Indexing Fuzzy Spatiotemporal Data for Efficient Querying: A Meteorological Application
Sozer, Aziz; Yazıcı, Adnan; Oğuztüzün, Mehmet Halit S. (2015-10-01)
Spatiotemporal data, in particular fuzzy and complex spatial objects representing geographic entities and relations, is a topic of great importance in geographic information systems and environmental data management systems. For database researchers, modeling and designing a database of fuzzy spatiotemporal data and querying such a database efficiently have been challenging issues due to complex spatial features and uncertainty involved. This paper presents an integrated approach to modeling, indexing, and ...
Exploiting Index Pruning Methods for Clustering XML Collections
Altıngövde, İsmail Sengör; Ulusoy, Ozgur (2010-01-01)
In this paper, we first employ the well known Cover-Coefficient Based Clustering Methodology (C3 M) for clustering XML documents. Next, we apply index pruning techniques from the literature to reduce the size of the document vectors. Our experiments show that for certain cases, it is possible to prune up to 70% of the collection (or, more specifically, underlying document vectors) and still generate a clustering structure that yields the same quality with that of the original collection, in terms of a set o...
Comparison of 2D and 3D finite element models of tunnel advance in soft ground: a case study on Bolu tunnels
Üçer, Serkan; Bakır, Bahadır Sadık; Department of Civil Engineering (2006)
The Bolu Tunnels lie along Trans European Motorway (TEM) which is connecting Eastern Europe with the Middle East. The tunnels are approximately 3.0 km long, 40 m apart and have excavated cross sections more than 200 m2. In construction, New Austrian Tunneling Method (NATM) was used in soft ground. Due to the challenging ground conditions, many problems have been encountered during tunnelling. To solve these problems special construction techniques were adapted. To simulate and demonstrate the effectiveness ...
Stability analysis, displacement monitoring and justification of the critical sections of the Konak tunnel
Yertutanol, Kadir; Akgün, Haluk; Department of Geological Engineering (2015)
The main focus of this research is numerical analysis and preliminary support design for the critical sections of the twin tube Konak Tunnel that was constructed in a highly populated area in Konak, İzmir. The displacements of the tunnel were monitored and justified by comparing with the results of the numerical analyses. The stability of the tunnel exit portal and associated slopes, which is one of the most challenging sections of the project, was analyzed as well. In study area, volcanics, pyroclastics an...
Learning-based methods for multi-modal and multi-spectral data
Özkan, Savaş; Akar, Gözde; Department of Electrical and Electronics Engineering (2020-10-15)
Data-driven solutions have become essential parts of our daily lives. These solutions generally consume a large amount of supervised data. Additionally, a large-body of learnable parameters must be trained to be able to reach the level of human knowledge accurately. However, these dependencies can be overcome by making full use of domain-specific features via specialized learning structures. This thesis addresses unsupervised and multimodal data by utilizing different sensor types and application doma...
