Modeling and analysis of competing dynamic ecological systems

Kuang, Yan January 1900 (has links)
Doctor of Philosophy / Department of Industrial & Manufacturing Systems Engineering / David H. Ben-Arieh / The dynamic relationship between competing ecological systems has long been and will continue to be one of vital topics in both ecology and mathematical ecology because of its importance and universal existence. Mathematical modeling has become an effective tool to model and simulate the dynamic system, providing decision makers with strategy recommendations. Although a great amount of previous work has attempted to model the biological mechanisms including dispersal, only rarely has there been a systematic investigation on different spatial effects. The author introduces spatial games as a modeling approach with different constructions towards different dynamic systems in order to benefit from the systematic research on spatial dynamics when studying the competing ecological systems. This research developed models of two systems: (1) two-spotted spider mite prey-predator system; (2) tomato spotted wilt virus (TSWV) and west flower thrips (WFT) vector-borne disease system. For two-spotted spider mite system, the author presented four spatial mathematical models as well as a novel spatial game model to describe the spatial movement of two competing species. For the TSWV-WFT system, a spatial game was introduced to describe the spatial dynamics of adult thrips and the novel model was validated with experimental data. The author also gave suggestions for efficiently controlling the vector-borne disease by performing sensitivity analysis towards parameters. The major contribution of this research is to introduce spatial games as a tool to describe the dynamic schemes in ecological systems. Compared to a traditional dynamic model, a spatial game model is more expressive and informative. This approach uses a payoff function and a movement probability function that can be adjusted based on habits, characteristics and mobility schemes of different competing entities, which has enriched its modeling power. The methodology and modeling approach used in this dissertation can be applied to other competing species dynamic systems, and have a broad impact on research areas related to mathematical ecology, biology modeling, epidemiology, pest control, vector-borne disease control, and ecological decision-making processes.

Teaching functions through modeling

Barlow, Brittany Kristine 08 April 2013 (has links)
This report discusses topics relating to modeling functions. The pedagogical content knowledge of student teachers and expert teachers and its effect on their ability to teach through modeling is examined. An observed modeling lesson is presented. To conclude, there will be a discussion about the pitfalls of using calculators in modeling and exploration lessons. / text

Wire and column modeling

Mandal, Esan 30 September 2004 (has links)
The goal of this thesis is to introduce new methods to create intricate perforated shapes in a computing environment. Modeling shapes with a large number of holes and handles, while requiring minimal human interaction, is an unsolved research problem in computer graphics. In this thesis, we have developed two methods for interactively modeling such shapes. Both methods developed create perforated shapes by building a framework of tube like elements, such that each edge of a given mesh is replaced by a pipe. The first method called Wire modeling replaces each edge with a pipe that has a square cross-section. The result looks like a shape that is created by a framework of matchsticks. The second method, called Column modeling allows more rounded cross-sections for the pipes. The cross-sections can be any uniform polygon, and the users are able to control the number of the segments in the cross-section. These methods are implemented as an extension to an existing modeling system guaranteeing that the pipes are connected and the resulting shape can be physically constructed. Our methods require an initial input mesh that can either be imported from a commercially available software package, or created directly in this modeling system. The system also allows the users to export the models in obj file format, so that the models can be animated and rendered in other software packages.

A Study on the Architecture-Oriented Process Model

Lee, Chung-Chyi 20 June 2006 (has links)
ABSTRACT The contemporary business operations are encountering tremendous challenges. The management of the globalization, such as the supply chain management, makes the enterprise to consider making alliances, establishing the partner relationships and forming the virtual enterprise. At this time, when an enterprise wants to sustain a competitive advantage, a business process with adaptation and facilitation to support the operations of the organization is necessary. Therefore, a good modeling in business process can get value-added to the enterprise. There are a lot of techniques for business process modeling. Each technique of modeling has its advantages and disadvantages. This paper presents a technique of architecture-oriented process modeling, which is an integrated model with structure and process in one unity. In order to show the excellent performances of the architecture-oriented process model, a comparison was made between the architecture-oriented process model and those traditional process models. It is shown that the architecture-oriented process model has the merits of the capability to satisfy not only the functional, behavioral, organizational, and informational perspectives of modeling an enterprise, but also the concurrency and executable ability. Finally, two cases are presented to explain the abilities of this model. The architecture-oriented modeling is thriving, the author believes that the continuing discussions and investigations will have a great beneficiary to the total solution of the problems of the varied environments of the business operations and thereof.

Crowd modeling: generation of a fully articulated crowd of characters

Swaminathan, Karthik 12 April 2006 (has links)
In this thesis I present a fast, efficient, and production friendly method to generate a crowd of fully articulated characters. A wide variety of characters can be created from a relatively few base models. The models that are generated are anatomically different from each another, while maintaining the same topology. They all have individual characteristics and features, that distinguish them from the others in the crowd. This method is easily adaptable to different kinds of characters, from hyper-realistic characters to highly stylized characters, and from human characters to insects like spiders. The crowd character models generated by this method are fully articulated and are ready to be animated.
