a dissolved methane sensor based on silicone tube was designed, constructed and optimized.the silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.a continuous stream of helium (50 ml/min) was directed through the tubing, sweeping out the dissolved methane which diffused through the walls of the tubing from t...
In static load tests vibrating wire strain gages are generally used. The advantage of vibrating wire sensors over more conventional electrical resistance or semi-conductor types lies mainly in the sensor output, which is a frequency rather than a voltage or resistance. The frequency output is easier to transmit over long cables and is unaffected by voltage drops such as those which can be broug...
this paper presents density functional theory and non-equilibrium green’s function based first principles calculations to explore the sensing property of adenine and thymine based hetero-junction chins for ammonia and phosphine gas molecules. this modeling and simulation technique plays an important and crucial role in the fast growing semiconductor based nanotechnology field. the hetero-juncti...
Conductor galloping may cause flashovers and even tower collapses. The available conductor galloping monitoring methods often employ acceleration sensors to measure the conductor translations without considering the conductor twist. In this paper, a new sensor for monitoring conductor galloping of transmission lines based on an inertial measurement unit and wireless communication is proposed. A...
introduction: delivering maximum dose to tumor and minimum dose to normal tissues is the most important goal in radiotherapy. according to icru, the maximum acceptable uncertainty in the delivered dose compared to the prescribed dose should be lower than 5%, and this is because of the relationship between absorbed dose, tumor control and normal tissue damage. absorbed dose accuracy is investiga...
The automotive electronics has been introduced with multiple waves over the time: powertrain, safety & vehicle dynamic, body & convenience, telematics. The future is already knocking at the door and revolutionary systems are currently developed: X-by-wire, E-safety, Hybrid vehicle. The increasing requirements for fuel economy, safety, emission reduction, and onboard diagnosis push the automotiv...
