In this article, stream flow effectivness is based on hydraulic network studied in the shell-side of a shell and tube heat exchange as a case study. For an appropriate heat exchangers rating design to meet a specified duty, it's better to consider each stream flow separately. Using the hydraulic network principals, a set of the correlations for calculating different stream flow rates in the cro...

Very large databases are required to store massive amounts of data that are continuously inserted and queried. Analyzing huge data sets and extracting valuable pattern in many applications are interesting for researchers. We can identify two main groups of techniques for huge data bases mining. One group refers to streaming data and applies mining techniques whereas second group attempts to sol...

25 Modeling and simulation of a network interface handling two priority levels. We propose a scheme called Double Queue Scheme to reduce the eeects of local jobs' communication on the performance of parallel jobs. It divides the only one input and output queues in traditional network interfaces into two ones. One is for the communication of parallel jobs, and the other is for the communication ...

sensitivity analysis might be considered as one of inevitable steps in modelling since it would help to determine the behaviour of model, which was developed for further application. sensitivity analysis was not paid much attention in studies that have been conducted for modelling the relationship between stream water quality and land cover except machine learning techniques such as artificial ...

the objective of this study was to diagnose integrative ecological health of an urban stream,which is located in the asian temperate region. the research approach was primarily based on the index ofbiological integrity (ibi) using fish assemblage and a qualitative habitat evaluation index (qhei). and these indexes were compared with long-term conventional chemical dataset during 1996-2005. for ...

soil detachment is known as an important process in soil erosion and its quantification is necessary to establish a basic understanding of erosion. this study was carried out to find the best flow erosivity indicator(s) for predicting detachment rate at low slopes. for this purpose, 12 experiments including 6 flow discharges (75, 100, 125, 150, 175 and 200 ml/s) and 2 slope gradients (1.5 and 2...

narration is a cognitive tool to understand the experience flow and the theses of analysis of stream of consciousness is considered as one of the most recent and popular methods of analyses of literary works. in the stream of consciousness method, for a detailed and momentum description, the content of thought has a central function and appears in the form of narrative tips and techniques like ...

Nowadays companies looking for increase of quality, flexibility and timeliness. One way to achieve these goals is lean thinking. To implementation lean production, companies are looking for waste reduction and Continuous improvement. This article Using the technology acceptance model (TAM) examined whether management accountants’ perceptions of the perceived ease of use (PEOU), or perceived use...
