Information Technology Implementation Decisions To Support The Kentucky Mesonet, D. Michael Grogan

Masters Theses & Specialist Projects

The Kentucky Mesonet is a high-density, mesoscale network of automated meteorological and climatological sensing platforms being developed across the commonwealth. Data communications, collection, processing, and delivery mechanisms play a critical role in such networks, and the World Meteorological Organization recognizes that “an observing system is not complete unless it is connected to other systems that deliver the data to the users.” This document reviews the implementation steps, decisions, and rationale surrounding communications and computing infrastructure development to support the Mesonet. A general overview of the network and technology-related research is provided followed by a review of pertinent literature related to ...


Barcoding Of Arrow Worms (Phylum Chaetognatha) From Three Oceans: Genetic Diversity And Evolution Within An Enigmatic Phylum, Robert M. Jennings, Ann Bucklin, Annelies Pierrot-Bults 2010 University of Massachusetts Boston

Barcoding Of Arrow Worms (Phylum Chaetognatha) From Three Oceans: Genetic Diversity And Evolution Within An Enigmatic Phylum, Robert M. Jennings, Ann Bucklin, Annelies Pierrot-Bults

Biology Faculty Publication Series

Arrow worms (Phylum Chaetognatha) are abundant planktonic organisms and important predators in many food webs; yet, the classification and evolutionary relationships among chaetognath species remain poorly understood. A seemingly simple body plan is underlain by subtle variation in morphological details, obscuring the affinities of species within the phylum. Many species achieve near global distributions, spanning the same latitudinal bands in all ocean basins, while others present disjunct ranges, in some cases with the same species apparently found at both poles. To better understand how these complex evolutionary and geographic variables are reflected in the species makeup of chaetognaths, we analyze ...


Detection Of Outliers In Time Series Data, Samson Sifael Kiware 2010 Marquette University

Detection Of Outliers In Time Series Data, Samson Sifael Kiware

Master's Theses (2009 -)

This thesis presents the detection of time series outliers. The data set used in this work is provided by the GasDay Project at Marquette University, which produces mathematical models to predict the consumption of natural gas for Local Distribution Companies (LDCs). Flow with no outliers is required to develop and train accurate models. GasDay is using statistical approaches motivated by normally distributed samples such as the 3 -sigma rule and the 5 -sigma rule to aid the experts in detecting outliers in residuals from the models. However, the Jarque-Bera statistical test shows that the residuals from the GasDay models are ...


Detecting Malicious Javascript, Matthew F. Der 2010 University of Richmond

Detecting Malicious Javascript, Matthew F. Der

Honors Theses

The increased use of the World Wide Web and JavaScript as a scripting language for Web pages have made JavaScript a popular attack vector for infecting users' machines with malware. Additionally, attackers often obfuscate their code to avoid detection, which heightens the challenge and complexity of automated defense systems. We present two analyses of malicious scripts and suggest how they could be extended into intrusion detection systems. For our analyses we use a sample of deobfuscated malicious and benign scripts collected from actual Web sites. First, using our malicious sample, we perform a manual analysis of attack signatures, identifying four ...


Analysis Of Boolean Functions With High Second Order Nonlinearity, Corneliu A. Bodea 2010 University of Richmond

Analysis Of Boolean Functions With High Second Order Nonlinearity, Corneliu A. Bodea

Honors Theses

Highly nonlinear Boolean functions play a central role in the design and security analysis of high speed stream cyphers and block cyphers. We focus on analyzing the structure of Boolean functions that exhibit high second order nonlinearity. We commence with a theoretical overview of Boolean functions and Reed- Muller codes. We then introduce a new equivalence relation, 2-equivalence, for which we prove a number of important properties. Finally, we analyze the second order nonlinearity of concatenations of two Boolean functions.


Contributors’ Preference In Open Source Software Usability: An Empirical Study, Arif Raza, Luiz Fernando Capretz 2010 The University of Western Ontario

Contributors’ Preference In Open Source Software Usability: An Empirical Study, Arif Raza, Luiz Fernando Capretz

Electrical and Computer Engineering Publications

The fact that the number of users of open source software (OSS) is practically un-limited and that ultimately the software quality is determined by end user’s experience, makes the usability an even more critical quality attribute than it is for proprietary software. With the sharp increase in use of open source projects by both individuals and organizations, the level of usability and related issues must be addressed more seriously. The research model of this empirical investigation studies and establishes the relationship between the key usability factors from contributors’ perspective and OSS usability. A data set of 78 OSS contributors ...

Carbon Dynamics In The Tropics, Ann E. Russell, James W. Raich, Ricardo Bedoya Arrieta, Oscar Valverde-Barrantes, Eugenio González

Natural Resource Ecology and Management Publications

Native tree species differed in their effects on above- and belowground carbon stocks and fluxes in these 16-yr-old experimental plantations at La Selva Biological Station, Costa Rica. Results were explained primarily by differences in growth rates, C allocation, turnover rates, and tissue chemistry. In this experiment established in an abandoned pasture, all five tree species had attained biomass amounts similar to that of nearby mature forest, whereas the abandoned pasture control remained in arrested succession. Carbon sequestration averaged 5.2 Mg∙ha-1∙yr-1 across species, close to the annual per capita fossil-fuel use in the United States of 5.3 ...

