The geographic distribution of Astragalus (Fabaceae) in Iran was analyzed using a database of 7606 georeferencedobservations. Astragalus occurs in all provinces of Iran, but 88% ofthe observations are in five provinces including Tehran, West-Azerbaijan, Esfahan, Kordestan, and Khorasan-e Razavi.Most species are rare and narrowly endemic: Thelargest distance between two observations of the same ...

Data distribusi diformulasikan dengan transportasi, sehiggga diperoleh keseimbangan penambahan variabel dummy tabel air, solusi awal fisibel perhitungan Corner. Berdasarkan optimum Di...

Consider an r × (n − r) plane lattice rectangle, and walks that begin at the origin (south-west corner), proceed with unit steps in either of the directions east or north, and terminate at the north-east corner of the rectangle. For each integer k we ask for N k , the number of ordered pairs of these walks that intersect in exactly k points. The number of points in the intersection of two such ...

Transport problems is very important in operational research. The transport problem has been solved several ways: north west corner, minimum cell cost and Vogel’s approximation method. In this study, I discussed a new method to find an optimal solution of transportation simple step. All methods were applied paper evaluate the results compare between them with respect Also, researcher example on...

Let Q be the Q-matrixof an irreducible, positive recurrent Markov process on a countable state space. We show that, under a number of conditions, the stationary distributions of the n × n north-west corner augmentations of Q converge in total variation to the stationary distribution of the process. Twoconditions guaranteeing such convergence include exponential ergodicity and stochastic monoton...

A mathematical model for studying the 3-D dynamical structure of lee wave across a meso-scale mountain corner has been proposed mean flow with realistic vertical variation wind and temperature. The basic consists both zonal component (U) meridional (V), which are assumed to be dependent height. Brunt-Vaisala frequency (N) is also This applied corner, in North East India, formed by broadly North...
