This paper analyzes the efficiency of the Brazilian banking sector over the post-privatization period of 2000-2007. We employ a Bayesian stochastic frontier approach, which provides exact efficiency estimates and confidence intervals and thus, allows an accurate comparison across institutions and bank groups. The results suggest that large banks are the most cost and profit efficient, supportin...

Data Envelopment Analysis (DEA) is widely used in banking sector to measure the efficiency of the banks. This paper evaluates the performance of the banks in India using cost, revenue and profit models of DEA and comes out with a comprehensive efficiency index for banks, by combing the efficiency scores of various DEA models, using the Shannon entropy. In general, the banks included in this stu...

A coordinate plane representation of the resource requirements of digital modulation methods is presented, and an overall resource efficiency measure is proposed. This measure can be used for the comparison of digital modulation methods and the evaluation of an emerging modulation technique. Several typical digital modulation methods are compared based on this measure to show its validity. key ...

The research investigates the link between market concentration and efficiency by analyzing Greek olive oil industry data from 2006 to 2014. Unlike previous on this issue, which focused impact of overall company power, we study association three types firm (profit, technical, scale) concentration. Our theoretical framework assumptions were not predefined but generated modelling sector through m...

The DVB-H standard is developed by ETSI to broadcast digital videos to handheld devices, but data loss is a critical issue due to the broadcast behavior. On the other hand, DVB-IPDC integrates DVB-H with an IP-based wireless network to provide bidirectional communication. We adopt this wireless network to deal with data retransmission and call it a recovery network. The paper argues that networ...

Article history: Received 14 September 2005 Received in revised form 10 December 2005 Accepted 19 December 2005 Available online 14 February 2006 There has been a growing concern about the interactions of endangered sea turtles with the pelagic longline fishery in Hawaii recently. Some tough measures including a swordfish harvest ban have been put into effect since 2000 to protect these turtles...

Water Splitting I is a significant task to cover the residential energy demand of a society (approximately 20% of the total) with solar energy, but it is a much greater challenge to cover all of it, including the demands of industry, commerce, and transportation. The 20% goal may be achievable through photovoltaic-powered households and appliances, but the 100% goal will require extensive facil...
