Drag Reduction In Pipe Flows With Polymer Additives, Daniel W. Grabowski

Theses

Polyethylene Oxides (PEO) with molecular weights of 4 and 6 million and a Polyacrylamide (PAM) with a molecular weight of 15 million, were added to a turbulent pipe flow (15000 < Re < 50000) for drag reduction. The polymer was injected directly into the test section in one scenario, premixed in a tank and then pumped through the test section in the second. The injection addition method was found to be optimal because it subjected the polymer to lower amounts of shear stresses than the premixed addition method. A maximum of 75% reduction in drag was obtained. Even trace concentrations, as low as 2.5 WPPM (weight parts per million) , resulted in as high as 37% reduction in drag. Long thin high molecular weight polymers (PEO) were more effective than coiled high molecular weight polymer (PAM) . For the same molecular structure it was found that the polymer with heavier molecules had better drag reducing characteristics. The polymer with coiled molecules, however, is more resistant to shear stresses which break down the polymer into smaller less effective molecules. It was found that there is a critical concentration for the greatest drag reduction. This concentration is approximately 375 WPPM (.0375% byweight) of PEO for the injection method, and 500 WPPM of PEO for the premixed method. At greater concentrations, the viscosity of the solution increases such that the drag reduction characteristics of the polymer can no longer compensate.

Ray Tracing For Constructive Solid Modeling, Anju Sharma Mccanna

Theses

This thesis describes a system for the creation and realistic depiction of non-geometric, complex, three dimensional solid models by utilizing a ray tracing algorithm and a graphics relational database. Geometric primitives such as a sphere, cylinder, block, and cone are combined together by using the Boolean set operations of union (+), intersection (&), and difference (-). The three dimensional solid models are built based on the concept of constructive solid geometric modeling. The database provides functions for the creation, transformation, and deletion of the primitives and models. A model may be displayed as a wireframe for a fast display or …

Crt-Based Dialogs: Theory And Design, Jonathan Levine

Theses

CRT (cathode ray tube) based, direct selection dialogs for computing machines and systems were apparently a cure for issues like ease of learning and ease of use. But unforeseen ~ and probably unforeseeable problems arose as increasingly sophisticated systems and dialogs were developed. This paper describes some of the emerging problems in CRT-based dialog design, develops theories about why they occur, and discusses potential solutions for them as a basis for future research. This investigation also provides a survey of the research into what makes programming and programming languages difficult, and what makes them simple.

Mechanical Properties Of Polymeric Packaging Films After Radiation Sterilization, Viriya Pungthong

Theses

The use of radiation as a sterilization process is increasing. The well-developed technology of the radiation sterilization as applied to medical devices has assured the food industry that the process is reliable. Due to the food industry's possibility of widespread use, it is especially crucial that an appropriate packaging material be chosen so that its integrity is maintained after irradiation. This is because the commercial food packaging process carries products through more rigorous paths and channels than medical supplies. Many polymers used in the medical field show various degrees of degradation after radiation exposure, which can be determined either by …

Penthesilea: Woman As Hero, George Totskas

Theses

It is my intention to create a visual epic drama with a woman as its hero. This Female hero will go through a journey that will metaphorically correspond to points of conflict of womanhood (through the ages) with institutions of power. The viewer is called to interact with the artwork on an aesthetic level first. Then he/she is invited to explore the story line - a combination of the artwork. Finally, the viewer is challenged to interpret the drama by using the titles of each individual piece.

Expert Systems In Typography, David B. Fisher

Theses

Electronic publishing systems are providing authors with a tremendous amount of power formerly only available to printers: the choice of typographic design and layout. However, many authors use this power without the proper background, with potentially disastrous results. We have developed a prototype expert system that provides users of electronic publishing systems with the printer's knowledge in computer form in one narrow area of the publishing field to aid them in preparing their publications.

