JFSP Research Project Reports
The response of plants and animals in the pine forests of southern Florida to variation in fire and hydrological regimes remains inadequately described, hindering the ability of resource managers to manipulate fire and water to achieve desired ecological outcomes. In this study, we took advantage of natural variation in two measures of fire history (the number of days since last fire and the number of times an area had been burned during the previous ten years) and one measure of hydrology (water table elevation) to explore how plants, breeding birds, and wintering birds in slash-pine (Pinus elliottii var. densa) forests …

We evaluated effects of an experimental fuels reduction program on elk, mule deer, and their habitat at the Starkey Experimental Forest and Range (Starkey) in northeastern Oregon. From 2001 to 2003, 26 stands of true fir and Douglas-fir that suffered high rates of mortality from an outbreak of spruce budworm were selectively thinned (spring or summer) and burned (fall) while 27 similar stands were left untreated to serve as experimental controls. We used location data for elk and mule deer collected during spring (1 April–14 June) and summer (15 June–31 August) of 1999–2006 to compare use of treated and untreated …

A Distributed Parabolic Control With Mixed Boundary Conditions, Jose-Luis Menaldi, Domingo Alberto Tarzia
A Distributed Parabolic Control With Mixed Boundary Conditions, Jose-Luis Menaldi, Domingo Alberto Tarzia
Mathematics Faculty Research Publications
We study the asymptotic behavior of an optimal distributed control problem where the state is given by the heat equation with mixed boundary conditions. The parameter α intervenes in the Robin boundary condition and it represents the heat transfer coefficient on a portion Γ1 of the boundary of a given regular n-dimensional domain. For each α, the distributed parabolic control problem optimizes the internal energy g. It is proven that the optimal control ĝα with optimal state uĝαα and optimal adjoint state pĝαα are convergent as α → 1 …

Abstract
Background
Offering specialized programming at substance abuse treatment facilities can help diversify clientele and funding sources, potentially enhancing the facilities' ability to survive and/or expand. Past research has shown that facilities only offering specialized programming for driving under the influence/driving while intoxicated offenders (DUI) are predominately private-for-profit owned. As criminal justice populations, both DUI and other criminal justice offenders, comprise a large proportion of those in community-based substance abuse treatment knowing facilities' characteristics would be important for administrators and policymakers to consider when updating programming, training staff or expanding capacity to ensure efficient use of scarce resources. However, while …

Modeling Immune Response To Bacterial Infection, Carla Roth
The Journal of Undergraduate Research
Mathematical models have begun to play an important role in the study of biology. We will examine this role further by analyzing a specific model of the innate immune system's response to a bacterial infection. Beginning with the biological background of the model, we will move into an explanation of a specific model of this situation followed by a critique of the model and future work to be done with the topic.

Discrete Approximations, Relaxation, And Optimization Of One-Sided Lipschitzian Differential Inclusions In Hilbert Spaces, Tzanko Donchev, Elza Farkhi, Boris S. Mordukhovich
Mathematics Research Reports
We study discrete approximations of nonconvex differential inclusions in Hilbert spaces and dynamic optimization/optimal control problems involving such differential inclusions and their discrete approximations. The underlying feature of the problems under consideration is a modi- fied one-sided Lipschitz condition imposed on the right-hand side (i.e., on the velocity sets) of the differential inclusion, which is a significant improvement of the conventional Lipschitz continuity. Our main attention is paid to establishing efficient conditions that ensure the strong approximation (in the W^1,p-norm as p greater than or equal to 1) of feasible trajectories for the one-sided Lipschitzian differential inclusions under. consideration by …

Geological processes produce structures at multiple scales. A discontinuity in the subsurface can occur due to layering, tectonic activities such as faulting, folding and fractures. Traditional approaches to invert geophysical data employ smoothness constraints. Such methods produce smooth models and thefore sharp contrasts in the medium such as lithological boundaries are not easily discernible. The methods that are able to produce non-smooth models, can help interpret the geological discontinuity. In this paper we examine various approaches to obtain non-smooth models from a finite set of noisy data. Broadly they can be categorized into approaches: (1) imposing non-smooth regularization in the …

RFID technology is gaining adoption on an increasing scale for tracking and monitoring purposes. Wide deployments of RFID devices will soon generate an unprecedented volume of data. Emerging applications require the RFID data to be filtered and correlated for complex pattern detection and transformed to events that provide meaningful, actionable information to end applications. In this work, we design and develop SASE, a complex event processing system that performs such datainformation transformations over real-time streams. We design a complex event language for specifying application logic for such transformation, devise new query processing techniques to efficiently implement the language, and develop …
Multi-Agent System That Attains Longevity Via Death, Megan Olsen, Hava Siegelmann
Multi-Agent System That Attains Longevity Via Death, Megan Olsen, Hava Siegelmann
Hava Siegelmann
We propose a novel approach to self-regenerating systems which require continuous operation, such as security surveillance. For that aim we introduce HADES, a self-regenerating cooperative multi-agent system with local monitoring. When agents of HADES find local failures they repair them. However, in extreme cases repair may not be possible and irregular aggressive agents will multiply. These irregular agents may use all of the system’s resources and thus take over the system. To optimize system longevity, we identify protocols for killing these irregular agents. Our primary contribution is a double communication protocol of alert and death signals among the agents, making …

Waste incineration causes unavoidable pollutant emissions to atmosphere and thus negative impact on air quality, but scale of the influence is often exaggerated. In the paper computation results of the atmospheric dispersion of pollutants were presented for one of the largest industrial and hazardous waste incineration plant existing in Poland (processing capacity: 3 ton per hour). These results confirm the fact that the incinerator meets the requirements of best available techniques (BAT) for the waste incineration and its impact on air quality is relatively small. This effect is caused mainly by proper operation of the rotary kiln incinerator, high efficiency …

Construction of the Municipal Solid Waste Incineration (MSWI) plant is considered optimal in the Programme of Management of Solid Waste in Krakow as well as in proposed scenarios of Municipal Waste Management. Evaluation of impact of the incineration plant with a capacity of 255000 tons per year on air quality in Krakow is presented in this work. The evaluation is based on assumption that air pollutant emissions from the incinerator will be at the highest allowed level resulting from emission limit values for waste incineration plants with operation time each of two planned lines 7500 hours per year. Calculation results …

Ontology Development For Context-Sensitive Decision Support, Shah Jahan Miah
Dr Shah Jahan Miah
Semantics have become acceptable techniques for data integration, data interoperability and data visualization in many software engineering domains and web developments over the past few years. This paper describes a software development where semantic ontology techniques have been used for developing a generic knowledge model applicable across rural industries. This technique enables us to outline a single access point for building end-user specific knowledge based systems. We have called the new solution prototype an End-User Enabled Design Environment (EUEDE) where the knowledge components from the problem ontology is used in building specific decision systems that are contextsensitive to end-user factors. …

Terminology management is a hot topic these days. At the tcworld conference 2006, terminology had its own forum with hundreds of participants. And a number of highly visible institutions like the LISA Terminology Special Interest Group (SIG) has been evangelizing the development and use of standardized terminology in the business world for many years.
