Efficient storage and handling of data stored in a peer-to-peer (P2P) network, proves vital for various applications such as query processing and data mining. This paper presents a distributed, scalable and robust layered overlay (L-overlay) to index and manage multidimensional data in a dynamic P2P network. The proposed method distinguishes between the data and peer layers, with efficient mapp...
Due to soil degradation and abundant of sediment production, the exact recognition of affecting factors on gullies erosion, and the impact of various factors on gully’s formation and development, require a more accurate study. In this regard, in the present study the length of gully, the area above headcut, headcut slope, percent of closed grain, bare soil, cover vegetation, litter, saturated e...
background institut pasteur international network (ipin), which includes 32 research institutes around the world, is a network of research and expertise to fight against infectious diseases. a scientometric approach was applied to describe research and collaboration activities of ipin. methods publications were identified using a manual search of ipin member addresses in science citation inde...
The Loess Plateau has long been suffering from serious soil erosion of which the slope-gully system is now dominant. characterized with distinctive distribution zones consisting inner and inter gully areas wherein patterns spatially vary, acting as both sediment source dominant water transport mechanism. In this paper, a substantial body research reviewed concentrating on processes control prac...
Introduction: Gully features were first observed in the images taken by MOC in impact craters, south polar pits and large martian valleys [1], tending to midlatitudes [2]. HiRISE imagery supports the conclusion that the gullies were formed by fluvial erosion [3], but the source and composition of this fluid is unclear. The superposition of the gully aprons over aeolian features, e.g. dunes, sug...
Wind erosion is one of the environmental problems worldwide, particularly in arid and semi-arid areas of Iran. Different methods and models have been proposed to measure and monitor wind erosion in the recent years. One of the accurate models for measuring f wind erosion is the USEPA model. The purpose of this study was to evaluate the quantification of wind erosion with the USEPA model and the...
