A new fingerprint design using optical orthogonal codes
(2014)Digital fingerprinting has been proposed to restrict illegal distribution of digital media, where every piece of media has a unique fingerprint as an identifying feature that can be traceable. However, fingerprint systems ... -
Adaptive backstepping control of quadrotors with neural-network
(2018)A quadrotor is a type of unmanned aerial vehicles. It has been widely used in aerial photography. The quadrotor has the capability of vertical takeoff and landing, which is very useful in small or narrow areas. The ... -
Applications of golay complementary sequences in mc-cdma and compressed sensing
(2012-11-10)This thesis consists of two separate topics involved with Golay complementary sequences. In the first part, we present results of an experimental investigation where the distribution of peak-to-average power ratio (PAPR) ... -
Attitude control for a quadrotor UAV using adaptive fuzzy backstepping
(2017)With improvements on automation, computer, electronics and other technologies, applications of unmanned aerial vehicles (UAVs) have expanded from pure military field to civilian areas. As a multirotor aircraft, a quadrotor ... -
Autonomous navigation using image processing
(2016)In the recent years, the pursuit intelligent and self-operated machines have increased. The human user is to be completely eliminated or minimized as much as possible. It is also popular now to observe machines that are ... -
Class of service based protection in multi-layered networks with SRLG constraints
(2009)Today's optical mesh networks are multi-layered networks, powered by bandwidth-hungry applications that can encounter multiple concurrent failures due to a single fault. Class of Service (CoS) is a level of availability ... -
Coded based protection in mesh networks
(2010)Since the Internet revolution of the 1990s; ever increasing levels of connectivity have been integrated into society. This has ushered in the era of globalization and a new plateau in prosperity. Credit for this ... -
A Comparative study of min-sum based decoding algorithms for low density parity check codes
(2012-11-10)The demand for large scale broadband networks is gaining immense popularity for convenient access of information. A common concern of transmitting data through a wireless medium is the effects of noise on the signal. ... -
Comprehensive Ontology Design for Autism Spectrum Disorder
(2016)Ontology is a formal explicit description of concepts in the knowledge domain. In recent years, developing ontology in different domains is a hot topic for many researchers, especially in the medical field because of the ... -
Control of doubly fed induction generator based wind energy conversion system
(2014-01-22)The doubly fed induction generator (DFIG) is widely used in today’s wind energy conversion industry. The DFIG is essentially a wound rotor induction generator in which the rotor circuit can be controlled by external devices ... -
Design and Development of Dual Tuned 19F and 1H RF Birdcage Coils for Small Animal MRI at 3T
(2015)Conventional proton (1H) magnetic resonance imaging (MRI) is generally insensitive to the lung due to the low tissue density and other complicating factors. On the other hand, inhaled inert fluorinated gas MRI is a ... -
Design methodology for Class D ultrasound transducer drivers
(2021)Ultrasound refers to sound waves with frequencies above the upper limit of human hearing. Due to the high frequency, the energy can be concentrated and used for therapeutic applications, such as ultrasound imaging ... -
