Standard numerical schemes for coupled parallel flow over porous layers
(
Elsevier
, 2007 , Article)
In this work, we develop finite difference schemes of various orders of accuracy that are suitable for the simulation of flow through and over porous layers. The flow through the porous layer is assumed to be governed by ...
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 ...
The implementation of world class manufacturing techniques in Egyptian manufacturing firms: An empirical study
(
Emerald Group Publishing Limited
, 2007 , Article)
Purpose - The purposes of this paper are to illustrate how the world class manufacturing (WCM) techniques which could be described as outperforming the industry's global best practices have been implemented in the Egyptian ...
The impact of organizational characteristics on AMT adoption: A study of Egyptian manufacturers
(
Emerald Group Publishing Limited
, 2007 , Article)
Purpose - This research seeks to empirically explore and examine the impact of organizational characteristics, i.e. firm size, type of production system, organizational design and type of ownership, on advanced manufacturing ...
Assessing the responsiveness of the Asthma Quality of Life Questionnaire with pharmaceutical care
(
Springer Netherlands
, 2007 , Article)
Objective: To assess the responsiveness of the Asthma Quality of Life Questionnaire (AQLQ) in the context of pharmaceutical care delivery New Zealand community pharmacy setting. Setting: Community pharmacy practices in ...
Sinc-based computations of eigenvalues of Dirac systems
(
Springer Netherlands
, 2007 , Article)
The celebrated classical sampling theorem is used to compute approximate values of the eigenvalues of Dirac systems with eigenvalue parameter in the boundary conditions. We deal with problems with an eigenparameter in one ...
