Finding answers to why-questions involves finding arguments in texts, rather than the noun phrases that are typical targets for factoid questions. Detecting arguments requires detecting specific rhetorical structures and relations. Therefore, we proposed the use of Rhetorical Structure Theory (RST) as a tool for discovering answer to why-questions in paragraphs that are likely to contain the an...

As a product of the in-depth integration information technology and classroom teaching, smart is carrier intelligent interactive mode, which can realize structure reform precise teaching. Intelligent mode new way choice college teaching at present. The exploration application interaction in three aspects English courses show that has promoting effect on intelligence development personality.

Protein secondary structure prediction is one of major challenges in bioinformatics, data ming. In this paper, we propose a novel intelligent prediction system model-Compound Pyramid System Model, which may become the classic model for predicting protein secondary structure. It consists of four components by intelligent interfaces and synthesizing several methods such as SAC (Structural associa...

in order to reduce the volume and size of distribution power transformer, precise and extended controlling of transformer output, the conventional transformers are replaced by intelligent universal transformers (iuts). in this paper, an iut, typical of iran national grid, with the voltage ratio of 20kv:380 v is designed and simulated. regarding the iut implementation, a cascaded h-bridge invert...

nowadays, because of the growing numbers of vehicles on streets and roads, the use of intelligent controlsystems to improve driving safety and health has become a necessity. to design and implement suchcontrol systems, having information about traffic light colors is essential. there are the wide variety oftraffic lights in terms of light intensity and color. therefore it seems that design and ...

A novel control structure model is proposed based on cloud model for the first time.The structure model is a nonlinear model in nature, and it can be composed of a group of uncertain reasoning rules easily. NonIinear mapping characteristics of cloud model is analysed in this sudy, and the design method of the intelligent controller is presented based on the structure model, and some simulation ...

Intelligent tower crane has large structure deadweight. The service life of the whole machine is dependent on the life of the structure. As a result, the metal structure should be designed by using correct and reasonable methods to obtain excellent fatigue properties. And it can guide the design, manufacturing, use and maintenance process for crane. And it has great significance to prevent the ...

Knowledge space theory provides a formal model for representing students' knowledge and describing the structure of a domain of knowledge. A similar formal structure can be used to described the structure of hypertexts. The combination of knowledge space theory and the formal hypertext model leads to a framework for intelligent tutoring systems which provides individualized learning paths to a ...

in this paper, an observer based fuzzy adaptive controller (fac) is designed fora class of large scale systems with non-canonical non-affine nonlinear subsystems. it isassumed that functions of the subsystems and the interactions among subsystems areunknown. by constructing a new class of state observer for each follower, the proposedconsensus control method solves the problem of unmeasured sta...

There has been a long-standing interest in how to estimate the prerequisite structure among a set of skills. This prerequisite structure is important for intelligent tutoring systems and the educational data mining community, because it has important implications for student modeling, and for automatically constructing teaching policies. Here we present preliminary work towards inferring skill ...
