This study develops a cartographic index of forest stands vigour from Ikonos imagery data. The study area located at GOUNAMITZ (New-Brunswick, Canada) consists mainly of fir, tolerant and intolerant hardwoods at mature and overmature stages. Forest inventory plots were set up in the stands; dendrometric measures (height, DBH, annual increment, etc.) were… (More)
This study is devoted to the prediction of pollutant formation inside combustion chambers. In order to control minor species emissions, considering the high sensitivity of kinetic chemistry to temperature, it is required that physical analysis include detailed description of all heat transfer processes. As far as radiation is concerned, one may state that… (More)
The African Spur tortoise, Geochelone sulcata, has been introduced to Costa Rica. A total of 31 tortoises were measured for 26 gross morphometry parameters. All individuals measured were inmature, aged from 5 to 34 months, and were born in captivity in La Garita de Alajuela, Costa Rica. Mean straight carapace length was 83.1 mm, mean straight plastron… (More)
Let D be the unit disk in the complex plane C. We prove that for any polynomial p of degree at most n max z ∈ * D p(z) − p(¯ z) z − ¯ z n max 0 j n p e ij /n + p e −ij /n 2 , where * D denotes the boundary of D. We show how this result is related to classical inequalities of Bernstein and Markov and to more recent results due to Duffin and Schaeffer.
