Distributed multicast tree generation with dynamic group membership

Frank Adelstein, Golden G Richard, Loren Schwiebert
2003 Computer Communications  
To remedy this, we propose an efficient distributed algorithm that supports dynamic changes to the multicast group during tree building and allows concurrent join/leave operations.  ...  Many such algorithms, both centralized and distributed, have been proposed to generate 'good' multicast trees.  ...  Acknowledgements The authors are very grateful to Christine Richard for editorial assistance.  ...

Scheduling Interactions in Learning Videos: A State Machine Based Algorithm

Josef Wachtler, Martin Ebner
2019 International Journal of Learning Analytics and Artificial Intelligence for Education (iJAI)  
Finally, the evaluation of the algorithm points out that it is generally working after the improvement of some drawbacks regarding the distribution of interactions in the video.  ...  The algorithm is implemented by a web application and it is based on the concept of a state machine.  ...  Strictly this is not part of the algorithm but it is required for better understanding. When a student joins a video the algorithm starts with the interaction planner.  ...

Modular and flexible causality control on the Web

Paul Leger, Éric Tanter, Rémi Douence
2013 Science of Computer Programming  
Ajax allows JavaScript programmers to create interactive, collaborative, and user-centered Web applications, known as Web 2.0 Applications.  ...  In this paper, we study how causality issues affect these applications and present WeCa, a practical library that allows for modular and flexible control over these causality issues in Web applications  ...  Finally, we ran benchmarks in order to test how practical is WeCa for the real Web applications. Many WebApps are highly interactive in nature and are not performance-sensitive.  ...

A framework for specifying and verifying the behaviour of open systems

Andrea Bracciali, Antonio Brogi, Franco Turini
2005 The Journal of Logic and Algebraic Programming  
Moreover, the recent advent of a network-centric model for software applications poses further problems to the development process.  ...  We define a notion of partial correctness, acceptability, in order to deal with the intrinsic indeterminacy of open systems, and we provide an algorithmic procedure for its effective verification.  ...  Acknowledgements We would like to thank the anonymous referees for their valuable suggestions that have contributed to improve the paper.  ...

Holistic Query Transformations for Dynamic Web Applications

Amit Manjhi, Charles Garrod, Bruce M. Maggs, Todd C. Mowry, Anthony Tomasic
2009 Proceedings / International Conference on Data Engineering  
We then present algorithms for automating these transformations in a source-to-source compiler.  ...  This approach, unfortunately, can introduce latency between the application and database servers, which in turn increases the network latency of Web interactions for the clients (end users).  ...  For the ViewStory interaction of the bboard application, while the latency reduction for low-latency interactions 1 was 78%, the latency reduction for the high-latency interactions was only 58%.  ...
