in order to identify and selection salt tolerant hybrids based on tolerance indices, 17 sugar beet three-way cross hybrids produced by crosses between 17 salinity improved s1 pollinators and a cytoplasmic male sterile (cms) single cross as female, along with three control genotypes were grown in 2007 in rudasht station (isfahan) under saline (12 ds/m and 8 ds/m for water and soil) and non-salin...

The paper discusses a number of issues concerning the practical usefulness of cognitive psychology research, and presents a ease study ofpilot training methods to illtistrate a model of research processes that produce; outcomes which contribute to both basic and applied 'research goars. ResearCh studies are described as varying in the -degree to which they include reviews of the literature, pre...

A popular myth is that, for NP -hard problems, there are no algorithms with worst-case running time better than that of brute-force search. Reality is more nuanced, and for many natural NP -hard problems, there are algorithms with (worst-case) running time much better than the naive brute-force algorithm (albeit still exponential). This lecture proves this point by revisiting three problems stu...

Last lecture, we discussed Janus, which uses system call interposition to achieve software sandboxing isolation. We talked about a few problems that Janus had, particularly race conditions that can potentially allow malicious code to break software isolation property. Since then, a few more sandboxing projects have been implemented to address such issues. Today, we are going to look at a few re...

Abstract The main objective of ISO/TC 261 is to standardise the processes additive manufacturing, process chains (Data, Materials, Processes, Hard- and Software, Applications), test procedures, quality parameters, supply agreements, environment, health safety, fundamentals vocabularies.
