Analysis of sit-to-stand in sit-to-walk with an admittance controlled robotic walker
Nihon Kikai Gakkai ronbunshu, 2023 We examined the effects of the robotic walker’s dynamic characteristics on postural stability, operating forces, ground reaction forces (GRF), and muscle activity in young healthy adults during sit-to-stand (STS) and sit-to-walk (STW) tasks.

Dynamic normal forms and dynamic characteristic polynomial
Theoretical Computer Science, 2008 We present the first fully dynamic algorithm for computing the characteristic polynomial of a matrix. In the generic symmetric case our algorithm supports rank-one updates in O(n^2 log n) randomized time and queries in constant time, whereas in the general case the algorithm works in O(n^2 k log n) randomized time, where k is the number of invariant ...

Controlling the Q-Point in Distributed Feedback Lasers Using a Numerical Optimization Methodology [PDF]
Engineering and Technology Journal, 2019 In this paper, a new methodology for controlling the Q-point in the distributed feedback (DFB) lasers is proposed. The method based on reducing the DFB transient period (TP) by optimizing laser’s model parameters numerically.

A characteristic dynamic mode decomposition [PDF]
Theoretical and Computational Fluid Dynamics, 2019 Temporal or spatial structures are readily extracted from complex data by modal decompositions like Proper Orthogonal Decomposition (POD) or Dynamic Mode Decomposition (DMD). Subspaces of such decompositions serve as reduced order models and define either spatial structures in time or temporal structures in space.

Study on the Coupling Relationship between Wear and Dynamics in Planetary Gear Systems
Machines, 2023 The occurrence of wear is hard to avoid in gear systems because of their transmission principle. Wear will lead to a deviation of the system’s performance from the design objectives or even failure.

Dynamic characteristics of oxygen consumption [PDF]
BioMedical Engineering OnLine, 2018 Previous studies have indicated that oxygen uptake ([Formula: see text]) is one of the most accurate indices for assessing the cardiorespiratory response to exercise. In most existing studies, the response of [Formula: see text] is often roughly modelled as a first-order system due to the inadequate stimulation and low signal to noise ratio.
