We present the first southern-hemisphere all-sky imager and radio-transient monitoring system implemented on two prototype stations of low-frequency component Square Kilometre Array. Since its deployment has been used for real-time recorded commissioning data. Additionally, a transient searching algorithm executed resulting images. It uses difference imaging technique, enabled identification wi...

In this paper trends of precipitation and stream flow are analyzed in the Atrak River basin in the North Khorasan province. Normal score linear regression, Mann-Kendall, and Seasonal Kendall trend tests were adopted. Three precipitation variables and two stream flow variables including total precipitation, maximum daily precipitation, and number of rainy days, mean discharge and peak discharge ...

The Modelica specification is ambiguous as to whether all the events are synchronous are not. Different interpretations are possible leading to considerable differences in the ways models should be constructed and compilers developed. In this paper we examine this issue and show that there exists an interpretation that is more appropriate than others leading to more efficient compilers. It turn...

A protocol for the reliable multicast of data to mobile hosts is described. A logical ring is maintained between all the base stations that handle the multicast traffic of the same multicast group. A token passing protocol enforces a consistent view between all base stations with respect to the frames that are considered delivered to all mobiles. The interaction of the reliable multicasting and...
