Analytical approach to the Darcy–Lapwood–Brinkman equation
(
Elsevier
, 2007 , Article)
Three exact solutions are obtained for flow through porous media, as governed by the Darcy–Lapwood–Brinkman model, for a given vorticity distribution. The resulting flow fields are identified as reversing flows; stagnation ...
A novel amplitude-to-phase converter for sine/cosine position transducers
(
Taylor and Francis Group
, 2007 , Article)
Resolvers and various other types of sine/cosine encoders are used for both angular and linear position sensing. These devices provide analogue signals in the form of the sine and the cosine of an angle related to the ...

Solving systems of fractional differential equations using differential transform method
(
Elsevier B.V.
, 2007 , Article)
This paper presents approximate analytical solutions for systems of fractional differential equations using the differential transform method. The fractional derivatives are described in the Caputo sense. The application ...
The multistage homotopy-perturbation method: A powerful scheme for handling the Lorenz system
(
Elsevier
, 2007 , Article)
In this paper, a new reliable algorithm based on an adaptation of the standard homotopy-perturbation method (HPM) is presented. The HPM is treated as an algorithm in a sequence of intervals (i.e. time step) for finding ...
Weighted estimates for rough parametric Marcinkiewicz integrals
(
Korean Mathematical Society
, 2007 , Article)
We establish a weighted norm inequality for a class of rough parametric Marcinkiewicz integral operators . As an application of this inequality, we obtain weighted inequalities for a class of parametric Marcinkiewicz ...
A rich learning lesson using the Poisson distribution
(
Elsevier B.V.
, 2007 , Article)
In this note, we explore the rich information about inference that the Poisson distribution has. The source of this information is mainly the fact that the mean and variance of this distribution are equal.
A simple method for finding empirical likelihood type intervals for the ROC curve
(
Wayne State University
, 2007 , Article)
Interval estimation of the ROC curve is considered using the empirical likelihood techniques. Suggested is a procedure that is very simple computationally and avoids the constrained optimization problems usually faced with ...
