Mathematical modeling of an optimal control problem for combined chemotherapy and anti-angiogenic cancer treatment protocols [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
We formulate and analyze an optimal control problem for combined chemotherapy and anti-angiogenic therapy. The model couples tumor burden, vascular support, and a logistic surrogate for healthy tissue that encodes homeostasis and drug-induced depletion ...

QoE Optimization of Video Multicast with Heterogeneous Channels and Playback Requirements [PDF]

open access: yes, 2015
We propose an application-layer forward error correction (AL-FEC) code rate allocation scheme to maximize the quality of experience (QoE) of a video multicast. The allocation dynamically assigns multicast clients to the quality layers of a scalable video

Wind tunnel evaluation of YF-12 inlet response to internal airflow disturbances with and without control [PDF]

open access: yes, 1978
The response of terminal-shock position and static pressures in the subsonic duct of a YF-12 aircraft flight-hardware inlet to perturbations in simulated engine corrected airflow were obtained with and without inlet control.

Energy Optimal Transmission Scheduling in Wireless Sensor Networks

open access: yes, 2010
One of the main issues in the design of sensor networks is energy efficient communication of time-critical data. Energy wastage can be caused by failed packet transmission attempts at each node due to channel dynamics and interference.

A nonlinear plate control without linearization

open access: yesOpen Mathematics, 2017
In this paper, an optimal vibration control problem for a nonlinear plate is considered. In order to obtain the optimal control function, wellposedness and controllability of the nonlinear system is investigated.

mmWave Yagi-Uda Element and Array on Liquid Crystal Polymer for 5G

open access: yesIEEE Open Journal of Antennas and Propagation, 2023
Arrays on personal terminals are feasible using mmWave frequencies, but are limited by mutual coupling. A standard specification for MIMO is −15 dB coupling which can be readily attained over a modest bandwidth, and decoupling modifications can ...
