mobile ad-hoc networks have attracted a great deal of attentions over the past few years. considering their applications, the security issue has a great significance in them. security scheme utilization that includes prevention and detection has the worth of consideration. in this paper, a method is presented that includes a multi-level security scheme to identify intrusion by sensors and authe...

Modern Grid systems use web services to interact with remote and distributed subsystem components to achieve an effective and common connection. Next generation Grid solutions will include instruments and sensors as part of the Grid, in addition to computational units (CE) and disk storage (SE). The Instrument Element (IE) is a new component that provides access to these remotely distributed pi...

objective: vertical root fracture (vrf) is among the most common causes of endodontic treatment failures. this study aims to compare charge-coupled devices (ccd) and photostimulable phosphor plates (psp) for detection of vertical root fractures in endodontically treated teeth.   methods: in this diagnostic in vitro study, 40 maxillary anterior teeth were selected and after preparation and root ...

adulteration in milk and other dairy products not only is a serious threat to human health but also leads to the economic losses in the dairy industry. utilization of the materials reducing microbial load is a common adulteration. in this study, a machine olfaction (electronic nose) based on 8 metal oxide semiconductor (mos) sensors was fabricated and developed and its capability to formalin de...
