An open-loop technique for angle determination from position encoders
(
IEEE
, 2008 , Conference Paper)
The paper presents a novel technique for the determination of the angle from low-frequency quadrature cosinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ...
Numerical bifurcation of predator-prey fractional differential equations with a constant rate harvesting
(
IOP Publishing
, 2008 , Article)
In this article saddle and Hopf bifurcation points of predator-prey fractional differential equations system with a constant rate harvesting are investigated. The numerical results based on Grunwald-Letnikov discretization ...
A New One-Step Iterative Process for Common Fixed Points in Banach Spaces
(
Hindawi Publishing Corporation
, 2008 , Article)
We introduce a new one-step iterative process and use it to approximate the common fixed points of two asymptotically nonexpansive mappings through some weak and strong convergence theorems. Our process is computationally ...
Modeling of the exhaust box assembly workshop using neural networks
(
IEEE
, 2008 , Conference Paper)
The paper investigates the use of artificial neural networks in modeling and control of manufacturing systems. This approach models the various elements of a manufacturing system by the form of neural networks. The modeling ...
Geology and petrology of the Hormuz dolomite, Infra-Cambrian: Implications for the formation of the salt-cored Halul and Shraouh islands, Offshore, State of Qatar
(
Elsevier Ltd
, 2008 , Article)
Geological investigations of the Halul and the Shraouh islands, offshore Qatar, indicate that most of their calcareous rocks, which display abundant stromatolitic bedding, belong to the Infra-Cambrian Hormuz Series. ...
Isolation and characterization of extracellular bioflocculants produced by bacteria isolated from Qatari ecosystems
(
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 ...
Hazards influencing coastal plains management along the Eastern stretch of the Gulf of Suez, Using remote sensing and GIS
(
IEEE
, 2008 , Conference Paper)
This research aims at to assess the impact of natural hazards on the human activities and development planning held along the eastern coastal stretch of the Gulf of Suez. Change detection technique was used in combined ...
Analysis of particulate behavior in porous media
(
Shanghai University Press
, 2008 , Article)
In this work, we analyze the behavior of the particle phase in the flow of a particle-laden mixture through a porous medium. An attempt is made to model the diffusion and dispersion processes, and to quantify the deviation ...
Voltage stability evaluation of real power transmission system using singular value decomposition technique
(
IEEE
, 2008 , Conference Paper)
Voltage stability is an important factor that needs to be taken into consideration during the planning and operation of power systems in order to avoid voltage collapse and subsequently partial or full system blackout. ...
Mobile-phone users’ attitudes towards’ mobile commerce & services in the Gulf Cooperation Council countries: Case study
(
IEEE
, 2008 , Conference Paper)
As the number of mobile phone users is growing, purchasing products and services using mobile phones and other mobile devices are also increasing. The purpose of this study was to provide the status of mobile-commerce in ...
