Hybrid intelligent system for disease diagnosis based on artificial neural networks, fuzzy logic, and genetic algorithms
(2011 , Conference Paper)
Disease diagnosis often involves acquiring medical images using devices such as MRI, CT scan, x-ray, or mammograms of patients' organs. Though many medical diagnostic applications have been proposed; finding subtle cancerous ...
Flywheel energy storage system based on boost DC-AC converter
(
http://dx.doi.org/10.1049/cp.2011.0194
, 2011 , Conference Paper)
An additional DC-DC boost converter is used in conventional configuration of Flywheel Energy Storage System (FESS) to regulate the output voltage during flywheel low speeds. This paper presents a new FESS based on the boost ...
Study on hydroxylammonium-based ionic liquids. I. Characterization
(
American Chemical Society
, 2011 , Article)
Two selected ammonium-based ionic liquids, 2-hydroxyethyltrimethylammonium l-(+)-lactate and tris(2-hydroxyethyl)methylammonium methylsulfate, were fully characterized. The most relevant thermophysical properties of pure ...
Time-frequency analysis of heart rate variability in neonatal piglets exposed to hypoxia
(2011 , Conference Paper)
To determine whether the sympathetic nervous system plays any role in the inter-individual variation of cardiovascular response to hypoxia in newborns, neonatal heart rate variability (HRV) analysis was used to assess ...
Two way opportunistic MAC protocol for Ad Hoc networks
(
IEEE
, 2011 , Conference Paper)
In this paper, network coding is introduced in relay based MAC protocols for bidirectional traffic to evaluate the performance in terms of throughput and energy. The idea of proposed scheme is to use high data rate nodes ...
Managing uncertain inventory in supply chain with neural network and radio frequency identification (RFID)
(
IGI Global
, 2011 , Book chapter)
Demand uncertainty leads to fluctuations in inventory position at each echelon of a supply chain causing bullwhip effect, which can lead to significant cost and loss of efficiency and waste of resources. One of the aspects ...
Advanced experimental setup for the reliability characterization of radio-acoustic sensors in water pipes
(
IEEE
, 2011 , Conference Paper)
The paper presents the design and construction of a test bench for the analysis and certification of radio-acoustic sensors inside conduits filled with liquids. It is a brand new test-set that integrates the capability to ...
Experimental photovoltaic power supply based on flying capacitors multilevel inverter
(
IEEE
, 2011 , Conference Paper)
Nowadays, a great deal of research is being carried out to utilize the solar energy effectively through power electronics converters (conditioners) to meet the increasing demand for load. In this paper, a weighted Real ...
Teacher perceptions of professional development in the context of national educational reform: the case of Qatar*
(
Blackwell Publishing Ltd
, 2011 , Article)
In light of nationally mandated educational changes in Qatar, this study investigates in-service teachers' perceptions of professional development (PD). The aims are to identify challenges facing teachers' PD. The respondents ...
Model for oscillations in the guidance of ions through insulating nanocapillaries
(
IOP Publishing
, 2011 , Conference Paper)
The pre-equilibrium period of the ion guiding through insulating nanocapillaries is characterized by the production of temporary charge patches inside the capillaries. The dynamics of the charge patch creation is revealed ...
