     summary: Neural Network PID Self Tuning For undetermined system’s model, experimental methods such as Ziegler-Nichols tuning rules may be used to design PID controller. The conventional PID controller in the robot manipulator is replaced by NN self tuning PID controller so as to achieve trajectory tracking with minimum steady-state error and improving the dynamic behavior (overshoot).

     summary: It is probable that similar microstructural considerations also apply to the preferential corrosion of weld metal, but in this case, the situation is further complicated by the presence of deoxidation products, their type and number depending largely on the flux system employed. In seawater, for example, the corrosion rate for a weld made using a basic-coated consumable may be three times as high as for weld metal from a rutile-coated consumable.

     summary: Effect of Applide Potential and Temperature on The Anodic Current Density For the purpose of obtaining more information, we will study the current term anodic current density versus applied potential and this is what is shown in Figure 3 where the anodic current density increases with the applied potential and temperature. In addition, the increase in temperature will lead to increase the kinetic energy of the ions and make it move more quickly and therefore it will be helpful to increase the speed of precipitation reactions, and this whole is the main reason for the increase in anodic current density.

     summary: Therefore, it can be concluded that the shot peening time has the highest impact on the hardness values at lower and higher slenderness ratios, whereas the slenderness ratio has, in general, no significant influence on the hardness at lower and higher shot peening times. Different ranges of shot peening time (STP) and critical points of slenderness ratio which is between the long and intermediate columns, as input factors, were used to obtain their influences on the fatigue life and hardness, as main responses.

     summary: Corrosion behavior of these materials was investigated by Potentiostat to estimate corrosion resistance and compared with the most resistant material represented by SS 316L. The experiments were carried out in 0.01N of NaOH solution at four temperatures in the range of 30–60 o C. Polarization resistance values which calculated by Stern-Geary equation indicated that the MAX phase materials more resistant than SS 316L. Also cyclic polarization tests confirmed the resistivity of MAX phase materials through disappears of hysteresis loop. Abstract This work involves the manufacturing of MAX phase materials include V2AlC and Cr2AlC using powder metallurgy as a new class of materials which characterized by regular crystals in lattice.

     summary: When the pressure within a thermal insulation material is lowered to a value, the percentage of heat transfer by heat conduction of the interstitial gas between the particles becomes negligibly small when compared with the percentage heat transfer by radiation and conduction over the bulk material. The dominant mode of heat transfer when choosing a specific thermal insulation material at atmospheric pressure is by heat conduction of the interstitial gas between its particles, whereas the heat transfer by radiation is negligible.

To compare between the standard deviation of the two outputs the results shown that std of FIR output of HFN is approximately similar to std of the desired signal and less than of IIR output std but approximately similar to std of desired signal that mean that the deviation of the results from the true curve is smaller in case of FIR filters to remove both noises than the IIR filters.

     summary: The fraction of total solvent in the raffinate phase decreased with increasing oil to solvent ratio in raffinate layer because the increasing solvent power (solvent to charge oil ratio) at constant temperature gives high extraction efficiency and as solvent power increased, the solvent in raffinate decreased proportionally with the decreasing of raffinate yield of oil which keeps the increase of R. The reverses of extract phase in which solvent increased, in the solvent power also increased.

     summary: Potentiodynamic polarization techniques were used for making electrochemical measurements on the alloys and couples in artificial saliva at 37oC. Corrosion potentials, corrosion rates and general corrosion behavior, including passivation range and breakdown potentials, were determined for all materials and couples. Corrosion parameters were interpreted in these media which involve corrosion potential( Ecorr) and corrosion current density (icorr), since the results of (Ecorr) indicate that Oxalate ions are more corrosive than other materials while the results of (icorr) indicate that NaCl is more corrosive than other materials.

     summary: 24- 33 Enhancement of Hybrid Solar Air Conditioning System using a New Control Strategy Ahmed Abed Mohammed* Raed Ayad Abduljabbar** *,**Department of Mechanical Engineering / University of Technology *Email: 20187@uotechnology.edu.iq **Email: me.21148@uotechnology.edu.iq (Received 14 January 2018; accepted 25 April 2018) https://doi.org/10.22153/kej.2018.04.002 Abstract Enhancement of the performance for hybrid solar air conditioning system was presented in this paper. Ha and Vakiloroaya, 2012 [3] estimated the optimum refrigerant temperature entering the condenser in hybrid solar air conditioner system by proposing a by-pass line together with a three-way proportional control valve that installed after the compressor to control the refrigerant flow rate and enhance the performance of the system, results show that the average COP by using the optimal set-point values is higher than the commonly-used design by 6.7%.

