The efficient removal of dissolved organic compounds (DOC) from wastewater has become a major environmental concern because of its high toxicity even at low concentrations. Therefore, a technique was needed to reduce these pollutants. Ion exchange technology (IE) was used with Amberlite^TM IR120 Na, Amberlite^TM IR96RF, and Amberlite^TM IR402, firstly by using anion and mixed bed system, where the following variables are investigated for the process of adsorption: The height of the bed in column (8,10 and 14 cm), different concentrations of (DOC) content at constant flow rate. The use of an ion exchanger unit (continuous system) with three columns (cation, anion, and mixed bed) was studied.

This research will cover different aspects of estimating process of construction work in a desert area. The inherent difficulties which accompany the cost estimating of the construction works in desert environment in a developing country, will stem from the limited information available, resources scarcity, low level of skilled workers, the prevailing severe weather conditions and many others, which definitely don't provide a fair, reliable and accurate estimation. This study tries to present unit price to estimate the cost in preliminary phase of a project.  Estimations are supported by developing mathematical equations based on the historical data of maintenance, new construction of managerial and school projects.

This paper presents a point multiplication processor over the binary field GF (2²³³) with internal registers integrated within the point-addition architecture to enhance the Performance Index (PI) of scalar multiplication. The proposed design uses one of two types of finite field multipliers, either the Montgomery multiplier or the interleaved multiplier supported by the additional layer of internal registers. Lopez Dahab coordinates are used for the computation of point multiplication on Koblitz Curve (K-233bit). In contrast, the metric used for comparison of the implementations of the design on different types of FPGA platforms is the Performance Index.

The first approach attains a performance index

In this paper, researchers have employed various methods and experimental ways to investigate the behavior of the soil-anchors system under the influence of varying load conditions. Also to focus on studying this system with improving the soil under loading with the anchor as a system. Therefore, the effect of soil geogrid improves the vertical anchor plates performance, and the test results show that the size, location, height, position, water content of the improved mass, and the variation of pullout load angle (0,25.45.60,90) degrees affect the resistance of the vertical anchor plate. But the improving the soil-anchors system with compaction the soil surrounding the anchor, adding the cement to soil, and improving wit

This study provides a comprehensive overview of the characteristics of nano-silica and nano-clay and their impact on preventing dissolved salt of gypseous soil containing high gypsum of 80.4% during the leaching process. The investigation evaluates the impact of several proportions (1, 3, and 5%) on the behavior of gypseous soil. The leaching test was performed using a physical model with a steel box (70×70×70) cm. During this leaching stress, settlement due to the leaching process, and total dissolved salts were measured. Also, after the end of the test, the remaining concentration of gypsum salt in the soil was measured. Nanomaterials exert a beneficial influence in reducing soil leaching settlement, especially for s

In this paper, an experimental analysis of conventional air-cooled and microchannel condensers in automotive vapor compression refrigeration cycle concerning heat transfer coefficient and energy using R134a as a refrigerant was presented. The performance of two condensers and cycles tested regarding ambient temperature which it was varied from 40^oC to 65^oC, while the indoor temperature and load have been set to be 23^oC and 2200 W respectively. Results showed that the microchannel condenser has 224 % and 77 % higher refrigerant side and air side heat transfer coefficient respectively than the coefficients of the conventional condenser. Thus, the COP, in case of using the microchannel

Rate of penetration plays a vital role in field development process because the drilling operation is expensive and include the cost of equipment and materials used during the penetration of rock and efforts of the crew in order to complete the well without major problems. It’s important to finish the well as soon as possible to reduce the expenditures. So, knowing the rate of penetration in the area that is going to be drilled will help in speculation of the cost and that will lead to optimize drilling outgoings. In this research, an intelligent model was built using artificial intelligence to achieve this goal.  The model was built using adaptive neuro fuzzy inference system to predict the rate of penetration in

The recent development in communication technologies between individuals allows for the establishment of more informal collaborative map data projects which are called volunteered geographic information (VGI). These projects, such as OpenStreetMap (OSM) project, seek to create free alternative maps which let users add or input new materials to the data of others. The information of different VGI data sources is often not compliant to any standard and each organization is producing a dataset at various level of richness. In this research the assessment of semantic data quality provided by web sources, e.g. OSM will depend on a comparison with the information from standard sources. This will include the validity of semanti

A robust video-bitrate adaptive scheme at client-aspect plays a significant role in keeping a good quality of video streaming technology experience. Video quality affects the amount of time the video has turned off playing due to the unfilled buffer state. Therefore to maintain a video streaming continuously with smooth bandwidth fluctuation, a video buffer structure based on adapting the video bitrate is considered in this work. Initially, the video buffer structure is formulated as an optimal control-theoretic problem that combines both video bitrate and video buffer feedback signals. While protecting the video buffer occupancy from exceeding the limited operating level can provide continuous video str

in this study a proposed design for reinforced conerete barriers in industrial units is presented. The barriers are deemed to mitigate the hazards of internal explosions to protect the surroundings. The Technical Manual (TM5-1300) for fortified struetures recommends the use of lacing reinforcement barrier walls when the plastic rotation exceeds a specified limit. Such reinforcement is essential in shear design but it needs special skill and additional cost. To avoid using lacing reinforcement, walls of grillage system is proposed in this study to reduce the plastic rotation of pancls. The panels are designed to respond plastically, while the grillage members respond clastieally. This is advantageous from reeruiting point of view since on

