Application of a Frequency Converter in Electric Automatic Control of Central Heating by Jingwen Yin, Guifeng Zhang

“…The experimental results show that the temperature control strategy using a frequency converter automatic compensation method reduces the energy waste caused by manual regulation to a certain extent. When the speed of a water pump motor decreases to 4/5 of the original, the power consumption will decrease to about 52% of the original and save about 48% of the power; When the speed drops by 3/5, the power consumption is about 22% of the original, saving about 78% of the power. …”

Cluster of factors associated with physical frailty in community-dwelling elderly people by Saulo Vasconcelos Rocha, Manuela Alves dos Santos, Iasmim de Santana Meira Santos, Clarice Alves dos Santos, Mariana Alves dos Santos, Maria Luiza Oliveira Silva, Guilherme Eustáquio Furtado, Hector Luiz Rodrigues Munaro

“…As for sociodemographic variables, those who were older and had lower levels of education were more likely to have three or more risk factors. The development of actions that encourage a healthier lifestyle to favor the prevention and treatment of physical frailty, as well as to increase health literacy and knowledge, may reduce the problems related to this condition in older adults, mainly thinking about the next generations. …”

Gaze–Hand Steering for Travel and Multitasking in Virtual Environments by Mona Zavichi, André Santos, Catarina Moreira, Anderson Maciel, Joaquim Jorge

“…We present a gaze–hand steering technique that combines eye tracking with hand pointing: users steer only when gaze aligns with a hand-defined target, reducing unintended actions and enabling free look. Speed is controlled via either a joystick or a waist-level speed circle. …”

Federated deep reinforcement learning-based urban traffic signal optimal control by Mi Li, Xiaolong Pan, Chuhui Liu, Zirui Li

“…The proposed method improves the model generalization ability of different local models during global cross-region distributed joint training under the premise of ensuring information security and data privacy, solves the problem of non-independent and homogeneous distribution of environmental data faced by different agents in real intersection scenarios, and significantly accelerates the convergence speed of the model training phase. By reasonably designing the state, action and reward functions and determining the optimal values of several key parameters in the federated collaboration mechanism, the RL model could ensure high learning efficiency and fast convergence in the face of the gradual increase of road network size and the exponential increase of state and action space with the number of intersections. …”
