abstarct development of greenhouse gases in future periods not only causes change in average amounts of climate variables but also makes variables of this variability affected. then for sure concerning alternations followed with climate variables’ fluctuations and its average amounts in effecting on runoff would make more reliable results. in this inquiry initially fluctuations and average amou...

We study the problem of k-visibility in the memoryconstrained model. In this model, the input resides in a randomly accessible read-only memory of O(n) words with O(log n) bits each. An algorithm can read and write O(s) additional words of workspace during its execution, and it writes its output to write-only memory. In a given polygon P , for a given point q ∈ P , we say a point p is inside th...
