Railway efficiency. Metodological aspects

Iran Railway Efficiency Analysis, Using DEA: An International Comparison

Efficiency measurement is critical for industries where firms do not face strong competition, as we cannot rely on the market to discipline the firms' efficiency. Railway is a typical example. At the same time the fact that railway produces multiple outputs using the common set of inputs calls for a delicate and sophisticated treatment in measuring the efficiencies. In this article, the DEA ...

not be disappointed. Mr. Page has the satisfaction of finding that the views which he then expressed as to the nature and pathogeny of these affections, and which were in strong divergence from those most widely prevalent at that time (1883), have met with general acceptance not only in this country, but by foreign writers also. His subsequent experience has served to confirm his former opinion...

Thermodynamic Aspects of Precipitation Efficiency

Precipitation efficiency is one of important meteorological parameters and has been widely used in operational precipitation forecasts (e.g., Doswell et al., 1996). Precipitation efficiency has been defined as the ratio of precipitation rate to the sum of all precipitation sources from water vapor budget (e.g., Auer and Marwitz, 1968; Heymsfield and Schotz, 1985; Chong and Hauser, 1989; Dowell ...
