The rapid growing of information technology (IT) motivates and makes competitive advantages in health care industry. Nowadays, many hospitals try to build a successful customer relationship management (CRM) to recognize target and potential patients, increase patient loyalty and satisfaction and finally maximize their profitability. Many hospitals have large data warehouses containing customer ...

flow unit characterization plays an important role in heterogeneity analysis and reservoir simulation studies. usually, a correct description of the lateral variations of reservoir is associated with uncertainties. from this point of view, the well data alone does not cover reservoir properties. because of large well distances, it is difficult to build the model of a heterogenic reservoir, but ...

The theory rough set successfully implemented diberbagai sector , but rough set model classical can only associated with the data complete and set of data in symbolic form ( Jianhua , dai , 2013 ) . Research by adopting the theory rough set conducted in attribute numerical and the value of an attribute lost ( Jerzy w , Grzymala-Buse and Zdzislaw S , Hippe , Nov .2011 ) .In this research discuss...

The recreational site choice decision modeled in most economic analyses seldom contains previous experience with the site as a characteristic or attribute. A rational dynamic model is used to incorporate previous experience with the site in a model of the choice of recreation sites. Based on the comparison of dynamic and static models, it is apparent that dynamic elements influence choice. The ...

The eld of object-oriented databases is su ering from the lack of a|widely agreed upon|formal model. In this paper we develop the basics of a formal model for an object-oriented data model (kernel). The formalization is based on dynamic logic: combining many-sorted algebras with states and state transitions. The many-sorted algebras are utilized to model the static aspects, i.e., the value-orie...
