in this research work, the impact of user’s behavior on search engine results is discussed. it aims to improvement of search results which leads to the higher satisfaction of users. in other words, we are trying to present a personalized search engine for each user, based on his/her activity and search history. we base our hypothesis that the search history of each user in a specific time frame...

the control of car following is essential due to its safety and its operational efficiency. for this purpose, this paper builds a model of car following behavior based on armax structure from a real traffic dataset and design a model predictive control (mpc) system. based on the relative distance and relative acceleration of each instant, the mpc predicts the future behavior of the leader vehic...

Web search engines answer user needs on a query-by-query fashion, namely they retrieve the set of the most relevant results to each issued query, independently. However, users often submit queries to perform multiple, related tasks. In this paper, we first discuss a methodology to discover from query logs the latent tasks performed by users. Furthermore, we introduce the Task Relation Graph (TR...

Usage of mobile wireless Internet has grown very fast in recent years. This radical change in availability of Internet has led to communication of big amount of data over mobile networks and consequently new challenges and opportunities for modeling of mobile Internet characteristics. While the traditional approach toward network modeling suggests finding a generic traffic model for the whole n...

Interactive virtual characters are expected to lead to an intuitive interaction via multiple communicative modalities such as the expression of emotions. Generating facial expressions that are consistent with the interaction context is a challenge. This paper presents our interactive facial animation system based on the Component Process Model, generating facial signs of appraisal during a real...

Ad hoc network users are resource constrained: Before transmitting data, they have to take into account the energy expenditure involved. Even if a user is, in principle, willing to spend energy to improve network connectivity, his actual decision will be heavily influenced by the decisions of his neighboring users, since they act as relay nodes for him. Moreover, some of the neighbors may not b...

Database modeling is based on the assumption of a high regularity of its application areas, an assumption which applies to both the structure of data and the behavior of users. Content modeling, however, is less strict since it may treat one application entity substantially differently from another depending on the instance at hand, and content users may individually add descriptive or interpre...

today hydrogels are considered as the materials that are able to play important role in drug delivery systems. to design an effective hydrogel applicable network, mathematical modeling has a critical role. a successful drug delivery device relies not only on intelligent network design but also on accurate prior mathematical modeling of drug release profiles. in this study, the modeling of the i...

Modeling languages are used by software engineers to design and document the structure and behavior of a system. Although many modeling languages have been proposed, Domain-Specific Modeling Languages (DSMLs) have emerged recently due to their simplicity and expressiveness for a particular domain. However, it is not easy for end-users to design and implement DSMLs because DSML development requi...

An exploration with two main goals is presented: 1. Modeling a self-contained "intelligent building," the Mars Arctic Research Station (MARS) habitation unit, and interaction with its users. The modeling effort seeks representation of invisible aspects of the interactions between the station and its users rather than visible forms. 2. Examination of how (or if) the modeling process contributes ...
