• Efficient spatial compliance analysis of general initially curved beams for mechanism synthesis and optimization 

  Wu, Ke; Zheng, Gang; Hao, Guangbo (Elsevier B.V., 2021-04-09)

  Compliant Mechanisms (CMs) present several desired properties for mechanical designs. Conventional rigid-body mechanisms composed of rigid links connected at kinematic joints, serve as devices to transfer motion, force and ...
• Design and hybrid control of a two-axis flexure-based positioning system 

  Petri, Elena; Hao, Guangbo; Kavanagh Richard C. (Springer Nature Switzerland AG, 2021-03-07)

  In this paper, an accurate, large range, two-axis compliant positioning system is described and the performance of the implemented control system is analysed. The characteristics of two independently controlled axes are ...
• Optimising photovoltaic-centric hybrid power systems for energy autonomy 

  Olówósejéjé, Samuel; Leahy, Paul G.; Morrison, Alan P. (Elsevier, 2021-04-12)

  In recent years, emphasis has been placed on the design and implementation of sustainable energy system solutions to combat the adverse environmental impact of emissions from the power and transportation sectors. This study ...
• A flexure motion stage system for light beam control 

  Riza, Mehdi; Hao, Guangbo (Springer, 2018-10-10)

  This paper presents the design of an improved tip-tilt-piston compliant/flexure motion stage for steering light beam. The motion stage is actuated by three linear stepper motors in an open-loop control. Using a laser and ...
• GHz bandwidth semipolar (112¯2) InGaN/GaN light-emitting diodes 

  Dinh, Duc V.; Quan, Zhiheng; Roycroft, Brendan; Parbrook, Peter J.; Corbett, Brian (Optical Society of America, 2016-12-12)

  We report on the electrical-to-optical modulation bandwidths of non-mesa-etched semipolar (112¯2) InGaN/GaN light-emitting diodes (LEDs) operating at 430–450 nm grown on high-quality (112¯2) GaN templates, which were ...
