Image quality metrics based multifocus image fusion
(
IEEE
, 2011 , Conference Paper)
We describe an innovative methodology for block based multifocus
image fusion in the spatial domain. The main idea is
to use blind or no reference blur metrics for image fusion applications.
Two blur quality metrics ...
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 ...
Accelerometer-based fetal movement detection
(
IEEE
, 2011 , Conference Paper)
Monitoring fetal wellbeing is a compelling problem in modern obstetrics. Clinicians have become increasingly aware of the link between fetal activity (movement), well-being, and later developmental outcome. We have recently ...
Kalman filter-based time-varying cortical connectivity analysis of newborn EEG
(
IEEE
, 2011 , Conference Paper)
Multivariate Granger causality in the timefrequency
domain as a representation of time-varying cortical
connectivity in the brain has been investigated for the adult
case. This is, however, not the case in newborns as ...
Accurate and efficient implementation of the time–frequency matched filter
(
Institution of Engineering and Technology
, 2010 , Article)
The discrete time-frequency matched filter should replicate the continuoustime-frequency matched filter, but the methods differ. To avoid aliasing, thediscrete method transforms the real-valued signal to the complex-valued ...
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. ...
Fuzzy system applications for identification of weak buses in power systems
(
King Fahd University of Petroleum and Minerals
, 2002 , Article)
In this paper a simple new algorit hm for identifying the weak buses in a power system for voltage stability study is presented. The proposed algorithm is based on fuzzy set theory. Two membership functions, one for voltage ...
Iterative learning control for variable frequency drives
(
IEEE
, 2008 , Conference Paper)
Variable Frequency Drives (VFD) are subject to various types of disturbances especially cyclical ones. These periodic disturbances are difficult to compensate by conventional controllers. Repetitive control can only ...
Generalized dynamic spectrum access: An order statistics design perspective
(
Elsevier GmbH
, 2008 , Article)
A new adaptive multiple access scheme based on the theory of order statistics is introduced. The proposed algorithm employs a semi-random allocation mechanism that limits subchannel selection to the highest-gain subchannels. ...
Fast and memory-efficient algorithms for computing quadratic time–frequency distributions
(
Elsevier Inc
, 2013 , Article)
Algorithms for computing time–frequency distributions (TFDs) limit computation time by reducing numerical operations. But these fast algorithms do not reduce the memory load. This article presents four TFD algorithms to ...
