find that the best performance of the estimators found in order as (Quadratic, Weighted, Linear exponential and non-Linear exponential.
