Image Enhancement And Analysis Of Leukocyte Adhesion, Yee-Ruh Lin
Image Enhancement And Analysis Of Leukocyte Adhesion, Yee-Ruh Lin
Theses
The image of leukocyte adhesion to microvascular walls in the isolated rat perfused heart model has been observed and processed. Some of the fluorescent labeled leukocytes are barely visible due to microscope focal plane and the motion of objects. The purpose of this thesis is to extract leukocyte from the image of the experimental data using image enhancement and analysis (segmentation) techniques and develop a program to handle automatically counting of leukocytes in a predefined scene.
Burn Wound Healing Evaluation By Infrared Imaging, Shang-Yuan Chen
Burn Wound Healing Evaluation By Infrared Imaging, Shang-Yuan Chen
Theses
Infrared imaging is a pictorial method of temperature representation. Its advantage in the treatment of burns is that it is a non-invasive, safe and reliable method for estimating the area, temperature and depth of burns. An Imaging Burn program was developed for comparing changes in burn area in response to treatment with time. The program proved itself capable of determining the surface area of simulated lesions on the skin of human volunteers to within an error of 1.6 percent. The size and temperature of burn lesions in patients was recorded. First degree burns were warmer than surrounding areas of normal …
The Application Of Adaptive Step-Size Control In The Numerical Simulation Of Calcium Release In Vascular Smooth Muscle, Michael John Sydor
The Application Of Adaptive Step-Size Control In The Numerical Simulation Of Calcium Release In Vascular Smooth Muscle, Michael John Sydor
Theses
An algorithm for the adaptive control of numerical integration step-size is developed and implemented for the simulation of a three compartment model for Vascular Smooth Muscle. The three compartment model accounts for the simultaneous diffusion of Ca, 45Ca, EGTA, Ca-EGTA, and 45Ca-EGTA, and is an extension of a two compartment model by Diecke for the simultaneous diffusion of Ca, EGTA, and Ca-EGTA. The addition of the third compartment is to account for the presence of the Sarcoplasmic Reticulum which stores the calcium needed for contraction and is the primary regulator of calcium in the VSM cell. The SR …
Eeg Data Compression, Yun-Chu Wu
Eeg Data Compression, Yun-Chu Wu
Theses
This paper presents two different ways to compress EEC data-direct data com pression and a data transformation technique. The Adaptive Delta modulation and Huffman coding are used in the former method to predict or interpolate the data. Linear orthognal transformation algorithms are used in the latter method to detect and reduce the redundancies of the data by analyzing the spectral and energy distribution. Each method is implemented by programming the computer. The experimental results of their efficiencies and errors with different requirements and under different situations are compared and discussed. By comparing the EEC data compression degree and normalized square …
