A mural excavated at the Neolithic Çatalhöyük site (Central Anatolia, Turkey) has been interpreted as the oldest known map. Dating to ∼6600 BCE, it putatively depicts an explosive summit eruption of the Hasan Dağı twin-peaks volcano located ∼130 km northeast of Çatalhöyük, and a birds-eye view of a town plan in the foreground. This interpretation, however, has remained controversial not least b...

equal channel angular rolling (ecar) is a severe plastic deformation method that covered plasticdeformation of sheets. in this study, effects of ecar route shave been investigated on themechanical and microstructure properties of explosive-welded al-cu bimetal. at first, the explosivewelding process has been performed to prepare the al-cu bimetals. then, to relieve the stress andpreparing of sa...

Norway is a country with large geographical dimensions and a very low number of inhabitants. This combination makes advanced telecommunication services and distributed multimedia applications, like telemedicine and distance education, very important for the Norwegian society. Obviously, an appropriate networking infrastructure is necessary to enable such services and applications. In order to c...

Heterogeneous disk arrays are becoming a common configuration in many sites and specially in storage area networks (SAN). As new disks have different characteristics than old ones, adding new disks or replacing old ones ends up in a heterogeneous disk array. Current solutions to this kind of arrays do not take advantage of the improved characteristics of the new disks. In this paper, we present...

It is always the hotspot of society attention and academy study how to improve the efficiency of large-scale instruments and equipment (LSIE). Constructing a Data Collection System based on Wireless Local Area Network (WLAN) is an important method of lab performance management and then promoting the LSIE integration efficiency. Focus on the WLAN environment LSIE working state information collec...

INTRODUCTION This study aims at investigating the implementation process of electronic network systems in Japanese large firms, focusing on the innovativeness among industries to which firms belong. The electronic network systems such as Local Area Network (LAN) have spread rapidly during last several years. Accordingly, many firms in Japan have introduced them in their organizations. After the...

A wireless body area network (WBAN) consists of a wireless network with devices placed close to, attached on, or implanted into the human body. Wireless communication within a human body experiences loss in the form of attenuation and absorption. A path loss model is necessary to account for these losses. In this article, path loss is studied in the heterogeneous anatomical model of a 6-year ma...

this work is focused on synthesis of sio2- cnt hybrides via sol-gel method. homogeneous distribution of carbon nanotubes within silicon matrix was obtained by mixing the functionalized carbon nanotube (cntcooh) with active silicic acid followed by titration to the solution of sodium silicate (na2sio3) under the average temperature condition of 80?c. different ratios of multi-walled carbon nanot...

Trends in conventional storage infrastructure motivate the development of foundational technologies for building a wide-area read-write storage repository capable of providing a single image of a distributed storage resource. The overarching design goals of such an infrastructure include client performance, global resource utilization, system scalability (providing a single logical view of larg...
