Fabrication Of Visible Light Emitting Diodes Soluble Semiconducting Polymers, Alan J. Heeger, David Braun Feb 1999

Fabrication Of Visible Light Emitting Diodes Soluble Semiconducting Polymers, Alan J. Heeger, David Braun

Electrical Engineering

Visible light LEDs are produced having a layer of conjugated polymer which is cast directly from solution or formed as a gel-processed admixture with a carrier polymer. The LEDs can be formed so as to emit polarized light.

Some Traffic Features At Freeway Bottlenecks, Michael J. Cassidy, Robert L. Bertini Feb 1999

Some Traffic Features At Freeway Bottlenecks, Michael J. Cassidy, Robert L. Bertini

Civil and Environmental Engineering

Observations from two freeway bottlenecks in and near Toronto, Canada indicate that the average rate vehicles discharge from a queue can be 10% lower than the flow measured prior to the queue's formation. Absent any influences from downstream, the queue discharge flows exhibited nearly stationary patterns that alternated between higher and lower rates. These alternating flow patterns were especially evident at one of the two sites, although the feature occurred at both sites during periods that immediately followed the onset of upstream queuing; i.e. a queue's formation was always accompanied by a relatively low discharge rate followed later by a …


Computer Assistance For "Discovering'' Formulas In System Engineering And Operator Theory, J. W. Helton, Mark Stankus Feb 1999

Computer Assistance For "Discovering'' Formulas In System Engineering And Operator Theory, J. W. Helton, Mark Stankus

Mathematics

The objective of this paper is two-fold. First we present a methodology for using a combination of computer assistance and human intervention to discover highly algebraic theorems in operator, matrix, and linear systems engineering theory. Since the methodology allows limited human intervention, it is slightly less rigid than an algorithm. We call it a strategy. The second objective is to illustrate the methodology by deriving four theorems. The presentation of the methodology is carried out in three steps. The first step is introducing an abstraction of the methodology which we call an idealized strategy. This abstraction facilitates a high level …


Do Law Enforcement Expenditures Crowd-Out Public Education Expenditures?, Michael L. Marlow, Alden F. Shiers Feb 1999

Do Law Enforcement Expenditures Crowd-Out Public Education Expenditures?, Michael L. Marlow, Alden F. Shiers

Economics

As state and local governments have devoted a rising share of their resources to crime-related programmes, concerns have arisen that spending on other programmes such as education will fall. Coupled with growing public concerns over performance of the public education system, and expectations that prison populations will rise as states pass and enforce more stringent sentencing laws, it is not surprising that some view the expansion of crime-related programmes as troublesome. One hypothesis is that education and crime-related programmes directly compete for government expenditures so that what one programme gains the other must lose as in a fixed-pie situation. A …


Cryptic Luminescence In The Cold-Water Fish Pathogen Vibrio Salmonicida, P. M. Fidopiastis, Henning Sørum, E. G. Ruby Feb 1999

Cryptic Luminescence In The Cold-Water Fish Pathogen Vibrio Salmonicida, P. M. Fidopiastis, Henning Sørum, E. G. Ruby

Biological Sciences

The recent discovery that the fish pathogen Vibrio salmonicida is closely related to the luminous bacteria Vibrio fischeri and Vibrio logei suggested that V. salmonicida might also be capable of bioluminescence. Interestingly, cells of V. salmonicida were found to produce light in culture, but only when exposed to either an aliphatic aldehyde and/or the major V. fischeri autoinducer N-(3-oxo-hexanoyl)-l-homoserine lactone, a transcriptional activator of the luminescence (lux) genes. An extract of spent medium of V. salmonicida that should contain any V. salmonicida acyl-homoserine lactone autoinducer, when added to V. fischeri cells, led to an induction of their …


Tax Incidence Under Oligopoly: A Comparison Of Policy Approaches, Stephen F. Hamilton Feb 1999

Tax Incidence Under Oligopoly: A Comparison Of Policy Approaches, Stephen F. Hamilton

Economics

This paper presents a methodological approach for the analysis of tax incidence that encompasses familiar forms of taxation in a general and analytically convenient model. In oligopolistic industries, the performance of a tax depends on the sensitivity of the unit tax rate to changes in industry output. Output-elastic tax schedules are less likely to be over-shifted and have superior welfare properties relative to regulatory instruments that are less responsive to the equilibrium market quantity. For revenue neutral tax reforms, the finding of Delipalla and Keen (1992) that ad valorem taxes welfare-dominate specific taxes under oligopoly is derived as a special …


Demand Shifts And Market Structure In Free-Entry Oligopoly Equilibria, Stephen F. Hamilton Feb 1999

Demand Shifts And Market Structure In Free-Entry Oligopoly Equilibria, Stephen F. Hamilton

Economics

This papers examines the structural implications of demand shifts in free-entry oligopoly equilibria. The model generalizes the conjectural variations framework to consider asymmetric firm conjectures, allows for the possibility of cost differences across firms, and endogenizes conditions of entry and exit in the industry. In non-competitive environments, changes in incumbent output and industry profitability are inversely-related to changes in the equilibrium price following a demand shift. In response to rotations of demand through the equilibrium point, changes in profitability are positively-related to changes in industry concentration and, when marginal costs are non-decreasing, inversely-related to changes in market power.


Long-Term Memory Motion-Compensated Prediction, Thomas Wiegand, Xiaozheng Zhang, Bernd Girod Feb 1999

Long-Term Memory Motion-Compensated Prediction, Thomas Wiegand, Xiaozheng Zhang, Bernd Girod

Electrical Engineering

Long-term memory motion-compensated prediction extends the spatial displacement vector utilized in block-based hybrid video coding by a variable time delay permitting the use of more frames than the previously decoded one for motion compensated prediction. The long-term memory covers several seconds of decoded frames at the encoder and decoder. The use of multiple frames for motion compensation in most cases provides significantly improved prediction gain. The variable time delay has to be transmitted as side information requiring an additional bit rate which may be prohibitive when the size of the long-term memory becomes too large. Therefore, we control the bit …

Room Temperature Fatique Response Of Γ-Tial To Impact Damage, Trevor S. Harding, J. Wayne Jones, P. S. Steif, T. M. Pollock Jan 1999

Room Temperature Fatique Response Of Γ-Tial To Impact Damage, Trevor S. Harding, J. Wayne Jones, P. S. Steif, T. M. Pollock

Materials Engineering

Gamma based titanium aluminides have received considerable attention recently as candidate materials in gas turbine applications, particularly low pressure turbine blades (1–3). Their low density and high specific stiffness, result in potentially significant weight savings in structures such as gas turbine engines if substituted for current materials. Two γ-TiAl microstructures are predominately identified in the literature: a lamellar microstructure consisting of alternating plates of γ and α2, and a duplex microstructure consisting of equiaxed γ grains and lamellar colonies (3,4). Lamellar alloys generally exhibit better fracture toughness and fatigue crack growth resistance (5–7). Duplex alloys, on the other …
