On An Iterative Method For Basis Pursuit With Application To Echo Cancellation With Sparse Impulse Responses, Pratik Shah, Steven L. Grant, Jacob Benesty

Electrical and Computer Engineering Faculty Research & Creative Works

Basis pursuit has been shown to be an effective method of solving inverse problems with a small amount of data when the system to be determined has a sparse representation. Adaptive filters fall under this general category of problems. Here, we use the echo cancellation context to introduce a method of solving the basis pursuit problem with an iterative method based on the proportionate normalized affine projection algorithm (PAPA). Earlier, it has been shown that PAPA can be derived from a basis pursuit perspective. Here we refine the assumptions made in those derivations and show that an iterative form of …

Wetland And Riparian Management Plan, Alcalde/Velarde Valley, Upper Rio Grande, New Mexico, Jessica C. Johnston

Water Resources Professional Project Reports

In New Mexico, riverine wetlands are generally associated with riparian areas found in the floodplains or once floodplains, of the Rio Grande and associated tributaries. Riverine wetlands are supported with water provided by over bank flow from the river, connection to the shallow groundwater, and/or acequia systems. Wetland and riparian areas are impacted by land uses, hydromodification and other activities that occur within a watershed. Wetland and riparian areas play an important role within a watershed by providing many beneficial environmental functions. This paper examines watershed issues affecting the quality of remaining wetland and riparian resources in the valley and …

Clean Energy: The Economics Of Why And How, Adele C. Morris

Brookings Scholar Lecture Series

One rationale for large public investments in clean energy technology points to concerns that have not been addressed by other policies, most notably greenhouse gas emissions and energy security. Another inspiration for clean energy policy suggests that strategic government investments would increase domestic firms' market share of a growing industry and thus help domestic firms and workers. This lecture examines the economic case for clean energy policy in the United States and addresses the issues state and local governments confront in building a clean energy industry.

Near-Field 3-D Synthetic Aperture Radar Imaging Via Compressed Sensing, Zengli Yang, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

This paper successfully implements compressed sensing (CS) to a near-field wideband 3-D synthetic aperture radar (SAR) imaging system. SAR data are measured at a low percentage of random-selected positions on a uniform grid of planar aperture in the strip map mode. the near-field 3-D range migration algorithm (RMA) is used in combination with the CS principle to reconstruct the 3-D image via l 1 regularized least-square approach. Experiments were performed with Q-band stepped-frequency monostatic strip map SAR imaging system on a blue foam embedded with eight rubber pads and one copper square chip. the results of the experiments show near-field …

Effect Of Frequency Oversampling And Cascade Initialization On Permutation Control In Frequency Domain Bss, Christopher Osterwise, Steven L. Grant

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a new algorithm for addressing the permutation ambiguity in convolutive blind source separation. the proposed algorithm seeks to prevent permutations by frequency oversampling, and then exploiting the induced correlation between bins. Any remaining permutation is then corrected by beam pattern estimation. Cascade initialization is shown to improve system performance while decreasing processing time, while frequency oversampling is shown to increase performance with slight increases in computational time. the algorithm is proven robust against isotropic noise, producing an SIR improvement of 12.9 dB when the reverberation time is 260 ms, and the signals at the input are only …

Assessing Eli Broad's Assault On Public School System Leadership. A Response To "The Broad Challenge To Democratic Leadership: The Other Crisis In Education.", Fenwick W. English, Zan Crowder

Democracy & Education

Eli Broad’s approach to reforming urban public education does not recognize his own self-interest in promoting changes within such educational systems, a classic problem of misrecognition. The Broad agenda is an assault on the notion of the mission of public education as a service instead of a for-profit enterprise concerned with making money for the owners and stock holders. This article examines the backgrounds of the graduates of the Broad Superintendents Academy and raises critical issues such as how can Broad claim that graduate preparation in educational administration is unnecessary when at least half of his own graduates already have …

Charitable Organizations And Commercial Activity: A New Era - Will The Social Entrepreneurship Movement Force Change?, Jaclyn Cherry

The Journal of Business, Entrepreneurship & the Law

It is no longer a new trend for charitable organizations to become involved in commercial activities. Thousands of nonprofit organizations have embraced the social entrepreneurial concept and have either created “commercial” type ventures as part of their nonprofits, have created spin-off organizations or subsidiary organizations, or have moved into the new area of hybrid organizations. Because there are no clear rules or guidelines for dealing with this issue, the third sector finds itself with rogue components and a spin-off group of hybrid organizations being loosely termed “social entrepreneurs.” Though these groups have grown in numbers in recent years, they have …

Academic Library Services To Distance Learners: In Consideration Of Costs, Technology, And Stability, Christopher Diaz

Urban Library Journal

In the last fifteen years, there has been an increase in the implementation of distance education programs in colleges and universities. The challenge for academic libraries will be to create working models of library support for distance learners that are both economically sustainable, and qualitatively equitable to the support given to on-campus students. The author suggests that training in advanced web computing and educational technologies must begin in the graduate study of library and information science to help offset the training costs for academic libraries. One solution might include utilizing networks of distance students to create business and other partnerships …

The New Distance Learners: Providing Customized Online Research Assistance To Urban Students On The Go, Melissa N. Mallon

Urban Library Journal

This article provides an overview of the pedagogical theories surrounding distance learning while discussing the learning styles and characteristics of distance learners. The author describes how the use of social media and learning objects supports the pedagogical theory of connectivism. The author discusses how a mid-sized, urban university library uses social media tools, including YouTube and Twitter, to offer distance learning students the same level of research support as those studying on campus while examining other libraries that do the same. This method provides students with the opportunity to pick and choose online research support that is customized to their …

Time Zones, Screencasts, And Becoming Real: Lessons Learned As A Distance Librarian, Rebecca Hedreen

Urban Library Journal

The library literature abounds with articles, presentations, and books on using various sorts of distance learning tools and techniques for library services. (I direct you to the excellent 5th Bibliography of Library Services for Distance Learning Resources from the Distance Learning Section of ACRL or practically any library conference proceedings for numerous examples.) Many of those resources will discuss how a particular type of tool, say, webchat, can be used for library services, with examples of successful, and sometimes unsuccessful, use in various types of libraries. I have, however, very rarely seen any discussion of when to use such tools, …
