Modeling nonlinear systems using multiple piecewise linear equations [PDF]
, 2010 This paper describes a technique for modeling nonlinear systems using multiple piecewise linear equations. The technique provides a means for linearizing the nonlinear system in such a way as to not limit the large signal behavior of the ...

Development of a Disease Activity Index for the Assessment of VEXAS Syndrome (VEXAS‐DAI)
Arthritis Care &Research, EarlyView.Objective Vacuoles, E1 enzyme, X‐linked, autoinflammatory, somatic syndrome (VEXAS) syndrome is characterized by a complex spectrum of inflammatory and hematologic manifestations. Clinical research to identify effective therapies is urgently needed but is hindered by the lack of validated outcome measures.

Arthritis Care &Research, EarlyView.Objective Youth who experience a sport‐related knee injury have elevated odds of becoming overweight or developing obesity in 3 to 10 years, compounding their risk for posttraumatic osteoarthritis (PTOA). To inform prevention strategies, this study compared patterns of adiposity change between youth with a sport‐related knee injury and uninjured youth ...

Arthritis Care &Research, EarlyView.Objective Despite guideline recommendations, long‐term glucocorticoid (GC) use is common in rheumatoid arthritis (RA). We conducted a clinician survey nested within a large registry to identify patient and clinician factors associated with GC use. Methods Clinicians contributing patients to the CorEvitas Rheumatoid Arthritis Registry were surveyed ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

SUPPLEMENT ON NONLINEAR VIBRATION OF A SMALL-SAG CABLE SUBJECTED TO AN AXIAL TIME-VARYING LOAD AND TRANSVERSE TIME-VARYINGLOAD [PDF]
, 1997 本研究は, 周期的変動軸力 (係数励振力) と面内周期的変動荷重を同時に受ける偏平ケーブルの非線形振動に及ぼす, 周期的変動軸力と面内周期的変動荷重間の加振振動数比の影響および過渡振動の影響を評価したものである. これより, 加振振動数比は, ケーブルの分岐応答および主共振の応答に影響を及ぼすことを明らかにした. さらに, 平均法による過渡振動の解析の精度は良好で, 過渡振動の振幅は定常振動の約1.5倍になることを示した.Nonlinear dynamic response of a suspended
