Automated Dynamic Inspection Using Active Infrared Thermography

Abstract: Active thermography is a proven technology used in a wide variety of applications. In the most common approach using a static configuration, the elements involved in the inspection do not move. This presents serious drawbacks when it is applied to the inspection of large products and machines. An alternative approach is the dynamic inspection, which enables the inspection of large and complex products with better resolution, but it is also extremely challenging as data reconstruction is necessary. This work analyzes two methods for dynamic inspection using active infrared thermography: the thermal photocopier and the line scan. Automatic robust methods are proposed to calculate the temperature–time history, producing a pseudostatic sequence that can be further processed using advanced data processing algorithms to improve defect detection. Results demonstrate the robustness of the proposed methods and the ability to inspect large products with excellent results.

Are Good Jobs Disappearing in Canada

Abstract: A paper presented at the December 2004 conference "Labor Market Developments in the United States and Canada since 2000," cosponsored by the Federal Reserve Bank of New York, the Canadian Consulate General in New York, the Centre for the Study of Living Standards, and the New York Association for Business Economics.

Increase in the Abundance of Cladocera at pH 5.1 in Experimentally-Acidified Lake 223, Experimental Lakes Area, Ontario

Abstract: Lake 223 in the Experimental Lakes Area, northwestern Ontario was experimentally-acidified with H2S0i+ from 1976 to the present. Cladocerans increased in absolute and relative abundance and in total biomass when the pH of Lake 223 was lowered from 6.7 to 5.1. Comparing the cladoceran community at pH 6.7 (1974) with that at pH 5.1 (1981 to 1983), Daphnia galeata mendotae disappeared, Diaphanosoma birgei became rare, Holopedium gibberum increased in abundance and Daphnia catawba, recorded for the first time in 1980, became abundant. Bosmina longirostris became more abundant. Except for the decline in D. birgei, the changes in cladoceran species composition with acidification are consistent with known responses of these species to low pH. The increase in importance of cladocerans in 1981 to 1983 was at the expense of copepods. It was hypothesized to be caused by the decline in predation by small fish during 1981 to 1983 as acidification reduced minnow populations and inhibited reproduction in trout and sucker. The loss of the population of the invertebrate predator, the opposum shrimp, Mysis relicta, in 1979 had little effect on cladoceran biomass.

Does Inflation Uncertainty Vary with the Level of Inflation

Abstract: L'objectif des auteurs est de tester l'hypothese que l'incertitude entourant l'inflation s'accroit lorsque le taux d'inflation augmente. Ils fondent leur analyse sur l'utilisation de modeles autoregressifs conditionnellement heteroscedastiques generalises (GARCH), lesquels permettent a la variance conditionnelle du terme d'erreur de fluctuer dans le temps. Comme cette variance constitue une approximation de l'incertitude entourant l'inflation, la detection d'une relation positive entre elle et l'inflation viendrait etayer l'hypothese examinee.

Public Capital and its Contribution to the Productivity Performance of the Canadian Business Sector

Abstract: This paper quantifies the contribution of public capital to productivity growth in the Canadian business sector. The approach developed here incorporates demand and supply forces, including the contribution of public capital, which may affect productivity performance. We estimate the model using disaggregated data composed of 37 industries in the Canadian business sector for the period 1961-2000. The results indicate that the main contributors to productivity growth, both at the industry and aggregate levels are technical change and exogenous demand (representing the effect of aggregate income and population growth). Public capital contributed for about 18% of the overall business sector multi-factor productivity growth over the 1961-2000 period. This is somewhat lower than the figures reported in the literature. However, the magnitudes of the contribution of public capital to productivity growth vary significantly across industries, with the largest impact occurring in transportation, trade and utilities.
