Investigation Of The Synthesis And Polymerization Behavior Of Vinyl Benzoate, Selim Mehmet Erhan Dec 1987

Investigation Of The Synthesis And Polymerization Behavior Of Vinyl Benzoate, Selim Mehmet Erhan

Dissertations

The goal of this study is to present a method that gives higher conversions and molecular weights for the polymerization of vinyl benzoate than obtained in previous investigations.

Polyvinyl benzoate has benzene rings attached to the backbone chain, therefore is hard and rigid. This is a characteristic which has a large application area. However previous studies in polymerizing vinyl benzoate with bulk and solution polymerizations reported low yields and troublesome crosslinking, which has limited its application. Emulsion polymerization method has the advantage of giving high polymerization rates together with high molecular weights, and therefore was chosen as the method for …

A Graphic Implementation Of Blocks World As An Example Of Artificial Intelligence, Shigenori Ochiai

Masters Theses

The objective of this study is to implement blocks world as a classic example of artificial intelligence both visually and realistically.

The visual representation is implemented by using a graphic system in a microcomputer. Real world constraints are implemented as rules concerning centers of gravity.

These goals are significant in realizing principles of artificial intelligence. Visual data help a human being to quickly understand the state of a system. Also, bringing a situation closer to the real world is a step toward to the final goal of artificial intelligence.


Kinetics Of The Metal-Exchange Reaction Between N-(2-Pyridylmethyl)Iminodiacetatonickel(N) And Copper(Ii), Kassahun W. Beyene Dec 1987

Kinetics Of The Metal-Exchange Reaction Between N-(2-Pyridylmethyl)Iminodiacetatonickel(N) And Copper(Ii), Kassahun W. Beyene

Masters Theses

The reaction between N-(2-pyridylmethyl)iminodiacetatonickel(II) and copper(II) was studied spectrophotometrically between pH 2.30 and 3.30 over a 10-fold variation in copper concentration at an ionic strength of 1.25M, and a temperature of 25.0+0.1oC. The reaction is first order in both NiPyIDA and copper(II). Terms involving proton attack and a copper dependent dissociation of the nickel complex were resolved from the data. Evidence is given for a stepwise unwrapping mechanism PyIDA from the nickel complex, followed by copper attack to give a dinuclear intermediate. A general mechanism is presented which is consistent with the kinetic data.

Comparisons to analogous nickel-aliphatic …

Theoretical Thermodynamic Properties Of Low Temperature Fluids, Zul Azhar Zahid Jamal Dec 1987

Theoretical Thermodynamic Properties Of Low Temperature Fluids, Zul Azhar Zahid Jamal

Masters Theses

The thermodynamic functions for low temperature fluids are computed using parametric integral equations and perturbation theory. Parametric integral equation N is applied to a low temperature Lennard-Jones gas. It is found that there is no significant improvement over the better known parametric integral equation C. The two parameter integral equation T is applied to a low temperature square-well potential and is found to be unsatisfactory at reduced temperatures of T*= 1.4 and 1.6, but quite accurate at T* = 2.2. The equation T results for T* = 2.2 are used as the reference system in perturbation theory computations. Tables of …


Effects Of A Magnetic Field On The Thermodynamics Of Dilute Classical Spin Chains, Guoqing Hu Dec 1987

Effects Of A Magnetic Field On The Thermodynamics Of Dilute Classical Spin Chains, Guoqing Hu

Masters Theses

The thermodynamics of a diluted chain of ferromagnetic classical spin in the presence of an external magnetic field is determined in the limit of the continuum model. The magnetization, susceptibility, specific heat are determined for both the isotropic Heisenberg and the classical XY models as functions of temperature, magnetic field and magnetic concentration. Scaling law for the behavior of the thermodynamic quantities in field, temperature, and magnetic concentration are obtained.

The calculations will be based on the continuum model of classical spin which was solved for the infinite chain system by McGurn and Scalapino.


A Seismic Reflection Survey Over The Wayne-25 Oil Field In Cass County, Michigan, Paul D. Horton Dec 1987

A Seismic Reflection Survey Over The Wayne-25 Oil Field In Cass County, Michigan, Paul D. Horton

Masters Theses

The "optimum window" seismic reflection method was used in an endeavor to further define an oil producing structure in the Traverse Limestone. This method entails using a source-geophone offset which allows desired reflections to arrive in an undisturbed time zone.

Several sources in the study area produced seismic pulses with relatively high dominant frequency components ranging from 80 to 120 hertz. However, only small charges of dynamite produced sufficient energy to penetrate the glacial drift in the study area.

Preliminarily identified reflection arrivals from the targeted horizon were consistently masked in seismic profiling records by high amplitude, low velocity seismic …

Deposition, Diagenesis, And Porosity Development Of The Middle Devonian, Lucas Formation In The West Branch Oil Field, Ogemaw County, Michigan, Scott Gregory Park Dec 1987

Deposition, Diagenesis, And Porosity Development Of The Middle Devonian, Lucas Formation In The West Branch Oil Field, Ogemaw County, Michigan, Scott Gregory Park

Masters Theses

The Lucas Formation in the West Branch Oil Field contains over 1000 feet of carbonates and evaporites deposited in restricted marine environments. Deposition ranged from a tidal flat environment (Richfield Member) to subaqueous basin central type deposition (Iutzi and Horner Members).

Early diagenesis of the Lucas Formation carbonates included dolomitization and related porosity development in certain depositional facies where physiochemical conditions were favorable. Significant porosity and permeability reduction occurred during burial resulting from anhydrite, celestite, and halite cementation. Calcite pseudopar and microspar (a neomorphic product) also reduced porosity.

Hydrocarbon production from the Lucas Formation in the West Branch Field is …
