So measuring of supply chain performance in such circumstances can be considered as a crucial effect and it is implemented in this paper. This research aims to estimate supply chain performance measurement based on Fuzzy Analytical Hierarchical Process. In real application, the performance of organization estimated based on different factors and these factors vary in impact on performance depending upon policies and strategies of organization. The importance of each factor was identified by applying Fuzzy Analytical Hierarchical Process technique. Two phases fuzzy logic rule were applied, the first phase i.e. fuzzy inference system was used to identify performance indicator of each factor by using its value and importance. The second phase was started by using second fuzzy inference system to identify supply chain performance measurement by integration of all factor indicators which obtained from first inference rule. The developed approach provides an effective tool for evaluation of supply chain performance measurement and real case study was presented in dairy industries.</p> 2018-11-25T00:00:00+00:00 ##submission.copyrightStatement## http://journalofbabylon.com/index.php/JUBES/article/view/1801 Flexural Behavior of RC One-Way Slabs Strengthened with Fiber Reinforcement Cementations Matrix, FRCM. 2018-11-25T06:42:49+00:00 Ali Hadi Adheem ali.hadi@kit.edu.iq Isam M. Ali ali_isam@ymail.com Mustafa S. Shaker aldulaimy.mustafa93@gmail.com <p>Numerical simulation performed in this paper to explore the flexural behavior of RC one way slab strengthened with fiber reinforcement cementations matrix (FRCM). Three dimensional finite element analysis was performed by using ANSYS (17.2). The main issues focused in this paper are (1) the effect of FRCM fabric types on the flexural behavior of strengthened RC slab in terms of both ultimate capacity and deflection, (2) effect of variables compressive strength value of the concrete slab and (3) number of fabric layers for composite material effect. The results showed that the fabric type had a clear effect on the flexural behavior of the strengthened slab. The parametric study also revealed that the flexural strength increases with increasing the compressive strength of concrete when the failure is represented by crushing of the concrete strut. In addition to, the number of fabric layers for composite material had a clear effect on the behavior of RC slab, but to a specified number because then the failure is determined by the action of the concrete in the compression zone.</p> 2018-11-25T00:00:00+00:00 ##submission.copyrightStatement## http://journalofbabylon.com/index.php/JUBES/article/view/1802 Dynamic Analysis of Gough Stewart Robot Manipulator by Using Lagrange Formulation in Matlab Software 2018-11-25T06:50:19+00:00 Hassan Mohammed Alwan 20071@uotechenology.edu.iq Riyadh Ahmed Sarhan me.21328@uotechnology.edu.iq <p>In this paper, Gough Stewart parallel manipulator with six-degree of freedom used as a model to derived the inverse kinematics equations and inverse dynamic equations. The inverse kinematic problem is very simple to derive then used to computed the jacobian matrix and the lengths of the linkages to determine the path trajectory of the moving platform. The dynamic equation based on the Lagrange method by calculated the kinetic and potential energies for the model. The dynamic equation inserted in Simulink block as Matlab file lead to computed the forces of the linkages at any time of simulation and can be used to explain if the path contain a singularities where the forces increasing very quickly in singular point compare with other points during the path of the moving platform.

