This paper attempts to rehabilitate student models within intelligent tutoring systems. Recently, some researchers have questioned both the need for detailed student models and the practical possibility of building them. We regard it as axiomatic that any intelligent tutoring system needs a student model. This paper suggests some practical guidelines and changes in philosophical approach which ...

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Measurement of solar radiance demands expensive devices to be used. Alternatively, estimator models are used instead. In this paper, a new method based on the empirical equations is introduced to estimate the monthly average daily global solar radiation on a horizontal surface. The proposed method uses Intelligent Water ...

The increasing amount and complexity of data used in predictive data mining call for new and flexible approaches based on hybrid intelligent methods to mine the data. This paper proposes a formal description for integrated data structures of Hybrid Intelligent Systems and the specification language HISML based on the open XML standard, introduced to fill the gap between simple soft computing mo...

during the past decade in iran, information technology (it) has had a deep impact on economy. many companies have invested on it and it’s complementary. despite a vast percentage of firm’s budget is spent on it continues increasingly, there are evidence which has been illustrate on failure of firms in obtaining the benefits of these expenditures within expected period. this fact nevertheless ha...

Intelligent Driver Model (IDM) is a well-known microscopic model of traffic flow within the traffic engineering societies. While it is a powerful technique for modeling traffic flows, the Intelligent Driver Model lacks the potential of accommodating the notion of drivers’ heterogeneous behavior whenever they are on roads. Concerning the above mentioned, this paper takes the lane to recognize th...
