the rank-k numerical range has a close connection to the construction of quantum error correction code for a noisy quantum channel. for noisy quantum channel, a quantum error correcting code of dimension k exists if and only if the associated joint rank-k numerical range is non-empty. in this paper the notion of joint rank-k numerical range is generalized and some statements of [2011, generaliz...

Dr. Victor R. Squires of Adelaide, Australia received the Outstanding Achievement Award for Stewardship at the Society for Range Management’s 68th Annual Meeting held in Sacramento, California earlier this month. The Outstanding Achievement Award is presented by the Society for Range Management for outstanding achievement to members and other qualified individuals and groups working with rangel...

Renewable natural resources are the wealth that not only belongs to the currentgeneration but also to future generations. Diversity in rangeland user viewpoints and policymakers has caused these lands to face some damages. This study was conducted to compareviewpoints of ordinary members as rangeland users, and board of directors as executives ofmanagement plans. Statistical population of the s...

In time-of-flight range imagers, as the range resolution increases, a gating clock skew becomes a serious problem. This paper describes two skew calibration techniques implemented in column-parallel circuits for TOF range imagers. Skew calibration technique with optical response is simple but the long calibration time is required. To reduce the calibration time, self-calibration technique with ...

rangelands are among the natural resources which have a considerable effect on environment and man’s life. iranian rangelands mostly have poor condition and exhausted by intensive over grazing, should be utilized according to their ecological capability and land suitability. the main objective of this study is to evaluate ecological capability and land suitability of gheshlagh dam’s watershed a...

Prof. Nosrat Safaeian from Sari, Australia received the Outstanding Achievement Award for Stewardship from the Iranian Society for Range Management at the 5th National Conference held in Boroujerd, Lorestan, Iran. He was born in Khorramabad and graduated in Ecology and Range Management from Montpellier, Science and Technique University, French in 1979.  I am honoured to introduce Prof. Nosrat S...
