Also in this paper the comparison between the LFTM and the Bio-inspired Trust and Reputation Model for Wireless Sensor Network

This study was conducted to estimate the suction head at the wetting front T in the Green and Ampt infiltration equation using uniformly packed soil columns of three different - textured soils. Four different approaches were used for this estimation. Cumulative depths of infiltration I along with the visual wet front advance Z was recorded with time t. Soil water content profiles were also obtained by which the sharpness of the wet front was tested using an empirical model adopted from van Genuchten (1980) model for soil moisture-suction head relation. The Green and Ampt equation did fit the infiltration data very well with significant correlation of its parameter K with the physical measure of saturated hydraulic conductivity K. Four di

Wireless Multimedia Sensor Networks (WMSNs) are networks of wirelessly interconnected sensor nodes equipped with multimedia devices, such as cameras and microphones. Thus a WMSN will have the capability to transmit multimedia data, such as video and audio streams, still images, and scalar data from the environment. Most applications of WMSNs require the delivery of multimedia information with a certain level of Quality of Service (QoS). This is a challenging task because multimedia applications typically produce huge volumes of data requiring high transmission rates and extensive processing; the high data transmission rate of WMSNs usually leads to congestion, which in turn reduces the Quality of Service (QoS) of multimedia appli

Technology is an important factor for achieving architecture as an impact and vulnerability. It represents one of the significant elements in creating the intellectual framework, as well as having its own intellectual breakdown, while values constitute the most important and obviously factor of the community's intellectual. Research aims was determined accordingly by: investigating the role and impact of values and their relationship to technology in architecture.

In this context, the research investigated values and technology in architecture, through discussing their aspects and dimensions in architecture. In the context of values, the research discussed their concept and the related ones to have a concrete def

Different parameters were investigated to evaluate their effect on the process removal efficiency of COD and color, by using different H₂O concentration, UV power, multi-step addition of HO2, and air bubbling. As a result, the color can be removed completely within 20 minutes, and the COD removal of approximately 90% can be achieved within 40 minutes of UV illumination. This process favors the H₂O, addition in one step rather than in four steps. Supply of oxygen does not enhance the process removal efficiency. The overall result indicates that the operating cost (chemical and electricity) to reduce the COD to below 80 mg/l is 0.93 US$/m3

Reservoir characterization is an important component of hydrocarbon exploration and production, which requires the integration of different disciplines for accurate subsurface modeling. This comprehensive research paper delves into the complex interplay of rock materials, rock formation techniques, and geological modeling techniques for improving reservoir quality. The research plays an important role dominated by petrophysical factors such as porosity, shale volume, water content, and permeability—as important indicators of reservoir properties, fluid behavior, and hydrocarbon potential. It examines various rock cataloging techniques, focusing on rock aggregation techniques and self-organizing maps (SOMs) to identify

Reactive powder concrete is an attractive new concrete technology for structural design applications. The technology has been used for different structures with several advantages. Strengthening and retrofitting structures using FRP has grown rapidly in the last decades to upgrade structures because of the gradual material degradation over time. The technique was applied mainly for conventional normal and high-strength concrete and steel. This study is conducted to study the performance of bonding interface among reactive powder concrete substrate and CFRP sheets using different parameters, including bond length, bond width, and bond–slip relations. Concrete prisms with dimensions of (25 x 25 x 75 mm) were adopted in t

The study aimed to find the best amount of cellulose nanofibers to add to heat-cured denture base material to enhance its mechanical characteristics. Cellulose nanofibers (CNF) were added to the  polymethyl methacrylate (PMMA) denture base in several weight percentages (0%, 0.5%, 1%, 1.5, and 2%). A probe sonicator was used to mix the monomer with the cellulose nanofibers for around 5 minutes. Impact strength, transverse strength, and shore D surface hardness were the three groups that were classified afterward according to the trials conducted. Descriptive statistics, including means, standard deviations, and bar chart visualisations, were utilised to analyse the data. The findings indicate that the mean values of impa

The effect of the addition of sustainable materials and alkali-resistant glass fibers on perlite concrete is studied in this paper. The research includes slump, density, flexural strength, split tensile strength, compressive strength, and thermal conductivity tests. This specimen was cast using Portland cement, metakaolin (which replaced 15% of the cement weight as pozzolanic materials), a combination of coarse and fine perlite aggregate, superplasticizer, and local ash (which was employed as a filler and replaced by cement weight in a ratio of 10%). The ratio of cement to perlite (volumetric ratio) was 1:2. The concrete reinforced 1% alkali resistance glass fibers by volume of concrete. The results show that adding su

