This work investigates a novel approach called configurable beamforming on wireless physical layer security against passive eavesdroppers with Wireless Open-Access Research Platform (WARP). The aim is to create physical regions surrounding the intended user by configuring antenna array. By adapting the array configuration according to the intended user’s channel state information, it allows the...

More and more high definition and high quality videos are nowadays stored on Internet but they are not accessible for everybody because high and stable bandwidth is needed to stream them. A lower bitrate encoding is usually chosen but it leads to lower quality too. A solution is to use a TCP-friendly transport protocol and let the application itself choose for each user the bitrate of the video...

We present computational results of an implementation based on the fixed parameter tractability (FPT) approach for biplanarizing graphs. These results show that the implementation can efficiently minimum biplanarizing sets containing up to about 18 edges, thus making it comparable to previous integer linear programming approaches. We show how our implementation slightly improves the theoretical...

using image processing and artificial intelligence systems in agriculture and food industry is increasing daily. the purpose of this research is to study the feasibility of using image processing technique in predicting process of moisture content changes on green tea sheets during the drying using predictive artificial intelligence systems such as: artificial neural networks and adaptive neuro...
