Urban Growth, Community, and the Environment: An Experiential Pedagogy

Some scholars have described urban sprawl as America\u27s most pressing environmental issue. As educators we are acutely interested in unearthing new methods for engaging students in these types of topics. In this paper we describe a unique interdisciplinary and experiential course that we have designed to introduce students of various academic programs to the attendant issues of urban sprawl

Improving the Resolution of Bearing in Passive Sonar Arrays by Eigenvalue Analysis

Tech ReportA method of improving the bearing-resolving capabilities of a passive array is discussed. This method is an adaptive beamforming method, having many similarities to the minimum energy approach. The evaluation of energy in each steered beam is preceded by an eigenvalue-eigenvector analysis of the emperical correlation matrix. Modification of the computations according to the eigenvalue structure result in improved resolution of the bearing of acoustic sources. The increase in resolution is related to the time-bandwidth product of the computation of the correlation matrix. However, this increased resolution is obtained at the expense of array gain
