Perkins Green Iii: Proposed Married And Graduate Student Housing, Chou-Tein Lin

Theses

When I first came to Rochester Institute of Technology (R.I.T.) to study in the graduate program, I settled in an apartment supported by the school, because I was a new-comer and knew nothing about the surroundings. Racquet Club, a housing complex five minutes from school, is a 307-unit-townhouse-apartment, student housing area with three tennis courts and one large grass slope as its open space. I was very satisfied by this beautiful scene and thought it would be a good place to live and study. Later, however, I found sometimes, especially on weekends, there was too much noise from parties taking …

The Effect Of Flashing In Reducing The Tonal Range Of A Transparency For Photomechanical Reproduction, Bader N. Al-Hajji

Theses

Photographic processing and lithographic printing reproduction are two different processes. In photography, the transparency reproduces the original scene in continuous tone. Whereas, in lithographic printing, the reproduction is a result of an all-or-nothing process. A transparency may have a tonal range that exceeds the range that can be reproduced in lithographic printing. So tone compression is performed on transparencies that exceed the tonal range for printing. Avoiding tone compression during lithographic production results in considerable savings in cost and time. One of the methods to reduce tonal range is for the photographer to understand the relationship between emulsion flashing and …

Conversion Of Solid Ink Density And Dot Gain Specifications Into Colorimetric Specifications, Theera Tangvichachan

Theses

With the advent of the spectrophotometer as an alternative to the densitometer for pressroom applications, it becomes desirable to use a single three-color overprint halftone gray patch for controlling color on the press. As a consequence, the need for new specifications in colorimetric units, rather than SID and dot gain units, arises. The purpose of this study was to conduct a mathematical conversion of the traditional SID and dot gain specifications into the colorimetric specifications, in terms of the CIELAB coordinates. The FIPP dot gain and SID specifications were applied to the gray patch contained in the Gretag CMS3 color …

A Laboratory Study Of Ink Splitting Forces At Different Film Thicknesses And An Investigation Of The Stefan Equation, Tso-Pei Hsieh

Theses

Ink tack is a term used by printers to describe the force required to split an ink film. Such film splitting is influenced by rheological and adhesive properties as well as the internal cohesion of ink. Furthermore, the concept of ink tack in printing is associated with the forces or energy developed in the splitting of ink film at the exit of a printing nip. Stefan studied the forces required to split a thin film. He found that the force required to split a thin film is inversely proportional to the cube of the thickness of that film. This association …

The Effects Of Fluctuations In Solid Ink Density On Color Variation For Conventional And Grey Component Replacement Separations When Printing Process Color On Newsprint, Eric Matthew Pawlow

Theses

A color separation technique known as Gray Component Replacement, or GCR has been an option available to high-end drum scanner operators for the past eight years. Recently, GCR has been made available by lower-end color system vendors as well. GCR consists of removing the least predominant process color ink in a unit area, reducing the remaining colored inks by the same amount and replacing the "gray component" of the color with black ink. One of the reported benefits of the GCR technique is that more consistency can be realized during a pressrun. If this is in fact true, the first …

This paper initially discusses the impact of OSHA on retaining safety and health information, and the different areas which can benefit from computerization. It also provides guidelines to analyze existing safety …

A Thermal Desorption Modulator For Continuous Monitoring Of Volatile Organic Compounds, Yun Chen

Theses

A thermal desorption modulator is made from a short segment of thin tubing containing an adsorbent or a chromatographic stationary phase. A carrier gas containing the analyte is introduced into the analytical column through the modulator which acts as a sample trap. Rapid electrical heating of the modulator releases a "concentration pulse" of the analyte and this serves as an injection similar to that from an injection valve. The modulator also acts as a sample preconcentrator and can be used to make repetitive injections every few seconds. In this research, the mechanism of thermal desorption modulator was studied and was …

Reduction Of Acoustic Feedback Oscillations By Use Of Spectrum Shifting, Youssef Abdelilah

Theses

The problem of whistling noise or self-oscillation in public address systems operating in closed halls or rooms can be very disturbing to the listeners. This noise is sustained when the positive acoustic feedback, of the public address-room system, meets the oscillation criteria. This feedback system results from the acoustic sound signal reflected off the room walls and any other obstacles in the room, originating from the public address speakers and then re-entering the microphone.

