<span>In this paper, the flow and local scour variation around two submerged and unsubmerged tandem piers are studied using 3D flow model where the upstream pier is submerged while the downstream pier is emergent. The model uses a finite-volume method to solve the non-transient Navier-Stokes equations for three dimensions on a general non-orthogonal grid. The k turbulence model is used to solve the Reynolds-stress term. The numerical model solves the sediment continuity equation in conjunction with van-Rijn’s bed-load sediment transport formula to simulate the bed evolution. The 3D flow model is verified through experimental study in a non cohesive bed material in an experimental flume. The different causes of local scour around two submerged and unsubmerged piers are simulated well, such as bow flow, down flow, horseshoe vortex, pressure variation and lee-wake vortex. It is found from this study that the maximum local scour depth by interaction between two tandem submerged unsubmerged piers depends on submersion ratio of upstream pier, the densimetric Froude number, the longitudinal distance between piers and the ratio of pier diameter to channel bed width. The maximum scour depth decreases by increasing the submerged pier height then begin to increase by increasing the submerged pier to a height larger than half the water depth and in general the maximum scour depth is less than that of two unsubmerged piers. The results show good agreement between simulation and experimental results. Also, empirical equations are developed for computing the maximum scour depth due to the interaction between two submerged unsubmerged piers with circular shapes as a function of submergence ratio, piers spacing, densimetric Froude number and channel width to pier diameter ratio.</span>

<span>This study is done to discuss nonlinear static behavior for cable-stayed bridges, hence develop a set of consistent design as well as a feasibility study of long span cable-stayed bridges over Nile River. In order to accomplish this goal, a thorough investigation of important key design parameters to determine the behavior of cable-stayed bridge and identify any gaps in current knowledge is done to be filled in order to enable the formation of a consistent set of design recommendations. Three span cable stayed bridge has been analyzed, the effects of the variation of different key design parameters: cross section of cables, cable layout either fan or harp pattern, pylon height to span ratio and mechanical properties of deck and pylon on the straining action of the bridge elements are investigated. The loads on the cable stayed bridge are a symmetrical load such as the own weight of all structural elements and live loads. The results related to the major factors to choose the ratio between the bending stiffness of a deck and axial stiffness of the cable to reduce bending moments and deflections in the deck and pylon are presented and discussed. Finally, some conclusions related to the cable stayed bridge’s analysis/design are drawn.</span>

<span>Deterioration of Egyptian desert roads in Upper Egypt (Al-Minea area) were investigated through developing deterioration model. This model requires collecting data related to time periods for different progressive deterioration stages for road surfaces. Ten road segments located in desert roads were studied. Each road segment has an average length of 500 meters. The progressive deterioration stages of road surface were monitored for each segment in term of Pavement Condition Index (PCI) and plotted against time for each road type. Least square regression analysis has shown that a quadratic function represents the best fit for the collected deterioration data with a coefficient of determination (R2) ranges from 0.95 to 0.96. The developed deterioration prediction model can be used to predict future deterioration of desert roads.</span>

<span>Modern production of high quality concrete is closely connected with wide use of different types of admixtures, by which using of small doses allowed to obtain the required physical, technical, exploitation and economical properties of concrete. The use of concrete in water or wastewater tanks has many benefits such as strength, long service life and cost effectiveness. It has emerged as the dominant construction material for the infrastructure needs of the twenty-one century. In addition to being durable, concrete is easily prepared and fabricated from readily available constituents and is therefore widely used in all types of structural systems. The challenge for the civil engineering community in the near future is to realize projects in harmony with the concept of sustainable development and this involves the use of high performance materials and products manufactured at reasonable cost with the lowest possible environmental impact Physical, chemical absorption and chemical reactions may occur between the admixtures and the hydrating components of cements. Physical and chemical changes occur when admixtures such as accelerators, retarders, water reducers, and superplasticizers are added to the cement - water system. Mechanisms of the action of admixtures, changes in water demand, viscosity, setting, slump loss, shrinkage, kinetics of hydration, micro structure, strength and durability of fresh and hardened cement pastes can be explained by the interaction effects. Therefore, the main purpose of this research is to study experimentally the mechanism effect of a proposed local and economical additive on both the compressive strength and durability of concrete. The experimental results showed that, the optimum composition of all components of the suggested admixtures (BM 2010) containing wastes from petroleum industries and silica fume and naphthalene sulfonate was successfully and experimentally achieved. This paper focuses on the experimental studies about the possibility of producing new chemical organic admixtures containing in their compositions industries wastes by testing 180 cubic concrete specimens to propose the best-suggested admixture effect on their compressive strength and durability under these aggressive environmental conditions.</span>

