A Pore Scale Flow Simulation of Reconstructed Model Based on the Micro Seepage Experiment

open access: yesGeofluids, 2017
Researches on microscopic seepage mechanism and fine description of reservoir pore structure play an important role in effective development of low and ultralow permeability reservoir. The typical micro pore structure model was established by two ways of

The Moab Design for Digital Object Versioning

open access: yesCode4Lib Journal, 2013
The Stanford Digital Repository has adopted the "Moab" design for versioned archiving of digital objects--a locally developed approach that optimizes data transfer, storage, and replication while providing efficient single file retrieval or full object ...

A New Adaptive Coding Selection Method for Distributed Storage Systems

open access: yesIEEE Access, 2018
Erasure codes, such as Reed-Solomon (RS) codes and local reconstruction codes (LRCs), are being increasingly adopted in distributed storage systems since they offer lower redundancy than data replication.

Reconstructing Geometric Models from the Point Clouds of Buildings Based on a Transformer Network

open access: yesRemote Sensing
Geometric building models are essential in BIM technology. The reconstruction results using current methods are usually represented using mesh, which is limited to visualization purposes and hard to directly import into BIM or modeling software for ...

Some Multisecret-Sharing Schemes over Finite Fields

open access: yesMathematics, 2020
A secret sharing scheme is a method of assigning shares for a secret to some participants such that only some distinguished subsets of these subsets can recover the secret while other subsets cannot.

Reconstructing Historical Populations from Genealogical Data Files

open access: yes, 2015
Over the past two decades, a huge number of historical documents have been digitised and made available online. At the same time, numerous software options and websites have encouraged people to conduct research into their family trees, leading to a surge in the availability of genealogical data.

From Rational Number Reconstruction to Set Reconciliation and File Synchronization [PDF]

open access: yes, 2013
This work revisits set reconciliation, the problem of synchronizing two multisets of fixed-size values while minimizing transmission complexity. We propose a new number-theoretic reconciliation protocol called Divide and Factor D&F that achieves optimal asymptotic transmission complexity --- as do previously known alternative algorithms. We analyze the

A Secret Image Sharing Method Using Integer Wavelet Transform

open access: yesEURASIP Journal on Advances in Signal Processing, 2007
A new image sharing method, based on the reversible integer-to-integer (ITI) wavelet transform and Shamir's threshold scheme is presented, that provides highly compact shadows for real-time progressive transmission.

Automatic lane marking extraction from point cloud into polygon map layer

open access: yesEuropean Journal of Remote Sensing, 2019
Optimization of road networks is a common concern worldwide, primarily for safety purposes. Because the extent of these networks is substantial, automation of their inventory is highly desirable. This paper concentrates on the road inventory process that
