Since few years Map Reduce programming model have shown great success in processing huge amount of data. Map Reduce is a framework for data-intensive distributed computing of batch jobs. This data-intensive processing creates skew in Map Reduce framework and degrades performance by great value. This leads to greatly varying execution time for the Map Reduce jobs. Due to this varying execution t...

This paper describes the aspect map approach to model the processing of geographic maps. Geographic maps are described as spatial representation media which play an important role in many processes of human spatial cognition. We focus on the aspectuality of representation and therefore deal with aspect maps: spatial organization structures in which one or more aspects of geographic entities are...

Medical image processing is one of the most demanding domains of the computing sciences. The importance of the domain is in terms of the CPU and the memory requirements that shall be used by the system to compute the result. Moreover, the volume of the data is often very large in terms of the space and primarily requires many processing tools. At the same time, the tools have to be available as...

This study investigated whether brain neural activity that accompanied the processing of previously learned map information was influenced by the modality in which the spatial parameters of the maps were originally learned. Participants learned a map by either viewing it directly or by reading an equivalent verbal description. Following learning, the participants' ability to use their spatial k...

this research was carried out based on systematic analysis approach for evaluation of ecological resources capability of kasilian representative catchment for agricultural land use. the study area is located in southern of mazandaran province. in this study we used topography digital data, paper maps, climatology data, satellite images and gis, database and spreadsheet software. the process of ...

in order to capability investigation on landsat-7 satellite etm+ data in separability forest type and mapping in the zagros region, a small window digital data dating july 2001 from ghalajeh forests in the kermanshah province were analyzed. ground data were provided the cluster sampling method and with 0.36 ha. no radiometric error was found then the quality investigations. orthorectification w...

In this study, isothermal single-pass forming doformation of forged 18CrNiMo7-6 alloy steel was carried out by Gleeble-3500 thermal simulation testing machine. The constitutive equations and processing maps with parameters deformation temperature strain rate were established. results show that the optimum hot are 1050 °C, 0.1 s–1 peak power efficiency being 0.432. mechanism grain refinement dur...
