By tracking the criticism history of knowledge in all fields including architecture it can be noticed that some theories control on the other because of its regenerative feature to become an objective approach to any kind of criticism because they provide it with a quiet compass inside the artistic production in order not to loose its way towards the target. One of those theories the intentionality theory emerged which linked to the indications related to literary, artistic and architectural production both, the fact that architecture is a communication system can be a language consisting of vocabulary and rules, which the intention can have a prominent role in it. Hence the research problem is (the absence of the overall concept of the role of intentionality theory in reading current architecture production), hence the goal of research is to (see the ranges of influence of the theory of intentionality in reading architectural output). For the purpose of achieving the goal of Search went to put the cognitive framework of the theory of intentionality and its connections in the architecture within the specialized studies and then check the hypothesis, which stipulates (there is the influence of the theory of intentionality in reading architectural production), and through the application of a number of the elected project down to the final conclusions.

The Iraqi water shares from Lesser Zab River (LZR) and Diyala River (DR) is greatly affected by Iranian intensions and attitudes because of its geographic positions as a source country. Consequently, it becomes so warrant to adopt some arrangements that regulate the water relations between those two countries. The current study is an attempt toward finding a reasonable solution for the potential conflict between Iraq and Iran over LZR and DR. The water facts on those rivers are pointed out that the annual average flows recorded during 70’s of the last century were 6.2 and 6.0 BCM for LZR and DR respectively. However, and over the last 20 years or so, these flows have been reduced to only 4.8 and 3.3 BCM respectively. The calculated future demand in the Iranian side of the LZR is estimated to be 0.175 BCM, while the demand in the Iraqi side is around 7.2 BCM. As far as DR is of concern, Iran consumes 3.1 BCM and Iraqi needs are 9.9 BCM. It is clear that the future demands is surpassed the expected future supply from the two rivers. One can conclude that the conflict between Iraq and Iran over LZR and DR is imminent. Part-I of the study is concerning with the application of Graph Model for Conflict Resolution (GMCR-II) which is rooted in game theory and system engineering approaches, for the purpose of resolving the potential water conflict between Iraq and Iran over LZR and DR. While Part-II, is to find a simplified method to facilitate the application of the solution that emerges from the part-I in a practical and systematic manner. This will be the subject of a subsequent paper.

This study investigates the behavior of a rectangular footing subjected to inclined and eccentric load on geo-grid reinforced sand by using laboratory modeling. Small model was used to simulate the behavior of rectangular surface footings (length to width ratios of the footings were equal to 1, 1.25, and 1.5). The effect of the eccentricity and inclination of applied load on the bearing capacity, settlement, horizontal displacement and tilt were investigated. The load eccentricity varies from (0, 0.05B, 0.1B to 0.15B) and the load inclination varies from (00, 50, 100, 150) . The dry sand is reinforced by multiple layers (1, 2, 3, 4 and 5) of Geo-grid. The results illustrated that by increasing the number of reinforcement layers, the bearing capacity increased, but there is an optimum value (5). In general, for central, inclination and eccentricity loading the results indicated that by increasing the number of reinforcement layers (N) the bearing capacity increased while settlement, horizontal displacement and tilt decreased.

The value of prisons is characterized by the total meanings contained within, and the similarities between their walls as a result of certain events or actions that took place between them and which have their impact and their association with the memory of the community and formed an important part of their social identity, Although some of these buildings have many components historical, and heritage-related events in its spatial history, which are reliable development potentials to restore sustainable economic growth by perpetuating its and making it as guidance and informational documents for society. But it suffered from mismanagement, guidance and use by The competent authorities led to the result of these symbolic places atrophy and thus the loss of the privacy of her event. Hence the research problem, which was (the lack of knowledge available about the nature of the investment of the symbolic value of prisons in the commemoration of her memory, so as to ensure their interaction and community outreach) In order to achieve the research objective, which is to (create a comprehensive theoretical framework for the nature of commemorating the prisons by investing their symbolic value and achieving their interaction with the society that contains them). This requires the adoption of an analytical descriptive approach based on building a comprehensive theoretical framework, and then analyze results, To give the conclusions to explore the nature of the commemoration of prisons according to their symbolic data.

During last four decades, Iraq had faced multiple political crisis which reduced its ability to encounter emerging environmental problems. As of now, wastewater contamination is one problem that the country is lacking proper infrastructures capable of dealing with. The aim of this study is to evaluate the performance of wastewater treatment plants in the country over time. Barakia wastewater treatment plant is one of the major wastewater treatment plants in Al-Najaf province in Iraq. The plant was taken as a case study to test the trend of the environmental performance. Parameters of BOD5, COD, TSS, PO4, NO3, NH3, O&G, H2S, and CL- were used to test the performance. Ten years data were collected and evaluated. The plant showed downward ability to reduce contaminants efficiently, and recently, the plant turned to be one of the major polluters in the province. Overloading of the plant beyond its design capacity, high frequent power outage, absence of retrofitting advanced treatment such as filtration and nutrients removal, and lack of maintenance and repair parts were the main causes of the plant’s poor performance. Iraq, due to its current economic situation may need an international assistance to reverse this trend of degradation.

