However, designing a well organized control mechanism in terms of time– cost point of views had not been taken into considerations. In this paper, such a control mechanism is implemented successfully using earned value analysis which is well-k...

This paper deals with rough set approach on lattice theory. We represent the lattices for rough sets determined by an equivalence relation. Without any loss of generality, we have defined the rough set as a pair of sets (lower approximation set, upper approximation set) and then we showed that the collection of all rough sets of an approximations by an equivalence relation form a lattice by som...

This paper deals with the problem of testing hypothesis when both the hypotheses and the available data are fuzzy. First, four different kinds of fuzzy hypotheses are defined. Then, a procedure is developed for constructing the fuzzy point estimation based on fuzzy data. Also, the concept of fuzzy test statistic is defined based on the α-cuts of the fuzzy null hypothesis and the α-cuts of the c...

function of the pre-fire vegetation and the post-fire environment. Much of the area burned is characterized by total tree death, and the young post-fire vegetation is dominated by fast growing successional species, which are eventually succeeded by longer-lived tree species. Direct fire combustion releases in Canada are about 1.5 kg C m on average, plus some additional greenhouse gases such as ...
