Dynamic stability of an axially loaded elastically restrained column
(2023)The dynamic stability of axially loaded columns is a key problem in structural analysis, and in earthquake engineering particularly. Experience has shown that columns occasionally buckle when subject to dynamic axial ... -
Mobile robot tank with GPU assistance
(2014-01-22)Robotic research has been costly and tremendously time consuming; this is due to the cost of sensors, motors, computational unit, physical construction, and fabrication. There are also a lot of man hours clocked in for ... -
Modal identification of time-varying structures using the blind source separation techniques
(2016)In last few decades, Structural Health Monitoring (SHM) has been an indispensable subject in the field of vibration engineering. With the aid of modern sensing technology, SHM has garnered significant attention towards ... -
A nonlinear energy sink with energy harvester
(2014-12-11)The transfer of energy between systems is a natural process, manifesting in many different ways. In engineering transferable energy can be considered wanted or un- wanted. Specifically in mechanical systems, energy transfer ... -
Numerical analysis of discontinuous structures: static and dynamic
(2018)Discontinuous beam structures can be found in various applications such as adhesive bonded joints and piezoelectric energy harvesters. In adhesive bonded joint design, the single lap joint is commonly used and is constructed ... -
On the control methedologies of a novel active vibration isolator
(2010)The work presented in this thesis is motivated by the need for new and effective methods to isolate vibrations in the rapidly growing technological sector, with particular interest in the control methodologies for active ... -
Piezoelectric Energy Harvesting with a Nonlinear Energy Sink
(2016)Energy transfer from one system to another system, or vice versa, is happening constantly in many processes with various forms. Vibration in machines or structures can be considered as a form of energy transfer from a ... -
Simultaneous vibration suppression and energy harvesting with a non-traditional vibration absorber
(2017)The dynamic vibration absorber, or tuned mass damper, has been one of the most commonly used passive vibration control devices over the past hundred years. With an optimally designed vibration absorber, significant vibration ... -
A Tunable high-static-low-dynamic-stiffness isolator and a fuzzy-neural network based active control isolator
(2009)Excessive vibration can be detrimental to a wide variety of structures and machines. Vibration isolation is an effective means to suppress vibration. This study focuses on development of some new techniques to improve ... -
A tunable multi-stable piezoelectric vibration energy harvester
(2021)The vibration energy harvester is intended to convert ambient environmental energy into electrical energy. It has great potential to be an alternative to the conventional battery in low-power electric devices. A traditional ... -
Vibration control using switchable stiffness
(2015-01-13)Over the last decade, the switchable stiffness (SS) control strategy has seen renewed academic interest due to the need for effective vibration control techniques. The SS control strategy involves switching the system’s ... -
Vibration suppression and energy harvesting with a variant nonlinear energy sink
(2018)Vibration control is aimed to suppress or eliminate unwanted vibration to ensure proper operation of machines. On the other hand, energy harvesting intends to scavenge energy from ambient vibrations to power electronical ...
