Based on the aeroengine lubricating oil system test bench, this paper used a dimensional analysis method to establish mathematical model for predicting separation efficiency and resistance of dynamic pressure oil-air separator suitable engineering. The multivariate nonlinear fitting error experimental data showed that established could accurately predict performance within certain range; averag...

Rectal manometry provide a useful method to objectively assess the physiology of defecation. We developed a probe with 10 embedded transducers for evaluating the dynamic rectal pressure profile. The innovation of the probe is to use small piezoresistive dice and reduce the packaging resulting in a very small assembly. The diameter of the probe is 9 mm with a length of 20 cm. The length could be...

In the present paper, a mathematical model is used in order to predict the longitudinal distribution of dynamic pressure on planing hulls. The present model is based on the empirical equations resulted from multitude of experiments that have been carried out over the years on planing boats. These empirical equations are able to predict a longitudinal section of the pressure distribution. The ob...

Assessment of vasomotor tone is essential in defining appropriate resuscitation strategies for the hypotensive patient. Although changes in mean arterial pressure to cardiac output define arterial resistance, resistance is only one component of vasomotor tone. Compliance is the other component. The reciprocal of compliance is arterial elastance (Ea). Importantly, dynamic Ea can be estimated by ...

Wrist pulse analysis for identification of health status is found in Ancient Indian as well as Chinese literature. The preprocessing of wrist pulse is necessary to remove outlier pulses and fluctuations prior to the analysis of pulse pressure signal. This paper discusses the identification of irregular pulses present in the pulse series and intricacies associated with the extraction of time dom...

Epidemiological studies suggest an inverse relationship between physical activity or fitness and blood pressure. In controlled intervention studies, the weighted net change in conventional blood pressure caused by dynamic aerobic training averaged -5.3 mmHg for systolic and -4.8 mmHg for diastolic blood pressure. The considerable interstudy variation in the blood pressure response can be partly...

Reducing blood flow to working muscles during dynamic exercise causes metabolites to accumulate within the active muscles and evokes systemic pressor responses. Whether a similar cardiovascular response is elicited with normal blood flow to exercising muscles during dynamic exercise remains unknown, however. To address that issue, we tested whether cardiovascular responses are affected by incre...
