Heat transfer fluids have inherently low thermal conductivity that greatly limits the heat exchange efficiency. While the effectiveness of extending surfaces and redesigning heat exchange equipments to increase the heat transfer rate has reached a limit, many research activities have been carried out attempting to improve the thermal transport properties of the fluids by adding more thermally c...

The paper studies on the core philosophy and algorithm of the designing economic mechanisms theory, a new algorithm of designing incentive compatible power market mechanisms is proposed, a generation side power market mechanism model which has features of inventive compatibility, informationally efficient and decentralized decision is constructed. The power market based on the designing economi...

Many researchers have noted that large information technology (IT) investments in the United States have not been accompanied by gains in productivity. This phenomenon has been termed the "productivity paradox". The assumption underlying this paradox is that IT should enable individuals and organizations to become more productive. The purpose of this paper is to provide insight into the results...

Data Envelopment Analysis (DEA) is a mathematic technique to evaluate the relative efficiency of a group of homogeneous decision making units (DMUs) with multiple inputs and outputs. The efficiency of each unit is measured based on its distance to the production possibility set (PPS). In this paper, the BCC model is used in output-oriented. The average return on profit as output and the covaria...

Data Envelopment Analysis (DEA) is one of the best methods for measuring the efficiency and productivity of Decision Making Units (DMU). Evaluating the efficiency of DMUs which have two or several stages by using the conventional DEA models, is equal to consider them as black box. This method, omits the effect of intermediate measure on efficiency. Therefore, just the first network inputs and t...

Government services have been privatised in Australia and many other countries, yet the transition from government ‘hierarchy’ to service delivery by non-government providers has proven to be challenging. Organizations have to deliver the same services, but they struggle to find ways to improve their performance while still conforming to government regulations. In this paper we draw upon a case...

This paper examines the profit efficiency of banks in Bangladesh using stochastic frontier analysis. The is prepared based on secondary data only and sample contains from 25 including state owned private conventional year 2011 to 2020. Translog function has been employed construct Battese Coelli 1995 (BC95) model used determine efficiency. performance reveals that, average, are 80.73% efficient...
