Towards model-based management of database fragmentation
(
USENIX Association
, 2013 , Conference Paper)
The performance of a database can significantly deteriorate due to the fragmentation of data/index files. Manual database defragmentation and performance optimization remain time consuming and even infeasible as it requires ...
An accurate finite volume method using fourth order Adams scheme on triangular grids for the Saint-Venant System
(2013 , Conference Paper)
In this study, a new finite volume method is developed for shallow water equations on a rotating
frame. Most upwind methods, which perform well for gravity waves, lead to large oscillations and/or
numerical damping for ...
Numerical simulation of thermal buoyant wall jets
(2013 , Conference Paper)
The main focus of this study is on the near field flow and mixing characteristics of the thermal
wall jets. A numerical study of the buoyant wall jets discharged from submerged outfalls from cooling
systems of power ...
EFFECT OF COMPATIBILIZER ON MECHANICAL AND PHYSICAL PROPERTIES OF GREEN COMPOSITES BASED ON HIGH DENSITY POLYETHYLENE AND DATE PALM FIBER
(
DEStech Publications
, 2013 , Conference Paper)
Date palm leaves and wood are common wastes in the middle east. These natural fibers can be used as additives for polymers to develop new desired properties; they also have important economic and environmental advantages. ...
Ion impact induced ionization/fragmentation dynamics of rare gas Dimers
(
IOP Publishing
, 2013 , Conference Paper)
We have measured the ionization and fragmentation of Helium, Neon and Argon Dimers induced by ion impact and observed two different pathways, the sequential ionization on each atom and the interatomic Cou-lombic decay. © ...
Three Dimensional Computational Study for Spiral Dry Gas Seal with Constant Groove Depth and Different Tapered Grooves
(
Elsevier Ltd
, 2013 , Conference Paper)
The three dimensional simulation for dry gas seal with constant depth spiral grooves and with different taper grooves is done using ANSYS FLUENT CFD code. Grid independence study and code validation are done with experimental ...
Centrifugal Compressor Spiral Dry Gas Seal Simulation Working at Reverse Rotation
(
Elsevier Ltd
, 2013 , Conference Paper)
Unidirectional dry gas seal may experiences reverse rotation when equipped in a centrifugal compressor. This paper describes how the reverse rotation effects on the spiral unidirectional dry gas seal performance and pressure ...
ConMR: Concurrent MapReduce programming model for large scale shared-Data applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
The rapid growth of large-data processing has brought in the MapReduce programming model as a widely accepted solution. However, MapReduce limits itself to a onemap- To-one-reduce framework. Meanwhile, it lacks built-in ...
Using safety constraint for transactional dataset anonymization
(
Springer
, 2013 , Conference Paper)
In this paper, we address privacy breaches in transactional data where individuals have multiple tuples in a dataset. We provide a safe grouping principle to ensure that correlated values are grouped together in unique ...
Secure and private outsourcing of shape-based feature extraction
(
Springer
, 2013 , Conference Paper)
There has been much recent work on secure storage outsourcing, where an organization wants to store its data at untrusted remote cloud servers in an encrypted form, such that its own employees can query the encrypted data ...
