A Direct Method For Surface Structure Recovering Based On Uoff, Ping Lin

Theses

The unified optical flow field (UOFF) theory which can be used for estimating motion and recovering surface structure was recently established in [9, 10]. The direct method developed in [2, 3, 4, 6, 7] does not need to explicitly solve the optical flow field and to find feature correspondence. Based on the UOFF, a direct method in space domain is developed to reconstruct the curved surface structure characterized by an Nth degree polynomial equation from a pair of stereo images. The initial work on this new method was reported in [8, 11].

In this study, I basically work on simulation …

In this paper, two composite models which model both User Equilibrium and System Optimal assignments are presented. The composite models are solved using the GAMS (General Algebraic Modeling System) software, a powerful mathematical programming tool. The first model was based on Beckman's Formulation, (Beckman, …

A Petri Net Toolkit For Parallel Program Debugging, Potla Kishore Reddy

Theses

An effective debugger must support the language and operating system resource abstractions that are available to the programmer. Earlier debuggers worked at the machine architecture level: they dealt with machine instructions and registers. Current debuggers, designed for single process debugging, permit access to program variables and breakpoints and single-stepping at the level of high-level language statements. Eventhough the current debuggers, are already implemented to be a powerful tool, they still cannot do a job of parallel debugger.

In this thesis, a computer simulation system has been established by Petri Nets execution providing a convenient and friendly interface as it allows …

A Thermal Desorption Modulator For Continuous Monitoring Of Volatile Organic Compounds, Yun Chen

Theses

A thermal desorption modulator is made from a short segment of thin tubing containing an adsorbent or a chromatographic stationary phase. A carrier gas containing the analyte is introduced into the analytical column through the modulator which acts as a sample trap. Rapid electrical heating of the modulator releases a "concentration pulse" of the analyte and this serves as an injection similar to that from an injection valve. The modulator also acts as a sample preconcentrator and can be used to make repetitive injections every few seconds. In this research, the mechanism of thermal desorption modulator was studied and was …

These skills include problem analysis and decision making, team building, and the relationship of the hotel business variables (Occupancy, Profits and Guest Satisfaction). Simulation gaming techniques are thought to be very effective methods to develop these skills. In simulations participants imitate actions required on the job and are actively involved in the processes of learning and skills acquisition. The Hotel Management Simulation/Game is a simulation technique …

Prelude To Teambuilding: The Nature Of Modernity, Fred Klein

Theses

Professional management defines itself by the particularistic (dominant) view that shapes the form and conduct of its activities. Modern management theory and practice is primarily the outcome of the greater espoused views of positivistic science. This has permeated a conscription to an attitude that is considered "factually" appropos to conduct research and inquiry. "Reality" has thus become categorized to derivatives of Newtonian science. While there is no disputation that this perspective and its conjointed methodology has a basis in the confluences that interact on materialistic reality (objective world), newer insights dispute its absolutistic form. The principle import of the newer …
