introduction: estimation of cation exchange capacity (cec) with reliable soil properties can save time and cost. pedotransfer function (ptf) is a common method in estimating certain soil properties (e.g. cec) that has been wieldy used for many years. one of the common techniques that have been used to develop ptfs is multiple linear regressions. in this method, all easily obtained soil properti...

A sliding-mode controller (SMCr) synthesised using concepts of internal model control (IMC) is presented. An advantage of this method is a reduction of the inverse response effect by a feedback compensation element, proper of the IMC scheme. The performance and robustness of the proposed controller was tested and compared with a previous SMCr designed for inverse response systems (Camacho et al...

A comparison between linear stability analysis and observations of pulsation modes in five δ Scuti stars, belonging to the same cluster, is presented. The study is based on the work by Michel et al. (1999), in which such a comparison was performed for a representative set of model solutions obtained independently for each individual star considered. In this paper we revisit the work by Michel e...

introduction selection of the clear and transparent index for the precipitation using long-term homogeneous data is an important point for the researchers. several investigations have led to different indices for heavy rainfall. in some cases the specific amount of precipitation was used for heavy rainfall (rahimzadeh, 2005; masoodian, 2008; kamiguchi et al., 2006), e.g. alijani (2002) has sugg...

Automatic detection and tracking of moving object is very important task for humancomputer interface (Black & Jepson, 1998), video communication/expression (Menser & Brunig, 2000), and security and surveillance system application (Greiffenhagen et al., 2000) and so on. Various imaging techniques for detection, tracking and identification of the moving objects have been proposed by many research...

the aim of this study was to examine the relationship between coaching self-efficacy and iran premier league wrestlers' sport commitment. the research method was descriptive-correlation. the wrestlers from 8 teams (n=120) including all wrestlers in iran premier league (2012) completed demographic questionnaire, coaching self-efficacy scale (feltz et al., 1999), and sport commitment questio...

Cell signalling pathways make up the regulatory systems of mammalian cells. With the enormous progress in biochemistry and molecular biology of cellular processes over the past four decades and the emergence of new techniques in the last few years, an immense amount of data exists on cell signalling pathways and networks. Various groups (Bhalla and Iyengar 1999; Wiley et al 2003; Hautaniemi et ...
