Using Travelling Salesman Principle to Evaluate the Minimum Total Cost of the Iraqi Cities

The traveling salesman problem (TSP) is a well-known and important combinatorial optimization problem. The goal is to find the shortest tour that visits each city in a given list exactly once and then returns to the starting city. In this paper we exploit the TSP to evaluate the minimum total cost (distance or time) for Iraqi cities. So two main methods are investigated to solve this problem; these methods are; Dynamic Programming (DP) and Branch and Bound Technique (BABT). For the BABT, more than one lower and upper bounds are be derived to gain the best one. The results of BABT are completely identical to DP, with less time for number of cities (n), 5 ≤ n ≤ 25. These results proof the efficiency of BABT compared with some good heuristic methods. We are suggesting some additional techniques to improve the computation time of BABT for n ≤ 80.

The environmental impacts of industrial zone in cities

ABSTRACT Studying the positive and negative effects resulted from the industrial projects and laying down the comprehensive planning bases to the urban development projects which insure retaining the social, economic and environmental development, taking in to consternation the time factor within the planning process which is considered the most important factor that determine the extent of the efficient selection to the site and not interpenetrate in the industrial activities and efficiency and calculating its future expansions away from the residential areas. It is more favorable to plan the industrial areas of apparent pollution outside the bounds of the basic plan to limit the negative effects on the environment and providing

Post-Operative Computed Tomography to Evaluate the Accuracy of Thoracic and Lumbosacral Spine Pedicular Screw Fixation

 Background: pedicular screw fixation is rapidly becoming a widely used method of spinal instrumentation. Despite improvement in design of instruments and surgical technique and the use of intra-operative fluoroscopy, pedicle cortical perforations occur endangering nearby neurovascular or extra vertebral structures.
Objective: This is a prospective (consecutive cases study) designed for Evaluation of incidence of pedicle screw misplacement in our study sample, compare our results to what is published in literature.
Patients and Method: This study involved 25 adult patients ( 10 males and 15 females ) their age ranged between ( 18 and 70 years) who underwent spinal surgery with pedicle screw fixation for different disorders of

Enshrine the Principle of the Common Heritage of Humanity Within the Framework of International Law

The international community began to realize, following the discovery of  vast wealth in areas that fall outside the territorial limits of states sovereignty, that the huge difference in scientific and technological development between developed and developing countries may give developed countries the opportunity to exploit these wealth, and this, in turn, will lead to a widening gap between countries, developed and developing countries, and the consolidation of the principle of inequality due to the lack of third world countries with the capabilities that allow them to participate in the exploitation of these wealth, and when these concerns came to the fore in the United Nations General Assembly in 1967, Ambassador Arvid Bardo, th

Proposing a General Formula for Evaluating the Parametric Cost Using MLR Method

This research takes up address the practical side by taking case studies for construction projects that include the various Iraqi governorates, as it includes conducting a field survey to identify the impact of parametric costs on construction projects and compare them with what was reached during the analysis and the extent of their validity and accuracy, as well as adopting the approach of personal interviews to know the reality of the state of construction projects. The results showed, after comparing field data and its measurement in construction projects for the sectors (public and private), the correlation between the expected and actual cost change was (97.8%), and this means that the data can be adopted in the re

Minimizing the Principle Stresses of Powerhoused Rock-Fill Dams Using Control Turbine Running Units: Application of Finite Element Method

This study focuses on improving the safety of embankment dams by considering the effects of vibration due to powerhouse operation on the dam body. The study contains two main parts. In the first part, ANSYS-CFX is used to create the three-dimensional (3D) Finite Volume (FV) model of one vertical Francis turbine unit. The 3D model is run by considering various reservoir conditions and the dimensions of units. The Re-Normalization Group (RNG) k-ε turbulence model is employed, and the physical properties of water and the flow characteristics are defined in the turbine model. In the second phases, a 3D finite element (FE) numerical model for a rock-fill dam is created by using ANSYS®, considering the dam connection with its powerhouse
