Tinypack Xml: Real Time Xml Compression For Wireless Sensor Networks, Tommy Szalapski, Sanjay Madria, Mark Linderman Aug 2012

Tinypack Xml: Real Time Xml Compression For Wireless Sensor Networks, Tommy Szalapski, Sanjay Madria, Mark Linderman

Computer Science Faculty Research & Creative Works

Wireless networks possess significant limitations in bandwidth. Additionally, real-time networks cannot tolerate high latency. While some good XML compression algorithms exist, there remains a need for methods that reduce latency and bandwidth usage further in real time wireless applications. This paper presents a new compression scheme which reduces bandwidth while minimizing latency of XML data while in transit. XML structural data is reduced to format strings and arguments are sent as they are generated using modifications of real-time compression techniques specific to each data type. Methods are introduced to gracefully handle lost data in environments where delivery of all packets …

The Minnesota Maple Series: Community-Generated Knowledge Delivered Through An Extension Website, David S. Wilsey, Julie A. Miedtke, Eli Sagor

Journal of Extension

Extension continuously seeks novel and effective approaches to outreach and education. The recent retirement of a longtime content specialist catalyzed members of University of Minnesota Extension's Forestry team to reflect on our instructional capacity (internal and external) and educational design in the realm of maple syrup production. We responded by developing an educational maple blog series that incorporated faculty and community expertise through a participatory, peer-to-peer approach. The blog series expanded and strengthened the state's maple knowledge network, met contributors' and users' content needs and expectations, influenced maple practices, and retained program flexibility for adaptation.

Barriers And Effective Educational Strategies To Develop Extension Agents' Professional Competencies, Dona Lakai, Ksu Jayaratne, Gary E. Moore, Mark J. Kistler Aug 2012

Barriers And Effective Educational Strategies To Develop Extension Agents' Professional Competencies, Dona Lakai, Ksu Jayaratne, Gary E. Moore, Mark J. Kistler

Journal of Extension

The study reported here determined the barriers and effective educational strategies to develop Extension agents' professional competencies. This was a descriptive survey research conducted with a random sample of Extension agents. Increased workload and lack of time and funding were identified as the most constraining barriers of Extension agents acquiring competencies. Extension agents identified the face-to-face small group training workshop as the most effective educational delivery method for acquiring desired Extension competencies. This implies the need for using small group face-to-face training programs close to the work place as a viable alternative for achieving desired results.

From Translation To Cultural Responsiveness: A Garden Program's Evolution In Understanding Educators' Perceptions Of Spanish-Language Resources, Amy Aubrecht, Marcia Eames-Sheavly Aug 2012

From Translation To Cultural Responsiveness: A Garden Program's Evolution In Understanding Educators' Perceptions Of Spanish-Language Resources, Amy Aubrecht, Marcia Eames-Sheavly

Journal of Extension

Addressing needs of the increasing Latino population in the United States necessitates adequate support and resources for Extension educators. Even if a program has identified the need for resources and programming, how does it determine the specifics of that need and better understand the perceptions of educators engaged in programming? What is the starting point? Cornell Garden-Based Learning delved into an initial exploration of these questions using a dual approach: assessing perceived needs of educators using an online survey and personal interviews. Here we offer our findings, a snapshot of the varied and complex perceptions held by NYS educators.

Development Of A Team-Based On-Farm Learning Program While Challenging Soybean Growers To Increase Yield, Vince M. Davis, Linda S. Kull, James A. Nelson Aug 2012

Development Of A Team-Based On-Farm Learning Program While Challenging Soybean Growers To Increase Yield, Vince M. Davis, Linda S. Kull, James A. Nelson

Journal of Extension

Illinois soybean growers have not been satisfied with recent lagging yield trends. A yield "challenge" was created to blend the motivation and creativity of a yield contest with the learning power of teamwork and on-farm demonstration. In the initial year (2010), 123 on-farm side-by-side demonstration plots were located throughout the state; 81% of those locations showed increased soybean yields through additional management, and 55% of the experimental challenge plots were profitable. Participant surveys indicated that 92% learned a new production practice and that 69% would adopt experimental practices on more production acres the following year.

Optimal Estimation Under Nonstandard Conditions, Werner Ploberger, Peter C. B. Phillips Aug 2012

Optimal Estimation Under Nonstandard Conditions, Werner Ploberger, Peter C. B. Phillips

Research Collection School Of Economics

We analyze optimality properties of maximum likelihood (ML) and other estimators when the problem does not necessarily fall within the locally asymptotically normal (LAN) class, therefore covering cases that are excluded from conventional LAN theory such as unit root nonstationary time series. The classical Hajek-Le Cam optimality theory is adapted to cover this situation. We show that the expectation of certain monotone "bowl-shaped" functions of the squared estimation error are minimized by the ML estimator in locally asymptotically quadratic situations, which often occur in nonstationary time series analysis when the LAN property fails. Moreover, we demonstrate a direct connection between …

