Nano materials are being used in concrete technology to enhance performance grade sustainably of construction field works like rigid highway pavement. Nano materials like Nano Al2O3 are used as admixture for the cementitious materials to improve the mechanical and durability properties related to the physio-chemical reactions. The overall objective of this research is to evaluate the effects of Nano Al2O3 addition on the abrasion durability response of concrete pavement. These investigations are conducted to study different Nano Al2O3 contents (0.5, 1, 1.5, 2%) by weight of cement on the concrete strength and abrasion resistance by using the manufactured calibrated rotary cutter device for evaluation process and microstructure analysis by Scanning Electronic Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) tests. The compressive strength was tested at 28 days of curing and the results showed that the compressive strength of concrete increases up to 36% at 28 days by addition of 1% nano-alumina as a replacement of cement; Optimal content (1% by weight of cement) is found that appears better abrasion, durability abrasion performance and at the same time, achieves the main requirement of concrete highway pavement (strength and workability).

Electro-Coagulation (EC) method is the most effective electrochemical treatment of the wastewater that contains heavy metals as pollutants such as (lead compounds). It is consumed less energy compared with the other conventional methods. In this work, the Computational Fluid Dynamics (CFD) modeling approach for the simulation of the EC unit was studied. Transport of species, current-voltage distribution, and fluid flow were simulated using the diffusion, Nernst-Planck, and Navier-Stokes equations, respectively. The commercial software (COMSOL 5.4) was used to solve the system of equations that govern this problem. The influence of different parameters such as Hydraulic Retention Time (HRT) (15-45 min), applied voltage (2-10v) rotating speed of electrode (0-150 rpm) on the EC reactor also has been studied. The extracted results from the simulation show how the voltage, current, velocity and concentration of the pollutant and coagulant are distributed in the reactor. Besides, the transient behavior of the lead removal from the water was demonstrated in this work. The obtained results from this study were compared with experimental results. The theoretical results showed a good prediction of lead removal from water by electrocoagulation system and they showed good agreement between predictive and experimental data.

The effect of reed leaves extract (RLE) as an eco-friendly corrosion inhibitor for reinforcing steel in concrete immersed in 3.5% NaCl solution was investigated. The work was carried out using Linear polarization resistance, Potentiodynamic polarization, cyclic polarization, photographic examination, impressed voltage and compressive strength tests. Results obtained from Tafel polarization curves after 180 days immersion showed that corrosion rate was decreased and efficiency was increased with increasing of concentration of RLE inhibitor. The minimum corrosion rate was 2.259 μmpy with maximum efficiency of 76.98% at 0.5% RLE concentration (by cement weight). Also, the photographic study results indicated that inhibited surfaces are more smooth compared to control surface (without inhibitor). Cyclic Voltammetry curves showed that steel samples with RLE inhibitor have low tendency to pitting corrosion compared with control samples. On the otherhand, compressive strength test indicated that addition of RLE inhibitor to concrete mix increased compressive strength by 7.16 % at 0.5% concentration. Impressed voltage test showed that corrosion of reinforced steel bar initiated on the seventh day of experiment for control sample while on the eighteenth day for RLE sample at 0.5% concentration. The results of this study revealed that RLE acts as a good eco-friendly corrosion inhibitor.

This paper conducts an experimental study on the behavior of two-spans continuous reinforced concrete spliced girders strengthened using steel fiber concrete of volume fraction of 1% at splice regions and side near surface mounted carbon fiber reinforced polymer bars of 6 and 10 mm sizes. Five beams with 150 × 250 mm rectangular cross section and 2200 mm total length were cast. The first beam was cast as one unit without joints as a reference while the rest were made from assemblage of three precast segments spliced together using cast in place concrete joints of 170 mm length located at the inflection points. All girders were tested using a single concentrated force at each midspan. The studied parameters were: existence of splices, using of steel fiber concrete at splice region, and strengthening of spliced girders using side near surface mounted carbon fiber reinforced polymer bars. The results showed that existence of splices led to a decrease in the ultimate capacity of the spliced girder of about 33.1% with larger midspan deflections in comparison with the non-spliced girder. But, strengthening of spliced girders using CFRP bars could provide additional load capacity from 69.1% to 98.1% compared with the non-strengthened spliced girder with lower midspan deflections while steel fiber concrete at joints raised the ultimate load of spliced girders by 12.3%. However, the failure mode of the spliced beams were brittle if compared with the ductile failure of the control girder.

