A semantic approach for document clustering
(
Academy Publisher
, 2009 , Article)
Conventional document mining systems mainly use the presence or absence of keywords to mine texts. However, simple word counting and frequency distributions of term appearances do not capture the meaning behind the words, ...
Quality assurance considerations in chemical analysis
(
John Wiley & Sons, Ltd.
, 2009 , Article)
Quality Assurance (QA) for an analytical laboratory is an essential tool to ensure good comparability of data. In order to achieve this purpose, processes are monitored and performance problems are systematically solved. ...
Cesarean section deliveries in the occupied Palestinian territory (oPt): An analysis of the 2006 Palestinian Family Health Survey
(
Elsevier
, 2009 , Article)
Objective
Against the backdrop of a rise in cesarean section deliveries from 6.0% in 1996 to 14.8% in 2006, the objective of this study was to investigate socio-demographic, clinical and service-related factors associated ...
Markedly improved CO2 capture efficiency and stability of gallium substituted hydrotalcites at elevated temperatures
(
American Chemical Society
, 2009 , Article)
Potassium carbonate promoted, Ga3+ substituted hydrotalcites reported here exhibit very high, selective and reversible CO2 capture from an exhaust gas mixture. The 10% Ga3+ substitution improved the CO2 capture from 0.3 ...
Dynamic risk assessment using failure assessment and Bayesian theory
(
Elsevier Ltd
, 2009 , Article)
To ensure the safety of a process system, engineers use different methods to identify the potential hazards that may cause severe consequences. One of the most popular methods used is quantitative risk assessment (QRA) ...
Efficient visual mixture design of experiments using property clustering techniques
(2009 , Article)
Mixture design is a design of experiments (DOE) tool used to determine the combination of chemical constitutents that deliver a desired response (or property) using a minimum number of experimental runs. While the approach ...
Minimum cycle bases for direct products of K2 with complete graphs
(
University of Queensland Press
, 2009 , Article)
We construct a minimum cycle basis for the direct product K2 x Kp of two complete graphs where p > 2. For p > 3, these bases consists only of squares. This completes the work of R. Hammack, who treated the case Kp x ...
On certain rough integral operators and extrapolation
(
Victoria university
, 2009 , Article)
In this paper, we obtain sharp Lp estimates of two classes of maximal operators related to rough singular integrals and Marcinkiewicz integrals. These estimates will be used to obtain similar estimates for the related ...
On rough maximal operators and Marcinkiewicz integrals along submanifolds
(2009 , Article)
We investigate the LP boundedness for a class of parametric Marcinkiewicz integral operators associated to submanifolds and a class of related maximal operators under the L(log L)α(Sn-1) condition on the kernel functions. ...
The Gulf: A young sea in decline
(
Elsevier Ltd
, 2009 , Article)
This review examines the substantial changes that have taken place in marine habitats and resources of the Gulf over the past decade. The habitats are especially interesting because of the naturally high levels of temperature ...
