A Comprehensive Study of the Hydroforming Process of Metallic Bellows: Investigation and Multi-objective Optimization of the Process Parameters
In this paper, for the first time, a comprehensive experimental study is performed on hydroforming process of metallic bellows. For this purpose, the effects of the main process parameters and their interactions on the characteristics of hydroformed metallic bellows are investigated using Response Surface Methodology (RSM). The selected parameters as input variables are internal pressure, die s...
متن کاملWhat is the Bellows Conjecture?
Cauchy’s rigidity theorem states: If P and P’ are combinatorially equivalent convex polyhedra such that the corresponding facets of P and P’ are congruent, then P and P’ are congruent polyhedra. For many years it was unknown whether the same theorem was true in general for non-convex polyhedron. In 1977, more than 160 years after the work of Cauchy, Robert Connelly discovered a polyhedron P (wi...
متن کاملRapid fabrication and characterization of MEMS Parylene C bellows for large deflection applications
We present a rapid, high-yield fabrication process for Parylene C microbellows for large deflection applications and their characterization. Bellows having different convolution number, wall thickness, inner diameter and outer diameter and layer height were fabricated using a lost wax-like process. The effect of design parameters on overall bellows performance was evaluated through load–deflect...
متن کاملEffect of yogic bellows on cardiovascular autonomic reactivity
CONTEXT Yoga is an ancient science, which originated in India. Pranayama has been assigned a very important role in yogic system of exercises. It is known that regular practice of breathing exercises (pranayama) increases parasympathetic tone, decreases sympathetic activity, and improves cardiovascular functions. Different types of breathing exercises alter autonomic balance for good by either ...
متن کاملRestrictive chest bellows disease and frontometaphyseal dysplasia.
We describe a patient with frontometaphyseal dysplasia (FMD), restrictive chest bellows disease, hypercapnic respiratory failure, and cor pulmonale. Treatment with intermittent supplemental oxygen, nocturnal nasal volume ventilation, and posture modification was successful in partial resolution of chronic hypoventilation and excessive daytime somnolence.
