The delay-tolerant networks (DTN) are networks that support communication between nodes when connectivity is intermittent, due to the difficulties encountered in this type of environment, such as node mobility frequently changing network topology, this which does not allow to route messages directly between the source and destination, the routing algorithms must consider mobility to increase th...

Well-established fine-scale urban mobility models today depend on detailed but cumbersome and expensive travel surveys for their calibration. Not much is known, however, about the set of mechanisms needed to generate complete mobility profiles if only using passive datasets with mostly sparse traces of individuals. In this study, we present a mechanistic modeling framework (TimeGeo) that effect...

conclusions a short-term wbv exercise improves isotonic strength of the leg muscle and dynamic balance, while creatine supplementation with and without wbv training increases isometric strength of the leg muscle and mobility in elderly women. background a decline in neuromuscular function can cause a decrease in physical fitness in elderly women. objective the present study aimed at investigati...

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...

in this study, a rapid, simple and sensitive ion mobility spectrometry (ims) method with corona discharge as ionization source was described for the morphine determination in human urine. morphine was extracted and purified from urine samples using solid phase extraction procedure with c18 column. it can offer the clean extracts which no extra peaks were observed in ims. under operating experim...

The effect of compost and humic acid in mobility and concentration of cadmium and chromium in contaminated soil were investigated. Experiment was carried out with three levels of soil cadmium and chromium and two organic matters (compost and humic acid). The study was performed in a randomized complete block design with 3 replicates. Results indicated that application of organic substances enha...

Social networks have been resorted to as effective platforms for social mobility in many parts of the world. This mobility occurs when social media users exploit their interpersonal relationships, especially their ‘weak ties’ (Granovetter, 1973). Social networks enable their users to be producers of information, rather than mere consumers, and to be socially and politically well-informed. They ...

Mobile Adhoc Network is a kind of wireless ad hoc network where nodes are connected wirelessly and the network is self configuring. MANET may work in a standalone manner or may be a part of another network. In this paper we have compared Random Walk Mobility Model and Random Waypoint Mobility Model over two reactive routing protocols Dynamic Source Routing (DSR) and Adhoc On-Demand Distance Vec...