Mean And Autocovariance Function Estimation Near The Boundary Of Stationarity, Liudas Giraitis, Peter C. B. Phillips Aug 2012

Mean And Autocovariance Function Estimation Near The Boundary Of Stationarity, Liudas Giraitis, Peter C. B. Phillips

Research Collection School Of Economics

We analyze the applicability of standard normal asymptotic theory for linear process models near the boundary of stationarity. Limit results are given for estimation of the mean, autocovariance and autocorrelation functions within the broad region of stationarity that includes near boundary cases which vary with the sample size. The rate of consistency and the validity of the normal asymptotic approximation for the corresponding estimators is determined both by the sample size n and a parameter measuring the proximity of the model to the unit root boundary.

Improving Ethics Education In Accounting: Lessons From Medicine And Law, Chunhui Liu, Lee J. Yao, Nan Hu Aug 2012

Improving Ethics Education In Accounting: Lessons From Medicine And Law, Chunhui Liu, Lee J. Yao, Nan Hu

Research Collection School Of Computing and Information Systems

The purpose of this paper is to offer accounting educators additional perspectives for ethics education by considering teaching approaches from medicine and law. It takes the form of literature review and argument. The paper finds that ethics education in accounting shows deficiencies in terms of code-bound content, less systematic formal training, less informal hands-on training, and less usage of partnering in comparison to ethics education in medicine and law, thereby producing students with higher moral cognitive capabilities. Based on these findings, the authors provide some recommendations for improvement.

Online Feature Selection For Mining Big Data, Steven C. H. Hoi, Jialei Wang, Peilin Zhao, Rong Jin Aug 2012

Online Feature Selection For Mining Big Data, Steven C. H. Hoi, Jialei Wang, Peilin Zhao, Rong Jin

Research Collection School Of Computing and Information Systems

Most studies of online learning require accessing all the attributes/features of training instances. Such a classical setting is not always appropriate for real-world applications when data instances are of high dimensionality or the access to it is expensive to acquire the full set of attributes/features. To address this limitation, we investigate the problem of Online Feature Selection (OFS) in which the online learner is only allowed to maintain a classifier involved a small and fixed number of features. The key challenge of Online Feature Selection is how to make accurate prediction using a small and fixed number of active features. …

Landowners' Knowledge, Attitudes, And Aspirations Towards Woody Biomass Markets In North Carolina, Jasmine Shaw, Dennis Hazel, Robert Bardon, Jay S. Jayaratne Aug 2012

Landowners' Knowledge, Attitudes, And Aspirations Towards Woody Biomass Markets In North Carolina, Jasmine Shaw, Dennis Hazel, Robert Bardon, Jay S. Jayaratne

Journal of Extension

Non-industrial private forest (NIPF) landowners are often not included in discussions of emerging woody biomass markets for energy, yet they will likely be principal suppliers of the resource. Surveys administered to 475 forest landowners before and after an Extension Forestry education program in 10 counties across North Carolina indicated that landowners have low knowledge levels of woody biomass. However, as a result of participating in the training, landowners increased knowledge, had more positive attitudes, and developed aspirations to harvest woody biomass on their land. Extension professionals can use our training model to develop similar woody biomass educational programs.

Refugees Of The Arab Spring: The Syrian Refugees In Lebanon April 2011-April 2012, Sam Van Vliet, Guita Hourani

Faculty Journal Articles

This review of one year influx of Syrian refugees into Lebanon is meant to reveal the political, communitarian and humanitarian factors that shape the State of Lebanon's policy towards it. The Lebanese government has lately adopted a ‘disassociation’ policy regarding the Syrian conflict with the objective of preventing the spill-over of the conflict and the destabilization of the country. Regional and international powers well understand the reasons for this policy, given Lebanon's geopolitical situation, its history and its 'special ties' with Syria. However, while Lebanon might be able to disassociate itself from the political entanglement of the Syrian crisis, it …

A Mean Curvature Model For Capillary Flows In Asymmetric Containers And Conduits, Yongkang Chen, Noël Tavan, Mark M. Weislogel Aug 2012

A Mean Curvature Model For Capillary Flows In Asymmetric Containers And Conduits, Yongkang Chen, Noël Tavan, Mark M. Weislogel

Mechanical and Materials Engineering Faculty Publications and Presentations

Capillarity-driven flows resulting from critical geometric wetting criterion are observed to yield significant shifts of the bulk fluid from one side of the container to the other during "zero gravity" experiments. For wetting fluids, such bulk shift flows consist of advancing and receding menisci sometimes separated by secondary capillary flows such as rivulet-like flows along gaps. Here we study the mean curvature of an advancing meniscus in hopes of approximating a critical boundary condition for fluid dynamics solutions. It is found that the bulk shift flows behave as if the bulk menisci are either “connected” or "disconnected." For the connected …
