Steering drift and wheel movement during braking: static and dynamic measurements
YesThis paper reports on an experimental investigation into braking-related steering drift in
motor vehicles, and follows on from a previous paper by the authors in which it was concluded that
braking can cause changes in wheel alignment that in turn affect the toe-steer characteristics of each
wheel and therefore the straight-line stability of the vehicle during braking. Changes in suspension
geometry during braking, their magnitude and the relationships between the braking forces and the
suspension geometry and compliance are further investigated in an experimental study of wheel
movement arising from compliance in the front suspension and the steering system of a passenger
car during braking. Using a kinematic and compliance (K&C) test rig, movement of the front wheels
and the suspension subframe, together with corresponding changes in suspension and steering
geometry under simulated braking conditions, have been measured and compared with dynamic
measurements of the centre points of the front wheels. The results have enabled the causes and effects
of steering drift during braking to be better understood in the design of front suspension systems for
vehicle stability during braking

Wheel movement during braking
YesAn experimental study of wheel movement arising from compliance in the front suspension and
steering system of a passenger car during braking is presented. Using a Kinematic and
Compliance (K&C) test rig, movement of the front wheels and the suspension sub-frame,
together with corresponding changes in suspension / steering geometry under simulated braking
conditions, were measured and compared with dynamic measurements of the centre points of the
front wheels. The resulting knowledge of front wheel deflections has enabled the causes and
effects of steering drift during braking to be better understood in the design of front suspension
systems for vehicle stability
State Estimates of Employment Rates for Persons with Disabilities: Report Summary
Statistics on the states’ employment rates for persons with disabilities relative to their non-disabled peers may be of assistance to providers of employment services for persons with disabilities. Such information can help service providers, policy makers, and disability advocacy leaders to assess whether the employment rate of people with disabilities is improving over time, given policy, regulatory, and service intervention strategies.
A recent report from the Cornell University Rehabilitation Research and Training Center (RRTC) for Economic Research on Employment Policy for Persons with Disabilities uses data from the March Current Population Survey to estimate employment rates for persons with and without a disability in the non-institutionalized working-age (aged 25 through 61) civilian population in the United States, and for each state and the District of Columbia for the years 1980 through 1998. The employment rate of persons with a disability relative to that of persons without disabilities are found to vary greatly across states. Over the last 20 years the relative employment rate of those with a disability dramatically declined overall and in most states
Economics of Disability Research Report #3: Estimates of Median Household Size-Adjusted Income for Persons with Disabilities in the United States by State, 1980 through 1998
This report uses data from the March Current Population Survey to estimate median household size-adjusted income for persons with and without a disability in the non-institutionalized working-age (aged 25 through 61) civilian population in the United States, and for each state and the District of Columbia for the years 1980 through 1998. The median household size-adjusted income of persons with a disability relative to those of persons without a disability varies greatly across states. Since 1980, however, the growth in the median household size-adjusted income of those with a disability has fallen below that of the rest of the working population overall and in the vast majority of states
Searches for Compositeness at the Tevatron
Quark-quark and quark-lepton searches for compositenss at the Fermilab
Tevatron are summarized. These are of the contact-interaction variety where
sqrt(s-hat) < the hypothesized mass scales, Lambda. Tevatron experiments limit
a variety of compositeness phenomena in the range from 1.9 to 8.3 TeV. These
limits result from measurements of: the Ht spectrum (D0), dijet mass (D0),
dijet angular distribution (CDF, D0), drell-yan production (CDF, D0), and the
Neutral Current to Charged Current ratio (CCFR/NuTeV).Comment: Presented at VIIIth RENCONTRES DE BLOIS, with recent updates added. 7
