An Investigation Of The Effects Screen Ruling And Dot Structure Have On Dot Gain On Offset Newsprint, Dawn Link

Theses

Dot gain is an inherent problem in printing on any substrate. Studies have been conducted in an effort to try to isolate the causes of the variables in the printing system to determine their influence on dot gain. The literature indicated some good reasons to suspect that course screen ruling would yield less dot gain than finer screen ruling. Investigations dealing with the effect that screen ruling has on dot gain have not yet been conducted. This study attempts to isolate the screen ruling which can yield the lowest amount of dot gain when printed on newsprint using square, round, …

Short Time Spectrum Analysis-Synthesis Of Speech, Dusan Vujcic

Theses

This thesis presents an extensive study of the short time spectrum analysis-synthesis of speech. This type of speech processing attempts to synthesize speech without the short time Fourier transform phase information. Several existing analysis-synthesis methods are presented. In addition, five other methods are attempted experimentally. The results of these experiments are explained, identifying some very important properties of the short time spectrum analysis-synthesis. One of the methods was shown to synthesize a high fidelity speech. Finally, a comparison is made between this method and other known methods which are based on short time Fourier transform approach.

Balancing Of The Shaking Force, Shaking Moment, Input Torque And Bearing Forces In Planar Four Bar Linkages, Timothy C. Hewitt

Theses

The theory, development and application of a computer program to balance the combined effects of the shaking force, shaking moment, input torque and individual bearing forces in four bar linkages is presented. The theory assumes the linkage to consist of rigid bodies, and is limited to balancing planar four bar linkages other than sliders. Balancing is accomplished using circular counterweights which are tangentially attached to the bearing joints. Counterweight sizes and locations are determined using nonlinear programming techniques where an objective function, dependent upon all the kinetic parameters, is minimized. The balancing program is capable of performing diverse functions. The …

Development Of Dynamic Testing Machine For Laboratory Modeling Of The Rock Fracturing Phenomenon, Mohammad Ali Moghaddass Zadeh Kermani

Theses

The purpose of this thesis is to develop a dynamic testing machine for laboratory modeling of the rock fracturing phenomenon. Bearing stratum fracturing is a construction difficulty which occurs when end-bearing piles are driven to weak rock or weathered sound rock. It is a pile group effect and can result in significantly less pile carrying capacity than the final driving resistance would normally indicate.

A linear scaling factor was derived to establish similitude between the laboratory apparatus and field conditions. This scaling factor is approximate and was used for overall sizing of the apparatus and its components. A more exact …

Stress In The Alveolar Bone Surrounding A Dental Implant, Jagmohan Singh Kohli

Theses

The purpose of this study is to find the stresses developed in mandibular bone due to the occlusal loading of oral endosseous blade implants. Previous work done in this area was based on the theory of "Beam on Elastic Foundation". As the width/length ratio employed is approximately 0.65, the theory of "Plate on Elastic Foundation" used in this thesis is more appropriate. The mandibular bone acts as the foundation supporting the endosseous implants.

The analysis is complicated by the fact that the implants are irregular plates of varying thickness, the foundation modulus is a variable and the occlusal loading is …

An Airborne Thermal Remote Sensing Calibration Technique, I. D. Macleod

Theses

A calibration technique for airborne thermal remote sensing systems without the requirement for ground truth or multiple altitude measure ments is developed and evaluated. This technique is based on vertical and offset look angles and in effect corrects for image degradation due to atmospheric effects . The results were evaluated by comparison to a multiple altitude regression technique using previously generated imagery, and by statistical methods, including an error analysis. Assuming that the multiple altitude regression technique was exact, the error on apparent temperature produced by this angular technique was 0.32C.

Synthesis Of Trimethylpropane-Tolylene-2,4-Diisocyanate Adduct And Its Blocked Monomers, Farhad Forohar

Theses

A trimethylolpropane adduct of tolylene-2,4-diisocyanate (TMP-TDI) was prepared by reaction in a heterogeneous solvent system. The isocyanate functional groups of the TMP-TDI adduct were blocked with the following blocking agents: p-cresol, eugenol, o-chlorophenol, and one to one mole ratio of mixtures of 2-hydroxyethyl methacrylate (HEMA) and each of the three preceding blocking agents. A sample of TMP-TDI adduct blocked with only HEMA was also prepared. The products were characterized by melting point, infrared spectroscopy, and elemental analysis. Monomers of TMP-TDI blocked with 50% HEMA and 50% blocking agents may be very useful as dental restorative materials.