Six (1000*1000 mm²) slab specimens were cast and tested as two-way simply supported slabs previously (three under monotonic loading and three under repeated loading) are used in this research. The tested specimens consist of one solid slab and two voided slabs with the following variables (type of slab (solid and voided), presence of steel fibers (0% and 1%), and the presence of GFRP layers). This paper presents the results of tested slabs and the 3D-Nonlinear finite element (ABAQUS program) is proposed to verify the tested slabs under monotonic and repeated loading. The process of modeling the structure components of the tested slabs will be discussed in detail, including the creation of the parts, model mate

The main objective of this work is to propose a new routing protocol for wireless sensor network employed to serve IoT systems. The routing protocol has to adapt with different requirements in order to enhance the performance of IoT applications. The link quality, node depth and energy are used as metrics to make routing decisions. Comparison with other protocols is essential to show the improvements achieved by this work, thus protocols designed to serve the same purpose such as AODV, REL and LABILE are chosen to compare the proposed routing protocol with. To add integrative and holistic, some of important features are added and tested such as actuating and mobility. These features are greatly required by some of IoT applications and im

AsSanna'f Marsh is one of the southern Iraqi Marshes. It is considered as a seasonal marsh. During rainy season, the marsh feeders start to fill the nearly empty region of the marsh and the water levels start to increase gradually. After the water level reaches a specific value, it starts to flow toward Al Huwayza Marsh. Studies on the hydrological properties of AsSanna'f Marsh are rare and there is a lack of hydrological data of AsSanna’f Marsh feeders. Generally, this paper was prepared to predict missing hydrological data, a procedure was developed and applied for this purpose, and to be used with the available hydrological and topographical data for modeling and analysis the hydrological properties of AsSanna’f Marsh. The topogra

Up to date, in many foundation design problems (especially for piles foundation), the shear strength (skin friction) between soil and construction materials of the foundation was usually estimated or correlated without any direct methods for measurement.
The modern trend is to establish skin friction coefficients through laboratory experiments in which the factors influencing the results may be controlled quantitatively.
In this study strain controlled Direct Shear Tests were performed using shear to simulate the shear behavior area between concrete (foundation materials) and undisturbed over consolidated silty clay, to determine the shear strength of soil – foundation interface, considering the following variables : (1) Concrete

The aim of this paper is to integrate mobile phones into LANs by connecting the two parties and providing the mobile with a transparent access to the services and resources hosted by the LAN. Quick assessment of the typical related approaches for accessing LAN (like WLAN and Bluetooth BNEP) shows that they are inappropriate for mobile phones. The paper further inspects the LAN access approach based on Bluetooth PAN Profile and marking up its potential drawbacks. A modified approach is proposed and implemented by altering the access nature or model from peer-to-peer communication to a client/server service providing, and switching from BNEP to RFCOMM protocol.

The hydrodynamics behavior of gas - solid fluidized beds is complex and it should be analyzed  and understood due to its importance in the design and operating of the units. The effect of column inside diameter and static bed height on the minimum fluidization velocity, minimum bubbling velocity, fluidization index, minimum slugging velocity and slug index have been studied experimentally and theoretically for three cylindrical columns of 0.0762, 0.15 and 0.18 m inside diameters  and 0.05, 0.07 and 0.09 m static bed heights .The experimental results showed that the minimum fluidization and bubbling velocities had a direct relation with column diameter and static bed height .The minimum slugging velocity had an

The research focuses on examining the level of harmony in the formal characteristics among the elements of the traditional Baghdad alley, from individual components to the entire area. Numerous studies have highlighted the unity and cohesion in the urban structures of traditional Arab urban environments, including Baghdad alleys, despite the diversity of the urban landscape. The study's theoretical aspect focuses on the visual features of the traditional urban environment, emphasizing the concept of diversity within unity. This is explored through specialized studies in the field. The applied part of the study involves using fractal geometry tools, specifically the box-counting method, to measure the degree of harmony an

