A Sql Front-End Semantic Data Model, Marc Richard Lodico Jan 1989

A Sql Front-End Semantic Data Model, Marc Richard Lodico

Theses

SQLSDM is a "front end" semantic data model to a SQL relational database management system (RDBMS). SQLSDM provides a more semantically complete RDBMS through the implementation of a Domain and Relational Integrity scheme. SQLSDM provides integrity definition functions and a sub-system to interpret SQL commands . Integrity system tables are created through the use of SQLSDM ' s domain definition command and SQL ' s "CREATE TABLE" command. As SQL database update commands are interpreted, SQLSDM uses these integrity tables to enforce domain and referential integrity. SQLSDM operates virtually transparent to the user and provides for greater database consistency and …


Structural Aspects Of Bis(Quadridentate)Zirconium(Iv) Complexes, Brian P. Cleary Jan 1989

Structural Aspects Of Bis(Quadridentate)Zirconium(Iv) Complexes, Brian P. Cleary

Theses

The synthesis of bis(quadridentate)-zirconium (IV) complexes was completed of which two new complexes, bis(N,N'-disalicylidene-cis-1,2,diamino-cyclohexane( zirconium (IV) and bis(N,N'disalicylidene-trans-1,2-diaminocyclohexane)zirconium(IV), were deemed suitable for physical and chemical comparisons to bis(N,N'-disalicylidene-1,2-phenylenediamino)-zirconium(IV). Using H-NMR spectroscopy at low temperatures, it was determined that the interconversion of the cyclohexane moiety of bis(N,N'disalicylidene-cis-1,2-diaminocyclohexane) zirconium(IV) begins to slow whereas, the motions associated with the backbones of the other two complexes do not. Furthermore, using H-NMR spectroscopy, it was determined that heating solutions of pairs of the complexes for four days at 155 C causes the complex to exchange ligands to form mixed-ligand complexes.

Modeling Of Elastic-Viscoplastic Bahavior And Its Finite Element Implementation, Ted Diehl Dec 1988

Modeling Of Elastic-Viscoplastic Bahavior And Its Finite Element Implementation, Ted Diehl

Theses

A state variable approach is developed to simulate the isothermal quasi-static mechanical behavior of elastic- viscoplastic materials subject to small deformations. Modeling of monotonic/cyclic loading, strain-rate effect, work hardening, creep, and stress relaxation are investigated. Development of the constitutive equations is based upon Hooke's law, the separation of the total strain into elastic and plastic quantities, and the separation of work hardening into isotropic and kinematic quantities. The formulation consists of three coupled differential equations; a power law measuring viscoplastic strain-rate and two first order equations for isotropic and kinematic hardening. Derivation of, behavior of, and use of the model …

Spine Preparation: Factors Affecting Optimum Linkage Of Paper And Adhesive In Adhesive Bookbinding, Richard Adams Nov 1988

Spine Preparation: Factors Affecting Optimum Linkage Of Paper And Adhesive In Adhesive Bookbinding, Richard Adams

Theses

Adhesive bookbinding, a method of holding trimmed pages together in a book using hotmelt glue, offers rapid binding and curing time, but has the disadvantage of poor glue penetration into the paper edges. A weak binding will result unless good linkage can be made between paper and glue, which is the objective of spine-roughening treatments. Eight spine-roughening treatments from three manufacturers were compared on an uncoated and a coated paper stock, against a control treatment of trimmed paper. Treatments were studied by light- and scanning electron microscopic examination of paper edges and by measurement of the mean page-pull values based …


Building And Testing A Gravure Paper Conformity Tester, Cort Holland Oct 1988

Building And Testing A Gravure Paper Conformity Tester, Cort Holland

Theses

The gravure industry does not have an inexpensive tester which can accurately predict the behavior of paper on a gravure press. The most acceptable tester currently available is the Parker Print Surf. A "conformity" tester, based on compression of paper into a thin channel, was designed and built. It was compared to the Parker Print Surf and found to be poorer in predicting ability except in the special case of groundwood papers. More study is necessary. Several unusual techniques were used. The first involved running sheets of paper through a web press. This technique had a slight "leading" sample distortion …

A Study Of Gravure Cell Structure Generated By The Hell Chromagraph 399 Er Laser Scanner Onto A Photopolymer Plastic Gravure Printing Surface, Wichian Ekataksin Oct 1988

A Study Of Gravure Cell Structure Generated By The Hell Chromagraph 399 Er Laser Scanner Onto A Photopolymer Plastic Gravure Printing Surface, Wichian Ekataksin

Theses

It is known that the gravure process provides the best quality printed materials and the fastest production speed. The gravure process, as a matter of fact, is the only process which can utilize fully digital imaging technology. For instance, the Helio-Klischograph Model K201 and K202 incorporated with the Hell Chromacom System can engrave gravure cylinders directly without using any halftone films or bromides. Hell Co., Ltd., moreover, has been developing the electron beam engraving technique which employs digital imaging technology to engrave gravure cylinders. On the other hand, Crosfield Electronics Co., Ltd. introduced the Lasergravure process which also utilizes digital …


A Study Of The Effect Of Surround And Ambient Lighting Conditions On Crt Screen Colors, Diane Ouellette Oct 1988

A Study Of The Effect Of Surround And Ambient Lighting Conditions On Crt Screen Colors, Diane Ouellette

Theses

The use of CRT monitors as a soft copy proof in color electronic pre-press systems (CEPS) has become common. This has raised some question as to the appropriate viewing conditions for such terminals. This writing discusses the effects of ambient illumination as well as screen surround conditions on optical, psychophysical, and physical characteristics of CRT colors in a complex color field. A review of related literature, specifically those studies of chromatic adaptation, and effects of surround conditions on brightness, hue, and saturation is included. These studies are compared to the experimental data and both an ambient light model and surround …

A Study On The Relationship Of The Moisture Content Of Paper And The Setoff Rate Of Drying Oil Lithographic Ink And Its Application To Thermographic Printing, Daniel Gibbons Sep 1988

A Study On The Relationship Of The Moisture Content Of Paper And The Setoff Rate Of Drying Oil Lithographic Ink And Its Application To Thermographic Printing, Daniel Gibbons

Theses

The focus of this study was to determine the specific moisture content of several different papers that were exposed to four different relative humidity environments at approximately 30 degrees centigrade. This was done in order to see if the amount of water present in a sheet of paper affects the drying rate of drying oil inks. This in turn was done so that we would be able to determine if the rate at which this ink dries and its corresponding increase in viscosity affected the tack or "stickiness" which is vital to thermographic printing applications. The addition of moisture to …
