Summary: Reset controllers have the potential to improve the performance of high-precision industrial motion systems. However, analyzing the stability of these controllers is complex and requires the parametric model of the system, which may limit their applicability. This paper proposes a frequency-domain approach to assess the stability properties of control systems with first and second-order reset elements. The proposed approach can also determine the uniformly bounded-input bounded-state (UBIBS) property for reset control systems when resetting to non-zero values. An illustrative example is provided to demonstrate the effectiveness of using frequency response measurements to assess the stability properties of reset control systems.

Summary: This article presents a novel design of a vortex chamber with axial grooves for cooling the leading edge of turbine blades. The chamber generates a vortex through nine tangential inlets and includes an axial groove. The grooves enhance flow turbulence and increase heat transfer by disrupting the thermal boundary layer. Using a 3D model based on the Reynolds-averaged Navier-Stokes equation, different turbulent models and experimental data were compared, with the Reynolds stress model (RSM) showing the highest accuracy. Various groove sizes, positions, and numbers were examined to study the vortex structure and heat transfer mechanism. The results revealed improved heat transfer in the chamber with grooves, especially with three grooves resulting in an average Nusselt number increase of over 4%. The pressure difference between chambers with and without grooves was not significant, but the highest friction factor occurred in the case with three grooves.

The hybrid nanomaterial consisted of a mixture of Al2O3 and CuO with a volume fraction of 0.01 for each powder type, making the homogeneous mixture approximation logical. A wiremesh packed approach was used to model the porous foam, and the impact of porosity on the freezing process was analyzed. The temperature equation, including two source terms for radiation and phase changing, was considered, and the Galerkin method was implemented for solving the equations.

Summary: Arterio-venous grafts (AVGs) are commonly used for long-term vascular access in hemodialysis. Intimal hyperplasia (IH) caused by unfavorable hemodynamic conditions is the main reason for AVG failure. This study utilizes computational fluid dynamics (CFD) to assess the impact of different geometrical designs on the hemodynamic conditions at the venous anastomosis. The results show that optimizing the anastomosis angle and introducing cross-sectional ridges in the graft can significantly reduce the risk of IH development.

Summary: Higher-order elasticity theories are used to model mechanics at the nanoscale, but the length-scale parameters in these theories need to be evaluated through experiments or MD simulations. This study shows that the length-scale parameter in the modified strain gradient theory varies with dimensions, boundary conditions, and deformation level for carbon and boron nitride nanotubes. To address this issue, a supervised ML-based framework is developed, combining MD simulations, continuum formulation, and ML to predict the length-scale parameter for a given material, dimension, and boundary condition. This predictive tool reduces the need for expensive MD simulations and opens up possibilities for applying non-classical continuum theories to nanoscale mechanics problems.

Summary: The motion of a rigid body, described by Euler's equations in Classical Mechanics, assumes that the distances between constituent particles are fixed. However, real bodies cannot meet this assumption due to thermal fluctuations. In order to incorporate dissipative and thermal fluctuation effects into the description, a generalization of Euler's equations is proposed. This theory explains the origin of these effects as internal, rather than caused by an external thermal bath, and derives the stochastic differential equations governing the body's orientation and central moments.
