Bulk-loading and bulk-insertion algorithms for xBR +-trees in Solid State Drives
(2019)Spatial indexes are important in spatial databases for efficient execution of queries involving spatial constraints. The xBR +-tree is a balanced, disk-resident, Quadtree-based index for point data, which is very efficient ... -
Bulk-loading xBR+-trees
(2016)Spatial indexes are important in spatial databases for efficient execution of queries involving spatial constraints. The xBR+-tree is a balanced disk-resident quadtree-based index structure for point data, which is very ... -
Contribution to the design methodologies of piled raft foundations under combined loadings
(2016)Although simplified design methods for piled raft foundations have been proposed to allow for the group effect and soil-pile-raft interaction, most of them are concentrated on one type of loading, rendering the applicability ... -
Dependence of friction coefficient on the resolution of asperities in metallic rough surfaces under cyclic loading
(2017)In this paper the friction mechanism that is developed between metallic rough interfaces with irregularities of different scales, submitted to cyclic loading is studied. The main purpose of the paper is to investigate how ... -
An efficient algorithm for bulk-loading xBR+-trees
(2018)A major part of the interface to a database is made up of the queries that can be addressed to this database and answered (processed) in an efficient way, contributing to the quality of the developed software. Efficiently ... -
Fatigue failure of buckled pipelines
(2004)Quite often, steel buried pipelines exhibit local buckles due to imposed deformations, which may cause failure because of fatigue from repeated loading. When such buckles are detected in a steel pipeline, a decision must ... -
Fatigue reliability predictions in vibrating structures under uncertainty
(2008)This work addresses the problem of predicting the reliability due to fatigue of MDOF structures subjected to uncertain random loading. Uncertainties in loading characteristics as well as in structural and degradation models ... -
Finite element analysis of cyclically-loaded steel pipes during deep water reeling installation
(2015)Thick-walled steel pipes during their installation in deepwater are subjected to combined loading of external pressure and bending, which may trigger structural instability due to excessive pipe ovalization with catastrophic ... -
Numerical Evaluation of Pile Response Under Combined Lateral and Axial Loading
(2018)Piled foundations are frequently subjected to simultaneous axial and lateral loadings. However, the interaction effects of the one loading on the other are, in most cases, disregarded for the sake of simplicity. With the ... -
Numerical modelling of steel pipelines subjected to severe monotonic and cyclic straining
(2014)Offshore and onshore pipelines may experience extreme loading conditions during their installation and operation, both of monotonic and cyclic nature. Loading actions such as pipeline lateral displacements, tensioning, or ... -
On the adequacy of existing foundation schemes for offshore wind turbines subjected to extreme loading
(2017)Dictated by the world's escalating energy demands, offshore infrastructure is moving beyond the immediate continental shelf into deeper waters. Although the monopile solution has proven its reliability for many years, its ... -
Reduced service life of concrete sleepers due to inadequate design
(2010)During the 1980's, the twin-block concrete sleepers/ties -designed and laid in railway lines with maximum operational speed of 200 km/h in France- which were laid on a track with maximum operational speed of 140 km/h in ... -
Response of pile groups in clays under lateral loading based on 3-D numerical experiments
(2010)The response of laterally loaded pile foundations may be significantly important in the design of structures for such loads. Although simplified numerical methods are reliable for evaluating the response of a single pile ... -
Simulation of industrial elbow response under strong cyclic loading
(2011)Elbow components are widely used in industrial facilities as parts of piping/tubing systems. Their performance under severe loading conditions may be critical for the structural integrity of an industrial facility In the ... -
