There are many models used in global solar radiation prediction. However, these prediction vary according to the climate and geographic characteristics of region involved. When model determined for a is different region, may not work. In order gain absolute stable results from models, studies should be either custom-made or tested. this study, 7 were examined, comparison charts created statisti...

Con la finalidad de generar información útil para el sector productivo cafetalero, como parte las actividades del Observatorio Cafeticultora Veracruz (OBSERVA-CAFE), se realiza estimación distintos índices que permitan conocer condiciones ambientales en desarrolla cultivo café y ayuden a los productores toma decisiones cuanto prácticas manejo implementadas sus sistemas producción. este sentido,...

In this context, a novel structure has been proposed for simple Differential Evolutionary (DE) algorithm to solve optimal recloser placement. For this, an operator is added to DE algorithm to adapt concept of the problem. Other contribution of this work is formulating a novel objective function. The proposed objective function has been formulated to improve four reliability indices which consis...

The assessment of aridity conditions is a key factor for water management and the implementation mitigation adaptation policies in agroforestry systems. Towards this aim, three indices were computed Iberian Peninsula (IP): De Martonne Index (DMI), Pinna Combinative (PCI), Erinç Aridity (EAI). These first baseline period 1961–1990, using gridded observational data (E-OBS), subsequently, periods ...

    In this research in order to frequency analysis of maximum daily rainfall in various climates of Iran the data of 40 synoptic rain gauges collected in 40 years period i.e., 1973 to 2012 were used. These stations are located in various climates of Iran according to De Martonne climatic classification. At first, input of data to HYFA package was performed. The mentioned package includes seven...

‎Let G=(V(G),E(G)) be a simple connected graph with vertex set V(G) and edge‎ ‎set E(G)‎. ‎The (first) edge-hyper Wiener index of the graph G is defined as‎: ‎$$WW_{e}(G)=sum_{{f,g}subseteq E(G)}(d_{e}(f,g|G)+d_{e}^{2}(f,g|G))=frac{1}{2}sum_{fin E(G)}(d_{e}(f|G)+d^{2}_{e}(f|G)),$$‎ ‎where de(f,g|G) denotes the distance between the edges f=xy and g=uv in E(G) and de(f|G)=∑g€(G)de(f,g|G). ‎In thi...

Recently in agricultural and industrial sectors, researchers have started to classify the climate of a region using empirical methods clustering. This study aims compare four approaches classification (Thornthwaite Mather, De Martonne, Extended IRIMO (I.R. Iran Meteorological Organization)) with Ward’s hierarchical agglomerative clustering applied Iran. The dataset used this comprises maximum m...

Urbanization and climate change are two inevitable megatrends of this century. Knowledge about the growth responses urban trees to is utmost importance towards future management green infrastructure with aim a sustainable provision environmental ecosystem services. Using tree-ring records, study analyzed response by stem diameter at breast height (DBH) 1178 in seven large cities worldwide, incl...
