The Application of Ultrasonic Waves for Determining the Liquid Level in Reactor for Monitoring a Process Reactor
, M.Sc. Thesis Sharif University of Technology ; Hajsadeghi, Khosrow (Supervisor)
Abstract
In this research non-contact ultrasonic based method is used for liquid level measurement in a container. A system has been designed and developed to determine the liquid level and show the results on a personal computer. The system contains three main parts, which are mechanical and electronic parts and the programming. The setup can measure the liquid level with the accuracy of 1cm. An ATMEGA8 microprocessor commands to relays and controls the pumps. The pumps are used to change the height of the liquid in the containers to accurately calibrate the sensor and test its operation. The ultrasonic sensor, which is mounted above the vessel, transfers the data to an ATMEGA64 microprocessor for...
Reservoir Reoperation for the Uncertain Future
, M.Sc. Thesis Sharif University of Technology ; Abrishamchi, Ahmad (Supervisor)
Abstract
Little research has been conducted on the topic of water resources management in case of deep uncertainty. It is vital for the management method to be upgraded in order to accompany future changes. The purpose of this study is to inspect some viable scenarios and deriving proper reservoir management solutions in case of deep uncertainty. This is important due to the fact that future changes are often not considered when water resources structured are being designed. In the past, some researches in this field of study were done; For instance, the effects of climate change on reservoirs have been assessed. Also methods for coming up with scenarios have been proposed, most of which are based on...
