An online signature verification system for forgery and disguise detection
(
Springer
, 2012 , Conference Paper)
Online signatures are acquired using a digital tablet which provides all the trajectory of the signature as well as the variation in pressure with respect to time. Therefore, online signature verification achieves higher ...
Brushless doubly fed induction machine as a variable frequency transformer
(
IEEE
, 2012 , Conference Paper)
Variable frequency transformer (VFT) has been recently used as an alternative to HVDC to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster ...
Time frequency and array processing of non-stationary signals
(2012 , Article)
The special issue of EURASIP Journal on Advances in Signal Processing 2012 focuses on the synergistic relationship between time-frequency methods and array signal processing methods and addresses recent developments. In ...
Multiple sensor fault diagnosis for non-linear and dynamic system by evolving approach
(
2012 3rd Annual IEEE Prognostics and System Health Management Conference, PHM-2012
, 2012 , Conference Paper)
Reliability of sensor measurement is vital to assure the performance of complex and nonlinear industrial operation. In this paper, the problem of designing and development of a data-driven multiple sensor fault detection ...
Towards cost-effective maintenance of power transformer by accurately predicting its insulation condition
(2012 , Conference Paper)
Insulation resistance (IR) or Megger test has been commonly performed in both preventive and corrective maintenance activities to verify power transformers' insulation condition. Other insulation diagnosis tests such as ...
Polypharmacy in the management of patients with schizophrenia on risperidone in a tertiary-care hospital in Malaysia
(2012 , Article)
The present study was conducted primarily to determine the occurrence of polypharmacy in patients with schizophrenia on risperidone. The secondary aim was to ascertain the incidence of inappropriate prescribing with ...
Nanofeatures of resorcinol-formaldehyde carbon microspheres
(
Elsevier
, 2012 , Article)
Resorcinol-formaldehyde activated carbon xerogels were synthesized at certain conditions, and their morphology was studied experimentally to examine their detailed nature on the nanoscale level, which has not been reported ...
Generalized Mean Phase Coherence for asynchrony abnormality detection in multichannel newborn EEG
(2012 , Conference Paper)
Inter-hemispheric asynchrony within the multichannel recordings of newborn EEG is associated with abnormal functionality of the newborn brain. Mean Phase Coherence (MPC) as a bivariate phase synchrony measure is widely ...
Performances analysis of SEC based transmit diversity systems with MRC receivers
(
IEEE
, 2012 , Conference Paper)
Switch and Examine combining (SEC) diversity scheme is one of the simplest yet efficient diversity schemes. Earlier in [1] and [2], we proposed sequential power loading algorithm to reduce the average power used at the ...
Modeling security importance and preferences of software services
(
IEEE
, 2012 , Conference Paper)
This paper proposes a modeling framework on how to specify security preferences and importance of software services, and compute a quantifiable value. Our approach advocates for an automatic calculation of the results of ...
