Context. Among optical stellar interferometers, the CHARA Array located at Mt Wilson in California offers the potential of very long baselines (up to 330 m) and the prospect of coupling multiple beam combiners. This paper presents the principle and the measured performance of VEGA, Visible spEctroGraph and polArimeter installed in September 2007 at the coherent focus of the array. Aims. With 0....

In a convincing analysis of the conditions and strength of altruism, Bester and Güth [Journal of Economic Behavior & Organization, Vol. 34, 1998, 193-209] unfortunately restrict the interpretation of their results. Their paper provides us with an analysis of the conditions and strength of malevolence (or envy) as well. ©2000 Elsevier Science B.V. All rights reserved. JEL classification: A13; C7...

background: we aimed to extract the histogram features for text analysis and, to classify the types of bio medical waste (bmw) for garbage disposal and management. methods: the given bmw was preprocessed by using the median filtering technique that efficiently reduced the noise in the image. after that, the histogram features of the filtered image were extracted with the help of proposed modifi...

introduction: fao aquacrop model (raes et al., 2009a; steduto et al., 2009) is a user-friendly and practitioner oriented type of model, because it maintains an optimal balance between accuracy, robustness, and simplicity; and it requires a relatively small number of model input parameters. the fao aquacrop model predicts crop productivity, water requirement, and water use efficiency under water...

This paper emphasizes the spatial nature of the job search process and analyzes the effects of job accessibility on search duration. A theoretical spatial job search model shows how the pattern and efficiency of job search activity may be affected by spatial labor market conditions. The empirical analysis develops unique measures of job accessibility. The results provide strong support of the s...
