Published: February 2021

A identificação da topologia de redes de energia elétrica é um problema para operação de sistemas elétricos, erros topológicos afetam aplicações como análise de contingencias, estimação do fluxo de potência, etc. Distinguir a forma de ligação das linhas em sistemas de distribuição torna-se ainda mais complexo, pois alterações são executadas frequentemente. A caracterização topologia pode ser considerado um problema de reconhecimento de padrões, dado que as tensões e fluxos de potência tem um vínculo direto com a estrutura em que as linhas de uma rede estão interconectadas, ou seja, alterações nessas conexões alteram a condição com que as correntes fluem pela rede. Com o progresso da capacidade de processamento dos computadores e a grande quantidade de informações disponíveis, a aprendizagem de máquina é bastante favorecida. O objetivo deste trabalho é aplicar técnicas de inteligência artificial para reconhecer a topologia de sistemas de distribuição a partir de informações de medições analógicas. Foram realizados testes, com base no sistema distribuição IEEE 33 barras, para recuperação das informações das linhas com ausência de parte de dados topológicos e dados das medições analógicas. A rede neural foi capaz de recuperar informações e retornar a topologia da rede de distribuição com êxito.

Published: February 2021

The traditional way to calculate fuel economy is done by using odometer reading and fuel consumed by car to travel that particular distance. This is a very narrow approach as fuel economy is affected by a variety of factors in the real world. Features such as throttle response, engine temperature, coolant temperature, gross weight of vehicle, etc. have a huge influence on the fuel economy. In order to overcome this problem, we have tried to predict fuel economy based on various features extracted from telemetric data in our project. In order to achieve this, we have implemented various feature selection and feature extraction techniques by further analyzing them with the purpose of calculating the effectiveness of those features to achieve high performance of machine learning algorithms that ultimately improves the predictive accuracy of the classifier. This provides us with the information regarding the amount of influence a particular feature has on the overall fuel economy of the vehicle.

Authors: Molla Saifuddin
Published: February 2021

Stress is a normal part of life. Everyone can feel stress from their environment, their own body and their own thought. It is a body’s reaction to any change that requires an adjustment or response. The body reacts to these changes with physical, mental and emotional responses. The human body is designed to experience stress and to it. Stress can be positive or negative. In positive side, it can keeping us alert, motivated and ready to avoid danger. Stress becomes negative when a person faces or embarrasses continuously without relief or relaxation from stress. As a result, the person becomes overworked and suffers from stressful arousal. In emergency stress situations, the body’s autonomic nervous system is activated to deal with stressful situations. However, this response remains active for a long time. This uninterrupted activity in response to stress causes the body to tear mentally and physically. Without relief, continuing stress can lead to a condition, called distress. Distress can disturb the body’s internal balance, resulting in significant physical, behavioural, emotional, social and intellectual responses in the individual stress becomes harmful when people engage in the compulsive use of substances or behaviours include food, alcohol, tobacco, drugs, gambling, sex, shopping, playing, video games and searching the internet to try to relieve their stress. But instead of returning to a relaxed state, these substances and compulsive behaviour keep the body in a stressful condition and cause more problems. There are all kind of situations that produce stress. These include good things, like new babies or new jobs and unpleasant things like divorces or illnesses.
