A robust fixed point transformation-based approach for type 1 diabetes control [0.03%]
一种用于1型糖尿病控制的鲁棒固定点变换方法
Levente Kovács
Levente Kovács
Modeling and control of diabetes mellitus (DM) are difficult due to the highly nonlinear attitude, time-delay effects, the impulse kind input signals and the lack of continuously available blood glucose (BG) level to be regulated. Regarding...
A comparative study of the vibro-impact capsule systems with one-sided and two-sided constraints [0.03%]
单侧和双侧约束振动胶囊系统比较研究
Yao Yan,Yang Liu,Maolin Liao
Yao Yan
This paper studies the dynamics of the vibro-impact capsule systems with one-sided and two-sided soft constraints under variations of various system and control parameters, including mass ratio, stiffness ratio, gap of contact, and amplitud...
Numerical and experimental studies of stick-slip oscillations in drill-strings [0.03%]
钻柱中粘滑振荡的数值和实验研究
Yang Liu,Joseph Páez Chávez,Rulston De Sa et al.
Yang Liu et al.
The cyclic nature of the stick-slip phenomenon may cause catastrophic failures in drill-strings or at the very least could lead to the wear of expensive equipment. Therefore, it is important to study the drilling parameters which can lead t...
Nonsmooth analysis of three-dimensional slipping and rolling in the presence of dry friction [0.03%]
干摩擦存在下的三维滑动和滚动的非光滑分析
Mate Antali,Gabor Stepan
Mate Antali
In this paper, the nonsmooth dynamics of two contacting rigid bodies is analysed in the presence of dry friction. In three dimensions, slipping can occur in continuously many directions. Then, the Coulomb friction model leads to a system of...
Nonlinear stability analysis of whirl flutter in a rotor-nacelle system [0.03%]
旋翼整流罩系统中挥舞 flutter 的非线性稳定性分析
Christopher Mair,Djamel Rezgui,Branislav Titurus
Christopher Mair
Whirl flutter is an aeroelastic instability that affects propellers/rotors and the surrounding airframe structure on which they are mounted. Whirl flutter analysis gets progressively more complicated with the addition of nonlinear effects. ...
On boundary damping to reduce the rain-wind oscillations of an inclined cable with small bending stiffness [0.03%]
边界阻尼在小弯曲刚度倾斜缆索雨风振动控制中的应用研究
Tugce Akkaya,Wim T van Horssen
Tugce Akkaya
In this paper, a model will be derived to describe the rain-wind-induced oscillations of an inclined cable. Water rivulets running along the cable and aerodynamics forces acting on the cable are taken into account to describe these oscillat...
Comparing the direct normal form and multiple scales methods through frequency detuning [0.03%]
通过频率偏移比较直接正规形式和多重尺度方法
A J Elliott,A Cammarano,S A Neild et al.
A J Elliott et al.
Approximate analytical methods, such as the multiple scales (MS) and direct normal form (DNF) techniques, have been used extensively for investigating nonlinear mechanical structures, due to their ability to offer insight into the system dy...
Comments on "Coexistence of hidden chaotic attractors in a novel no-equilibrium system" (Nonlinear Dyn, doi:10.1007/s11071-016-3170-x) [0.03%]

In this comment, an enhancement of issue published in the paper "Coexistence of hidden chaotic attractors in a novel no-equilibrium system" (Nonlinear Dyn, doi:10.1007/s11071-016-3170-x) is addressed. We have shown that the proposed novel a...
On the rotational equations of motion in rigid body dynamics when using Euler parameters [0.03%]
基于Euler参数的刚体动力学转动运动方程研究
Karim Sherif,Karin Nachbagauer,Wolfgang Steiner
Karim Sherif
Many models of three-dimensional rigid body dynamics employ Euler parameters as rotational coordinates. Since the four Euler parameters are not independent, one has to consider the quaternion constraint in the equations of motion. This is u...

A fractional wave equation replaces the second time derivative by a Caputo derivative of order between one and two. In this paper, we show that the fractional wave equation governs a stochastic model for wave propagation, with deterministic...
