Vibration isolators are essential in applications like high-precision manufacturing, aerospace, automobiles and sensitive ...

Nature abounds in a diversity of self-assembled materials that are not only structurally complex but often have the ability to dynamically switch between various conformations to perform their ...

Abstract: Electromagnetic negative stiffness springs have been widely used in low-frequency vibration isolation because they can achieve high-static-low-dynamic stiffness (HSLDS) and stiffness control ...

Abstract: In this paper, a novel mechatronic device is introduced for determining the stiffness constant of basic steel tension springs. The device incorporates two measurement principles: ...

Pre-warm-up activities are widely used in sports events to prepare the body for optimum performance (Bishop, 2003). Stretching is usually included as part of the warm-up, but the effect of different ...

The most common studies in the literature are those analyzing fatigue life under cyclic loading for flax fiber-reinforced composites. A novel type of staple fiber yarn made from flax tow with almost ...

Individuals with left ventricular (LV) hypertrophy and elevated cardiac biomarkers in middle age are at increased risk for the development of heart failure with preserved ejection fraction. Prolonged ...

We conducted experiments in which steel and silicon or quartz are clamped together. Even with the smallest tangential forces we could apply, we always found reproducible sliding motions on the ...
