Simulation-based design and locomotion control implementation for a lower body exoskeleton
(IEEE, 2022)
This paper proposes a simulation-based design and locomotion control methodology for an exoskeleton that is aimed at providing assistance to users with ambulatory difficulties. To increase the power-to-weight ratio while ...
Effects of interlayer on the friction stir spot welding of stainless steel
(Elsevier, 2022-01)
Comparison of Interlayer Friction Stir Spot Welding (IL-FSSW) and conventional Friction Stir Spot Welding (FSSW) of 304 stainless steel is presented in this study. IL-FSSW is introduced as a novel spot-welding technique ...
Graphene as a piezoresistive material in strain sensing applications
(MDPI, 2022-01-12)
High accuracy measurement of mechanical strain is critical and broadly practiced in several application areas including structural health monitoring, industrial process control, manufacturing, avionics and the automotive ...
Towards crutch-free 3-D walking support with the lower body exoskeleton Co-Ex: Self-balancing squatting experiments
(Springer, 2022)
In this paper, we succinctly present the hardware properties and capabilities of the lower body exoskeleton Co-Ex, which was developed to attain self-balancing and crutch-free walking support for those experiencing ambulatory ...
Advanced surface enhancement of a high strength aluminum alloy through friction stir processing
(Springer, 2022)
The current study investigates the effect of severe plastic deformation (SPD) on the mechanical behavior of a commercial aluminum alloy (Al7075). In-process cooled friction stir processing (FSP) was used to enhance the ...
HandMECH—Mechanical hand prosthesis: Conceptual design of a two degrees-of-freedom compliant wrist
(Springer, 2022)
A compliant wrist joint is important for positioning the hand in different positions to perform various daily tasks. It is also important that the wrist is able to achieve sufficient range of motion (RoM). The RoM is ...
HandMECH—Mechanical hand prosthesis: Conceptual design of the hand compartment
(Springer, 2022)
In this study, conceptual design of the hand compartment of a body-powered hand prosthesis, HandMECH, is presented. HandMECH is a body-powered prosthesis and the hand compartment is designed according to human finger size ...
Thermal and optical performance characterization of bare and phosphor converted LEDs through package level immersion cooling
(Elsevier, 2022-06-15)
Increased demand for high flux electronics requires creative and affordable thermal management approaches to meet the performance and lifetime expectations. In the present study, optical and thermal improvements of a new ...
Effect of build parameters on the compressive behavior of additive manufactured CoCrMo lattice parts based on experimental design
(MDPI, 2022-07)
Due to their high specific strength, toughness, and corrosion and wear resistance characteristics, CoCrMo alloys are widely used in different industries and applications: wind turbines and jet-engine components, orthopedic ...
Centroidal momentum observer: Towards whole-body robust control of legged robots subject to uncertainties
(IEEE, 2022)
This paper aims to provide robust dynamic motion control and eliminate parameter uncertainty in single-legged robots with a centroidal momentum-based control algorithm. In order to ensure the continuity of the movement ...