When all of the audio signal components entering the public address system are shifted by a frequency increment Δf of 6 Hz, an increase of 5 …

Evaluation Of Truck Restrictions Using Simulation, Shaikh Mohamed Arif

Theses

Traffic congestion is a major problem in many central business districts. Many strategies have been proposed and implemented to solve or alleviate this problem. One of the most common strategies is to impose travel restrictions on the movement of trucks, without reviewing the economic consequences of goods movement restrictions on shippers, customers and on the overall business activity of the area.

This research examines the effect of various truck restrictive policies on the cost of urban goods movement, using the central business district of Manhattan as a case study. Computer simulation techniques are used to evaluate several scenarios under different …

The Permeability Of Hot Mix Asphalt Concrete With Petroleum Contaminated Soils, Kuen-Yuan Chuang

Theses

It is estimated by the United States Environmental Protection Agency (USEPA) that there are 2 to 3.5 million underground storage tanks (USTs) throughout the nation and about 25% of these tanks are leaking. The leakage of petroleum or other organic material presents serious environmental problem due to the uncontrolled release of petroleum products to ground water. Many new techniques have developed to reuse these petroleum contaminated soils generated from sites containing leaking USTs. One such soil reuse method available since 1985 is the use of petroleum contaminated soils in the production of hot mix asphalt.

The stability, durability, and hydraulic …

A Planning Model For Intermodal Auto-Rail Transportation Assignment, Daniel Disario

Theses

This thesis presents a planning model for assigning trips in a corridor served by highways and commuter rail. The underlying assumption is that commuters will choose a mode (or a combination of modes) connecting the origin and destination in a way that will either minimize their individual travel times and costs (the user equilibrium principle) or minimize total system travel time and cost (system optimal principle). The model is structured as a mathematical program with a non-linear objective function and linear constraints.

The model was applied to a case study of the Raritan Valley Corridor located in Northern New Jersey. …

Dynamics Of Blood Coagulation, Jie Gao

Theses

In this paper we present a new method to analyze whole blood coagulation dynamics. Using a PC-286 computer equipped with a DASH-16 AID board.

The row data from a SONOCLOT analyzer is amplified and digitized on the DASH-16 A/D board and stored in the PC-286 hard disk. The data is filtered through a digital Butterworth filter. The filtered data is then fit to mathematical relationship by the least square method. The coefficients which define the mathematical relationships are used to identify blood specimens with normal coagulation dynamics as distinguished from specimens with abnormal dynamics.

The digital filter and curve-fitting routine …

Stepwise Reduction And Approximation Method For Performance Analysis Of Generalized Stochastic Petri Nets, Jinming Ma

Theses

This thesis delves into the performance analysis of generalized stochastic Petri net (GSPN) model by using an approximation method: the Stepwise Reduction and Approximation (SRA) Method. The key point is that we are able to analyze a subnet in isolation by keeping its token flow direction and its sub-throughput equivalent with all the possible tokens entering into the subnet. The thesis first defines various kinds of potentially reducible subnets, subnet selection rules, approximation subnet construction rules, and reduction evaluation rules. Then corresponding to the possible subnets, the approximation method is used stepwisely until the interested measures are found with the …

Forward Kinematics Solution Of A Special Class Of General Stewart Platforms, Jian Li

Theses

A Stewart platform is a fully parallel, six-degree-of-freedom manipulator mechanism. A platform manipulator has a fixed platform acting as base, a mobile platform on which end-effector is mounted, and in-parallel kinematics chains (legs) between the two platforms. Although some direct position kinematics solutions for Stewart platforms of simplified geometry have been represented, to the best of our knowledge, no close-form direct kinematics solution for the general Stewart platform is available yet.

A common feature of six-degree-of-freedom Stewart platform of simplified geometry is the use of pairs of concentric ball joints. Due to inevitable manufacturing and assembly errors, practically there are …
