A Quantitative Synthesis Of The Medicinal Ethnobotany Of The Malinké Of Mali And The Asháninka Of Peru, With A New Theoretical Framework, Nathaniel Bletter

Publications and Research

Background: Although ethnomedically and taxonomically guided searches for new medicinal plants can improve the percentage of plants found containing active compounds when compared to random sampling, ethnobotany has fulfilled little of its promise in the last few decades to deliver a bounty of new, laboratory-proven medicinal plants and compounds. It is quite difficult to test, isolate, and elucidate the structure and mechanism of compounds from the plethora of new medicinal plant uses described each year with limited laboratory time and resources and the high cost of clinical trials of new drug candidates.

Methods: A new quantitative theoretical framework of mathematical …

Reputation-Based Resilient Data Aggregation In Sensor Network, Carlos R. Perez

Department of Electrical and Computer Engineering Masters Theses

Data aggregation, or the fusing of many sensor measurements into a single summary, has been proposed as an important primitive in wireless sensor networks. But data aggregation is vulnerable to security attacks and natural failures where a few nodes can drastically alter the result of the aggregation by reporting erroneous data. In this thesis we present RDAS, a robust data aggregation protocol that uses a reputation-based approach to identify and isolate malicious nodes in a sensor network. RDAS is based on a hierarchical clustering arrangement of nodes, where a cluster head analyzes data from the cluster nodes to determine the …

Volumetric Visualization Of Nexrad Level Ii Doppler Weather Data From Multiple Sites, Yi Ru

Purdue Polytechnic Masters Theses

Weather visualization is critical for operational forecasters and weather researchers to analyze, monitor, and predict severe weather events such as storms, tornadoes, and hurricanes. Usually measured weather datasets such as NEXRAD Level II radar data contain some errors and have temporal aliasing issues, so that the raw data cannot represent the true meteorological patterns. Existing weather visualization packages usually ignore these problems, thus they fail to unveil some detailed information and cannot meet the needs of professional meteorologists. Most displays generated by those packages are limited to 2D images, 3D point clouds, or iso-surfaces. Those displays are not able to …

A Stochastic Multiple Players Multi-Issues Bargaining Model For The Piave River Basin, Alessandra Sgobbi, Carlo Carraro

Fondazione Eni Enrico Mattei Working Papers

The objective of this paper is to investigate the usefulness of non-cooperative bargaining theory for the analysis of negotiations on water allocation and management. We explore the impacts of different economic incentives, a stochastic environment and varying individual preferences on players’ strategies and equilibrium outcomes through numerical simulations of a multilateral, multiple issues, non-cooperative bargaining model of water allocation in the Piave River Basin, in the North East of Italy. Players negotiate in an alternating-offer manner over the sharing of water resources (quantity and quality). Exogenous uncertainty over the size of the negotiated amount of water is introduced to capture …

Technology Spillovers And Stability Of International Climate Coalitions, Miyuki Nagashima, Rob Dellink

Fondazione Eni Enrico Mattei Working Papers

Cooperation in international environmental agreements appears difficult to attain because of strong free-riding incentives. This paper explores how different technology spillover mechanisms among regions can influence the incentive structures to join and stabilise an international agreement. We use an applied modelling framework (STACO) that enables us to investigate stability of partial climate coalitions. Technology spillovers to coalition members increase their incentives to stay in the coalition and reduce abatement costs, which leads to larger global payoffs and a lower global CO2 stock. Several theories on the impact of technology spillovers are evaluated by simulating a range of alternative specifications. We …

The Computational Difficulty Of Bribery In Qualitative Coalitional Games, Andrew J. Dowell, Michael Wooldridge, Peter Mcburney

Fondazione Eni Enrico Mattei Working Papers

Qualitative coalitional games (QCG) are representations of coalitional games in which self interested agents, each with their own individual goals, group together in order to achieve a set of goals which satisfy all the agents within that group. In such a representation, it is the strategy of the agents to find the best coalition to join. Previous work into QCGs has investigated the computational complexity of determining which is the best coalition to join. We plan to expand on this work by investigating the computational complexity of computing agent power in QCGs as well as by showing that insincere strategies, …

Comparative Nutrient Data For Two Locations On The Marstons Mills River

Watershed Access Lab Projects

On October 30, 2007, we deployed water samplers at two locations along the Marstons Mills River: River Road and Hyrdo Dam/Route 28. We programmed a Sigma at each location to take a water sample each hour for 24 hours, to determine the amount of dissolved nutrients in the water in the course of one day. When compared to the discharge at each site, we found that the Hydro Dam location moved nearly 117 000 000 liters of water, 10 000 grams of phosphorus, and 25 000 grams of nitrogen-nitrate each day. Only a short distance upstream, the River Road location …

How Healthy Is Furnace Brook

Watershed Access Lab Projects

Located across the street from the High school is Furnace Brook. Mike Gilbert and I are conducting an independent Study to determine the relative health of the Furnace Brook. This small stream is a tributary of the South River in Marshfield, Ma. To access the health will we be using a macro-invertebrate biological index as our primary tool? We will also be conducting a riparian survey as well as both a stream profile and flow. To start with we scouted the watershed using both aerial photos and Google earth. After driving to several potential areas we designated three sample sites: …

