Real-time american sign language recognition using desk and wearable computer based video
- IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE
, 1998
"... We present two real-time hidden Markov model-based systems for recognizing sentence-level continuous American Sign Language (ASL) using a single camera to track the user’s unadorned hands. The first system observes the user from a desk mounted camera and achieves 92 percent word accuracy. The secon ..."

Expected Time Bounds for Selection
, 1975
"... A new selection algorithm is presented which is shown to be very efficient on the average, both theoretically and practically. The number of comparisons used to select the ith smallest of n numbers is n q- min(i,n--i) q- o(n). A lower bound within 9 percent of the above formula is also derived. ..."

Cache memories
- ACM Computing Surveys
, 1982
"... Cache memories are used in modern, medium and high-speed CPUs to hold temporarily those portions of the contents of main memory which are {believed to be) currently in use. Since instructions and data in cache memories can usually be referenced in 10 to 25 percent of the time required to access main ..."

The Labor Demand Curve is Downward Sloping: Reexamining the Impact of Immigration on the Labor Market
- THE QUARTERLY JOURNAL OF ECONOMICS
, 2003
"... Immigration is not evenly balanced across groups of workers that have the same education but differ in their work experience, and the nature of the supply imbalance changes over time. This paper develops a new approach for estimating the labor market impact of immigration by exploiting this variatio ..."

How much should we trust differences-in-differences estimates?
, 2003
"... Most papers that employ Differences-in-Differences estimation (DD) use many years of data and focus on serially correlated outcomes but ignore that the resulting standard errors are inconsistent. To illustrate the severity of this issue, we randomly generate placebo laws in state-level data on femal ..."

at the 5 percent level for up to 45 percent of the placebo interventions. We use Monte Carlo simulations to investigate how well existing methods help solve this problem. Econometric corrections that place a specific parametric form on the time-series process do not perform well. Bootstrap (taking
Receiver-driven Layered Multicast
, 1996
"... State of the art, real-time, rate-adaptive, multimedia applications adjust their transmission rate to match the available network capacity. Unfortunately, this source-based rate-adaptation performs poorly in a heterogeneous multicast environment because there is no single target rate — the conflicti ..."

Why Do Americans Work So Much More than Europeans?”, Quarterly Review of the Federal Reserve Bank of Minneapolis,
, 2004
"... Abstract Americans now work 50 percent more than do the Germans, French, and Italians. This was not the case in the early 1970s, when the Western Europeans worked more than Americans. This article examines the role of taxes in accounting for the differences in labor supply across time and across co ..."

Binary Vuong Test Percent Times Model 1 Chosen
, 2011
"... 1 Comparison with Standard Approaches Within each simulation study conducted in Section 4 of the manuscript, we also examine the performance of the standard model selection procedures commonly used in the literature; the Bayesian Information Criterion (BIC) (Schwarz, 1978) and the Vuong test (Vuong, ..."

plot the percentage of times Model 1 is chosen given that one of the two models is selected. Both methods tend to support one model disproportionately when the mixture probability, π1 is close to 0 or 1. For example, if 80 % of observations were generated by Model 1 and 20 % by Model 2, both methods
The Determinants of Credit Spread Changes.
- Journal of Finance
, 2001
"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

The distinction between changes in credit spreads and changes in corporate yields is significant: while an adjusted R 2 of 60 percent is obtained when regressing high
Time-varying NAIRU and its implications for Economic Policy
- NBER WORKING PAPER
, 1996
"... This paper estimates the NAIRU (standing for the non-accelerating Inflation Rate of unemployment) as a parameter that varies over time. The NAIRU is the unemployment rate that is consistent with a constant rate of inflation. Its value is determined in an econometric model in which the inflation rate ..."
