    • Automatic Analysis of Large-scale Nanopore Data Using Hidden Markov Models 

      Zhang, Jianhua; Liu, Xiuling (IFAC-PapersOnLine;Volume 53, Issue 2, 2020, Peer reviewed; Journal article, 2020-04-14)
      In this paper we developed a modified Hidden Markov Model (HMM) to analyze the raw nanopore experimental data. Traditionally, prior to further analysis the measured nanopore data must be pre-filtered, but the filtering ...

      In this work, an open-source ROS interface based on KUKAVARPROXY for control of KUKA robots is compared to the commercial closed-source Robot Sensor Interface available from KUKA. This comparison looks at the difference ...

    • Design and verification of a sway-yaw control system for Surface Effect Ships using vent valves 

      Teigland, Håkon; Hassani, Vahid; Auestad, Øyvind Fidje (IFAC-PapersOnLine;Volume 52, Issue 21, 2019, Journal article; Journal article; Peer reviewed, 2019-12-26)
      For an offshore worker in the oil and gas industry, the helicopter transport is the activity associated with the highest risk. An alternative to helicopter crew transfers is to use Surface Effect Ships (SES) to transport ...

    • EMG Signals based Human Action Recognition via Deep Belief Networks 

      Zhang, Jianhua; Ling, Chen; Li, Sunan (IFAC-PapersOnLine;Volume 52, Issue 19, 2019, Journal article; Peer reviewed, 2019-12-24)
      Electromyography (EMG) signals can be used for action classification. Nonetheless, due to their nonlinear and time-varying properties, it is difficult to classify the EMG signals and it is critical to use appropriate ...

    • Hierarchical MPC of Hybrid Power Systems based on Fuzzy Discrete Abstraction 

      Zhang, Jianhua; Xia, Jiajun (IFAC-PapersOnLine;Volume 53, Issue 2, 2020, Peer reviewed; Journal article, 2020-04-14)
      A hierarchical control approach is proposed for hybrid systems with discrete-valued input based on fuzzy discrete abstraction and model predictive control (MPC) scheme. The system is firstly abstracted to a discrete event ...

    • Hybrid Collision Avoidance with Moving Obstacles 

      Chai, Yi; Hassani, Vahid (IFAC-PapersOnLine;Volume 52, Issue 21, 2019, Journal article; Peer reviewed, 2019-12-26)
      This paper proposes a hybrid collision avoidance (COLAV) approach based on the integration of a global path planning algorithm and a reactive collision avoidance technique. This combination provides a robust path planning ...

    • Operator Performance Prediction based on Fuzzy Modeling Approach 

      Zhang, Jianhua; Yin, Zhong (IFAC-PapersOnLine;Volume 53, Issue 2, 2020, Peer reviewed; Journal article, 2021-04-14)
      In this paper, physiological signals were measured from five participants, each participating in two sessions of experiment with identical experimental procedure. A simulation platform, AutoCAMS (Automation-enhanced Cabin ...

    • Selection of Optimal EEG Electrodes for Human Emotion Recognition 

      Zhang, Jianhua; Chen, Peng (IFAC-PapersOnLine;Volume 53, Issue 2, 2020, Peer reviewed; Journal article, 2021-04-14)
      In recent years, emotion recognition has attracted increasing interest from researchers from diverse fields. Because of their intrinsic correlation with emotions, physiological signals based emotion recognition method is ...
