The new formalism for description of (un)polarized semi-inclusive DIS at moderate energies is developed. Hadron production is modeled as a product of distribution functions and hadronization functions (HFs) weighted by the hard scattering cross sections, as it is done in the LEPTO event generator. The correct treatment of polarization effects shows that description of semi-inclusive DIS within ...

The goal of this thesis project is to build an effective multiclass classifier which can be trained with a small amount of labeled data and a large pool of unlabeled data by applying semi-supervised learning in a boosting framework. Boosting refers to a general method of producing a very accurate classifier by combining rough and moderately inaccurate classifiers. It has attracted a significant...

the solar radiation received by earth surface is one of the most applicable parameter that is so important in hydrology, agriculture, meteorology and climatological modeling. because of very expensive instrument for measuring the radiation, researchers suggested many different experimental equations to estimate this parameter in different climate. seven models which are calibrated for semi-arid...

soil conservation and control of erosion is a basic problem in all countries. the goal of this research is to estimate erosion and sediment yield in ekbatan dam drainage basin by erosion potential method (epm), using geographic information system (gis). the basin is located in hamedan province, west of iran, in a cold and semi- arid region, with an average annual rainfall of 334mm. the study ar...

in more recent years, it has become increasingly recognized that r&d; (research and development) is a key driver of economic growth, a source of innovation and change, and as such stimulates improvements in productivity and economic competitiveness. it is closely associated with knowledge and flexibility, two factors that have gained new significance as a source of competitiveness in an increas...

conclusions the study findings suggest that mothers' knowledge and practice in the use of antibiotics is moderate, and lower parental education may lead to unnecessary antibiotic consumption and resistance. objectives the objective of this study was to study the knowledge and behavior of mothers about antibiotic use in children under six years old with urti. methods ninty-seven mothers with chi...

The purpose of this paper is to introduce the concepts of semi*-connected spaces, semi*-compact spaces and semi*-Lindelof spaces. We investigate their basic properties. We also discuss their relationship with already existing concepts. Mathematics Subject Classification: 54D05, 54D30.
