A static three-phase to five-phase transformer based on Scott connection
(
Elsevier B.V.
, 2014 , Article)
Multiphase machines have become challenging candidates for safety-critical applications that require wide fault tolerant capabilities and higher system reliability. However, this adds more complexity to the adopted power ...
Analysis of local time-frequency entropy features for nonstationary signal components time supports detection
(
Elsevier Inc.
, 2014 , Article)
Identification of different specific signal components, produced by one or more sources, is a problem encountered in many signal processing applications. This can be done by applying the local time-frequency-based Rényi ...
HLS based hardware acceleration on the zynq SoC: A case study for fall detection system
(
IEEE
, 2014 , Conference Paper)
Fall detection is a major problem in healthcare systems, especially for elderly people who are the most vulnerable. It is important to design and implement not only an accurate fall detection system (FDS) but also a system ...
Doppler compensation for AF two way relaying over time varying UWA channels
(
IEEE
, 2014 , Conference Paper)
In this paper, we consider Doppler compensation for time varying underwater acoustic channels. The underlying system model comprises two sources, S1 and S2, communicating with each other through a relay, R. The transmission ...
Embedding of nonlinear systems in a linear parameter-varying representation
(
IFAC Secretariat
, 2014 , Conference Paper)
This paper introduces a systematic approach to synthesize linear parameter-varying (LPV) representations of nonlinear (NL) systems which are originally defined by control affine state-space representations. The conversion ...
A permanent-magnet machine with improved torque density based on a single layer winding layout for electric vehicle applications
(
IEEE
, 2014 , Conference Paper)
This paper proposes a novel single layer winding layout for a permanent magnet machine with improved torque density for electric vehicle applications. In this paper, two permanent-magnet (PM) machines with outer rotors and ...
Investigation of sensorless capacitor voltage balancing technique for modular multilevel converters
(
IEEE
, 2014 , Conference Paper)
Modular Multilevel converters (MMC) have become one of the most promising topologies for DC-AC conversion in recent years. Capacitor voltage balancing is a vital issue for proper operation of the MMC. Generally, conventional ...
Measuring time-varying information flow in scalp EEG signals: Orthogonalized partial directed coherence
(
IEEE
, 2014 , Article)
This study aimed to develop a time-frequency method for measuring directional interactions over time and frequency from scalp-recorded electroencephalographic (EEG) signals in a way that is less affected by volume conduction ...
Resources allocation for large-scale dynamic spectrum access system using particle filtering
(
IEEE
, 2014 , Conference Paper)
This paper proposes an efficient spectrum and power allocation solution for a large scale dynamic spectrum access (DSA) systems. Unlike conventional methods relying on optimization techniques which need huge computational ...
Multiple antenna cyclostationary-based detection of primary users with multiple cyclic frequency in Cognitive Radios
(
IEEE
, 2014 , Conference Paper)
In this paper, we study the problem of multiple antenna spectrum sensing by using cyclostationary features of Primary Users (PUs) signals in Cognitive Radios (CRs). We consider the general case of multiple antenna sensing ...
