An adaptive target queue length (ATQL) adjustment algorithm proposed in this paper cooperates with certain Active Queue Management (AQM) controllers to achieve more efficient buffer management for Internet congestion control. ATQL algorithm which estimates the average traffic load and dynamically adjusts the target queue length in dynamic traffic environment can be easily embedded into a series of AQM controllers. By engaging ATQL, AQM controllers are more suited to random and unpredictable traffic scenarios. Simulations are applied to validate ATQL's ability in assisting AQM controllers in sustaining stable drop probability, minimizing unnecessary packet loss, guaranteeing the link utility and maximizing the exploitation of buffer spaces.
Flow-level traffic measurement is important for network management. The widely used centralized per-flow measurement faces a great challenge due to the demanding requirement on both memory bandwidth and memory size wi...

This paper presents a Web-based control laboratory of a non-linear and unstable system: the ball and beam plant. Different control strategies, apart from the traditional PID, as Robust, Fuzzy and PD-Reset control have been taken to give students a wider vision of control approaches. The client-side of the virtual laboratory has been developed using EJS (Easy Java Simulations), an open-source tool that allows creating Java applications easily. Meanwhile, the application that locally interacts with the system is written in LabVIEW. Different experiences are presented showing the advantages of advanced control strategies over PD control.

The aim of this paper is to obtain a model for an in-scale fast-ferry model TF-120 including the dynamics and kinematics, using a remote experimentation platform for marine vehicles. The physical model is autonomous and is controlled remotely from a PC using Wi-Fi communications. The identification and validation of the dynamical model is obtained with turning circle maneuverings. In this model are included the kinematical equations. The tests with the autonomous in-scale physical model of the high-speed ship were carried out in the surroundings of the Bay of Santander. With this model. simulations with several turbojets angles are made.
