Flux melting of metal–organic frameworks
(Royal Society of Chemistry, 2019-03-28)
Recent demonstrations of melting in the metal-organic framework (MOF) family have created interest in the interfacial domain between inorganic glasses and amorphous organic polymers. The chemical and physical behaviour of ...
Should cross-border banking benefit from the financial safety net?
(Elsevier, 2016)
Using bank-level data from 84 countries, we find that a higher degree of bank internationalization is associated with higher interest expenses. Internationalization is proxied by a bank's share of foreign liabilities in ...
Effective Use of MOODLE in ELT Settings: An Application in SELI at Özyeğin University
(Istanbul Kültür University, 2010-05)
Technology in language teaching has been around for longer than one could imagine and the use of tape recorders, language laboratories and video in the classroom in the 1960s and 1970s (Dudeney and Hockly, 2007: 7) has ...
Pattern generation and compliant feedback control for quadrupedal dynamic trot-walking locomotion: experiments on roboCat-1 and hyQ
(Springer Science+Business Media, 2015-04)
In this paper, we introduce a method that synergistically combines an analytical pattern generator and a feedback controller frame, which are developed for the purpose of synthesizing dynamic quadrupedal trot-walking ...
Application of a disturbance observer based controller to improve vehicle ride
(Canadian Acoustical Association, 2019)
In this paper the application of a disturbance observer based control algorithm is proposed to improve the vehicle ride performance of a vehicle that has magnetorheological damper (MR Damper) suspension. The vehicle is ...
High power series elastic actuator development for torque-controlled exoskeletons
(Springer Nature, 2019)
This paper presents the development procedures of a high power series elastic actuator that can be used in torque-controlled exoskeleton applications as a high-fidelity torque source. In order to provide a high torque ...
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 ...
Variable ankle stiffness improves balance control: experiments on a bipedal exoskeleton
(IEEE, 2016-02)
This paper proposes a real-time balance control technique that can be implemented to bipedal robots (exoskeletons, humanoids) whose ankle joints are powered via variable physical stiffness actuators. To achieve active ...
Proof of concept for robot-aided upper limb rehabilitation using disturbance observers
(IEEE, 2015-02)
This paper presents a wearable upper body exoskeleton system with a model-based compensation control framework to support robot-aided shoulder-elbow rehabilitation and power assistance tasks. To eliminate the need for EMG ...
