Urban green space (UGS) is crucial in providing ecosystem services and optimizing the health of urban residents. This study aimed at identifying suitable sites for UGS development using geospatial techniques Addis Ababa City. In present study, an analytical hierarchical process with Geographic Information Systems based multi-criteria evaluation was used development. Eight parameters namely land...

In this study, Iran crude oil samples (K, L) were separated on the basis of solubility and polarity, resulting in saturates, aromatics, resins, and asphaltenes fractions. The fractions were analyzed by traditional open column chromatography, thin layer chromatography-Flame ionization detector in an Itroscan instrument (TLC-FID) and Gas chromatography with flame ionization detection for the dete...

This paper extends the principal component analysis (PCA) to moderately non-stationary vector time series. We propose a method that searches for linear transformation of original series such transformed is segmented into uncorrelated subseries with lower dimensions. A columns’ rearrangement proposed regroup based on their relationships. discuss theoretical properties fixed and large dimensional...

Geomorphology affects the potential of land. The geomorphological condition an area has implications for physical characteristics, including: 1) type; 2) material; and 3) processes formed upon it. Understanding land capability allows evaluation suitability. Classification suitability is carried out by combining results identification with requirements plant growth or existing use. Evaluation ca...

Irrigation land suitability assessment and mapping play an imperative role for sustainable utilization of scarce physical land resources. The objectives of this study were to prepare spatial data base of physical land resources for irrigated agriculture and to assess land suitability for irrigation and developing suitable area map for the study area. The study was conducted at Fogera catchment,...

<p style='text-indent:20px;'>We consider the cooperative system driven by a multiplicative It\^o type white noise. The existence and their approximations of travelling wave solutions are proven. With moderately strong noise, constricted choosing suitable marker wavefront. Moreover, stochastic Feynman-Kac formula, sup-solution, sub-solution equilibrium points dynamical corresponding to uti...