<span>ECP 203[1] recommended two values for the compression steel ratio in rectangular R.C. section. The first ratio is 10 % of main reinforcement steel as a minimum value to contribute in reducing deflection, however the second ratio is 40 % of main reinforcement steel as a maximum value in an attempt to make the section is under reinforced section, however there is no specific definition for these ratios with the different grade of concrete. In this paper the effect of compression steel ratio on the behavior of a simple span R.C. beam such as bridge girder has been studied. Numerical study of R.C bridge girders under static and dynamic loads has been performed taking the effect of changing compression steel ratio with different concrete grades. Moreover the effect of increasing the steel compression ratios on the failure mode and ductility of concrete has been investigated. It is concluded that using high ratio of compression steel has no influence in case of high strength concrete beams compared with the normal strength concrete beams.</span>

<span>There is a growing trend in constructing high-rise buildings towards eliminating the extra space above false ceilings by passing service ducts through openings in the floor beams. Such an arrangement of building services leads to a significant reduction in the dead space, and results in a more compact and economical design. However, including openings in the web of a reinforced concrete beam induces high stress concentration at opening corners, reduces beam stiffness, and alters the simple beam behavior to a more complex one. Therefore, this work investigates the effect of openings on the statical behavior of high strength L- section reinforced concrete beams. For this purpose, thirteen reinforced concrete beams of L- section, with web openings, were tested. The studied parameters were: opening position, concrete compressive strength, length of the opening, reinforcement around the opening, and shape of the opening (rectangular, square, and circle). Cracking and ultimate loads were recorded; deflections at the position of mid- span and at the center of the opening were measured. Pattern of cracks and modes of failure were observed It was found that, decreasing the compressive strength of the used concrete, or the steel reinforcement around the opening, and increasing the opening length have a great effect on cracking and ultimate loads, pattern of cracks, and maximum induced deflections and strains, i.e., bearing capacity, and deformation capacity of such tested beams.</span>

<span>Passive earth pressure against retaining wall depends on a number of factors such as, soil friction angle φ, soil wall friction angle δ, backfill angle (ground surface inclination behind wall β), inclination of wall face on horizontal α, and surface of rupture. Several theories have been developed to overcome this problem, i. e., determination of the coefficient of passive earth pressure using the plane surface of rupture. One of the important parameter which affect the coefficient of the passive earth pressure is the surface of rupture. In the present paper, formulation is proposed for calculating coefficient of passive earth pressure on a rigid retaining wall undergoing horizontal translation based on surface of rupture consisting of log-spiral and linear segments assisted by computer program (MATLAB program). The present study is compared with coulomb’s results. The comparisons of that the present study predicted values of earth pressure are much less than those of coulomb’s values specially if δ≥ 0.3 φ. These results agree well with another research. In order to facilitate the calculation of coefficient of passive earth pressure, using the proposed equations, a modified coefficient of passive earth pressure is provided. It is a function of (φ, δ, β, α).</span>

<span>The paper reports a study of slurry erosion of carburized AISI 5117 steel using whirling-arm rig. The study is mainly focused on studying the erosion wear resistance properties of AISI 5117 steel after carburizing at different impact angles. The mechanisms of erosion wear at different impact angles are presented using SEM examination of eroded samples. In addition, the SEM images of eroded samples at different stages are presented for better understanding of erosion mechanisms at different angles. The tests were carried out with particle concentration of 1 wt %, and the impact velocity of slurry stream was 15 m/s. Silica sand having a nominal size range of 250 – 355 μm was used as an erodent. The results showed that, carburizing process of steel increased the erosion resistance and hardness compared with untreated material for all impact angles. The erosion resistance of AISI 5117 steel increases by 70, 57, 60 and 36 % at an impact angle of 30º, 45º, 60º and 90º, respectively as result of carburizing, i.e. the effectiveness of carburizing was the highest at low impact angles. Treated and untreated specimens behave as ductile material, and the maximum mass loss appears at impact angle of 45o. Plough grooves and cutting lips appears for acute impact angle, but the material extrusions are for normal impact angles. The erosion traces are wider and deeper for untreated specimens comparing by the shallower and superficial ones for the carburized specimens.</span>