Internet paths sharing the same congested link can be identified using several shared congestion detection techniques. The new detection technique which is proposed in this paper depends on the previous novel technique (delay correlation with wavelet denoising (DCW) with new denoising method called Discrete Multiwavelet Transform (DMWT) as signal denoising to separate between queuing delay caused by network congestion and delay caused by various other delay variations. The new detection technique provides faster convergence (3 to 5 seconds less than previous novel technique) while using fewer probe packets approximately half numbers than the previous novel technique, so it will reduce the overload on the network caused by probe packets.

The effect of the initial pressure upon the laminar flame speed, for a methane-air
mixtures, has been detected paractically, for a wide range of equivalence ratio.
In this work, a measurement system is designed in order to measure the laminar flame
speed using a constant volume method with a thermocouples technique. The laminar
burning velocity is measured, by using the density ratio method.
The comparison of the present work results and the previous ones show good
agreement between them. This indicates that the measurements and the calculations
employed in the present work are successful and precise.

    Soft clays are generally sediments deposited by rivers, seas, or lakes. These soils are fine-grained plastic soils with appreciable clay content and are characterized by high compressibility and low shear strength. To deal with soft soil problems there is more than one method that can be used such as soil replacement, preloading, stone column, sand drains, lime stabilization and Prefabricated Vertical Drains, PVDs. A numerical modeling of PVD with vacuum pressure was analyzed to investigate the effect of this technique on the consolidation behavior of fully and different depths of partially saturated soft soils.  Laboratory experiments were also conducted by using a specially-designed large consol

Many problems are facing the installation of piles group in laboratory testing and the errors in results of load and settlement are measured experimentally may be happened due to select inadequate method of installation of piles group. There are three main methods of installation in-flight, pre-jacking and hammering methods. In order to find the correction factor between these methods the laboratory model tests were conducted on small-scale models. The parameters studied were the methods of installation (in-flight, pre-jacking and hammering method), the number of piles and in sandy soil in loose state. The results of experimental work show that the increase in the number of piles value led to increase in load carrying ca

This paper presents hydraulic flow units and flow zone indicator for predicting permeability of rock mass from core for Nahr-Umr reservoir/ Subba field. The Permeability measurement is better found in the laboratory work on the cored rock that taken from the formation. Nahr-Umr Formation is the main lower cretaceous sandstone reservoir in southern of Iraq. This formation is made up mainly of sandstone. Nahr-Umr formation was deposited on a gradually rising basin floor. The digenesis of Nahr-Umr sediments is very important du

Population growth and urban development have posed challenges for wastewater treatment plants (WWTPs) locations in large cities such as Baghdad since they fail to meet sustainability criteria due to outdated planning and the lack of an approved strategy to determine the appropriate location for a WWTP in it. This study aims to develop a decision-making strategy for sustainable sites for WWTPs by using the Fuzzy Analytic Hierarchy Process (FAHP) and applying the strategy to evaluate the locations of the major WWTPs in Baghdad. Nine factors affecting decision-making regarding WWTP locations were categorized into three groups based on environmental, economic, and social sustainability requirements. A questionnaire method wa

Productivity estimating of ready mixed concrete batch plant is an essential tool for the successful completion of the construction process. It is defined as the output of the system per unit of time. Usually, the actual productivity values of construction equipment in the site are not consistent with the nominal ones. Therefore, it is necessary to make a comprehensive evaluation of the nominal productivity of equipment concerning the effected factors and then re-evaluate them according to the actual values.

In this paper, the forecasting system was employed is an Artificial Intelligence technique (AI). It is represented by Artificial Neural Network (ANN) to establish the predicted model to estimate wet ready mixe

A flight simulation programme has been developed on a personal computer using Microsoft
FORTRAN to simulate flight trajectories of a light aircraft by using Six-Degree-of-Freedom
equation of motion. The simulation has been made realistic through pre-programmed the input to
the control surfaces, atmospheric gust during the flight mode. The programme plays an important
role in the evaluation and validation of the aircraft design process. A light aircraft (Cessna 182T)
has been tested through free flight, gliding flight, flight with gust. The results show good trend and
show that the programme could be dependent as a realistic flight test programme.

