Autonomy and Tuition: State Attempts to Influence Tuition Decisions at Autonomous Public Universities in the State of Michigan

Through analysis of legislation and trends in tuition, enrollment, appropriations and State Consumer Price Index data, the effectiveness of three attempts by state government to control tuition increases by Michigan's constitutionally autonomous public universities are documented with a glimpse at trends for the future. This study attempts to provide an informed analysis of the appropriate data as the effect of the state government's attempts to influence tuition and fills an apparent void in available data on this subject.Master'sCollege of Arts and Sciences: Public AdministrationUniversity of Michiganhttp://deepblue.lib.umich.edu/bitstream/2027.42/117844/1/Mansour.pd

Large-eddy simulation of a turbulent mixing layer

The three dimensional, time dependent (incompressible) vorticity equations were used to simulate numerically the decay of isotropic box turbulence and time developing mixing layers. The vorticity equations were spatially filtered to define the large scale turbulence field, and the subgrid scale turbulence was modeled. A general method was developed to show numerical conservation of momentum, vorticity, and energy. The terms that arise from filtering the equations were treated (for both periodic boundary conditions and no stress boundary conditions) in a fast and accurate way by using fast Fourier transforms. Use of vorticity as the principal variable is shown to produce results equivalent to those obtained by use of the primitive variable equations
