Monte Carlo simulation is an accurate way of assessing radiotherapy dose distribution in nonhomogeneous volumes, but it requires long processing times. A new distribution model simulates radiotherapy treatments and runs on a PC network, which reduces the processing time and makes for a powerful treatment-verification tool.
The SDR devices along with GNU Radio Software tool have taken the design of radio communications systems to a new level. This technology uses blocks-processing software that substitutes everything that is far implemented at the physical layer hardware. By designing a software radio system, this paper shows the implementation of a real time voice Tx and Rx(More)

This document proposes the design of a dynamic decision-making model in cognitive wireless networks that allows secondary users to opportunely harness the spectrum and use channels without affecting the traffic of primary users. The implemented model includes an initial decision-making algorithm with multiple criteria that classifies the best channels(More)
