prediction of climatic variables on a local scale by general circulation models of the atmosphere is impossible because the models have large-scale network of resolution. therefore, downscaling methods are used to solve this problem. since the climate change phenomenon can affect different systems such as, water resources, agriculture, environment, industry and economy as well, selection of the...

Modernization as a process also affects the way a society thinks, its attitudes, beliefs, food, dress habits, and cultural patterns at the level of individuals, and as the individuals can be seen as units of the society. In this study, an attempt has been made to understand the consequences of modernization in the traditional housing pattern as reflected in the changes in Kitchen. For the prese...

background: tuberculosis (tb) is a pandemic disease. it is the second leading cause of death from infectious diseases after human immunodeficiency virus (hiv) in the world . the main objective of this paper was to determine and compare the epidemiology of tb incidence rate and its trend changes during 1990-2010 in six who regions regarding age, gender and income levels. methods: the average ann...

the major aim of processing satellite images is to prepare topical and effectivemaps. the selection of appropriate classification methods plays an important role. amongvarious methods existing for image classification, artificial neural network method is ofhigh accuracy. in present study, tm images of 1987, and etm+ images of 2000 and 2006were analyzed using artificial fuzzy artmap neural netwo...

because of low spatial resolution and simplifications in meteorological processes in global circulation models, they cannot sufficiently simulate the weather, comparing to the regional models; then, spatial and temporal downscaling of the gcm outputs are needed for decreasing errors of the global circulation models. there are two methods of downscaling: statistical and dynamic. weather generato...

We consider the frame problem, that is, char­ acterizing the assumption that properties tend to persist over time. We show that there are at least three distinct assumptions that can be made. We show the first assumption, which have been widely studied, is not naturally captured by circumscription. The first assumption is, "there is as little change as possible between one situation and the nex...