On the other hand, the relation developed for power measurement helps to prevent power loss and consumption.

Vanadium redox flow battery (VRFB) becomes a global technology used in stationary applications like grid storage. The characteristics of output voltage during the charge-discharge cycles and the resulted power of VRFB are strongly based on solving a multidisciplinary problem. In this paper, a 2 D steady state numerical model for the operation of a single VRFB has been formulated, validated with good agreement, and tested. The output voltage response of VRFB at different state of charges (SOCs) has been investigated under range of volumetric flow rates and current densities. Next, a comprehensive parametric analysis, sensitivity study, for the major electrode and electrolyte material properties is conducted which can improve confidence in model predictions. The results showed that increasing flow rate can help to minimize concentration polarization, however, pumping power would be dominated. A low flow rate can cause some poor covered regions, but would reduce pumping power. Based on the sensitivity results, only cathode reaction rate, specific surface area, conductivity of porous electrode and electrolyte, and carbon felt porosity are input parameters that dominate the simulation results. It is expected that this proposed model would be applicable to most flow batteries architectures and can be extended to stack flow batteries.

Water wells are considered one of the important sources for drinking and agricultural needs. To improve the quality of water wells, ten samples were taken from water wells, which are located in various places from Kufa city /Najaf. Wells are used for multi purposes: irrigation, drinking, cooking and other household uses. Two methods were adopted to achieve the essential requirement; one is ion exchange, while the other is activated carbon method. Study results show the unsafe of some water wells used for drinking purposes because some ions concentrations have exceeded the allowable limits of sulfate SO4-, chlorides Cl-, and also water hardness. All these parameters exceeded the limits for drinking uses. However, they were within the allowable magnitudes for agricultural uses. Water wells can classify into two classes, one for irrigation water with high salinity valid to irrigate some crops, which withstand a certain percentage of salinity in soils. The second was classified as water with very high salinity, which have used in case of irrigating crops that resist high levels of salinity. Study concluded that the method of activated charcoal was improved the water quality better than method of ion exchange.

Data compression is a special case of communication system which is a basic problem in engineering and computer science. In this work, the new scheme has been introduced for data coding to compress the size. Compression by using one type of Non-linear Data-Structure which is Prefix Binary Tree data compression is essential and beneficial in the diversity of application which is embraced in general into two branches: the storage and transmission.the storage of a file in a compressed form takes fewer bit than in uncompressed form, therefore make the most of storage resources (containing main memory itself), and by transmission means sending the files over a channel with reduced number of bits by compression process. This leads to more efficacious transmission process. The compression process of stored data or that to be transmitted leads to significantly reducing both of the storage and transmission. We use text type as a data in the experiments. The results show the compression rate is reduce the actual size above 50%.

An efficient pretreatment step is essential to ensure maximum and economical recovery of the fermentable sugar from enzymatic hydrolysis of lignocellulosic biomass. Microwave-assisted pretreatment was found to be a good alternative of conventional heating pretreatment of acid or alkali due to its direct heating of sample which reduce the energy consumption. The present study aims to evaluate the effect of using very diluted solvent (acid and alkali) on monomeric sugar yield during microwave-assisted pretreatment of lignocellulosic biomass (sago palm bark wastes). The changes of the surface structure of untreated and pretreated lignocellulosic biomass were detected using SEM analysis. Three solvents were employed at three concentrations (0.01, 0.05 and 0.1 N). The solvents that utilized in the microwave-assisted pretreatment were sulphuric acid (MA), sodium hydroxide (MH) and sodium bicarbonate (MB) and compared with distilled water (MW). Sago palm bark (SPB) was soaked in these solvents as a substrate at 5% w/v and subjected to microwave power at 800 W in a modified household microwave oven for 5 minutes. Immersing feedstock in distilled water and heating using microwave heating released 5.32 mg/g of monomeric sugar. Highest yield of monomeric sugar was found using 0.1N H₂SO₄ which yielded 10.28 mg/g during. Applying the pretreatment using the similar concentrations of NaOH and NaHCO₃ released 9.35 and 4.31 mg/g of monomeric sugar, respectively. Decreasing chemical solvent level from 0.1 to 0.05 and 0.01 N shows a negative influence on sugar yield for MA and MH pretreatment while MB pretreatment displays a positive effect by extracting some useful components such as xylose.

