Öğe International Journal of Engineering Technologies (IJET) Vol. 2, Issue 1, March 2016(İstanbul Gelişim Üniversitesi Yayınları / Istanbul Gelisim University Press, 2016) Çolak, İlhamiDear Colleagues, On behalf of the editorial board of International Journal of Engineering Technologies (IJET), I would like to share our happiness to publish the fifth issue of IJET. My special thanks are for members of editorial board, editorial team, referees, authors and other technical staff. Please find the fifth issue of International Journal of Engineering Technologies at http://dergipark.ulakbim.gov.tr/ijet. We invite you to review the Table of Contents by visiting our web site and review articles and items of interest. IJET will continue to publish high level scientific research papers in the field of Engineering Technologies as an international peerreviewed scientific and academic journal of Istanbul Gelisim University. Thanks for your continuing interest in our work, Professor ILHAMI COLAK Istanbul Gelisim University icolak@gelisim.edu.tr http://dergipark.ulakbim.gov.tr/ijet Printed ISSN: 2149-0104 e-ISSN: 2149-5262Öğe Planning and Design Principles of Transmission Line in Water Supply Project(İstanbul Gelişim Üniversitesi Yayınları / Istanbul Gelisim University Press, 2016-03-23) Gülbahar, NecatiWater is an essential substance for human life and living things. It is not substance for the life, but also energy input for agricultural and industrial production. In addition to, it is needed for human daily activities and environment. Water is taken to a place where people need by with transmission lines in water supply project. A transmission line is designed according to requirements, topographic conditions, engineering principles and economic criteria. Transmission lines are large scale projects which planned and projected by public organizations which are DSI, Provincial Bank and Municipalities. Although they are competent and experienced; some problems have been observed in water supply projects such as; lack of future plan, expropriation problem, improper pumping station, incapacity, inefficiency, pollution, poor quality, necessity, inadequate itineraries, too long lines. To avoid these problems, first future development plan for cities should be made and carried out without compromising. Next, the detail study should be carried out for each project from engineering, environmental and economic aspects. In this paper, these issues were examined and discussed to take attention to some important points in planning and designing of transmission line for the applicationÖğe Driving Shaft Fatigue Life Determination According to Turkish Mission Profiles(İstanbul Gelişim Üniversitesi Yayınları / Istanbul Gelisim University Press, 2016-03-23) Şener, Arif ŞenolIn this study, a questionnaire was used to determine the average customer usage of the light commercial vehicles in Turkey. Approximately on 50 road routes and on rough roads in Turkey, the fatigue characteristics of the road profiles were measured by a many sensors equipped on LCV (Light Commercial vehicle).This article focuses on defining the general load spectrum of Turkey roads belong to the driving shaft. Rain-flow statistical counting method was applied driving shaft’s signals in order to make fatigue comparisons meaningfully and other application. Fatigue analysis of the driving shaft according to MP (Turkish mission profiles) were calculated by using FEA (Finite Element Analysis) and verified by the Palmgren-Miner rule.Öğe A Comparison Study of Some Flood Estimation Methods in terms of Design of Water Structures(İstanbul Gelişim Üniversitesi Yayınları / Istanbul Gelisim University Press, 2016-03-23) Gülbahar, NecatiFlood is a natural disaster that caused the death of many people, environmental destruction and economical loses. Therefore, it is must be taken under control and prevent damage to the people and environment. Particularly, cities and villages have been often faced with floods that result from engineering and planning errors in Turkey. As a conventional approach, some certain calculations methods have been developed in order to estimate flood discharge, velocity, depth and recurrence in this regard. Some of them are widely used for the flood estimation such as; unit hydrograph, stochastic and statistical, Rational, MacMath, Kirpich, Mockus, SCS, Snyder and Degree-Day methods. Because, every method has some significant limiting conditions, each one gives different results for same place. According to recent researches, selection of the proper method is very important to reach more accurate results, but the best one is measuring. Therefore, a suitable method to meteorological, hydrologic, topographic conditions of a basin should be selected for the successful application. In this paper, some common conventional methods were discussed and evaluated for the aim of performing better results.Öğe H2-Anion Interactions and Energy Calculations for Imidazolium-based Ionic Liquids as Hydrogen Storage Materials(İstanbul Gelişim Üniversitesi Yayınları / Istanbul Gelisim University Press, 2016-03-23) Karakaya, Mustafa; Ucun, FatihThe aims of this study are to explore the molecular hydrogen-anion interactions and assess the energy calculations in imidazolium-based compounds. The stable modes were structurally discussed after the achieving optimizations by density functional theory. It is concluded that the interaction energies were very weak against the strong interaction lengths. The impacts of the loaded molecular hydrogen to the imidazolium-based structure were discussed by the frontier molecular orbital analysis. While the amounts of H2 involved to the interaction increased, the changes in the energy gap were calculated. The bonding interactions on the cation–anion and molecular nH2–anion were compared.
