it is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. in this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. the non-uniform mesh is generated adaptively based on advancing front technique available in abaqus software. implementing severa...

the aim of this paper is to explain the relationship between generation gap and democracy in iran in the last fifty years. to do so, the writers have used the results of the national polls conducted in 1974, 1995 and 2002 in their attempt to clarify the activeness or inactiveness of the generation gap by analyzing the differences between the attitudes, values and behaviors of the young and adul...

This study focuses on the effect of social and cultural determinants on generation gap in Tehranian families in 2011. The purpose of this study is to determine effective factors on generation gap in Tehranian families, analytical and empirical patterns and be surveyed by related theories and effective factors. The research was prepared by questions including whether there is a relationship betw...

in this paper, second law analysis for calculations of the entropy generation due to the flow andheat transfer of water-al2o3 and ethylene glycol-al2o3 nanofluids inside annuli is presented. thephysical properties of the nanofluids are calculated using empirical correlations. constant heatfluxes at inner surface of the annuli are considered and fully developed condition for fluid flowand heat t...

Today, with the increase in the elderly population and life expectancy, the need to use care services for this significant part of the population is increasing. Beliefs, cultures, and social norms among different ethnicities and races are vital in the extent and nature of care. Two types of care exist, informal and formal. According to statistics by the Secretariat of the National Council on Ag...

a trend of significant increase in municipal solid waste generation has been recorded worldwide. this has been found due to over population growth rate, industrialization, urbanization and economic growth. consumerism speed has been found very high covering around more then 50% of total population since last decade due to higher economic growth, which has ultimately resulted in increased solid ...

The present study carefully examined entropy generation during wustite pellet reduction to sponge iron. The finite volume method was used to solve the governing equations. The grain model was used to simulate the reaction rate. The reactant gases including carbon monoxide and hydrogen were converted to water and carbon dioxide after wustite reduction. Entropy is generated by heat transfer, mass...

Wind Power generation integrated in electrical power system can cause of variation and uncertainty which must be considered in process of generation expansion planning (GEP). The goal of this study is to model the GEP problem integrated with wind power generation and introduce the fuzzy-probability model to consider variation and uncertainty of wind power generation. To verify and optimize the ...

average age distribution and generation interval were investigated in four different selection pathways. i.e., sire of future sires (ss), sire of future dams (sd), dam of future sires (ds) and dam of future dams (dd). young bulls pathway (yb) is also considered as a path that affects the generation interval in sd pathway when using progeny testing program. data were collected from animal breedi...
