Synthesis For Testability By Two-Clock Control, Shashank K. Mehta, Sharad C. Seth, Kent L. Einspahr Jan 1997

Synthesis For Testability By Two-Clock Control, Shashank K. Mehta, Sharad C. Seth, Kent L. Einspahr

School of Computing: Conference and Workshop Papers

In previous studies clock control has been inserted after design to improve the testability of a sequential circuit. In this paper we propose a two-clock control scheme that is included as a part of the logic synthesis of a finite state machine (fsm). The scheme has low area overhead and competes well with scan methods in its ability to initialize and observe circuit states. The states of the machine are assigned a pair of binary values using a novel split coding system. The purpose of the encoding is to ease navigation between any pair of states using a combination of …

Minimizing The Number Of Optical Amplifiers Needed To Support A Multi-Wavelength Optical Lan/Man, Byrav Ramamurthy, Jason Iness, Biswanath Mukherjee Jan 1997

Minimizing The Number Of Optical Amplifiers Needed To Support A Multi-Wavelength Optical Lan/Man, Byrav Ramamurthy, Jason Iness, Biswanath Mukherjee

School of Computing: Conference and Workshop Papers

Optical networks based on passive star couplers and employing wavelength-division multiplexing (WDhf) have been proposed for deployment in local and metropolitan areas. Amplifiers are required in such networks to compensate for the power losses due to splitting and attenuation. However, an optical amplifier has constraints on the maximum gain and the maximum output power it can supply; thus optical amplifier placement becomes a challenging problem. The general problem of minimizing the total amplifier count, subject to the device constraints, is a mixed-integer non-linear problem. Previous studies have attacked the amplifier placement problem by adding the “artificial” constraint that all wavelengths, …

Relations Between Directional Spectral Vegetation Indices And Leaf Area And Absorbed Radiation In Alfalfa, Elizabeth Walter-Shea, Jeffrey L. Privette, D. Cornell, Mark A. Mesarch, C. Hays

Department of Earth and Atmospheric Sciences: Faculty Publications

s ensors on satellite platforms with extreme view angles have been increasingly used to analyze regional and global vegetation cover and productivity because of frequent observations. This study, using experimental and theoretical methods, analyzed variations in vegetation indices with sun-view geometry as a means of understanding the sensitivity of relations beween vegetation indices and the biophysical properties, the leaf area index (LAI), and the instantaneous fraction of absorbed photosynthetically active radiation (fAPAR). Canopy bidirectional reflectance factors (BRFs) of an alfalfa crop were measured and simulated at a variety of solar and view zenith angles. Also, fAPAR, LAI, and leaf optical …

Prediction Of Firing Pin Shape And 3d Matching Of Shells And Firing Pins Based On Firing Pin Impressions In Primers, Donald W. Dawson, Chris Hart, Bernard S. Gilbert Iii, Rafael A. Andrade, Joel H. Blatt Jan 1997

Prediction Of Firing Pin Shape And 3d Matching Of Shells And Firing Pins Based On Firing Pin Impressions In Primers, Donald W. Dawson, Chris Hart, Bernard S. Gilbert Iii, Rafael A. Andrade, Joel H. Blatt

Aerospace, Physics, and Space Science Faculty Publications

A variable resolution video machine vision system has been built which will determine the 3-D shape of a firing pin from the dent it has made in the primer of a shell. The system can also compare primer dents in different shells and determine if a 3-D match exists. A real time optical 3-D shape recognition feature allows the operator to align the shells, determine if there is a match, and quantify the quality of the 3-D match. The system uses a laser interferometer to project variable spatial frequency structural illumination on the shells which are viewed by video cameras. …

Real Time 3-D Video Moire Inspection System With Enhanced Depth Resolution, Donald W.W. Dawson, Chris L. Hart, Bernard R. Gilbert, Gary L. Wallace, Joel H. Blatt Jan 1997

Real Time 3-D Video Moire Inspection System With Enhanced Depth Resolution, Donald W.W. Dawson, Chris L. Hart, Bernard R. Gilbert, Gary L. Wallace, Joel H. Blatt

