An efficient technique for finding the eigenvalues of fourth-order Sturm–Liouville problems
(
Elsevier
, 2009 , Article)
In this paper, we will develop a numerical technique for finding the eigenvalues of fourth-order non-singular Sturm–Liouville problems. We used the variational iteration methods as a basis for this technique. Numerical ...

(
POLISH SOCIETY OF MICROBIOLOGISTS
, 2008 , Article)
Compared with conventional synthetic flocculants, bioflocculants has special advantages such as safety, strong effect, biodegradable and harmlessness to humans and the environment, so they may potentially be applied in ...
The effects of ion bombardment of ultra-high molecular weight polyethylene
(
Elsevier
, 2006 , Article)
Ion bombardment is a suitable tool to improve tribological properties of polymers. In this study UHMWPE samples were bombarded with 130keV He ions to the fluences ranging from 1×1014 to 2×1016cm−2. RBS and NRA techniques ...
Large sample and bootstrap intervals for the gamma scale parameter based on grouped data
(
Wayne State University
, 2006 , Article)
Interval estimation of the scale parameter of the gamma distribution using grouped data is considered in this article. Exact intervals do not exist and approximate intervals are needed Recently, Chen and Mi (2001) proposed ...
On the Lp boundedness of rough parametric Marcinkiewicz functions
(
Victoria University
, 2007 , Article)
In this paper, we study the Lp boundedness of a class of parametric Marcinkiewicz integral operators with rough kernels in L(log + L)(Sn-1). Our result in this paper solves an open problem left by the authors of ([6]).
