Simulations Of Passive Matrix Polymer Image Sensors, David Braun, G. Yu Apr 1999

Simulations Of Passive Matrix Polymer Image Sensors, David Braun, G. Yu

Electrical Engineering

Two-dimensional passive photodiode matrices are hardly useful for image sensing due to the crosstalk between pixels. This crosstalk makes it difficult to recover information from individual pixels. A switching unit attached to each sensing unit has been the common solution in image sensors (such as in CMOS sensors and in TFT-PiN a-Si photosensors). A novel organic photodiode with voltage-switchable photosensitivity was developed recently. Passive photodiode matrices made with such organic photodiodes can be used for image sensing applications. This circuit simulation study demonstrates an effective scheme to extract images from passive photodiode matrices, concluding that individual photodiode parameters determine the …

A Calibration Procedure Using Topmodel To Determine Suitability For Evaluating Potential Climate Change Effects On Water Yield, Brian Dietterick, James A. Lynch, Edward S. Corbett Apr 1999

A Calibration Procedure Using Topmodel To Determine Suitability For Evaluating Potential Climate Change Effects On Water Yield, Brian Dietterick, James A. Lynch, Edward S. Corbett

Natural Resources Management and Environmental Sciences

An evaluation was conducted on three forested upland watersheds in the northeastern U.S. to test the suitability of TOPMODEL for predicting water yield over a wide range of climatic scenarios. The analysis provides insight of the usefulness of TOPMODEL as a predictive tool for future assessments of potential long-term changes in water yield as a result of changes in global climate. The evaluation was conducted by developing a calibration procedure to simulate a range of climatic extremes using historical temperature, precipitation, and streamfiow records for years having wet, average, and dry precipitation amounts from the Leading Ridge (Pennsylvania), Fernow (West …

A Quantitative Method For Estimating Probable Public Costs Of Hurricanes, Michael R. Boswell, Robert E. Deyle, Richard A. Smith, E. Jay Baker Apr 1999

A Quantitative Method For Estimating Probable Public Costs Of Hurricanes, Michael R. Boswell, Robert E. Deyle, Richard A. Smith, E. Jay Baker

City and Regional Planning

A method is presented for estimating probable public costs resulting from damage caused by hurricanes, measured as local government expenditures approved for reimbursement under the Stafford Act Section 406 Public Assistance Program. The method employs a multivariate model developed through multiple regression analysis of an array of independent variables that measure meteorological, socioeconomic, and physical conditions related to the landfall of hurricanes within a local government jurisdiction. From the regression analysis we chose a log–log (base 10) model that explains 74% of the variance in the expenditure data using population and wind speed as predictors. We illustrate application of the …

Environmental Imperatives Reconsidered, Terry L. Jones, Gary M. Brown, L. Mark Raab, Janet L. Mcvickar, W. Geoffrey Spaulding, Douglas J. Kennett, Andrew York, Phillip L. Walker

Social Sciences

Review of late Holocene paleoenvironmental and cultural sequences from four regions of western North America shows striking correlations between drought and changes in subsistence, population, exchange, health, and interpersonal violence during the Medieval Climatic Anomaly (a.d. 800–1350). While ultimate causality is difficult to identify in the archaeological record, synchrony of the environmental and cultural changes and the negative character of many human responses—increased interpersonal violence, deterioration of long-distance exchange relationships, and regional abandonments—suggest widespread demographic crises caused by decreased environmental productivity. The medieval droughts occurred at a unique juncture in the demographic history of western North America when unusually large …

Capacity-Demand-Diagram Methods For Estimating Seismic Deformation Of Inelastic Structures: Sdf Systems, Anil K. Chopra, Rakesh K. Goel Apr 1999

Capacity-Demand-Diagram Methods For Estimating Seismic Deformation Of Inelastic Structures: Sdf Systems, Anil K. Chopra, Rakesh K. Goel

Civil and Environmental Engineering

The ATC-40 and FEMA-274 documents contain simplified nonlinear analysis procedures to determine the displacement demand imposed on a building expected to deform inelastically. The Nonlinear Static Procedure in these documents, based on the capacity spectrum method, involves several approximations: The lateral force distribution for pushover analysis and conversion of these results to the capacity diagram are based only on the fundamental vibration mode of the elastic system. The earthquake-induced deformation of an inelastic SDF system is estimated by an iterative method requiring analysis of a sequence of equivalent linear systems, thus avoiding the dynamic analysis of the inelastic SDF system. …

