Recently, owing to incredible development in Geographic Information Systems (GIS) and software fields, besides effectively using the network and topology instruments, great advances have been made in the field of hydrologic coding through robust interaction among multidisciplinary sciences. If all hydrological properties can be combined in a network that has its own sui generis situation and topological properties, meaningful and holistic analyses can be formed more easily. Additionally, GIS topology is an essential phenomenon for performing different types of network analysis, therefore the topological network model manages spatial relationships by illustrating shapes as the graph of topological instruments (node, edge, etc.) via computer geometry. In this study, the Pfafstetter method, which stands out with its topological feature and the most common hydrological codification systems all over the world, was coded. It was written in Object-Oriented Program (OOP) language and formatted as a binary tree data structure. The proposed code was applied to three different river basins namely Çakıt Basin and Yeşilırmak Basin which are located in Turkey, and Thames River Basin which is located in the UK. It is observed that successful results were obtained.

Development of GIS-based national hydrography dataset, sub-basin boundaries, and water quality/quantity data analysis system for Turkey Girgin, Serkan; Usul, Nurünnisa; Akyürek, Zuhal; Department of Geodetic and Geographical Information Technologies (2003) Computerized data visualization and analysis tools, especially Geographic Information Systems (GIS), constitute an important part of today̕s water resources development and management studies. In order to obtain satisfactory results from such tools, accurate and comprehensive hydrography datasets are needed that include both spatial and hydrologic information on surface water resources and watersheds. If present, such datasets may support many applications, such as hydrologic and environmental modeling, imp...
Weighted multi-visibility analysis on directional paths Şeker, Çağıl; Toprak, Vedat; Department of Geodetic and Geographical Information Technologies (2010) Visibility analysis is an important GIS tool that is used in a diverse array of disciplines ranging from earth sciences to telecommunications. Multi-visibility, as a cumulative type of visibility, combines many point-to-point results into a multi-value array. Points, lines, or areas can be used as sources or targets; and the combined values can be calculated in both ways. Through multi-visibility, a special 2.5D visibility value surface can be constructed over a digital elevation model. The effectiveness of...
A deep learning approach for the transonic flow field predictions around airfoils Duru, Cihat; Alemdar, Hande; Baran, Özgür Uğraş (2022-01-01) Learning from data offers new opportunities for developing computational methods in research fields, such as fluid dynamics, which constantly accumulate a large amount of data. This study presents a deep learning approach for the transonic flow field predictions around airfoils. The physics of transonic flow is integrated into the neural network model by utilizing Reynolds-averaged Navier–Stokes (RANS) simulations. A detailed investigation on the performance of the model is made both qualitatively and quant...
A longest path problem for evaluating the worst case packet delay of switched ethernet Schmidt, Klaus Verner; Schmidt, Şenan Ece (2010-07-09) In the recent years, the use of real-time Ethernet protocols becomes more and more relevant for time-critical networked industrial applications. In this context, this paper presents a method to compute the worst-case packet delays on switched Ethernet. Based on an evaluation of the packet delays at each switch port and the network topology, we construct a weighted directed graph that allows to find the worst-case end-to-end packet delay by solving a conventional longest-path problem.
A Holistic Work System Framework (HWSF) Development Using Systems Thinking Ozalp, Egemen; Baykal, Buyurman (2014-07-31) Technology and Engineering Management Activities induced the awareness of Work Systems (WS) in Business Conduction. During WS activities and decisions settings, typically technical perspectives are espoused heavily. Although, remedies of this kind require holistic approaches, such approaches are not very common. One of the main reasons for this inadequacy is the lack of conforming guidance. In this work, the aim is to create a framework as guidance for WS activities. The Holistic Work System Framework (HWSF...
