Learning to exploit passive compliance for energy-efficient gait generation on a compliant humanoid
(Springer Nature, 2019-01)
Modern humanoid robots include not only active compliance but also passive compliance. Apart from improved safety and dependability, availability of passive elements, such as springs, opens up new possibilities for improving ...
Stable control of force, position, and stiffness for robot joints powered via pneumatic muscles
(IEEE, 2019-12)
This paper proposes a novel controller framework for antagonistically driven pneumatic artificial muscle (PAM) actuators. The proposed controller can be stably configured in both torque-stiffness control and position-stiffness ...
On the mechanical behavior of accumulative roll bonded lightweight composite
(IOP Publishing, 2019-09)
Multi-layered composites have received great interest due to their enhanced mechanical and physical properties. In this study, Al6061/Al2024 composites were processed by accumulative roll bonding as a severe plastic ...

Influence of turbulent flow characteristics on flame behaviour in diffuser combustors
(Elsevier, 2019-03-01)
The influence of turbulence on flame location in a diffuser-type combustor is the focus of this study. Two types of diffuser combustors were selected to study the influence of turbulence intensity and length scale on flame ...
Impact of functional nanofluid coolant on radiator performance
(ASME, 2019-08)
While a number of liquids are preferred in many heating and cooling applications, their thermal capacity can be a limiting factor in many thermal systems. Therefore, a series of methods such as use of mixtures of two or ...
Numerical assessment of the factors controlling the acoustic response of wind turbine blades
(Canadian Acoustical Association, 2019)
The blades of wind turbine are the most critical parts of the wind turbine system, which contribute to noise generated by wind turbine due to excitation from air streams across them. In this numerical study, the effect of ...
Co-ex: A torque-controllable lower body exoskeleton for dependable human-robot co-existence
(IEEE, 2019-06)
In this paper, we present our research study concerning the design and development of an exoskeleton that aims to provide 3D walking support with minimum number of actuators. Following a prior simulation study, the joint ...
Influence of warm rolling and aging on the microstructural evolution and mechanical behavior of AZ31 magnesium alloy
(American Institute of Physics Inc., 2019)
The microstructural evolution and tensile properties of AZ31 after warm rolling and different aging methods and conditions were investigated. The warm rolling was conducted on the as-received AZ31 after homogenization at ...
Effect of processing parameters on the strength of keyhole free friction stir spot aluminum welds
(American Institute of Physics Inc., 2019)
Intermediate layer friction stir spot welding (IL-FSSW) is a new solid-state welding method appropriate for making spot joints, particularly in light-weight materials, especially notable on account of the weight saving ...
