A Method for Determining the Optimal Location of a Distributed Sensor/Actuator

open access: yesShock and Vibration, 1994
The optimal location problem of distributed sensor/actuator for observation and control of a flexible structure is investigated. Using a property of controllability and observability grammian matrices, this approach employs a nonlinear optimization ...

Pole Assignment for Active Vibration Control of Linear Vibrating Systems through Linear Matrix Inequalities

open access: yesApplied Sciences, 2020
This paper proposes a novel method for pole placement in linear vibrating systems through state feedback and rank-one control. Rather than assigning all the poles to the desired locations of the complex plane, the proposed method exactly assigns just the

Phosphorylase: control and activity

open access: yesPhilosophical Transactions of the Royal Society of London. B, Biological Sciences, 1981
Recent results from the crystallographic studies on glycogen phosphorylase b at 3 A resolution are reviewed with special reference to other themes of the meeting. The structural similarity of the fold of 150 residues in phosphorylase to that observed in lactate dehydrogenase is discussed and the binding sites for ...

Design of a Maglev Inertial Actuator with High Mass Power Ratio for Lateral Vibration Control of Propulsion Shafting

open access: yesActuators, 2021
The maglev inertial actuators with high power and mass maybe effective for lateral vibration control of a propulsion shafting. But the mass power ratio of the actuators currently in use is too small to meet the requirements.

Minimum Initial Marking Estimation in Labeled Petri Nets With Unobservable Transitions

open access: yesIEEE Access, 2019
In the literature, researchers have been studying the minimum initial marking (MIM) estimation problem in the labeled Petri nets with observable transitions. This paper extends the results to labeled Petri nets with unobservable transitions (with certain

Purinergic Control of Neutrophil Activation [PDF]

open access: yesJournal of Molecular Cell Biology, 2010
Neutrophils constitute the first line of defense against invading pathogens, but they also are responsible for tissue destruction in pathological conditions. In a recent paper published in Science Signaling, Junger and colleagues show that adenosine 5'-triphosphate release and signaling through purinergic P2 receptors upon neutrophil activation by ...

Shimizu–Morioka's chaos synchronization: An efficacy analysis of active control and backstepping methods

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
This research study inspects the effectiveness of synchronization methods such as active control and backstepping control from systematic design procedures of a synchronized Shimizu–Morioka system for the same parameter.

Effect of nettle extract on metabolic processes in piglets during weaning [PDF]

open access: yesKafkas Universitesi Veteriner Fakültesi Dergisi
The article deals with the use of a plant extract to improve metabolic processes and the adaptive capacity of piglets during the weaning period. The study focused on the effects of a 40% ethanolic extract of nettle (Urtica dioica L.) on hematological and
