Total Quality Management is not just an admirable phenomenon but it is any client’s right and can be done through contribution of the staff and the managers as well as the client’s of an organization. The purpose of the present study is to investigate the feasibility of TQM model and the attitude of the managers of health field of Yazd medical sciences university towards it. The present study w...

In this paper we continue our study on adaptive genetic programming. We use Stepwise Adaptation of Weights (saw) to boost performance of a genetic programming algorithm on simple symbolic regression problems. We measure the performance of a standard gp and two variants of saw extensions on two different symbolic regression problems from literature. Also, we propose a model for randomly generati...

In order to study how acoustical factors influence annoyance responses to low frequency noise with tonal components, this research has selected 220 kV and 500 kV transformer noises as examples and an 11point numerical scale as an evaluation tool, in which the percentage of highly annoyed (%HA) and mean annoyance (MA) are chosen to represent annoyance caused by noises. Results show that a logist...

Hedonic pricing models attempt to model a relationship between object attributes and the object’s price. Traditional hedonic pricing models are often parametric models that suffer from misspecification. In this paper we create these models by means of boosted CART models. The method is explained in detail and applied to various datasets. Empirically, we find substantial reduction of errors on o...

Cui), mlw [email protected] (G. Zhang). Selecting good variables to build forecasting models is a major challenge for direct marketing given the increasing amount and variety of data. This study adopts the Bayesian variable sel...

The study was conducted to determine the constraints faced by the farmers in commercial cultivation of vegetables and to explore relationship between the selected characteristics of the farmers and constraints faced by them. Data were collected through personal interview from 142 randomly selected respondents out of 1422 vegetable growers of the three villages viz. Panchpara, Bagan and Rampur, ...

The Geographically Weighted Regression (GWR) is a method of spatial statistical analysis which allows the exploration of geographical differences in the linear effect of one or more predictor variables upon a response variable. The parameters of this linear regression model are locally determined for every point of the space by processing a sample of distance decay weighted neighboring observat...

Aims: Precise pistol shooting is influenced by arousal, which has been recently defined as an individual’s energetic state at a particular time and is measured by skin conductance level. On the other hand, task related activation has been defined as the change in arousal, from a resting baseline to the task situation. Present study was performed in order to investigate whether previous theories...

Statistical studies on the correlation analysis and multiple linear stepwise regression analyses based on the different geochemical fractions of metals (Cd, Cu, Pb and Zn) in the sediments of the Straits of Malacca were conducted. Significant (P< 0.001) correlation matrices were found among total concentrations of Cd, Cu, Pb and Zn indicating that they had a common source of anthropogenic origi...

Content-based prediction of musical emotions and moods has a large number of exciting applications in Music Information Retrieval. However, what should be predicted, and precisely how, remain a challenge in the field. We provide an empirical comparison of two common paradigms of emotion representation in music, opposing a multidimensional space to a set of basic emotions. New groundtruth data c...