Livestock Protection Dogs In The 21st Century: Is An Ancient Tool Relevant To Modern Conservation Challenges?, Thomas M. Gehring, Kurt C. VerCauteren, Jean-Marc Landry 2010 USDA-APHIS-Wildlife Services

Livestock Protection Dogs In The 21st Century: Is An Ancient Tool Relevant To Modern Conservation Challenges?, Thomas M. Gehring, Kurt C. Vercauteren, Jean-Marc Landry

USDA National Wildlife Research Center - Staff Publications

Europe and North America share a similar history in the extirpation and subsequent recovery of large carnivore and ungulate species. Both continents face challenges and opportunities for managing human-wildlife conflict at the junction of livestock production and wildlife conservation. Predation of livestock and disease transmission between wildlife and livestock is an ongoing and escalating worldwide issue. In order to manage this conflict, producers need effective tools, and they have used livestock protection dogs (LPDs) for reducing predation for well over 2000 years. We review the history of the use of LPDs, including the loss of information on their use and ...

Input-Output Analysis Of Irish Construction Sector Greenhouse Gas Emissions, Adolf Acquaye, Aidan Duffy 2010 Dublin Institute of Technology

Input-Output Analysis Of Irish Construction Sector Greenhouse Gas Emissions, Adolf Acquaye, Aidan Duffy

Articles

Ireland is committed to limiting its greenhouse gas (GHG) emissions to 113% of 1990 levels over the period 2008-12 and to 84% of 2005 levels by 2020 under the Kyoto Agreement and the EU’s ’20 20’ by 2020 respectively. National policies have targeted many industry sectors but have failed to directly tackle GHG emissions associated with construction activity. This paper estimates energy and GHG emissions intensities of the Irish construction sector and subsectors and estimates its contribution to Irish national emissions. This information is used to identify and assess the impacts of policy measures which would result in a ...

Managing Media Rich Geo-Spatial Annotations For A Map-Based Mobile Application Using Clustering, Khasfariyati Razikin, Dion Hoe-Lian Goh, Ee Peng Lim, Aixin Sun, Yin-Leng Theng, Thi Nhu Quynh Kim, Kalyani Chatterjea, Chew-Hung Chang

Research Collection School Of Information Systems

With the prevalence of mobile devices that are equipped with wireless Internet capabilities and Global Positioning System (GPS) functionality, the creation and access of user-generated content are extended to users on the go. Such content are tied to real world objects, in the form of geospatial annotations, and it is only natural that these annotations are visualized using a map-based approach. However, viewing maps that are filled with annotations could hinder the serendipitous discovery of data, especially on the small screens of mobile devices. This calls for a need to manage the annotations. In this paper, we introduce a mobile ...


Policy-Driven Distributed And Collaborative Demand Response In Multi-Domain Commercial Buildings, Archan MISRA, Henning SCHULZRINNE 2010 Singapore Management University

Policy-Driven Distributed And Collaborative Demand Response In Multi-Domain Commercial Buildings, Archan Misra, Henning Schulzrinne

Research Collection School Of Information Systems

Enabling a sophisticated Demand Response (DR) framework, whereby individual consumers adapt their electricity consumption in response to price variations, is a major objective of the emerging Smart Grid. We first point out why the current model, of EMS-based centralized control of a static repository of high load appliances, is inappropriate for supporting DR in future commercial buildings and campuses, where the consuming appliances are controlled by multiple users. To enable DR in such multi-domain environments, we envision a more collaborative and autonomous model, where a large set of heterogeneous smart electrical devices autonomously self-organize and negotiate their collective DR. Enabling ...


Algorithms For Constrained K-Nearest Neighbor Queries Over Moving Object Trajectories, Yunjun GAO, Baihua ZHENG, Gencai CHEN, Qing LI, Chun CHEN 2010 Singapore Management University

Algorithms For Constrained K-Nearest Neighbor Queries Over Moving Object Trajectories, Yunjun Gao, Baihua Zheng, Gencai Chen, Qing Li, Chun Chen

Research Collection School Of Information Systems

An important query for spatio-temporal databases is to find nearest trajectories of moving objects. Existing work on this topic focuses on the closest trajectories in the whole data space. In this paper, we introduce and solve constrained k-nearest neighbor (CkNN) queries and historical continuous CkNN (HCCkNN) queries on R-tree-like structures storing historical information about moving object trajectories. Given a trajectory set D, a query object (point or trajectory) q, a temporal extent T, and a constrained region CR, (i) a CkNN query over trajectories retrieves from D within T, the k (≥ 1) trajectories that lie closest to q and intersect ...


Generating Synonyms Based On Query Log Data, Stelios PAPARIZOS, Tao CHENG, Hady W. LAUW 2010 Singapore Management University

Generating Synonyms Based On Query Log Data, Stelios Paparizos, Tao Cheng, Hady W. Lauw

Research Collection School Of Information Systems

An approach is described for generating synonyms to supplement at least one information item, such as, in one case, a set of related items. The approach can involve an expansion phase, a clean-up phase, and a reduction phase. In the expansion phase, the approach identifies, for each related item, a set of initial synonym candidates. In the clean-up phase, the approach removes noise from the set of initial synonym candidates (if such noise exists), to provide a set of filtered synonym candidate items. In the reduction phase, the approach ranks and applies a threshold (or thresholds) to the set of ...

Pretty Lights, Nicholas (Nick) delMas, Matthew (Matt) Maniaci 2010 California Polytechnic State University - San Luis Obispo

Pretty Lights, Nicholas (Nick) Delmas, Matthew (Matt) Maniaci

Computer Engineering

Digital media players often include a visualization component that allows a user to watch a visualization synchronized to their music or videos. This project uses the visualization plugin API of an existing media playback program (WinAmp) but it displays its visuals using physical LED lights. Instead of outputting visuals to the computer screen, data is sent over USB to a micro controller that runs the LED lights. This project aims to give users a more visceral visual experience than traditional visualizations on the computer screen.
