Association rules for supporting hoarding in mobile computing environments
(IEEE, 2000)One of the features that a mobile computer should provide is disconnected operation which is performed by hoarding. The process of hoarding can be described as loading the data items needed in the future to the client cache ... -
Automatic detection of salient objects and spatial relations in videos for a video database system
(Elsevier BV, 2008-10)Multimedia databases have gained popularity due to rapidly growing quantities of multimedia data and the need to perform efficient indexing, retrieval and analysis of this data. One downside of multimedia databases is the ... -
Automatic performance evaluation of Web search engines
(Elsevier, 2004)Measuring the information retrieval effectiveness of World Wide Web search engines is costly because of human relevance judgments involved. However, both for business enterprises and people it is important to know the most ... -
Building user-defined runtime adaptation routines for stream processing applications
(VLDB Endowment, 2012)Stream processing applications are deployed as continuous queries that run from the time of their submission until their cancellation. This deployment mode limits developers who need their applications to perform runtime ... -
Context learning in Okapi
(1997)A user who makes repeated use of a retrieval system may be assumed to have a context which is common to successive uses (even if the immediate need differs). An IR system which could make use of this context may be better ... -
A data mining approach for location prediction in mobile environments
(Elsevier, 2005)Mobility prediction is one of the most essential issues that need to be explored for mobility management in mobile computing systems. In this paper, we propose a new algorithm for predicting the next inter-cell movement ... -
Effect of inverted index partitioning schemes on performance of query processing in parallel text retrieval systems
(Springer, 2006-11)Shared-nothing, parallel text retrieval systems require an inverted index, representing a document collection, to be partitioned among a number of processors. In general, the index can be partitioned based on either the ... -
Flame detection in video using hidden Markov models
(IEEE, 2005)This paper proposes a novel method to detect flames in video by processing the data generated by an ordinary camera monitoring a scene. In addition to ordinary motion and color clues, flame flicker process is also detected ... -
From a calculus to an execution environment for stream processing
(ACM, 2012)At one level, this paper is about River, a virtual execution environment for stream processing. Stream processing is a paradigm well-suited for many modern data processing systems that ingest high-volume data streams from ... -
From virtual to physical: Integration of chemical logic gates
(2011)Integration by parts: Advanced information processing at the molecular level requires integrated logic gates, which has to date been possible only virtually. Now, two independently working AND molecular logic gates are ... -
Hypergraph-theoretic partitioning models for parallel web crawling
(Springer, London, 2012)Parallel web crawling is an important technique employed by large-scale search engines for content acquisition. A commonly used inter-processor coordination scheme in parallel crawling systems is the link exchange scheme, ... -
IBM streams processing language: analyzing big data in motion
(I B M Corp., 2013-05-17)The IBM Streams Processing Language (SPL) is the programming language for IBM InfoSphere® Streams, a platform for analyzing Big Data in motion. By “Big Data in motion,” we mean continuous data streams at high data-transfer ... -
An inquiry into the learning-style and knowledge-building preferences of interior architecture students
(Elsevier, 2016-05)This study explores the learning-style and knowledge-building preferences of interior architecture students using Felder-Soloman's Index of Learning Styles. Considering the learning and knowledge-building skills of students ... -
Large-scale cluster-based retrieval experiments on Turkish texts
(ACM, 2007)We present cluster-based retrieval (CBR) experiments on the largest available Turkish document collection. Our experiments evaluate retrieval effectiveness and efficiency on both an automatically generated clustering ... -
Linear algebraic theory of partial coherence: discrete fields and measures of partial coherence
(SPIE, 2003-08)We present a linear algebraic theory of partial coherence which allows precise mathematical definitions of concepts such as coherence and incoherence. This not only provides new perspectives and insights, but also allows ... -
Location and curvature estimation of "spherical" targets using a flexible sonar configuration
(IEEE, 1996)A novel, flexible, three-dimensional (3-D) multi-sensor sonar system is employed to localize the center of a spherical target and estimate its radius of curvature. The interesting limiting cases for the problem under study ... -
Mean-shift tracking of moving objects using multi-dimensional histograms
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2004-04)In this paper, a moving object tracking algorithm for infrared image sequences is presented. The tracking algorithm is based on the mean-shift tracking method which is based on comparing the histograms of moving objects ...
