A Dual-Mode Programmable Distributed Amplifier/Mixer, Laleh Rabieirad, Saeed Mohammadi

Department of Electrical and Computer Engineering Faculty Publications

A dual-mode field programmable RF amplifier / mixer is presented. Transistor switches, low loss CPW lines and RF transistors are combined in a 3-stage distributed topology which can operate as either a distributed amplifier or a distributed mixer. Functional reconfigurability is achieved using one bit programming without changing the signal path. The programmable module in its distributed amplifier mode provides a gain of 8dB in a 3-8 GHz bandwidth. When switched to the distributed mixer mode, it shows a measured average conversion gain of 4dB in a 1-16GHz bandwidth. This circuit is fabricated in a standard 130nm CMOS technology and …

A Linear Programming Approach To Shipboard Electrical System Modeling, Ricky R. Chan, Scott D. Sudhoff, Yonggon Lee, Edwin L. Zivi

Department of Electrical and Computer Engineering Faculty Publications

Operability and dependability metrics can be a valuable tool in early ship design by providing a quantitative analysis of the robustness of the ship's integrated engineering plant (IEP). However, the use of these metrics involves large numbers of time domain simulations of the IEP. The simulation of such a complex system, which includes electrical and thermal subsystems, can be problematic in terms of computational efficiency. In this paper, a simplified modeling approach based on the fundamental power limitations is set forth. The power flow problem is posed as a linear programming problem which is solved using a simplex method.

A Mimo-Ofdm Channel Estimation Scheme Utilizing Complementary Sequences, T. R. Qureshi, M. D. Zoltowski, R. Calderbank

Department of Electrical and Computer Engineering Faculty Publications

We present a pilot-assisted method for estimating the frequency selective channel in a MIMO-OFDM system. The pilot sequence is designed using the DFT of the Golay complementary sequences. Novel exploitation of the perfect autocorrelation property of Golay complementary sequences, in conjunction with OSTBC based pilot waveform scheduling across multiple OFDM frames, facilitates simple separation of the channel mixtures at the receive antennas. The DFT length used to transform the complementary sequence into the frequency domain is shown to be a key critical parameter for correctly estimating the channel. This channel estimation scheme is then extended to antenna arrays of arbitrary …

Computer Graphics Technology Faculty Publications

According to the Association of Technology, Management, and Applied Engineering (ATMAE), graduate-level studies in technology are designed to prepare technologists to focus on the applied challenges of society, industry, and government through integration- and implementation- oriented activities (2009). Although the association’s affiliated institutions and membership have been interested in research and graduate education for many years, increased discussion is needed concerning both the goals and delivery of graduate programs leading to master’s and doctoral degrees related to the field for the 21st century. Many of the academic participants in this organization, as well as others, work at universities that include …

A Subject Librarian’S Guide To Collaborating On E-Science Projects, Jeremy R. Garritano, Jake R. Carlson

Libraries Research Publications

For liaison or subject librarians, entering into the emerging area of providing researchers with data services or partnering with them on cyberinfrastructure projects can be a daunting task. This article will provide some advice as to what to expect and how providing data services can be folded into other liaison duties. New skills for librarians and traditional skills that can be adapted to data curation work will also be discussed. A case study on the authors' experiences collaborating with two chemistry faculty on an e-science project serves as the framework for the majority of this article.

Institutional Repositories And Research Data Curation In A Distributed Environment, Michael Witt

Libraries Research Publications

Broadly speaking, the lack of a framework for organizing, preserving, and making research data available for the long-term has resulted in valuable datasets becoming lost or discarded. The approach of the Distributed Data Curation Center of the Purdue University Libraries has been to integrate librarians and the principles of library and archival sciences with domain sciences, computer and information sciences, and information technology to address the challenges of managing collections of research data and to learn how to better support interdisciplinary research through data curation. One piece of infrastructure that supports these activities is a “distributed institutional repository” that includes …

Invisible Hands: Recognizing Archivists’ Work To Make Records Accessible, Sammie L. Morris, Shirley K. Rose

Libraries Research Publications

Two faculty members, one an archivist and the other a rhetoric and composition scholar/professor collaborated in processing the papers of a rhetoric and composition scholar. This project allowed the archivist to gain a better understanding of archival researchers' needs, while allowing the researcher to better understand the thought process and activities inherent in archival processing-- the activities of organizing, describing, and preserving primary source materials in the archives. Through this article the authors seek to demystify and increase transparency of archival processing, while enhancing researchers' abilities to interpret the archival collections with which they work.

Libraries Faculty and Staff Scholarship and Research

This article describes the genesis of Vanderbilt University's Peabody Academic Library Leadership Institute as an outcome of a particular philosophy. That philosophy is based on the concept that to fulfill their potential contributions, academic libraries need to direct their planning, resources, and services to support the priorities of their parent institutions. This article addresses the need for campus-focused leadership training; higher education leadership training for academic librarians; and the higher education context for libraries. It describes why Vanderbilt's Peabody College of Education and Human Development initiated a professional development institute for librarians. It describes the institute's history, curriculum, and assessment …

Cues To Contrastive Focus In Romanian, Alis Manolescu, Daniel J. Olson, Marta Ortega-Llebaria

