background: indoor radon gas (222rn) has been recognized as one of the health hazards for human. air radon comes mainly from basement soil and construction materials. saghand region with rich uranium mines lies 180 km from yazd, so the indoor radon concentration can be high. yazd, with population of about 457000, is the biggest city near saghand, thus, indoor gamma background radiation of yazd ...

Active deformation in Alborz range is due to N-S convergence between Arabia and Eurasia. This paper provides geomorphic traces of regional deformation in NW Iran in order to characterize active faulting on major faults. Soltanieh and North Zanjan fault systems are involved in convergence boundary extent between South Caspian Basin and Central Iran. Soltanieh and North Zanjan faults are major re...

We describe a novel system for robotic measurement of contact sounds. This system is well suited for acquiring impulse-response sound models. A brief explanation of the sound models is included. We also describe experimental results to illustrate the process of acquiring sound models using our system, and a brief analysis of the results. The initial results are promising and could lead to appli...

Active measurements are integral to the operation and management of networks, and invaluable to supporting empirical network research. Unfortunately, it is often cost-prohibitive and logistically difficult to widely deploy measurement nodes, especially in the core. In this work, we consider the feasibility of tightly integrating measurement within the infrastructure by using Software Defined Ne...

Measuring QoS in the internet today is difficult as notions of what constitutes QoS vary. Service Level Agreements between customers and network service providers are often poorly defined. The most workable SLAs currently are defined in terms of how long packets may take to travel from some host to another host, and what acceptable levels of packet loss are. This paper presents a direct compari...
