because of urgent needs of groundwater resources in the tochal region of north tehran, an integration of electric and electromagnetic methods was applied to investigate the location and the direction of water bearing fractures. first, the vlf electromagnetic profiling was performed on suitable places and two locations were detected for supplementary resistivity surveys. then, a number of vertic...

In peer-to-peer networks, application relays have been commonly used to provide various networking services. The service performance often improves significantly if a relay is selected appropriately based on its network location. In this paper, we studied the location-aware relay discovery and selection problem for large-scale P2P streaming networks. In these large-scale and dynamic overlays, i...

Pain is a useful sensation. Nociceptive pain provides warning of impending or actual tissue damage and prompts aversive or attentive actions that protect the body from harm. People who do not feel pain, due to mutation of certain ion channels (1), suffer a lifetime of otherwise avoidable injuries. The consequences of losing the ability to feel pain also are highlighted by the symptoms and clini...

Thanks to Pylyshyn's work in the imagery debate, theorists are now apt to be at least a bit more cautious when they launch into descriptions of depictive representation. Even if the full force of his critique is not everywhere acknowledged, more care and vigilance is exercized when broaching talk of scanning mental images, focusing on such entities, or rotating them. The very places found in me...

Title of dissertation TIME-BASED LOCATION TECHNIQUES USING INEXPENSIVE, UNSYNCHRONIZED CLOCKS IN WIRELESS NETWORKS Matthew Yew Mun Mah, Doctor of Philosophy, 2011 Dissertation directed by Professor Ashok Agrawala Department of Computer Science The ability to measure location using time of flight in IEEE 802.11 networks is impeded by the standard clock resolution, imprecise synchronization of th...

Geolocation of Internet hosts relies mainly on exhaustive tabulation techniques. Those techniques consist in building a database, that keeps the mapping between IP blocks and a geographic location. Relying on a single location for a whole IP block requires using a coarse enough geographic resolution. As this geographic resolution is not made explicit in databases, we try in this paper to better...

the mean noise levels were measured in the different sections of six representative mills in the isfahan area, and audiometric measurements were made in 282 male workers employed in these mills. the mean noise levels were on average 95 dba in the weaving sections and 88 d ba in the spinning sections. the audiometric findings showed a significant loss of gearing in the textile workers as compare...
