2. METHODOLOGY AND DATA 2.1 Holdridge Life Zones In Holdridge (1967) life zones approach (Figure 1)‚ there two assumptions: 1) The temperature and precipitation variables are main factors determining life zones (or biomes). 2) The vegetation is assumed to be independent of animals. According to the assumptions‚ the primary influences on life zones are those factors that make up climate of the Holdridge system. In this respect‚ it is not unlike the systems of Köppen (1931) and Thornthwaite (1948)

Kriging is an optimal interpolator that has a minimum error variance.(Hung‚ 2001) Empirical Bayesian Kriging is a Kriging-based interpolation method that accounts for uncertainty in semivariogram estimation by simulating many semivariograms from the input data. In addition‚ Empirical Bayesian Kriging can account for moderate nonstationarity by building local models on subsets of the input data. Semi variance modeling was carried out to create the probability map. Empirical Kriging regression

interpolation methods (i.e. IDW‚ global polynomial interpolation‚ local polynomial interpolation‚ spline with 3 sub-types‚ and kriging with 4 sub-types) in Iraq. Based on the root mean square error values‚ the predicted values are compared with actual values for period between 1971 and 2010. The results demonstrated that the IDW yielded the best results‚ while the ordinary Kriging method occupied

A schematic diagram of DLR scramjet model [7-9] is described in Fig. 1.The air enters into combustion chamber at M=2.0 whereas hydrogen fuel (H2) is injected parallel to the air stream at M =1.0. The width and height of the combustor section at the entrance is 40 mm and 50 mm respectively which is then diverged at an angle of 3ο on the upper wall of the combustor. The strut is 32 mm long and 6mm height which are located at a distance of 77 mm from the entrance. The boundary conditions of Waidmann
