One of the key aims of this research is to formulate a more effective, sustainable and politically feasible pollution management approach for the Buriganga River. This was pursued through several avenues, including the analysis of river and waste water quality; the assessment of the existing river pollution control system; and the economic analysis of three alternative policies for water pollut...

POLLUTION CONTROL CACHING The bandwidth mismatch of today's high speed processors and standard DRAMS is between a factor of 10 to 50. From 1995 to the year 2000 this mismatch is expected to grow to three orders of magnitude, necessitating greater emphasis for on-chip caches. However, the cost of on-chip memory is largely a function of the chip area it requires. Today, these on-chip caches typic...

Groundwater is an important source of potable water because it is abundant and readily available in many locations and often requires little or no treatment. In 1995, groundwater accounted for approximately 20% of potable water use in the U.S., and approximately 50% of the U.S. population relied on groundwater for their source of drinking water. In most European countries, groundwater accounts ...

one major branch in mathematical sciences, which recently has been given especial attention, is optimization, including various methods such as linear programming, integer programming, and dynamic programming. due to the unique characteristics of air treatment systems, specifically multistage nature of such systems, dynamic programming has been widely applied. the purpose of this paper is to fi...

Using China’s provincial economic and pollution data from 1992 to 2008, we employ data envelope analysis (DEA) and econometric analyses to explicitly estimate technical efficiency and examine the role of technical efficiency, pollution control instruments (pollution levy and pollution quantity control), and prices of production inputs on pollution intensity. We find that an increase of labor wa...
