The increasing need for dynamic in-flight adjustments of a trajectory allows the airport, air traffic control and airline high degree flexibility in terms execution. This concept enables numerous optimisation options to jointly meet requirements sustainable transport increase economic ecological efficiency, as well safety. One promising measure is aircraft arrival rate prevent over-demand appro...

land use planning is a science that determines the type of land use through studying the ecological character of the land as well as its socio-economic structure. it is possible to plan for the appropriate use of the land and to enhance the present management of the land use by utilizing geographical information system (gis). to this end, our investigators identified and took steps toward devel...

Today, in the rangeland management science and determination of rangecapacity, accurate and true information about range production is crucial. In fact, rangeproduction is considered as a basis for range management. The aim of this study was tocompare different methods for the estimation of forage production with four samplingmethods in the rangelands of Kurdistan province, Iran. The sampling m...

Topology management protocols aim to minimize the number of nodes in densely distributed sensor networks that constitute the topology. Most protocols construct the topology with a fixed transmission range (i.e. maximum transmission power). However, in data transmission, it is more efficient to communicate with shorter transmission range, even with increased number of nodes in the topology. Ther...

abstract   background: pseudoarthrosis of the tibia poses one of the most challenging treatment problems in all of orthopedics. the goal of the study was to assess the clinical outcome of intramedullary rod fixation in its treatment.   methods: the results of the management for nine patients with pseudoarthrosis of the tibia with im rod fixation were reviewed retrospectively between 1986 - 2006...

This paper proposes a prototypical environment for gamut mapping in spectral space. Images are rendered in terms of light and material parameters by a symbolic ray tracer, and the parameter ranges are adjusted, without re-rendering, to bring the image into the output device’s spectral gamut. There is a growing disparity between the high dynamic range images produced by spectral renderers and th...

Context. The quest for hot dust in the central region of debris disks requires high resolution and high dynamic range imaging. Nearinfrared interferometry is a powerful means to directly detect faint emission from hot grains. Aims. We probed the first 3 AU around τCeti and Eridani with the CHARA array (Mt Wilson, USA) in order to gauge the 2 μm excess flux emanating from possible hot dust grain...

knowledge management strategy is mentioned as one of the most important success factors for implementing knowledge management. the km strategy selection is a complex decision that requires consideration of several factors. for evaluation and selection of an appropriate knowledge management strategy in organizations, many factors must be considered. the identified factors and their impact on kno...
