Biological treatment methods are the basis for waste water treatment worldwide. Among biological treatment systems, activated sludge processes are most widely used to remove the oxygen demand and nutrients from wastewater. The activated sludge process uses naturally occurring bacteria at high concentrations in tanks. The bacteria in the activated sludge process remove small molecules of organic carbon, nitrogen, and phosphate as a consequence of bacterial growth and the waste water is purified. The effluent can then be safely released to the environment. Respirometry techniques are an effective tool to measure the respiration of living organisms. These techniques are associated with …

Optimization Of Microfluidic Particle Separator Geometry Using Computational Fluid Dynamics, Joseph Petersen
Electronic Theses and Dissertations
Computational fluid dynamics software was used to simulate the motion of circulating tumor cells in a variety of microfluidic cell isolation devices. Design of several novel microfluidic cell isolation devices was aided by viewing streamlines of fluid in devices in simulation. Devices that performed best in simulation used 5-micrometer wide guiding channels to guide cells to the capture location in the device. While these devices performed better than other devices in simulation and captured all particles regardless of position along inlet, experimental results differ from simulation.

Service Integration Design Patterns In Microservices, Meng Wang
Electronic Theses and Dissertations
“Microservices” is a new term in software architecture that was defined in 2014 [1]. It is a method to build a software application with a set of small services. Each service has its process to serve a single purpose and communicates with other services through lightweight mechanisms. Because of a great deal of independently distributed services, it is a challenge to integrate the loose services fully. Too many trivial relationships can be messed up easily during deployment. Also, it is hard to modify the relationships if the services are updated as the source codes need to be re-edited and tested. …

Mechanical Bar Splices For Accelerated Construction Of Bridge Columns, Puskar Kumar Dahal
Mechanical Bar Splices For Accelerated Construction Of Bridge Columns, Puskar Kumar Dahal
Electronic Theses and Dissertations
Mechanical bar splicing is an alternative method of connecting reinforcing bars in concrete structures compared to conventional lap splicing mainly to reduce bar congestion in joints. Recently, mechanical bar splices, which are also referred to as bar couplers, have been used to connect precast members to accelerate construction of concrete bridges and buildings. Current codes prohibit the use of couplers in the plastic hinge regions of bridge columns in high seismic zones. This may be because of a lack of systematic test data on the coupler performance, limited experimental studies on mechanically spliced bridge columns, and an engineering precaution. The …
