Design of 3-DOF parallel manipulators for micro-motion applications
(2009-08-01)
This thesis presents two unique micro-motion parallel kinematic manipulators (PKM):
a three degrees of freedom (3-DOF) micro-motion manipulator and a 3-DOF micro-motion
manipulator with actuation redundancy. The 3-DOF ...
Joint uplink-downlink beamforming in multi-antenna relaying schemes
(2009-11-01)
The thesis examines the problem of joint receive and transmit beamforming for a wireless
network which consists of one relay node equipped with multiple antennas. The
transmitter and the receiver are single antenna ...
Modeling and vibration analysis of a rocking–mass gyroscope system
(2008-04-01)
Rocking-mass gyroscope consists of an assembly of four cantilever beams with a rigid mass attached to them in the middle subjected to base rotations. Due to the gyroscope effect, the beams undergo coupled flexural-torsional ...
Design and development of a novel lightweight long-reach composite robotic arm
(2009-08-01)
Metallic robotic arms, or manipulators, currently dominate automated industrial operations, but
due to their intrinsic weight, have limited usefulness for large-scale applications in terms of
precision, speed, and ...
Novel tele-operation of mobile-manipulator systems
(2009-08-01)
A novel algorithm for the simplified tele-operation of mobile-manipulator systems is
presented. The algorithm allows for unified, intuitive, and coordinated control of
mobile manipulators, systems comprised of a robotic ...
Evaporative heat and mass transfer with solubility driven solidification of aqueous droplet flows
(2009-03-01)
Nuclear-based hydrogen production via thermochemical water decomposition using a copper-chlorine cycle consists of a series of chemical reactions that split water into hydrogen and oxygen. This is accomplished through ...
Performance assessment of transient behaviour of small wind turbines
(2009-08-01)
Small wind turbine installations have a variety of potential uses, each with unique
performance demands and operating conditions. Many applications require that the
turbine is placed in wind conditions that are not ideal ...
Advancing the technology development for better quality wood plastic composites: process ability study
(2009-03-01)
Wood Plastic Composites (WPC) have advantages over natural wood such as improved
stiffness, recyclability, and waste minimization. However, issues such as the difficulty of
processing WPC with conventional methods, volatile ...
Detecting and preventing the electronic transmission of illicit images
(2009-04-01)
The sexual exploitation of children remains a very serious problem and is rapidly increasing globally through the use of the Internet. This work focuses on the current methods employed by criminals to generate and distribute ...
Design and analysis of a three degrees of freedom (DOF) parallel manipulator with decoupled motions
(2009-04-01)
Parallel manipulators have been the subject of study of much robotic research during the past three decades. A parallel manipulator typically consists of a moving platform that is connected to a fixed base by at least two ...