School of Languages and Cultures Faculty Publications

In this study we measured patterns of pitch alignment, pitch range and duration in relation to broad and contrastive focus in Romanian. In declarative sentences with broad focus, speakers place a pitch accent on each lexically stressed syllable with peaks that become progressively lower towards the end of the sentence. In prenuclear accents peaks align with the post-tonic syllable. In declarative sentences with contrastive focus, speakers use strategies based on pitch and duration in order to build a maximum contrast between the word under focus and those in pre- and post-focal contexts: an expanded pitch range under focus and a …

Extensive Training Is Insufficient To Produce The Work-Ethic Effect In Pigeons, Marco Vasconcelos, Peter J. Urcuioli

Department of Psychological Sciences Faculty Publications

Zentall and Singer (2007a) hypothesized that our failure to replicate the work-ethic effect in pigeons (Vasconcelos, Urcuioli, & Lionello-DeNolf, 2007) was due to insufficient overtraining following acquisition of the high- and low-effort discriminations. We tested this hypothesis using the original work-ethic procedure (Experiment 1) and one similar to that used with starlings (Experiment 2) by providing at least 60 overtraining sessions. Despite this extensive overtraining, neither experiment revealed a significant preference for stimuli obtained after high effort. Together with other findings, these data support our contention that pigeons do not reliably show a work-ethic effect.

Building The Latin America We Want: Supplementing Representative Democracies With Consensus-Building, Mariana Hernández Crespo

Cardozo Journal of Conflict Resolution

This article is about using consensus-building to create channels for meaningful participation in public decision-making, in order to supplement representative democracies in Latin America. I argue that the addition of a consensus-building mechanism into the legislative process will create the necessary forum for stakeholders to contribute to the framing and resolution of issues of public concern. Furthermore, as Susskind has argued, allowing citizens to participate at the beginning of decision-making processes will make legislative outcomes more legitimate and decrease the level of political dissatisfaction.

State Regulation Of Arbitration Proceedings: Judicial Review Of Arbitration Awards By State Courts, Stephen K. Huber

Cardozo Journal of Conflict Resolution

Judges Gone Wild: Why Breaking The Mediation Confidentiality Privilege For Acting In "Bad Faith" Should Be Reevaluated In Court-Ordered Mandatory Mediation, Samara Zimmerman

Cardozo Journal of Conflict Resolution

This Note focuses on the reasons why a good faith requirement or a bad faith exception for breaking mediation confidentiality is objectionable and offers an alternative for the Florida court system that, if implemented, could mitigate such disadvantages. I will discuss "the intersection between [a] court-ordered mediation, the confidentiality of which is mandated by law ... and the power of a court to control proceedings," and persons who appear before it by sanctioning conduct that taking place in mediation. Part II of this Note will begin by providing a background to the Doe v. Francis civil case. It will highlight …

Transcript: Workshop On The Future Of The Legal Course Book, Edward Rubin, Kellye Testy, Ronald Collins, David M. Skover

Seattle University Law Review

Most every law school right now is thinking about its curriculum. The Carnegie Report certainly was a big factor in spurring that, although curricular reform is something that law schools, of course, are always engaged in. It moves at a glacial pace sometimes. One of the things that really struck us here at Seattle University, as everyone started to talk about Carnegie and started to talk about curricular reform, is that it was, frankly, a bit of old news to us. Seattle University School of Law has always prided itself on being at the forefront of legal education in many …

Effect Of Using Threadfin Shad As Forage For Channel Catfish Fed Daily Or Every Third Day, Bartholomew W. Green, Peter Perschbacher, Gerald Ludwig

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

We evaluated whether stocking threadfin shad Dorosoma petenense as a forage fish in multiple-batch production ponds for channel catfish Ictalurus punctatus could substitute for formulated feed when channel catfish were fed daily or every 3 d. A completely randomized design in a 232 factorial arrangement was used for the experiment, which was conducted in twelve 0.1-ha earthen ponds. Prespawn adult threadfin shad were stocked at 404 kg/ha in six of the ponds, whereas the remaining ponds received no threadfin shad. Channel catfish stockers (0.35 kg/fish) were stocked at 5,040 kg/ha, and fingerlings (28.2 g/fish) were stocked at 14,820 fish/ha. Channel …

Wus And Stm-Based Reporter Genes For Studying Meristem Development In Poplar, Y. Bao, P. Dharmawardhana, R. S. Arias, M. B. Allen, C. Ma, Steven H. Strauss

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

We describe the development of a reporter system for monitoring meristem initiation in poplar using promoters of poplar homologs to the meristem-active regulatory genes WUSCHEL (WUS) and SHOOTMERISTEMLESS (STM). When ~3 kb of the 5' flanking regions of close homologs were used to drive expression of the GUSPlus gene, 50–60% of the transgenic events showed expression in apical and axillary meristems. However, expression was also common in other organs, including in leaf veins (40 and 46% of WUS and STM transgenic events, respectively) and hydathodes (56% of WUS transgenic events). Histochemical GUS staining of explants during callogenesis and shoot …

Vegetation Of Utah, R. Douglas Ramsey, Neil E. West

Wildland Resources Faculty Publications

In order to organize and facilitate management of Utah’s ecosystems, generalization of the ecological variation found across the state is necessary. Ecosystems involve complex interactions between environment and biota, and there have been many efforts to generalize and categorize these interactions in order to gain a better understanding of their structure and organization. The most common method of categorizing ecological variations across large landscapes today incorporates the ecoregion concept. Ecoregions are geographic delineations of landscapes containing ecosystems linked by similar climatic, geologic, soil, and landform characteristics. The primary characteristics used to delineate ecoregions vary depending on the overall goal of …