San Luis Rey In The Nineteenth Century: Its People, Institutions And Events, Robert Ernest Melbourne

Theses

Anyone interested in the history of San Luis Rey will soon realize that the San Luis Rey of the nineteenth century was a region of considerable expanse. The Mission of San Luis Rey de Francia, which was just getting on solid footing at the beginning of 1800, established ranchos for the raising of cattle, sheep and grain that provided the revenue to sustain the Mission and most of the food for the nearly three thousand Indian residents. These ranchos, which included gardens and orchards of varying sizes, extended from the Rancho Agua Hedionda in the south to Rancho Santa Margarita …

Aqueous Absorption Of Nox Induced By Sodium Chlorite Oxidation, Chen-Lu Yang

Theses

Aqueous scrubbing in alkaline media for the removal of nitrogen oxides (NO_x) from flue gases using NaClO₂ as an oxidant is being investigated in the Chemical Engineering Department of New Jersey Institute of Technology. This thesis presents the findings of an experimental program that was conducted to estimate the capability of NaClO₂ aqueous solution to oxidize insoluble NO to soluble NO₂ in order to increase its solubility and thus prevent NO_x emission from entering the atmosphere from flue gases emitted by municipal incinerators or power plants.

The key findings of this program are:

Fourier Image Synthesis And Slope Spectrum Analysis Of Deepwater, Wind-Wave Scenes Viewed At Brewster's Angle, Jan Arthur North

Theses

A semi-empirical model for the Fourier synthesis of deepwater, wind-wave scenes has been constructed for the analysis of water-wave slope spectra. The main simplifying assumptions of this model are 1) fully-developed wind-wave surfaces are quasi-homogeneous, quasi -stationary and are therefore treatable by Fourier methods, 2) the subsurface is both optically and mechanically deep, and 3) the small range of spectral wave components defines a fetch-limited, small amplitude condition. A nonlinear transformation of wave slope to reflected and refracted radiance in both horizontal and vertical polarizations was effected under the special conditions of Brewster-angle viewing under clear skies at a spectral …

Determination Of Trace Amounts Of Lead, Cadium And Zinc In Vegetables Using Differential Pulse Polarography, Elizabeth Franca-Romitti

Theses

Toxic metals are present in foods to greater or lesser extention as contaminants, as a result of increasing industrialization, and associated pollution of the biosphere. Lead and cadmium are well known toxic metals which accumulate into the body causing harmful effects at low concentration levels especially in children. Zinc, on the other hand, is an essential micronutrient, but larger levels in foods can be considered toxic.

Twenty eight brands of vegetables including canned, glass packed, frozen and fresh vegetables were analyzed for Pb, Cd, and Zn, in tomatoes, carrots, mushrooms and asparagus. The technique used was Differential Pulse Polarography (DPP) …

Visual System Modeling And System Response Analysis, Zhongquan Li

Theses

Based on the anatomical structure, a structural model of the visual system was established. System responses of different stimulations were analyzed based on the model. More extensive study was made on the system impulse response. A mathematical model with parameters representing prominent process components was developed to represent the system response in a compact form and the parameters were statistically studied to correlate to the real physiological characteristics of the visual system. The parameters of the model were used to fit the system intensity response function. The result shows that it is a more quantitative way to construct the system …

The Effects Of Degraded Indoor Air Quality On Employees Working In High Rise Office Buildings, Richard Patrick Luongo

Theses

An examination of the effects of poor indoor air quality on workers in high rise office buildings was conducted. These effects are manifested physiologically, psychologically and economically and originate from sources inside and outside the building, as well as from the building's ventilation system. These sources include combustion products, microorganisms, volatile organic chemicals, cigarette smoke and miscellaneous chemicals. Lower productivity and higher absenteeism are the initial results of these effects. If the situation becomes chronic, an erosion of trust between employer and employee can occur which may eventually serve as the basis for litigation, such as worker's compensation claims and …

Survival Rate Study Of Intrashock Versus Postshock Microwave Rewarming In Rats Subjected To Hemorrhagic Shock, Hani M. Patel

Theses

In search for a more effective treatment for rewarming of profound accidental hypothermia, a comparative survival rate study was conducted of intrashock versus postshock microwave rewarming in rats subjected to hemorrhagic shock. In an anechoic chamber, rats were illuminated with 50 Watts of continuous microwave power supplied by a 915 MHz microwave generator. This frequency corresponds to a free-space wavelength of about 33 cm. The incident-power density was calculated to be about 8.5 mW/cm2, and the whole-body specific absorption rate (SAR) was calculated to be 14.5 W/kg.

The microwave postshock group showed a significantly higher post shock survival rate than …
