An Efficiency Comparison of Different Java Technologies

Java and related technologies are very used for distributed applications today. In this moment, there are many Java technologies using the client-server paradigm. Among these, the following are the most important: Common Gateway Interface (CGI) [4,7], Servlets/JSP [1,10,12], JavaSpaces [1,5,6] and Enterprise Java Beans (EJB) [1,2,8]. To choose one of these for solving a problem (to implement a ...

Economic Efficiency of Agricultural Production In Brazil

This study measures levels of technical, allocative and economic efficiency in agricultural crop production for Brazil in 1995. A nonparametric frontier model (DEA) under constant returns to scale was used. On average, the results suggest that the sector suffers from moderate technical inefficiency and from strong allocative inefficiency. If full technical efficiency were achieved, the crop pro...

Potential bioethanol and biogas production using lignocellulosic biomass from winter rye, oilseed rape and faba bean

To meet the increasing need for bioenergy several raw materials have to be considered for the production of e.g. bioethanol and biogas. In this study, three lignocellulosic raw materials were studied, i.e. (1) winter rye straw (Secale cereale L), (2) oilseed rape straw (Brassica napus L.) and (3) faba bean straw (Viciafaba L.). Their composition with regard to cellulose, hemicellulose, lignin, ...

Estimation of cost efficiency for firms in different technologies using data envelopment analysis

Data envelopment analysis (DEA) is a method for evaluating the relative efficiency of a set of firms in a production process. Estimation of cost efficiency is one of the branches of performance evaluation. Cost efficiency evaluates the ability of producing current output with minimum available cost. Now let's assume that there are several groups of firms that operate separately and have differe...
