Algorithms, artificial intelligence and NLG in the production of Brazilian journalism
This work evaluates the scenario and the possibilities of using technologies such as algorithms, artificial intelligence and NLG language in Brazilian media companies. Exploratory and descriptive research was carried out, as well as participant observation and documentary data analysis of 10 organizations. Among the results achieved, there is disbelief and skepticism with the algorithms, together with the scarce possibility of adopting this technology in the short and medium term for news production

Optimization of the propagation model choice by measuring field and artificial intelligence
The propagation model to be chosen in the design of a terrestrial television station is a critical point for predicting the coverage area. This paper presents a study of the choice of propagation model, through the use of artificial intelligence (AI). Using the propagation model criterion that presents the smallest error between the field measurement and the software simulation, an IA method of classification learning was developed.

Design of Stepped Impedance Microstrip Low-Pass Filter for Coexistence of TV Broadcasting and LTE Mobile System Close to 700 MHz
The evolution of mobile networks has demanded more frequency spectrum and in many countries part of UHF band previously allocated to TV broadcasting now is used to broadband mobile networks and is important avoid any interference caused by signals transmitted in adjacent bands. In the Brazil and in others countries the new spectrum is being assigned to Long Term Evolution (LTE) mobile networks at 700 MHz band that is close to the frequency spectrum used by TV broadcasting. In this context the paper presents a microstrip low-pass filter to be used into television and avoid interferences produced by LTE signals. The proposed low-pass filter was designed using microstrip step-impedance method, fifth-order Chebyshev with ripple of 0.01 dB and cut-off frequency at 700 MHz. The designed low-pass filter was simulated using full wave simulator Ansoft HFSS. After simulation the low-pass filter was fabricated by photolithographic process in a FR-4 pcb. Finally, it was tested using vector network analyzer and the measured results presented a good agreement with the simulations.

Improvement of the Content Transmission in Broadcasting Systems: Potential Proposal to Rayleigh and Rician Multichannel
A model based on discrete events was developed and applied to a broadcasting system, using the Simulink simulation environment of the MATLAB software. With the objective of improve the transmission of content, through a pre-coding process of bits applying discrete events in the signal before of the modulation process, with the implementation of discrete entities in the process of bit generation. The results show better computational performance related to time and memory utilization, related to the compression of the information.

Proposal of A Medical Algorithm Based on the Application of Digital Image Processing and Visual
The erythrocytes counting and leukocytes help detect various types of diseases. Given the wide applicability of the Watershed Transform (WT) and Morphological Operations (MO), was developed the WT-MO algorithm for segmentation, detection, and counting of blood cells. The WT-MO algorithm results in high accuracy (93%). Therefore, the algorithm is accurate, reliable and a low-cost technique, which can be applied as a third methodology to perform the laboratory tests and to speed up further medical diagnostic.
