Extracorporeal membrane oxygenation (ECMO) is increasingly implemented in patients with end-stage pulmonary disease as a bridge to lung transplant. Several centers have instituted an approach that involves physical rehabilitation and ambulation for patients supported with ECMO. Recent reports describe the successful use of ambulatory ECMO in patients with chronic respiratory illnesses being bri...

A methodology for the design of compact transformers operating at high frequency is presented in this article. particular emphasis paid to thermal management magnetic core and winding components. For a 7 kW dual active bridge dc–dc converter, objective reduce volume (<80 cm 3 ), improve power ef...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...

Learning from failures made along the product life cycle is an effective way for enterprises to increase product and service quality and decrease costs at the same time. However, the product life cycle is distributed in time and space and therefore the implementation of organizational learning processes have to bridge informational, conceptual and technological barriers. The organizational memo...

scour around bridge piers is one of the most important fields of hydraulic research. local scour around bridge piers and abutment is one of the main reasons of bridge failures. in the field of scour at the bridges, researches are more focus on scour of piers in compare with abutment. while the available information on the bridge failures required cost, the major problems are related to abutment...
