DZI: An air index for spatial queries in one-dimensional channels

VIP-Tree: An Effective Index for Indoor Spatial Queries

Due to the growing popularity of indoor location-based services, indoor data management has received significant research attention in the past few years. However, we observe that the existing indexing and query processing techniques for the indoor space do not fully exploit the properties of the indoor space. Consequently, they provide below par performance which makes them unsuitable for larg...

An ACO algorithm for one-dimensional cutting stock problem

The one-dimensional cutting stock problem, has so many applications in lots of industrial processes and during the past few years has attracted so many researchers’ attention all over the world. In this paper a meta-heuristic method based on ACO is presented to solve this problem. In this algorithm, based on designed probabilistic laws, artificial ants do select various cuts and then select the...

Spatial Cone Tree: An Index Structure for Correlation-based Similarity Queries on Spatial Time Series Data

An Analytical Solution for One-dimensional Horizontal Imbibition in a Cocurrent Flow

Cocurrent spontaneous imbibition (COCSI) of an aqueous phase into matrix blocks arising from capillary forces is an important mechanism for petroleum recovery from fractured petroleum reservoirs. In this work, the modeling of countercurrent imbibition is used to develop the appropriate scaling equations. Considering the imbibition process and the water and oil movement respectively as the wet p...

A Secure One-Roundtrip Index for Range Queries

We present the first one-roundtrip protocol for performing range, range-aggregate, and order-by-limit queries over encrypted data, that both provides semantic security and is efficient. We accomplish this task by chaining garbled circuits over a search tree, using branch-chained garbled circuits, as well as carefully designing garbled circuits. We then show how to build a database index that ca...