Aerospace, Physics, and Space Science Faculty Publications

A variable resolution video machine vision systems has been built which generates twice the number of depth contours for a given grating spacing as a conventional moiré system. This variable resolution system uses a Mach-Zender interferometer to project interference fringes onto a reference surface and onto a target surface. Video images of the two structurally illuminated surfaces are mixed in a video mixer with the resulting output being moiré contours which are the intersections of the two surfaces. If the reference surface is a flat plate, we get equal depth contours of the target surface, and if the reference surface …

Design Considerations For A Small Ultraviolet-Visible Space Telescope For Amateur And Professional Use, Donald Platt Jan 1997

Design Considerations For A Small Ultraviolet-Visible Space Telescope For Amateur And Professional Use, Donald Platt

Aerospace, Physics, and Space Science Faculty Publications

Presented is a preliminary design for a small ultraviolet- visible (uv-vis) sensitive space telescope. Included will be optical, sensor, and spacecraft subsystem design considerations. With recent advances in charge coupled device (CCD) technology it is now possible to build a space telescope system with wavelength sensitivity from 200 to 1000 nm. A main objective of this design is to keep costs to a minimum and use commercial off the shelf (COTS) components wherever possible. Such a low-cost system could provide a platform for studying such untested techniques as small space-based optical interferometry. The observatory could be open to a guest …

Analysis Of Scanning Tunneling Optical Spectroscopy Applied To Narrow Gap Semiconductors, James D. Patterson, James G. Mantovani Jan 1997

Analysis Of Scanning Tunneling Optical Spectroscopy Applied To Narrow Gap Semiconductors, James D. Patterson, James G. Mantovani

Aerospace, Physics, and Space Science Faculty Publications

Homogeneous II-VI narrow gap semiconducting alloys are of interest because of their use in infrared detectors. These compound semiconductor materials are inherently difficult to grow in bulk due to gravity induced convective flows. A microgravity growth environment has therefore been considered. In order to evaluate the quality of crystals grown in space compared to those grown on the ground, it is necessary to characterize both. One important aspect of this characterization is the study of stoichiometry, x. A characterization scheme using scanning tunneling optical spectroscopy (STOS) involves determining the spectral response of the photoexcited tunneling current for a semiconductor. By …

Volumetric Exchanges Between A Managed Marsh And A Coastal Estuary, Ashok Pandit, John H. White, Antonis A. Kakoullis, Satish B. Akula, James R. David Jan 1997

Volumetric Exchanges Between A Managed Marsh And A Coastal Estuary, Ashok Pandit, John H. White, Antonis A. Kakoullis, Satish B. Akula, James R. David

Mechanical and Civil Engineering Faculty Publications

The dominant term in the estimation of net flux calculation, between a marsh and a source of tidal water is often the exchange of water. The purpose of this study was to provide a description of the methodology used to estimate the volumetric exchange of surface waters between a managed marsh and the Indian River Lagoon during the managed and unmanaged periods. The paper also documents the simplifying assumptions that had to be made to estimate the exchanges both during the managed and unmanaged period. These assumptions had to be made either because the data were limited mainly due to …

The Synthetic A Priori Proposition Of Kant's Ethical Philosophy, Nelson T. Potter Jr. Jan 1997

The Synthetic A Priori Proposition Of Kant's Ethical Philosophy, Nelson T. Potter Jr.

Department of Philosophy: Faculty Publications

I will consider Kant's claim that the categorical imperative (CI) is a synthetic a priori proposition. We know from the first Critique that such propositions are likely to be very important, but also difficult to justify. Kant says exactly the same things about the CI in the Grundlegung: the CI is difficult to justify2, but if we do not succeed in justifying it, morality may be a mere "phantom of the brain.',3 Though little has been written on this topic, a correct understanding of this claim is important to understanding Kant's views.

