Case Studies in Thermal Engineering, 2022 A gas power engine is expected to output work or power through cycle, and the work is expected as much as possible in terms of viewpoints of a unit fuel, a unit volume of an engine, or a unit displaced volume of an engine. Evaluation of gas power engines

Notions of controllability for quantum mechanical systems [PDF]
Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002 In this paper, we define four different notions of controllability of physical interest for multilevel quantum mechanical systems. These notions involve the possibility of driving the evolution operator as well as the state of the system. We establish the connections among these different notions as well as methods to verify controllability.

Constraint Control of Nonholonomic Mechanical Systems [PDF]
Journal of Nonlinear Science, 2017 We derive an optimal control formulation for a nonholonomic mechanical system using the nonholonomic constraint itself as the control. We focus on Suslov's problem, which is defined as the motion of a rigid body with a vanishing projection of the body frame angular velocity on a given direction $\boldsymbolξ$. We derive the optimal control formulation,

Reactive Mechanism of Cognitive Control System [PDF]
Cerebral Cortex, 2010 The prefrontal cortex (PFC) is thought to modulate the neural network state in favor of the processing of task-relevant sensory information prior to the presentation of sensory stimuli. However, this proactive control mechanism cannot always optimize the network state because of intrinsic fluctuation of neural activity upon arrival of sensory ...

Energy shaping control of underactuated mechanical systems with fluidic actuation [PDF]
, 2022 Energy shaping is a remarkably effective control strategy which can be applied to a wide range of systems, including underactuated mechanical systems. However, research in this area has generally neglected actuator dynamics.

Multiple-Joint Pedestrian Tracking Using Periodic Models
Sensors, 2020 Estimating accurate positions of multiple pedestrians is a critical task in robotics and autonomous cars. We propose a tracker based on typical human motion patterns to track multiple pedestrians.

A power-based perspective of mechanical systems [PDF]
, 2005 This paper is concerned with the construction of a power-based modeling framework for a large class of mechanical systems. Mathematically this is formalized by proving that every standard mechanical system (with or without dissipation) can be written as ...