Rumford River Monitoring Project

Watershed Access Lab Projects

Land use within a watershed can negatively impact water quality. Students investigated these impacts by collecting water samples at one sample site along the Rumford River at Route 123, Norton, MA. These samples were analyzed for phosphorus and nitrogen levels, as well as temperature and dissolved oxygen. Results of these tests are as follows:

The greatest potential impacts come from run off. Most of the land around the Rumford River has been developed for residential housing. These houses have septic systems for waste disposal. The TCP golf course is also located near the Norton Reservoir. Potential sources of nitrogen come …

Palmer River Water Discharge And Nutrient Study

Watershed Access Lab Projects

Can significant differences in Discharge and Nutrient concentration & load be determined or inferred for the Palmer River? Students studied 2 sites. These were located at Wilmarth Bridge Road (just off of Route 44) and at Reed Street (further south & downstream). Between the 2 sites are a few farms as well as a golf course. It is possible that runoff from these 2 sources has influenced the amount of phosphates &/or nitrates found in the Palmer River. Most Primary & Secondary habitat characteristics were the same for both sites; though Reed Street exhibited more variations

Students collected data on …

Web Based Resource Management For Multi-Tiered Web Applications, Bryce Daniel Ott

Theses and Dissertations

The currently emerging trend of building more complex web applications to solve increasingly more involved software problems has led to the the need for a more automated and practical means for deploying resources required by these advanced web applications. As web based applications become more complex and involve more developers, greater system redundancy, and a larger number of components, traditional means of resource deployment become painfully inadequate as they fail to scale sufficiently. The purpose of this research is to provide evidence that a more sound and scalable test and deployment process can be employed and that many of the …

Evolution Of A Database Security Course: Using Non-Enterprise Teaching Tools, Justin Brown

Australian Information Security Management Conference

This paper examines the issues in delivering a university unit of teaching in database security, examining problems in database environment selection and the ability to provide hands on training for students via oncampus and online modes. Initial problems with Linux and then Windows based enterprise database environments prompted the adoption of Microsoft Access as a database tool that was easier to deliver in-class and online. Though Access is file based and has fundamental flaws in its security implementation (within the enterprise context) it can be tweaked to emulate RDBMS level security, allowing students to see how a properly designed security …

Network Security – Is Ip Telephony Helping The Cause?, Paul Hansen, Andrew Woodward

Australian Information Security Management Conference

The major players in the Public Branch Exchange (PBX) market are moving rapidly towards the implementation of IP Telephony. What will be the effect on network security overall? Will the push to IP Telephony damage the good work already devoted to security networks? As more doorways open up on our networks there is an increased chance we have opened another unseen vector for hackers and other malicious organisation or individuals to access the data stored on server and users workstations, corrupting that data or destroying it. Is it better from a security perspective to have IP telephony only between PBX …

Network Security Devices And Protocols Using State Model Diagrams, C. Nuangjamnong, D. Veal, S. P. Maj

Australian Information Security Management Conference

Network security is concerned with protecting sensitive information, limiting unauthorised access, and reinforcing network performance. An important factor in network security is encryption. Internet Security Protocol (IPSec) is the de facto open standard for encryption and replaces the older Cisco Encryption Technology (CET). Both encryption protocols are typically implemented and managed using the text based Command Line Interface (CLI). A graphical user interface (GUI) is available; however, it is not routinely used. Regardless of whether the CLI or GUI is used, both encryption suites are complex to implement and manage. State Model Diagrams (SMDs) were developed and successfully used as …

Device- Versus Network-Centric Authentication Paradigms For Mobile Devices: Operational And Perceptual Trade-Offs, S. Karatzouni, N. L. Clarke, S. M. Furnell

Australian Information Security Management Conference

The increasing capability and functionality of mobile devices is leading to a corresponding increase in the need for security to prevent unauthorised access. Indeed, as the data and services accessed via mobile devices become more sensitive, the existing method of user authentication (predominately based upon Personal Identification Numbers) appears increasingly insufficient. An alternative basis for authentication is offered by biometric approaches; which have the potential to be implemented in a non-intrusive manner and also enable authentication to be applied in an ongoing manner, beyond initial point-of-entry. However, the implementation of any authentication mechanism, particularly biometric approaches, introduces considerations of where …

Importance Of Verification And Validation Of Data Sources In Attaining Information Superiority, Gautham Kasinath, Leisa Armstrong

Australian Information Security Management Conference

Information superiority has been defined as a state that is achieved when a competitive advantage is derived from the ability to exploit a superior information position. To achieve such a superior information position enterprises and nations, alike, must not only collect and record correct, accurate, timely and useful information but also ensure that information recorded is not lost to competitors due to lack of comprehensive security and leaks. Further, enterprises that aim to attain information superiority must also ensure mechanisms of validating and verifying information to reduce the chances of mis-information. Although, research has been carried out into ways to …

Analysis Of Pki As A Means Of Securing Odf Documents, Gautham Kasinath, Leisa Armstrong

Australian Information Security Management Conference

Public Key Infrastructure (PKI) has for the last two decades been a means of securing systems and communication. With the adoption of Open Document Format (ODF) as an ISO standard, the question remains if the unpopular, expensive, complex and unmaintainable PKI can prove to be a viable means of securing ODF documents. This paper analyses the drawbacks of PKI and evaluates the usefulness of PKI in provisioning robust, cheap and maintainable XML security to XML based ODF. This paper also evaluates the existing research on XML security, more specifically fine grained access control.
