Çoklu akifer sistemlerinde beslenim ve boşalım mekanizmalarının çevresel izotoplar ve asal gazlar kullanılarak araştırılması

Experimental and numerical investigation of vortex formation at multiple horizontal intakes Yıldırım, Tuğçe; Göğüş, Mustafa; Köken, Mete; Department of Civil Engineering (2020-8) Although most of the equations given in the literature for critical submergence are for symmetrical single intakes; in practice approach flow conditions are not mainly symmetrical. In this study, formation of the vortices in asymmetrical approach flow conditions was investigated for a multiple water intake structure composed of a reservoir and several pipe systems. Different scenarios were tested when some of the intake units were in operation whereas some others were not. The geometrical and hydraulic...
Feasibility study of multiple hydropower project: case study of Baltacı stream, Trabzon, Turkey Aydın, Boran Ekin; Kentel Erdoğan, Elçin; Altınbilek, Doğan H.; Department of Civil Engineering (2010) High greenhouse gas emissions increased the importance of renewable energy resources. Hydropower is among the most widely used type of renewable energy. Oppositions to big hydropower projects with reservoirs increased the use of small hydropower plants. Development of a small hydropower project is a challenging engineering task. Different software’s are developed and used to make initial estimations of energy generation and initial costs of the project. RETScreen Clean Energy Analysis Software which can be ...
The effects of multiple representations-based instruction on seventh grade students' algebra performance, attitude towards mathematics, and representation preference. Çıkla Akkuş, Oylum; Çakıroğlu, Erdinç; Department of Secondary Science and Mathematics Education (2004) The purpose of this study was to investigate the effects of multiple representations-based instruction on seventh grade students̕ algebra performance, attitudes toward mathematics, and representation preference compared to the conventional teaching. Moreover, it was aimed to find out how students use multiple representations in algebraic situations and the reasons of preferring certain modes of representations. The study was conducted in four seventh grade classes from two public schools in Ankara in the 20...
Çoklu Ortam Telsiz Sensör Ağlarında Nesne Tanıma Ve Görüntü Sıkıştırma Algoritmalarının Geliştirilmesi. Coşar, Ahmet(2011-12-31) Kapsam: Kamera sensörleri kullanılarak alınan görüntüler "hareket tespiti" ve "nesne tanınması" işlevlerini gerçekleştirmek üzere algoritmalar geliştirilecektir. Yöntem: OPENCY ve PYMEDIA kütüphaneleri kullanılarak C, C++, Java ve Python dillerinden biriyle öncelikle hareket tespiti işlevi gerçekleştirilecektir. Daha sonra görüntü işleme yöntemleriyle nesne tanınması algoritmaları gerçekleştirilerek başarılarının tespit ve iyileştirilmesi sağlanacaktır. İlerlemeler: Yapılan iki "Term Project" çalışması ile...
Development of a dynamic maintenance algorithm with multiple scenarios: a case study for surface mining Ölmez Turan, Merv; Gölbaşı, Onur; Department of Mining Engineering (2019) Surface mining operations such as ore extraction and overburden stripping activities highly depend on machine performance. These machines’ operational plan aims to handle required amount of material within a specific period with the lowest maintenance cost and the highest availability. In order to achieve these objectives, the machines should be adapted to the production schedule properly. On this basis, maintenance policies play crucial roles in the sustainability of operations. A maintenance policy is bas...