Land use is the human modification of the natural or terrestrial environment into a built environment such as fields, pastures, and settlements. Baghdad, like most cities in the world, suffers from many urban problems, especially the problems associated with the disparity in the distribution of land uses and deficiencies in their distribution according to scientific standards and foundations, such as the problem of pollution and overpopulation. Karrada was chosen because it represents a large urban center in Baghdad, with about 1 million people spread over about 72 km2.  The aim is to assess land use in Karrada. In addition to the analysis of land uses in the study area, and the study of changes that occurred in those u

In this paper, a proposed method based on real-coded genetic algorithm is presented and applied to solve multiple load flow solution problem. Genetic algorithm is a kind of stochastic search algorithm based on the mechanics of natural selection and natural genetics. They combine the concepts of survival of the fittest with genetic operators such as selection, crossover and mutation abstracted from nature to form a surprisingly robust mechanism that has been successfully applied to solve a variety of search and optimization problems. Elitist method is also used in this research, and blending models are implemented for crossover operator. In the proposed work, five busbars typical test system and 362-bus Iraqi National Grid are used to dem

Bubbled slabs can be exposed to damage or deterioration during its life. Therefore, the solution for strengthening must be provided. For the simulation of this case, the analysis of finite elements was carried out using ABAQUS 2017 software on six simply supported specimens, during which five are voided with 88 bubbles, and the other is solid. The slab specimens with symmetric boundary conditions were of dimensions 3200/570/150 mm. The solid slab and one bubbled slab are deemed references. Each of the other slabs was exposed to; (1) service charge, then unloaded (2) external prestressing and (3) loading to collapse under two line load. The external strengthening was applied using prestressed wire with four approaches, wh

Experimental research was carried out to investigate the performance of CFRP wrapping jackets used for retrofitting twelve square reinforced concrete (CR) column specimens damaged by exposure to fire flame, at different temperatures of  300, 500 and 700ºC, except for two specimens that were not burned. The specimens were then loaded axially till failure after gradual or sudden cooling. The specimens were divided into two groups containing two main reinforcement ratios, ρ= 0.0314 and ρ= 0.0542. This was followed by the retrofitting procedure that included wrapping all the specimens with two layers of CFRP fabric sheets. The test results of the retrofitted specimens showed that the fire damaged RC

The use of biopolymer material Chitosan impregnated granular activated carbon CHGAC as adsorbent in the removal of lead ions  pb.2+   from aqueous solution was studied using batch adsorption mode. The prepared CHGAC was characterized by Scanning Electronic Microscopy (SEM) and atomic-absorption  pectrophotometer. The adsorption of lead ions onto Chitosan-impregnated granular activated carbon was examined as a function of adsorbent weight, pH and

This paper presents a new design of a nonlinear multi-input multi-output PID neural controller of the active brake steering force and the active front steering angle for a 2-DOF vehicle model based on modified Elman recurrent neural. The goal of this work is to achieve the stability and to improve the vehicle dynamic’s performance through achieving the desired yaw rate and reducing the lateral velocity of the vehicle in a minimum time period for preventing the vehicle from slipping out the road curvature by using two active control actions: the front steering angle and the brake steering force. Bacterial forging optimization algorithm is used to adjust the parameters weights of the proposed controller. Simulation resul

Aeroelastic flutter in aircraft mechanisms is unavoidable, essentially in the wing and control surface. In this work a three degree-of-freedom aeroelastic wing section with trailing edge flap is modeled numerically and theoretically. FLUENT code based on the steady finite volume is used for the prediction of the steady aerodynamic characteristics (lift, drag, pitching moment, velocity, and pressure distribution) as well as the Duhamel formulation is used to model the aerodynamic loads theoretically. The system response (pitch, flap pitch and plunge) was determined by integration the governing equations using MATLAB with a standard Runge–Kutta algorithm in conjunction with Henon’s method. The results are compared with

Bitumen aging contributes to main pavement distress due to the changes in rheological, chemical, and physical characteristics of bitumen. Mainly, aging process can be divided into two categories, the first category namely short-term aging takes place during the heating up of bitumen and aggregate, mixing, transportation, laying down, and compaction. While the second category of aging takes place during the service life of pavement which is denoted as long-term aging. Consequently, researchers’ focus is to simulate bitumen aging in the lab by developing lab-accelerated methods to simulate the process of bitumen aging and studying the rate of change before and after aging. This article reviews these methods and compares
