The hub on campus, academic libraries play a significant role in promoting diversity and academic success. Library resources and services have a great impact on university’s recruitment, retention and graduation. This poster session discusses some innovative practices in outreach, effective support in student learning, diverse models in services, and successful approaches in connecting with the campus community.

Show moreHigh Angular Resolution Diffusion Imaging (HARDI) is a powerful extension of Diffusion Tensor Imaging (DTI) capable of resolving intravoxel heterogeneity of fiber orientations which is important for brain connectivity studies. The purpose of this study was to produce a human brain HARDI template by combining information from artifact-free low angular resolution datasets collected on 67 subjects. Show less

Show moreCourse catalog for evening classes in art and design at Abraham Lincoln School (30 West Washington Street, Chicago, Illinois). Class topics were layout and typography, basic design, home planning, and photography, and the classes were taught, at least in part, by students from the Institute of Design, including Mary Henry, Morton Goldsholl, and Jack Waldheim. This catalog is Mary Henry's personal copy, and her inscription on the rear cover reads "While I was a student at the Institute of Design I taught one semester at the Abraham Lincoln School - no salary involved! This is my only copy. M.H." Date of leaflet is unknown, date range indicated is inferred from Mary Henry's dates of attendance at the Institute of Design. Show less

Show moreAn RF measurement system with high time resolution is implemented to determine the statistical characteristics of various channels in the Land Mobile Radio bands. The applicability of simple statistical models to the observed data is investigated, as well as their validity over short and long periods of time. The results show that the statistics of the idle and holding times of communication on these channels vary significantly over time and demonstrate daily periodicity, requiring non-stationary models to accurately represent them. Over short durations of time however, conventional distributions such as the exponential and lognormal may adequately characterize the properties of these quantities, allowing convenient and compact representations of the data. Results based on empirical data are presented to quantify the probability of stationarity for voice traffic within a time span of given length. The findings are useful for network planning or streamlining, network simulation and modeling, and investigation of dynamic spectrum access.
