Power Quality Survey Factor Analysis Using Multivariable Linear Regression (Mvlr), Chandana Herath, Victor J. Gosbell, Sarath Perera, David A. Stirling

Dr David Stirling

During the past two decades, there has been a considerable number of Power Quality (PQ) monitoring programs completed throughout the world. The information collected during these surveys can provide a detailed picture of the expected electrical environment help utilities to plan their future networks in relation to power quality performance. The mass of data gathered for a sample of sites of a large-scale power quality (PQ) survey of this nature has the potential to reveal good and bad influences on power quality if an appropriate procedure for analysis can be determined. If it is known which characteristics are more important …

The regression model identified "respect", "smile" and "skill" …

A Survey And Tutorial Of Rfid Anti-Collision Protocols, Dheeraj Klair, Kwan-Wu Chin, Raad Raad

Dr Raad Raad

RFID technologies have revolutionized the asset tracking industry, with applications ranging from automated checkout to monitoring the medication intakes of elderlies. In all these applications, fast, and in some cases energy efficient, tag reading is desirable, especially with increasing tag numbers. In practice, tag reading protocols face many problems. A key one being tag collision, which occurs when multiple tags reply simultaneously to a reader. As a result, an RFID reader experiences low tag reading performance, and wastes valuable energy. Therefore, it is important that RFID application developers are aware of current tag reading protocols. To this end, this paper …

Interactive Effects Of Networked Publics And Social Media On Transforming The Public Sphere: A Survey Of Iran's Leaderless 'Social Media Revolution', Akemi Chatfield, Hans Scholl, Reza Akbari, Nima Mirzayi

Dr Akemi Chatfield

It has been argued that hierarchical 'command and control' leadership is required to coordinate massive and rapid military or disaster response. Against this, the concept of leaderless 'social media revolution' refers to the wide-spread use of Web 2.0 social media by ordinary citizens to transform the public sphere and engage in collective political action, including coordinating massive and rapid protests against government. However, conceptual and empirical research efforts remain scarce to date. This research draws on the emergent perspective on causal agency in effecting change in social systems to examine our research proposition that the interactive effects of networked publics …

Setting Directions For Research Capacity Building In Primary Health Care: A Survey Of A Research Network, Karin Ried, Elizabeth Farmer, Kathryn M. Weston

A Survey Of Some Mathematical Results For Highly Frictional Granular Materials, Grant Cox, Ngamta Thamwattana, James Hill

Dr Ngamta Thamwattana

Recently the authors have exploited the notion of a highly frictional granular material to derive analytical solutions for certain problems. Generally, we use the term highly frictional granular material to refer to those materials which possess an angle of internal friction such that the trigonometric sine of the angle of internal friction is close to unity. There are many granular materials for which this is the case, such as black and brown coal and limestone powder. For such materials formal perturbation solutions can be derived for which the zeroth-order solution corresponds to an angle of internal friction precisely equal to …

Madison 1, Bush 0: Survey Testing Mr. Madison's Hypotheses, Daniel Gordon

Touro Law Review

For over fifty years, James Madison warned the American colonies and the new United States of America of the dangers of linking religion with government. Madison fought in his home state of Virginia to separate church and state and continued the fight as a congressman and as president. Between 2001 and 2009, President George W. Bush overtly linked religion with government. President Bush's efforts provide the opportunity to test President Madison's hypothesis that danger arises in American society when religion and government are linked. The Gallup Organization in its public opinion testing provides the means used in this Article to …

Increasing Response Rates To Web-Based Surveys, Martha C. Monroe, Damian C. Adams

The Journal of Extension

We review a popular method for collecing data—Web-based surveys. Although Web surveys are popular, one major concern is their typically low response rates. Using the Dillman et al. (2009) approach, we designed, pre-tested, and implemented a survey on climate change with Extension professionals in the Southeast. The Dillman approach worked well, and we generated response rates as high as 79%. However, the method was not problem-free. We share several lessons learned and recommendations for increasing response rates with Web-based surveys and draw attention to the importance of personalized and repeated contact for improving survey response rates.

Finding Upstate South Carolina's Consumers' Willingness To Pay For Local Food With A Price Premium Donation To Local Food Banks, Emily Young

All Theses

The objective of this study is to evaluate Upstate South Carolina consumers' willingness to pay for a system in which local food banks and local farms support one another. The proposed system will be based on local food consumers paying a price premium for locally grown agricultural products, and this premium is then donated to local food banks. The food banks would act as intermediaries to improve sustainability of local farms and in the long term, this system is expected to provide external benefits to local economic development. The study uses a consumer demand mail survey to record opinions about, …

Coordination In Wireless Sensor-Actuator Networks: A Survey, Hamidreza Salarian, Kwan-Wu Chin, Fazel Naghdy

Associate Professor Kwan-Wu Chin

"Wireless Sensor-Actuator Networks (WSANs) have a myriad of applications, ranging from pacifying bulls to controlling light intensity in homes automatically. An important aspect of WSANs is coordination. Unlike conventional Wireless Sensor Networks (WSNs), sensor and actuator nodes must work hand-in-hand to collect and forward data, and act on any sensed data collaboratively, promptly and reliably. To this end, this paper reviews current state-of-the-art techniques that address this fundamental problem: More specifically, we review techniques in the following areas: (i) sensor-actuator coordination, (ii) routing protocols, (iii) transport protocols, and (iv) actuator-to-actuator coordination protocols. We provide an extensive qualitative comparison of their …
