The Phillips curve has flattened out over the last decades. We develop a model that rationalizes this phenomenon as result of observed increase in polarization many industries, process along which few top firms gain an increasing share their industry market. In model, compete la Bertrand and there is exit endogenous market entry, well optimal up downgrading technology. Firms with larger shares ...

Polyurethane foams have unique properties that make them suitable for a wide range of applications, including cushioning and seat pads. The foam mechanical largely depend on both the parent material cell microstructure. Uniaxial loading experiments, X-ray tomography finite element analysis can be used to investigate relationship between macroscopic microscopic structure. specimens were scanned ...

Impact loading is a major factor in the high prevalence of musculoskeletal injuries among military personnel during operational tasks. One of the therapeutic purposes of a pedorthic approach is to attenuate impact load through footwear and supportive device cushioning. The following research pilot project attempts to investigate this relationship. Vertical acceleration was collected at the four...

In many applications, one needs to combine materials with varying properties to achieve certain functionalities. For example, the inner layer of a helmet should be soft for cushioning while the outer shell should be rigid to provide protection. Over time, these combined materials either separate or wear and tear, risking the exposure of an undesired material property. This work presents a desig...
