DRIFT POTENTIAL FOR LOW PRESSURE EXTERNAL MIXING TWIN FLUID NOZZLES BASED ON WIND TUNNEL MEASURMENTS
در این پایان نامه، به کمک نرم افزار flow-3d میدان جریان عبوری از سریز اوجی بررسی می گردد. همچنین اثر هندسه سرریز و بلندای آب بالا دست سرریز بر میدان جریان و توزیع فشار بررسی شده و تاثیر مدل های مختلف آشفتگی (renormalizd group) rng, k-e, prandtl در میدان جریان نیز مورد توجه بوده است. نرم افزار flow-3d یک برنامه تحلیلی میدان جریان است که معادلات حاکم بر میدان جریان عبوری از روی سرریز که همان معاد...
Background. Exposure to prenatal inflammation increases the risk for development of bronchopulmonary dysplasia. Aim. To evaluate the correlation between cord blood and gastric aspirate levels of interleukine-6 (IL-6) and interleukine-8 (IL-8) in preterm infants, and lung function at the age of 8 years. Methods. Between 2000-2002 we recruited 129 infants of gestational age < 30 wks. The concentr...
In this paper, we present a new system to segment and label CT Brain slices using diierential geometrical invariant features and unsupervised clustering. Our aim is to extract reliable and robust measures from CT images of Traumatic Brain Injury (TBI) patients that can accurately describe the morphological changes in the brain as recovery progresses, and to study the correlation between the mor...
Standard medical diagnosis requires attaching sensors or electrodes to the patient and then connecting these electrodes to bulky equipment powered by mains supply. This is usually an acceptable procedure for short term patient monitoring. However, for long term monitoring, this approach is neither comfortable nor durable. Therefore considering fully implantable electronic systems which have man...
Two kinds of microporous activated nanostructured carbons were studied by electron paramagnetic resonance (EPR) spectroscopy. They have different specific surface areas: 1500 m2/g (AC I) and 2500 m2/g (AC II). It was observed that the EPR spectra shapes and their temperature evolution between 300 K and 4 K were depending on the types of carbon sample. Roomtemperature spectra show dissimilar lin...
