Li-Fi uses visible light communication through LED bulbs to transmit data at speeds up to 224 gigabits per second. It works by modulating the light intensity of bulbs to transmit data to a photodetector. While faster than Wi-Fi, Li-Fi has limitations in that the light must be on and signals can't pass through walls. However, Li-Fi provides more secure communication and is being tested in cities to provide internet access through street lights. In the future, Li-Fi may be integrated into most light sources to provide connectivity throughout homes and offices.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.

Este documento presenta un método para calcular las corrientes de cortocircuito en instalaciones eléctricas. Explica que es necesario calcular las corrientes de cortocircuito en diferentes puntos de una red para elegir protecciones adecuadas. Detalla dos valores de corriente de cortocircuito que deben determinarse: la máxima, que define la capacidad de corte de disyuntores; y la mínima, que se usa para seleccionar las curvas de disparo. A continuación, presenta dos métodos para realizar los cál
