Device which eases classroom doors identification for visually impaired students
This present work is a device which eases classroom doors identification for students with visual impairments. It is composed of a MP3 module which sends audio messages about location and other information that helps the user, once the MP3 module is connected to an audio amplifier controlled by Arduino UNO. This project shows its importance when assistive equipment for visually impaired people, like tactile paving and braille staircase handrails, are not available inside buildings and facilities, because this work can guide and inform users about their localization without having to change buildings’ structures. At Instituto Federal do Paran´a - Campus Paranava´ı, the tactile paving only assists visually impaired students at the beginning of each facility, leaving them inside without any orientation. This present work aims to guide these students inside IFPR’s facilities and foster their independence. Nowadays, this project is at a prototype stage and required new components and modules, since it had some issues related to memory cards unavailability.
ANALYSIS OF THE IMPACT OF FLICKER ON POWER QUALITY WITH CODE VALIDATION IN MATLAB
Abstract—Voltage fluctuations and flicker are often grouped together; however, they are not equivalent. Voltage fluctuations
are rapid changes in the magnitude of the voltage whilst flicker is an ongoing modulation of the amplitude of the voltage waveform envelope. In a simple sense, voltage fluctuations may be thought of as the source and flicker the outcome; however, not all voltage fluctuations lead to problematic flicker. Thus, based on a programming made in MATLAB, a validation of the flicker effect in a low voltage network was obtained and demonstrates a 5.11% increase in nominal voltage when considering a flicker in the network.

Sound Monitoring Device
Abstract—This project is a electronic device that monitors the sound of the surrounding ambient, these sounds is capitated by a sound sensor named MAX 9814 which works as a microphone by detecting and converting the sound intensity into a electric signal, that then will be sent to the microcontroller Arduino Nano that is used to analyze and control the other components of the project. After the Arduino reads the electric signal sent by the sound sensor it will define if the sound intensity is too loud or not, if the sound intensity is loud enough or has an abrupt increase the SMD(Sound Monitoring Device) will enter in the alert mode. In these alert modes the SMD will activate the vibration motor that works as a tactile warning, this device will also activate a LED in the superior part of the device that will serve as a visual warning. The SMD also has a real time sound response called VU, which consists of a series of LEDs in a vertical bar in a manner that resembles a graphic meter. So depending on the sound intensity the LEDs will gradually turn on indicating the level of noise. This project aims to increase the security of people with hearing deficiency by alerting them of possible danger.
