in this paper, we use parametric form of fuzzy number and we converta fuzzy linear system to two linear system in crisp case. conditions for the existence of a minimal solution to $mtimes n$ fuzzy linear equation systems are derived and a numerical procedure for calculating the minimal solution is designed. numerical examples are presented to illustrate the proposed method.
in this paper a new algorithm is presented for coherent radar detection of targets, when distribution of the interference (clutter and noise) is non-gaussian. the neyman-pearson criterion is used for optimal detection and several successive received samples from a radar range cell are used for detection in the same cell. on the basis of recent empirical evidences, the interference distribution ...
Quantitative comparisons of distribution and abundance of exotic species in their native and non-native ranges represent a fi rst step when studying invaders. However, this approach is rarely applied particularly to tree species. Using biogeographical contrasts coupled with regional dispersal surveys, we assessed whether two exotic maple tree species, Acer negundo and Acer platanoides , can be ...
سطح برگ یکی از مهم ترین ویژگیهای گیاهان است که ارتباط مستقیم با متغیرهای اکولوژیکی و فیزیولوژیکی گیاه مانند شاخص سطح برگ، جذب نور، تبخیر و تعرق، فتوسنتز و رشد دارد، از اینرو محاسبه آن فوقالعاده حائز اهمیت است. در این پژوهش سعی شد با استفاده از یک روش غیرتخریبی (محاسبه مدلهای ساده رگرسیونی) و با اندازهگیری متغیرهای کمی برگ شامل طول و پهنا و ترکیب این دو متغیر، سطح برگ 7 گونه درختی شاخص قطعه ...
(∆− λ)f = T for a Γ-invariant distribution T on H, compactly-supported on Γ\H. The three main examples for T are described in detail below. That is, a slight roughness is tolerated in f at the support of the Γ-invariant distribution T . Three natural types of target distributions T are: (i) T is supported at a single point on Γ\H, (ii) T is supported on a closed geodesic on Γ\H, (iii) T evaluat...
In this study, two-year-old bare-root Acer negundo and pseudoplatanus seedlings were grown indoors (control vs. drought-stressed) outside the hoop house to examine leaf gas exchange parameters in late growing period. Besides morphological features, several parameters, such as net photosynthetic rate (Anet), transpiration (E), stomatal conductance (gs), intercellular CO2 ambient (Ci/Ca), water u...
