Inter-cell interference has been traditionally handled by fixed partition based reuse schemes since the beginning of cellular era. Although effective for the then voice oriented networks, it is insufficient for modern day data communications as aggressive reuse is needed to support high data-rates. Due to its potential for spectrum efficiency, studies on dynamic inter-cell interference coordina...

Accelerated gradient methods are the cornerstones of large-scale, data-driven optimization problems that arise naturally in machine learning and other fields concerning data analysis. We introduce a gradient-based framework for achieving acceleration, based on recently introduced notion fixed-time stability dynamical systems. The method presents itself as generalization simple suitably scaled t...

This paper proposes an explicit rate-based end-to-end congestion control mechanism to alleviate congestion of multimedia traffic in packet switched networks such as the Internet. The congestion is controlled by adjusting the transmission rates of the sources in response to the feedback information from destination such as the buffer occupancy, packet arrival rate and service rate at the outgoin...

This paper investigates the dynamic selection of an appropriate threshold for basic Send-on-Delta (SoD) sampling strategies, given an available transmission rate to reduce the signal tracking-error. The paper formulates the error-reduction principle and proposes an algorithm that calculates, in real time, the amplitude threshold value (also called delta value) for a desired mean transmission ra...

This paper proposes a fair, rate-based end-to-end congestion control mechanism for multimedia traffic in packet switched networks such as the Internet. The scheme is modeled after a non-linear system. The congestion is controlled by adjusting the transmission rates of the sources in response to the feedback information from destination such as the buffer occupancy, packet arrival rate and servi...

This paper studies the interest of the integration of battery energy storage with Static Synchronous Compensator (STATCOM) for improving the low voltage ride through capability (LVRT) of a fixed speed wind turbine connected to the grid. For this reason and by applying a grid fault, a comparison is made between integrating the SSSC, the STATCOM and the STATCOM with battery energy storage. The sy...

We propose a general strategy for designing coupling functions in order to achieve a desired amplitude dynamics in coupled nonlinear oscillators. The target dynamics achieved by the proposed control schemes is a fixed-point motion at a desired amplitude level or a periodic motion at a desired frequency. The control schemes are illustrated with Rössler and Hindmarsh-Rose oscillators.

To achieve a desired fixed or variable speed (feedrate) along a given curved path, CNC machines employ independent motors to drive each of their axes in a time-coordinated manner. There are physical limits to the torque and power that the motors can supply, and the machine performance is compromised if the demands of overcoming machine inertia, cutting forces, and friction exceed these limits. ...
