A Non-Invasive Technique For Burn Area Measurement, Jong-Daw Yu May 1989

A Non-Invasive Technique For Burn Area Measurement, Jong-Daw Yu

Theses

The need for a reliable and accurate method for assessing the surface area of burn wounds currently exists in the branch of medicine involved with burn care and treatment. The percentage of the surface area is of critical importance in evaluating fluid replacement amounts and nutritional support during the 24 hours of postburn therapy. A noninvasive technique has been developed which facilitates the measurement of burn area. The method we shall describe is an inexpensive technique to measure the burn areas accurately.

Our imaging system is based on a technique known as structured light. Most structured light computer imaging systems ...

Hydrogel Ocular Inserts For The Treatment Of Infectious Bovine Keratoconjunctivitis , Je-Phil Ryoo Jan 1989

Hydrogel Ocular Inserts For The Treatment Of Infectious Bovine Keratoconjunctivitis , Je-Phil Ryoo

Retrospective Theses and Dissertations

Hydrogel coated ring shaped ocular inserts (containing the antibiotic, tylosin tartrate) were used in an evaluation of the effectiveness of polymeric ocular drug release devices for treating infectious bovine keratoconjunctivitis. Two major in vivo tests were done: a treatment test using infected cattle and a test to evaluate ring retention characteristics. The in vivo experiments represent the first experiments using hydrogel ocular inserts containing an antibiotic for treating infectious bovine keratoconjunctivitis;The bacterium, Moraxella bovis, was used to replicate the disease. In the infection tests, ten calves were challenged with 2.4 x 10[superscript]8 - 1.6 x 10 ...


Design Of A Portable Microprocessor-Based International Phonetic Alphabet (Ipa) Text-To-Speech Conversion Device For Use By The Speech Impaired , Dexter Katsutoshi Ishii Jan 1989

Design Of A Portable Microprocessor-Based International Phonetic Alphabet (Ipa) Text-To-Speech Conversion Device For Use By The Speech Impaired , Dexter Katsutoshi Ishii

Retrospective Theses and Dissertations

A portable microprocessor-based alternate communication device was designed and a prototype fabricated. This device allows speech impaired individuals, whose language skills remain intact, to input and edit an utterance of unrestricted vocabulary via a keyboard/LCD display system. The utterance, which is specified using the International Phonetic Alphabet (IPA), is then converted into an appropriate set of speech synthesizer parameters, using context sensitive rules. An interrupt driven system is used to pass each set of parameters, in order and at the appropriate time, to the synthesizer, thus generating an audible output;Tests conducted using the device in its present state ...


Organ Doses In Routine Radiographic Procedures, Yang Han Jan 1989

Organ Doses In Routine Radiographic Procedures, Yang Han

Theses and Dissertations

There is general agreement that the extent of the risk from x-ray examination is related in some way to the radiation dose. As the dose increases, the likelihood of significant biological effects also increases. If a clear correlation between dose and effect is to be established, a convenient and reasonably accurate method of estimating patient’s absorbed doses during common radiographic examinations will be highly needed. A simple method is developed in this project to determine the two important parameters e exposure at skin entrance (ESE) and half value layer (IIVL), which is essential to get reasonably accurate estimates of ...
