Abstract: The recreational open spaces, within the residential urban fabric in the cities of Iraq in general and in Mosul in particular are suffering from being neglected because of their weak activities, mentioning to their low efficiency of occupancy. Therefore, there is an urgent need to study some of their urban properties, including the physical and spatial configuration, and its impact on their occupancy.Most of previous studies on this specific urban spaces didn’t mention the impact of such physical and spatial factors on its efficiency. This research studies the effect of the physical and spatial configuration on occupancy of recreational open spaces within the residential urban fabric, on the efficiency of their functional performance, positively and negatively, by conducting a series of analysis and the use of certain techniques, such as the (Space Syntax), classification of urban squares based on spatial organization, as well as an on-site survey of the users, which would be taken up in the practical part of this research through the election of a number of open recreational spaces of different residential urban fabric in Mosul.

Abstract: One of the main aspects in urban design is to choose the appropriate location for the dominant buildings because of its effect on the image ability, legibility and way finding in addition to the aesthetic aspect. Administration building of University has an important symbolic value through its main function and responsibility that includes managing of all components of the campus. The relationship between visual organization properties of administration building of University and the building location represents phenomena that lacks adequate research endeavors, despite its importance in organizing Campus site. So there is a need for a clear and precise vision of this relationship. Four universities were selected as case studies, include designed university as Baghdad University, and accumulatively grown universities as Mosul University, Cairo University and Kufa University. Visual analysis and space syntax approach were applied to determine and compare the visual attributes of administration buildings of Universities using relevant softwares. The study outcome showed some similar and different indicators among universities.

These criteria were a land use, water resources,slope, geology, environmental impact, hydrology, control area and linear engineering structure. Questionnaire from was distributed to a group of decision-makers and specialists in the field of design and road construction to determine the relative importance of these criteria spatial using Pairwise comparison was conducted after building a hierarchical structure to evaluate the standards and using the analytic hierarchy process (AHP). The study results showed that the highest relative importance criteriawas the water sources 26% when the ratio of the consensus of 44% , followed by the uses of the land value of 23% when the ratio of the consensus 70% , while value of the relative importance was the standard environmental impact by 5 % and the rate at a consensus of 65% . The high consensus at (70%) of the uses of the land and slope of the grounds are important criteria during the design process. The study also showed less consensus and important standard for linear engineering structure where tracks matched by consensus (47%) of the importance of (7%).

Abstract: A simple and practical model balance system was developed to predict the advanced distance with time in level border irrigation systems, this model proposed the surface and subsurface water storage during irrigation as one unit with a single shape factor changed with advance time, the proposed shape factor was calculated at different time intervals by using 13 field test including all the involved with surface irrigation process. The obtained values of the shape factor in addition to the other variable was grouped in dimensionless terms, the shape factor was correlated with these terms by using (SPSS) statically analysis program. The proposed model was evaluated with afield data and compared with other models, the results shows good agreement between the field data and the proposed model, the study also conclude that that the advance affected significantly by manning roughness, flow rate and kostiakov coefficient in different degrees the analysis also show that the change in discharge have the largest effect on advance distance among the other variables.

Abstract: This study search’s the removal of turbidity from water by electrocoagulation technique. Bench scale with continuous flow system was designed the system consists of electrocoagulation reactor with volume (2 L), flocculation basin and sedimentation basin with volumes change due to the change in detention time of electrocoagulation. Aluminum plates (17×8) cm were used (3 plates) as the anode and (4 plates) as the cathode, the spacing between plates was taken (1 cm) and the temperature of water was kept at (25°C). The study investigates the effects of some operating parameters such as, electrical current that ranging from (0.1 – 2) A, detention time of electrocoagulation (1 , 5 , 10 , 20) minutes and initial turbidity variety of the raw water (10 , 25 , 100 , 300) ntu upon the residual turbidity. Experiment result shows that the residual turbidity decrease with increase value of the electrical current for all values of initial turbidity. Also, the residual turbidity decrease with increase time of electrocoagulation for all values of initial turbidity specialy in (0.1 , 0.25 , 0.5) A, when the electrical current increase to (1 , 1.5 , 2) A , the change in residual turbidity was small specialty in time between (10 – 20) minutes. The results also proved that increasing the initial turbidity lead to increase the residual turbidity.

Abstract: Unsteady mixed convection heat transfer of a laminar fluid flow in ventilated enclosure was studied numerically. Thebottom horizontalsurface was considered isothermal, whereas the other walls were considered adiabatic. The fluid enters into enclosure through a hole located at the bottom of the left vertical wall and exits from the top of the opposite wall. The mathematical model is governed by two dimensional conservations of mass, momentum and energy equations. The numerical simulations of the fluid flow and heat transfer were investigated with a range of Reynolds number (50-500) and Richardson number (0-10), with Prandtl number fixed at 0.71. The effect of the aspect ratio on the fluid flow and heat transfer characteristics in the enclosure was studied in three different values (0.5, 1, 1.5 ). The numerical results showed that the maximum value of the average Nusselt number was achieved at aspect ratio of 0.5. Also, the average Nusselt number increases with the increase of Richardson and Reynolds numbers for whole different cases.

Abstract: This study has investigated the modeling of shear strength using the artificial neural network (ANN) approach. The Results of 128 samples of steel fiber reinforced concrete (SFRC) beams without stirrups were collected gathered and used to generate a four-layer feed forward neural network using the back-propagation learning algorithm available in the MATLAB program. Nine parameters for SFRC beams, namely, beam height, beam depth, beam width, steel cross-sectional area, shear span-to-depth ratio, concrete compressive strength, volume fraction, fiber length, and fiber diameter, were considered as input variables for the ANN. ANN output representing the shear strength were compared with those observed experimentally using regression analysis approach. Results indicated that the ANN modeling technique is effective in simulating the behavior of SFRC beams. In addition, a parametric study shows that shear span, compressive strength of concrete, volume fraction, and fiber length are playing the major role in the behavior of SFRC beams.

Abstract: In this paper, a new method is proposed for QRS complex detectionusing a special kind of IIR filter called bi-reciprocal lattice wave digital filter (WDF). This filter has some attractive features that make it more efficient than other types of filters.One of these features is its sufficient linear phase in the passband, thus yielding a perfect reconstraction condition. Therefore, it is not required to cascade the designed filter with anall-pass filter for correcting the phase distortion. The coefficients of the designedfilter areachieved by simulating the FIR response suggested in [1].A least square method solution is usedin such simulation with a genetic-based algorithm.A simplified structure for the designed filter is accomplished with less-complex realization. 50records of European ST – T ECG database is classified into four classes (Normal, Left Bundle Branch Block (LBBB), ST segment elevation, and Left Ventricular Hypertrophy (LVH)). By applying the designed filter coefficients into neural network classifier, the results show that the accuracy of the classification process is 95.9 %.
