Lateral Deflection of Cantilever Secant Pile in Soft Clay.
The performance of deep excavations is governed by the ground conditions such as soil stiffness and in situ stress conditions. Cantilever secant pile wall (CPW) is one of the retaining systems which are used to support deep excavation. Its lateral deflection has great importance as it shows the behavior of CPW in the soil. Two dimensional analysis (2D) and three dimensional analysis (3D) may be used to get the lateral deflection in numerical solution. This study is focused on 2D and 3D analysis for CPW in soft clay. The finite element software "Abaqus/CAE-v6.9" has been used in the analysis. The 2D study analysis takes into account the different CPW depths and its diameter effect. The construction stages effect on the lateral deflection have been studied also. The 3D study analysis takes into account the different excavation geometry “the length and width of the excavation” effect, also different depths for CPW in 3D analysis have been studied also. The results showed that longer CPW has larger lateral deflection while CPW diameters have no effect on lateral deflection. Later deflection in one construction stage may be double that of previous stage. Also it was found that later deflection in three dimensional (3D) analysis is higher than the 2D analysis by three times. This confirms that 3D analysis of CPW in soft clay leads to more accurate results than 2D analysis.

Strengthening and Repair of Self Compacting Concrete Beams.
While there is abundant research information on ordinary concrete beams strengthening or repairing with FRP, relatively little data on the behavior of self-consolidating concrete (SCC) is available. Carbon Fiber Reinforced Polymers laminates (CFRP) was investigated for strengthening and repairing SCC and high strength self compacting concrete (HSSCC) beams subjected to one midpoint load in in order to compared to beams made of normal concrete (NC) and normal high strength self compacting concrete (NHSSCC) at the same conditions respectively. To demonstrate the concept, this paper presents results of a laboratory investigation of 24 beams (150x200x1600 mm) on the behavior of self compacting concrete strengthening and repairing with one layer of CFRP laminate and subjected to one midpoint load, including the effect of using 8 different mixes to study the effect of mix proportions on rapped CFRP beams behavior. Test results showed that the addition of CFRP laminate to the tension surface of the beams demonstrated significantly improvement in stiffness and ultimate load capacity of beams. The response of control and strengthened beams were compared and evaluated by experimental and theoretical calculations. It was observed that ductility indexes of SCC and HSSCC beams were more efficient than NC and NHSC respectively. Load carrying capacity of control, strengthening and repairing self compacting concrete beams was closed to traditional concrete beams (about 90-95%). The paper also highlighted the crack pattern of all cases of beams which indicated more distribution and smaller crack amplitude for strengthened beams with respected to the control beams.

Design of Self Compacting Concrete Using Artificial Neural Networks.
Application of artificial neural networks (ANNs) model to design the mix component of self compacting concrete (SCC) with desirable properties, compressive strength and slump flow, is described in this research Artificial Neural Networks (ANNs) have recently been introduced as an efficient artificial intelligence modeling technique for applications involving a large number of variables, especially with highly nonlinear and complex interactions among input/output variables in a system without any prior knowledge about the nature of these interactions. Various types of ANN models are developed and used for different problems. In this paper, an artificial neural network of the feed-forward back-propagation type has been applied for the prediction of self compacting concrete mixtures. The main targets are SCC components and the inputs interred are compressive strength and slump flow. Due to the complex non linear effect of compressive strength and slump flow properties on the SCC components, the ANN model is used to predict the components of SCC parameters (mix components). SCC component parameters were outputted according to a multi mixes taken from 34 researches (1-34] related with self compacting concrete which contains the compressive strength and slump flow test results. Mix component values are considered as the aim of the prediction. A total of 225 specimens were selected from the laboratory results of about 34 researches. The system was trained and validated using 150 training mixes chosen randomly from the data set and tested using the remaining 75 mixes. About 20 mixes of experimental SCC not found in the entered data were performed experimental in order to simulate the program and compare between experimental and predicted mix design. Results indicate that SCC components can be predicted with reliable values to the experimental results using the ANN method.

Intelligent Framework for Sewer Pipes' Performance Evaluation, Optimal Strategy for Rehabilitation & Failures Prediction Using GIS, AI and DSS.
The treatment of water and wastewater utilities problem represents the best usage of our resources on the national economy. One of the problems that face Egypt now is the ad-hoc failure of water &wastewater utilities. The rapid growth of its population yearly increased both water demands and water disposal. Serious strategies for water development & improving water disposal have to be established to prevent this failure which leads to both private and public benefit. Besides Wastewater utilities face an aging workforce, combined with the declining maintenance budget which presents challenges to infrastructure management agencies to sustain acceptable performance levels and to meet the high demands of these systems. Need for new techniques to improve the efficiency of managing civil infrastructure systems is evident. Many infrastructure management software tools have been developed to address the increasing complexity of infrastructure systems. However, most of these tools were developed for stand-alone use, and thus lack an integrated and comprehensive view to the infrastructure management process and the ability to interoperate with other tools. This research presents an integrated component-based framework that aims to integrate different tools and technologies into one coherent environment to enable infrastructure agencies to address various aspects of infrastructure management from an integrative perspective. One of the most important integration is the integration between GIS and Al .So integration with ANN will be used 10 develop a prediction model for pipe failures and with GA will lead find near optimal solution for sewer rehabilitation according to certain budget.

Effects of Aspect Ratio on Heat Transfer and Pressure Drop in Stationary and Rotating Two-Pass Rectangular Channels with Smooth Wall.
A computational study is performed on three-dimensional turbulent flow and heat transfer in a rotating and non-rotating two-pass smooth rectangular channel with aspect ratio (AR) of 2:1 and 1:2. The focus of this study is to investigate the effect of rotation, mean velocity of coolant fluid and the aspect ratio on the flow and heat transfer characteristics. A Reynolds-averaged Navier Stokes (RANS) turbulence model was employed to solve the NS-equations. Computations were performed with Reynolds number (Re) ranging from 19,000 to 25,000, rotation number (Ro) from 0 to 0.1, inlet coolant-to-wall density ratio ( p/p) was 0.39. The finite volume code, FLUENT ANSYS 6.3 was used to predict the flow and heat transfer. Computational domain was meshed with fine grids to resolve the near wall viscous layer using GAMBIT grid generator. Theoretical results obtained for stationary channels are in good agreement with experimental results of other investigators. Also, it is indicated that the aspect ratio, rotation number and fluid velocity has a great effect on the characteristics of flow, heat transfer and pressure drop in case of rotating two-pass rectangular channels. Moreover it is seen that there is a reversible fluid flow at higher rotation number.

Adaptive Urban Design Bases of College Schools with Learner's Psychology.
In the design and planning process of large schools, great interest has been noticed in the physical side; regardless of the psyschological one (human side), as well as its unsuitability with our local society and environment. Societal and environmental factors are believed to have the greatest impact on the psychology of users, especially children: because the shape and design of internal and external spaces experienced by the child overrules his ethical and perceptional limits, and contributes positively or negatively in the development of the child's concepts. This applies as well to the stage of late childhood and adolescence period in different limits and approaches. On the other side, the concern in the physical term appears in different forms such as the stereotypes schools designed by the General Authority for Educational Buildings in Egypt or in reusing of old mansions ignoring the standard architectural design basis or the humanitarian aspects. This paper aims to provide a new approach towards school design by synthesizing and analyzing the urban design bases of large schools and their relevance and effect on the psychology of users, taking into account their age variation (from 4 to 18 years); in order to achieve the objectives of the educational, cultural, and recreational activities.
