A Simulated Fault Injection Tool for Dependable VoD Application Design
This work presents a simulation-based tool for dependability-oriented design of Video on Demand (VoD) applications. The tool is organized in a layered architecture, so that simulation models can be built and detailed according to a hierarchical and modular approach. The higher layer, namely the Application Level, provides a variety of objects to rapidly model fundamental components typically fo...
متن کاملA Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...

متن کاملThe study of Relationship between Mental Work Load and Sleep Quality in Video Display Terminals Users
Background & objectives: One of the factors affecting the performance of video display terminal users is their mental work load. Since low sleep quality causes fault and decreased accuracy in work, this study aimed to evaluate the relationship between mental work load and sleep quality in video display terminals users. Methods: This descriptive cross-sectional study was performed on 191 video d...
متن کاملDéveloppement d'applications logicielles sûres de fonctionnement : une approche dirigée par la conception. (Development of dependable applications: a design-driven approach)
development of dependable applications: a design-driven approach In many domains such as avionics, medecine or home automation, software applications play an increasingly important role that can even be critical for their environment. In order to trust these applications, their development is contrained by dependability requirements. Indeed, it is necessary to demonstrate that these high-level ...