<span>This paper addressed the sensing coverage problem in wireless sensor networks. A sensing coverage range estimation scheme is presented and analytically validated. In presence of channel fading, we have also proposed a Lagrange based, optimal power assignment algorithm that guarantees a predefined probability of detection over the sensor-to-fusion center communication channels at a given probability of false alarm. Analytic results reflect the effectiveness of the proposed algorithms which tries to make the network operational point falls in the feasible SNR region at the lowest (optimal) transmission energy consumption.</span>

<span>A high accuracy medical image registration is needed to achieve an efficient medical diagnosis and computer aided surgeries, so that a novel region based medical image registration approach is presented in this paper. This approach consists of four sequential steps, image segmentation, point correspondence using a modified artificial immune system, point selection and finally LMS technique is used to estimate the warp parameters. The proposed approach provides a high accuracy and it doesn’t require any additional treatment or feature extraction as some other methods do. To demonstrate the effectiveness of the proposed approach it tested for many image pairs and it is compared with many registration algorithms such aspoint-based image registration using an artificial immune system (AIS),ICP and RANSAC algorithms.</span>

In this control system the rotor flux and the electromagnetic torque are estimated based on the rotor voltage and currents measurements. Control system response is based only on wind speed profile. The control strategy is based on keeping harmonics at low order under the constraint of unity rotor power factor and also under decreasing torque ripples. Results are obtained from simulations show a very fast dynamic response for the control system with sensorless operation under wind speed variation.</span>

<span>The importance of this tool is showing the role of media edification policies and mechanisms for developing cultural awareness of architectural heritage. Every society has its culture and originality that must be enhanced and developed by spreading its cultural, intellectual, and urban products of all times; as well as portraying positive behavioral approaches that help enhance the principle of participation for maintaining heritage environments and the national identity. As the current conservation authorities in several developing countries lack a clear vision by which the local community cultural awareness, of the heritage environments and their conservation processes, may be increased; hence came the idea of this research to address the important media and edification policies that may be executed by the conservation administration in cooperation with people of the society. The aim of the research is to establish media and edification polices that aid in raising the community's heritage awareness within managing universal conservation processes of heritage environments, in order to create more interest by the local and external community members of the importance of maintaining heritage environments, and convey such interest actively to the next generations. Such policies would help create new initiatives and, in the same time, achieve direct social and economic benefits to the community. For the purpose of achieving the aim, the research will adopt the analytical and theoretical methodologies. In the first part, the research will focus on introducing concepts related to conservation management and different conservation policies; including media edification policies. The second part focuses on studying and analyzing the requirements of media edification in heritage environments, determining the potentials and methods of such policies, and specifying the targeted categories and their interaction with the conservation administration in managing conservation. The research concluded that media edification policies are important for helping conservation administrations carry out their different roles within heritage environments. Also, the integrated execution of edification policies helps create community partnerships between society members for conserving their heritage environments, as well as creating partnerships between society members and architectural conservation administrations. Hence, such edification processes need to be organized and activated regularly in all heritage environments. All society members must be sufficiently enlightened, regardless of their stature, to be engaged in the conservation processes and assume the moral, ethical, and practical responsibilities for the local urban heritage.</span>

<span>In the light of the status of the maintenance system of the basic education’s buildings in Egypt, limitations and problems they face. This paper presents a proposed methodology for the maintenance of the basic education’s buildings in particular, and provide clear evidence for the workers in this field, including the principal elements that needed to be taken into account when prepare a plan of the preventive maintenance of the educational building. The preventive maintenance of the basic education’s buildings needs a range of tools and methods in order to succeed.