This research aims at the evaluation of concrete compressive strength by non destructive testing techniques namely, the maturity concept test in addition to the hammer (rebound), and the ultrasonic scan tests. A comparison of results is then to be conducted to estimate the accuracy of the method. The real ability and the introduction of the maturity concept test is the main focus of this work since it takes into consideration the combined effect of temperature and age on the mechanical properties of concrete, as well as the interaction between site and laboratory testing . A total number of 14 cylinders and a square slab of 900 x 900 x 70 mm of the same mix were tested for the maturity strength relationship with heat sensors imbedded into the specimens slab and two additional cylinders also at the age of 56 days the same concrete was tested by the hammer and ultrasonic scan, the results showed good agreement giving a compressive strength of 32.2 MPa, 28.0 MPa and 29.7 MPa for the maturity, ultrasonic and hammer tests respectively.

The present study utilized an experimental tests to investigate the effects of using High Strength Concrete (HSC) on ultimate resistance, deflection and slip of steel-concrete composite beam under monotonic and repeated loads. Sixteen beams divided into four groups having concrete with compressive strength of 25, 42.6, 43.3 and 43.9MPa investigated experimentally. Results indicated that the use of HSC increases the carrying loading capacity of the beams by about 18.82 % and 52.91 % under monotonic and repeated loads, respectively. The beam resistance decreased under repeated load in comparison with monotonic load by about 5 % to 28.53 %. Use the fiber increases the ultimate strength by about 10 % to 28.65 %, and decrease the deflection and slipping by 15 % and 26.5 %, respectively. The ultimate strength estimated experimentally are less than the AISC-LRFD specifications’ formulas.

The visual analysis of moving objects has been an important computer vision research area. As the number of vehicles is increasing on the roads, the need for accurate detection of vehicles is rising. A hybrid segmentation method that combines background subtraction, threshold segmentation, morphological operators, and watershed segmentation is proposed in this paper.
The shadow has a vital effect on the performance of many fields like tracking, classification, detection, and shape analysis. The shadow presented in the data used in this paper was successfully removed using watershed and shape analysis. Since the connected vehicles touch each other in the boundary only, the watershed transform can correctly isolate these touching cars. The proposed system overcomes the over-segmentation drawbacks of the watershed transform by applying it to the gradient of the image rather than the image itself.
Finally, shape analysis is used to remove large shadow parts which lead to the detection of the vehicles only. An accuracy detection rate of 97% was reported from the highway video which is astonishing result compared to existing methods. The proposed algorithm was coded using MATLAB R2014b programming language. The accuracy and simplicity of the proposed system make it applicable for real-time traffic surveillance Applications.

This paper mainly presents the producing of self-compacting high performance concrete (SCHPC) incorporating silica fume (SF) as a supplementary cementing material. Various percentages of replacement by weight of cement were tried including 5, 10 and 15%. The water/ binder (W/B) ratio and total binder content for all types of mixes were fixed at 0.30 and 484 kg/m3, respectively. The fresh properties of SCHPCs were investigated by slump flow, T50, V-funnel flow time and L-box (blocking ratio) tests. The hardened properties of SCHPCs were tested for bulk density, compressive, splitting tensile and flexural strengths and ultrasonic pulse velocity (UPV). The results showed that there was a progressive decrease in flowability properties of SCHPC with increasing SF content. Whereas, test results the compressive, splitting tensile and flexural strengths and UPV increased with increase in SF levels. Furthermore, SCHPC mixture contains 10% cement replacement of SF exhibited higher values of compressive strength, splitting tensile strength, flexural strength and UPV compared with control mix of SCHPC for 28 days. The final conclusion is that SF can be used as a sustainable supplementary cementing material in producing self-compacting high performance concretes.

The collapse of embankments, dams and slopes in the Arab world has become a phenomenon need to stand on the causes and consequences. The magnitude of the devastation due to Liquefaction phenomenon need to take the necessary precautions to reduce potential losses. Investigation of the (naturalist and imitation) of slopes and embankments stability is a hard geotechnical errand. Therefore embankments numerical study is implementing to diminish the situation of falling flat slants and rashes during shaking through appropriate FEM software. The FOS and liquefaction potential trend are obtained using finite element technique “Newmark” deformation analysis. The conformity of the analysis is verified by inquiry a layered slope of two altered soil deposits exposed to earthquake shaking. The conclusion from the study proved that the soil stratified trend has an immediate influence on the stability of the slope due to shaking and it is the simplest technique to reduce shaking effect. All combined phenomena which have delivered serious harm all over the world concentrated under quake examined under a record of 0.1 to 0.5g with particular case study to explore liquefaction zones due to the quake. Changeability of textural properties of soil layers affecting FOS and liquefaction has been examined for embankments. This study comes to put a highlight on Mosul Dam problem and give some suggestion and conclusions to its problems.
