Thermodynamic Limits of Work and Pressure Gain in Combustion and Evaporation Processes
Work and Pressure Gain Combustion Evaporation Processes
2014/11/13
Combustion and evaporation processes occurring in a closed chamber can result in significant pressure rise and direct work transfer. The pressure and volumetric changes that accompany such processes a...
Leakage Assessment of Pressure-Exchange Wave Rotors
Pressure-Exchange Wave Rotors Leakage Assessment
2014/11/13
Control of leakage within wave rotors is recognized as a key requirement for efficient operation. Previous studies suggest that experimentally observed performance degradation is substantially due to ...
Normal Pressure Hydrocephalus: A Simple Hypothesis
Normal Pressure Hydrocephalus ApoE3 Head Size Arachnoid Granulations Subpial Absorption
2013/1/31
Normal pressure hydrocephalus is a devious phenomenon. It is a disease that is difficult to diagnose and difficult to treat, the only treatment being a ventriculo-peritoneal shunt, though good shuntin...
Evaluating the effects of open/closed eyes and age-related differences on center of foot pressure sway during stepping at a set tempo
Elderly Dynamic Balance Tempo Stepping Center of Foot Pressure (COP)
2013/1/28
This study aimed to examine the effects of open/ closed eyes and age difference on Center of Foot Pressure (COP) sway during stepping. The subjects were 87 healthy males aged 10 - 80 years. COP was me...
Quantitative analysis of sensor for pressure waveform measurement
sensor pressure waveform measurement
2010/2/25
In this study, we propose a quantitative analysis to evaluate the pressure waveform for locating the position and applying the appropriate force between the sensor and the radial artery. The two-axis ...
Neural set point for the control of arterial pressure: role of the nucleus tractus solitarius
arterial pressure the nucleus tractus solitarius
2010/2/25
Physiological experiments suggest that long-term blood pressure is regulated by the nervous system. The NTS functions as a comparator (evaluating the error signal) between its RNS and the cardiovascul...

Automatic noninvasive measurement of systolic blood pressure using photoplethysmography
Automatic noninvasive measurement systolic blood pressure photoplethysmography
2010/2/25
In this study, we present a cuff-based technique for automatic measurement of systolic blood pressure, based on photoplethysmographic signals measured simultaneously in fingers of both hands. After in...
Artificial arterial blood pressure artifact models and an evaluation of a robust blood pressure and heart rate estimator
Artificial arterial blood pressure a robust blood pressure heart rate estimator
2010/2/25
The KF/SQI-fusion method described in this article was shown to provide an accurate estimate of blood pressure and HR derived from the ABP waveform even in the presence of high levels of persistent no...
Reproducibility and repeatability of measuring the electrical impedance of the pregnant human cervix-the effect of probe size and applied pressure
the electrical impedance the pregnant human cervix-the effect probe size applied pressure
2010/2/25
Measuring cervical resistivity by a single observer with both the 3 and 12 mm probes is highly repeatable whilst inter-observer reproducibility is poor with the 3 mm probe but moderately good when the...
Estimation of Extracellular Volume by Simultaneous Instrumentation of Bioimpedance and Plasma Colloid Osmotic Pressure
bioimpedance colloid osmotic pressure dialysis patient dry weight, extracellular volume
2009/6/9
Extracellular fluid volume can be roughly estimated using the approximate electric resistivity calculated using only the set fluid removal quantity and the measured impedance of each body part in ECUM...
