Conceptual design of a fully passive transfemoral prosthesis to facilitate energy-efficient gait
(IEEE, 2018-12)
In this paper, we present the working principle and conceptual design toward the realization of a fully-passive transfemoral prosthesis that mimics the energetics of the natural human gait. The fundamental property of the ...
Challenges for radiative transfer 1: towards the effective solution of conjugate heat transfer problems
(Elsevier, 2018-12)
This paper lists crucial challenges in radiative transfer with the objective of gathering information on improving and choosing methods for solving conjugate heat transfer problems. Developments in computational and ...
Effect of electrostatic stabilization on thermal radiation transfer in nanosuspensions: Photo-thermal energy conversion applications
(Elsevier, 2018-04)
Solar thermal collectors are among the most important photo-thermal energy conversion systems. Effectiveness of these systems is measured by the ability of working fluid to absorb incident radiative energy. Although ...
On occupant behavior and innovation studies towards high performance buildings: a transdisciplinary approach
(MDPI, 2018-10-06)
With ever-increasing population and urbanization, it is crucial to decrease energy density in the built environment without sacrificing occupants’ comfort and well-being. This requires consideration of technological ...
Radiative energy and exergy analyses of spectrally-selective surfaces for CSP systems
(Inderscience Enterprises Ltd., 2018)
This work presents a new methodology for calculations of spectral radiative energy and radiative exergy to evaluate the performances of concentrated solar power (CSP) systems. Spectral radiative properties and the operating ...
Interaction between free-stream turbulence and tip-vortices of wind turbine blades with and without winglets
(IOP Publishing, 2018)
Experimental investigations of the free-stream turbulence impact on the tip-vortices generated in wind turbine blades have been performed. The investigation is done by exposing an efficient laboratory scale wind turbine ...
Active-grid turbulence effect on the topology and the flame location of a lean premixed combustion
(Society of Thermal Engineers of Serbia, 2018)
Lean premixed combustion under the influence of active-grid turbulence was computationally investigated, and the results were compared with experimental data. The experiments were carried out to generate a premixed flame ...
Characterization of turbulence generated by an active grid with individually controllable paddles
(Springer, 2018)
An active grid with individually controllable paddles was constructed to generate strong turbulence (Reλ>200). Measurements of turbulence quantities using the hot-wire technique were conducted in a wind tunnel along the ...
Analysis of sustainable materials for radiative cooling potential of building surfaces
(MDPI AG, 2018)
The main goal of this paper is to explore the radiative cooling and solar heating potential of several materials for the built environment, based on their spectrally-selective properties. A material for solar heating, ...
Sliding mode control of an electromechanical solenoid actuator for soft landing
(IEEE, 2018-10-08)
Electromechanical solenoid actuators are widely used in industrial applications that require fast and linear motion. High velocities can be achieved in small stroke lengths; in turn the motion results with high-velocity ...
