Efficient spatial designs using Hausdorff distances and Bayesian optimization
(Peer reviewed; Journal article, 2021)An iterative Bayesian optimization technique is presented to find spatial designs of data that carry much information. We use the decision theoretic notion of value of information as the design criterion. Gaussian process ... -
Efficient Spatial Search using Memory Resident R-trees
(Master thesis, 2017)This thesis investigates the performance of memory resident spatial search, focusing on the R-tree. The characteristics of modern computer architectures are first visited to understand how they have changed since the ... -
Efficient spatio-interval join
(Master thesis, 2018)This thesis studies existing techniques for both spatial join and interval join. Us- ing existing methods and algorithms for join operations two new algorithms for spatio-interval join is developed. Parallelization techniques ... -
Efficient split-step schemes for fluid–structure interaction involving incompressible generalised Newtonian flows
(Peer reviewed; Journal article, 2022)Blood flow, dam or ship construction and numerous other problems in biomedical and general engineering involve incompressible flows interacting with elastic structures. Such interactions heavily influence the deformation ... -
Efficient storage of heterogeneous geospatial data in spatial databases
(Journal article; Peer reviewed, 2019)The no-schema approach of NoSQL document stores is a tempting solution for importing heterogenous geospatial data to a spatial database. However, this approach means sacrificing the benefits of RDBMSes, such as existing ... -
Efficient Streaming and Compression of Hyperspectral Images
(Master thesis, 2018)As a part of the SmallSat project at NTNU, a satellite payload capable of capturing and processing of hyperspectral images is being developed. Several processing steps are performed on-board in the satellite, as well as ... -
Efficient technology implementation - A case study of factors influencing technology implementation in Statoil
(Master thesis, 2014)Almost every company faces situations where they need to implement technology. Even if a company develops technology in-house, the technology needs to be implemented and used in other units within the firm. Implementation ... -
Efficient Top-K Fuzzy Interactive Query Expansion While Formulating a Query: From a Performance Perspective
(Master thesis, 2013)Interactive query expansion and fuzzy search are two efficient techniques for assisting a user in an information retrieval process. Interactive query expansion helps the user refine a query by giving suggestions on how a ... -
Efficient top-k recently-frequent term querying over spatio-temporal textual streams
(Peer reviewed; Journal article, 2021)Massive amounts of data with spatio-temporal-textual information are being generated due to the proliferation of GPS-equipped mobile devices. Much of this data are social media posts, often used to share and spread personal ... -
Efficient Trajectory Clustering with Road Network Constraints Based on Spatiotemporal Buffering
(Peer reviewed; Journal article, 2023)The analysis of individuals’ movement behaviors is an important area of research in geographic information sciences, with broad applications in smart mobility and transportation systems. Recent advances in information and ... -
An efficient transient‐state algorithm for evaluation of leakage through defective cutoff walls
(Peer reviewed; Journal article, 2021)Artificial barriers are widely used to prevent leakages. However, due to construction errors during the wall installation, passages with small dimensions may occasionally penetrate through the barrier, undermining its ... -
