the potential risk of metal accumulation in periurban agricultural areas is a matter for concern.the climate characteristics and carbonate content of calcareous agricultural mediterranean soils typical inthese areas favour metal accumulation at the surface level; however there is also a risk of potential metalmobility. our study focuses on the soil properties affecting metal mobility in these s...

Routing Protocol performance is strongly affected by user or node mobility in Mobile Ad hoc Network. Performance of any routing protocol for Mobile Ad Hoc Network is investigated and assessed using simulator. Network Simulator 2 uses various mobility models to mimic mobility patterns. Simulating a precise real life user/node mobility pattern is difficult. The ns-2 mobility models attempt throug...

In this paper we analyze eight years of employment data of a regional grocery store chain in the U.S. The data include job titles, wage rates, and earnings for all employees. We examine initial job assignments, mobility between departments, and mobility into supervisory and management positions in the firm. We model the flows of individuals between different departments and jobs within the firm...

MANET is class of an emerging technology of ad hoc networks. Ad hoc networks can be built around any wireless technology, including infrared, global positioning system (GPS), radio frequency (RF) and so on. Each node in a MANET is free to move freely in any direction, and therefore it will change its links to other devices frequently. Mobility model shows how the speed and direction of a node c...

sand dunes mobility is one of the serious problems in arid regions. since wind regime is one of the important factors in sand dunes formation, its frequency, direction and magnitude can be effective. amount of wind energy and its directional variability (wind regime) have significant control on the morphology and maintenance of aeolian landforms. by recognizing of morphometric and morphodynamic...

Vehicular Ad-hoc Network (VANETs) is a derived version of Mobile Ad-hoc Network (MANETs). They are on its own conFigure. d infrastructure-less network. They provide communication facility between vehicle to vehicle (VV) and vehicle to infrastructure (V-I). Vehicles follow different mobility patterns due to variations in speed. As vehicles have high mobility and dynamic topology; the tendency of...

In this work we explore the effects of human mobility on the dispersion of a vector borne disease. We combine an already presented stochastic model for dengue with a simple representation of the daily motion of humans on a schematic city of 20 × 20 blocks with 100 inhabitants in each block. The pattern of motion of the individuals is described in terms of complex networks in which links connect...

We formulate the optimum personal paging area problem as an interval estimation problem, with an aim to reduce the paging signaling cost by minimizing the size of the paging area. A paging algorithm is developed to set-up the optimal one-step paging area that contains the locations of a mobile user with a high probability and thus to gain a coverage that is matched to the user’s time-varying mo...

In this paper, the author studies the application of network user behavior data mining under the background of big data. In this research work we focused mainly on the precise mobility profile building thorough trajectory and behavioral pattern mining using the GSM CGI Cell-ID, where all the concerned issues like precise spatial extraction, stay points detection and mobility profiling are addre...
