lean manufacturing is a systematic approach to identifying and eliminating wastes (non-value added activities) through continuous improvement by conveying the product at the pull of the customer in pursuit of production. in a more basic term, more value with less work. since lean manufacturing eliminates many of the problems associated with poor production scheduling and line balancing, lean ma...

in order to determine hydrological behavior and water management of sepidroud river (north of iran-guilan) the present study has focused on stream flow prediction by using artificial neural network. ten years observed inflow data (2000-2009) of sepidroud river were selected; then these data have been forecasted by using neural network. finally, predicted results are compared to the observed dat...

the aim of this study was to assess the potential impact of trout farm effluents on water quality of zaringol stream based on nsfwqi and wqi indexes. some physicochemical water quality parameters were measured from 14 point during december 2009 to september 2010 seasonality. the average value of nsfwqi is 53.21 and it shows spatial and temporal variation. the maximum value or best water quality...

pinch technology is one of the best methods for designing a multi stream heat exchanger(mshe) through a network; current pinch-based methods, however, lead to a larger and more complicateddesign problems. the major drawback of the current methods is they result in designs having more individual mshe sections than essential, correspond to the enthalpy intervals on temperature vs. enthalpy diagra...

this study was conducted to assess water quality level of zarin gol stream on macrobenthic invertebrates. macrobenthic fauna were sampled from 9 selected sampling stations along the stream with an average distance of 22 km by using a surber sampler every 45 days during the year. sampling was replicated 9 times in each sampling station. collected samples were fixed with 4% formalin, isolated, an...

an erosion hazard index methodology (ehim) was developed for assessing stream erosion. the index of stream erosion is designed as a management tool. assessing stream erosion involves consideration of a range of aspects of streams and a value judgment about a desirable state. the assessment of the erosion indicators of streams was based on a state-wide assessment of physical stream condition. a ...

water quality aspect with regard to dissolved oxygen was studied for a 24 kilometer stretch of malaprabha river in karnataka state, india. main objective of the research was to simulate the predicted dissolved oxygen depletion due to the waste load allocation in the river with the ambient observed values of dissolved oxygen, and to ascertain the application of mathematical modeling for predicti...

the present article studies one of the new methods of story narration which reviews the constant stream of thoughts and feelings inside the minds of the characters of the story. one of the basic objectives of applying this technique is having freedom in the regular elements of theme and plot. instead of codes the story is based on tangible and touchable realities so that the reader will be able...