Abbass kais12a@yahoo.com Ahmad Hadadd a_talib11@yahoo.com <p>In light of the rapid technical technological development of technology and its dominance over the joints of life, the need for intelligent design was born as an important episode of the technological development in the 21st century. This concept became dominant in all other design types, including design with its various disciplines such as architectural design, urban and other. It is capable of dealing with architecture &amp; urban problems and solving them, and it has the ability to study the relationship between architectural buildings and transportation, social and political planning thinking, its relation to the urban and economic aspects, and the provision of safe and easy means of freedom and of the transition between the spaces. And provide special spaces for people to enable them to meet and meet all their social requirements. In order to shed light on the dimensions of smart urban &amp; architectural design, it is necessary to build on a global research ground that explores the concepts of urban intelligence. The research aims to study the concept of smart cities, sustainability, dynamic design, etc., because of its strong association with the concept of intelligence on the one hand and the urban &amp; architectural design concept, Global government interest in this issue as in the European Parliament, for example. One of the most important elements of urban design is the need to deal with the city or region in a comprehensive way away from reading the elements separately to reach a suitable design for that region. A good urban design is the close link between city planning and architectural design. And that the body of the city is not integrated except in the presence of public spaces and to broadcast the spirit is not only interest in the health of its streets, it is necessary to participate people in the design of the city, but through a questionnaire on the opinion of design thought, there should be a collection of as many ideas as possible to reach Type of integration with urban structures. The research presents a research hypothesis that artificial intelligence may be the concept of smart cities, which is influential in rephrasing the dimensions of the concept of urban design according to the theory that came from the Matthew Carmona through a theory that calls for integration in the dimensions required for the architectural and urban design of the social space suitable for man.</p> 2018-11-25T00:00:00+00:00 ##submission.copyrightStatement## http://journalofbabylon.com/index.php/JUBES/article/view/1804 The Importance of Digital Modeling to Understand the Functional Change of Urban Landuses 2018-11-25T07:06:30+00:00 Naseer A.

The effect of the different promoter silica gel powder on R-134a gas hydrate formation has been investigated in the isochoric system experiment. It is noted that the purse media have a significant effect in increasing the speed of nucleation as well as improving the growth of hydrate. In the experiment, the effect of silica gel powder was studied to determine their effect on the composition and cooling capacity of 134 hydrates. From kinetic models were obtained many objective functions such as the amount of gas consumed (∆n), the growth rate (r (t)), and conversion of the water to hydrate. The gas consumed (∆n) of binary system increased with increase initial pressure of hydrate formation, also the hydrate growth rate (r (t)) and increase conversion of water to hydrate increase &nbsp;when this the first time that the effect of silica gel pweder on these functions with average active size (900) nm, BET surface area (0.65) m<sup>2</sup>/g, pore volume 210.85 cm<sup>3</sup>/g and average pore size (900) nm that studied for use in industrial applications and water treatment. The improvement of hydrate growth is marked by the addition of silica gel powder, which in turn increase the solubility of hydrate gas and reduce the contact angle. In addition,&nbsp;&nbsp; silica gel powder positively the contact with the gas through the increase of the interaction surface between gas and water and this increases the rate of formation of hydrate.</p> 2018-11-25T00:00:00+00:00 ##submission.copyrightStatement## http://journalofbabylon.com/index.php/JUBES/article/view/1806 Impact of Transport Systems Operating in Cities' Centers on Urban Development (Environment) 2018-11-25T07:22:24+00:00 Mohammed kareem mohessen Archmkm1983@gmail.com Bahjet Rashad Shahin Archmkm1983@gmail.com <p>The transport systems operating within the city in general and its center in particular have a great impact on urban development within the city's sustainability.

The Pneumatic vacuum elevator represents a new concept evolved from the idea of pressed air applied in the pneumatic elevator replaced by a vacuum air idea. The pneumatic vacuum elevator is able to transport people between building floors without using any cables, counterweight, or pulleys. A simple and low cost construction and implementation for an Electro-pneumatic vacuum elevator system prototype is presented in this paper. The elevator system prototype is constructed with three floors to elevate a maximum load of 6kg. Programmable Logic Controller (PLC) of (LS\GLOFA-G7M-DR30U) series with (16) inputs and (12) outputs programmed with Ladder diagram software is used for the fully automated the elevator system. The idea of the proposed elevator system may be predicted to be widely spread in the low-rise residential buildings.</p> 2018-11-26T00:00:00+00:00 ##submission.copyrightStatement## http://journalofbabylon.com/index.php/JUBES/article/view/1811 The Ethics of Decoration in Architecture 2018-11-28T02:08:55+00:00 Abdulla Sadoon Salman Abdullasadoon@yahoo.com Enas Salim Abdulahaad enas_salim76@yahoo.com <p>The decoration has been associated with various human achievements since ancient times and has been considered by some of theses &nbsp;as an additional, non-mandatory , can be probability&nbsp; remove , subtract and dispensable.
