A novel driving pattern to actualize haptic effects in mobile devices
(IEEE, 2021-05)
Haptic interactions in consumer devices have become more critical with immersive streaming content by including high-resolution video and sound as well as tactile information. Mobile devices such as tablets and smartphones ...
Robust locomotion control of a self-balancing and underactuated bipedal exoskeleton: Task prioritization and feedback control
(IEEE, 2021-07)
This letter presents a study to understand how an underactuated bipedal exoskeleton with an arbitrary human user can exhibit robust dynamic walking behavior despite severe parameter uncertainty and external disturbances. ...
Effect of layer architecture on the mechanical behavior of accumulative roll bonded interstitial free steel/aluminum composites
(Elsevier, 2021-06-22)
Multi-layered interstitial free (IF) steel/aluminum (Al) composites were fabricated by the accumulative roll bonding (ARB) method. Two types of IF steel/Al6061 dissimilar layered metal composites (LMC) with varied stacking ...
A numerical investigation into frost formation under impinging flow conditions
(IEEE, 2021)
Frost formation is an undesired phenomenon for a wide range of practical applications as it diminishes amount of heat dissipation from heat transfer regions. In this paper, frost growth process on a vertically suspended ...
Particle based investigation of self-heating effect of phosphor particles in phosphor converted light emitting diodes
(Elsevier, 2021-03)
Since 2003, self-heating effect of phosphor which reduces the efficacy and reliability of phosphor conversion (Pc) light emitting diodes (LEDs), has been a growing research area of opto-thermal Pc-LED modeling. However, ...
Identification and evaluation of cracks in electrostatically actuated resonant gas sensors using Harris Hawk / Nelder Mead and perturbation methods
(Techno-Press, 2021-01)
In this paper we study the static deflection, natural frequency, primary resonance of an electrostatically actuated cracked gas sensor. Besides, a novel hybrid metaheuristic algorithm is proposed to detect the location and ...
On the high-temperature flow response of friction stir processed magnesium metal matrix composites
(ASME, 2021-01-01)
In the current work, multi-pass friction stir processing (FSP) was utilized to fabricate samples of fine-grained aluminum-zinc (AZ) magnesium alloy and its metal matrix composite (MMC). The microstructure and high-temperature ...
On the individual droplet growth modeling and heat transfer analysis in dropwise condensation
(IEEE, 2021-10)
The low convective coefficient at condenser part of spreaders and vapor chambers due to film blanket blocking encourages utilizing dropwise condensation (DWC). Challenges exist in the experimental characterization of DWC, ...
A coupled material removal model for chemical mechanical polishing processes
(IOP Publishing, 2021-10-01)
Chemical mechanical polishing (CMP) is a process used to obtain planarized surfaces in microelectronic device manufacturing. The planarization is achieved by material removal from the wafer surface by synergistic effect ...
Tepki kuvveti gözetleyici tabanlı tork kontrolü
(Gazi Üniversitesi, 2021-12)
In this article, a reaction force observer-based torque controller was designed and experimentally implemented to a non-backdrivable actuator unit. Torque control is of importance when considering physical human-robot ...
