Potential relationships between the structure of the diaphragm and external intercostals and several indices of respiratory muscle function, lung function and nutrition in 27 patients (61+/-10 yrs of age) subjected to thoracotomy as a result of a lung neoplasm have been investigated. Prior to surgery the nutritional status of the patients was assessed and lung function (spirometry, lung volumes...

Dan Port (UHawaii) Vu Nguyen (USc) Tim Menzies (WVU) [email protected], [email protected], [email protected] Jan 19, 2009 ABSTRACT Confidence in cost estimation is different than model accuracy. It is related to the significance of results based on model accuracy measures such as MMRE and PRED. A lack of confidence places uncertainty in the accuracy for predicted values and the conclusions based on ...

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) has defined stage I chronic obstructive pulmonary disease (COPD) as forced expiratory volume in one second/forced vital capacity (FEV1/FVC)% <70% and a FEV1% predicted of >80%. Stage 2 has been defined as FEV1/FVC <70% and a FEV1% pred of <80%. The authors examined the extent of COPD misdiagnosis using this definition in healthy,...

In normal subjects and patients with airway obstruction, flows during a forced vital capacity (FVC) manoeuvre are higher after a fast inspiration without an end-inspiratory pause (manoeuvre 1) as compared to a slow inspiration with an end-expiratory pause of approximately 5 s (manoeuvre 2). In this study, we investigated the influence of these manoeuvres on maximal expiratory volume-time and fl...

The prediction level at x (PRED(x)) and mean magnitude of relative error (MMRE) are measured based on the between real predicted values. They standard metrics that evaluate accurate effort estimates. However, these values might not reveal over-/under-estimation. This study aims to define additional information associated with PRED(x) MMRE help practitioners better interpret those We propose for...

We present an experimental study of the DC breakdown voltage of MEMS interdigitated aluminum electrodes with gaps ranging from 10 to 500 μm. Unlike most research on MEMS electrodes that was done at atmospheric pressure, our work has focused on the effect of gas pressure and gas type on the breakdown voltage. A main goal was to identify geometries that favor the creation of low-voltage discharge...
