A Study on Zero Sensitive Control System

open access: yesIEEJ Transactions on Electronics, Information and Systems, 2009
Since system uncertainties are unavoidable in the modeling, control systems are generally required to be insensitive to these uncertainties. In this paper, the problem of control system design which is insensitive to these uncertainties is studied, and a structure of system uncertainties which do not affect the control performance is clarified.

Stack structured hybrid load cell for a high-stroke system

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2019
The load cell is an essential sensor for the force measurement systems. The sensitivity of a typical load cell for general force measurement is constant over the full operating range.

A Real-Time Adaptive Control System for Border Irrigation

open access: yesAgronomy, 2022
The shortage of water resources makes it urgent to increase agricultural irrigation efficiency. In response to this need, this study develops a real-time adaptive control irrigation (RACI) system for border irrigation.

Invariant set theory for predicting potential failure of antibiotic cycling

open access: yesInfectious Disease Modelling
Collateral sensitivity, where resistance to one drug confers heightened sensitivity to another, offers a promising strategy for combating antimicrobial resistance, yet predicting resultant evolutionary dynamics remains a significant challenge. We propose

An integrodifferential approach to modeling, control, state estimation and optimization for heat transfer systems

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2016
In this paper, control-oriented modeling approaches are presented for distributed parameter systems. These systems, which are in the focus of this contribution, are assumed to be described by suitable partial differential equations.

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

open access: yesPopulation Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Robustness Analysis of a Class of Optimal Control Systems [PDF]

open access: yesModeling, Identification and Control, 1983
This paper deals with a class of optimal control systems, where the controller. in addition to minimizing a quadratic criterion, also shall give the closed-loop system prescribed eigenvalues.

Increased pain sensitivity in low blood pressure. [PDF]

open access: yes, 2008
. There is broad evidence for a functional interaction between the cardiovascular and pain regulatory systems. One result of this interaction is the reduced sensitivity to acute pain in individuals with elevated blood pressure, which has been established

FoxO1 signaling in B cell malignancies and its therapeutic targeting

open access: yesFEBS Letters, EarlyView.
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

Quantification and Mitigation of Unfairness in Active Power Curtailment of Rooftop Photovoltaic Systems Using Sensitivity Based Coordinated Control

open access: yesEnergies, 2016
With increasing photovoltaic (PV) penetration in low voltage networks (LVNs), voltage regulation is a challenge. Active power curtailment (APC) is one possible solution for mitigating over voltages resulting from active power injection in LVNs.