Neural networks have a great place in approximating nonlinear functions, especially those Lebesgue integrable functions that are approximated by FNNs with one hidden layer and sigmoidal functions. Various operators of neural networks have been defined and achieved to get good rates of approximation depending on the modulus of smoothness. Here we define a new neural network operator with a generalized sigmoidal function (SoftMax) to improve the rate of approximation of a Lebesgue integrable function L_p, with p < 1, to be estimated using modulus of smoothness of order k. The importance of choosing SoftMax function as an activation function is its flexible properties and various applications.

Let M be a Γ-monoid and A a unitary right M_Γ-act. We have introduced and studied the notion of full stability on gamma acts. We say that A is fully stable if f(B)⊆ B, for each M_Γ-subact B of A and M_Γ- homomorphism f: B→A. This is equivalent to saying that f(aΓM) ⊆ aΓM for each element a in A. Many properties and characterizations of this class of gamma acts have been considered. In fact we show that full stability of M_Γ-act A is equivalent to the following equivalent conditions (1) For each a∈A, (L_A(R_M(aΓM)))= aΓM. (2) For all a, b ∈ A and R_M(aΓM) ⊆ R_M(bΓM) implies that b ∈ aΓM. (3) For each a ∈ A, there is a Γ-compatible ρ on M such that (L_A(ρ)) = aΓM. (4) [aΓM:bΓM]=[R_M(bΓM): R_M(aΓM)] for all a, b ∈ A where M is a commutative Γ-monoid. (5) Every M_Γ-homomorphism from any essential M_Γ-subact B of A into A satisfies f (B) ⊆ B and Hom_MΓ(B,C) = Hom_MΓ(B,C) = ϴ, for any M_Γ-subacts B, C of A with zero intersection.

In our paper, we make two new extensions for the integral type condition for a set valued mapping in a complete partial metric space (Y, p):

1- $\psi \left(\displaystyle {\int }_{0}^{H(Gx,Gy)}\varphi (t)dt\right)\le \psi \left(\displaystyle {\int }_{0}^{p(x,y)}\varphi (t)dt\right)-\phi \left(\displaystyle {\int }_{0}^{p(x.y)}\varphi (t)dt\right)\forall x,y\in Y$

2- $\psi\displaystyle {\int }_{0}^{H(Gu,Gv)}h(t)dt\le\mu(\text{p}(\rm{u},\rm{v}))\psi\displaystyle {\int }_{0}^{p(u.v)}h(t)dt,\forall u,v\in Y$.

And by using these two conditions we prove that a set valued mapping can have a fixed point in a complete partial metric space. Finally we illustrate each condition by an example as an application for these two theorems.

Many properties and characterizations of this class of R_Γ-modules are considering, and obtain some relatied results, as well as, their relationship with full stability.

The quantitative description of data is very essential for statistics. In standard statistics data are assumed to be numbers, vectors or classical functions. But in applications, real data are frequently not precise numbers or vectors, but often more or less imprecise. All kinds of data which cannot be presented as precise numbers or cannot be precisely classified are called non-precise or fuzzy. The present paper focused on obtaining the maximum likelihood and approximate Bayesian estimators of the parameters and hazard rate function for Lindley distribution when the data are available in fuzzy form. Since there are no exact forms, maximum likelihood estimators have been derived according to the algorithm of Newton- Raphson as an iterative technique and Bayes estimators have been derived based on informative gamma priors relative to squared error and precautionary loss functions according to a numerical approximate Lindley's technique. The obtained estimators have been compared through Monte-Carlo simulation study.

In this work, an optical heterodyne temperature sensor system had been designed using Fiber Bragg Grating (FBG). Two techniques implemented. The first standard design uses dual laser diodes LDs as a laser sources that satisfy the condition of beat frequency range. The second new heterodyne optical system designed to get tunable source from single laser source using FBG, which is used as tunable element. By controlling the ambient temperature of the FBG, the wavelengths and their ranges can be controlled in way that satisfies the condition of beat frequency range. Mach-Zehnder interferometer (MZI) sensing technique had used with FBG element in both reference arm and sensing arm. Then the new modified heterodyne optical system had done by utilizing FBG in both reference arm and sensing arm with single source. A comparison study of results by using Optisystem software shows that, the modification of the second design provides better performance by increasing the wavelength shift and the sensitivity of the modified heterodyne temperature sensor.