This study investigates the results of electrocoagulation (EC) using aluminum (Al) electrodes as anode and stainless steel (grade 316) as a cathode for removing silica, calcium, and magnesium ions from simulated cooling tower blowdown waters. The simulated water contains (50 mg/l silica, 508 mg/l calcium, and 292 mg/l magnesium). The influence of different experimental parameters, such as current density (0.5, 1, and 2 mA/cm²), initial pH(5,7, and 10), the temperature of the simulated solution(25⁰C and 35 ⁰C), and electrolysis time was studied. The highest removal efficiency of 80.183%, 99.21%, and 98.06% for calcium, silica, and magnesium ions, respectively, were obtained at a current de

A roundabout is a highway engineering concept meant to calm traffic, increase safety, reduce stop-and-go travel, reduce accidents and congestion, and decrease traffic delays. It is circular and facilitates one-way traffic flow around a central point. The first part of this study evaluated the principles and methods used to compare the capacity methods of roundabouts with different traffic conditions and geometric configurations. These methods include gap acceptance, empirical, and simulation software methods. Previous studies mentioned in this research used various methods and other new models developed by several researchers. However, this paper's main aim is to compare different roundabout capacity models for acceptabl

Grayscale images are extensively used due to their simplicity and cheapness in storage and transmission compared to color one of RGB base. It can also be considered a solution for color-blind people to ensure a better view of things and reading. However, unfortunately, it is still quite overburdened with redundancy(s) in which the data compression exploits them efficiently depending on the type and way of redundancy removal. This work introduces a hybrid compression system to compress grayscale images using the adaptive pixel-based technique (PBT) of optimized modeling base, with incorporated Minimize Matrix Size Algorithm (MMSA) of three digits values (C321) to encode the residual compactly along the need to overhead in

Clustering high-dimensional data remains challenging because traditional k-means is sensitive to noise, outliers, and high dimensionality, often leading to unstable performance. The research presents a robust clustering system which combines the Fully Corrective Frank-Wolfe (FCFW) algorithm with k-means objective that uses Frobenius norm regularization. The addition of Frobenius norm regularization in the model produces more stable clusters while preventing overfitting and promoting cluster compactness. The proposed method uses probabilistic cluster assignments to enable each data point to join multiple clusters at different membership levels, thus supporting clusters with overlapping boundaries. The Kr

Taziz Al-Taziz irrigation pumping station, within Al-Muthanna Governorate, Iraq, was studied, aiming at investigating the performance of its stilling basin in reducing the energy of the water out of the discharge pipes outlet. The study relied on the results of the physical model of the basic design of the stilling basin and the use of ANSYS Fluent 21.0 software to simulate both the basic design and the as-built stilling basin.  The physical model was constructed and studied by the Center for Studies and Engineering Designs of the Iraqi Ministry of Water Resources.  Simulations showed the variation in velocity within the basic design of Taziz Al-Taziz pumping station to be 3.98 m/s to 0.209 m/s in the basin, with an av

This research describes a new method for estimating tramadol hydrochloride in pharmaceutical formulations using Molecularly Imprinted Solid-Phase Extraction (MISPE) as a sample extraction technique. Acrylamide was used as the functional monomer, trimethylolpropane Trimethacrylate as the cross-linker, and tramadol hydrochloride as the template molecule to make Molecularly Imprinted Polymer (MIP).

Software Defined Networking (SDN) allows for more flexible network administration than traditional architectures. Software-defined networks (SDNs) efficiently manage data flows and optimize network resources. However, heterogeneity influences the quality of the services. (QoS) needs and network resource demands. They behave differently when traveling to their last point. Currently, numerous data center networks (DCNs) struggle with the unfair use of several network resources by big packets (Elephant flowing) arriving during any instant affecting specific flows (mice flow). Elephant Flows (EF) account for just a small percentage of the entire traffic. Nevertheless, they are considered Long-lasting (LLF) and often burn net

A road network uses rigid pavement for various purposes, still, it can face several challenges, including cracking from temperature changes, shrinkage, load stress application, brittleness, and flexural and tensile weakness. The thickness of rigid pavement significantly influences its performance and durability. A thicker slab distributes weight more effectively on the subgrade; however, greater thickness significantly raises construction costs, requires more resources, and negatively impacts the natural environment. The purpose of this study is to find out how adding a 1% volume fraction of steel and glass fiber in single and hybrid shapes changes the mechanical properties of concrete and pavement thickness. The compres

Several techniques are used to improve the channels' heat transfer coefficient and Nusselt number. One of the methods used for these improvements is porous media (PM). This research deals with an experimental study of heat transfer by forced convection inside a square-shaped channel (0.12 x 0.12 m²) with a length of (0.5 m) and a hydraulic diameter of (0.12 m). The heat flux (4791.7 W/m²) is exposed below the test section, and other walls are thermally insulated. The air was used as the working fluid for the Reynolds number range (2689.6 to 5806.3). The channel was partially filled with the PM (glass spheres with 5mm diameter) by taking three different heights layers (20, 40, and 60 mm) and knowing
