Adaptive finite-time synchronized control of multi-robotic fiber placement system with model uncertainties and disturbances

Author(s): Zhang R; Wang Y; Xie W; Li P; Tan H; Jiang Y;

The use of multiple robots to manufacture composite components represents a critical development direction for fiber placement systems (FPSs). In multi-robotic fiber placement systems (MRFPSs) with heterogeneous mechanical structures, robots collaborate to perform fiber placement tasks. Consequently, robot synchronization emerges as a primary factor in de ...

Distributed adaptive sliding mode control with deep recurrent neural network for cooperative robotic system in automated fiber placement

Author(s): Zhu N; Xie WF;

In this article, a distributed control strategy using an adaptive sliding mode controller (ASMC) is proposed for a 13-degree-of-freedom (13-DOF) cooperative robotic system in the field of automated fiber placement (AFP). A distributed control structure with event-triggered mechanism is developed to guarantee the desired cooperation performance and reduce ...

Correlations of pilot trainees brainwave dynamics with subjective performance evaluations: insights from EEG microstate analysis

Author(s): Zhao M; Law A; Su C; Jennings S; Bourgon A; Jia W; Larose MH; Bowness D; Zeng Y;

Objective: This study aims to investigate the relationship between the subjective performance evaluations on pilot trainees' aircraft control abilities and their brainwave dynamics reflected in the results from EEG microstate analysis. Specifically, we seek to identify correlations between distinct microstate patterns and each dimension included in th ...

The PolyVent educational platform: An open mechanical ventilation platform for research and education

Author(s): Read RL; Bechard N; Suturin V; Zuiderwijk A; Mellenthin M;

The PolyVent is an open source mechanical ventilator meant for research and education. It prioritizes openness, modularity, repairability, and modifiability. An ESP32 microcontroller controls a proportional valve which precisely modulates pressure and flow from a mixing chamber into the airway. This chamber is fed with pressurized oxygen and medical air. ...

Reappraising beliefs about losing control: An experimental investigation

Author(s): Fridgen CPEA; Radomsky AS;

Background and objectives: Beliefs about losing control over one's thoughts, emotions, behaviours, and/or bodily functions have been shown to cause obsessive-compulsive symptoms. The cognitive model of obsessive-compulsive disorder (OCD) suggests that catastrophic misappraisals of intrusions will lessen if underlying maladaptive beliefs are effectivel ...

Further analyses of appraisals of losing control and other OCD-related cognitions: A quasi-experimental investigation

Author(s): Sandstrom A; Radomsky AS;

Background and objectives: Cognitive models of OCD posit that dysfunctional beliefs contribute to the maintenance of symptoms. In addition to well-established belief domains, beliefs about losing control has been identified as a novel cognitive domain which may influence OCD phenomena, including other dysfunctional beliefs. However, the exact nature of th ...

Predictive heating load management and energy flexibility analysis in residential sector using an archetype gray-box modeling approach: Application to an experimental house in Québec

Author(s): Abtahi M; Athienitis A; Delcroix B;

This paper presents a methodology to develop archetype gray-box models and use them in an economic model-based predictive control algorithm to simulate optimal heating load management in response to a newly-introduced static time-of-use tariff for Québec's residential sector, rate Flex-D. The methodology is evaluated through a case study, wherein in s ...

Position-based visual servoing of a 6-RSS parallel robot using adaptive sliding mode control

Author(s): Zhu N; Xie WF; Shen H;

The trajectory tracking control of parallel robots is challenging due to their complicated dynamics and kinematics. This paper proposes a position-based visual servoing (PBVS) approach for a 6-Revolute-Spherical-Spherical (6-RSS) parallel robot using adaptive sliding mode control in Cartesian space. A photogrammetry sensor C-Track 780 in the eye-to-hand c ...

Weight-control compensatory behaviors patterns and correlates: a scoping review

Author(s): Yuan TY; Bouzari N; Bains A; Cohen TR; Kakinami L;

Objective: Weight-control compensatory behaviors appear to be a commonly utilized strategy for health management. Individuals engaging in such behaviors believe that the negative consequences from unhealthy behaviors will be neutralized by the positive consequences of healthy behaviors. Existing research has not reached a consensus on whether such behavio ...

The effects of a 12-week combined motor control exercise and isolated lumbar extension intervention on lumbar multifidus muscle stiffness in individuals with chronic low back pain

Author(s): Tornblom A; Naghdi N; Rye M; Montpetit C; Fortin M;

Introduction: Exercise therapy is the primary endorsed form of conservative treatment for chronic low back pain (LBP). However, there is still conflicting evidence on which exercise intervention is best. While motor control exercise can lead to morphological and functional improvements of lumbar multifidus muscle in individuals with chronic LBP, the effec ...
