Asymptotic stability of time-varying distributed parameter semi-linear systems
(
IFAC
, 2014 , Conference Paper)
The asymptotic behaviour is studied for a class of non-linear distributed parameter time-varying dissipative systems. This is achieved by using time-varying infinite-dimensional Banach state space description. Stability ...
Outage analysis of hybrid FSO/RF systems based on finite-state Markov chain modeling
(
IEEE
, 2014 , Conference Paper)
In this paper, we analyze the outage probability of a hybrid free-space optical/radio-frequency (FSO/RF) communication system with soft-switching. In soft-switching approach, either one of the links or both links can be ...
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 ...
On the power efficiency for cognitive radio networks with multiple relays
(
IEEE
, 2014 , Conference Paper)
In this paper, we study and analyze cooperative cognitive radio networks with multiple secondary users (SUs). Each SU is considered a prospective relay for the primary user (PU) besides having its own data demand. The ...
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 ...
Secret key generation based on channel and distance measurements
(
IEEE Computer Society
, 2014 , Conference Paper)
Within the paradigm of physical layer secrecy, typically a physical layer specific characteristic is used as key generator to guarantee information hiding from eavesdroppers. In this paper, we propose a novel secret key ...
A model driven framework for secure outsourcing of computation to the cloud
(
IEEE Computer Society
, 2014 , Conference Paper)
This paper presents a model driven approach to define then coordinate the execution of protocols for secure outsourcing of computation of large datasets in cloud computing environments. First we present our Outsourcing ...
HVDC shunt tap based on series-input parallel-output DC-AC multi-module VSCs with DC voltages balancing
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Conventionally, tapping-off a small amount of power from an HVDC transmission line to a three-phase local network can be achieved using a DC-to-AC voltage source converter (VSC) followed by a step down transformer. In order ...
On the use of time-frequency features for detecting and classifying epileptic seizure activities in non-stationary EEG signals
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper proposes new time-frequency features for detecting and classifying epileptic seizure activities in non-stationary EEG signals. These features are obtained by translating and combining the most relevant time-domain ...
Robust Hybrid EKF approach for state estimation in multi-scale nonlinear singularly perturbed systems
(
IEEE
, 2014 , Conference Paper)
In this paper a general framework is developed for state estimation in a class of nonlinear continuous-time singularly perturbed systems. Our approach is based on the hybrid extended Kalman filter in which observations are ...