The technique of chaotic system is considered one of the applications for high security encryption, where a color images sent is encrypted for the purpose of preserving from hacker futility. The color images which are used to study are in both formats JPG and BMP. This paper deals with the method of the numeric encryption key to encrypt each one of the two formats type images and then decrypt the result images using the same key. The measures where used to study the statistical characteristics of result images are the histogram of images, original signal divided by noise signal rate (SNR), maximum squared errors (MSE) and peak signal to the noise rate (PSNR). It is found that the chaotic key with control parameter (r) in rang (3.4567-- 4) and initial value(x) within rang (0.6716 -- 1) make high mixing. Encryption results for BMP color images are very good and efficiently, because of the decryption process given the same input image and have the same pixels values without any loosed values. The result of encryption technique for the color images in JPG format is given a little and acceptable loss because of resaving process for resaving output images using compress data in jpg format algorithm.

In this work, localized surface plasmon resonance based fiber optic (LSPR-FO) sensor utilizing gold nanoparticles (Au NPs) with different sizes is theoretically constructed and analyzed. Three layers (fiber core, Au NPs, and the Analyte) configuration designed by using the matrix method. Performance parameters such as sensitivity, signal to noise ratio, the figure of merit, and resolution of the sensor are evaluated for each size of Au NPs. As a result, sensitivity and resolution exhibit no change with Au NPs size change while the signal to noise ratio and figure of merit decrease as Au NPs size increase. This work shows that the optimized LSPR-FO sensor may have highly promising applications in chemical sensing.

This paper aims at shedding light on investigating the effect of varying plasma parameters of the magnetron sputtering system, the optical emission spectroscopy was used to reach the aime of the paper ; i.e. intensity of spectral Ar-I and Ar-Π lines, electron temperature (T_e), electron density (n) with applied (300-700) V, and working pressure (0.5 – 3.5) mbar. The glow discharge plasma was produced by using Ar gas and gold as a sputtering target. The obtained results showed that the relationship between the spectral lines intensity and electron temperature is positive: the increase of them lead to an increase in the applied voltage while density of electron decreases as the applied voltage is increase in the range (350 – 550) V. Moreover, the Ar-I and Ar-Π spectral lines and electron density increased while its electron temperature decreased following the rise of the gas pressure. The increscent in emission intensity and electron density started to enhance or reduce from low pressure to medium and then increased nearly exponentially, while for high pressure no significance change was observed.

Triglycine Sulfate (TGS) single crystal were grown using a slow evaporation method utilizing deionized water as a solvent at room temperature in two groups. The first group of crystals was grown in a variable pH medium. The second group consisted of crystals doped by Al ions with a varying concentration ratio. It was found that all the TGS crystals grown belong to the monoclinic system, as confirmed through XRD patterns. The results from UV-Vis analysis showed that the crystals grown in the acidic medium were more transparent with increased transmittance to visible light. In addition, the spectral patterns for the as-grown crystals were studied using the FTIR technique, which showed a slight shift, indicating that all the crystals had a similar crystalline structure. The high transmission in the entire visible region for all crystals indicates potential for use of such crystals in (SHG) devices and applications based on UV tunable lasers.

In present work, the modified chemical bath deposition method (CBD) called successive ionic layer adsorption and reaction effective coast method was used for deposited copper oxide CuO nanostructured thin films. Structural, surface texture and optical characteristics of the deposited films were studied as a function of low annealing temperature (150, 200 and 250) °C. X-ray diffraction studies showed that the as-deposited and annealed films exhibited low crystallinity of polycrystalline nature in the monoclinic phase. It is observed a fixed or very little increment of peaks intensity and the crystallinity of the deposited films with the increase of annealing temperature to 250 °C. The lattice constants were calculated and show good agreement with the standard values. The crystallite size was decreased, whereas the dislocation density and the number of crystallites were increased with the increment of annealing temperature. The average grain diameter was increased and the average surface roughness decreased with the increment of annealing temperature. The optical energy gap for the as-deposited film is 1.87eV and increased to (2.03, 2.06 and 2.09) eV with the increment of annealing temperatures. The Urbach tails energy width decreased from 0.91 eV to (0.73, 0.54 and 0.46) eV for as-deposited and annealed films at low temperatures (150, 200 and 250) °C respectively. The low annealing temperatures was used because the deposition process was performs at low temperatures below 100 °C, therefore_it can be concluded that the low annealing temperatures used in this work are not suitable temperatures for the growth of CuO films and it can be above 300 °C to enhance the film crystallinity and formation of CuO phase.
