The contribution rate of equipment system-of-systems architecture (ESoSA) is an important index to evaluate the update, development, and optimization. Since traditional ESoSA evaluation method does not make full use fuzzy information uncertain in (ESoS), Bayesian network effective tool solve information, a new based on (FBN) proposed. Firstly, operation loop theory, constructed considering thre...

In this century, medical imaging is at the heart of medical practice. Besides providing fast and accurate diagnosis, advances in radiology equipment offer new and previously non-existing options for treatment guidance with quite low morbidity, resulting in the improvement of health outcomes and quality of life for the patients. Although rapid technological development created new medical imagin...

background: nowadays medical equipment plays an important role in the treatment and in the medical education. using outdated preventive maintenance (pm) system may cause problems in the cutting edge medical equipment, nervous system disease’s equipment (in diagnosis and treatment) which are crucial for every medical center. based on above facts we focused on nervous system treat units’ equipmen...

Both the deformation characters and the failure mode of the large cross-sectional longwall installation roadway under compound roof are becoming an emergent issue than ever before due to the rapid development of modern mining equipment. Various engineering applications have revealed that the insufficient design and inappropriate support technology are the main reasons for the fatal accidents as...

A 38-year-old man had been tetraplegic and ventilator-dependent after sustaining a traumatic cervical spine fracture at the C1/C2 level in 1991, at the age of 22 years. He had been bedbound and mechanically ventilated since then. A multidisciplinary management team approached him in 2003 and helped him to become ambulatory and independent in his daily activities of living. We successfully impla...

The aim of the present study was to verify that the patient/ventilator interaction is similar, regardless of the mode of assisted mechanical ventilation (i.e. pressure- or volume-limited) used, if tidal volume (VT) and peak inspiratory flow (PIF) are matched. Therefore, the authors compared the effects of three different modes of assisted ventilation on the work of breathing (WOB) and gas excha...
