Lean techniques are used in order to eliminate waste, waits and increased patient satisfaction. Lean defines the wastes but not identify which waste should be eliminated for this reason Arena 14.00 Rockwell simulation software used to analyze the ED performance. Patient's flow chart was created to study the total duration of patients stay in the ED, the waiting time and the utilization of resources based on the lean principles approach. The results identified and concluded from simulation model were as the follows, the patient flow time was (65) minute for each patient (total time that patient spent from the beginning of his entry into the ED until he discharged), while patient throughput in morning shift about (241) patient (the number of patients attending the department during morning hours). On the other hand, the utilization ratio of doctors, nurses, receptionists were (83 %, 13 %, and 95 %) respectively. This is demonstrating the applicability and effectiveness of lean principles to ED processes using the simulation model as a pre-implementation tool for improvements in health care sectors.&nbsp;</p> Dhuha Kadhim Ismayyir, Aseel Jameel Haleel Copyright (c) 2019 Journal of University of Babylon for Engineering Sciences https://www.journalofbabylon.com/index.php/JUBES/CopyrightandLicensing https://journalofbabylon.com/index.php/JUBES/article/view/2636 Fri, 01 Nov 2019 00:00:00 +0000 Transformation Towards Self-Built Architecture https://journalofbabylon.com/index.php/JUBES/article/view/2637 <p>The concept of transformation has been invested in architecture using bio-simulation as a means to produce architecture that responds to different influences. In a similar way, the building transforms the behavior of living organisms in its adaptation to environmental influences during the construction of its structure. The need to clarify the concept and approach to the transition towards self-construction architecture, which expresses the goal of research in building a theoretical framework to study the research problem and extracted from the various design and implementation methods in architectural projects and to reach a number of key and secondary vocabulary and applied to selected projects and conduct measurement. Using mechanics of growth and manufacturing using advanced digital materials is the future orientation of<br>architecture to be self-construct.</p> Faten Yaseen Ali, Safaa Al-Deen Hussein Ali Copyright (c) 2019 Journal of University of Babylon for Engineering Sciences https://www.journalofbabylon.com/index.php/JUBES/CopyrightandLicensing https://journalofbabylon.com/index.php/JUBES/article/view/2637 An Attempt to Find Suitable Parameters for Coagulation-Flocculation Processes for the Treatment of Water https://journalofbabylon.com/index.php/JUBES/article/view/2639 <p>Water turbidity is considered as an important physical parameter of water quality. It is a good indicator for assessing the required treatment for the drinking water. In the present study, a standard jar tests were conducted to obtain the most suitable parameters for the design of coagulation-flocculation process. Results proved that the best rapid mixing time (t<sub>1</sub>), slow mixing time (t<sub>2</sub>), and settling time (t<sub>3</sub>) are 1, 50 and 60 min respectively. The maximum removal efficiencies of turbidity were 99.31, 98.56 and 94.72% at t<sub>1</sub>,&nbsp; t<sub>2</sub> and t<sub>3</sub> equal to&nbsp; 5, 50 and 60 min respectively, with pH values ranged from 3.7 to 8.9. The measured values of water turbidity removal perecentage were represented using an artificial neural network (ANN) technique and the results signified that there is a remarkable agreement between experimental and predicted values with coefficient of determination (R<sup>2</sup>) and root mean squared error (RMSE) equal to 0.932 and 0.5501 respectively.</p> Jabbar H.

Within this paper, the normal intensity of RZ robustness modulation and the Modified-Duobinary-Return–Zero modulation (MDRZ) on FWM was investigated. In addition, the performance of the system under the fiber length variation effect was evaluated under the impact of (80) Gbps data rate for both types of modulation format. The results showed that the RZ modulation introduces a minimum (FWM) power of (-54) dBm at (70) kms fiber length, while MDRZ offers FWM power of (-44) dBm at the exactly same fiber length, In-term of the performance of the system at channel 4, a minimum BER was noticed in normal RZ modulation which equals to&nbsp;&nbsp; 2.27´10 - 43 at (-35.31) dBm received power. However, the BER was 4.98´10-15 at the same received power and channel, in the existence of MDRZ modulation format. The finding reveals the progress of RZ modulation in reducing the FWM crosstalk and enhances the WDM system performance even with the impact of high data rates.</p> Noora Salim Copyright (c) 2019 Journal of University of Babylon for Engineering Sciences https://www.journalofbabylon.com/index.php/JUBES/CopyrightandLicensing https://journalofbabylon.com/index.php/JUBES/article/view/2641 The Experimentally Studying of Solid Desiccant Wheel Performance Combined with the System of Air Conditioning https://journalofbabylon.com/index.php/JUBES/article/view/2643 <p>The aim of this study was to study the performance of the system of solid desiccant dehumidification to decrease the latent load on cooling coil for the system of air-conditioning and advance the thermal comfort, thus reduce the energy consumption. Rotary desiccant wheel contains a silica gel as a solid moisture absorbent material has been utilized in this study. The wheel was a diameter of 55 cm and a thickness of 20 cm. The wheel cross sectional area is divided into two parts in aspect ratio. The large part represent dehumidification or absorption process, in this section moisture is removed from the humid air by the silica gel. While the other part represent desorption or regeneration process in this section moisture was absorbed from the humid air by the gel of silica in the first process will be removed from it. The experimental results demonstrates that the utilizing of the desiccant wheel will reduce significantly the thermal load on the cooling coil by reducing the latent load of the passing of humid air respectively via the wheel and the cooling coil</p> Zainab M.

This work presents a new model for solving a problem of vibrations in cantilever beams with attaching F<sup>2</sup>MC tubes as patches that provide passive vibration control.&nbsp; Mathematical model of the compound system of patches of F<sup>2</sup>MC tubes integrated on the beam was derived. The governing equations depend on Euler-Bernoulli beam theory and Lekhnitskii’s theory of elasticity. This study examined new model’s performance for damping with variation in tube size; bonding position of the patches on the beam in two different cases: &nbsp;on the beam through changing the distance between two them; one patch above and the other under the beam. Analytical results demonstrate that the proper tuning the size of tubes as a function of inner layer radius; and integration points are basic parameters for passive vibration control. They achieve reductions in response amplitude at the first vertical bending mode effectively.</p> Shireen O. Mohammad, Nazhad A.
