Abstract: This research presents a comparison study for physical properties between Iraqi and Iranian perforated clay bricks. 300 samples of perforated clay bricks are randomly selected from the production of five Iraqi factories and five Iranian factories which are available in local markets ( 30 bricks from each factory ). All samples are selected and tested by standard methods according to Iraqi standard specification No. 24/1988. The results of the tests are evaluated according to the requirements of the Iraqi standard specification No. 25/1988. The physical properties that have been tasted (according to the requirements of Iraqi specifications) are; general appearance, deviation of dimensions from standards, concave and convex, absorption, compressive strength and efflorescence. The results show that Iraqi bricks are better than Iranian bricks in deviation of dimensions from standards and absorption while Iranian bricks are better than Iraqi bricks in general appearance, concave and convex, compressive strength and efflorescence. When all tasted properties are evaluated with general requirements of Iraqi specifications for general evaluation, results show that Iraqi bricks are better than Iranian bricks and all samples of bricks can be classified within either class B or C and no unite within class A.

Abstract: The performance of asphalt concrete pavement depends on the bitumen properties, asphalt concrete mixtures volumetric properties and external factors such as traffic volume and environment.Overlay is one of the quickest preventive maintenance techniques that apply to retard asphalt pavement deterioration and prolonged service lives. This study focuses on prepare good performance and flexible modified thin hot mix asphalt used as an overlay. Styrene-butadiene rubber (SBR) at three contents (3, 6 & 9 % by asphalt weight) were used either alone to modify local asphalt penetration grade 40/50. Properties of modified and unmodified asphalt binder (Penetration, Softening point, Flash point and Ductility) were examined. Performance of modified and unmodified asphalt mixtures was evaluated through Marshall, Indirect Tensile Strength and Wheel Tracking Test. Test results showed that all properties of the base asphalt binder and asphalt mixes were improved by the addition of the modifier. The best improvements in the modified binders and modified mixes were obtained at 6% SBR. Stiffness of modified asphalt mixes were improved at 6% SBR was introduced. Marshall stability was increased by 26% and flow was decreased by 12.5% at 6% SBR. Resistant of the modified asphalt mixes to rutting was increased by 61% at the same modifier content. The three mix types prepared and tested according to Marshall Method. Marshall Stability and Indirect tensile tests were conducted on Marshall specimens. Wheel tracking test were conducted on (50×10×5 cm) AC mix beams.

Abstract: The mechanical behavior of filled elastomeric (rubber and rubber-like) materials is known to be incompressible, or nearly-incompressible, hyperelastic and time-dependent, or viscoelastic. This complex behavior of rubbery materials needs more understanding, and good knowledge is required for such behavior in order to achieve a good constitutive modeling for better design of a rubber component for a specific application. This work concentrated on studying the effect of carbon black type on the mechanical properties of rubbery material characterization. To do this, different tests were performed on filled rubber with three different kinds of carbon black N326, N375, and N660. All tests were performed at room temperature. The tests include rheometer tests, hardness tests, tensile tests, specific gravity tests, compression tests, relaxation test, and cyclic loading tests. Tensile tests were done with different strain rate, relaxation tests done under different mean strain. Tensile stress-stretch curves were generated from the test data at strain rate ranging from 10 to 500 mm/min and several transitions associated with strain-induced crystallization were observed in all materials. The filled rubber became stiffer when the strain rate increased from 10-200 mm/min, and became more compliant when the strain rate increased from 200 to 500 mm/min. Hardness and specific gravity tests showed that rubber filled with carbon black N375 is harder and has specific density more than other two types of filled rubber.The mechanical compression set tests, which performed on rubber with three kinds of carbon black and found that compression set for rubber filled with carbon black N375 is more than the other two kinds of filled rubber. Relaxation stress-time curves were generated from test data at varying mean strain ranging (50% to 200%) from the effective length of the specimen, at constant strain rate (200 mm/min). Generally, it was observed that the stress reduces with time when the specimen hold at specific strain. This reduction is faster at strain between 50% and 100% than the strain between 150 to 200% till reaches steady state. Series of cyclic tension tests were carried out at room temperature on a rubber compound under strain rate 200 mm/min. All these cyclic strain-controlled experiments showed that the filled rubber materials, used in the present work are time-dependence with hysteresis. It came out that hysteresis for rubber with carbon black N375 is more than the rubber with other two kinds of carbon black