Magnetic Response Of Fef2 Films On (100) Mgo (Abstract), Shireen Adenwalla, G. P. Felcher, J. Nogués, I. K. Schuller Jan 1997

Magnetic Response Of Fef2 Films On (100) Mgo (Abstract), Shireen Adenwalla, G. P. Felcher, J. Nogués, I. K. Schuller

Shireen Adenwalla Papers

Pairs of FeF2/Fe films show large exchange bias. In bulk FeF2 is antiferromagnetically ordered below 78 K, and the magnetic moments of the corner and center atoms in the rutile structure are respectively parallel and antiparallel to the tetragonal axis. Are the moments compensated in a thin film as well, or does a net magnetization develop, for instance at the interface with iron? A polarized neutron reflection measurement was taken on a single film of FeF2, 920 Å thick, grown in the (110) orientation on a MgO (100) face. In polarized neutron reflection is measured …

Convolution And Fourier-Feynman Transforms, Chull Park, David Skough Jan 1997

Convolution And Fourier-Feynman Transforms, Chull Park, David Skough

Department of Mathematics: Faculty Publications

In this paper, for a class of funtionals on Wiener space of the form F(x) = exp{∫T0 f(t, x(t)) dt}, we show that the Fourier-Feynman transform of the convolution product is a product of Fourier-Feynman transforms. This allows us to compute the transform of the convolution product without computing the convolution product.

Temperature Transfer Due To Induction Sealing, Scott Evans Jan 1997

Temperature Transfer Due To Induction Sealing, Scott Evans

Theses

This thesis investigates the temperature recorded during the induction sealing process within the headspace of a container. The topic for this thesis stemmed from a question of whether or not the product inside an induction sealed bottle has the potential of being adversely affected by heat generated during the induction sealing process on a packaging line during production. The thesis demonstrated the heat generated and temperature recorded utilizing irreversible chemical temperature indicating labels during the induction sealing process on a standard bottle packaging line with an aluminum foil liner/innerseal. Based on the results of this study, the following trends were …

Factoring Integers Defined By Second And Third Order Recurrence Relations, Kirk Ocke Jan 1997

Factoring Integers Defined By Second And Third Order Recurrence Relations, Kirk Ocke

Theses

Factoring the first two-hundred and fifty Fibonacci numbers using just trial division would take an unreasonable amount of time. Instead the problem must be attacked using modern factorization algorithms. We look not only at the Fibonacci numbers, but also at factoring integers defined by other second and third order recurrence relations. Specifically we include the Fibonacci, Tribonacci and Lucas numbers. We have verified the known factorizations of first 382 Fibonacci numbers and the first 185 Lucas numbers, we also completely factored the first 311 Tribonacci numbers.

A Study Of Package Drops In Global Distribution Environment, Donald Appleton Jan 1997

A Study Of Package Drops In Global Distribution Environment, Donald Appleton

Theses

The focus of this study was to compile and interpret drop heights and drop frequencies data for small parcel packages moving through the Eastman Kodak Company global distribution network. The need for this study arose from the inclusion of drop height probability curves into Kodak's shipping tests for packaged product weighing less than 100 lb. Kodak packaging engineers suspected the drop heights included in the probability curves were too high in drop height and too many in frequency when compared to the actual distribution environment. The data for this study resulted from dozens of test shipments using dummy-load packages throughout …

The Effect Of Cyclic Environment On The Compression Strength Of Curtain Coated Corrugated Containers, Paijit Sangchai Jan 1997

The Effect Of Cyclic Environment On The Compression Strength Of Curtain Coated Corrugated Containers, Paijit Sangchai

Theses

Cyclic changes in temperature and humidity in real-life distribution environments decrease BCT and life-span of standard corrugated containers. As a result, BCT obtained from testing at standard TAPPI environment may be inadequate to protect the products inside from damages during real-life distribution. The corrugated containers users need to understand this concept in order to design a proper corrugated containers at a cost-efficient price that can retain BCT in these extreme temperature and humidity changes environments. Wax curtain coating is one of the most commonly used techniques to retain BCT of corrugated containers that are distributed in short-term high humidity environment, …
