Energy Consumption And Tardiness Improvement For A Flexible Job Shop And A Warehouse, Ahmad Ebrahimi
Energy Consumption And Tardiness Improvement For A Flexible Job Shop And A Warehouse, Ahmad Ebrahimi
LSU Doctoral Dissertations
In recent years, energy consumption (EC) is studied to see its effects on monetary and non-monetary costs in manufacturing and warehousing. EC in manufacturing and warehousing, however, needs to be studied with conventional performance measures such as production/operation tardiness since there is a trade-off between EC and tardiness costs. Therefore, this research is conducted with four objectives to study EC and tardiness for a flexible job shop and a warehouse as follows. The first objective of this research is to integrate job scheduling and layout, which are interrelated in improving EC and tardiness for a flexible job shop. Thus, we …
A Sustainable Remediation Approach For Complete Destruction Of Chloroethanes In Groundwater, Michael Joseph Cheatham
A Sustainable Remediation Approach For Complete Destruction Of Chloroethanes In Groundwater, Michael Joseph Cheatham
LSU Master's Theses
An up-flow column study was operated in a greenhouse composed of a sand/peat mixed media to investigate the effectiveness of an aerobic zone on the disappearances of chloroethane. The oxygen was supplied by mean of porous Silastic tubing under pressure with a breathing air gas cylinder. Chloroethane was generated via reductive dechlorination of 1,1,1-trichloroethane (TCA) and 1,1-dichloroethane (DCA) in anaerobic bioreactors (ABRs). The columns study was conducted with two duplicate reactors (operated in parallel) that underwent separate perturbations of breathing air introduction. Aqueous samples were collected in 160 mL microcosm bottles and analyzed on a GC equipped with a Flame …
Impact Of Plug-In Electrical Cars On Energy Demand, On Power System And On Environment, Sital Tiwari
Impact Of Plug-In Electrical Cars On Energy Demand, On Power System And On Environment, Sital Tiwari
LSU Master's Theses
The use of an electric vehicle (EV) over a gasoline vehicle (GV) is often portrayed as environment friendly or green movement ignoring how the electricity is produced. EVs get credit for preserving green environment and preventing global warming by minimizing the dependency on oil. Most of the time, these assumptions that favor EV are not well justified. Therefore, proper studies on the impact of electric vehicles on energy demand, on environment and on power system are necessary before reaching to any conclusion. This thesis explores the possibility of energy consumption pattern shift within the different sectors of energy use due …
Working Active Power, Reflected Active Power, And Detrimental Active Power In The Power System, Tracy Nakamura Toups
Working Active Power, Reflected Active Power, And Detrimental Active Power In The Power System, Tracy Nakamura Toups
LSU Master's Theses
Study of decomposition of the active power into components with deeper economical meanings, namely working active power, reflected active power, and detrimental active power is the subject of the thesis. The decomposition of active power will be based on the Current’s Physical Component (CPC) Theory. Working active power is equivalent to useful power that is the rate of energy used to do work, such as mechanical power. Reflected active power is the rate of energy transfer that the load sends back to the supply which dissipates off the supply resistance. This reflected active power is not taken into account on …