An Analysis Of The Factors That Influence Student Performance: A Fresh Approach To An Old Debate, Sanjiv Jaggia, Alison Kelly-Hawke Apr 1999

An Analysis Of The Factors That Influence Student Performance: A Fresh Approach To An Old Debate, Sanjiv Jaggia, Alison Kelly-Hawke

Economics

There is a general consensus that student performance at all levels has been deteriorating. Despite numerous attempts by researchers to link school expenditures with student performance, a clear relationship does not exist. Since a number of difficulties plague earlier studies, this paper attempts to remedy these problems by offering a better data design and a sounder methodology. This study uses the 1992 Massachusetts Educational Assessment Program (MEAP) test scores from 4th, 8th, and 12th grade students to measure student performance. Since each students grade falls into one of five possible categories, the application of an ordered log it model incorporates …

On Exchange Rates And Economic Growth, Eric O'N. Fisher Apr 1999

On Exchange Rates And Economic Growth, Eric O'N. Fisher

Economics

Extending Ireland's (1994) model, this paper analyzes an international economy where cash or credit can be used for payment. Foreign trade credit is more costly than its domestic analog. A depreciation of the real exchange rate is associated with an external surplus and a reduced share of imports purchased with credit. Economic growth slows when foreign trade credit becomes the predominant means of payment for international transactions. A country with high inflation exports its Tobin effect and thus temporarily increases world growth.

Development And Reproduction Of A Population Of Eretmocerus Eremicus (Hymenoptera: Aphelinidae) On Bemisia Argentifolii (Homoptera: Aleyrodidae), David H. Headrick, Thomas S. Bellows, Jr., Thomas M. Perring Apr 1999

Development And Reproduction Of A Population Of Eretmocerus Eremicus (Hymenoptera: Aphelinidae) On Bemisia Argentifolii (Homoptera: Aleyrodidae), David H. Headrick, Thomas S. Bellows, Jr., Thomas M. Perring

Horticulture and Crop Science

Although the aphelinid parasitoid Eretmocerus eremicus Rose & Zolnerowich is the most abundant naturally occurring parasitoid of Bemisia argentifolii Bellows & Perring in the U.S. desert southwest, its effectiveness in different cropping systems varies. Development and reproduction of a population of this parasitoid attacking B. argentifolii infesting cotton, Gossypium hirsutum L., and sweet potato, Ipomoea batatas L., were quantified and compared. Females potato; there were no significant differences of these parameters between host plant species. A preoviposition period of 0.61 d was recorded, and a maximum number of eggs laid in a day was 69 on cotton and 13 on …

Calculation Of Population Attributable Risk For Alcohol And Breast Cancer (United States), Marilyn Tseng, Clarice R. Weinberg, David M. Umbach, Matthew P. Longnecker Apr 1999

Calculation Of Population Attributable Risk For Alcohol And Breast Cancer (United States), Marilyn Tseng, Clarice R. Weinberg, David M. Umbach, Matthew P. Longnecker

Kinesiology and Public Health

Objectives: Because of increasing evidence that alcohol may be causally associated with breast cancer, we reconsider the population attributable risk (PAR) for alcohol and breast cancer for the US adult female population using an effect estimate from a meta- analysis and incorporating a revised perspective on measurement error correction. Methods: To estimate PAR, we employed a formula appropriate to use with an adjusted effect estimate. To estimate intermediate quantities needed to apply that formula, we used adjusted relative risk estimates from a previously published meta- analysis, as well as SEER cancer statistics and general population data from the third National …

Reviews Of Atomic Audit: The Costs And Consequences Of Us Nuclear Weapons Since 1940 By Stephen Schwartz; And Killing Detente: The Right Attacks The Cia By Anne Cahn, David W. Hafemeister

Physics

Science aims to link cause and effect for natural phenomena. Linking cause and effect for historical events is often more difficult since historical events cannot be tested by rerunning history with varied parameters. Despite the difficulty, it is worthwhile to review the causes behind the magnitude of the U.S. nuclear buildup. Two critical questions should guide this analysis: How much of the $5.8 trillion (1996 dollars) that the U.S spent to build 70,000 nuclear warheads, deployed on 75,000 missiles and 8600 bombers, was too much? And, was the effectiveness of the Soviet military exaggerated with false predictions? These two books …
