increasing population, limitation of water resources, and also enormous volume of municipal wastewater and need to dispose of these wastewaters safety, has been increased of necessity of reuse of wastewater. disposal of wastewater in soil is one of the most economical methods of their disposal. different soil characteristics, type of wastewater and method of its application are issues that affe...

abstract background: leachate produced by waste disposal sites can be contaminating groundwater. the contamination vulnerability and groundwater protection assessment has proved to be an effective tool for the delineation of protection zones in area affected by groundwater contamination. the main objective of the study is to evaluate aquifer pollution vulnerability in the new waste disposal sit...

municipal solid wastes (msws) vary in terms of quality and quantity, especially their toxic content. the efficient and sound disposal of msws not only needs implementing an integrated management procedure, but also performing a conservative way to reduce the impacts on resources. in the present research, after characterization of msw streams and consideration of disposal methods practiced in si...

background: we aimed to extract the histogram features for text analysis and, to classify the types of bio medical waste (bmw) for garbage disposal and management. methods: the given bmw was preprocessed by using the median filtering technique that efficiently reduced the noise in the image. after that, the histogram features of the filtered image were extracted with the help of proposed modifi...

Explosive ordnance disposal robot path planning is a nondeterministic polynomial time (NP) problem, traditional optimization methods are not very effective to it, which are easy to plunge into local minimum. In this paper, a new algorithm-Danger Model Immune Wavelet Neural Network (DIWNN) is improved. It is proposed to initialize the weights and biases of wavelet neural network (WNN), the ergod...
