We revisit the interactive consistency problem introduced by Pease, Shostak and Lamport. We first show that their algorithm does not achieve interactive consistency if faults are transient, even if faults are non-malicious. We then present an algorithm that achieves interactive consistency in presence of nonmalicious, asymmetric and transient faults, but only under an additional guaranteed dela...

We employ an image identification algorithm for interactive museum guide with pictures taken by camera phones. Our algorithm is based on the shift-invariant feature transform (SIFT) algorithm. However, efficiency is a critical issue in the real-time interactive system, so a simplified version of SIFT algorithm is implemented in this work. Our testing database includes 33 paintings at the Cantor...

Collision detection and response are important for interactive graphics applications such as vehicle simulators and virtual reality. Unfortunately, previous collision-detection algorithms are too slow for interactive use. This paper presents a new algorithm for rigid or articulated objects that meets performance goals through a form of time-critical computing. The algorithm supports progressive...

This thesis proposes a new approach to video-based interactive narratives that uses real-time video compositing techniques to dynamically create video sequences representing the story events generated by planning algorithms. The proposed approach consists of filming the actors representing the characters of the story in front of a green screen, which allows the system to remove the green backgr...

Commonly, frequent patterns are mined by satisfying a user specified minimum support threshold or minsup in short. In some applications, finding proper frequent patterns by changing the value of minsup is needed. Since rerunning the mining algorithm from scratch can be very time consuming and may unacceptable for real time applications, researchers have introduced interactive mining. Although n...

Introduction. Influence as a heterogeneous phenomenon became the subject of interest in many sciences, since it is such that makes possible to correct behavior not only individuals, but also mass society .The weight research has especially increased conditions hybrid wars, which undoubtedly very relevant today’s conditions. Relevance study. The activation pathogenic, manipulative contexts leads...

The Internet has become a new medium, and educational activities have also undergone changes due to the development of technologies. In past, teaching that required students teach in specific time space changed less constraints, which made process pay more attention university mode under situation, makes comfortable intelligent. this paper, we propose an English interactive system based on asso...