Abstract: The growth in various types of industries together with population growth has resulted in enormous increase in production of various types of waste materials, world over. The creation and disposal of non-decaying waste materials have been posing difficult problems in developed as well as in developing countries. The efforts to find useful applications of some of the waste products in highway construction have given encouraging results. The use of Tetra-Pak (TPA) containers to pack food of various kinds including milk, juice, meat, etc. has become a common practice. To produce packaging materials, TPA uses paperboard (73%), plastic (22%) and -for aseptic packages- aluminum foil (5%). However the disposal of the Tetra-Pak in large quantities has been a problem and is of great concern, particularly in big cities. In case it is possible to find useful application for the waste TPA, there will be substantial scrap value for this waste product and therefore they will be collected and sold by interested persons, instead of being littered or thrown out in the dust bins or into the road side drains. The present study investigates the benefits of using shredded Tetra-Pak in binder layer flexible pavement mix. A (1-6)mm in particle pieces of TPA had been added. The mix had been tested by Marshall testing method. Mix volume relationships, Marshall Stability and flow with the different percent of shredded TPA were recorded. A control binder mix is used with (5)% asphalt content for comparison and the same asphalt content used for all specimens. The research concluded that using TPA in the range of (1-1.5)% in HMA increase the Marshall stability, flow and air voids and decrease in voids filled with asphalt. For (2)% there was decrease in stability, air voids and voids filled with asphalt (VFB) and increase in flow. In (3-above)% the mix start scattered in the test.

Abstract: In the present study, two procedures of capacity-yield are applied to estimate the reliability of Dokan reservoir using data generation techniques. These procedures are the probability matrix (Gould) procedure, and the behavior analysis. Vulnerability, and resilience, are also calculated in the second procedure .The data is generated by using four approaches ,namely ,Thomas-Fiering model with log –transformation (TF-log), Two-Tier model (TTM), modified Two-Tier model (MTTM) and modified Fragment model (MFM).These models are tested and compared with the historical data. It is concluded that among these four procedures the Thomas-Fiering model with log –transformation is the most appropriate for representing the Dokan reservoir inflow .Three factors are examined to determine their influence on the minimum storage estimate .These are the length of stochastically generated sequence, the initial state of storage ,and the starting month. The results reported here show that sequences as long as 10,000 years or more may be needed to minimize the effects of these factors.

Abstract: This paper presents the simulation of two dimension a half-vehicle self –tuning active suspension system to simultaneously improve vehicle ride comfort. A validated 4-DOF of vehicle linear model was used to study the performance of passive suspension system and compared with the developed active suspension system. The governing equations of motion for the self- tuning active suspension was derived and used to reduce the effect of disturbances to the dynamics performance of the vehicle, which appear when the vehicle excited by a semi-circular sinusoidal bump road of a (0.1 m) height. The performance of passive suspension and the self-tuning active suspension are demonstrated by simulations and specially the vertical acceleration and the vertical root mean square (RMS) acceleration to observe the effect of the proposed system to the ride comfort. The active suspension system introduced in this work show good results for improving the ride comfort

Abstract: This paper presents a Particle Swarm Optimization (PSO) method for determining the optimal proportional – integral-derivative (PID) controller parameters for governor control of a synchronous generator .The proposed approach has superior features, including easy implementation, stable convergence characteristic and good computational efficiency. The synchronous generator is modeled and the PSO algorithm is implemented in simulink of matlab. The simulation results demonstrates the effectiveness of the designed system in terms of reduced settling time, peak overshoot and oscillations of frequency devaition. The results are compared with traditional trial and error tuning of the PID controller. Which gives in the PSO-PID controller: maximum positive overshoot of frequency deviation =0 and negative overshoot of frequency deviation =-0.042, Settling time= 7sec. Whereas, in conventional trial and error tuning: maximum positive overshoot of frequency deviation =0.002 and negative overshoot of frequency deviation =-0.03, Settling time= 11sec.

Abstract: Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient. In particular, it can be used to join highstrength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. In this paper the investigation is made on friction stir welding process for joining of copper alloy. Friction stir welding experiments was performed using different pins (pin with straight boundary and pin with curved boundary). Welding joints efficiencies were found for each set. Mechanical and microstructural analysis has been performed experimentally on the welding zone. Non- linear numerical models was built in ANSYS software to simulate the thermal history of a workpiece undergoing friction stir welding by a moving heating source. An accurate prediction of temperature fields is evident. Exclusive result for effect of rotating a friction stir tools with respect to boundary conditions on stress-strain curves is presented. The results shown that the friction stir welding with pin of curved boundary is more efficient than that of straight boundary
