A Dynamic Model Of A Fill-And-Draw Reactor And Its Implications For Hazardous Waste Treatment, Shing-Hwa Chang

Theses

A dynamic model of a fill-and-draw reactor has been developed, which includes a number of operational parameters such as the draw-down volume, the fraction of total cycle time devoted to fill, reaction, and draw, and the concentration of the toxic substance in the feed to the reactor. The model has been solved numerically for two cases, one assuming Monod kinetics, and one considering substrate inhibition (Andrews kinetics).

The conversions achieved with this type of reactor have been compared to that of a conventional activated sludge (CSTR) design. These results indicate that for most practical settings of the operating parameters, the …

Temperature Dependent Reliability Of Plastic Packaged Microcircuits, Wasim Ahmed

Theses

Increasing power and power densities in new high complexity semiconductor devices are creating heat removal problems. Increased powers produce higher junction temperature which lead to potentially faster degradation of device reliability. Thermal management at device level packaging involves efficient and cost-effective removal of dissipated thermal energy from the device to assure its reliable performance over the long term. In the context of very high levels of integeration of future ICs, thermal management will mean making such devices possible close to the limits of acceptable high temperature.

The major factors affecting heat flow in a plastic Dual-in-line-packages (DIP'S) are investigated using …

A Model For Estimating The Cost Of Developing An Expert System, Louis Vincent De Troia

Theses

This paper describes a model that can be used to assist engineers and managers in estimating the cost of developing an expert system. Numerous models are available for estimating the cost of developing conventional software systems [1] [2] [3]. However, relatively little work has been done in the area of expert systems cost estimation [3] [4].

Estimating the cost of any software development project is a difficult task, yet software developers are required to provide reliable estimates of the cost of development early in the development life cycle, quite often before many of the system requirements have been defined. While …

Comparison Between Edge Tracing And Slit Tracing In The Measurement Of The Otf, J. S. Perron

Theses

A study was performed to compare two methods of measuring the Optical Transfer Function (OTF), namely edge tracing and slit tracing, to evaluate the performances and limitations of each method. Edge tracing is a very common method of measuring the OTF of an optical system. It is simple to set up, but the sampling size is limited and derivation of the Edge Spread Function is required in order to obtain the Line Spread Function (LSF). This derivation induces considerable high frequency noise. A competing method, slit tracing, is more complex mainly because of physical limitations such as the actual slit …

Effects Of Exposure On The Printing Characteristics Of The Association Product Process, Claude David Davis

Theses

The investigation examined the printing characteristics of the association product plate, a continuous tone lithographic process which utilizes a synthetic, light-sensitive coating variably ink-receptive according to the degree of exposure it receives. The methodology was designed to determine (1) the printing range of the plate, (2) the effective sensitivity of the coating to varying amounts of exposure within this range, and (3) the degree to which adherence to ideal tone reproduction could be achieved through systematic variation of exposure. The plate is not commercially available, therefore it was necessary to consult patent literature and prior research to obtain details of …

The Application Of Cie Lab To Study Trapping Efficiency, Patchanee Malikhao

Theses

It has been known that apparent trapping percentages caused by changing printing sequence (or printing order) affect the color appearance of the overprint areas. However, no other studies in the past were done in a standard color measurement system- that is the CIE system. This thesis was conducted in order to learn how the selected printing sequences yellow- magenta-cyan-black, black-cyan-magenta-yellow, yellow-magenta-cyan-black, and cyan-magenta-yellow-black- of a monotack process ink yield the color gamuts on the CIE LAB color space. Since the two sequences: yellow-magenta-cyan-black and cyan-magenta-yellow-black, were recommended to be adopted as standard sequences for SWOP inks, this reseach attempted to …

Morphological Analysis Of Microvessels Using High Voltage Electron Microscopy (Hvem), Ibm Personal Computer And 3-D Reconstruction Software, Wieslaw Slawomir Krajewski

Theses

The mesenteric arterioles (outer diameter < 100 µ) from a normotensive and a hypertensive dog were perfused in situ, excised, post-fixed and embedded in Spurr medium block. Thick serial cross sections (0.5 µ) of the vessels were obtained from hand formed mesas and placed on Formvar coated slot grids.

The cross sections were subjected to High Voltage Electron Microscopy (HVEM) and five or more electronmicrographs were taken to cover the individual cross sections. The prints of electronmicrographs were linearly enlarged (3X) and made into photomontages of sections. The membrane contours in the montages were traced on transparent overlays, producing polygons which in turn were traced on GTCO digitizing pad. All polygons were labeled, color coded and stored in IBM PC's filing system. The vessels were reconstructed from up to 100 whole cross sections and subjected to cell compartmentalvolume analysis. The reconstructed images can be …

Optimal Design Aspects Of A Unit Treating Hazardous Wastes Via Biodegradation : A Theoretical Approach, Farnaz Saghafi

Theses

The treatment of wastes via biodegradation is a widely utilized technique in most industries today. The kinetics of biodegradation, in most cases, follow either the Monod (non-inhibitory) or Andrews (also known as Haldane, inhibitory) model as indicated by published experimental data. The present study investigates aspects of the optimal design of a unit treating wastes when the biodegradation kinetics are those mentioned above. The criterion of optimality is the minimum volume achieving a desired conversion under given load conditions.
