Meet USC: Admission Presentation, Campus Tour, & Engineering Talk
Fri, Dec 04, 2009
Viterbi School of Engineering Undergraduate Admission
Workshops & Infosessions
This half day program is designed for prospective freshmen and family members. Meet USC includes an information session on the University and the Admission process; a student led walking tour of campus and a meeting with us in the Viterbi School. Meet USC is designed to answer all of your questions about USC, the application process and financial aid.Reservations are required for Meet USC. This program occurs twice, once at 9:00 a.m. and again at 12:00 p.m. Please visit http://www.usc.edu/admission/undergraduate/visit/meet_usc.html to check availability and make an appointment. Be sure to list an Engineering major as your "intended major" on the webform!

TMDL Development and Trash TMDLs
Fri, Dec 04, 2009 @ 12:45 PM - 01:45 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker: Eric Wu, Ph.D., P.E., Unit Chief, Total Maximum Daily Load (TMDL) Unit,
Los Angeles Regional Water Quality Control BoardAbstract:The Clean Water Act (CWA) requires USEPA and States to identify waters that do not meet water quality standards, and to develop total maximum daily loads (TMDLs) for each impaired waterbody. The development of a TMDL is a regulatory procedure to amend the Los Angeles Region Water Quality Control Plan (Basin Plan). The required documents include a Staff Report, Resolution, Basin Plan Amendment, and a Substitute Environmental Document (SED). A TMDL becomes effective after the USEPA approves it. Up to date, approximately 35 TMDLs were developed to address pollutants such as bacteria, metals, pesticides, nutrients, toxicity and trash in multiple watersheds.Location: Kaprielian Hall (KAP) - 209

Attitude Control and Fuel Slosh: Implications for NASAâ€s Constellation Program
Fri, Dec 04, 2009 @ 02:00 PM - 03:00 PM
Astronautical Engineering
Conferences, Lectures, & Seminars
Attitude dynamics is the modeling of spacecraft orientation based on the conservation of angular momentum, accounting for external torques. This investigation considers the effect of the sloshing motion in liquid fuel tanks, the corresponding torque it imparts on space vehicles, and the subsequent effect on spacecraft attitude. Depending on the mission, this liquid motion can impose significant vehicle design constraints. For NASA's Constellation Program, the baseline propellant budget for the Altair Lunar Lander includes a significant mass allocation to compensate for slosh disturbances. In this investigation, in order to alleviate these guidance and navigation design constraints, we consider methods to minimize this fluid motion by altering fluid properties. A two pronged approach is initiated. First, we will perform a series of experiments using an existing test bed at the Southwest Research Institute (SwRI) in San Antonio, TX. SwRI is internationally recognized for its fuel slosh expertise; their experiments and analysis have been used to validate launch vehicle and spacecraft designs.Second, we will create a computational test bed. Two essential components will be developed separately, using commercial software packages. A computational fluid dynamics problem solver (Fluent) will model surface disturbances and internal fluid motion in a partially filled liquid tank and compute the corresponding hydrodynamic forces exerted by the fluid on the interior of the tank surface. A separate program (Matlab Simulink) will simulate spacecraft attitude, implementing spacecraft control algorithms. Disturbance torques as characterized by the Fluent model will be an input to Matlab, providing a direct correlation between liquid motion and spacecraft attitude.
