Dynamics Of Blood Coagulation, Jie Gao

Theses

In this paper we present a new method to analyze whole blood coagulation dynamics. Using a PC-286 computer equipped with a DASH-16 AID board.

The row data from a SONOCLOT analyzer is amplified and digitized on the DASH-16 A/D board and stored in the PC-286 hard disk. The data is filtered through a digital Butterworth filter. The filtered data is then fit to mathematical relationship by the least square method. The coefficients which define the mathematical relationships are used to identify blood specimens with normal coagulation dynamics as distinguished from specimens with abnormal dynamics.

The digital filter and curve-fitting routine …

Microwave Gaas Mesfet Nonlinearity And Large-Signal Modeling, Yan He

Theses

The nonlinearity analysis for a 0.5μm gate length microwave GaAs metal-semiconductor field-effect transistor (MESFET) by HP85150B Microwave Design System was investigated. The analysis starts with the construction of a large-signal MESFET equivalent circuit model. This model consists of bias dependent elements that were extracted by the optimization of DC and small-signal S-parameter measurement data. The details on this construction procedure are included in this work. The MESFET third-order intermodulation distortion was then simulated by HP85150B Microwave Design System. Reasonable agreement was obtained between simulation and measurement results. Microwave GaAs MESFET nonlinearity principles and large-signal modeling technique review are also presented. …

The Flow Approach To Swept Volume, Haitao Jiang

Theses

In this thesis, a method for representing swept volume based on the sweep differential equation and sweep vector field flow is developed. This method can be used to determine the boundary representation of a swept volume generated by any polygonal object undergoing a general smooth 2-D sweep. For any given sweep and object, a. set of candidate boundary points is computed using a selection criterion based on vector field behavior. The set of candidate boundary points is then trimmed in order to obtain the true boundary of the swept volume. This trimming procedure is based on some simple topological principles …

Forward Kinematics Solution Of A Special Class Of General Stewart Platforms, Jian Li

Theses

A Stewart platform is a fully parallel, six-degree-of-freedom manipulator mechanism. A platform manipulator has a fixed platform acting as base, a mobile platform on which end-effector is mounted, and in-parallel kinematics chains (legs) between the two platforms. Although some direct position kinematics solutions for Stewart platforms of simplified geometry have been represented, to the best of our knowledge, no close-form direct kinematics solution for the general Stewart platform is available yet.

A common feature of six-degree-of-freedom Stewart platform of simplified geometry is the use of pairs of concentric ball joints. Due to inevitable manufacturing and assembly errors, practically there are …

Development Of A Model For An Objective Minimum Resolvable Temperature Difference Characterization Of An Infrared Camera, Christine Issa Mourad

Theses

The parameter almost universally adopted by the infrared community for describing the overall performance of a thermal imaging camera is the minimum resolvable temperature difference. Unfortunately, this criterion is subjectively determined by a group of observers and as a consequence significantly varying results can be obtained at different times. This project describes work on an approach which ultimately aims to replace the observers by a computer-aided installation that simulates the human process by which the MRTD is estimated. The simulation is based on a direct measurement of signal to noise ratio in the image of the target and a determination …

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 …

Protocol Conformance Test Generation Using Circular Uio With Overlapping, Sesharao Patchipala

Theses

The purpose of the protocol conformance testing is to ensure that protocol implementations are consistent with their specifications. After the U-method was introduced, several test methods based on the Unique Input/Output (UI0) sequences which were the main concept in the U-method have been proposed, namely, the RCP-method, MUIO-method, MUIO with overlapping method, B-method, C-method. A good test sequence must be short and have wide fault coverage. By comparing the test sequences generated by the above test methods based on experimental results, reveals that the test sequences by the MUIO with overlapping method are the worst in quality but their lengths …

Translation Of Images On The Hypercube Using Leaf Codes, Bhavesh Patel

Theses

Image processing is used for manipulation of pictorial images. Image analysis applications are typically characterized by the need to process large quantities of image data. Some of the important transformations or operations which are car¬ried out by image processing systems are translation, scaling, superposition and rotation. Algorithms have been developed to carry out these transformations on image regions represented by quadtrees. Gargantini introduced an algorithm to translate an image region represented by a linear quadtree or leafcodes. A linear quadtree is a space efficient data structure used for storing digital images.

Teaching Moments Of Truth In Dining Room Management And Operations, Elizabeth Schaible

Theses

Educators are challenged every day to continuously improve the quality of their teaching methods in order to meet the expectations of their students, the customer. In the hospitality management department of a major urban university, the teaching of quality service in a dining room management laboratory setting lacks a formal and quantifiable feedback system to measure guest satisfaction. Such a feedback system is hypothesized to have an impact on the student's learning of quality service delivery. A literature review discusses information concerning quality service management, customer satisfaction measurement, and a detailing of a procedural and convivial service dimensions model as …

The Hotel Management Simulation/Game: An Evaluation Of Game Mechanics And Learning Outcomes, Angel E. Dominguez

Theses

Hospitality education, as a vocationally oriented field of study, must provide the student not only with theoretical concepts, but also with a series of skills that the student will use in the work place. 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 …
