Passivity-based control of saturated induction motors

IEEE Transactions on Industrial Electronics, 2001
A passivity-based controller, which takes into account saturation of the magnetic material in the main flux path of the induction motor, is developed to provide close tracking of time-varying speed and flux trajectories in the high magnetic saturation regions. The proposed passivity based controller is experimentally verified.

Improving Saturation-based Bounded Model Checking

Acta Cybernetica, 2016
Formal verification is becoming a fundamental step in assuring thecorrectness of safety-critical systems. Since these systems are oftenasynchronous and even distributed, their verification requires methodsthat can deal with huge or even infinite state spaces.

Improved MPC Design based on Saturating Control Laws* [PDF]

European Journal of Control, 2003
This paper is concerned with the design of stabilizing model predictive control (MPC) laws for constrained linear systems. This is achieved by obtaining a suitable terminal cost and terminal constraint using a saturating control law as local controller.

Reversal of Forest Soil Acidification in the Northeastern United States and Eastern Canada: Site and Soil Factors Contributing to Recovery

Soil Systems, 2020
As acidic deposition has decreased across Eastern North America, forest soils at some sites are beginning to show reversal of soil acidification. However, the degree of recovery appears to vary and is not fully explained by deposition declines alone.

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Reductions and Saturation Reductions of (Abstract) Knowledge Bases

Electronic Notes in Theoretical Computer Science, 2014
AbstractRough set theory is a useful tool for dealing with fuzzyness and uncertainty of knowledge. In rough set theory, knowledge reductions and generatings are important research topics and critical steps of knowledge acquisition. This paper generalize knowledge bases to abstract knowledge bases and study (abstract) knowledge bases on infinite ...

Safety of Daprodustat for the Treatment of Chronic Kidney Disease Anemia: Final Analysis of a Multicenter Postmarketing Surveillance Study in Japan

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This final analysis of a multicenter, prospective postmarketing surveillance study evaluated the safety of daprodustat in patients with chronic kidney disease anemia in routine clinical practice in Japan. Methods Patients who initiated daprodustat between September 2020 and July 2022 were registered.

Relações entre os tipos e indicadores de acidez do solo em lavouras no sistema plantio direto na região do Planalto do Rio Grande do Sul Relationships among acidity types and indicators in soils under no-tillage system in the Rio Grande do Sul Planalto Region

Revista Brasileira de Ciência do Solo, 2008
A recente mudança no sistema de cultivo do solo ocorrida no Brasil, passando do preparo convencional (PC) para o sistema plantio direto (SPD), altera o funcionamento do solo. No solo cultivado no SPD, as relações se estabelecem no tempo e são preservadas