     summary: The liquid phase flow pattern in bubble column was qualitatively described by Kawagoe K, (1976) and by Schumpe A, and Grund, G.R. (1986), who identified the existence of two streams in the column: one heading upwards driven by the buoyancy of gas bubbles and the other carrying the liquid down. The study includes the effect of gas velocity and the addition of alcohols on gas hold-up and mass transfer coefficient in bubble column with draught tube when the length of the column is 1.5m and the ratio of the draught tube diameter to the column diameter equals 0.5 and the air dispersion into the base of the draught tube using a multi hole tuyere is equivalent to a diameter of 0.15 mm and has a free sectional distributor area of 61%.

     summary: Abstract A mathematical model is developed which predicates the performance of cylindrical ion exchange bed involving comparing of axial dispersion model for cation exchange column with different assumption, this model permits the performance to predicate the residence time within the bed with the variance, axial dispersion and Pecklet No. to indicated deviation from plug flow model. Several workers studied dispersion with porous media, the first who deal with axial dispersion O. Levenspiel 1958 when he study the commercial application of step experiment and he design chart to ease the calculation of axial dispersion, H. Dunck 1966 study he effect of axial dispersion on the elution band of nonlinear equilibrium chromatography and the effect change in axial dispersion coffin with elution velocity , O .Levenspiel 1972 found the c-curve in closed vassal for various extend of back mixing as predicated the dispersion model , C.Y. Wen, T. Tfan l.t. 1975 point that the axial dispersion provides satisfactory description only of mixing model that not deviated significantly from plug flow, R. Shinnar 1987emphasized that the application of axial dispersion model for Pe No. value for less than 10 is not advised, Iman Hahider Mahdi Al-Khwarizmi Engineering Journal, Vol. 5, No. 4, PP 1-12 (2009) 2 C. T. Tan1987 the value of dispersion coefficient are either assumed or calculated from molecular diffusivity and radial pore velocity prior to incorporation into the model the radial dispersion R. Y. A. Ofoli, 1991 reported that axial dispersion model is suitable for analysis of reactor up to 30% conversion , Y. Tsaur and D. Shallcross 1997 developed a model to simulate ion exchange performances with fixed annular bed which take into account the radial dispersion in effect in both solution and exchange phases, however the model assumes instantaneous equilibrium between ions in the solution and exchange phases existed throughout the exchanger, M. A. Barros and Aszpla 2002 analyze the Cr +3 ion to exchange in NaA zeolite in presence of K + ,Cu +3 ion in binary and ternary cation exchange with evaluate the dimensionless variance of Breakthrough curve which useful to estimate the axial dispersion of the bed, M. Doung and D. Shallcross 2002 developed theoretical model of fixed bed ion exchange and obtained the model for pure dispersion without ion exchange performance, I. M. Abu-Reesh and B.l F. Abu- Sharkh 2003 make a comparison of axial dispersion and tank-in-series models for simulating the performance reactors they found that tank-in-series models presents computational advantages compared to dispersion model , Doung M. and Shallcross D.2005 made a series of experiment in wedge-shape cell ion exchange for both Na-and H- form bed with different flow rate lead to indicated dispersion coefficient function of pore velocity and radial distant of the wall.

     summary: Microstrip bandpass filters designs based on the 1 st and 2 nd iterations have shown size reductions of about 40% and 64% as compared with the conventional microstrip square ring bandpass filter designed at the same frequency and using the same substrate material. Abstract A novel fractal design scheme has been introduced in this paper to generate microstrip bandpass filter designs with miniaturized sizes for wireless applications.

     summary: It uses an unsupervised adaptive neural network with GHA algorithm to extract the principal components that in turn, are used by Capon method to estimate the DOA, where by the PCA neural network we take signal subspace only and use it in Capon (i.e. we will ignore the noise subspace, and take the signal subspace only). Suboptimal methods are more prevalent than the ML technique when the signal_to_noise ratio and number of samples are both not too small, because the suboptimal methods involve solving only a one-dimensional maximization problem and subspace (signal subspace or noise subspace).

The distillation process of extract phase feed and cracked extract phase liquid were done in a distillation device which behaves as one tray and the distillation is done at atmospheric pressure.
