In spatial databases, traditional approach is to build separate indexing structures for spatial and non-spatial attributes. This article introduces a new coupled approach that combines a 3D spatial primary index and a fuzzy non-spatial secondary index. Based on tests with several types of queries on a meteorological data set, it is shown that our coupled structure reduces the number of iterations and the time consumed for querying compared with the traditional uncoupled one.

Access structures for fuzzy spatial queries Sozer, A; Yazıcı, Adnan (2002-06-29) Spatial data are complex and have spatial components and uncertain properties. It is important to develop effective spatial and aspatial indexing techniques to facilitate spatial and/or aspatial querying for databases that deal with spatial data. In this study we discuss a number of spatial index structures, such as Multi-level grid file (MLGF), R-tree, and R*-tree, for fuzzy spatial and/or aspatial queries.
APPROXIMATION OF BOUNDS ON MIXED-LEVEL ORTHOGONAL ARRAYS Sezer, Ali Devin; Özbudak, Ferruh (2011-06-01) Mixed-level orthogonal arrays are basic structures in experimental design. We develop three algorithms that compute Rao- and Gilbert-Varshamov-type bounds for mixed-level orthogonal arrays. The computational complexity of the terms involved in the original combinatorial representations of these bounds can grow fast as the parameters of the arrays increase and this justifies the construction of these algorithms. The first is a recursive algorithm that computes the bounds exactly, the second is based on an as...
Implementation of x-tree with 3d spatial index and fuzzy secondary index Keskin, Sinan; Yazıcı, Adnan; Oğuztüzün, Mehmet Halit S.; Department of Computer Engineering (2010) Multidimensional datasets are getting more extensively used in Geographic Information Systems (GIS) applications in recent years. Due to large volume of these datasets efficient querying becomes a significant problem. For this purpose, before creating index structure with these enormous datasets, choosing an efficient index structure is an urgent necessity. The aim of this thesis is to develop an efficient, flexible and extendible index structure which comprises 3D spatial data in primary index and fuzzy at...
Comparison of multidimensional data access methods for feature-based image retrieval Arslan, Serdar; Saçan, Ahmet; Açar, Esra; Toroslu, İsmail Hakkı; Yazıcı, Adnan (2010-11-18) Within the scope of information retrieval, efficient similarity search in large document or multimedia collections is a critical task. In this paper, we present a rigorous comparison of three different approaches to the image retrieval problem, including cluster-based indexing, distance-based indexing, and multidimensional scaling methods. The time and accuracy tradeoffs for each of these methods are demonstrated on a large Corel image database. Similarity of images is obtained via a featurebased similarity...
Shape recognition with generalized beam angle statistics Tola, OO; Arica, N; Yarman Vural, Fatoş Tunay (2004-04-30) In this study, we develop a new shape descriptor and matching algorithm in order to find a given template shape in an edge detected image without performing boundary extraction. The shape descriptor based on Generalized Beam Angle Statistics (GBAS) defines the angles between the lines connecting each boundary point with the rest of the points, as random variable. Then, it assigns a feature vector to each point using the moments of beam angles. The proposed matching algorithm performs shape recognition by ma...
