Background and Aim: To determine whether an inexpensive set up of point to point wireless intranet connection can provide adequate video and audio teleconferencing and image quality to support remote real-time surgical demonstration and telementoring. To our knowledge, there is no similar report from Iran. Materials and Methods: Surgeon performing a novel laparoscopic extraperitoneal trigonopl...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
We present an approach to the admission control and resource allocation problem in connection-oriented networks that offer multiple services to users. Users’ preferences are summarized by means of their utility functions, and each user is allowed to request more than one type of service. Multiple types of resources are allocated at each link along the path of a connection. We assume that the re...
even though, to date, a lot of studies have been conducted on the subject of politeness theory, there are very few studies regarding the applicability of this theory to translation between english and persian which shows the reason behind conducting the present study. this study was carried out with the aim of highlighting whether there is any difference between english and persian methods of u...
We1 propose a mechanism for providing long term quality of service in deflection networks. Our proposed protocol is in fact a call admission control (CAC) scheme based on session probing combined with a feedback technique that allows a station originating a new session to notify other stations about its bandwidth requirements. This CAC scheme works in an environment in which there are no explic...
1 Visiting Astronomer at the Infrared Telescope Facility which is operated by the University of Hawaii under contract to the National Aeronautics and Space Administration 2 ABSTRACT We present the discovery of CO fundamental ro-vibrational emission from the classical T Tauri spectroscopic binary DQ Tau. The high-resolution infrared echelle spectra reveal emission lines from both the v=1 and v=2...
Mobile computing environments increasingly consist of a range of supporting technologies offering a diverse set of capabilities to applications and end-systems. Such environments are characterised by sudden and dramatic changes in the quality-of-service (QoS) available to applications and users. Recent work has shown that distributed systems platforms can assist applications to take advantage o...
In today's era of communication where wireless media is replacing wired media, security is of utmost concern. The WiMAX technology was developed after the analysis of security failures in IEEE 802.11 technology. As WiMAX has a very high coverage area, security becomes one of the most important issues. Both mobile and fixed WiMAX has many striking features like connection-oriented MAC layer, pre...
Routing as well as the management of communication networks that support hybrid types of communications requiring quality of service is a hard problem. We present here a framework1 that decomposes the network into a hierarchy of abstract views of the network that summarizes the available bandwidth resources and highlights bottlenecks in the network in order to reduce the complexity of the previ...
