BACKGROUND AND OBJECTIVES: The sheer volume of electrical and electronic waste (e-waste) has presently been generated in Vietnam, posing a growing concern regarding its impact can have on the environment and human health. Therefore, the need for developing policies and regulations towards the environmentally sound management of e-waste is becoming crucial. Although the municipa...

This paper proposes an efficient combination of state likelihood recycling and batch state likelihood calculation for accelerating acoustic likelihood calculation in an HMM-based speech recognizer. Recycling and batch calculation are each based on different technical approaches, i.e. the former is a purely algorithmic technique while the latter fully exploits computer architecture. To accelerat...

abstract the objective of the present study is to assess the performance of 18 irrigation districts from ten countries in the world using the benchmarking method and data mining analysis (cluster analysis). irrigation networks of dez, sefidrood, tajan and voshmgir from iran have been compared with 14 irrigation districts from nine other countries. the k- means algorithm was used to analyze the ...

Facing supply uncertainty of bulky wastes, the capacitated multi-product stochastic network design model for bulky waste recycling is proposed in this paper. The objective of this model is to minimize the first-stage total fixed costs and the expected value of the second-stage variable costs. The possibility of operation costs and transportation costs for bulky waste recycling is considered ...

high levels of weee and limited capacities for disposal and recycling, together with thenecessity to transpose the european legislation into national law have shaped the profile of weee system inromania. in order to improve the functionality of this system it is important to understand the citizens’behaviour towards weee recycling. recent research conducted in different countries suggest that v...

recycling process is one of the most important processes in the trend of sustainable development,a logical reaction against the problems that results from industrial age. building materials can play an important rolein the process of a building formation or destruction, in fact, materials forms the building nature. thus, the role ofmaterial and the impact of its recycling in sustainable develop...
